The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to specify technical scheme of the present invention.
Like Fig. 1-shown in Figure 5, the disposable use retraction of the present invention safety blood taking bag comprises a blood sampling portion C, that connects successively keep sample part A and at least one blood bag 1.Blood sampling portion C, the part A that keeps sample and at least one blood bag 1 be an external conduit respectively, conduit 3, conduit 7 and conduit 8 shown in figure, and said conduit is connected to an integral body through a threeway 5.
Wherein, the blood sampling portion C comprises an overcoat 61, a core bar 62 and a blood taking needle 65, and core bar 62 is inserted in the overcoat 61, and blood taking needle 65 is connected the bottom of core bar 62.Preferably, be provided with a passage 63 in the core bar 62, passage 63 can be the passage of consistent punching bar 62, and its diameter is smaller or equal to 3mm.In the upper end of core bar 62 is one handle 623, and in handle 623, is provided with one and is connected the vertebra head with passage 63 is communicated with, makes core bar 62 through said connection vertebra head and corresponding conduit 7 connections.
Further, handle 623 is convex tendon cylinder handle or spirillum handle, and in the upper end of handle 623, establishes the spiral mouth.Operator's operation is convenient in the setting of handle 623, and the spiral mouth is convenient to entry needle and is connected on the miscellaneous part.
The blood sampling portion C also comprises a piston 64 and a needle guard 66; On the outer wall of core bar 62, be provided with a circle draw-in groove 621; Piston 64 is fastened between draw-in groove 621 and the overcoat 61, drives core bar 62 through relatively moving between piston 64 and the overcoat 61 and relatively move with overcoat 61.Adopt needle guard 66 to be set in the bottom of core bar 62, and entangle blood taking needle 65.
Simultaneously, flexibility ratio and tautness for the portion C that guarantees to take a blood sample is used adopt interference fit or matched in clearance between each parts.For example, piston 64 is an interference fit with draw-in groove 621, and piston 64 is an interference fit with overcoat 61, and core bar 62 is a matched in clearance with overcoat 61, and needle guard 66 is an interference fit with the bottom of core bar 62.
Further, be provided with a core bar screens 622 in the upper end of draw-in groove 621, the inwall upper end of overcoat 61 is provided with an overcoat screens 611.When core bar 62 is upwards lifted the top to overcoat 61; Core bar screens 622 contacts with overcoat screens 611; Core bar screens this moment 622 withholds with overcoat screens 611 each other, and core bar 62 can not upwards be lifted again, can prevent effectively that pulling force from crossing senior general's core bar 62 and lifting out overcoat 61.
In addition, for convenient for production, core bar 62 can be formed by connecting two rod members in midway, passes through vertebra head interference fit (not shown) between the said rod member.
Wherein, the part A that keeps sample comprises that a spiral base 42, a pin 41 and hold needle guard 45.Pin 41 is fixed on the upper end of spiral base 42, and spiral base 42 screws with the bottom of holding needle guard 45, pin 41 entirely is contained in holds in the needle guard 45.Further, offer a socket 421 in the upper end of spiral base 42, the lower end offers a catheter hub 422, pin 41 is fastened in the socket 421 again, and conduit 8 is connected in the catheter hub 422, and guarantees that socket 421 is communicated with catheter hub 422.Outer cover at pin 41 is provided with a sheath 44, is used for anesthesia needle 41.
Wherein, blood bag 1 is at least two a blood bag, can (not shown) in series or in parallel with each other between a plurality of blood bags 1.Like this, can satisfy different blood sampling demands.
Preferably; The upper end of threeway 5 is provided with two first guide holes 51 in the B part shown in Figure 4; The bottom is provided with one second guide hole 52; And for being communicated with in twos, the corresponding conduit 8 of the part A that keeps sample is connected to respectively in the first corresponding guide hole 51 with blood bag 1 corresponding conduit 3 between first guide hole 51 and second guide hole 52, and the blood sampling portion C is connected in second guide hole 52 through the conduit 7 of correspondence.
In addition, on the corresponding conduit 7 of blood sampling portion C, be provided with a vessel clamp 2, on the corresponding conduit 8 of the part A that keeps sample, be equipped with a vessel clamp 43.Can control the blood sampling portion C effectively and keep sample the flow of part A through corresponding vessel clamp, be convenient to operator's practical operation.
According to said structure; Concrete occupation mode of the present invention is following: after adopting said safety blood taking bag blood sampling to accomplish; Overcoat 61 in the blood sampling portion C is pushed away forward, and piston 64 relatively moves with core bar 62 and overcoat 61, slides into overcoat screens 611 places up to core bar screens 622; Blood taking needle 65 just has been hidden within the overcoat 61, and accident has not been stabbed the people to blood taking needle 65 with regard to not exposing.
In the corresponding part A that keeps sample; Pin 41 is hidden in to be held in the needle guard 45, and medical personnel will keep blood sample, directly inserts blood taking tube and holds in the needle guard 45; Blood taking tube front end plug is passed by pin 41; Blood taking tube and blood bag connect, and the blood taking tube vacuum action sucks the blood in the blood taking bag in the blood taking tube, keep sample to accomplish to pull out blood taking tube.Safety blood taking bag constructions of the present invention is simple and easy to use, can prevent effectively that blood taking needle from stabbing accident, greatly reduces the medical-risk of blood taking bag.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is limited appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite that does not deviate from principle of the present invention and essence, but these changes and modification all fall into protection scope of the present invention.
