Description

A kind of modified model low frequency rotates strong permanent magnetic field treatment device

Technical field

The present invention relates to a kind of low-frequency magnetic therapy device, relate in particular to a kind of modified model low frequency and rotate strong permanent magnetic field treatment device.

Background technology

Discover that all there is tangible influence in magnetic field for human body and other biology, water or chemical agent, the rotating excitation field that present permanent magnet provides mostly adopts a pair of utmost point or many to electrode structure, will be subjected to magnet to be placed on a pair of utmost point or many centres to utmost point permanent magnet.The magnetic field (as shown in Figure 1, 2) that the permanent magnet of placing in the above described manner produces is its inside of magnetic field uniformly penetrating to being subjected to magnet, or magnetic field can only act on its superficies, and reason is: the one, the magnetic field no change is little to the effect that is subjected to magnet; The 2nd, can't carry out magnetic field therapeutic to being subjected to a certain position of magnet; The 3rd, permanent magnet produces the magnetic line of force to be disperseed.Therapeutical effect is not fairly obvious in a word.

The magnetic field therapy apparatus that Chinese patent 88216746.4, name are called " electronic magnetic field therapy apparatus " to be provided can only act on the part on the human body, such as the acupuncture point, inside of human body is deep to internal organs then acts on not quite.Trace it to its cause is that the permanent magnet volume is big inadequately.Chinese patent 97116885.7, name are called " a kind of gyro magnetic magneto therapeutic bed " to be provided by the lathe bed that has fixed bed surface and has been positioned at the bed body that this fixed bed surface bottom, reciprocating mobile bed surface constitute, at least two Magnetic rotator for medical freatment are installed in this mobile bed surface upper surface, the disk upper surface of this Magnetic rotator for medical freatment and fixed bed surface following adjacent, the magnetic line of force that the magnetic field that this patent provided produces disperses, and therapeutic effect is limited.Chinese patent 93118017.1, the magnetic field therapeutic device that the permanent magnet low frequency that name is called " a kind of low frequency rotation permanent magnetic field therapeutic device " provides a kind of degree of depth to infiltrate rotates, it fixes the pedestal that a permeability magnetic material is made on flat board, intrinsic at least two permanent magnets that the dividing plate made from non-magnet material separates on the described pedestal, fix at least one cartridge on the outer surface of permanent magnet respectively, fix a high-coercive force permanent magnet between adjacent two different in nature permanent magnets, the magnetic direction of this high-coercive force permanent magnet is opposite with the formed magnetic direction of magnetic circuit that constitutes of cartridge with permanent magnet on it with described pedestal.Weak point is the trapezoidal or rectangle that the shape of permanent magnet mostly is rule, and magnetic field intensity is subjected to the influence of volume, face area, magnetic flux change of permanent magnet bigger, and its useful effect degree of depth and effective range are limited; The mechanical part of Magnetotherapeutic apparatus is connected with reducer of turbodrill by motor, drives the output shaft rotation, complex structure, during running vibrations bigger, noise is higher, and patient's therapeutic effect is influenced to some extent.

For overcoming the defective of the above prior art, and the present invention is proposed.

Summary of the invention

The present invention has overcome the prior art deficiency, provides that a kind of magnetic field intensity is big, simple in structure, noise low (less than 50 decibels), modified model low frequency that the permanent magnet speed is adjustable rotate strong permanent magnetic field treatment device.

In order to solve the problems of the technologies described above, the present invention adopts technical scheme to be: be provided with support on the base plate of horizontal positioned, vertical machine and power transmission shaft are arranged on the corresponding support, this power transmission shaft is vertically placed, this motor output shaft head is provided with small pulley, drive the big belt wheel that is fixed on the power transmission shaft by transport tape, the upper end of described power transmission shaft is connected with flat board suitable at along continuous straight runs or that be rotated counterclockwise, this flat board is provided with conductive magnetic yoke, described conductive magnetic yoke is provided with at least two permanent magnets that separate with dividing plate, this dividing plate is that non-magnet material is made, be arranged on the conductive magnetic yoke surface in the groove with its coupling, the outer surface polarity of adjacent permanent magnet is opposite, fixes the head that at least one block of permeability magnetic material made on the permanent magnet outer surface respectively, fixes a high-coercive force permanent magnet between adjacent two permanent magnets; Described control section comprise the employing infra-red remote control motor that is arranged on the base plate startup, stop, the controller of speed governing, control unit interface connects computer, computer is connected with printer.

The big belt wheel upper end of described power transmission shaft is provided with two identical bearings, and the lower end is provided with a bearing.The upper end bearing is a taper roll bearing, and the lower end is a cylinder roller bearing.

Described conductive magnetic yoke is a rectangle, and four limits are provided with chamfering (as Fig. 6), and chamfering is rectangle or square, and the cross section that makes conductive magnetic yoke is irregular rectangle, increases the variation of magnetic flux.

Groove on the described conductive magnetic yoke and dividing plate number are complementary, and described groove can be dovetail groove, straight trough or U-lag.

Described permanent magnet is the permanent magnet of the area adjustable size that rearranges of some little magnet steel, the particularity of this permanent magnet and special construction, the high-intensity magnetic field of 0.5-1.2T can be provided, and the effective depth of the infiltration in magnetic field can reach 500 millimeters, and the effective range diameter can reach 950 millimeters.

Described permanent magnet can be made for superconductor.

The ultimate principle that this modified model low frequency rotates strong permanent magnetic field treatment device realization is to drive the permanent magnet rotation by motor rotation to produce magnetic field, thereby constitutes the operative configuration of whole Magnetotherapeutic apparatus.Its conductive magnetic yoke cross section of described permanent magnet is irregularly shaped, and this special construction makes permanent magnet produce more diverse magnetic flux when rotated, and the magnetic line of force that described rotating excitation field produces is penetrable or infiltrate the effect that health plays the dark internal organs of magnetic therapy.

The present invention also has following beneficial effect except that for having the effect of good alleviation and elimination such as the pain among late period patient's internal organs such as osteocarcinoma disease:

(1) sclerotin is dredged disease: can alleviate or eliminate the pain that is caused by osteoporosis, treat more than 15 times continuously, can improve in a short time and increase so density also can be safeguarded 1-2.

(2) femur head necrosis: all effective to osteonecrosis of femoral head excessive owing to hormone or that other reason causes.

(3) aplastic anemia: chronic or acute aplastic anemia is had certain curative effect.

(4) drug rehabilitation: improve the drug abstainer sleep, make it can reach the purpose of drug rehabilitation more smoothly.
