Device, Kit, And Method For Filling a Flexible Reservoir Container In A Negative Pressure Chamber
First Claim
1. A device for transferring a liquid medicament from a supply container to a flexible reservoir container, with a compartment unit and an adapter unit;
- wherein the compartment unit comprises a sealingly closable evacuation chamber, arranged for housing the flexible reservoir container and for being fluidly connected with a pump mechanism; and
wherein the adapter unit comprises at least one transfer passage for transferring liquid from a supply container connected to the adapter unit to the flexible reservoir container, and a separator arranged in the transfer passage for separating gas bubbles from a liquid streaming through the transfer passage, the separator being fluidly connected to the chamber.

Abstract
A device, kit, and method for transferring a liquid medicament from a supply container to a flexible reservoir container are disclosed. The device may comprise a compartment unit and an adapter unit. The compartment unit may have a sealingly closable chamber, arranged for housing the flexible reservoir container and for being fluidly connected with a pump mechanism. The adapter unit may have at least one transfer passage for transferring liquid from a supply container connected to the adapter unit to the flexible reservoir container, and a separator arranged in the transfer passage for separating gas bubbles from a liquid streaming through the transfer passage. The separator may be fluidly connected to the chamber.

14. A method for transferring a liquid medicament from a supply container to a flexible reservoir container, the method comprising:
-
providing a fluid connection between the supply container and the flexible reservoir container; providing a separator arranged in the fluid connection for separating gas bubbles from the liquid; subjecting the flexible reservoir container to a reduced ambient pressure, thereby generating a negative pressure inside of the flexible reservoir container; sustaining normal ambient pressure inside of the supply container; subjecting the separator to the reduced ambient pressure, wherein the separation of the gas bubbles from the liquid in the separator is effected by the pressure difference between the liquid and the reduced ambient pressure; and conveying the liquid from the supply container to the flexible reservoir container, driven by the pressure difference between the inside of the supply container and the inside of the flexible reservoir container. - View Dependent Claims (15)
