Ostomy bag device with negative pressure drainage function

Technical Field

The utility model relates to the field of medical appliances, in particular to an ostomy bag device with a negative pressure drainage function.

Background

Gastrointestinal ostomy is a common procedure in gastrointestinal surgery. Patients with partial gastrointestinal disease require single or double lumen ostomy by pulling a portion of the intestinal tube to the abdominal wall due to obstruction of the distal end of the gastrointestinal tract or the need for postoperative recovery. The intestinal contents, including fecal water and the like, are discharged through the stoma, which requires an ostomy bag outside the stoma for collecting the intestinal contents, avoiding the contamination of clothing and the like by the intestinal contents and reducing the psychological burden on the patient caused by the direct outflow of the intestinal contents.

Ostomy bags commonly used during recovery during hospitalization are two-piece, including chassis and ostomy bags. The chassis is adhered to the abdominal wall mainly through viscose, and plays a role in fixation. The ostomy bag is responsible for engaging the chassis and serves to contain intestinal contents and faeces. However, for patients with lesions around the stoma such as a side leakage of the stoma and separation of the mucous membrane of the stoma, when the disposable ostomy bag is used, the fecal water is easy to stay at the position of the stoma on the chassis, and the fecal water dermatitis is easy to be caused under the condition that the skin around the stoma is not healed, so that digestive juice discharged from the stoma permeates into the wound, healing of the wound around the stoma is further delayed, and even serious infection and complications around the stoma are caused by inflammation diffusion. Thus, for post-ostomy patients, or patients with peristomal complications, it is desirable for the healthcare staff to keep the peristomal skin clean, preventing severe infections secondary to inflammation spread. And frequent cleaning of the stoma and replacement of the ostomy bag to keep the stoma clean takes time and effort.

Therefore, the ostomy bag device for the postoperative hospitalization recovery process for keeping the stoma clean is designed to achieve the purposes of saving time and labor and having a certain treatment function.
