<p>The inventive device for phototherapy comprises a radiator block (1) provided with at least one radiation source (2), a body of a handle (3), a power supply (4) and a circuit (5) for controlling the supply of the radiator block. Said circuit comprises a microprocessor (6), a controlled, regulated current source (7), and a control panel (8) connected to the microprocessor (6). Said controlled and regulated current source (7) is disposed in the body of a handle (3). The controlled and regulated current source (7) comprises a key converter (71), a current sensor (72), a differential amplifier (73) and a digit to analog converter (74). The controlling and regulating inputs of the controlled and regulated power supply are connected to the corresponding outputs of the microprocessor (6). Said invention can be provided with a digital data exchange port (15) for introducing the operating parameters in accordance with the prescriptions of a doctor and in order to save said parameters in a memory module (14). The radiator block (1) can be additionally provided with the memory module(17) thereof for storing calibration data of the radiation source (2).</p> |
