Abstract

A delivery adapter which may be used as an interface between a syringe and a catheter hub is described.

First claim

What is claimed is:

1 . An adapter comprising:
a first connector adapted for connection to a syringe; a tube extending from the first connector; a second connector adapted for connection to a catheter hub, the second connector having a lumen accommodating the tube; wherein the second connector has a first configuration where it is freely movable over the tube and a second configuration where it is fixed in place over the tube to control how much of the tube extends distally beyond the second connector.

2 . The adapter of claim 1 wherein the second connector includes a cap piece releasably engaged with a base piece.

3 . The adapter of claim 2 wherein the cap piece is rotationally engaged with the base piece.

4 . The adapter of claim 1 wherein said tube includes projecting elements.

5 . The adapter of claim 4 wherein the projecting elements are angled tapers.

6 . The adapter of claim 4 wherein the second connector includes a seal which engages with the tube's projecting elements thereby fixing the second connector in place.

7 . The adapter of claim 6 wherein the seal is a flexible annular cylinder.

8 . An adapter comprising:
a first connector adapted for connection to a syringe; a tube extending from the first connector; a second connector adapted for connection to a catheter hub, the second connector having a lumen accommodating the tube; a seal disposed within the second connector; wherein the seal has a first configuration where the seal is freely movable over the tube and a second configuration where the seal is fixed to the tube thereby controlling how much of the tube extends distally beyond the second connector.

9 . The adapter of claim 8 wherein the second connector includes a cap piece releasably engaged with a base piece.

10 . The adapter of claim 9 wherein the cap piece is rotationally engaged with the base piece.

11 . The adapter of claim 8 wherein the seal is a flexible annular cylinder.

12 . The adapter of claim 8 wherein the seal is a silicone cylindrical element with a lumen therein.

13 . The adapter of claim 8 wherein said tube includes projecting elements.

14 . The adapter of claim 13 wherein the projecting elements are angled tapers.

15 . An adapter comprising:
a first connector adapted for connection to a syringe; a tube extending from the first connector; a second connector adapted for connection to a catheter hub, the second connector having a lumen accommodating the tube, the second connector further including a cap piece releasably fixed to a base piece; wherein the second connector's position over the tube is fixed when the cap piece is fixed to the base piece, thereby controlling how much of the tube extends distally beyond the second connector.

16 . The adapter of claim 15 wherein the cap piece is rotationally engaged with the base piece.

17 . The adapter of claim 15 wherein the tube includes projecting elements.

18 . The adapter of claim 17 wherein the projecting elements are angled tapers.

19 . The adapter of claim 17 wherein the second connector includes a seal which engages with the tube's projecting elements thereby fixing the second connector in place.

20 . The adapter of claim 19 wherein the seal is a flexible annular cylinder.
