A dual output thermal medium and low frequency therapeutic apparatus with self-checking function

Abstract

The invention discloses a double-path warm middle-low frequency therapeutic instrument with a self-checking function and an implementation method. The double-path warm middle-low frequency therapeutic instrument comprises a first controller, a second controller, an A-path output system, a B-path output system, an input and output module and a self-checking system; the first controller is a master controller, controls the operation of the system, and monitors whether a loop is formed between two electrode plates of the A-path output system or the B-path output system in real time, and performs judgment; the second controller is a slave controller and provides modulation waveforms for the A-path output system and the B-path output system, the modulation waveform output of the second controller being controlled by the first controller; the self-checking system is connected with and communicates with the first controller and is used for detecting whether the system is normal; the A-path output system and the B-path output system are controlled by the first controller and modulates PWM waves outputted by the first controller so as to obtain prescriptive waves and outputs the prescriptive waves to the electrode plates, and feeds back the waveform voltage and temperature of the electrode plates to the first controller through a sampling circuit.

Description

technical field [0001] The invention relates to the field of therapeutic instruments, in particular to a dual-channel output warming medium-low frequency therapeutic instrument with a self-checking function. Background technique [0002] Chinese acupuncture and massage are one of the very important disease treatment methods in medical physical therapy. Chinese acupuncture and moxibustion include acupuncture and moxibustion. Stimulate to treat disease. Traditional Chinese massage stimulates the body's lymph, joint nerves, muscles, blood vessels, and skin through physical techniques such as pressing, rubbing, pushing, holding, kneading, and rubbing, and improves the body's immunity through physical techniques. However, both require a long course of treatment and relatively professional TCM physicians to implement treatment, which is difficult to meet the actual needs of the broad masses of the people. And with the development of society and the improvement of human health aw...

Problems solved by technology

[0003] In addition, in order to cope with the current extensive and fierce market competition, the sales profit of therapeutic devices used in home medical care is generally low. Although the therapeutic devices have carried out relevant output testing before leaving the factory, most consumers do not understand the product characteristics and operate improperly. , fail to achieve the desired results, and often mistakenly believe that the product has quality problems, which increases the after-sales burden, resulting in a decrease in product gross profit and easily damaging the manufacturer's brand reputation
