摘要：
A fluid drug delivery system comprises a rigid shell having an inner sidewall, an opening and a passage as well as a collapsible cartridge with a distal end and a proximal end. The collapsible cartridge is arranged within the shell with its distal end being closer to the opening than the proximal end. It further comprises a first portion including the proximal end and a second portion including the distal end. The second portion is recoilable from the inner sidewall to urge a fluid, which comprises a drug and is contained in the collapsible cartridge, to the passage of the rigid shell. Further, the rigid shell and the collapsible cartridge are co-extruded.
