Laser acupuncture and moxibustion therapeutic instrument based on PID control

Abstract

The present invention discloses a laser acupuncture therapeutic equipment based on PID control. It is characterized by that the light-sensing diode can be used for converting output power of semiconductor laser into equiproportional current signal, after the current signal is passed through light power monitoring circuit, said current signal is converted into equiproportional voltage signal, then the voltage signal can be transferred into A / D convertor to make A / D conversion; the converted digital signal and specified value are formed into control deviation, a chip computer is used to make PID control operation to form a control quantity; after the digital signal is passed through the D / A convertor, it can be used for controlling drive current of LD so as to control laser power to implement reinforcing and reducing by lifting and thrusting the needle of acupuncture therapy.

Description

technical field [0001] The present invention is a medical instrument invented by combining traditional Chinese medicine acupuncture theory and practice with modern instrument science and technology. It uses MSP430 single-chip microcomputer as the control platform, integrates classic PID control theory into laser diode power control, and introduces chaos mathematical model method to realize Realize the simulation of new dynamic, deep and easy-to-control moxibustion methods, and can realize the most basic acupuncture-reinforcing and reducing techniques in traditional Chinese medicine and the semiconductor laser acupuncture-moxibustion therapeutic instrument. Background technique [0002] The research and development of modern acupuncture and moxibustion treatment instruments have gradually embarked on the road of development and integration of modern science and technology, especially on the basis of traditional Chinese medicine theory, combined with computers, microelectronics...

AI Technical Summary

Problems solved by technology

However, there are still shortcomings and deficiencies in various laser acupuncture instruments at present: the simple irradiation method of certain wavelength laser acupuncture, such as He-Ne laser acupuncture instruments, etc., adopts continuous direct irradiation, which is the simplest working method , the treatment is also the simplest, but it is extremely single in terms of treatment methods and acupuncture techniques, lacks flexibility, and cannot realize the extensive and profound acupuncture theory of traditional Chinese medicine. However, pulsed laser irradiation is used to improve this. Simple electronic circuits can output simple However, in general, this method can only simply simulate the simplest acupuncture technique in traditional acupuncture, and it cannot achieve the combination of acupuncture and moxibustion effects. Usually, this kind of signal also exists Disadvantages of being easily adapted by the human body

At present, there are many acupuncture and moxibustion treatment instruments on the market, most of which have output signals that do not meet the dynamic requirements. not yet implemented
