Description
Technical field [0001] The invention belongs to the technical field of magnetic field biology experiments, and relates to a low-frequency electromagnetic field cell processing instrument that can realize multi-parameter control of magnetic induction intensity, magnetic field frequency, and magnetic field type. Background technique [0002] In recent decades, a large number of domestic and foreign studies and clinical experiments have confirmed that magnetic therapy has a good medical effect on certain diseases, such as osteoporosis, fracture healing, soft tissue injury, hyperlipidemia and other diseases or trauma. It is in the medical equipment market. A large number of magnetic therapy devices have also appeared on the Internet. However, due to different manufacturers of existing electromagnetic therapy devices, the frequency and magnetic induction intensity parameters used in the products are often very different, and the parameter setting lacks effective experimental basis. Th...
