Abstract

An exemplary infusion set includes a tubing, a first connector, and a second connector. The first connector connects a first terminus of the tubing to an exit port of an infusion pump, providing fluid communication between fluid being conveyed by the infusion pump and the tubing. The second connector connects a second terminus of the tubing to a delivery module, providing fluid communication between the tubing and the delivery module. Full engagement of the first connector and the exit port of the infusion pump actuates operation of the infusion pump.

Claims

1. An infusion set comprising:

tubing;

a first connector, which first connector connects a first terminus of said tubing to an exit port of an infusion pump, providing fluid communication between fluid being conveyed by said infusion pump and said tubing; and

a second connector which connects a second terminus of said tubing to a delivery module, providing fluid communication between said tubing and said delivery module;

wherein full engagement of said first connector and said exit port of said infusion pump actuates operation of said infusion pump.

2. The infusion set of claim 1, wherein said first connector connects said first terminus of said tubing to said exit port of said infusion pump via a water-tight sealed mechanism.

3. The infusion set of claim 1, wherein said second connector connects said second terminus of said tubing to said delivery module via a water-tight sealed mechanism.

4. The infusion set of claim 1, wherein said first connector comprises an actuator element, which actuates operation of the infusion pump upon full connection of said first connector with said exit port of said infusion pump without requiring additional action from the infusion pump user.

5. The infusion set of claim 4, wherein said actuator element is a cantilever.

6. The infusion set of claim 4, wherein said actuator element operates a mechanical switch to initiate operation of said infusion pump.

7. The infusion set of claim 4, wherein said actuator element operates a magnetic switch to initiate operation of said infusion pump.

8. The infusion set of claim 4, wherein said actuator element prevents operation of said infusion pump if said first connector subsequently becomes fully or partially disconnected with said exit port of said infusion pump.

9. The infusion set of claim 4, wherein said actuator element actuates operation of said infusion pump even if said first connector subsequently becomes fully or partially disconnected with said exit port of said infusion pump.

10. The infusion set of claim 1, wherein said tubing has a narrow bore with a diameter from about 40 to about 150 microns, and is chosen such that said diameter provides for optimal back pressure in an infusion pump connected to said infusion set.

11. The infusion set of claim 1, wherein said tubing has a narrow bore with a diameter from about 60 to about 100 microns, and is chosen such that said diameter provides for optimal back pressure in an infusion pump connected to said infusion set.

12. The infusion set of claim 10, wherein said tubing length is chosen such that short priming durations for said pump and low volume or flow rates are accommodated.

13. The infusion set of claim 10, wherein said tubing diameter is chosen such that a siphoning effect is reduced or eliminated.

14. The infusion set of claim 10, wherein said infusion set prevents egress of air bubbles from occluding or blocking the fluid flow path.

15. An infusion set comprising:

tubing comprising;

at least a first tubing length having a first inner diameter,

a second tubing length, which second tubing length has a second inner diameter which is larger than that of said first inner diameter

wherein said first tubing length and said second tubing length are connected to each other in a water-tight sealed manner;

a first connector which connects a first terminus of said tubing to an exit port of an infusion pump in a water-tight sealed manner; and

a second connector which connects a second terminus of said tubing to a delivery module;

wherein a fluid being conveyed by said infusion pump is in fluid communication with said tubing and said delivery module.

16. The infusion set of claim 15, wherein said first tubing length is chosen such that said first inner diameter provides for optimal back pressure in an infusion pump connected to said infusion set.

17. The infusion set of claim 15, wherein said first tubing length is chosen such that short priming durations for said pump and low volume or flow rates are accommodated.

18. The infusion set of claim 15, wherein said first tubing diameter is chosen such that a siphoning effect is reduced or eliminated.

19. The infusion set of claim 15, wherein said first tubing inner diameter ranges from about 20 to about 60 microns in diameter.

20. The infusion set of claim 15, wherein said infusion set prevents egress of air bubbles from occluding or blocking a fluid flow path in said infusion set.

21. The infusion set of claim 15, wherein said first connector comprises an actuator element, which actuates operation of the infusion pump upon full connection of said first connector with said exit port of said infusion pump without requiring additional action from the infusion pump user.

22. The infusion set of claim 21, wherein said actuator element is a cantilever.

23. The infusion set of claim 21, wherein said actuator element operates a mechanical switch to initiate operation of said infusion pump.

24. The infusion set of claim 21, wherein said actuator element operates a magnetic switch to initiate operation of said infusion pump.

25. The infusion set of claim 21, wherein said actuator element prevents operation of said infusion pump if said first connector subsequently becomes fully or partially disconnected with said exit port of said infusion pump.

26. The infusion set of claim 21, wherein said actuator element actuates operation of said infusion pump even if said first connector subsequently becomes fully or partially disconnected with said exit port of said infusion pump.
