Control circuit of medical nutrient solution heater

Abstract

The invention relates to the field of medical instruments, in particular to a control circuit of a medical nutrient solution heater. According to the control circuit of the medical nutrient solution heater, the temperature of a nutrient solution is kept constant at about 37 DEG C, the temperature adjustment can be achieved without switching on or off the heater, and the medical nutrient solution heater control circuit is extremely convenient to use. The control circuit of the medical nutrient solution heater comprises a thermistor, a comparator module, a temperature detection module and the like, the output end of the thermistor is connected with the input end of the comparator module, and the output end of the comparator module is connected with the input end of the temperature detectionmodule. According to the invention, the thermistor is used for temperature control, and the comparator module, the temperature detection module and the relay driving module are combined to keep the temperature of the nutrient solution at about 37 DEG C and keep the temperature constant, so that the nutrient solution can be normally infused in cold seasons or environments, and the discomfort of a patient caused by the nutrient solution is reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a control circuit for a medical nutrient solution heater. Background technique [0002] There are many kinds of medical nutrient solutions, and the basic components are basically the same, including amino acids, fatty acids, vitamins, essential minerals, etc. The specific use can be adjusted according to the current physical condition, but generally it has a certain effect on maintaining nutrition and physiology. Nutritional therapy began to use it for treatment, such as ketogenic diet for epilepsy, diet treatment for diabetes, etc. Understanding the role of food as the body's basic source of energy and various nutrients, according to its role in food preparation, can help maintain the health of patients and reduce complications and chronic diseases. When used in winter, because the temperature of the infused nutrient solution is lower than the body temperature of the human body...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortcoming that the current temperature of the nutrient solution cannot be seen when the nutrient solution is heated, it is easy to cause the overheating of the nutrient solution. Therefore, the technical problem of the present invention is: to provide a method that can keep the temperature of the nutrient solution at about 37°C without switching the heater. To achieve temperature adjustment, it is very convenient to use the medical nutrient solution heater control circuit
