Abstract

A disposable patch pump may be provided with a filling adapter, to ensure filling by an authorized user. The adapter mates with the pump and a source of medicament, such as an insulin vial, to prevent filling the pump directly with a conventional syringe. The adapter and/or pump filling port may be configured with a frangible element, to limit the system to single use.

Claims

1. A patch pump system comprising:

a patch pump device comprising;

a filling port, and

a shutter proximate the filling port movable about a pin between a closed position and an open position and adapted to prevent access to the filling port in the closed position, wherein the shutter comprises;

a central portion and at least one wing portion extending therefrom, wherein the at least one wing portion is configured to prevent access to the filling port in the closed position, and

an opening disposed in the central portion, wherein the opening is configured to receive the pin therein; and

a filling adapter configured to be locked to the filling port and to move the shutter from the closed position to the open position, wherein the filling adapter comprises;

a first portion and a second portion,

a rim disposed about the second portion, and

a protrusion disposed on the rim, wherein the protrusion is configured to engage the opening of the central portion of the shutter to rotate the shutter about the pin from the closed position to the open position upon rotation of the filling adapter.

2. The patch pump system of claim 1, wherein the filling port comprises a septum.

3. The patch pump system of claim 1, wherein the filling port is accessible from a user contact side of the patch pump device.

4. The patch pump system of claim 1, wherein the shutter is accessible from a user contact side of the patch pump device.

5. The patch pump system of claim 1, wherein the shutter is disposed within the patch pump device.

6. The patch pump system of claim 1, wherein the shutter is disposed within the filling port.

7. The patch pump system of claim 1, wherein the shutter defines a shutter opening.

8. The patch pump system of claim 1, wherein the shutter is a valve.

9. The patch pump system of claim 1, wherein the patch pump device defines a device opening for coupling the filling adapter to the filling port and enabling controlled rotation of the shutter.

10. The patch pump system of claim 1, wherein the filling adapter comprises a hollow needle.

11. The patch pump system of claim 1, wherein a first end of the filling adapter is adapted to mate with a medicament container.

12. The patch pump system of claim 1, further comprising a socket adapted to receive the filling adapter.

13. The patch pump system of claim 1, wherein the second portion is coaxially arranged with respect to the first portion, and wherein the first portion is slidingly displaceable within the second portion.

14. The patch pump system of claim 13, wherein the filling adapter comprises:

a shoulder disposed about the first portion; and

an annular ring disposed about the second portion, wherein the shoulder is configured to abut the annular ring.

15. The patch pump system of claim 1, wherein the filling adapter comprises at least one locking tab comprising a cantilevered section in a circumferential wall of the second portion, wherein the at least one locking tab comprises a keyed end.

16. The patch pump system of claim 15, wherein the at least one locking tab is formed between axially-oriented slits in the circumferential wall of the second portion.

17. A method of filling a patch pump device, the method including the steps of:

coupling a first end of a first portion of a filling adapter to a medicament container;

locking a second end of a second portion of the filling adapter to a filling port on a patch pump device to rotate a shutter proximate the filling port about a pin from a closed position preventing access to the filing port to an open position allowing access to the filling port, wherein the shutter comprises;

a central portion and at least one wing portion extending therefrom, wherein the at least one wing portion is configured to prevent access to the filling port in the closed position, and

an opening disposed in the central portion, wherein the opening is configured to receive the pin therein;

engaging a protrusion disposed on a rim of the second portion with the opening of the central portion of the shutter to rotate the shutter from the closed position to the open position upon rotation of the filling adapter; and

filling a reservoir of the patch pump device with medicament from the medicament container via the filling port.

18. The method of claim 17, wherein coupling the first end of the filling adapter to the medicament container comprises receiving at least a portion of the medicament container in a recess of the filling adapter.

19. The method of claim 17, wherein coupling the first end of the filling adapter to the medicament container comprises piercing the medicament container with a needle.

20. The method of claim 17, wherein coupling the second end of the filling adapter to the filling port on the patch pump device comprises inserting a mating surface of the second end into the patch pump device.

21. The method of claim 17, wherein the medicament container comprises at least one of a syringe, a pen, a cartridge, and a vial.

22. The method of claim 17, wherein filling the reservoir comprises transferring medicament from the medicament container under pressure.

23. The method of claim 17 further comprising, after coupling the first end of the filling adapter to the medicament container, drawing medicament into the medicament container.
