Abstract

The invention relates to medicine and veterinary. The device for magnetotherapy comprises a variable generator (1) of current pulses, an energy accumulator (2) and a circuit (3) for discharge of the energy accumulator (2), including a controlled switching element (5) and an inductor (4) capable of producing a therapeutic pulsed magnetic field, and also a unit (7) for controlling the duration of pulses of the magnetic field produced by the inductor (4) and a controller (10) of the amplitude of pulses of the magnetic field. According to the invention, the discharge circuit (3) of the energy accumulator (2) includes a unit (6) for controlling the slope of the leading edge of pulses of the magnetic field produced by the inductor (4). The device is predominantly intended for arresting and relieving acute pain syndromes, phantom limb pain and attacks of bronchial asthma, and also for treating mastities of cattle.
