Abstract

The invention discloses a device for replacement of a stomach and intestine fistula. The device comprises a fistula body, a fistula replacement joint, an inflatable gasbag, an inflatable vent valve and a constraint pad; the fistula replacement joint is connected with one end of the fistula body, and provided with a center channel and a valve element for cutting off the center channel; the valve element is provided with an opening part, and the opening part can achieve gas sealing when an external apparatus penetrates through the opening part, and achieve automatic closing after the external apparatus is drawn out; the fistula body penetrates through the inflatable gasbag, and the inflatable gasbag is connected with the side wall of the fistula body; the fistula body comprises a center through hole and an inflatable channel; the center through hole is communicated with the center channel of the fistula replacement joint, and the inflatable channel is communicated with the inflatable gasbag and the inflatable vent valve separately. The constraint pad sleeves the fistula body, and can seal the surrounding skin area of an abdominal incision for inserting the stomach and intestine fistula. Friction force between the constraint pad and the fistula body can keep the relative positions of the constraint pad and the fistula body constant. By means of the device, a clinical operator conveniently and quickly replaces the stomach and intestine fistula.

Description

technical field [0001] The invention relates to a device for replacing a gastroenterostomy tube. Background technique [0002] Gastroenterostomy is a nutritional support treatment for diseases such as swallowing dysfunction and digestive tract tumors. After the operation, the patient is injected with food through an external ostomy tube. Although the gastroenterostomy tube can be left in the patient's body for a long time, it also has a certain indwelling period. After the indwelling period is reached, it must be replaced. The old gastroenterostomy tube is removed and replaced with a new one. Enterostomy tube. Due to the lack of special tools for replacing gastroenterostomy tubes, it takes a long time for operators to complete the replacement of gastroenterostomy tubes, which not only affects work efficiency, but also increases the suffering of patients. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device ...
