CA 2642877

With the invention, a gastric tube with an inflatable stopper and a supply cannula that can be introduced into the oesophagus and on which a lumen is superposed in the region of the inflatable stopper, which is connected to the interior of the inflatable stopper and permits a rapid volume equalization between different regions of the inflatable stopper, is to be improved in that the lumen which is located between the supply cannula and the inflatable stopper and connected to the interior of the inflatable stopper, can be produced in a technically simple manner and at the same time provides sufficient volume equalization between partial volumes of the inflatable stopper. This object is achieved by a gastric tube with an inflatable stopper in which a separate molding body is mounted on the supply cannula which determines the shape of the lumen.

L'objectif de la présente invention est de mettre au point une sonde gastrique comprenant un système de tamponnement gonflable et une canule d'alimentation qui peut être introduite dans l'oesophage et sur laquelle se superpose une lumière dans la région du système de tamponnement gonflable. Cette lumière communique avec l'intérieur du système de tamponnement gonflable. Il est possible d'améliorer une compensation de volume rapide entre différentes régions du système de tamponnement gonflable en ce que la lumière qui se trouve entre la canule d'alimentation et le système de tamponnement gonflable et qui communique avec l'intérieur du système de tamponnement gonflable est techniquement simple à réaliser et permet une compensation de volume suffisamment satisfaisante entre des volumes partiels du système de tamponnement gonflable. L'objectif est atteint par une sonde gastrique comprenant un système de tamponnement gonflable, dans laquelle un corps moulé détaché est appliqué sur la canule d'alimentation et permet de déterminer la configuration de la lumière.
