TELEMETRIC ULTRASOUND DEVICE FOR DIAGNOSING SENSORINEURAL HEARING LOSS Russian patent published in 2020 - IPC A61B5/12 A61B8/00 H04R25/00 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. Telemetric ultrasonic device for diagnosing the sensorineural hearing loss comprises an ultrasonic frequency oscillation generator, a band-pass filter, amplifier with discretely controlled gain and power amplifier, current sensor, piezoelectric emitter, current-to-voltage converter, switching unit, a control panel with buttons for increasing and reducing radiation power, changing the rate of controlling power, as well as digital segment indicators, a microprocessor, first and second amplitude detectors and an analogue-to-digital converter. Device is equipped with a button for selecting an ultrasound exposure point on the patient's head and a button for fixing the threshold level of perception of an ultrasonic signal located on the control panel and connected to the microprocessor. Besides, the device comprises a computer connected to a microprocessor and an Internet network, a monitor and a printer connected to a computer. Ultrasonic generator is made in the form of generator controlled by voltage. Control input of the ultrasonic generator is connected to the microprocessor.

EFFECT: higher accuracy of measurement due to automatic tuning of ultrasonic signal generator frequency to resonant frequency of ultrasonic radiator; enabling the automated generation of a patient's examination protocol and use of the device in telemedicine systems.
