  • Publication number: 20220040044
    Abstract: Various aspects of the subject disclosure relate to a compounder system having a cartridge that includes controllable fluid pathways. One or more rotary piston pump/valves may be used to move fluid and/or gasses through the various fluid pathways of the cartridge. For example, the cartridge may include a dedicated rotary piston pump/valve for each process that moves fluid and/or gas through the cartridge. When turning, the rotary piston pump/valve acts as a pump to move the fluid or gas, and when the rotary piston pump/valve stops turning, it effectively acts as a shutoff valve, preventing any fluid flow. Magnetic couplers for the cartridge may be provided on a pump head of the compounder system.
