Self-controlling artificial anal opening and closing device ----------------------------------------- ---------------------------------------
Deborah, a scientist at the Catholic University of Paraná, Brazil, has developed a "colostomy (artificial anus) opening and closing device", which is expected to help patients with artificial anus to relieve pain. In patients undergoing rectal resection, some people need to remove the anal canal and anus, and the defecation can only be done through the artificial anus installed on the abdominal wall. Since the artificial anus does not have an automatic contraction function, these patients must always wear a septic bag on the abdomen to receive the excrement, which is very inconvenient for life. The function of the colostomy opener is to enable the patient to control the closure of the artificial anus autonomously, eliminating the trouble of wearing a dung bag. The instrument is made of vinyl and is equipped with a micro motor that mimics the function of the sphincter. The user can control the artificial anus opening and closing to achieve free bowel movement. The instrument weighs 194 grams and can be implanted into the human body. The pressure of the instrument in the human body is only 33 mm Hg, which will not affect the normal activities of the patient. Deborah developed the colostomy opener from the early 1990s and continually modified it. He plans to further improve the instrument, reducing its weight to 100 grams and reducing the pressure in the human body to 12 mm Hg. ——Midi Medical Network
