Background

The passage of intestinal contents through a disorder caused by any cause is collectively referred to as ileus. It is one of the common surgical acute abdominal disorders. Sometimes, the diagnosis of acute intestinal obstruction is difficult, the disease development is fast, and the patient is usually dead. Imbalance of water, electrolytes and acid-base balance, and patients with advanced age and heart-lung dysfunction are common causes of death.

Ileus is a common and frequently occurring surgical disease, the proximal intestinal canal of the ileus is obviously expanded, intestinal contents are deposited and fermented, bacteria are greatly propagated, toxins are obviously increased, and the pressure in the intestinal cavity and the pressure in the abdominal cavity are increased, so that multiple hazards are brought to patients, and therefore, the pressure reduction and lavage of the intestinal contents of the ileus are often required. Excessive intestinal contents and obstructed intestinal canal edema are seriously expanded and fragile, so that operation is seriously influenced, once the intestinal canal is ruptured, serious abdominal cavity infection is caused, meanwhile, the pure decompression can not completely remove the content of the intestinal canal, and the intestinal canal which is oedema and unclean is extremely easy to generate anastomotic fistula under the condition of intestinal canal excision anastomosis.

At present, a common decompression method is that after an intestinal canal is cut into a small opening, the intestinal canal is sleeved into a B ultrasonic protection sleeve belt and then directly extruded for removal; or after the purse string is sewn on the silk thread at the edge of the tie membrane, a small opening is cut, and the aspirator with the sleeve is directly placed into the tie membrane to be sucked under negative pressure, but the suction and the decompression under negative pressure are very easy to cause the blockage of the side hole of the aspirator to influence the decompression effect due to the suction of the intestinal wall under negative pressure, so that the mucosa is easily damaged and even the tie membrane is broken.
