DEVICE FOR TREATMENT OF SENSORINEURAL HEARING LOSS USING ENDAURAL PHONOELECTROPHORESIS Russian patent published in 2023 - IPC A61N1/30 A61N7/00 

FIELD: medical equipment.

SUBSTANCE: apparatus for the treatment of sensorineural hearing loss by the method of endaural phonoelectrophoresis contains an ultrasonic frequency oscillation generator, a bandpass filter, an ultrasonic frequency voltage amplifier with a discretely adjustable gain, a power amplifier, the first and second current sensors, the first and second current-to-voltage converters, a switching unit, and an amplitude current detector and amplitude voltage detector, microprocessor, analog-to-digital converter, control panel, piezoelectric emitter, transformer, electrode for electrophoresis, incremental encoder, touch display, controlled current source, polarity switch, second current-to-voltage converter. The piezoelectric emitter is housed in a metal casing. The ultrasound sensor is placed in the housing of the piezoelectric emitter and is mechanically connected to the piezoelectric emitter. The device contains an additional ultrasonic frequency voltage amplifier, an additional amplitude voltage detector, an additional analog-to-digital converter, as well as a button for selecting operating modes, a data input button and a service indicator of the piezoelectric emitter. The ultrasonic emitter is hinged on a flexible bracket with the ability to be fixed in a given position on a fixed base.

EFFECT: increase in the effectiveness of treatment of sensorineural hearing loss and a reduction in rehabilitation time is achieved with automatic control of the power of ultrasonic radiation during the treatment procedures of endaural phonoelectrophoresis and precise positioning of the ultrasound emitter in the patient’s ear canal.
