Automatic medical temperature control colon cleansing device

Abstract

The invention provides an automatic medical temperature control colon cleansing device which comprises a power circuit, a power drive circuit, a heater and a thermistor which are all electrically connected. A test probe of the thermistor stretches into the heater. The automatic medical temperature control colon cleansing device further comprises a single chip microcomputer connected with the power drive circuit in a control mode. The two ends of the thermistor are connected to a same-direction input end and a reverse-direction input end of an operational amplifier respectively. An output end of the operational amplifier is connected to a voltage signal acquisition pin of the single chip microcomputer. An output duty ration pin of the single chip microcomputer is connected to the power drive circuit. The heater is powered to heat liquid and raises the temperature of the liquid. The resistance value of the thermistor changes along with changes of the temperature of the heater. The resistance value changing along with changes of the temperature is converted into a voltage value and the voltage value is then amplified and converted. The power loaded on the heater is controlled and adjusted according to the processing result so as to adjust the temperature of the liquid, and the purposes of automatic detection and temperature control are achieved; meanwhile, the acquired voltage signals are more accurate through introduction of the digital acquisition technology, and temperature control accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of automatic control of medical equipment, and in particular relates to a medical automatic temperature-control bowel cleanser. Background technique [0002] Medical bowel cleanser, also known as hydrotherapy device, hydrotherapy device, enema device, etc., is used to insert liquid into the colon from the anus with the help of the anal canal to achieve the purpose of defecation and waste removal. The injected liquid can stimulate intestinal peristalsis, soften it, and facilitate defecation. , and have the effects of cooling, inducing labor, diluting intestinal poisons and reducing absorption. In addition, it can also achieve the purpose of supplying drugs and nutrition. During use, according to different patients, liquids such as medicine, nutrition, and water can be injected into the anal canal.

AI Technical Summary

Problems solved by technology

During use, according to different patients, liquids such as medicine, nutrition, and water can be injected into the anal canal. In order to reduce the patient’s discomfort or achieve the best action temperature of the medicine, it is necessary to pre-heat the liquid entering the anal canal. Existing medical sausage enema machines do not have an automatic temperature control function, and cannot accurately control the temperature of the heating liquid. Too high or too low liquid temperature will cause strong discomfort to the patient, and even endanger safety. Too low temperature is not conducive to the efficacy of some drugs. At the same time, patients of different ages and signs have different discomforts to liquids with slight temperature differences in the body. Due to the lack of automatic temperature control function, the development of existing sausage enema machines is hindered when they meet the needs of different patients.
