Infant funnel type air bag anal tube sealing drainage device

Abstract

The invention discloses a funnel type air bag anal tube sealing drainage device for children, and relates to the technical field of medical instruments. Comprising a main pipe, an auxiliary pipe, an upper air bag and a middle air bag, the main pipe and the auxiliary pipe are concentrically arranged, the main pipe is rotationally connected into the auxiliary pipe, the upper air bag which is funnel-shaped after being inflated is arranged at the upper end of the main pipe, the middle air bag which is cylindrical after being inflated is arranged at the upper end of the auxiliary pipe, and the middle air bag is arranged on the lower side of the upper air bag. An elastic piece which is shrunk to be in a spring shape is arranged between the middle air bag and the upper air bag, the lower edge of the elastic piece is flush with the lower edge of the upper air bag, and the axial length of the elastic piece is larger than that of the upper air bag. The straight middle ring membrane on the outer side of the middle air bag is tightly attached to the rectum, the anastomosis area is compressed, the anastomotic stoma position is subjected to compression hemostasis, a rough material is arranged on the surface of the middle ring membrane, friction is increased, the anal canal drainage device is prevented from being disengaged, and the upper air bag at the front end of the pipeline is arranged to be in a funnel shape and is provided with an elastic piece with the length larger than that of the upper air bag.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a children's funnel-type airbag anal canal sealing and drainage device. Background technique [0002] The anal canal refers to the part from the dentate line to the anal verge, with an average length of 2.5cm for adults. The surgical anal canal refers to the part from the anal verge to the plane of the anorectal ring. The average length of an adult is 4 cm. The surgical anal canal has 4 boundaries; (1) the anal verge, usually also called the anal orifice, is the lowest boundary of the digestive tract; ( 2) The intersphincteric groove, that is, the white line, is between the anal verge and the dentate line, about 1cm away from the anal verge, just opposite the junction of the internal and external sphincter muscles. If you put your index finger into the anal canal, you can feel a recessed groove between the internal anal sphincter and the lower part of the external anal s...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the following technical problems exist in the anal canal drainage process in children at present: After anal surgery in children, in order to help the anastomotic stoma to heal and avoid anastomotic stoma contamination, anal canal drainage devices are often used. Funnel-shaped, the shape of the airbag is smooth after inflation. Even though the overall shape is funnel-shaped, the contact with the anal canal forms an arc, and there is still siltation. Although most of it is derived from the funnel shape, the siltation still occurs at the contact between the airbag and the anal canal Minor leakage causes unhygienic problems. Although minor leakage is better than the previous massive leakage, the leakage problem has not been completely solved. In addition, during the wound anastomosis process, tiny leakage will irritate the wound and delay wound healing
