Description
Technical Field
The invention relates to the field of electric field therapeutic instruments, in particular to direct-current low-frequency pulse rotating magnetic field therapeutic equipment.
Background
Electric field therapy has found much use in the treatment of cancer and other diseases in the last decade. Electric field therapy is delivered directly to the tumor lesion by low intensity, low frequency dc electrical pulses, where the electric field covers the cancer cells are "detonated" in two ways. First, in the metaphase of cancer cell division, the electric field affects the formation of spindle microtubules, resulting in abnormal chromosome segregation, which makes cancer cells unable to divide until apoptosis; second, at the end of cancer cell division, the electric field pushes charges towards the neck of the dividing cell, destroying the cancer cell structure, eventually leading to cell death. The two end results are the failure of cancer cells to divide normally, cell membrane blebbing and cell death.
Compared to normal cells, which have different electrical properties, electric field therapy does not cause much damage to normal cells because of the relatively high electrical conductivity and permittivity of tumor cells. Thus, tumor cells are relatively more sensitive to external electric fields than normal cells, especially gliomas.
The incidence of diabetes is much higher than that of cancer, so that electric field therapy is more significant for the treatment of hyperglycemia.
According to the traditional Chinese medicine meridian theory, after the magnetic field acts on meridian points of a human body, the biological effect of the human body can be adjusted, the activity of viscera cells can be improved, the autoimmune function and the repair capability can be enhanced, the metabolic disorder can be improved, the metabolic balance can be realized, and the pancreatic island function can be recovered.
Under the action of magnetic field, the saccharified hemoglobin can be stripped, the blood viscosity can be reduced, the metabolism of protein, sugar and fat can be regulated, and the metabolic balance of the organism can be realized. Meanwhile, the magnetic field can dredge qi and blood of channels and collaterals, activate cells, recover the functions of viscera, further improve terminal circulation and nerve transmission, and avoid various complications such as cardiovascular diseases, hyperlipidemia and the like.
Practice proves that the rotating magnetic field has better medical application and treatment effect on inhibiting diseases than a steady magnetic field. The direct current pulse electric field used for medical treatment has the general frequency within 100Hz and the magnetic induction intensity within 100Gs, and belongs to a safe magnetic field with low intensity and low frequency.
