Claim Text:
1. A device for filling a flexible liquid medicament container with a liquid from a liquid reservoir, the device for filling a liquid medicament container comprising: a pressurizing chamber; an evacuation chamber; a first displacement piston sealingly and slideably arranged within the pressurizing chamber, wherein the first displacement piston defines a first inner volume within the pressurizing chamber; a second displacement piston sealingly and slideably arranged within the evacuation chamber, wherein the second displacement piston defines a second inner volume within the evacuation chamber; a reservoir adapter fluidly connected to the first inner volume of the pressurizing chamber and which connects to the liquid reservoir and allows an increased pressure to be transferred from the pressurizing chamber, containing a pressurizing gas, to the interior of the liquid reservoir thereby allowing the gas to contact the liquid within the liquid reservoir; and a valve that fluidly connects the flexible liquid medicament container to either the interior of the liquid reservoir via the reservoir adapter, or the second inner volume of the evacuation chamber.
