Description

Anal fistula exhaust drainage tube

Technical Field

The invention relates to a medical auxiliary instrument for a digestive tract.

Background

The anorectal part of the anal canal at the tail end of the human digestive tract is an important channel for 'sewage discharge', and the joint part of the anal canal and the rectum is provided with an anal crypt, an anal gland catheter and an anal gland. Feces are retained in the anal crypt, and once bacteria invade the anal crypt, anal gland duct or anal gland, anal inflammation can be caused, and perianal abscess can be caused; after the perianal abscess extends to the skin around the anus and is broken, pus is discharged, and the pus cavity is gradually reduced to form anal fistula. The method for treating anal fistula mainly comprises surgical operations, such as anal fistula resection and thread-hanging therapy; the principle of these procedures is to cut open the fistula tract to form an open wound that promotes healing. The healing of the wound surface needs one to twenty days, liquid such as pus and the like can be discharged from the wound surface in the healing period, if drainage cannot be performed in time, the wound surface is slowly healed, the epidermis grows fast to form false healing, and finally anal fistula relapse is caused. On the other hand, pus on the wound surface can cause more serious inflammation and abscess, and the cleaning and changing of the medicine are victims of the patient, and the family members of the patient feel painful.

Chinese utility model patent specification CN 201880187U discloses a technical scheme with patent application number 201020647911.0, entitled "anal fistula and perianal abscess flushing drainage tube", and proposes that a hollow tube body and a tube head are made of hard polyvinyl chloride material and are connected in a terminating way; the tail part of the tube body is provided with a side hole, the middle part of the tube body is provided with a convex part and/or a concave part, and the head of the tube is provided with a convex part with a fixed position. When in use, the tube body part is inserted into the intestinal cavity of a patient, and the convex part and the concave part on the tube body play a role in fixing the flushing drainage tube in vivo. The convex part on the tube head is used for fixing the washing drainage tube outside the body to be connected with the washing equipment during washing.

However, such a rinsing drain also has the following disadvantages: 1, the hard tube head is exposed, and the patient can only lie on the side or in the prone position but cannot lie or sit flat. 2, the hard tube body is inserted into the body of a patient and is very uncomfortable.
