Description

Technical Field

[0001] This utility model belongs to the field of medical and nursing technology, and specifically relates to a two-piece ostomy bag. Background Technology

[0002] Colostomy is currently an important surgical method for rectal cancer and digestive system diseases. It is used to treat intestinal tumors, intestinal obstruction, intestinal necrosis, and related diseases that affect normal bowel function. In recent years, influenced by factors such as the rising incidence of gastrointestinal diseases, the number of people requiring colostomy has steadily increased. Colostomy surgery has become a major technique for treating various intestinal diseases. Depending on the disease, the surgery is divided into permanent colostomy and temporary colostomy.

[0003] After ostomy surgery, ostomy bags are needed for bowel movements. Ostomy patients must wear these bags to collect feces, and the ostomy also alters their original bowel habits and lifestyle, causing inconvenience. Currently, commonly used ostomy products are divided into one-piece and two-piece ostomy bags. One-piece ostomy bags are directly glued on, while two-piece ostomy bags have a separate base and bag. The connection between the base and bag requires pressing and fastening, which greatly increases pain for ostomy patients, especially in the early postoperative period. Furthermore, some elderly patients or their families have difficulty operating the bag independently. Adjusting the direction of the ostomy bag requires removing it, and reinstalling it is troublesome and difficult. Leakage is also a common problem at the connection point between the ostomy bag and the base, significantly impacting the patient's physical and mental health. In addition, existing ostomy bags lack markings; generally, the bag should be emptied when it is more than one-third or one-half full, but patients often cannot accurately judge this measurement.

[0004] Against this background, the present invention proposes a new technical solution. Utility Model Content
