Description

Medical enema device of relaxing bowels

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a medical enema and bowel relaxing device.

Background

Intestinal obstruction patients adopt enema treatment, and an auxiliary treatment method is relatively commonly used in clinic. The enema treatment is to insert a large amount of liquid or medicine from anus through rectum into colon by using a catheter, which can stimulate intestinal peristalsis, soften and remove faeces, has the functions of reducing temperature, hastening parturition, diluting toxic substances in intestines and reducing absorption, and can achieve the treatment purposes of supplying medicine, nutrition, moisture and the like so as to treat constipation and enteritis type diseases.

At present, when a clinical nurse performs an enema operation, as shown in fig. 1, a liquid storage tank 1 of an enema device is hung on an infusion support 2, the bottom of the liquid storage tank 1 is connected with an intestinal canal 3, a balloon 4 is arranged on the intestinal canal 3, and liquid in the tank is injected into a colon by self gravity or a mode of squeezing the balloon 4; in the treatment process of different diseases, medicines are added into the liquid storage tank 1, and the medicines are injected into the colon together with the liquid in the tank, so that the treatment purpose is achieved.

In the operation process of the traditional enemator, the balloon 4 is required to be continuously extruded, and the principle is that when the balloon 4 is extruded, the balloon 4 is deformed, the inner cavity space of the balloon 4 is collapsed, and the liquid in the balloon 4 and the intestinal canal 3 is pressed into the colon; after the pressure is released, the balloon 4 restores the inner cavity space through the deformation memory of the balloon wall, negative pressure is formed in the inner cavity, and the liquid in the liquid storage tank 1 is sucked into the balloon 4 to wait for the next extrusion of the balloon 4.

In practical application, after the balloon 4 releases pressure, the negative pressure in the balloon 4 can not only promote the liquid in the liquid storage tank 1 to enter the balloon 4, but also suck the turbid liquid in the colon backwards, so that the intestinal canal 3 is polluted; and the balloon 4 is continuously extruded by manpower during the clysis, which is very laborious. How to prevent the back suction of the enemator and save more labor during the enema is an important point for those skilled in the art to pursue continuously.
