Problems solved by technology

The condition of the equipment at work and the spatial distribution of the magnetic force lines generated by it are as follows: figure 1 It can be seen from the figure that the irradiated patient is exposed to the magnetic field in a large area, and the angles at which the magnetic field lines enter the various parts of the human body and the field strengths of the irradiated parts of the patient are different. Obviously, the existing This kind of permanent magnet gyromagnetic device has the following problems: 1) the target area is not clear during the use of the device, the field strength of each point of the patient's irradiated part is not equal and uncontrollable, and the directions of the field vectors of each point of the patient's irradiated part are different, so , although in clinical use, it is effective for some indications, but it is only some macroscopic results, and it does not indicate where, how strong, and what form of magnetic field acts on the patient. As this kind of equipment can no longer be further improved and developed, this situation needs to be improved urgently; 2) the magnetic stack is too large in size, high in cost, and high in cost; Excessive magnetic leakage is generated during use, which brings magnetic pollution to a large area around; 4) Excessively large magnetic stacks rotate at high speed during use, posing safety hazards

Abstract

The invention discloses a permanent magnet gyromagnetic apparatus, which is used in the time-varying magnetic field field and particularly suitable for the medical treatment and rehabilitation field. The permanent magnet gyromagnetic apparatus comprises four permanent bar magnets which are respectively arranged on four corners of a quadrangle, wherein, a target area is formed in the quadrangular area. The permanent magnet gyromagnetic apparatus has the advantages of definite target area, measurable single magnetic field, small magnet volume, safe operation, selectable field density and knowable field form, and fundamentally solves the problem that the prior apparatus can not be further improved and developed and overcomes the technical difficulty with bottleneck property in the magnetic medical treatment field.

Description

[0001] Field [0002] The invention discloses a permanent magnet gyromagnetic device, that is, a variable magnetic field generator using permanent magnet materials as a magnetic source, which is used in the field of magnetic fields that need to change with time, and is especially suitable for the fields of medical treatment and rehabilitation. The magnetic field it generates can be used in occasions that require a time-varying magnetic field environment and special mechanical behavior, especially the magnetic field it generates is used to irradiate specific parts of the human body to achieve the purpose of treatment or rehabilitation, and is especially suitable for Treatment of human pain, relief of muscle fatigue, improvement of microcirculation system, etc. Background of the invention [0003] There are two ways to generate a magnetic field. One is to use a energized coil, and the other is to use a permanent magnet as a magnetic source. The former has the disadvantages of he...
