Magnetic conducting iron sheets of the rotor component of the electronic motor are bonded with a ferrite permanent magnet according to forward magnetic pole to form an open magnetic path; the magnetic lines can be cut by a flat annular coil in a coil brace fixed on one end of a clamp plate when the rotor rotates in the copper clamp plate; and a transistor amplification circuit achieves magnetic driving to enable the magnet fixed on the rotor to generate a varying magnetic field in the body of a patient. The moving magnet therapeutic instrument has the advantages of small size, light weight, and long continuous work time when loaded with battery.

Description

Moving Magnetotherapeutic apparatus

Technical field

This utility model relates in healthcare field, drags the moving Magnetotherapeutic apparatus that permanent magnet block forms moving field for people provide a kind of based on electric motor.

Technical background

Magnetic therapy is meant with the action of a magnetic field in the method for human body with the treatment disease.In the Ancient Times in China medical literature with regard to useful magnetic pain relieving, treat the record of some disease.As far back as the Spring and Autumn and the Warring States Periods, well-known doctor Bian Que just is used to treat uterine prolapse outward with Magnetitum.Ming Dynasty's well-known doctor's Li Shizhen (1518-1593 A.D.) in Compendium of Material Medica, recorded and narrated with Magnetitum place Baihui acupoint treatment large intestine proctoptosis through the cave magnetic field therapy.In recent years, magnetic material and magnetotherapy appliance, magnetic therapy Study on Technology and application development are very fast both at home and abroad, obtain certain curative effect in the treatment of some diseases, and magnetic therapy becomes one of more general physiotherapy of application.

Experiment showed, that magnetic field energy influences synthetic decomposition and chemical reaction process, the metabolism of tissue and the function of histoorgan of the activity of the current potential of the inside and outside ionic mobility of biological cell, cell membrane, some enzyme, Cellular respiration, some material.Magnetic field can also influence some organism growing development and life.Magnetic field exerts an influence to the bioelectric current and the biological magnetic field of tissues such as people's nerve, muscle, the heart, lung, brain, and the interfering with pathological process is regulated the physiological equilibrium, promotes the recovery of normal function.According to the study, magnetic field can reduce the Irritability that teleneuron stimulates to external world, and the threshold of pain is raise, and plays analgesic activity.U.S. Skalak and Morris also find, use static magnetic field treatment when inflammatory damage immediately, can reduce blood vessel significantly and expand, and make inflammatory damage add quick-recovery.Effect calm, that improve sleep, relieve muscle spasms and bring high blood pressure down that magnetic field also has.Once there was the report high-intensity magnetic field to have and suppressed the effect that the carcinoma growth is shifted.

In China, the Magnetotherapeutic health articles for use of now having developed comprise magnetic belt, magnetic therapy pillow, magnetic mattress, magnetic therapy waistcoat, magnetic therapy shoulder protector, Magnetotherapeutic kneepad, magnetic therapy five elements' pin etc.Abroad, a kind of magnetic therapy bracelet was also once voguish.These Magnetotherapeutic health product all belong to magnetostatic therapy.They all are that one or more pieces permanent magnets are placed patient part or acupuncture point, treat with constant magnetostatic field, and method is simple.Yet magnetostatic therapy has tangible limitation.Some position of human body can the higher magnetic field of intensity issues the magnetisation adaptation or magnet fatigue affects the treatment because of long time is in, even illeffects.To this, all once developed the rotating magnetism therapeutic machine that moving field can take place both at home and abroad.2～4 samarium-cobalt alloy permanent magnets are arranged in the head of Magnetic rotator for medical freatment, drive, act on human body, can obtain analgesia effect preferably with moving field by miniature motor.In addition, also have to utilize pulsation or alternating current to produce pulsation or action of alternating magnetic field in the electromagnetic therapeutic apparatus of human body, also can overcome the defective in the magnetostatic treatment by handtailor coil.

Above-mentioned rotating magnetism therapeutic machine and electromagnetic therapeutic apparatus all exist not enough in practicality.At first, magnetic therapy is one needs the physical therapy method that the long period can obtain curative effect, but people expect a kind of long period and act on the varying magnetic field of therapentic part, the energy is relied on the proposition special requirement, need motor to drag permanent magnet as rotating magnetism therapeutic machine, electromagnetic therapeutic apparatus need be pulsed or the alternating current drive coil produces the method for varying magnetic field, all has limitation in practicality.Secondly, for the numerous crowds that require to carry out daily health caring, they more need a kind of portable and device little power consumption.In fact, electromagnetic therapeutic apparatus be that a stage body is long-pending, weight, the appreciable equipment of power consumption; Even rotating magnetism therapeutic machine adopts micromachine, its volume can satisfy portable requirement, but when its portable use, satisfies the requirement of supplying cell is difficult again.

The purpose of this utility model is to propose a kind of electric motor of little power consumption that utilizes and drags the Magnetotherapeutic apparatus that permanent magnet produces moving field, under the prerequisite that guarantees curative effect, satisfies requirement energy-conservation and portable in the magnetic therapy technology.
