FIELD: medicine. ^ SUBSTANCE: invention concerns medical equipment, particularly devices for ultrasonic treatment. Assembly includes piezo electric converter generating therapeutic ultrasound, base for converter mounting, power amplifier module controlling piezo electric converter. Power amplifier module and piezo electric converter are mounted in the case of therapeutic converter. Channel for cooling fluid is formed between emitting surface of power amplifier module and piezo electric converter. Power amplifier module is mounted at the piezo electric converter side opposite to emitting surface, and emitting surface of power amplifier module is connected to the case of therapeutic converter assembly used as emitting surface of power amplifier module. ^ EFFECT: reduced volume and weight of ultrasonic treatment equipment, significantly damper electromagnetic interference and emission to environment, constant operational parametres of ultrasonic treatment equipment in mass production. ^ 7 cl, 5 dwg |
