DEVICE FOR PHYSIOTHERAPY Russian patent published in 1997 - IPC

FIELD: medical technology, particularly, facilities for treatment with different effective agents, using special transducers exited by high voltage at high frequency. SUBSTANCE: device has power supply, generator of high-frequency sinusoidal voltage with high-voltage output, and kit of changeable electric gas-discharge elements used for direct acting on affected region with corona discharge; generator is made in form of self-exited one having powerful transistor keys connected to control circuit involving circuits of output voltage stabilization and adjustment, parametric stabilization and start-up of generator under steady-state conditions, shaping control current signal and protection from inverse current; moreover, input of control circuit is connected to circuit of main-line voltage rectifying and filtration, outputs of control circuit are connected to high-voltage transformer, primary winding of which is coupled with circuit ensuring matching between powerful keys and load, as well as power adjustment; second output of transformer primary winding is coupled with input of key control circuit, and one of matching circuit inputs is connected to circuit of rectifying and filtration; device is supplied with system using electric gas-discharge element for generation of additional effective agent in form of low-frequency mechanical vibrations, remote-exited in gap between body surface and that of electric gas-discharge element due to electrostriction effect, as well as with auxiliary mouthpieces connected to secondary winding of high-voltage transformer and used for aeroionotherapy, ultrasonic therapy, and ozonotherapy. EFFECT: enlarged functional capabilities. 6 cl, 5 dwg
