Anal tube exhaust and defecation device with air bag

Abstract

The invention discloses an anal tube exhaust and defecation device with an air bag. The anal tube exhaust and defecation device comprises an anal tube, the air bag and a ventilation tube. The anal tube is cylindrical, and the inner diameter of the anal tube is 1.2-2.5 cm; the air bag is arranged on the outer side of the end, entering the anus, of the anal tube and fixedly connected with the anal tube; one end of the ventilation tube penetrates through the anal tube from the inner side of the anal tube and is connected and communicates with the air bag, and the other end of the ventilation tubeis provided with a valve; and a boss is arranged on the outer side of the other end, away from the end entering the anus, of the anal tube and is annular, and a fixing hole for fixing is formed in the upper portion of the boss. The anal tube exhaust and defecation device is mainly used for preventing anastomotic fistula after a low rectal cancer operation, and complications of the anastomotic fistula can be prevented through the device.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an anal canal exhaust and defecation device with an air bag. Background technique [0002] Anorectal disease is a common and frequently-occurring disease unique to humans. Rectal cancer is a malignant tumor with a relatively high incidence rate in my country in recent years. The incidence of rectal cancer in my country is characterized by the middle and low position (cancer located within 7cm from the dentate line and under the peritoneal reflexion), accounting for about 20% of rectal cancer. 70% to 75%. There is currently no precise definition of low rectal cancer. Anatomically, the anal canal is about 2cm long in males and 1.5cm in females. The rectum is 12-15cm long and can be divided into upper, middle and lower parts. Therefore, low rectal cancer is usually defined as rectal cancer that is <5 cm from the anal verge or <3 cm from the anorectal junction, and...

Problems solved by technology

After radical resection of low rectal cancer, intestinal anastomosis is performed. Due to intestinal peristalsis, intestinal contents, including gas and liquid, move to the anastomosis close to the anus, and the anus often maintains a contracted and tense state due to the existence of the sphincter, so the intestinal contents move to the anus. When there is accumulation at the anastomotic site of the intestinal tract, the local pressure rises, causing greater tension on the anastomosis, so anastomotic leakage is prone to occur
