Abstract

A venous access device is generally discussed herein with particular discussions extended to port access device having a protective clip. The port access device includes a needle hub having a needle extending therefrom and a catheter hub having a catheter tube extending therefrom with the needle positioned inside the tube in a ready to use position. A tip protector is positioned inside a clip housing, which is positioned in between the catheter hub and the needle hub.

Claims

1. An access port device comprising a catheter hub comprising a catheter tube extending therefrom, a needle hub comprising a needle having a needle tip extending through the catheter tube, and a housing disposed between the needle hub and the catheter hub;

the housing being engaged to the catheter hub so that when the needle hub is rotated relative to the housing, the housing remains fixed to the catheter hub.

2. The access port device of claim 1, wherein the housing comprises a plurality of spaced apart teeth.

3. The access port device of claim 1, wherein the housing is threadedly engaged to the catheter hub.

4. The access port device of claim 1, wherein the needle is at least one of a Huber needle, a Trocar needle, and a pencil point needle.

5. The access port device of claim 1, whether a distal end of the catheter tube seals against the needle.

6. The access port device of claim 1, where the needle tip moves proximally of a distal opening of the catheter tube when the needle hub is rotated relative to the catheter hub.

7. The access port device of claim 6, further comprising an annular space between the catheter tube and the needle.

8. The access port device of claim 1, further comprising a tip protector for covering the needle tip.

9. The access port device of claim 8, wherein the tip protector comprises a proximal wall have a first wall surface and an opposing second wall surface.

10. The access port device of claim 1, wherein the catheter hub comprises a septum.

23. The access port device of claim 1, wherein the catheter hub comprises at least one wing.

11. An access port device comprising a catheter hub comprising a catheter tube extending therefrom, a needle hub comprising a needle having a needle tip extending through the catheter tube and beyond a distal end of the catheter tube, a housing disposed between the needle hub and the catheter hub, and a tip protector for covering the needle tip positioned inside a cavity defined by the housing;

wherein the housing is threadedly engaged to the needle hub.

12. The access port device of claim 11, wherein the housing comprises a plurality of spaced apart teeth.

13. The access port device of claim 11, wherein the needle is at least one of a Huber needle, a Trocar needle, and a pencil point needle.

14. The access port device of claim 11, wherein the distal end of the catheter tube seals against the needle.

15. The access port device of claim 11, wherein needle tip moves proximally of the distal end of the catheter tube when the needle hub is rotated relative to the catheter hub.

16. The access port device of claim 11, further comprising a septum positioned inside the catheter hub.

24. The access port device of claim 11, wherein the catheter hub comprises at least one wing.

17. An access port device comprising a catheter hub comprising a catheter tube extending therefrom, a needle hub comprising a needle having a needle tip extending through the catheter tube and beyond a distal opening of the catheter tube, a housing disposed between the needle hub and the catheter hub, and a tip protector for covering the needle tip positioned inside a cavity defined by the housing;

wherein the catheter hub further comprises a flow chamber in fluid communication with the catheter tube.

18. The access port device of claim 17, wherein the catheter hub incorporates a septum.

19. The access port device of claim 18, wherein the needle passes through the septum.

20. The access port device of claim 17, where the housing is threadedly engaged to the needle hub.

21. The access port device of claim 17, where the needle tip moves proximally of the distal opening when the needle hub is rotated relative to the catheter hub.

22. The access port device of claim 21, further comprising an annular flow space between the needle and the catheter tube.

25. The access port device of claim 17, wherein the catheter hub comprises at least one wing.
