Abstract

A transfer device for filing a fluid reservoir of a fluid infusion device with a fluid is provided. The transfer device comprises a first end to couple to a source of the fluid, and a second end to couple to a pressurizing device. The transfer device also comprises a body interconnecting the first end and the second end, and having an end to couple to the fluid reservoir. The body defining at least one fluid flow path between the source of the fluid, the pressurizing device and the fluid reservoir to enable the filling of the fluid reservoir with the fluid

Claims

1. A transfer device for filing a fluid reservoir of a fluid infusion device with a fluid, the transfer device comprising:

a first end to couple to a source of the fluid;

a second end to couple to a pressurizing device; and

a body interconnecting the first end and the second end and having an end to couple to the fluid reservoir, the body defining at least one fluid flow path between the source of the fluid, the pressurizing device and the fluid reservoir to enable the filling of the fluid reservoir with the fluid.

2. The transfer device of claim 1, wherein the first end includes at least one projection that extends upwardly from a base, and the at least one projection is to couple the source of the fluid to the transfer device.

3. The transfer device of claim 2, wherein the base includes a protrusion and the first end includes a piercing member coupled to the protrusion, and the piercing member establishes a fluid flow path from the source of the fluid into the transfer device.

4. The transfer device of claim 1, wherein the body further comprises a first branch, a second branch and a third branch, and the first branch is coupled to the first end, the second branch is coupled to the second end and the third branch defines the end.

5. The transfer device of claim 4, wherein the first branch defines a passage, the second branch defines a second passage and the third branch defines a third passage, with the passage, second passage and third passage defining the at least one fluid flow path between the source of the fluid, the pressurizing device and the fluid reservoir.

6. The transfer device of claim 5, wherein a valve is coupled to the passage of the first branch to restrict the flow of fluid into the passage.

7. The transfer device of claim 6, wherein the valve is a one-way valve that opens upon the application of a negative pressure to the second end of the transfer device.

8. The transfer device of claim 5, wherein a filter is coupled to the second passage to restrict the flow of fluid into the second passage.

9. The transfer device of claim 8, wherein the filter is a hydrophilic filter and restricts the flow of air into the second passage.

10. A system for filing a fluid reservoir of a fluid infusion device with a fluid, comprising:

the fluid reservoir including a port for receipt of the fluid; and

a transfer device having a body with an end coupleable to the port of the fluid reservoir, a first end to couple to a source of the fluid and a second end to couple to a pressurizing device,

wherein the body defines at least one fluid flow path between the source of the fluid, the pressurizing device and the fluid reservoir to enable the filling of the fluid reservoir with the fluid.

11. The system of claim 10, wherein the first end includes two projections that each extend upwardly from a base, and the projections are spaced apart to couple the source of the fluid to the transfer device.

12. The system of claim 11, wherein the base includes a protrusion and the first end includes a piercing member coupled to the protrusion, and the piercing member establishes a fluid flow path from the source of the fluid into the transfer device.

13. The system of claim 10, wherein the body further comprises a first branch coupled to the first end, a second branch coupled to the second end and a third branch that defines the end.

14. The system of claim 13, wherein the first branch defines a passage, the second branch defines a second passage and the third branch defines a third passage, with the passage, second passage and third passage defining the at least one fluid flow path between the source of the fluid, the pressurizing device and the fluid reservoir.

15. The system of claim 13, wherein the first branch and the second branch are parallel to a longitudinal axis of the transfer device, and the third branch is transverse to the longitudinal axis of the transfer device.

16. The system of claim 14, wherein a valve is coupled to the passage of the first branch to restrict the flow of fluid into the transfer device.

17. The system of claim 14, wherein a filter is coupled to the second passage to restrict the flow of air into the transfer device.

18. A system for filing a fluid reservoir of a fluid infusion device with a fluid, comprising:

a source of pressure;

the fluid reservoir including a port for receipt of the fluid; and

a transfer device including a body having a first branch, a second branch and a third branch, the first branch to couple to a source of the fluid, the second branch coupleable to the source of pressure and the third branch couplable to the fluid reservoir, with a valve disposed in the first branch, the valve responsive to the source of pressure to permit the fluid to flow into the body and the body defines at least one fluid flow path between the source of the fluid, the pressurizing device and the fluid reservoir to enable the filling of the fluid reservoir with the fluid.

19. The system of claim 18, wherein the valve is a one-way valve that opens upon the application of a negative pressure to the second branch of the body by the source of pressure.

20. The system of claim 18, wherein a hydrophilic filter is coupled to the second branch to restrict the flow of air into the body.
