Abstract

This invention provides a device for flushing and/or draining the stomach by means of a tube intended to be inserted through the oesophagus. A balloon in the form of a double-walled hollow cylinder elastically and hermetically encircles the tube periphery at a predetermined point in close contact with the same, and is releasably joined to the tube. The balloon is inflatable through a thin pipe extending to the proximal extremity of the tube.

Encircling terminal sections of the balloon are formed with increased thickness as compared to the remaining part of the balloon.

Prior to insertion of the tube into the oesophagus, the balloon is rolled up in the manner of a cuff on an obliquely-slotted sleeve which is slidable on to the tube, the balloon being thereafter unrolled from the sleeve to lie flat against the tube.

Claims

1. A device for flushing and/or draining a patient'"'"'s stomach comprising a tube for introduction into the stomach through the oesophagus, and a balloon in the form of a double-walled hollow cylinder elastically and hermetically encircling said tube periphery at a predetermined point and in close contact therewith, said balloon being releasably joined to said tube and being inflatable through a thin pipe extending to the proximal extremity of said tube, including an obliquely-slotted sleeve member which is slidable on said tube, said balloon being rolled up in the manner of a cuff on said sleeve member prior to introduction through the oesophagus, said balloon being subsequently unrollable from said sleeve member to lie flat against said tube.

2. A device according to claim 1, wherein the internal diameter of said sleeve member is variable by expanding the sleeve member for adaptation to the external diameter of said tube and wherein the overlapping areas of said oblique slot are denticulated to lock said sleeve member against diminution of the preset sleeve diameter by a kind of ratchet action.
