APPARATUS FOR EXTREMELY-HIGH FREQUENCY THERAPY Russian patent published in 1999 - IPC

FIELD: medical engineering. SUBSTANCE: apparatus has extremely-high frequency radiators, power supply unit and control unit. The latter includes microcomputer, switching device, unit responsible for input of commands of selection of operation time and frequency parameters, as well as operating mode indication unit. Power supply unit is connected to supply inputs of switching device, some leads of which are connected to respective leads of microcomputer and other leads, to similar leads of extremely-high frequency radiators. Upon responsible for input of commands of selection of operation time and frequency parameters and operating mode indication unit are connected to respective buses of microcomputer. Apparatus may include indicator of presence of radiator extremely-high frequency power and connector for connection to personal computer. Radiator has extremely-high frequency generator with waveguide and radiating horm antenna. It is positioned in case with dielectric insert. Case accommodates housing of extremely-high frequency generator with waveguide cavity located in it and turning into radiating antenna horm adjacent to dielectric insert of case. Extremely-high frequency generator contains power supply stabilizer and modulator of sweeping the frequency of radiator electromagnetic oscillations installed inside radiator housing. Stabilizer and modulator are connected to semiconductor radiating element of preset frequency range installed in resonator zone adjacent to waveguide cavity. Semiconductor radiating element may be made as avalanche transit-time diode. Radiator is provided with point radiator which may be shaped as tapered housing with dielectric insert positioned in symmetry with housing axis. Dielectric insert may be made in the form of disc with rod installed in its center which contacts vertex of tapered housing, and disc is positioned on housing base. EFFECT: enlarged functional capabilities. 11 cl, 2 dwg, 1 tbl
