Abstract

An infusion pump system is described that increases patient comfort and convenience. The infusion pump system includes an infusion site interface that is releasably connected to an infusion pump body, and has no tubing associated between the infusion site interface and the pump body. The infusion pump body may include a carrier frame that may be adhered to the skin of a user.

Claims

1. An infusion pump system, comprising:

an infusion site interface including a soft cannula for penetration of the skin when the interface is installed, and a hub that rises above the upper surface of the interface when the interface is installed, wherein the infusion site interface lacks tubing above the upper surface of the interface; and

an infusion pump body, wherein the infusion pump body can be releasably connected to the infusion site interface to form a direct connection between the infusion pump body and the infusion site interface.

2. The system of claim 1, wherein the infusion site interface is adhesively attached to the infusion site on a body.

3. The system of claim 1, further comprising an adhesive on the pump body that enables temporary adhesion of the pump body to another surface.

4. The system of claim 1, wherein the infusion site interface further comprises a carrier frame having an adhesive on the upper surface, enabling temporary adhesion of the pump body to the upper surface of the carrier frame.

5. The system of claim 1, wherein the exit port of the infusion pump body connects directly to an entry port on the infusion site interface.

6. The system of claim 1, wherein the pump body releasably connects to the infusion site interface using a locking mechanism on the hub of the infusion site interface.

7. The system of claim 1, wherein the pump body releasably connects to the infusion site interface using a guide on the hub of the infusion site interface.

8. The system of claim 1, wherein the pump body releasably connects to the infusion site interface using the penetration of a pump body exit port through an infusion site interface septum.

9. The system of claim 8, wherein the pump body exit port comprises a needle.

10. The system of claim 1 wherein the infusion pump body further comprises a control system.

11. The system of claim 1, wherein the infusion site interface further comprises a carrier frame, wherein the carrier frame is adhesively connected to a body near an infusion site location, and the carrier frame is connected to the hub.

12. The system of claim 11, wherein the carrier frame is connected to the hub via structural supports between the hub and an outer frame.

13. The system of claim 11, wherein the carrier frame comprises a webbing.

14. The system of claim 1, wherein the infusion site interface has no tubing external to the skin of a user after installation of the infusion site interface.

15. A method of operating an infusion pump system, comprising:

dispensing medicament from a medicament reservoir in a pump body through a pump body exit port into an infusion site interface,

wherein there is a direct connection between the infusion pump body and the infusion site interface during the dispensing, and wherein the pump body is releasably connected to the infusion site interface.

16. The method of claim 15, wherein the pump body exit port comprises a catheter that penetrates a septum of the infusion site interface.

17. The method of claim 16, wherein the catheter comprises a needle.

18. The method of claim 15, wherein the pump body exit port connects directly to an entry port on the infusion site interface.

19. The method of claim 15, wherein the pump body releasably connects to the infusion site interface using a locking mechanism.

20. The method of claim 15, wherein the pump body releasably connects to the infusion site interface using a guide on the infusion site interface.

21. The method of claim 15, wherein the pump body releasably connects to the infusion site interface using only the penetration of the pump body exit port through an infusion site interface septum.

22. The method of claim 15, wherein the infusion site interface is adhesively attached to the infusion site on a body.

23. The method of claim 15, wherein the pump body is adhesively attached near the infusion site.

24. The method of claim 15, wherein the pump body is adhesively attached to an upper surface of the infusion site interface.

25. The method of claim 15, wherein the pump body is adhesively attached using a single layer adhesive.

26. An infusion pump system, comprising:

an infusion site interface including a soft cannula for penetration of the skin when the interface is installed, a carrier frame that can be adhesively attached to a body surface, and a hub that is connected to the carrier frame and rises above the carrier frame when the interface is installed; and

an infusion pump body, wherein the infusion pump body can be connected, detached, and re-connected to the infusion site interface as desired to form a direct connection between the infusion pump body and the infusion site interface.

27. An infusion pump system, comprising:

an infusion site interface including a soft cannula for penetration of the skin when the interface is installed, a carrier frame that can be adhesively attached to a body surface, and a hub that is connected to the carrier frame and rises above the carrier frame when the interface is installed; and

an infusion pump body that can be releasably connected to the infusion site interface, forming a direct connection between the infusion pump body and the infusion site interface; and

an adhesive surface on the infusion pump body.

28. The method of claim 27, wherein the adhesive surface is used to attach the infusion pump body to the infusion site interface.

29. The method of claim 27, wherein the adhesive surface is used to attach the infusion pump body near an infusion site.
