[0002] Gastrointestinal decompression is a method in which a gastric tube is inserted from the oral or nasal cavity, connected to a disposable gastrointestinal decompression device, and the gastric contents are drawn out of the patient's body under the action of negative pressure and siphon principle. This method can suck out the gas or liquid in the gastrointestinal tract, reduce the pressure in the gastrointestinal tract, reduce the degree of gastrointestinal distension, improve the blood circulation of the gastrointestinal wall, and promote the healing of stomach wounds and the recovery of function. Existing gastrointestinal decompression is usually just a catheter that can only absorb the gas or liquid in the intestinal cavity, and cannot support the intestinal cavity. Therefore, it is easy to adsorb on the inner wall of the intestinal cavity and easily block the suction hole, resulting in low absorption effect. The decompression surgery effect is not ideal, and the larger solid particles in the intestinal cavity are also easy to block the suction hole. Therefore, there is an urgent need for a device that can effectively decompress the intestinal cavity and prevent blockage. Summary of the invention

[0031] To further elaborate, in order to prevent air leakage, a one-way valve 10 is also provided at the inflation end of the inflation tube 4, which opens the inflation tube 4 when the syringe or inflation pump is inserted and closes the inflation tube 4 when it is pulled out.

[0032] In further detail, the catheter body 1 is also provided with an inflation cavity 11, and a notch is provided on the inflation cavity 11 for sealingly connecting the inflation tube 4. The catheter body 1 is also provided with a plurality of inflation ports, and each inflation port corresponds to a support airbag 3. The above-mentioned structure can reduce the length of the inflation tube 4. The inflation tube 4 is placed in the inflation cavity 11, which is difficult to process. Therefore, only one section needs to be inserted for sealing.

[0033] 11 Ventilation can greatly reduce processing difficulty and reduce costs.

[0034] To further elaborate, in order to enhance the sealing performance, the support balloon 3 is integrated with the outer wall of the catheter body 1 and is inflated and deflated through the inflation port.

[0035] Preferably, the maximum diameter of the support airbag 3 in a filled state is 1 to 3 cm.

[0036] Preferably, in order to obtain better supporting and pressurizing effects, the supporting airbags 3 are evenly arranged on the catheter body 1 , and the suction holes 2 are arranged between two adjacent supporting airbags 3 and evenly arranged around the catheter body 1 .

[0037] Preferably, in order to facilitate medical personnel to check the size of lesions, such as the size of lesions, tumors, etc., a scale 12 for checking the size of lesions is further provided on the catheter body 1, and the range of the scale 12 is 0 to 10 cm.
