Description

Technical Field

[0001] The utility model belongs to the technical field of gastrointestinal negative pressure suction equipment, and in particular relates to a gastrointestinal negative pressure suction equipment. Background Art

[0002] Gastrointestinal decompression surgery utilizes the principles of negative pressure attraction and siphoning. A gastric tube is inserted through the oral or nasal cavity to suck out the gas and fluid accumulated in the gastrointestinal tract. This can reduce the pressure and expansion in the gastrointestinal tract for patients with gastrointestinal obstruction, prevent gastrointestinal contents from continuing to leak into the abdominal cavity through the rupture for patients with gastrointestinal perforation, and facilitate the healing of the anastomosis after gastrointestinal anastomosis.

[0003] There are still some problems with the existing negative pressure suction equipment. In order to ensure the smooth progress of the negative pressure suction work, the existing gastric tube and the drainage tube head are split structures. The drainage tube head can be inserted into the tail of the gastric tube through the pagoda joint of the drainage tube head, so that the gastric tube and the drainage tube head can form an integrated structure, so as to suck out the gas or fluid in the patient's gastrointestinal area. The existing installation method is to directly insert the pagoda joint of the conical drainage tube head into the tail of the gastric tube. After the installation is completed, there will be a gap between the pagoda joint and the tail tube of the gastric tube, which will cause the sucked gas or liquid to leak. At the same time, the existing air inlet and outlet pipes have only one main pipe, and when the pipe is blocked, it will cause the failure of gastrointestinal negative pressure suction.

[0004] Therefore, how to complete the gastrointestinal negative pressure suction work on the patient is a problem that needs to be solved at present. Utility Model Content
