Abstract

The invention is based on the intention of creating a stomach probe with which a watertight closure of the oesophagus is possible. The stomach probe, according to the invention, is characterized by a tampon-bladder for watertight closure of the oesophagus, in which the tampon-bladder forms from flexible and/or elastic material at least a closed inner cavity for the reception of a fluid medium, through a means (11) of establishing a prescribed pressure for the medium in the tampon-bladder (16) by an inner lumen forming the actual stomach probe, from which an outer hose-like lumen (18) extending to the tampon-bladder (16) is so arranged that between the outer lumen (18) and the inner lumen (17) a channel is formed connected to the inner cavity of the tampon-bladder (16) arranged on the outer lumen (18) by a number of openings (20), whereby the inner cavity of the tampon-bladder (16) is connected via the canal formed between the inner and outer lumina (17, 18) with the means of production of pressure in the tampon-bladder, that is, with a suitably graded reservoir or equalizing vessel (11) for the liquid medium situated above the tampon-bladder and outside the patient.
