Abstract

The invention relates to the field of medical treatment, and in particular, relates to a medical headrest control circuit. The invention aims to provide the medical headrest control circuit which can promote blood circulation of a patient and increase the rehabilitation speed of the patient. According to the technical scheme, the medical headrest control circuit comprises a temperature sensor, a temperature comparison and amplification circuit, a power supply unit, a hysteresis comparator control circuit and the like. The temperature sensor is connected with the input end of the temperature comparison and amplification circuit, and the output end of the temperature comparison and amplification circuit is connected with the input end of the hysteresis comparator control circuit. Through cooperation of the temperature sensor and electrothermal film carbon fibers, a headrest can be kept at a proper temperature, so that blood circulation of the patient can be promoted, and the rehabilitation speed of the patient is increased; and the reference temperature of the temperature comparison and amplification circuit can be adjusted under the action of a constant-temperature potentiometer, so that the circuit can be suitable for different patients.

Description

technical field [0001] The invention relates to the medical field, in particular to a medical headrest control circuit. Background technique [0002] Headrest is a kind of medical device, which is used to support the patient's neck, so that the patient can have a good sleep quality and make the patient energetic during the day, but most of the headrests are relatively simple in structure now, without heating Function, can not promote the patient's blood circulation, can not speed up the patient's recovery, so design a medical headrest control circuit that can promote the patient's blood circulation, can speed up the patient's recovery. Contents of the invention [0003] In order to overcome the shortcomings that most of the current headrests are relatively simple in structure, have no heating function, cannot promote the patient's blood circulation, and cannot speed up the patient's recovery speed, the technical problem of the present invention is: to provide a headrest th...
