Liquid storage and delivery system
First Claim
1. A liquid storage and delivery system including a reusable control and drive unit, a container, a pump interface sealingly fixed to the container, a pump module fluidically connected to the container, and a coupling system configured for removably coupling the pump module to the control and drive unit, the pump module comprising a rotary pump engine comprising a stator fixed to or integrally formed with the pump interface and a rotor rotatably movable in the stator, and a pump outlet, the coupling system comprising a transmission input coupling coupled to the rotor of the pump engine, the control and drive unit comprising a pump drive configured to mechanically engage the transmission input coupling of the pump module when the pump module is coupled to the control and drive unit, wherein the container is in the form of a flexible pouch and the pump module is arranged external to the flexible pouch and forms therewith a disposable unit, and wherein the rotor of the rotary pump engine is further axially movable during a pumping operation mode.

Abstract
The invention relates to a liquid storage and delivery system including a reusable housing (8) comprising a control and drive unit, a container (2), a pump module (4) fluidically connected to the container (2), and a coupling system (6) configured for removably coupling the pump module (4) to the control and drive unit (6). The pump module comprises a pump engine (20), a pump outlet (22), and a transmission input coupling (18) coupled to the pump engine (20). The housing comprising the control and drive unit also comprises a pump drive (34) configured to engage the transmission input coupling (18) of the pump module (4) when the pump module (4) is coupled to the housing comprising the control and drive unit. The container (2) is in the form of a flexible pouch and the pump module (4) is permanently integrated with the flexible pouch and forms therewith a disposable unit.
