Abstract

The invention discloses a multi-channel mixed signal acquisition system for medical rehabilitation equipment. The system comprises eight analog sensors, a digital sensor, a voltage acquisition circuit, a pre-amplification circuit and a central processing unit, wherein the analog sensors are used for detecting pressure of wrist joints of two hands, elbow joints, shoulder joints and hands respectively and outputting eight corresponding voltage signals in real time; the digital sensor is used for detecting the rate of the heart and outputting corresponding electrocardio pressure signals in real time; the voltage acquisition circuit collects eight voltage signals and converts the voltage signals into one input signal ADC; the central processing unit receives an input signal DOUT and the input signal ADC and form one serial data for transmission. The system is mainly applied to accurate signal acquisition of the medical rehabilitation equipment in the medical rehabilitation field, realizes simultaneous and real-time acquisition of multiple signals, achieves the purpose of measurement of complicated signals and mixed measurement of multiple signals and also facilitates real-time display on an upper computer.

Description

technical field [0001] The invention relates to a medical rehabilitation device in the medical field, in particular to a multi-channel mixed signal acquisition system for the medical rehabilitation device. Background technique [0002] With the acceleration of the aging process in China, the health problems of more and more elderly people have gradually become social problems. Stroke is a common disease among the elderly. It has the characteristics of high morbidity, high mortality and high disability rate. , a serious threat to the health of the elderly. Stroke is an important factor leading to patients with hemiplegia. Hemiplegia can directly cause the gradual loss of the patient's motor function and daily life self-care ability, which has a serious impact on the patient's quality of life. Therefore, a lot of medical rehabilitation equipment has appeared to help the elderly with rehabilitation treatment. In the medical rehabilitation equipment, many sensors are needed to ...
