Abstract

A syringe adapter for holding various sizes of syringes. A syringe includes a tip, a barrel, a plunger, a flange, and a syringe axis extending from the tip to the plunger. An example syringe holder attaches to a fluid delivery system and includes a syringe clamp. The syringe holder holds a syringe stationary in the syringe clamp. The syringe clamp is offset from the fluid delivery system such that the syringe, or connections to the syringe, does not interfere with other components of the fluid delivery system. The syringe holder may include a support bar, which the syringe clamp can slide along. Alternatively, the syringe clamp may be rotatable.

First claim

What is claimed is:

1. A syringe holder for housing a syringe, the syringe holder comprising:
a base comprising an attachment portion and a pivot portion defining a pivot axis, wherein the attachment portion is configured to fixedly attach the base to a main body of an infusion device that includes a mechanism for pumping fluid from the syringe;
a syringe clamp configured to hold a syringe transversely to the pivot axis, wherein the pivot axis extends through the syringe clamp; and
a swivel configured to couple with the base and the syringe clamp, wherein the swivel and syringe clamp are rotatable, relative to the base, about the pivot axis to allow rotation of the syringe relative to the main body of the infusion device,
wherein the swivel comprises a first portion and a second portion defining a cavity between the first portion and the second portion for receiving the syringe clamp,
wherein the syringe clamp further comprises a pad configured to restrict the syringe from sliding and to provide cushion against the syringe clamp for the syringe.

2. The syringe holder of claim 1 , wherein the syringe clamp is configured to hold the syringe perpendicular to the pivot axis.

3. The syringe holder of claim 1 , wherein the syringe clamp comprises a syringe clamp arm configured to move between an open position and a closed position.

4. The syringe holder of claim 3 , wherein the syringe clamp arm is configured to move to the closed position by a spring mechanism.

5. The syringe holder of claim 3 , wherein the syringe clamp arm comprises an outward-projecting portion.

6. The syringe holder of claim 1 , wherein the swivel is configured to freely rotate.

7. The syringe holder of claim 1 , wherein the swivel is configured to rotate between a first angle about the pivot axis and a second angle about the pivot axis.

8. The syringe holder of claim 1 , wherein the pivot portion comprises a first detent mechanism configured to lock the swivel at a first detent angle about the pivot axis.

9. The syringe holder of claim 8 , wherein the first detent mechanism comprises an audible indicator.

10. The syringe holder of claim 1 , wherein the syringe clamp is disposed away from the main body, such that the pivot axis does not extend through the main body.

11. The syringe holder of claim 1 , wherein the pivot axis extends through a space bounded by the syringe clamp on opposing sides of the space.

12. A fluid delivery system comprising:
a fluid delivery device comprising a main body;
a base comprising:
an attachment portion fixedly connected to the main body, and
a pivot portion defining a pivot axis;

a syringe clamp configured to hold a syringe transversely to the pivot axis, wherein the pivot axis extends through the syringe clamp; and
a swivel coupled between the base and the syringe clamp, wherein the swivel and syringe clamp are rotatable, relative to the base, about the pivot axis, to allow rotation of the syringe relative to the main body,
wherein the swivel comprises a first portion and a second portion defining a cavity between the first portion and the second portion for receiving the syringe clamp,
wherein the syringe clamp further comprises a pad configured to restrict the syringe from sliding and to provide cushion against the syringe clamp for the syringe.

13. The fluid delivery system of claim 12 , wherein the syringe clamp comprises a pair of syringe clamp arms configured to move together in a closed position and move apart in an open position.

14. The fluid delivery system of claim 13 , wherein each of the pair of syringe clamp arms is configured to move to the closed position by a respective spring mechanism.

15. The fluid delivery system of claim 12 , wherein the pivot portion comprises a detent mechanism configured to lock the swivel at one of a plurality of detent angles about the pivot axis.

16. The fluid delivery system of claim 12 , wherein the syringe clamp is configured to extend away from the main body.

17. The fluid delivery system of claim 14 , wherein the syringe clamp is configured to extend away from the main body such that a plane of rotation of the syringe clamp is offset from the main body.

18. The fluid delivery system of claim 12 , wherein the syringe clamp is disposed away from the main body, such that the pivot axis does not extend through the main body.

19. A fluid delivery system comprising:
a first fluid delivery device comprising a first main body;
a first base comprising:
a first attachment portion fixedly connected to the first main body, and
a first pivot portion defining a first pivot axis;

a first syringe clamp comprising a first syringe clamp arm configured to hold a first syringe transversely to the first pivot axis, wherein the first pivot axis extends through the first syringe clamp;
a first swivel coupled between the first base and the first syringe clamp, wherein the first swivel and the first syringe clamp are rotatable, relative to the first base, about the first pivot axis, to allow rotation of the first syringe relative to the first main body,
wherein the first swivel comprises a first portion and a second portion defining a first cavity between the first portion and the second portion for receiving the first syringe clamp;
wherein the first syringe clamp further comprises a first pad configured to restrict the first syringe from sliding and to provide cushion against the first syringe clamp for the first syringe;
a second fluid delivery device comprising a second main body;
a second base comprising:
a second attachment portion fixedly connected to the second main body,
and a second pivot portion defining a second pivot axis;

a second syringe clamp comprising a second syringe clamp arm configured to hold a second syringe transversely to the second pivot axis, wherein the second pivot axis extends through the second syringe clamp; and
a second swivel configured to couple with the second base and the second syringe clamp, wherein the second swivel and the second syringe clamp are rotatable, relative to the second base, about the second pivot axis, to allow rotation of the second syringe relative to the second main body and relative to the first syringe,
wherein the second swivel comprises a third portion and a fourth portion defining a second cavity between the third portion and the fourth portion for receiving the second syringe clamp, the second syringe clamp configured to pivot about the second pivot axis with the second swivel,
wherein the second syringe clamp further comprises a second pad configured to restrict the second syringe from sliding and to provide cushion against the second syringe clamp for the second syringe.

20. The fluid delivery system of claim 19 , wherein the first pivot portion comprises a first detent mechanism configured to lock the first swivel at one of a first plurality of detent angles about the first pivot axis, and the second pivot portion comprises a second detent mechanism configured to lock the second swivel at one of a second plurality of detent angles about the second pivot axis.

21. The fluid delivery system of claim 20 , wherein when the first syringe is held by the first syringe clamp at one of the first plurality of detent angles and when the second syringe is held by the second syringe clamp at one of the second plurality of detent angles, an offset space is defined between the first syringe and the second syringe.

22. The fluid delivery system of claim 19 , wherein the
