Anal expansion device for pediatrics

Abstract

A pediatric anal expansion device includes a body, a piston, a stopper rod and a plurality of sleeves, the plurality of sleeves are sleeved together, the plug rod is sleeved in the innermost sleeve, and the plurality of sleeves are slidably arranged in the body. The body includes an outer sleeve, a lubricating oil storage cylinder and a fixed sleeve, and a liquid storage chamber is arranged in the lubricating oil storage cylinder. A plurality of liquid outlets are arranged on the outer casing, and the liquid outlets are connected with the liquid storage cavity, and a channel is arranged in the outer casing, and the outermost casing is arranged in the channel. The rear end of the outer sleeve is provided with a fixed sleeve, and a number of guide holes are evenly distributed in the fixed sleeve, and corresponding marks are provided at the guide holes. U-shaped push rods are arranged at the rear ends of the plug rod and the sleeve pipe, and the ends of the push rods are arranged in corresponding guide holes. The piston includes a sealing plug, a push plate and several connecting columns, the connecting columns are arranged between the sealing plug and the pushing plate, and the sealing plug is arranged in the liquid storage chamber. The invention prevents children from suffering the pain of continuous insertion and extraction when the anus is gradually expanded; the plug rod can be automatically heated to a suitable temperature to avoid over-stimulation of the anus; the anus can be timed and sounded to prevent the anus from being too long.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a pediatric anal expansion device. Background technique [0002] In pediatrics, infants and young children who are congenitally without anus need to undergo surgery to reconstruct the anus. The newly created anus needs to be expanded with different anus expanders every day to exercise the contraction ability of the anus. When expanding the anus, the child suffers a lot and the sphincter is not enough Relaxation, the anal expansion action should be gentle, and the anus should not be opened violently and quickly, otherwise it will easily cause multiple tears of the mucous membrane and anal canal, and symptoms of anal canal tearing will also occur. The currently used anal dilator is composed of a group of metal round rods with different diameters. The disadvantage of this anal dilator is that the round rods need to be replaced many times. The operation is very tr...

AI Technical Summary

Problems solved by technology

The currently used anal dilator is composed of a group of metal round rods with different diameters. The disadvantage of this kind of anal dilator is that the round rods need to be replaced many times. The operation is very troublesome, time-consuming and laborious, and increases the difficulty of work for medical staff

At the same time, these metal round rods are too cool, and after being inserted into the anus, it is easy to stimulate the anus of the child, stimulate the anus to contract, not relax enough, and make the child feel uncomfortable

There are also inflatable anal expanders, but the effect of the inflatable anal expander is not ideal. When the anus is forced to contract, it is easy to squeeze and deform the inflatable anal expander, and the effect of anal expansion cannot be achieved.
