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.

A method for operating a feeding system for feeding a newborn 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 newborn and is adapted to convey said liquid feed contained in the reservoir to the newborn, and a pumping device adapted to convey the liquid feed from the reservoir through the tube to the newborn, wherein at the end of the feeding a controller orders a purging phase in which the supply of the liquid feed from the reservoir is stopped and a purging fluid is introduced into the tube, which 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.
A feeding system for feeding a patient with a liquid feed, comprising a liquid feed reservoir, a tube in fluid communication with said reservoir, which tube has an inlet end for receiving the liquid feed and an outlet end for dispensing the liquid feed toward the patient, a pumping device adapted to convey the liquid feed from the reservoir through the tube to the patient and a controller for controlling operation of the pumping device, wherein the feeding system further comprises a purge inlet which can be brought in fluid communication with the tube, wherein the controller is adapted to control a purging phase in which the supply of the liquid feed from the reservoir is stopped and a purging fluid is allowed to be introduced via the purge inlet into the tube, which purging fluid drives liquid feed contained in the tube toward the outlet end, wherein the controller determines the volume of purging fluid to be pumped through the tube on the basis of
