摘要：
A disposable pump cartridge for a compounder system is provided. The cartridge may include a plurality of controllable fluid pathways and a piston for pumping fluid and/or vapors through selected ones of the fluid pathways. The cartridge may include a plurality of valves operable to select particular pathways from the plurality of pathways. The fluid pathways may be formed from a portion of a cartridge frame and a sealing membrane disposed on the cartridge frame. A cartridge bezel disposed over the sealing membrane may include openings that provide access to the valves. The valves and the piston may be operated by a pump drive of the compounder system. The bezel may include additional openings that provide access to ports within the cartridge for receiving diluents or for providing waste. Portions of the sealing membrane within the additional openings in the bezel may be configured to receive a needle therethrough.
