A universal device for ultrasound therapy contains a power supply connected in series, generator, modulator control unit, a pulse generator, a buffer stage, pre- amplifiers, and output transducer, the first output of the output amplifier is connected to the input power source indicator . The modulation generator is in the form of infrasound generator whose output is connected to an input - buffered amplifying stage which is connected to another input of the modulator, and a pulse generator whose output is connected to the input buffer stage, a control input connected to the input control unit outputs the second and third block are respectively connected to control infrasound generator and alternator. Additionally, the apparatus comprises a comparison blocks, dial normalized parameters, the temperature sensor is connected to the unit of comparison and control . A comparison unit is coupled with setpoint normalized parameters and initial power indicator . |
