An enteral feeding unit that reduces the occurrence of gastro-esophogeal- pharynegalreflux during feeding includes an automatable feeding pump with a feedback sensorfor sensing a relative pressure in a patient's stomach and esophagus, anda regulator system for controlling and monitoring feeding rate to the patientas a function of the relative gastro-esophageal pressure. The system includesa stomach probe that provides a fluid-tight closure of the esophagus. The stomachprobe includes a tampon-bladder for watertight closure of the esophagus, inwhich the tampon-bladder is formed of flexible and/or elastic material. At leastan inner cavity of the bladder is provided for the reception of a fluid medium.A prescribed pressure for the medium in the tampon-bladder (53) is maintainedby an inner iumen forming the stomach probe, from which an outer hose-like lumen(62) extending to the tampon-bladder (53) is so arranged that between the outerlumen (62) and the inner lumen (61 ) a channel is formed connected to the inner cavityof the tampon-bladder (53) arranged on the outer lumen (62) by a number of openings(57). The inner cavity (58) of the tampon-bladder (53) is connected via a canalformed between the inner and outer lumina (62) with a suitably graded reservoiror equalizing vessel for the liquid medium situated above the tampon-bladderand outside the patient.
