Abstract

An infusion system includes a disposable wearable infusion device and a filler device. The disposable infusion device has a body arranged to be adhered to a patient'"'"'s skin and a reservoir for holding a liquid medicant to be infused into the patient. The filler device is arranged to detachably receive the infusion device body and to transfer a volume of the liquid medicant to the infusion device reservoir. The filler device may be part of a service device arranged to detachably receive the infusion device and which also includes a cannula driver and a cannula for providing the infusion device with a cannula and deploying the cannula to beneath a patient'"'"'s skin.

Claims

1. An infusion system comprising:

a disposable wearable infusion device having a body arranged to be adhered to a patients skin and a reservoir for holding a liquid medicant to be infused into the patient; and

a filler device arranged to detachably receive the infusion device body and transfer a volume of the liquid medicant to the infusion device reservoir.

2. The system of claim 1 wherein the infusion device includes a window through which the liquid medicant within the reservoir may be viewed.

3. The system of claim 1, wherein the filler device has a cavity for receiving a vial of the liquid medicant, and establishes fluid communication between the infusion device reservoir and the liquid medicant upon concurrently receiving the infusion device body and the vial of liquid medicant.

4. The system of claim 3, wherein the filler device is arranged to transfer a desired volume of the liquid medicant from the vial to the infusion device reservoir.

5. The system of claim 3, wherein the filler is arranged to meter a predetermined volume of medicant from the vial to the reservoir.

6. The system of claim 3, wherein the filler device is enabled to transfer a volume of the liquid medicant to the infusion device reservoir upon the cavity receiving the vial of the liquid medicant.

7. The system of claim 3, wherein the filler includes a pump that transfers the liquid medicant from the vial to the infusion device reservoir.

8. The system of claim 7, wherein the pump is arranged to pump air into the vial to displace liquid medicant from the vial and into the reservoir.

9. The system of claim 8, wherein the filler includes a vent that vents the vial to atmospheric pressure when being received in the cavity.

10. The system of claim 9, wherein the filler cavity seals the vial after the vent vents the vial to atmosphere as the cavity receives the vial.

11-14. -14. (canceled)

16-26. -26. (canceled)

27. An infusion system comprising:

a disposable wearable infusion device having a body arranged to be adhered to a patient'"'"'s skin and a reservoir for holding a liquid medicant to be infused into the patient; and

a service device arranged to detachably receive the infusion device body and having a filler that provides the infusion device reservoir with the liquid medicant and a cannula driver including a cannula, the cannula driver being arranged to drive the cannula into a deployed position extending from the infusion device to beneath the patient'"'"'s skin.

28. The system of claim 27 wherein the device includes a window through which the liquid medicant within the reservoir may be observed.

29. The system of claim 27, wherein the service device includes a cavity for receiving a vial of the liquid medicant, and wherein the filler establishes fluid communication between the infusion device reservoir and the liquid medicant upon the service device concurrently receiving the infusion device body and the vial of liquid medicant.

30. The system of claim 29, wherein the filler is enabled to transfer a volume of the liquid medicant to the infusion device reservoir upon the cavity of the service device receiving the vial of the liquid medicant.

31. The system of claim 29, wherein the filler is arranged to transfer a desired volume of liquid medicant from the vial to the infusion device reservoir.

32. The system of claim 29, wherein the filler is arranged to meter a predetermined volume of liquid medicant from the vial to the reservoir.

33. The system of claim 29, wherein the filler includes a pump that transfers the liquid medicant from the vial to the infusion device reservoir.

34. The system of claim 33, wherein the pump is arranged to pump air into the vial to displace liquid medicant from the vial and into the reservoir.

35. The system of claim 34, wherein the filler includes a vent that vents the vial to atmospheric pressure when being received in the cavity.

36. The system of claim 35, wherein the filler cavity seals the vial after the vent vents the vial to atmospheric pressure as the cavity receives the vial.

37. A filler device for filling a reservoir of a disposable wearable infusion device with a liquid medicant, comprising:

a body arranged to detachably receive the infusion device and having a cavity for receiving a vial of the liquid medicant;

a conduit that establishes fluid communication between the infusion device reservoir and the liquid medicant; and

a pump that transfers a volume of the liquid medicant from the vial to the infusion device reservoir.

38. The device of claim 37, wherein the pump is enabled to transfer a volume of the liquid medicant to the infusion device reservoir upon the cavity receiving the vial of the liquid medicant.

39. The device of claim 37, wherein the conduit establishes fluid communication between the infusion device reservoir and the liquid medicant upon the device concurrently receiving the infusion device and the vial of liquid medicant.

40. The device of claim 37, wherein the filler device is arranged to transfer a desired volume of the liquid medicant from the vial to the infusion device reservoir.

41. The device of claim 37, wherein the filler device is arranged to meter a predetermined volume of liquid medicant from the vial to the reservoir.

42. The device of claim 37, wherein the pump is arranged to pump air into the vial to displace liquid medicant from the vial and into the reservoir.

43. The device of claim 42, further comprising a vent that vents the vial to atmospheric pressure when being received in the cavity.

44. The device of claim 43, wherein the cavity seals the vial after the vent vents the vial to atmospheric pressure as the cavity receives the vial.

45. A service device for use with a disposable wearable infusion device having a reservoir for holding a liquid medicant to be infused into a patient, comprising:

a body arranged to detachably receive the infusion device and having a cavity for receiving a vial of the liquid medicant;

a filler that provides the infusion device reservoir with a volume of the liquid medicant from the vial; and

a cannula driver including a cannula, the cannula driver being arranged to drive the cannula into a deployed position extending from the infusion device to beneath the patient'"'"'s skin.

46. The device of claim 45, wherein the filler is enabled to transfer a volume of the liquid medicant to the infusion device reservoir upon the cavity receiving the vial of the liquid medicant.

47. The device of claim 45, wherein the filler establishes fluid communication between the infusion device reservoir and the liquid medicant upon the service device concurrently receiving the infusion device and the vial of liquid medicant.
