Device used for rapidly treating damage or degeneration of bone and cartilage by applying C-type electromagnet to generate high magnetic flux density and single pulsed electromagnetic field
A device used for rapidly treating damage or degeneration of bone and cartilage by applying a C-type electromagnet to generate a high magnetic flux density and single pulsed electromagnetic field is disclosed, which comprises a power supply section, an excitation section and a control section. In the operation of the disclosed device, after a large capacitor is electrically stored by a small constant current, a rapid discharge process is executed on the basis of RLC damped oscillation principle, thereby generating a homogeneous magnetic field with an instant large flux density (about 5 millisecond) and an adjustable 0.05~1.5 Tesla (referred as "T" ). The power supply section includes a high voltage transformer, a high voltage rectifier, a PWM (Pulse Width Modulation) driver, a high voltage solid state switch and a large capacitance component. The high voltage transformer and the high voltage rectifier are utilized to generate a DC high voltage, and then the PWM driver and the high voltage solid state switch are utilized to execute a constant current-constant voltage charging control in a PWM approach to charge the large capacitance component and to constitute a large energy storage function, so that purposes of preventing the current ripple on a power input end during charging, reducing power consumption and providing a silicon-controlled rectifier (SCR) that is able to rapidly discharge can be achieved. The excitation section, which includes a C-type electromagnetic iron core, a pair of excitation coils and a treatment carrier, are utilized to produce a high flux density and single pulsed electromagnetic fields to treat the damage or degeneration of limb bones and cartilages of organism (including humans and animals). The control section, which includes a central control unit and an operative panel, are utilized to execute power on, operation control (activation/termination of equipment operation, operation count setting, temperature setting of electromagnetic iron
