FIELD: medical equipment and can be used in photoreflexotherapy at action of optical radiation on reflexogenic zones, acupuncture points and biologically active points. SUBSTANCE: the device has power source 1, switch 2 (normally-open button) intended for switching on the device and select its functions, voltage regulator 3. The output of voltage regulator 3 is connected directly to the complementing input of first counter 4 and, via inverter 5, to the rest input of second counter 6. The output of pulse generator 7 is connected to the complementing input of counter 6, having seven outputs. The outputs of counter 6, except for the seventh one, are connected to the data input of multiplexer 8, whose control inputs are connected to the outputs of first counter 4. The complementing input of counter 6 is connected to the seventh data input of multiplexer 8, and the complementing input of counter 4 is connected to the eight input. The seventh output of counter 6, via a differentiating network made up of series- connected capacitor 9 and parallel-connected resistor 10, is connected to the input of Schmitt trigger 11, whose output via controlled generator 12 is connected to audio- frequency converter 13. The output of multiplexer 8 is connected to first emitter follower 14, whose emitter circuit incorporates emitter 15 made as a semiconductor light-emitting diode. Replacement and connection of the light-emitting diode with a preset emission wavelength are accomplished via connector 16. For indicating the operation of emitter 15 use is made of first indicating light- emitting diode 17. Provision is made for a power second variant of circuitry. EFFECT: universal small- sized device for photoreflexotherapy provides for treatment of patients with the aid of light and color action at discrete wavelengths, for example, by the Su Jock technique; it is simple in use and controlled only by one button. 2 dwg |
