VASCULAR ACCESS DEVICE ASSEMBLY THAT FACILITATES ONE-HANDED ADVANCEMENT OF A PROBE WITH A SUPPORT MEMBER

Abstract

An IV device assembly may include a lumen that forms a fluidic channel within the IV device assembly. The lumen may be fluidly coupled to a vascular access device (VAD) coupler by a funnel coupler, and an IV device assembly coupler at a proximal end of the lumen. The IV device assembly may also include one or more of the following: a foldable cuff formed coaxially around a first portion of the lumen and mechanically coupled to the funnel coupler, a probe formed along a second portion of the lumen within the foldable cuff and in the VAD coupler, a translation handle that translates the probe from a distal end of the VAD coupler, and a fixed loop formed around the lumen to maintain a position of the IV device assembly relative to the translation handle.

Claims

1. An IV device assembly, comprising: a vascular access device (VAD) coupler at a distal end of the IV device assembly that is mechanically attachable to a VAD, the VAD coupler having a channel formed therethrough; a probe having a length along the IV device assembly; a translation handle mechanically coupled to the probe that translates the probe along the channel formed in the VAD coupler, out of the distal end of the IV device assembly and into the VAD; a support member formed along a length of the probe that mechanically supports the probe as it is translated into the IV device assembly; and a fixed handle formed at a proximal end of the support member that maintains a position of a proximal end of the support member with respect to the translation handle.

2. The device assembly IV of claim 1, further comprising a foldable sleeve formed coaxially around the support member.

3. The IV device assembly of claim 2, wherein the foldable sleeve further comprises a helical spring that creates a space around the probe and tilts the translation handle towards a proximal end of the IV device assembly.

4. The device assembly IV of claim 1, wherein the probe passes through a probe channel formed with respect to the channel formed in the DAV coupler.

5. The device assembly IV of claim 1, further comprising a support member channel formed through the translation handle in which the support member can pass and wherein the support member is keyed to fit within the support member channel and prevents the support member from rotating about a longitudinal axis of the support member.

6. The device assembly IV of claim 1, wherein the support member is a bistable spring and wherein the bistable spring passes within a bistable spring channel formed in the DAV coupler.

7. The device assembly IV of claim 1, wherein: the support member comprises a first sleeve support member arranged coaxially around the probe and a second sleeve support member arranged coaxially around the probe; and the second sleeve support member is dimensioned to slide coaxially within the first sleeve support member as the translation handle is moved along a length of the device assembly IV.

8. The device assembly IV of claim 1, wherein the probe contains a guide needle comprising a porous distal end.

9. The device assembly IV of claim 1, further comprising a funnel coupler mechanically coupled to a proximal end of the DAV coupler, and wherein the funnel coupler comprises a seal preventing fluid from escaping through a proximal end of the funnel coupler.

10. An IV device assembly, comprising: a lumen forming a fluidic channel within the IV device assembly, the lumen fluidly coupled to: a vascular access device (VAD) coupler connectable to a VAD and connected to the lumen by a plug coupler; and an IV device assembly coupler at a proximal end of the lumen; a probe having a length along the IV device assembly; a mechanically coupled translation handle to the probe that translates the probe through a VAD coupler channel formed in the VAD coupler, out of a distal end of the IV device assembly and into the IV device assembly, the translation handle comprising a lumen channel formed therethrough for the lumen to pass through as the translation handle is translated toward the distal end of the IV device assembly;a support member formed along a length of the probe that mechanically supports the probe as it is translated within the IV device assembly; and a fixed handle formed at a proximal end of the support member that maintains a position of a proximal end of the support member relative to the translation handle.

11. The device assembly IV of claim 10, further comprising a support member channel formed in the translation handle.

12. The device assembly IV of claim 11, wherein the support member is keyed to fit within the support member channel and prevent the support member from rotating about a longitudinal axis of the support member.

13. The device IV assembly of claim 10, wherein the support member is a bistable spring which, as the translation handle is moved toward a distal end of the device IV assembly, exits the DAV coupler through a bistable spring channel and coils back on itself.

14. The device assembly IV of claim 10, wherein the support member comprises a helical spring surrounding the length of the probe.

15. An IV device assembly, comprising: a vascular access device (VAD) coupler at a distal end of the IV device assembly that is mechanically attachable to a VAD, the VAD coupler having a channel formed therethrough; a probe having a length along the IV device assembly; a translation handle mechanically coupled to the probe by a probe radius that, as the translation handle is translated, translates the probe through the channel, out of the distal end of the IV device assembly and into the IV device assembly;a support member formed along a length of the probe that mechanically supports the probe as it is translated within the device IV assembly, the support member comprising a tube formed coaxially around the probe, the tube comprising a slot formed along a longitudinal length of the tube, allowing the probe radius to pass through; and a fixed handle formed at a proximal end of the support member that maintains a position of a proximal end of the support member with respect to the translation handle.

16. The IV device assembly of claim 15, further comprising a lumen forming a fluidic channel within the IV device assembly and wherein the lumen is fluidly coupled to the DAV coupler at the distal end of the IV device assembly and a coupler of the IV device assembly at a proximal end of the lumen.

17. The device assembly IV of claim 16, further comprising a foldable sleeve formed coaxially around the probe, tube, and light.

18. The IV device assembly of claim 17, further comprising a support spring formed within the foldable sleeve that creates a space between the foldable sleeve and the probe and tilts the translation handle towards a proximal end of the IV device assembly.

19. The IV device assembly of claim 16, further comprising a blood sample access device fluidly and mechanically coupled to the lumen by the IV device assembly coupler.

20. The device assembly IV of claim 15, wherein the probe contains a guide needle comprising a porous distal end.
