Preferably, depending on the patient's body mass index, the diameter of the opening structure of the sleeve is 1.5-5 cm; optimally, the diameter of the opening structure of the sleeve is 3 cm. The opening size of the opening structure at the bottom of the sleeve needs to meet the radius of the outer part of the abdominal wall of different intestinal stoma tissues. If the opening structure is too large, it will cause poor sealing and the enterostomy will slip out of the sleeve; if the opening structure is too small, it will increase It is difficult to sleeve the enterostomy, and even the situation that the sleeve cannot be inserted occurs.

Preferably, the height of the sleeve is 3cm, 2cm or 1.5cm. Choose the appropriate sleeve according to the size of the enterostomy. The sleeve is divided into three sizes: large, medium, and small, and the corresponding sleeve height is 3cm, 2cm or 1.5cm. The large size sleeve is suitable for colostomy patients or small bowel stoma patients with a body mass index higher than the general population, the medium size protection sleeve is suitable for small bowel stoma patients with a normal body mass index, and the small size protection sleeve is suitable for people with a lower body mass index than the general population patients with small bowel stoma.

Preferably, the surface of the cover body is provided with a sterile layer, so that the sterile enterostomy protective cover can be applied to the enterostomy tissue after the operation area is sterilized.

The beneficial effect of the utility model is that the structure is simple, the operation is convenient, the small intestine and the colostomy exposed outside the abdominal wall are sealed, the positioning and fastening effect is good, and the enterostomy outside the abdominal wall can be completely wrapped. Tissue, with little side damage, avoiding additional pollution of the bacteria on the surface of the enterostomy to the surrounding skin incision and the interior of the abdominal cavity, and preventing the operator from incision and injury caused by unavoidable contact with the enterostomy tissue outside the abdominal wall or overflow of intestinal fluid. Contamination of the abdominal cavity. To reduce the risk of incision and abdominal infection and the incidence of infection in patients receiving "enterostomy return operation".
