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...

[0003] In numerous patent studies (specific low-frequency pulsed electromagnetic apparatus for treating osteoporosis, patent application number: CN200720079911; a low-frequency electromagnetic field osteoporosis treatment bed, patent application number: CN201110423033; low-intensity pulsed magnetic field therapeutic apparatus: CN02224739), the experimenter Various magnetic field generating devices are used, and the magnetic field parameters are only roughly described. The frequency of low-frequency electromagnetic fields (<300Hz) with biological effects in literature reports generally refers to the repetition period of its pulse signal. Many In patents and monographs on the biological effects of pulsed electromagnetic fields, the time-domain repetition period of pulsed electromagnetic fields is generally inconsistent. The frequency window determined by many researchers is mainly based on many random experiments, so it is determined from the perspective of the time-domain repetition period of pulsed electromagnetic field The frequency window of its biological effects is blind and difficult to operate, which leads to inconsistency and low repeatability of many experimental research results
