Abstract

An integrated vascular delivery system and safety needle including: a frame having a catheter hub providing a first anchoring point and that receives a catheter that transfers fluid at an insertion site, and a stabilization hub providing a second anchoring point; a fluidic channel coupled to the catheter; a housing; a needle insertable through the frame; and a sheath telescopically engaged with the housing. The sheath couples to the frame such that needle removal from the frame transitions the sheath from a retracted position, in which the sheath exposes the needle, to an extended position in which the sheath surrounds the needle. The frame operates in a folded configuration in which each hub couples to the housing and/or sheath and in an unfolded configuration in which the first and second anchoring points are distributed around the insertion site to anchor the frame to the patient, thereby stabilizing the catheter.

1. integrated vascular delivery system

The framework 110 of integrated vascular delivery system works to be stabilized in system and the catheter on the patient.As shown in Fig. 2-3, framework 110 preferably includes the catheter hub 120 that is provided at the first anchor point 112 on the patient, be provided at the second anchor point 112 on the patient ' stable hub 130 and the cross member 140 that at least one extends between catheter hub and stable hub.In the selectable embodiment of framework 110, framework can comprise the hub of any suitable quantity and the cross member of any suitable quantity, so that framework is formed on the besieged or not besieged periphery of part with any suitable shape and size of inserting around the position 102.Framework preferably allows insertion position visual of catheter, for example by reserving the unlapped zone of opening around catheter, but selectively system can comprise the covering of the material that is transparent, translucent, opaque or any suitable type, extends to cover on the framework surface and inserts position and/or catheter.

Catheter hub 120 is configured to receive catheter 122, catheter 122 can be embedded within the catheter hub and be the part of the one of system, maybe can be the catheter that is coupled in the separation of catheter hub 120 before or after in inserting the patient, for example use the snap fit in the catheter hub 120.Selectively, any suitable part of framework can be configured to receive catheter.Catheter hub 120 preferably includes passage 124, and it is aimed at one heart with catheter, and this catheter may be received in the pin 320 that uses during the insertion of catheter in the patient.As shown in Fig. 2 D, catheter hub and/or stable hub can comprise the biometric parameter sensor 126 of temperature, blood pressure or pulse rate for example of measuring the patient.Sensor 126 can be additionally and/or any suitable parameter of sensing selectively, for example about the parameter through the fluid of catheter, for example pH or flow velocity.

Catheter hub and/or stable hub can have relatively wide and thin profile, and this can help power is distributed on the larger zone on the skin and reduces the patient to produce skin irritation, pain and other deteriorated chance.Thin profile can help to reduce hub and be hooked in or stumble at bed facility or other nigh and can make catheter in the intravenous motion and cause risk on for example catheter displacement of complication, infiltration and the phlebitic barrier.Yet catheter hub and stable hub can have any suitable shape.Catheter hub and stable hub can comprise plastics rigidity or semirigid or other suitable material and/or softer material.For example, one or two hub the two can comprise for example plastic rigidity core of silicone of the softer material of use.

As shown in Fig. 2 A, system can also comprise at least one extension 160 and/or the fluid source joint 162 that fluid are delivered to fluid passage 150 from fluid source that is coupled in catheter hub 120 and/or stable hub 130.The extension 160 that provides stress relieving when being pushed (for example handling from patient moving or care-giver) in system still can selectively be the path by any other suitable material manufacture preferably by for example polymer conduit manufacturing of flexible conduit.Extension 160 preferably grows to is enough to provide stress relieving, if necessary, is enough to reduce extension and is hooked in or stumbles chance on the nigh barrier but be as short as.In another version, fluid passage 150 and/or extension 160 can be coiled, and spring-like is to provide stress relieving.The length of extension can selectively be any suitable length, and can depend on the concrete application of system.The dimension of other of extension, for example external diameter and internal diameter also can depend on the concrete application of system.Fluid source joint 162 preferably includes the adapter (for example pole IV bag, syringe or the pump of fluid supply through pipeline) that extension is attached to fluid source.Adapter can be the cloudy luer lock connection (Fig. 4 A and 4B) of standard or the three way cock (Fig. 4 C and 4D) who usually is connected with the IV bag interface of routine.Selectively, adapter can be any suitable sun or female connector of being connected with the fluid source interface of being adapted to.In addition, luer lock connection or other fluid source joint can directly be coupled in catheter hub and/or stable hub, rather than are coupled in extension.

In the selectable form of system, system can comprise more than an extension 160 and/or fluid source joint 162, to help that the fluid from a plurality of fluid sources side by side is delivered to system.For example, in the embodiment of the system that comprises two fluid passages, system can comprise first fluid is delivered to the first extension of first fluid passage and the second extension that second fluid is delivered to the second fluid passage.Yet two extensions can be useful in the application of using of the same fluid passage 150 of the process that relates to two minutes other fluids and catheter.

Cross member 140 works with by hub 130 is stable to provide structural stability to framework 110 with respect to stablizing catheter hub 120.As shown in Fig. 2-4, framework preferably includes with catheter hub and stable hub and forms around two cross members 140 of the periphery of catheter.Two cross members can be approximately parallel, maybe can be with any intersection, nonparallel or other suitable orientation.Yet as shown in Figure 3, framework 110 can comprise the only periphery around catheter of part, for example uses a cross member to replace two.Each cross member 140 can be flexible, for example to allow catheter hub and stable hub relative to each other with a lot of degree of freedom motions, be included in displacement (and follow-up displacement at draw direction) along the compression direction of the axis of catheter, along other two axis both direction the two displacement, along the both direction of the axis of catheter the two distortion and in the two the bending of both direction of two axis along other.Especially, cross member 140 can be reversibly flexible to allow framework 110 to be in wherein catheter and to be in the folded configuration that can be coupled.One or more cross members can be tubuloses.For example, cross member can be the medical pipeline of straight substantially softness and flexible hollow channel shape, but can be any suitable structure with tube chamber.

Fluid passage 150 works that fluid is delivered to catheter from fluid source, and in certain embodiments, fluid to send from catheter, for example the fluid of removing from the patient is transferred to exterior reservoir through catheter.As shown in Fig. 2 C, at least a portion of fluid passage 150 can be fixed in the hub at least one and/or in the cross member of tubulose.As shown in Fig. 5 A-5C, at least a portion of fluid passage 150 can be additionally and/or selectively in the outside of hub and cross member.For example, at least a portion of fluid passage 150 can be moulded to the catheter hub, stablize the outer surface of hub and/or cross member.Fluid passage 150 preferably includes knuckle section 152, and fluid flows in the direction different from direction in catheter 122 therein.Especially, knuckle section 152 preferably is directed to direction with opposite direction in catheter to flow, or with the turnings of about 180 degree.The knuckle section 152 of fluid passage 150 can be fixed or be embedded in catheter hub and/or the stable hub.In one of system exemplary application, catheter is inserted among the patient, so that it thrusts end towards the direction near patient's heart, and the knuckle section of fluid passage 150 allows to support that the base of IV bag or other fluid source is retained as the head that approaches bed, or inserting the near-end at position in other mode, such as typically practice in the patient treatment environment.The quantity that can be hooked on or stumble on the nigh barrier and therefore upset the external structure of catheter and IV setting is reduced at the flow turning of the interiorization in the knuckle section 152 of fluid passage 150.Another effect of knuckle section is, if the exterior line of IV in arranging is pulled or hooks, knuckle section can make framework 110 be entered among the patient more effectively stabilisation catheter by further pulling by making catheter so.For example, catheter is placed on the distal end that makes it on the forearm in placing near the general catheter of patient's ancon therein, if exterior line was unexpectedly spurred towards the patient afterwards, so pipeline will so that the knuckle section of fluid passage 150 and catheter hub 120 towards patient's pulling, thus catheter is further spurred in patient's the blood vessel rather than catheter and goes out from the insertion section displacement.

In some version, system can comprise the fluid passage of, two or any suitable quantity.For example, second fluid passage 150 can be through the second cross member 140.Second fluid passage 150 preferably receives second fluid, and second fluid can be identical from the first fluid that is provided to first fluid passage 150 or different.As shown in Fig. 4 A-4C, system can also comprise the second extension 160 that second fluid is supplied to framework and catheter.Yet as shown in Fig. 4 D, system can comprise only extension 160 that fluid is supplied to one or more fluid passages.The fluid passage can have at minute other entrance (Fig. 4 A and 4C) of stablizing on the hub 130, maybe can be shared in the same entrance (Fig. 4 B and 4D) that the therein stream of stablizing on the hub can use valve or other fluid control device to be conditioned.In a version, the first and second fluid passages preferably are communicated with same catheter fluid ground in the catheter hub 120, are locating to be coupled in catheter along the same point (Fig. 4 A and 4B) of the length of catheter or passage or different points (Fig. 4 C).In this version, optimum system choosing ground comprise in the constrain fluids optionally one or two to catheter and therefore to patient's the flow system 154 that flows.Flow system 154 can comprise one or more valves 156, for example (Fig. 4 A and 4B), place, the junction surface between fluid passage 150 and catheter (Fig. 4 C and 4D) or any suitable place at the extension place.Flow system can be additionally and/or is selectively used pressure drop, ventilation or any suitable technology with the fluid flow between control fluid passage and the catheter.Flow system can also exist in comprising the embodiment of a fluid passage 150 only.In another version, first fluid passage and second fluid passage preferably are communicated with the catheter fluid ground with dual lumens, so that catheter tube chamber is coupled in the first fluid passage and another catheter tube chamber is coupled in the second fluid passage.In another version again, first fluid passage and second fluid passage are communicated with minute other catheter fluid ground.Other version is expanded at these versions, has three or more fluid passages.

As illustrating best in Fig. 2 D, preferably catheter hub 120 and stable hub 130 can be coupled in each other the folded configuration 114 and the first anchor point and the second anchor point are distributed on operation in the not folded configuration 116 of inserting around the position therein framework 110 therein.In order to help to realize folded configuration, framework 110 preferably allows catheter hub 120 and stable hub 130 relative to each other to move with a lot of degree of freedom.Especially, framework is preferably reversibly flexible or folding with folding toward each other catheter hub and stable hub, or with one in the hub the surface of another hub and/or below pass through.

In folded configuration 114, catheter hub 120 and stable hub 130 can be coupled in each other, thus framework are fixed in the folded configuration.When catheter hub and stable hub were coupled, these hubs were with respect to the identical motion of pin 320 experience that enters in catheter hub 120 and the catheter, for example during the insertion in the patient of catheter.In the first version, catheter hub 120 and stable hub 130 can be coupled in each other by the interaction of pin 320 with catheter hub 120 and/or stable hub 130.In an embodiment of this version, as shown in Fig. 6 A-6D, stablize hub 130 and comprise extension 132, and catheter hub 120 can comprise the depressed part of groove 128 or other reception extension 132, but catheter hub 120 can comprise that extension 132 and stable hub 130 can comprise groove 120 in another embodiment.Extension 132 defines through hole 134, so that when extension 132 was inserted in the groove 128, through hole 134 was aimed in fact with the pin receive path 124 of catheter hub 120.In this version, framework 110 can be during the catheter in the patient inserts, by the user (for example doctor) that catheter hub and stable hub are coupled by pin 320 is folded into folded configuration through the passage 124 of catheter hubs 120 and the through hole 134 that passes through extension 132.Selectively, during manufacture, for example during assembling and/or packing, framework 110 can be folded and/or pin 320 can be through extension and the groove of hub.When pin 320 was recalled from hub, hub can be taken off coupling and framework 110 and can be unfolded and be folded configuration not.As shown in Figure 7A and 7B, extension 132 can be when extension no longer is required, for example when framework 110 in folded configuration not and be ready to the patient fixedly the time, collapsiblely enter in the hub.Catheter hub and stable hub can comprise extension and/or the groove of, two or any suitable quantity.Yet catheter hub 120 and/or stable hub 130 can be additionally and/or (are for example used the housing around pin) selectively in any suitable manner and interact to help the optionally coupling of catheter hub and stable hub with pin.

In the second version, as shown in Figure 9, catheter hub 120 and stable hub 130 can be coupled in each other indirectly by being coupled in mutually housing.For example, as shown in Figure 9, in the folded configuration of framework, the catheter hub can be coupled in epitheca and indirectly is coupled in housing, and stable hub can be coupled in housing, and hub and framework is fixed in the folded configuration thus indirectly is coupled.

In the 3rd version, as shown in Figure 10-12, catheter hub 120 and stable hub 130 can be coupled in each other indirectly by being coupled in mutually epitheca.In the first embodiment, as shown in Figure 10 A-10D, the catheter hub can be coupled in epitheca, and stable hub can comprise the extension that can aim at catheter hub and/or epitheca, additionally pass extension and catheter hub so that pass the pin of epitheca, be coupled thus catheter hub and stable hub are to a certain extent similar in appearance to the first version of hub coupling, except extension is received by epitheca.With in the first version of hub coupling similarly, extension can be contractile.In a second embodiment, stable hub can be by being coupled in epitheca in the surface that is entered epitheca by interference fit or snapping, and catheter hub and stable hub thus indirectly are coupled.For example, as shown in Figure 11 A-11B, epitheca can comprise the recess of profile of at least one part of the periphery with stable hub, for example stablizes hub and is assemblied in two projections or stake between it.In order to help such interference fit or snap fit, stablize hub and/or epitheca and can comprise for example molded section of silicone, isoprene, thermoplastic elastomer (TPE) or any suitable material of soft compressible material.In the 3rd embodiment, as shown in Figure 12 A-12B, catheter hub and/or stable hub can use connection part to be coupled in epitheca.In the present embodiment, stable hub has the extension that possesses through hole, and the extension with through hole can be embedded in when framework is in folded configuration in the catheter hub or between catheter hub and epitheca.Connection part can be laterally or longitudinally through the catheter hub, stablize extension in the hub and the pin of epitheca and/or housing.Yet connection part can be the connection part of the manual coupling of any suitable breech lock of being controlled by user or other the folded configuration that is provided for fixed frame.

In the 4th version, the catheter hub, stablize hub, epitheca and/or housing and latch system mutually coupling be coupled in framework so that framework is fixed in the folded configuration and epitheca.For example, catheter hub 120, stablize in hub 130 and the epitheca 330 each comprise at least one extension (for example boss or arm) or at least one groove with one extension in the part that receives other so that the interlocking of framework and epitheca.For example, as shown in Figure 13 A-13D, catheter hub 120 is included in the groove 172 of its proximal lateral, stablizes the stable hub boss 174 of distal side and the epitheca 330 that hub 130 is included in it and comprises epitheca boss 176 and/or the side arm 178 that at least one extends from the distal end of epitheca.As shown in Figure 14, when framework is in folded configuration, groove, boss and/or side arm interlocking.Especially, (1) epitheca side arm 178 is coupled in the proximal end (Figure 14 A and 14B) of catheter hub, so that the catheter hub is seated in the epitheca, (2) the stable hub boss 174 on the stable hub that is reversed is coupled in catheter hub groove (Figure 14 C), and the epitheca boss 176 on (3) epitheca is coupled in and stablizes hub groove (Figure 14 D and 14E).In other embodiment, the different combination of the extension that the different part of framework, epitheca and pin housing can comprise mutual coupling and groove, snapping section, magnet, breech lock and/or any suitable retention mechanism.

In the 5th version, catheter hub 120 and stable hub 130 can be coupled in each other thus indirectly by interacting with the 3rd structural detail mutually, are coupled in each other.For example, as shown in Figure 8, when framework 110 is in folded configuration, piece 136 can be coupled in catheter hub 120 and stable hub 130 the two.Have concrete geometric configuration although piece 136 is shown as in Fig. 8, piece can comprise switch, breech lock, stopper and/or any suitable securing member or other mechanism.Piece 136 remove the coupling of taking off that can help catheter hub 120 and stable hub so that framework can be in folded configuration not.As another embodiment, when framework is in folded configuration, pin 320 can be coupled in catheter hub 120 and stable hub 130 the two, for example during catheter inserts.After catheter inserts, pin remove the coupling of taking off that can help catheter hub 120 and stable hub.

In the 6th version, catheter hub 120 and stable hub 130 can slidably be coupled in each other.For example, one in the hub can have side trench or passage, and another hub can have lateral ridge section, and when framework 110 was in folded configuration, the groove of this lateral ridge section and another hub meshed slidably.Another embodiment of this version can comprise the boss that is inserted in the groove, or any suitable mechanism.

Epitheca 330 can comprise the matching characteristic that makes epitheca can be coupled in framework or other suitable medical treatment device.In a version, the distal end of epitheca is adapted to mechanically be coupled in medical treatment device.In a preferred embodiment, as shown in Figure 34 A-34E, matching characteristic comprises the pawl 342 that longitudinally extends from the distal end of epitheca 330.Pawl 342 is preferably flexible and be coupled in corresponding matching characteristic (for example outside joint portion, otch or pouch) on the medical treatment device.Each pawl can be coupled in the division part 340 of the distal end of epitheca, and preferably is coupled in the suppressor boss 351 of slider.For example, as shown in Figure 34 F, each division part or pawl can define the suppressor groove 138 of minute other suppressor boss 351 that receives epitheca.In a version, the profile (Figure 34 A) that pawl can have an approximate arc is with the part of the sub-circular that meets medical treatment device.In other version, pawl can comprise hook-shaped end 344 (Figure 36 A and 36B) and/or the platform 346 (Figure 37 A and 37B) that disposes for the specific corresponding feature on medical treatment device and/or the slider 350.In mechanically being coupled in other version of medical treatment device, epitheca 330 can extend beyond the distal end of housing when epitheca is in retracted position, so that the distal end of epitheca can be seated in the passage (for example isolator or other acceptance division) of medical treatment device.For example, medical treatment device can fetter the distal end of epitheca.As another embodiment, the distal end of epitheca 330 can comprise with medical treatment device in the extension of corresponding depressed part coupling, or medical treatment device can comprise with epitheca 330 on the extension of corresponding depressed part coupling.What the distal end of epitheca 330 can comprise other is used for being seated in feature in another receiving unit of isolator or medical treatment device, for example has to the taper slightly that is assemblied in the narrower diameter in the isolator, such as the friction characteristic of the constraint in isolator that can comprise epitheca 330 of flank or spine.The distal end of epitheca can be additionally and/or is selectively used magnet, binding agent, springlock, securing member or any suitable mechanical means to be coupled in medical treatment device.

In another version, the distal end of epitheca 330 is adapted to manually be coupled in framework.For example, as shown in Figure 34 A, epitheca can comprise the maintenance boss 348 that extends from the distal end of epitheca, and it is provided for pressing the finger rest that keeps boss against medical treatment device, and epitheca and medical treatment device thus manually are coupled.The protuberance that keeps boss laterally to stretch out or extend from epitheca with any suitable direction.Keep boss 348 to provide auxiliary to user, be close to medical treatment device when housing and pin 320 are spurred away from medical treatment device ground, as counteracting force epitheca is remained.As shown in Figure 34 D, keep boss 348 can comprise the bridge of the division part of connection epitheca stopper.Selectively, epitheca can comprise a plurality of maintenance boss, for example a maintenance boss 348 that extends from each division part 340 or the pawl 342 of epitheca.Keep boss 348 can comprise for helping user that the maintenance boss is remained the feature of being close to medical treatment device, for example the spine of lip, increase friction or for example silicone of coating that rubs.Keep boss can comprise binding agent and/or the mechanical attachment that the maintenance boss is coupled in medical treatment device, for example pin, snapping or breech lock.

In preferred embodiments, slider 350 works optionally to regulate the bonding force between epitheca and the medical treatment device.Slider 350 can further help epitheca 330 is locked in the extended position on the distal end of pin.Slider 350 longitudinally extends and is meshed slidably with epitheca and/or housing along at least a portion of epitheca 330 and/or housing, so that housing, epitheca and slider are relative to each other longitudinally movable.As shown in Figure 35 A-35E, slider 350 can comprise planar section 352 and epitheca insertion portion 346.Planar section preferably smooth in fact and with the slide ground engagement of housing, but can selectively be curved surface.Planar section 352 can comprise groove 356 (Figure 30 A) and/or the spine 358 (Figure 30 B) with track 314 complementations of housing 310, or any suitable profile.Epitheca insertion portion 354 is preferably located on the distal segment of slider, and telescopically is engaged in the epitheca 330.As shown in Figure 35 D, the epitheca insertion portion can have the cross-sectional profiles of approximate arc, or the profile of any suitable and cross-sectional profiles complementation epitheca, is meshed slidably with epitheca to allow the epitheca insertion portion.Epitheca insertion portion 354 preferably define allow pin 320 through and enter hole 362 in the epitheca insertion section.Hole 362 can be circle hole, groove or any suitable opening, to allow the relative longitudinal translation of slider 350 and pin 320.In certain embodiments, as shown in Figure 41, slider 350 can comprise protuberance 356, protuberance 356 is connected with the flexible pawl interface of epitheca 330, so that protuberance 368 triggers pawl for " opening " configuration when slider is recalled from medical treatment device, automatically epitheca 330 and medical treatment device are taken off coupling thus.

Epitheca insertion portion 354 preferably includes suppressor, suppressor and epitheca optionally mesh, so that when suppressor was meshed with epitheca, suppressor strengthened the coupling to medical treatment device of epitheca, and when suppressor was closed from the epitheca drop out of gear, suppressor reduction epitheca was to the coupling of medical treatment device.In preferred embodiments, as shown in Figure 35 F, slider 350, particularly the epitheca insertion portion 354, can comprise division part 340 that at least one can be inserted in epitheca or the suppressor boss 351 in the suppressor groove 338 on the pawl 342.In the present embodiment, when epitheca be contracted and pawl 342 around and when controlling medical treatment device, suppressor boss 351 is coupled in suppressor groove 338 and the anti-in fact claw stop of suppressor boss relative to each other moves, thus strengthened flexible pawl 142 controlling on medical treatment device.When epitheca is extended (for example housing is moved away from medical treatment device) on proximal direction, the suppressor boss becomes and is taken off coupling from suppressor groove 338, make flexible pawl 342 more freely with respect to other motions, the controlling on medical treatment device of the flexible pawl 342 that weakens thus.In other words, the suppressor boss 351 on the slider optionally being coupling in suppressor groove 338 on the epitheca effectively regulates for the deflection pawl and epitheca is taken off the amount of the needed power of coupling from medical treatment device.

Slider 350 preferably includes when epitheca 330 is in extended position in abutting connection with the near-end joint portion 364 of housing stopper and/or in abutting connection with the distal joint section 366 of epitheca stopper.When epitheca 330 was in extended position, near-end joint portion and distal joint quality award from the ministry selection of land were fixing respectively with respect to the two sliding position of housing and epitheca, and this fixes epitheca 330 indirectly with respect to housing, thus epitheca 330 is locked in the extended position.Selectively, system can comprise any suitable locking mechanism that is used for epitheca is locked in extended position.As in Figure 35 E, illustrating best, the near-end joint portion 364 of slider 350 preferably on the proximal part of slider and be laterally outside extension in abutting connection with the housing stopper, boss for example.Near-end joint portion 364 can or can not comprise similar in appearance to the hole in the hole 362 of epitheca insertion portion, passes through through the near-end joint portion to allow pin 320.The distal joint section 366 of slider 350 is extension preferably, for example fritter or the capture unit in the hole 336 of the seizure on the epitheca insertion portion at the epitheca stopper.Selectively, distal joint section 366 can be on any suitable distal portions of slider.As shown in Figure 49 and 41, near-end joint portion and distal joint section can be outstanding towards the bottom of slider 350, but they can corresponding to the housing stopper in the place on the housing and any suitable direction in the place on epitheca of epitheca stopper outstanding.In other version, near-end joint portion and distal joint section can any suitable place on slider in and can each be hole or extension corresponding to the type of the housing stopper on the housing and the epitheca stopper on the epitheca.

Generally in preferred embodiments, the part that the distal portions of epitheca is coupled in medical treatment device relates to flexible pawl (it is the extension of the division part on the epitheca) is coupling in around the medical treatment device.As shown in Figure 38 A, epitheca preferably is contracted, and the suppressor boss 351 on the slider is inserted in the suppressor groove 338 that divides on the part.When the suppressor boss is inserted in the suppressor groove, laterally move separately the coupling between the reinforcement of suppressor boss or lock pawl and the medical treatment device by anti-in fact claw stop.When housing and slider are spurred away from medical treatment device ground, when thus epitheca being spurred with respect to pin, the distal joint section of slider is temporarily in abutting connection with the first epitheca stopper 336, so that suppressor boss 351 keeps being engaged in the suppressor groove 338 and epitheca keeps being coupled in medical treatment device.In this intermediate steps, the distal joint section of slider preferably overcomes the shearing force that is caused by the friction between housing and the slider against the first epitheca stopper.As shown in Figure 38 C, when housing during by the pulling of medical treatment device ground further away from each other, housing spurs slider away from medical treatment device ground, until the first stopper 336 is crossed by distal joint section 366 and in abutting connection with the second epitheca stopper 337, the near-end joint portion 364 of slider is in abutting connection with housing stopper 316 at this moment.In addition, when slider was crossed the first stopper 336, the part of any other of medical treatment device (for example the stable hub 130 in the integrated vascular delivery system is described above) can be discharged and be taken off coupling from the safty pin system.In addition, as shown in Figure 38 B, when distal joint section when the second epitheca stopper, suppressor boss 351 closes from suppressor groove 338 drop out of gears, coupling between pawl and the medical treatment device thus weakens.For example, after this last step, user can easily provide (around the pin) epitheca that is enough to separate extension and the power of medical treatment device.

In selectable embodiment, as shown in Figure 39-41, slider works automatically trigger the coupling of taking off between epitheca 330 and the medical treatment device when pin is recalled from medical treatment device.In the present embodiment, as shown in Figure 39, pawl 342 can be biased into its median claw be tending towards controlling the matching characteristic on the medical treatment device " sealing " configuration 341 in.As shown in Figure 40, pawl 342 can be handled with deflection, swing or with other mode its median claw that moves and laterally be moved in separately " opening " configuration 343, make thus the coupling of taking off of epitheca 330 and medical treatment device 302 become possibility, for example after epitheca has been pulled in its extended position.Pawl 343 can automatically be handled in " opening " configuration when housing and/or slider 350 are spurred away from medical treatment device on proximal direction, automatically epitheca 330 is taken off coupling from medical treatment device thus.In the present embodiment, as shown in Figure 41 E, slider 350 comprises the protuberance 356 that is connected with the flexible pawl interface of epitheca 330, so that when slider is recalled from medical treatment device, protuberance 368 triggers pawl in " opening " configuration, automatically takes off thus coupling epitheca 330 and medical treatment device.

In the second preferred embodiment, as shown in Figure 42 A and 42B, safty pin system 400 comprises: housing 410, and it comprises the pin installation portion 412 that is coupled in base 414, base 414 is positioned at the approximate axial center of pin installation portion 412 in housing 410; Pin 412, it has the distal end that can pass framework or other suitable medical treatment device and the proximal end that is coupled in pin installation portion 412; And epitheca 430, itself and housing 410 telescopically mesh and have the distal end wall 444 that defines pin hole 446 and the long rails 442 that is meshed slidably by the base 414 with housing 410.Epitheca 430 is retracted position 432 and the wherein in fact operation in the extended position 434 of the distal end of pin of epitheca of the distal end of epitheca exposed needle therein.Similar to the epitheca of the first preferred embodiment of safty pin system, epitheca 430 preferably can be coupled in medical treatment device so that pin from medical treatment device remove an epitheca 430 with respect to the pin pulling, thus epitheca is converted to extended position from retracted position.Safty pin optimum system choosing ground also comprises locking mechanism 450.In the preferred embodiment of safty pin system, when epitheca was in extended position, the proximal part of epitheca 430 was in abutting connection with the housing stopper or catch in housing, and locking mechanism 450 constrains in epitheca in the extended position.In a version, locking mechanism 450 is the housing stoppers that comprise the springlock cantilevered arm, and the free end of springlock cantilevered arm is configured to when epitheca is in extended position the proximal part in abutting connection with epitheca.Yet, can use any suitable locking mechanism.

In certain embodiments, housing 410 also comprises one or more handles 418, and one or more handles 418 can be controlled and handle to user with the handling safety needle system.Handle is preferably incorporated in and becomes two possible side handle parts so that use a hands fixedly to control on the opposite side of housing.The side handle part can be maybe can be relative wide and extend (Figure 45 A) along the length of the essence of housing along the length of housing, relatively short and thin (Figure 43 A).Similar to the handle of the first preferred embodiment of system, handle 418 can comprise such as the feature of ergonomics profile, for improvement of the spine of the friction in the handle part, such as padded coaming or any suitable adding part of silicone.In addition, the version of other of handle can comprise less or more handle part (for example single knob), and can be specific for concrete application.In certain embodiments, handle can be further used as the hub carriage and work, and for example be used for to receive other suitable part of catheter hub 120 or stable hub 130 or medical treatment device.

As shown in Figure 43 C, the distal end of housing 410 can also comprise the crosspiece 417 that helps to support epitheca 430 when epitheca is in extended position.Crosspiece 417 preferably extends beyond the distal end of housing, preferably supports the epitheca that extended at least one downside of housing with opposing gravity ground, and can be smooth, crooked or any geometric configuration for the support epitheca.Crosspiece can comprise that other being used for helps the feature fixing or epitheca that support has been extended, for example handle part of coat with rubber or tooth, or securing member, for example magnet, clip or binding agent.In addition, crosspiece can be used hinge and attach to housing, for example is used for folding so that system is compacter before using and/or between the storage life afterwards.Yet crosspiece can have any other suitable geometric configuration and/or layout.

The epitheca 430 of the safty pin system of the second preferred embodiment similarly works with the epitheca of the first embodiment of system.As illustrating best in 45A figure, epitheca 430 preferably slidably mates with housing 410, so that epitheca telescopically passes through in the passage of housing.Epitheca 430 be therein epitheca by in the housing 410 of retracting at least in part and the retracted position 432 reconciling the exterior and interior of the body sheaths 430 of the distal end of exposed needle are extended from housing 410 and exercisable at least one around the extended position 434 of the distal end of pin in fact.As shown in Figure 44-45, epitheca comprises the long rails 442 that other the part with base or housing meshes slidably, and the distal end wall 444 that helps to cover the distal end of pin when epitheca is in extended position.

In a preferred embodiment, epitheca 430 comprises two parts, comprises near-end epitheca part 430a and far-end epitheca part 430b.As shown in Figure 44 A-44E, near-end epitheca part 430a and far-end epitheca part 430b are assembled to form integrated epitheca main body.As shown in Figure 44 E, near-end epitheca part 430a preferably includes snapping breech lock 431a and the far-end epitheca partly preferably includes the snapping hole 431b that receives snapping breech lock 431a with the snap fit fastening means.Yet, additionally and/or selectively, far-end epitheca part can comprise that snapping breech lock and near-end epitheca part can comprise the snapping hole, or near-end epitheca part and far-end epitheca partly can pass through screw thread, interference fit, magnet, binding agent or in any suitable manner by attached.Near-end epitheca part and far-end epitheca partly preferably are assembled in the housing 410, be bonded on base and/or the housing inboard other the inside protuberance around.At assembly process, far-end epitheca part can enter from the distal end of housing housing 410 and near-end epitheca part can enter housing from the proximal end of housing.In another version, epitheca comprise epitheca part and, preferably in long rails as described below, include and help the feature of in housing, assembling.

The long rails 442 of epitheca 430 works to guide the transformation between retracted position and extended position of epitheca.Long rails is groove preferably, but can selectively be the groove of engaged with base slidably, maybe can comprise the combination of single or multiple groove and/or groove.Long rails 442 preferably is parallel in fact the longitudinal axis of epitheca, from the proximal end of the epitheca distal end towards epitheca, and meshes slidably with another feature of base and/or pin installation portion or housing 410.

As shown in Figure 45 and 46, in single-piece epitheca version, long rails preferably includes a series of by the reeded part of adjoining of arc ground skew, and overlapping two such parts with the single track that forms the vicissitudinous width of tool at least in part more preferably.In preferred embodiments, illustrate best in " expansion " view such as the track in Figure 45 C, the first rail portion 442a longitudinally extends to from the proximal end of epitheca along epitheca 430 partly along the point of the length of epitheca.In the present embodiment, the second rail portion 442b preferably is parallel to the first rail portion and extends in certain deviation angle of circumferential offset and along the whole in fact length of epitheca 430 from the first rail portion.In two rail portion each is preferably the same wide with the width of the base of housing approx, or slightly wider than the width of the base of housing, so that when base is meshed slidably with track 442, when epitheca 430 telescopically moved in housing 410, base 414 was freely mobile in long rails.In preferred embodiments, the first rail portion 442a slidably engaged with base allowing epitheca 430 in the proximal direction process, until the end of the first rail portion, particularly, for example at the assembly process of safty pin system, epitheca is retracted in the housing at least in part.The second rail portion 442b preferably with around the different angle of circumference of epitheca 430 engaged with base slidably, passes through towards complete retracted position at proximal direction to allow epitheca further.The second rail portion 442b is engaged with base 414 also preferably, with for example cover with the safty pin system pin during, allow epitheca to pass through at the extended position of distal direction towards epitheca.Although the first and second rail portion are preferably shared an edge at least in part, in other version, track 442 can comprise the rail portion with any suitable arrangement of any suitable quantity.For example, the first and second rail portion can be offset relatively large deviation angle, so that the first and second rail portion are not shared the edge.In addition, as shown in Figure 46 A, the long rails part can be engaged by cross track 442c or other open access (for example distal end of the opening of the epitheca as shown in Figure 46 B), so that the rotation in housing of epitheca can be advanced base between rail portion.

The part of other of long rails 442 and/or epitheca 430 preferably also be defined in epitheca the close end office work prevent that the epitheca that has extended from fully leaving the seizure part 438 of housing 410.Capture unit 438 preferably is arranged on the close end office of epitheca and in abutting connection with base and/or pin installation portion when epitheca is in extended position.Capture unit 438 can be fitted in the alcove space 415 of housing.Another catches mechanism, and for example spring or breech lock can be additionally and/or be used to selectively prevent that epitheca from fully leaving housing.Among one or more in these versions, epitheca preferably is limited to slide and exceeds specific point extending (far-end) direction.

The distal end wall 444 of epitheca 430 works to cover in fact the distal end of pin when epitheca is in extended position, and when epitheca 430 is in retracted position, work as the stopper against pin installation portion and/or base further, fully be retracted in the housing 410 to prevent epitheca.Distal end wall 444 be formed on the distal end of epitheca in fact completely or the face of part, and define even as big as receiving and allow pin hole 446 or the hole of process of at least a portion of pin.Pin hole 446 can be in the distal end wall of epitheca opening (Figure 46 B) or can be in the guide that extends beyond distal end wall or part pin covering (Figure 49).For the epitheca retraction is limited to certain point (for example less than in the housing 410 of fully retracting, so that the distal end of epitheca still extends beyond the distal end of housing), distal end wall 444 can work as epitheca in retracted position the time in abutting connection with pin installation portion and/or base, or additionally and/or selectively the proximal end of epitheca can be against proximal end wall or another stopper in the housing 410.In in these modes at least one, epitheca is preferably prevented slip to exceed at the specific point that shrinks (near-end) direction.

Similar in appearance to the epitheca of the first preferred embodiment of system, the distal end of epitheca 430 is adapted to mechanically and/or manually be coupled in medical treatment device.

The locking mechanism 450 of safty pin system works to constrain in the extended position to epitheca 430 and prevents that epitheca is back to retracted position from extended position.In certain embodiments, the safty pin system can be included in two or more locking mechanisms in epitheca 430 and/or the housing 410.In a version, as shown in Figure 47 A-47D, locking mechanism 450 can be coupled in epitheca 430 and/or housing 410.For example, locking mechanism 450 can be the boss 452 that is coupled in epitheca, corresponding capture unit 454 in the boss 452 engagement housings 410 or other stopper, for example near the capture unit 454 in (or other the suitable place in the housing) base and pin installation portion or other stopper are to be locked in epitheca in the extended position in fact.In the single-piece epitheca, boss 452 is preferably near the proximal end of epitheca.In the two pieces type epitheca, boss can be positioned on near-end epitheca part or the far-end epitheca part.What boss preferably made epitheca 430 becomes possibility in the process on the proximal direction (for example only in assembling) in housing 410, simultaneously in fact when epitheca is in extended position, when boss engages catch section, prevent the process on proximal direction of epitheca.For example, as shown in Figure 47 B, assembly process when epitheca 430 by at proximal direction when entering in the housing 410, epitheca can be rotated to specific angle, so that base and/or pin installation portion can move freely epitheca preferably the wall deflection of boss towards housing 410 at proximal direction in housing 410.As shown in Figure 47 C and 47D, in the operating period of safty pin system, when epitheca is pulled outwardly moving extended position to it, the capture unit of the end engagement housing that barb is arranged of boss and stopping on the capture unit of housing prevents in fact thus the motion on proximal direction of epitheca and epitheca is constrained in its extended position.
