MAGNETIC STIMULATOR Russian patent published in 2009 - IPC A61N2/02 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment and can find application in functional diagnostics of nervous system disturbance. Said device comprises a power unit, a power transistor, a pulse transformer with its secondary winding connected to a power capacitor through an output diode, and a power thyristor with a magnetic inductor. The voltage divider and the power thyristor are connected to the output of the power capacitor. A driver is connected to the driving point of a power transistor. A current sensor connected to the power transistor is connected to the first input of the driver with its output. Besides the device is provided with a pump, a heat exchanger, an expansion container, Peltier elements and a radiator. The inductor is made of a metal tube. The Peltier elements with their cooling surface are placed on the wall of the heat exchanger. The heating surface of the Peltier elements is connected to the radiator, and as a cooling liquid, the liquid with high dielectric properties is chosen.

EFFECT: invention allows minimising thermal exposure of the magnetic inductor heated with magnetic stimulus and thereby improving information value of the examination.
