Multifunctional anorectal drainage tube

Abstract

The invention discloses a multifunctional anorectal drainage tube comprising a tube body. A main drainage passage tube is arranged inside the tube body and is provided with a drainage inlet and a drainage outlet. A bulb water-injecting passage tube is further disposed inside the tube body. A retaining elastic bulb and a locking fastener are disposed on outer wall of the front end of the tube body in order. The outer wall of the retaining elastic bulb is sleeved with a hemostatic dressing layer which is fixed on the tube body through the locking fastener. The outer wall of the front segment of the tube body is provided with a plurality of elliptical drainage pores; the drainage outlet of the main drainage passage tube is connected with a drainage bag; a sealing injection valve is disposed at the injection end of the bulb water-injecting passage tube. According to the multifunctional anorectal drainage tube, the retaining elastic bulb functions in internal fixation, the locking fastener functions in external fixation, separation rarely occurs, no contamination or damage occurs, long-term dwelling is available, and tube separation is avoided. The hemostatic dressing layer bulges along bulging of the retaining elastic bulb to allow drug hemostasis and compression hemostasis for an anorectal wound, recovery is promoted, and pain is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a multifunctional anorectal drainage tube. Background technique [0002] After hemorrhoid or anal fissure surgery, the patient's digestive function is weak, often accompanied by abdominal flatulence, and the stool is usually loose stool and watery stool. Because the excrement is highly irritating, the skin around the cavity is red, and in severe cases In the presence of eczema and varying degrees of inflammatory reactions, a large amount of gauze is usually placed in the anus for hemostasis and an anorectal drainage tube is placed for intestinal ventilation and drainage of dirt. [0003] Although the operation of placing a large amount of gauze in the anus is simple, when there is a lot of pus, the gauze needs to be replaced every day or at any time. Because the amount of gauze used is large, it takes a long time to replace the gauze, which will not only cause wound pain, but also make the pat...

AI Technical Summary

Problems solved by technology

[0005] 1. Easy to come out: there is no effective locking device to fix the drainage tube, so that the drainage tube is easy to slide inward and outward, and it is easy to come out;

[0006] 2. Easy to damage the intestinal tract: Since the self-made drainage tube is generally cut by itself, the cut surface is rough, the edges and corners are sharp, and a little excessive force can easily damage the intestinal tract and cause unnecessary infection;

[0007] 3. Difficult to care for: self-made drainage tubes have different diameters, and the length is cut with scissors according to the doctor's experience. It is not easy to fix in the anus, and generally it will not be left for a long time. Gauze is wrapped around the outside to prevent it from coming out, which makes it very troublesome to insert and take out the tube, and it is easy to be stained;

[0008] 4. There is no storage device, and the self-made drainage tube is not equipped with an interface connected to the storage device, and the outflowing dirt is easy to contaminate the bedding

[0009] 5. The function is single, and the self-made drainage tube can only be used for intestinal ventilation and drainage of dirt, and has no therapeutic effect on anal surgery
