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.
