Description

hemostatic anal drainage tube

technical field

The utility model relates to the field of medical devices, in particular to provide a hemostatic anal canal drainage tube used after hemorrhoidal mucous membrane circular excision and stapling (PPH)

Background technique

At present, oily gauze, cotton wool, air bag, water bag or anal canal drainage tube are generally used to compress the wound to stop bleeding after clinical PPH in the anorectal department. But the oppression of oil gauze or cotton wool is not thorough, it is easy to move and fall off, and it will cause poor exhaust and defecation, and it is easy to cause symptoms such as abdominal distension, abdominal pain, and dysuria. The air bag or water bag is made of hard material. It is difficult to control the amount of air or water in clinical use. If the pressure on the wound is too light, the hemostatic effect will not be achieved. If the pressure is too high, it will cause local ischemia of the wound. lead to local tissue necrosis. The small diameter of the anal canal drainage tube is not conducive to drainage. Due to its small elasticity, it affects the blood supply of the wound and is not conducive to healing. Due to its hard texture, it is easy to produce greater physical stimulation to the anastomotic wound during extubation, increasing the chance of anastomotic bleeding .

In January 2013, an article titled "Application of Self-made Anal Canal Drainage Tube Connected to Drainage Bag in PPH Operation" in Shandong Medical Journal disclosed a self-made anal canal drainage tube connected to drainage bag device. The tube drainage tube is connected to the drainage bag device to fill the anal canal. It is a rubber tube with a length of about 30 cm, with 2 to 3 side holes cut at the head end, wrapped with dilute iodophor and Vaseline gauze, and fixed with silk thread. One side hole is exposed at the head end, and a common drainage bag is connected at the end end. On the first day after the operation, the drainage tube was flushed with normal saline and observed for bleeding, and the anal canal packing was removed on the second day after the operation.

The disadvantages of this method are:

1. The self-made anal canal drainage tube used in the research is a rubber tube, because it is softer than the latex tube, and it is easy to be compressed by the tissue and collapse, and the drainage tube used is small in diameter, and it is easy to be blocked by feces, which is not conducive to drainage.

2. The content wrapped by vaseline gauze has poor elasticity, and the degree of oppression on the anastomotic stoma does not change with time, which can cause a decrease in blood supply at the anastomotic stoma, which is not conducive to healing; because the material wrapped by vaseline gauze is relatively hard, when extubation It is easy to produce greater physical stimulation to the anastomotic wound and increase the chance of anastomotic bleeding.
