Medical enema machine capable of automatically adjusting pressure

Abstract

The invention provides a medical enema machine capable of automatically adjusting the pressure, which comprises a power supply circuit and a speed regulating air pump, wherein the power supply circuit is provided with a first power supply output end and a second power supply output end, the speed regulation air pump is connected with the second power supply output end, the first power supply output end and the second power supply output end are connected through a photoelectric coupler, and a pressure regulating circuit is connected between the second power supply output end and the speed regulating air pump. The medical enema machine is characterized by further comprising a singlechip microcomputer and a pressure sensor which are electrically connected, wherein the output end of the pressure sensor is connected with a pressure signal acquisition pin of the singlechip microcomputer, and an output duty ratio pin of the singlechip microcomputer is connected with the pressure regulating circuit. According to the invention, the speed regulating air pump is electrified and operates so as to improve the pump-in or pump-out pressure, the pressure sensor acquires pressure in the anal canal in real time, the acquired pressure is processed by the singlechip microcomputer, and the operating state of the pressure regulating circuit is controlled according to a processing result, so that an average voltage value loaded on a speed regulating air pump brushless motor is regulated so as to regulate the average rotating speed of the brushless motor, and thus the flow of the speed regulating air pump is regulated, thereby achieving the purposes of automatic detection and automatic pressure regulation.

Description

technical field [0001] The invention belongs to the technical field of automatic control of medical equipment, and in particular relates to a medical sausage enema machine with automatic pressure regulation. Background technique [0002] Enema machine enema method is to use the anal canal to insert liquid into the colon from the anus through the rectum to achieve laxative and exhaust treatment. It can stimulate intestinal peristalsis, soften and remove feces, and has the effects of cooling, urging labor, diluting intestinal toxins, and reducing absorption. In addition, it can also achieve the purpose of supplying medicine, nutrition, water and other treatments. The anal canal can be used to inject liquids such as medicines, nutrients, and water into the colon, and to inflate the colon. At the same time, the waste in the colon can also be discharged through the anal canal. The substances are injected or discharged from the colon through the anal canal at both ends of the anal...

AI Technical Summary

Problems solved by technology

The anal canal can be used to inject liquids such as medicines, nutrients, and water into the colon, and to inflate the colon. At the same time, the waste in the colon can also be discharged through the anal canal. The substances are injected or discharged from the colon through the anal canal at both ends of the anal canal It is achieved by pressure difference. When the external pressure is high, liquid or gas is pressed into the colon. When the pressure in the human body is high, the waste in the colon is discharged. In order to reduce the discomfort of the patient, or to inject or discharge the substance smoothly, When the sausage enema machine is used for different purposes, it is necessary to adjust the pressure value of the external end of the anal canal. The existing medical sausage enema machine does not have the function of automatic pressure regulation, and cannot accurately control the work of the pump. Too high or too low pressure values ​​will cause patients to have Strong discomfort, even endangering safety; at the same time, patients of different ages and signs have inconsistent discomfort caused by subtle differences in the speed of substances entering or exiting the body. Development is hindered when addressing different patient needs
