Abstract

The invention provides an electromagnetic generating device with adjustable frequency band and its electromagnetic generating method. From the perspective of spectrum analysis and quantum mechanics, a possible mechanism of the frequency window of the biological effect of pulsed electromagnetic field is given, and the biological effect of pulsed electromagnetic field is obtained through quantitative calculation. The frequency domain window of the effect, and then, based on this theory, an electromagnetic field generator for determining the frequency window of the pulsed electromagnetic field biological effect was developed. The device is mainly composed of a white noise signal generator module, a filter module, a gain adjustment module, a power amplifier module and a magnetic field generator Composed of modules, the output includes the resonance frequency bands of the main nucleons 1H, 13C, 14N, 17O, 23Na, 31P in the organism, and according to the needs, the pulsed electromagnetic field with a variable frequency range is output, and this device is used as a platform to carry out animal experiments and cell experiments. It is of great significance for elucidating the mechanism of the biological effects of pulsed electromagnetic fields.

Description

technical field [0001] The invention relates to the research field of electromagnetic biological effects, in particular to an electromagnetic generating device with adjustable frequency band. Background technique [0002] The biological effect of electromagnetic field is an important branch of biomagnetism, and it is also a research hotspot in the fields of biophysics and biomedical engineering. Scholars at home and abroad have done a lot of basic and clinical research in the past few decades. Many experiments have shown that electromagnetic fields can prevent and treat osteoporosis, promote fracture healing, and have obvious biological effects on the nervous system, microcirculatory system, and cardiovascular system of organisms. The biological effects of electromagnetic fields are affected by many parameters such as electromagnetic field parameters, exposure time, and exposure sites. In particular, the biological effects of electromagnetic fields have an obvious "frequenc...
