FIELD: medicine; magnetotherapy. ^ SUBSTANCE: device can be used in cosmetology, dermatology and for combined influence onto human body in prophylactic and treatment purposes. Device has power amplifier connected with inductor, power supply unit, microcontroller made for generation of frequency sequence of 100 Hz and lower. Device also has switch for supplying supply voltage and for switching the supply voltage off, mode switch connected to control inputs of microcontroller, driver, power breakdown protection circuit and indication units made in form light-emitting diodes switched between signal outputs of microcontroller and null bus. Power amplifier is made on the base of field-effect transistor. Gate of the transistor is connected with output of microcontroller through driver; drain of the microcontroller is connected with null power and source - with output of winding of inductor's coil. Other output of inductor is connected with power bus, Diode is switched in parallel to winding at direction being opposite to supply bus. Device is portable and easy at exploitation. ^ EFFECT: improved medicinal effect. ^ 4 cl, 3 dwg |
