Abstract

The invention relates to the field of medical instruments, in particular to an internal temperature and humidity control circuit of medical equipment. The technical problem to be solved is to provide a medical equipment internal temperature and humidity control circuit which is convenient to use and high in safety. According to the technical scheme, the internal temperature and humidity control circuit of the medical equipment comprises a power supply unit, a second comparator circuit, a heating circuit, a temperature detection circuit, a reverse proportion operation amplification circuit, a first potentiometer, a temperature sensor and a temperature adjusting potentiometer, and the first potentiometer is connected with the input end of the temperature detection circuit; and the output end of the temperature sensor is connected with the input end of the temperature detection circuit. Through cooperation of the temperature sensor and the heating circuit, the internal temperature of the medical equipment can be detected, and when the internal temperature of the medical equipment is low, the interior of the medical equipment can be automatically heated, so that the internal temperature of the medical equipment is always kept within a certain range.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a temperature and humidity control circuit inside the medical equipment. Background technique [0002] The normal operation of medical equipment is based on certain temperature and humidity conditions. If the environmental temperature and humidity conditions cannot meet the stability of medical equipment, the safety will be affected, and even cause failures that endanger the safe operation of medical equipment, and different equipment needs to be in different locations. temperature and humidity conditions. [0003] In terms of current technology, it is usually necessary for medical staff to manually control the startup and shutdown of heaters and fans, so as to keep the temperature and humidity inside the medical equipment within a certain range, which is troublesome, error-prone, and not very safe. Therefore, a convenient and safe internal temperature and humidity control circu...
