Artificial fistula plugging device

Abstract

The invention provides an artificial fistula plugging device. The artificial fistula plugging device comprises a plugging opening and an intestinal inner wall clamping pipe, wherein the plugging opening is of an annular structure with a contraction hole in the middle; a defecation channel is formed in the intestinal inner wall clamping pipe; the plugging opening is fixedly connected with the intestinal inner wall clamping pipe; a clamping air bag communicates with an inflation hole through the plugging opening and a channel formed in the intestinal inner wall clamping pipe; extrusion connecting rods are movably inserted into open grooves in the upper end and the lower end of the side wall of the plugging opening; and the movable ends of second extrusion springs on the two sides are fixedly connected with a closed clamping ring through second extrusion pistons. According to the artificial fistula plugging device, the action of the sphincter of the normal human body is simulated through a contraction ball bag, so that the artificial fistula is assisted to carry out autonomous controllable defecation, a plugging plug in the prior art does not need to be repeatedly inserted and pulled in the opening process, excrement overflow is effectively prevented, and the probability of inflammation caused by infection around the stoma can be greatly reduced by injecting antiviral gel and other medicines into a medicine coating hole through a medicine injection hole at regular intervals.

Description

technical field [0001] The invention relates to the technical field of anorectal medical devices, in particular to an artificial fistula occluder. Background technique [0002] In the prior art, the application number is "CN201310400113.6", an artificial anus device with blocking and intestinal sphinctering functions, including a magnetic ring and a blocking plug. The blocking plug is composed of a metal core part and a shell. The magnetic ring is connected by magnetic beads, and the adjacent magnetic beads are connected by an independent "I" type titanium connecting element. The magnetization direction of the magnetic core in the magnetic beads points to the center of the circle. The device provides an artificial anus The application of the device has the advantages of small pressure on the intestinal tube and uniform force, reducing the possibility of intestinal ischemic necrosis; it is not easy to break down, and the implantation method is simple and minimally invasive; t...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned artificial anus device with blocking and intestinal sphincter still has obvious defects during use: 1. The above-mentioned device simulates the function of the sphincter through the repulsion and adsorption principle of the magnet, but the above-mentioned device is in use. It needs to be manually inserted and pulled out to complete the release of feces. Since the plug-in port is also used as a discharge channel for feces, during the pull-out process, if the connection of the feces bag is not timely, it may easily cause feces to overflow and affect the user experience; 2. Due to artificial fistula Stoma infection and inflammation often occur in the mouth and affect the healing of the stoma. The above-mentioned devices and skin contact parts have not been effectively treated with antibacterial and anti-inflammatory agents. During long-term use, the inflammatory response of the stoma is likely to aggravate and affect the normal use of the device.
