DEVICE FOR UHF-THERAPY Russian patent published in 1994 - IPC

FIELD: medical engineering. SUBSTANCE: device guarantees dosage of uhf-radiation power and supporting it on given level with high efficiency during carrying out procedures of UHF-therapy owing to use of UHF-generator of key type whose inlet is connected to the patient contour through output circuit and circuit of power regulation used by UHF-generator from power source including pick-up of utilized current whose outlet are connected: the first one to the UHF-generator inlet through executing block, the second one - to comparison element with power pick-up at its first inlet and former of regulating signal whose inlets are connected to the outlet of sawtooth voltage generator and comparison element, and outlet - with the second inlet of executing block. In additional to that stabilization of outlet power of device is carried out by means of used by UHF-generator. Error at receiving of regulating signal doesn't depend on degree of UHF-generator misalignment with load because feedback circuit doesn't elements of HF-highway. EFFECT: exact dosage of UHF-radiation power. 3 dwg
