Description

This invention relates to a device that generates a biostimulatory signal wave, and then irradiates the affected area of a living organism with the magnetic field generated by that signal wave onto the affected area, thereby stimulating the cells and nerves in the affected area and treating pain in that area. Conventionally, devices that treat pain in a living area by irradiating it with a magnetic field to stimulate cells in the affected area are known, such as the one described in Patent Document 1. This treatment device is portable by housing a high-frequency coil and a low-frequency coil, each in a spiral or loop shape, together with an oscillator circuit and a battery within a casing. This treatment device generates magnetic fields in high-frequency and low-frequency coils using constant-frequency high-frequency and low-frequency signals output from an oscillating circuit. By applying the device's casing to the affected area of the body, the magnetic field is irradiated onto the affected area, stimulating the cells. This stimulation promotes the production of neurotrophic factors within the cells, thereby promoting the repair, growth, differentiation, and proliferation of those cells, and ultimately treating pain in the affected area.
