Abstract

The invention relates to medical technology and can be applied to the treatment of diseases of the musculoskeletal system by a magnetic field. The purpose of the invention is to reduce the treatment time by obtaining an optimal magnetic field pulse shape. For this purpose, an apparatus for magnetic therapy is used. It works as follows: at the initial time, the thyristor 3 of the current pulse generator 1 is closed and the battery of capacitors 2 is charged from the power source 5. When a current pulse from the control unit 10 is applied to the control electrode of the thyristor 3, the battery of capacitors is discharged and a magnetic capacitor appears in the inductor 4 a field whose pulses are bell-shaped. To adjust the pulse shape of a magnetic field with S, a thyristor 7 is used, which opens with a delay relative to thyristor 3. The delay is controlled by a delay line. 1 il. 4j OP taoA. to yu

(54) DEVICE FOR MAGNETOTHERAPY (57) The invention relates to medical equipment and can be used to treat diseases of the musculoskeletal system with a magnetic field. The purpose of the invention is to reduce the treatment time by obtaining the optimal magnetic field pulse shape. For this, an apparatus for magnetotherapy is used. It works as follows: at the initial moment, the thyristor 3 of the current pulse generator 1 is closed and the capacitor bank 2 is charged from the power source 5. When a current pulse is supplied from the control unit 10 to the control electrode of the thyristor 3, the capacitor battery is discharged and a magnetic field appears in the inductor 4, pulses which have a bell-shaped shape. To adjust the shape of the magnetic field pulses, a thyristor 7 is used, which opens with a delay in relation to the thyristor 3. The delay value is controlled by the delay line. 9. 1 ill.
