Abstract
A PIVC includes a catheter adapter having a catheter that extends distally from the catheter adapter, and an introducer needle that inserts through the catheter. The introducer needle has a grip component at a proximal end of the introducer needle. The grip component extends outwardly and distally to form a winged grip adjacent the catheter adapter when the introducer needle is inserted within the catheter. The grip component can be rotatable within the catheter adapter to allow repositioning of the winged grip with respect to the catheter adapter.
Description
- The present invention relates generally to non-integrated peripheral intravenous catheters. More particularly, the present invention is directed to non-integrated peripheral intravenous catheters that include a winged grip.
- A winged infusion set is a device that is commonly used to access a peripheral vein either for intravenous injection or for blood draw. An example of a
winged infusion set 700 is shown inFIG. 7 .Winged infusion set 700 comprises aneedle 701,wings 702 within whichneedle 701 is positioned, andextension tubing 703 that is connected to a proximal end ofneedle 701. A proximal end ofextension tubing 703 may include anadapter 704 or other structure for connecting another device (e.g. a vacuum tube or a syringe) to winged infusion set 700. - Winged
infusion set 700 is an example of an integrated intravenous device. Integrated refers to the fact thatextension tubing 703 is integrated with (or is not removed from)needle 701. In winged infusion set 700,needle 701 also remains within the patient's vasculature throughout the use of winged infusion set 700. In other words,needle 701 functions as a catheter through which fluids are injected into the patient's vasculature and/or blood is withdrawn from the patient's vasculature. - Wings 702 provide a gripping surface during insertion of
needle 701. Typically, the clinician will graspwings 702 between a thumb and forefinger which facilitates insertion ofneedle 701 at a shallow angle. For this reason, a winged infusion set is oftentimes preferred by clinicians when accessing a peripheral vein. - The integrated nature of winged infusion set 700 also minimizes the risk of blood exposure during vascular access. Because
needle 701 remains within the patient's vasculature and becauseextension tubing 703 is connected toneedle 701, there is little possibility for blood to escape from winged infusion set 700 (other than through the intended exit point at the proximal end of extension tubing 703). - Winged infusion sets, however, have various disadvantages when compared to other peripheral intravenous devices such as a non-integrated peripheral intravenous catheter. For example,
needle 701 is typically made of steel which is more likely to cause vein damage than polymeric catheters. In particular, the sharpened tip ofneedle 701 may cut, scrape, rupture, or otherwise damage the vein wall whileneedle 701 is inserted intravenously. For this reason, winged infusion sets are not typically left within the patient for extended periods of time. As a result, if the patient requires multiple vasculature accesses, the patient will likely have to be punctured multiple times sinceneedle 701 is typically not left within the vasculature between accesses. - The present invention extends to non-integrated peripheral intravenous catheters (PIVCs) that include a winged grip. The winged grip PIVCs can be used in a similar manner as integrated winged infusion sets while providing the benefit of an over-the-needle catheter. The winged grip PIVCs, in some embodiments, can also provide blood control features to minimize the risk of exposure to blood. In this way, clinicians that are accustomed to using integrated winged infusion sets can transition to using non-integrated PIVCs without the concern of an increased risk to blood exposure.
- The blood control features, in some embodiments, can be configured to allow multiple accesses to the patient's vasculature thereby enabling a winged grip PIVC to be left within the patient's vasculature for longer periods of time and across multiple accesses. In some embodiments, the winged grip can be adjustable while retaining a fixed orientation of the needle bevel to the clinician's grip.
- In some embodiments, at least a portion of the winged grip can be formed as part of the introducer needle. For example, a grip component can extend outwardly from the introducer needle to form a winged grip. In some embodiments, the grip component can also function to secure the introducer needle to the catheter adapter of the PIVC.
- In a first example embodiment, the present invention is implemented as a PIVC that comprises a catheter adapter having a catheter that extends distally from the catheter adapter, and an introducer needle that inserts through the catheter. The introducer needle has a grip component at a proximal end of the introducer needle. The grip component extends outwardly and distally to form a winged grip adjacent the catheter adapter when the introducer needle is inserted within the catheter.
- In the first example embodiment, the catheter adapter can include a winged grip that extends outwardly from the catheter adapter. The catheter adapter can also include a blood-control feature for preventing blood from flowing proximally through the catheter adapter. The blood-control feature can be configured in some cases to be actuated multiple times to allow blood to flow proximally through the catheter adapter.
- In the first example embodiment, the grip component can secure the introducer needle to the catheter adapter. In some cases, the grip component can be rotatable within the catheter adapter to allow the repositioning of the winged grip relative to the catheter adapter. In some cases, the introducer needle can include a needle shield for shielding a tip of the introducer needle.
- In a second example embodiment, the present invention is implemented as a PIVC that comprises a catheter adapter having a catheter extending distally from the catheter adapter. The catheter adapter includes a first winged grip that extends outwardly from the catheter adapter. The PIVC also comprises an introducer needle that extends through the catheter. The introducer needle includes a grip component positioned at a proximal end of the introducer needle. The grip component forms a second winged grip.
- In the second example embodiment, the grip component can secure the introducer needle within the catheter adapter including, in some cases, being rotatable within the catheter adapter thereby allowing the first winged grip to be repositioned with respect to the second winged grip. In some cases, the grip component may also include a vent for venting gases contained within a lumen of the introducer needle. The catheter adapter may also include a blood-control feature for preventing blood from flowing proximally through the catheter adapter.
- In a third example embodiment, the present invention is implemented as a PIVC comprising a catheter adapter having a catheter extending distally from the catheter adapter, and an introducer needle that extends through the catheter. The introducer needle includes a grip component positioned at a proximal end of the introducer needle. The grip component secures the introducer needle to the catheter adapter and forms a winged grip that extends outwardly from the introducer needle.
- In the third example embodiment, the winged grip can extend distally along the introducer needle such that the winged grip extends alongside the catheter adapter when the introducer needle is secured to the catheter adapter. The grip component can be rotatable within the catheter adapter to enable repositioning of the winged grip around a portion of the catheter adapter. The catheter adapter may also include a winged grip.

FIG. 7 is a top perspective view of a prior art winged infusion set. -
FIG. 1 illustrates anexample PIVC 100 that is configured in accordance with one or more embodiments of the invention.PIVC 100 includes acatheter adapter 110 and anintroducer needle 121.Catheter adapter 110 includes acatheter 111 that extends distally from the catheter adapter.Introducer needle 121 includes agrip component 120 within whichintroducer needle 121 is secured and from whichintroducer needle 121 extends distally. - When
introducer needle 121 is inserted through catheter 111 (which would be the case prior to insertingcatheter 111 into a patient's vasculature),grip component 120 is positioned at a proximal end ofcatheter adapter 110 as is shown inFIG. 1 . -
Grip component 120 includes or forms awinged grip 122.Winged grip 122 comprises a portion of grip component 120 (whether integrally or separately formed from grip component 120) that extends distally along and outwardly fromcatheter adapter 120 whengrip component 120 is positioned at the proximal end ofcatheter adapter 110. In this way,winged grip 122 forms a surface that a clinician can grip while insertingintroducer needle 121 into a patient's vasculature. -
FIG. 1A illustrates an exploded view ofPIVC 100 showingintroducer needle 121 removed fromcatheter adapter 110. Oncecatheter 111 is placed intravenously,introducer needle 121 can be withdrawn fromcatheter adapter 110 as shown by pulling proximally ongrip component 120. -
Grip component 120 can include adistal portion 123 that is sized and shaped to be inserted within the proximal end ofcatheter adapter 110. In some embodiments,distal portion 123 can be circular and have a relatively smooth outer surface thereby allowinggrip component 120 to be freely rotated within the proximal opening ofcatheter adapter 110. In such embodiments, the diameter ofdistal portion 123 can be slightly larger than the diameter of the proximal opening ofcatheter adapter 110 so thatgrip component 120 can be secured tocatheter adapter 110. However, in other embodiments,distal portion 123 need not be configured to securegrip component 120 tocatheter 110. In such cases, the friction betweenintroducer needle 121 andcatheter 111 may be sufficient to preventintroducer needle 121 from separating unintentionally fromcatheter adapter 110. - In other embodiments, distal portion 123 (as well as an inner surface of catheter adapter 110) can include threads or other structure for securing
grip component 120 withincatheter adapter 110. In such embodiments, the threads or other structure may also be configured to limit the rotation ofgrip component 120 withincatheter adapter 110. Limiting the rotation ofgrip component 120 withincatheter adapter 110 can facilitate proper positioning ofwinged grip 122 as will be further described below. -
FIG. 2 illustrates anotherexample PIVC 200 that is configured in accordance with one or more embodiments of the invention. Similar toPIVC 100,PIVC 200 includes acatheter adapter 210 having acatheter 211 and anintroducer needle 221 having agrip component 220 that formswinged grip 222. However, in contrast toPIVC 100,catheter adapter 210 also includes awinged grip 212.Winged grip 212 extends outwardly fromcatheter adapter 210. In some embodiments,winged grip 212 can be rigid, while in others,winged grip 212 may be flexible or incorporate a hinge to allow movement ofwinged grip 212 with respect tocatheter adapter 210. - As shown in
FIG. 2A ,introducer needle 221 can be removed fromcatheter adapter 210 as described with respect toFIG. 1A above.Grip component 220 can include adistal portion 223 that can be configured in any of the ways described above with respect todistal portion 123. - As shown in each of
FIGS. 1 , 1A, 2, and 2A,winged grip winged grip - Introducer needles 121 and 221 are configured for insertion using the right hand. In particular, the clinician would typically grasp
PIVC winged grip 122/222 and the fingers wrapped underneathwinged grip 122/22 and/orcatheter adapter 110/210. To configure an introducer needle for left handed use, the introducer needle would be rotated 180 degrees with respect to the grip component from what is shown inFIGS. 1 , 1A, 2, and 2A thereby causing the winged grip to extend to the left when the beveled distal tip is facing upward. -
FIG. 3 illustrates anexample introducer needle 321 that includes agrip component 320 forming awinged grip 322.Grip component 320 includes avent 320 a for venting gases from withinintroducer needle 321. For example, vent 320 a can be formed by incorporating amaterial 325 withingrip component 320 that is permeable to gas but not to fluids. Although not shown, vent 320 a may alternatively be formed as one or more openings withingrip component 320 that are sufficiently large to allow the passage of gas, but that are sufficiently small to prevent or minimize the flow of fluids through the openings. Accordingly, any type of vent that can be formed withingrip component 320 for venting gases from withinintroducer needle 321 can be employed in embodiments of the present invention. - A grip component of an introducer needle can be configured with a vent to facilitate flow of blood into the introducer needle. This flow of blood, or flashback, can provide visual feedback to the clinician that the introducer needle has been properly placed within the vasculature of the patient. Although not shown in
FIG. 3 , an introducer needle in accordance with one or more embodiments of the invention can include a notch or opening to allow the blood to flow into the catheter where it will be visible as flashback. -
FIGS. 4A and 4B are proximal views ofPIVC 200 when positioned over a patient'sarm 400 prior to or during insertion ofintroducer needle 211 into the patient's vasculature.FIG. 4A represents a first relative positioning betweencatheter adapter 220 and grip component 210 (or equally betweencatheter adapter 220 and introducer needle 211), whileFIG. 4B represents a second relative positioning betweencatheter adapter 220 andgrip component 210. As described above, in some embodiments,winged grip 222 can be aligned with the bevel of the distal tip ofintroducer needle 211. In such cases, the orientation ofwinged grip 222 shown in bothFIGS. 4A and 4B would result in the bevel facing upward. - Because
grip component 220, in some embodiments, can be rotatable withincatheter 210,winged grip 212 can be repositioned with respect towinged grip 222. Some clinicians may prefer havingwinged grips FIG. 4A , while others may prefer havingwinged grips FIG. 4B .Grip component 220, and more particularlydistal portion 223, can be configured to allow this type of rotation so thatwinged grips - In some embodiments,
grip component 220 and/orcatheter adapter 210 can include one or more structures for limiting the relative rotation between the two components. For example, as shown inFIGS. 4C and 4D ,catheter adapter 210 can includeprotrusions winged grip 222 to limit rotation to 90 degrees. As shown inFIG. 4C ,protrusion 401 b is positioned on an external surface of catheter adapter 210 (e.g. near the proximal opening) so that whenwinged grip 212 is rotated away fromwinged grip 222,protrusion 401 b contacts a bottom surface ofwinged grip 222 stopping rotation once the two components are positioned 180 degrees apart. Similarly, as shown inFIG. 4D ,protrusion 401 a is positioned on an external surface ofcatheter adapter 210 so that whenwinged grip 212 is rotated towardswinged grip 222,protrusion 401 a contacts a top surface ofwinged grip 222 stopping rotation once the two components are positioned 90 degrees apart. -
Protrusions FIGS. 4C and 4D . In other embodiments, one or more protrusions or other structures could be formed ongrip component 220 so as to contact one or more other suitable structures formed oncatheter adapter 210 to limit rotation to a desired amount. - In some embodiments of the present invention, the catheter adapter (
e.g. catheter adapters - In some embodiments of the present invention, the catheter adapter of a PIVC can include a blood-control feature. For example,
FIG. 5 illustrates a cross-sectional view of acatheter adapter 510 that includes a blood-control feature. The blood-control feature is implemented using an elastomeric valve orseptum 516 and anactivator 515.Activator 515 includes alumen 515 a through which an introducer needle can extend.Septum 516 can include aslit 516 a through which the introducer needle as well asactivator 515 can extend. -
FIG. 5 can represent the state of the blood-control feature when a device is not connected tocatheter adapter 510. As shown, when no device is connected,activator 515 is positioned proximally toseptum 516.Septum 516 thereby forms a seal preventing fluid from flowing throughcatheter adapter 510. In some embodiments, including as shown inFIG. 5 , the blood-control feature can include aspring 517 for biasingactivator 515 in the proximal position. - Once a device is connected to
catheter adapter 510, the device can forceactivator 515 into a distal position throughseptum 516 thereby opening a fluid path throughseptum 516. Then, once the device is disconnected fromcatheter adapter 510,spring 517 can forceactivator 515 back into the proximal position again allowingseptum 516 to form a seal. In some embodiments,septum 516 and/oractivator 515 can be configured to naturally bias activator 515 into the proximal position such thatspring 517 would not be required. - Accordingly, embodiments of the present invention provide a non-integrated PIVC having a winged grip and incorporating a blood-control feature. Such PIVCs can be employed to perform intravenous access in a similar manner as with prior art winged infusion sets, but without the many limitations inherent in such prior art sets. Further, because a PIVC in accordance with embodiments of the invention can allow the winged grips to be rotated with respect to one another, a greater degree of customization can be provided to match the preferences of a particular clinician.

FIG. 6A illustrates a top perspective view of aPIVC 600 that is configured in accordance with one or more embodiments of the present invention.PIVC 600 includes acatheter adapter 610 that includes acatheter 611 and forms awinged grip 612.PIVC 600 also includes anintroducer needle 621 that includes agrip component 620. Thegrip component 620 extends to form awinged grip 622.Introducer needle 621 includes anotch 621 a to facilitate the appearance of flashback during insertion. Although not shown,grip component 620 can include a vent for venting gases from withinintroducer needle 621 thereby facilitating blood flow intointroducer needle 621 and throughnotch 621 a.PIVC 600 also includes a blood-control feature 615 similar to the blood control feature described with reference toFIG. 5 . -
FIG. 6B provides a front perspective view ofPIVC 600 whenintroducer needle 621 is contained within catheter adapter 610 (top) and whenintroducer needle 621 has been removed from catheter adapter 610 (bottom). As shown, onceintroducer needle 621 is removed, blood-control feature 615 can form a seal preventing the flow of blood throughcatheter adapter 610. Withintroducer needle 621 removed, a device can be attached to the proximal end ofcatheter adapter 610. The device can be shaped so that, when attached, it activates blood-control feature 615 (e.g. by forcing an activator through a septum or otherwise opening a valve) thereby allowing the flow of fluids throughcatheter adapter 610. - Many variations of the above described examples may also be employed on a PIVC configured in accordance with the present invention. For example, in addition to the shapes of the winged grips shown in the figures, other shapes of winged grips can also be used. In embodiments that employ a winged grip on the catheter adapter, the opposing winged grips need not have symmetrical shapes. For example, one winged grip can be rounded (such as is shown in the figures) while the other may be straight.
- Additionally, in any of the above described examples, a needle shield may be employed to cover the beveled distal tip of the introducer needle once the introducer needle is withdrawn from the catheter. Also, in any of the above described examples, an antimicrobial coating can be applied within the catheter adapter including on any blood-control feature.
- In some embodiments, a PIVC can include an integrated extension set. For example, an extension set can be integrated into the proximal side of the catheter adapter. In such cases, a blood-control feature may not be required since the integrated extension set with adapter can serve as the blood control feature and access port. In this case, a septum in the catheter adapter can provide a non-opening seal once the introducer needle is withdrawn.
- The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
