Gastric tube

摘要

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.

主权项

1. A gastric tube comprising:
an inflatable stopper; a supply cannula extending in the longitudinal direction for introduction into the oesophagus; a lumen extending in the longitudinal direction and superposed on the supply cannula in the region of the inflatable stopper, wherein the lumen is connected to the interior of the inflatable stopper, and wherein the lumen permits a rapid volume equalization between various regions of the inflatable stopper; and a separate molding body extending in the longitudinal direction and mounted on the supply cannula entirely within the inflatable stopper, wherein the separate molding body determines the shape of the lumen and has sufficient rigidity to ensure non-collapsible shifting volume, wherein the separate molding body defines a plurality of wall elements, a least one of the wall elements extending in the longitudinal direction in contact with the supply cannula and disposed in the interior of the inflatable stopper.
