Background

When some patients suffer from intestinal canal or abdominal cavity lesions, tissue effusion can be formed in the abdominal cavity and needs to be periodically removed. Generally, an upper opening of the abdomen, i.e. an abdominal cavity stoma, is communicated with the abdominal cavity, and an ostomy bag is attached to the stoma. The care and change of ostomy bags is performed by a nurse twice a day. The accumulated liquid in the abdominal cavity of the patient can be timely discharged, and the pressure of the abdominal cavity is reduced. Although care is taken twice a day, a small amount of effusion in the abdominal cavity still flows out of the stoma between the treatments, so that the skin near the stoma is soaked by the effusion, and the skin is easy to itch and even fester. The ostomy bag is taken off in real time, and wiping the part of the skin requires a nurse to frequently change the ostomy bag, which is not feasible. Meanwhile, the ostomy bag is adhered to the skin around the stoma by using the adhesive, and the part of the skin can be pressed and injured after a long time, even pressure sores appear. There is thus a need to develop an ostomy bag with little damage to the skin near the stoma.
