Abstract: The present invention relates to a method for operating a feeding system for feeding a patient with a liquid feed, which liquid feed is stored in a reservoir, which reservoir is fluidically connected to a tube which has an inlet end for receiving the liquid feed from the reservoir and an outlet end for dispensing the liquid feed toward the patient and is adapted to convey said liquid feed contained in the reservoir to the patient. In order to reduce the volume of feed contained in the feeding system to be discharged after stopping the pumping device, the present invention provides a method and a feeding system allowing a purging phase ordered by the controller assigned to the pumping device, in which the supply of liquid from the reservoir is stopped and a purging fluid drives liquid feed contained in the tube toward the outlet end and wherein the controller stops the introduction of the purging fluid at the end of the purging phase.

Abstract: The invention relates to a pumping device for feeding liquid feed to a patient, which can be used and assembled economically. The pumping device has a pumping cartridge and a drive unit. The pumping cartridge provides a pumping chamber and a pumping channel and valve inlet and outlet locations. The drive unit comprises actuators for pumping and opening and closing the valves at the valve inlet and outlet locations and can releasably be connected with the pumping cartridge. While the pumping cartridge is a disposable part, the driving unit is provided for multiple uses for supplying batch of liquid feed to the patient.

Abstract: In an embodiment, a prosthetic leg including a modular knee element coupled to a modular ankle element. The modular knee element includes a knee motor rotatable about an axis of a shaft in the knee motor. The modular ankle element includes a drive portion coupled to a surface-contacting portion via a pylon having a top and bottom end.
