Background

Colostomy refers to an artificial opening made in the abdominal wall during surgery for the treatment of intestinal diseases, a section of intestinal canal is pulled out of the opening and turned over to be sewn on the abdominal wall, thereby forming an enterostomy. The function is to replace the original anus of the perineum to perform the defecation function. Colorectal ostomy prolapse is a postoperative complication, and usually has clinical manifestations such as edema and inflammation of affected parts, and symptoms such as intestinal torsion and angina can appear for patients with serious illness. Colorectal stomal prolapse is a long-term complication after an intestinal operation stoma, and generally occurs because the cause is related to the size of the stoma itself after the operation, and if the stoma opening is relatively too large, when the patient is in a standing position, the abdominal pressure increases, which can press the intestinal canal out of the stoma. Usually manifests as stomal edema, hemorrhage, etc., and severe cases may have symptoms such as intestinal torsion, obstruction and even ischemic necrosis. Once such lesions occur, the patient will have a great influence on the health of the patient, and attention should be paid to them.

The technical scheme for preventing the prolapse of the stoma in clinic in the prior art is to fix a nipple on a bottom ring of a stoma chassis, plug the nipple at a distal end opening, and fix the nipple on a stoma base or an application by using a rope so as to prevent the intestinal stoma from being reeled out. However, when the patient moves or the intestinal tract moves, the lower end of the nipple is directly placed in the intestinal canal, and the intestinal canal can be separated from the nipple, so that excrement overflows to the periphery of the stoma to form pollution, or the stoma is separated again.

In view of the above, there is a need for an anti-stomal prolapse device that meets the corresponding needs.
