Abstract:
1. A device for filling a flexible liquid medicament container with a liquid from a liquid medicament 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 pressurizing conduit fluidly connected to the first inner volume of the pressurizing chamber; a reservoir adapter fluidly connected directly to the pressurizing conduit and which connects to a 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 a liquid within the reservoir; An evacuation conduit fluidly connected directly to the second inner volume of the evacuation chamber; a container adapter fluidly connected directly to the evacuation conduit and which connects with a flexible container; a transfer conduit fluidly connected directly to the reservoir adapter and the container adapter; and a valve that fluidly connects the container adapter to either the evacuation conduit or the transfer conduit.
