Abstract

Provided here is a tubing connector having a body that has a first end, having a first opening and a second end having a second opening. A passageway extends through the body between the first opening and the second opening. A side opening including a first side wall, and opposing second side wall and a latch catch disposed between the first and second side walls extends from the passageway through the body. The body also has a cannula extending into the passageway from the first end toward the second end. The side opening is disposed between the cannula and the second end. The connector also has a clamping member, having a first clamping end that is hingedly connected to the body and a second clamping end that is adapted to releasably engage the latch catch. A clamp portion is disposed between the first clamping end and the second clamping end.

Claims

1. A tubing connector comprising:

a body having a first end having a first opening, a second end having a second opening, a passageway extending through the body between the first opening and the second opening, and a side opening extending from the passageway through the body, wherein the side opening includes a first side wall, an opposing second sidewall, and a latch catch disposed between the first side wall and the second side wall;

a cannula extending into the passageway from the first end toward the second end, wherein the side opening is disposed between the cannula and the second end; and

a clamping member having a first clamping end hingedly connected to the body, a second clamping end having a latch adapted to releasably engage the latch catch, and a clamp portion extending between the first clamping end and the second clamping end.

2. The connector according to claim 1, wherein the first clamping end is hingedly connected to each of the first side wall and the second side wall.

3. The connector according to claim 1, wherein the cannula is releasably connected to the first end of the body.

4. The connector according to claim 3, wherein the cannula is threadably connected to the first end of the body

5. The connector according to claim 1, wherein the body further comprises a proximal portion and a distal portion, wherein the proximal portion includes the cannula and wherein the distal portion includes the side opening, and wherein the proximal portion is releasably connected to the distal portion.

6. The connector according to claim 5, wherein the proximal portion further comprises a proximal end having a connection for releasably connecting an external device to the connector.

7. The connector according to claim 6, wherein the external device is a cap.

8. The connector according to claim 7, wherein the external device is a hemodialysis machine.

9. The connector according to claim 1, further comprising a sliding lock, slidably disposed about the body.

10. A tubing connector comprising:

a first end,

a second end,

a longitudinal axis extending therethrough between the first end and the second end;

a tubular body extending between the first end and the second end;

a longitudinal passageway extending along the longitudinal axis between the first end and the second end, wherein the longitudinal passageway is defined by the tubular body;

a side opening extending from the longitudinal passageway through the tubular body, in a direction that is generally perpendicular to the longitudinal axis, wherein the side opening is defined by a first side wall and a second side wall; and

a clamping member disposed within the side opening, wherein the clamping member is disposable in an open position and a closed position, wherein the clamping member is pivotable about an axis that is generally parallel to the longitudinal axis.

11. The tubing connector according to claim 10, wherein the clamping member is hingedly disposed within the side opening.

12. The tubing connector according to claim 10, further comprising a latch catch disposed proximate to the side opening.

13. The tubing connector according to claim 12, wherein the clamping member further comprises a latch, wherein the latch is releasably engageable with the latch catch.

14. The connector according to claim 10, further comprising a sliding lock, slidably disposed about the body.

15. The connector according to claim 10, wherein the tubing connector further comprises a proximal portion and a distal portion, wherein the distal portion includes the side opening, and wherein the proximal portion is releasably connected to the distal portion.

16. The connector according to claim 15, wherein the proximal portion further comprises a proximal end having a connection for releasably connecting an external device to the connector.

17. The connector according to claim 16, wherein the external device is a cap.

18. The connector according to claim 17, wherein the external device is a hemodialysis machine.

19. A catheter assembly comprising:

a tubing connector including;

a body having a first end having a first opening, a second end having a second opening, a passageway extending through the body between the first opening and the second opening, and a side opening extending from the passageway through the body, wherein the side opening includes a first side wall, an opposing second sidewall, and a latch catch disposed between the first side wall and the second side wall;

a cannula extending into the passageway from the first end toward the second end, wherein the side opening is disposed between the cannula and the second end; and

a clamping member having a first clamping end hingedly connected to the body, a second clamping end having a latch adapted to releasably engage the latch catch, and a clamp portion disposed between the first clamping end and the second clamping end; and

a catheter lumen having a proximal end in fluid communication with the cannula and extending from the second end of the body,

wherein the clamping member is adapted to clamp the catheter lumen to releasably restrict fluid flow in the catheter lumen between the cannula and the second end of the body.

20. The connector according to claim 19, wherein the first clamping end is hingedly connected to each of the first side wall and the second side wall.

21. The connector according to claim 19, wherein the first end of the body is releasably connected to the second end of the body;

and wherein the first end of the body comprises the cannula.

22. The connector according to claim 21, wherein the first end of the body is threadably connected to the second end of the body.

23. The connector according to claim 19, wherein the first end further comprises a proximal end having a connection for releasably connecting an external device to the connector.

24. The connector according to claim 23, wherein the external device is a cap.

25. The connector according to claim 23, wherein the external device is a hemodialysis machine.

26. The connector according to claim 19, further comprising a sliding lock, slidably disposed about the body.
