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, wherein;

the tubing comprises a first tubing length having a narrow bore with a first inner diameter from 40 to 150 microns,

the tubing comprises a second tubing length having a second inner diameter, and

the second inner diameter is larger than that of the first inner diameter;

a first connector which comprises a lateral extension and which 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 comprises engagement of said lateral extension of said first connector with an actuator element of said infusion pump, and actuates operation of said infusion pump to deliver the fluid from said infusion pump to said exit port, and

the second tubing length is nearer to the second connector than the first tubing length is to the second connector.

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 actuator element 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 a user of the infusion pump.

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 the first inner diameter is within a range from 60 to 100 microns.

11. The infusion set of claim 1, wherein the first inner diameter is within a range from 70 to 95 microns.

12. The infusion set of claim 1, wherein the full engagement of said first connector and said exit port of said infusion pump comprises magnetically actuating operation of said infusion pump to deliver the fluid from said infusion pump to said exit port.

13. An infusion set comprising:

tubing, wherein;

the tubing comprises a first tubing length having a narrow bore with a first inner diameter from 40 to 150 microns,

the tubing comprises a second tubing length having a second inner diameter, and

the second inner diameter is larger than that of the first inner diameter;

a first connector which 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 to deliver the fluid from said infusion pump to said exit port, and

the second tubing length is nearer to the second connector than the first tubing length is to the second connector.

14. The infusion set of claim 13, wherein the first inner diameter is from 60 to 100 microns.

15. The infusion set of claim 13, wherein said tubing has an overall length within a range from 10 micrometers to 30 centimeters.

16. The infusion set of claim 13, wherein the first inner diameter is from 70 to 95 microns.

17. The infusion set of claim 13, wherein said infusion set prevents egress of air bubbles from occluding or blocking a fluid flow path.
