Bias assembly and manufacturing method thereof, rotating bias field generating device and magnetotherapy instrument

Abstract

The invention provides a bias assembly and a manufacturing method, a rotating bias field generating device and a magnetotherapy instrument. The bias assembly is formed by splicing and fixing at least two permanent magnet units identical in magnetic induction intensity, the permanent magnet units are equal in length, the cross section of one of the permanent magnet unit is larger than that of the other permanent magnet unit, one end of each permanent magnet unit along the length direction is an N-electrode, and the other end is an S-electrode. The N-electrode of one of the permanent magnet unit is spliced with the S-electrode of the other permanent magnet unit through a splicing surface, and the S-electrode of one permanent magnet unit is spliced with the N-electrode of the other permanent magnet unit through a splicing surface. Magnetic fields of areas near two ends of the bias assembly are both N-electrode and S-electrode magnetic fields, one end is obvious in characteristics of the N-electrode magnetic fields, the other end is obvious in characteristics of the S-electrode magnetic fields, so bias fields are formed at areas of two ends of the bias assembly respectively, and targeted therapy on human bodies can be realized by the aid of the bias field.

Description

technical field [0001] The invention relates to medical equipment manufacturing technology, in particular to a bias magnetic assembly and its manufacturing method, a rotating bias magnetic field generating device and a magnetic therapy instrument. Background technique [0002] Studies have found that the magnetic field has a significant impact on the human body and other organisms. There are S poles and N poles in the magnetic field at the same time, and the two poles are in a balanced state. Experiments have proved that the S pole magnetic field and the N pole magnetic field have different biological effects. The N pole The magnetic field has a strong function of repairing cells, and the effects of oxidation, alkalization, activation, and excitement are obvious. The S pole magnetic field has the effect of promoting growth and accelerating photosynthesis. Rehabilitation treatment for various diseases, and the strong magnetic field of the S pole actively promotes the growth o...

Problems solved by technology

[0004] In the above-mentioned prior art, the therapeutic magnetic field provided by the magnetic field generating device for the subject includes both the N-pole magnetic field and the S-pole magnetic field, and the S-pole magnetic field and the N-pole magnetic field are generally balanced. However, most of the current magnetic flux therapy equipment The crowd has key needs, but both are indispensable. For example, some people need rehabilitation treatment, and the demand for negative magnetic field therapy is the focus. Some people need growth promotion treatment, so the demand for positive magnetic field treatment is the focus. In other words, it cannot meet the needs of these people, and cannot provide targeted treatment for the subject.
