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 disposable housing assembly comprising;

a reservoir, the reservoir comprising an at least partially collapsible membrane assembly and a septum;

a reusable fill adapter base configured to releasably engage a reservoir assembly of the infusion pump assembly, the base comprising;

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

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

a vial adapter assembly comprising;

at least two vial fingers having a spring force and a bent portion configured to maintain the position of the fluid vial wherein the fluid vial overcomes the spring force, wherein when the vial adapter assembly is attached to the fluid vial, a predetermined length of separation distance is maintained between the bent portion and a top portion of the fluid vial comprising a septum;

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

a second needle having a first end configured to penetrate the septum of the fluid vial and a second end configured to penetrate the 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,

wherein when the fluid vial is removed from the vial adapter assembly, the fluid vial first moves the predetermined distance and the bent portion catches the top portion of the fluid vial, and wherein a tip of a needle is removed from the fluid in the fluid vial and is located inside the septum, whereby the fluid in the fluid vial will not continue to flow when the vial adapter assembly is being removed from the fluid vial.

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 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 with a volume of 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 disposable housing assembly comprising;

a reservoir, the reservoir comprising an at least partially collapsible membrane assembly and a septum;
