[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 641,599, filed May 2, 2024, entitled “Line Draw Device,” the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure generally relates to pipeline extraction devices, and more specifically, to pipeline extraction devices having various features for supporting the flow tube of the pipeline extraction device and ensuring a secure connection between the pipeline extraction device and other components. Background Technology

[0004] When used in conjunction with indwelling intravenous (IV) catheters, the retraction device may include a displaceable tubing or catheter that is advanced beyond the distal end of the indwelling catheter for blood collection. Typically, as the displaceable catheter is advanced, it may encounter obstruction, causing deflection. Examples of obstruction include friction from seals within the retraction device, tortuous paths within integrated catheters, compression of catheter fittings as they enter the skin, thrombi, fibrin, and valves. This deflection can reduce the ability of the displaceable catheter to extend beyond the distal end of the indwelling catheter, thus limiting its use for blood collection. Some retraction devices include a support tube along a portion of the displaceable catheter to prevent buckling of the displaceable catheter during use. Summary of the Invention

[0054] The following description is provided so as to enable any person skilled in the art to make and use the described embodiments of the application for implementing the present application. Various modifications, equivalents, variations, and alternatives, however, will remain apparent to those skilled in the art. Any and all such modifications, variations, equivalents, and alternatives are intended to fall within the spirit and scope of the present application.

[0055] Hereinafter, for the purpose of description, the terms "upper", "lower", "right", "left", "vertical", "horizontal", "top", "bottom", "lateral", "longitudinal", and derivatives thereof shall relate to the application as oriented in the drawings. However, it is to be understood that the application can assume various alternative variations, unless otherwise specified. It is also to be understood that the specific devices illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the application. Hence, specific dimensions and other physical characteristics related to the embodiments disclosed herein are not to be considered as limiting, unless otherwise specified.

[0056] ​​Referring to FIGS. 1 and 2, a conventional line extractor device 10 includes a housing 12, a hub 14 received within the housing 12, a flow tube 16 defining an internal lumen, connected to and extending distally from the hub 14, a push tube 18 connected to and extending proximally from the hub 14, a push handle 20 at a proximal end of the push tube 18. The housing 12 includes a connector 22 at a distal end of the housing 12 for connecting the line extractor device 10 directly or through an intermediate device or connector to an indwelling peripheral intravenous catheter (PIVC) and a support tube 24 connected to and movable with the flow tube 16. The connector 22 can be integrally formed with the housing 12 or separately formed. The flow tube 16 is movable between a retracted position in which a distal end of the flow tube 16 is received within the housing 12 and an extended position in which the distal end of the flow tube 16 extends beyond the distal end of the housing 12. The line extractor device 10 is configured to couple to and / or otherwise engage an indwelling peripheral intravenous catheter (PIVC) to transfer fluid from a site of a patient (e.g., to aspirate blood) and / or to transfer fluid to a site of a patient (e.g., to infuse a medication or substance). The line extractor device 10 can be one of the line extractor devices shown and described in U.S. Patent No. 11,389,624 and U.S. Patent Application Publication No. 2023 / 0181071, which are hereby incorporated by reference in their entireties.

[0057] One or more problems can arise during use of the line extractor device 10, including: 1) damage to the line extractor device and / or the indwelling catheter as the support tube (typically a metal tube) is advanced into the indwelling catheter or component; 2) loss of flexibility of the indwelling catheter as the support tube is advanced, or insufficient flexibility of the system or component, which can result in less than ideal blood draw technique using an inverted collection tube, which can inhibit proper mixing of the blood with additives in the collection tube, inability to see fill level, and also result in dislodgement of the indwelling catheter or excessive site manipulation of the indwelling catheter; 3) the line extractor device 10 easily disconnects components of the indwelling catheter or related components during connection of the line extractor device 10 to the indwelling catheter or related components; 4) inadvertent disconnection of the connector 22 from a needleless connector or indwelling catheter; 5) insufficient extension or reach of the flow tube 16 to achieve optimal blood draw success rates; 6) damage can occur from blunt cannula or other features of the connector 22 contacting the needleless connector or indwelling catheter; and 7) the line extractor device 10 is prone to premature and inadvertent retraction during the line extraction process.

[0058] A support tube 24 is provided to reduce the likelihood of kinking during advancement of the flow tube 16 through an indwelling catheter. The flow tube 16 is connected to and extends distally from the support tube 24, and a portion of the flow tube 16 can be positioned inside at least a portion of the support tube. A discontinuity is created at the transition between the support tube 24 and the flow tube 16, which can result in a risk of kinking, kinking, damage, or severing of the flow tube 16 at this site, as the support tube 24 can be a thin-walled metal tube that can easily damage the flow tube 16 or other polymeric system components at one end. These risks and issues are exacerbated if used with catheters that include integrated extension sets and / or fluid path centerline angle changes, such as the Nexiva integrated catheter commercially available from Becton, Dickinson and Company.

[0059] Referring again to FIG. 2, the flow tube 16 and support tube 24 arrangement as described above can introduce problems as they are further advanced through a series of vascular access devices and device types. The flow tube 16 and support tube 24 arrangement can result in kinking and kinking of the flow tube 16, permanent bending and deformation of the support tube 24, cutting or separation of a portion of the flow tube 16 from the tubing set assembly, stripping and damage to components of the indwelling catheter or needleless connector, including any plastic components that the support tube 24 contacts, and the catheter tubing, puncturing of the catheter or extension set tubing, and loss of the required flexibility of the flexible member of the catheter system when used with certain vascular access devices or indwelling catheters.

[0060] Referring to FIGS. 3-5 Figure 6 , a schematic view of the line extractor device 10 in combination with an integrated catheter 30, such as the Nexiva integrated catheter commercially available from Becton, Dickinson and Company, is shown. As shown in FIG. 3, if the support tube 24 is advanced too far, the support tube 24 can collide with the catheter adapter or internal structure, which can result in kinking or damage to the flow tube 16. As shown in FIGS. 4 and 5, the support tube 24 can be positioned within or outside of the flexible extension tube portion of the integrated catheter 30, which can damage and limit the flexibility of the integrated catheter 30. As shown in FIG. 6, the support tube 24 can damage the catheter adapter or wedge region of the integrated catheter 30, the catheter adapter port ramp, the flexible extension tube portion of the integrated catheter 30, or the inlet of the needleless connector. Figure 4 and Figure 5 As shown in FIGS. 4 and 5, the support tube 24 can be positioned within or outside of the flexible extension tube portion of the integrated catheter 30, which can damage and limit the flexibility of the integrated catheter 30. As shown in FIG. 6, the support tube 24 can damage the catheter adapter or wedge region of the integrated catheter 30, the catheter adapter port ramp, the flexible extension tube portion of the integrated catheter 30, or the inlet of the needleless connector. Figure 6

[0061] Referring to Figure 7 to Figure 12 ​According to one aspect or embodiment, various concepts are presented that include one or more features to ensure that the distal edge of the support tube 24 remains close to any flexible portions of the fluid path and / or any portions of the fluid path having a centerline and a characteristic angular change that can cause the support tube 24 to contact and damage the integrated catheter 30 or related components.

[0062] Referring to Figure 8 to Figure 12 According to one aspect or embodiment, a line extractor 100 similar to the line extractor 10 is shown. However, the line extractor 100 includes a collapsible support 102 positioned within the housing 12 through which a portion of the flow tube 16 extends, where the collapsible support 102 has a first length when the flow tube 16 is in the retracted position and a second length when the flow tube 16 is in the extended position. The first length is greater than the second length.

[0063] As shown in Figure 8 and Figure 9 , in one aspect or embodiment, the collapsible support 102 includes an accordion fold to allow the collapsible support 102 to collapse from an expanded state ( Figure 8 ) to a collapsed state ( Figure 9 ) as the flow tube 16 and hub 14 are advanced. The collapsible support 102 can be formed of a resilient material and configured to collapse due to the material and / or shape of the collapsible support 102. The line extractor 100 includes a support tube 24 as discussed above in connection with the line extractor 10. However, the support tube 24 of the line extractor 100 is shortened such that the distal end of the support tube 24 does not extend beyond the needleless connector of the integrated catheter 30. The collapsible support 102 does not move with the flow tube 16 and support tube 24. In some aspects or embodiments, the distal end of the collapsible support 102 is connected to the housing 12 and the remainder of the collapsible support 102 is free to move relative to the housing 12. The collapsible support 102 is configured to provide additional support to the flow tube 16 during movement of the flow tube 16 from the retracted position to the extended position. As the advancement handle 20 and / or the advancement tube 18 are moved distally, the flow tube 16 moves relative to the collapsible support 102 while engaging at least a portion of the collapsible support 102 to prevent kinking or bending during advancement of the flow tube 16 through the integrated catheter 30 and the vein of the patient. In some aspects or embodiments, the collapsible support 102 is in continuous contact with the flow tube 16 or the support tube 24. In some aspects or embodiments, the collapsible support 102 is spaced apart from the flow tube and only contacts the flow tube 16 during bending of the flow tube 16 from the longitudinal axis of the line extractor 100. As Figure 9As shown, when the flow tube 16 is switched from the retracted position to the extended position to allow the collapsible support 102 to collapse, the hub 14 engages with the collapsible support 102, which allows the flow tube 16 to extend fully without adding additional length to the housing 12.

[0064] The shortened support tube 24 allows a portion of the flow tube 16 to be unsupported without the collapsible support 102. Therefore, the shortened support tube 24 and the collapsible support 102 allow the flow tube 16 to be supported while ensuring that the distal edge of the support tube 24 remains close to any flexible portion of the fluid path and / or any portion of the fluid path with a centerline and characteristic angular variation, which could cause the support tube 24 to contact and damage the integrated conduit 30 or related components, as described above.

[0065] like Figure 10 As shown, in some aspects or embodiments, the tubing extraction device 100 includes a locking member 110 connected to the housing 12, wherein the locking member 110 is configured to engage the hub 14 when the tubing 16 is in the extended position. In one aspect or embodiment, the locking member 110 is a push-button lock or pawl that engages with one or more jacks or recesses defined by the hub 14 or the housing 12. In one aspect or embodiment, the locking member 110 engages with a circumferential recess defined by the hub 14. In one aspect or embodiment, the locking member 110 is positioned on the hub 14 and engages with the housing 12. The locking member 110 ensures that compressive forces from the collapsible support 102 do not push the tubing 16 out of the vein during blood collection. In one aspect or embodiment, the locking member 110 is provided separately (without the collapsible support 102) to prevent accidental retraction of the tubing 16.

[0066] like Figure 11 and Figure 12 As shown, in one aspect or embodiment, the collapsible support 102 includes a telescopic section to allow the collapsible support 102 to extend from its deployed state when the flow tube 16 and hub 14 are advanced. Figure 11 ) collapsed to a collapsed state ( Figure 12 In some aspects or embodiments, the retractable section is formed of metal or plastic.

[0067] refer to Figure 13 and Figure 14According to an aspect or embodiment, a pipeline extraction device 200 similar to the pipeline extraction device 10 is shown. However, the pipeline extraction device 200 includes a flexible support tube 202. In some aspects or embodiments, the support tube 202 is formed of a semi-rigid but flexible material. In some aspects or embodiments, the support tube 202 is formed of polyimide, polyurethane, nitinol, or a combination thereof. In some aspects or embodiments, the support tube 202 is a polymeric sleeve or a tapered flow tube 16. The flexible support tube 202 is more flexible than a thin-walled metal tube, such as the support tube 24 described above. As shown in Figure 14 one aspect or embodiment, the support tube 202 includes a wire coil 204. The wire coil 204 can have a constant or variable winding. In one aspect or embodiment, the wire coil 204 includes a tight winding on a proximal length and a loose winding on a distal end to provide support for the flow tube 16 while the wire coil 204 is flexible to support the flow tube 16 through angle changes during advancement of the flow tube 16. The wire coil 204 adds flexibility during advancement of the flow tube 16, but can also be compressed if an elbow or catch is encountered to allow continued advancement of the flow tube 16, even though the distal end of the wire coil 204 is not continuing to advance.

[0068] Referring to Figure 15 to Figure 20 , according to various aspects or embodiments, various concepts for a transition between the support tube 24 and the flow tube 16 are shown that are configured to reduce damage to the indwelling catheter or related components. In some aspects or embodiments, the transition between the support tube 24 and the flow tube 16 includes an overmold Figure 15 ), a tapered segment or portion Figure 16 and Figure 17 ), a chamfer Figure 18 ), and / or a radius Figure 19 . As shown in Figure 20 one aspect or embodiment, the transition between the support tube 24 and the flow tube 16 includes an asymmetric end of the support tube 24.

[0069] Referring to Figure 21 , according to an aspect or embodiment, a pipeline extraction device 300 similar to the pipeline extraction device 10 is shown. However, the pipeline extraction device 300 includes a flexible housing 302. In some aspects or embodiments, the flexible housing 302 is flexible due to the material and / or shape of the flexible housing 302. In some aspects or embodiments, the flexible housing 302 includes one or more flexible sections 304, rather than the entire flexible housing 302 being flexible; or in addition to the entire flexible housing 302 being flexible, the flexible housing 302 includes one or more flexible sections 304.

[0070] Referring to Figure 22 to Figure 26According to an aspect or embodiment, a line extractor 400 similar to line extractor 10 is shown. However, line extractor 400 includes an extension tube 402 that is connected to the push handle 20 ( Figure 22 ) or to the hub 14 ( Figure 23 to Figure 26 ). As shown in Figure 23 to Figure 26 , in some aspects or embodiments, line extractor 400 includes a push member 404 as an actuator (rather than providing the push tube 18 as an actuator) to move the flow tube 16 between the retracted and extended positions. The extension tube 402 can be aligned with the longitudinal axis of the housing 12 of the line extractor 400 or can be at an angle or non-parallel to the longitudinal axis of the housing 12. As shown in Figure 23 and Figure 24 , the extension tube 402 remains flexible to ensure optimal blood extraction when the push member 404 is moved from the retracted position ( Figure 23 ) to the extended position ( Figure 24 ). As shown in Figure 25 and Figure 26 , in one aspect or embodiment, the push member 404 includes a handle portion 406 that is configured to move along the housing 12 as the flow tube 16 is moved between the retracted and extended positions, with the push member 404 extending proximally from the hub 14 and distally after a transition portion 408.

[0071] Referring to Figure 27 , in one aspect or embodiment, the connector 450, similar to the connector 22 of the line extractor 10, includes one or more features to inhibit the straight catheter from disconnecting from the needleless connector when the line extractor 10 is attached and while the rotating nut of the needleless connector is clamped during attachment of the line extractor 10. These features can include: adjusting the Luer Lok thread pitch angle, as shown in Figure 27 ; adding friction bumps or other friction generating features on the rotating nut of the needleless connector or the blunt cannula luer of the line extractor 10; changing the material to obtain differential attachment torque; applying silicone on the threads of the blunt cannula and / or the connector 22; and / or reducing the height or outer diameter of the luer to reduce compression on the needleless connector.

[0072] Referring to Figure 28 to Figure 30In one aspect or embodiment, the connector 500, similar to the connector 22 of the line extractor device 10, also includes a movable locking member 502. The movable locking member 502 is configured to engage the corresponding component 504, such as a female luer, when received by the male luer lock, to lock the corresponding component 504 to the housing 12.
