Abstract

A fill adapter system for an infusion pump assembly. The system includes a reusable fill adapter base, the base including a volume control mechanism to adjust an available fill volume of a reservoir of the infusion pump assembly and a pump mechanism configured to pump air into a fluid vial. The system also includes a vial adapter assembly including a first needle configured to penetrate a septum of the fluid vial for fluidly coupling the pump mechanism to the fluid vial and a second needle having a first end configured to penetrate the septum of the fluid vial and a second end configured to penetrate a septum of the reservoir of the infusion pump assembly to allow transfer of fluid from the fluid vial to the reservoir of the infusion pump assembly in response to air being pumped into the fluid vial and a needle carriage adapted to carry the first needle and the second needle, wherein the needle carriage slidably attached to the interior of the vial adapter assembly, wherein the needle carriage adapted to slide from a vial end of the vial adapter to a receptacle end of the vial adapter.

Claims

1. A fill adapter system for an infusion pump assembly comprising:

a reusable fill adapter base, the base comprising;

a volume control mechanism to adjust an available fill volume of a reservoir of the infusion pump assembly; and

a pump mechanism configured to pump air into a fluid vial; and

a vial adapter assembly comprising;

a first needle configured to penetrate a septum of the fluid vial for fluidly coupling the pump mechanism to the fluid vial; and

a second needle having a first end configured to penetrate the septum of the fluid vial and a second end configured to penetrate a septum of the reservoir of the infusion pump assembly to allow transfer of fluid from the fluid vial to the reservoir of the infusion pump assembly in response to air being pumped into the fluid vial; and

a needle carriage adapted to carry the first needle and the second needle, wherein the needle carriage slidably attached to the interior of the vial adapter assembly, wherein the needle carriage adapted to slide from a vial end of the vial adapter to a receptacle end of the vial adapter.

2. The fill adapter of claim 1 wherein the vial adapter assembly further comprising a hydrophobic filter within a fluid path of the first needle.

3. The fill adapter of claim 1 wherein the volume control mechanism further comprising a turn dial and a push plate, wherein the turn dial actuates the push plate and wherein the push plate adjusts the available fill volume of a reservoir of the infusion pump assembly.

4. The filling system of claim 1 further comprising a weight scale, the weight scale determining the weight of the infusion pump assembly before filling a volume a fluid and the weight scale determining the weight of the infusion pump assembly after the reservoir is filled to a volume.

5. A filling system for an infusion pump assembly comprising:

a volume control mechanism configured to adjust an available fill volume of a reservoir of the infusion pump assembly;

a pump mechanism configured to pump air into a fluid vial via a first needle, the first needle configured to penetrate a septum of the fluid vial for fluidly coupling the pump mechanism to the fluid vial; and

a second needle having a first end configured to penetrate the septum of the fluid vial and a second end configured to penetrate a septum of the reservoir of the infusion pump assembly to allow transfer of fluid from the fluid vial to the reservoir of the infusion pump assembly in response to air being pumped into the fluid vial.

6. The filling system of claim 5 wherein the volume control mechanism further comprising a turn dial and a push plate, wherein the turn dial actuates the push plate and wherein the push plate adjusts the available fill volume of a reservoir of the infusion pump assembly

7. The filling system of claim 5 further comprising a weight scale, the weight scale determining the weight of the infusion pump assembly before filling a volume a fluid and the weight scale determining the weight of the infusion pump assembly after the reservoir is filled to a volume.

8. A vial adapter comprising:

a housing having a vial end and a receptacle end and interior wall features;

a needle carriage slidably attached to the interior of the housing; and

a disc slidably attached to the interior of the housing, the disc having a first position on the receptacle end of the housing and a second position on the vial end of the housing and configured to matably attach to the needle carriage,

wherein the needle carriage matably attaches to the disc and the needle carriage and disc slide to the vial end of the housing and wherein the disc is locked into a position on the vial end by interior wall features of the housing.

9. The vial adapter of claim 8 further comprising at least one locking feature, the locking feature adapted to mate with at least one key feature on a fill adapter base.
