STATIONARY DEVICE FOR IMPACT OF LOW-FREQUENCY MAGNETIC FIELD ON MEDICAL AND BIOLOGICAL OBJECTS, CONTROL AND PULSE FORMATION SYSTEM, MAGNETIC FIELD INDUCTOR AND MECHANICAL DRIVE SYSTEM OF STATIONARY DEVICE Russian patent published in 2018 - IPC A61N2/00 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medical technology and is intended for multifunctional use in physiotherapy and oncology. Stationary device for the impact of a pulsed low-frequency magnetic field contains a base and a traverse on which the inductors are located. Each inductor has a coolers with an autonomous cooler section. System for control and pulse formation of a given shape contains a simple diode three-phase rectifier, or Larionov type filter to which the bridge circuit is connected on the key power switching transistors with the possibility of connection with the coils of inductors, a current meter with an amplifier, a microcontroller control unit with an A/D converter connected to the bridge circuit through the PWM (pulse width modulation) unit, and a cooling radiator is installed on which the bridge circuit and the rectifier are located. Inductor has a frame with a winding, the sections of which are equal in number of turns and are separated by open ring inserts. Coolers are located on the frame disks. Impact zone is set by means of a mechanical drive system.

EFFECT: group of inventions makes it possible to regulate in a wide range the parameters of the magnetic field and the working zone in an acceptable thermal regime.
