FIELD: medical equipment; ophthalmology.
SUBSTANCE: pressure indicator consists of optic system, excluding impact of outer interferences, consisting of light diode, elastic element in form of gate, rigidly fixed on one end, microlens on tubular holder on the other end, doubled photodiode, and piezoelectric element, which registers pulsations of vessel walls, which in form of signals are transferred to measurement unit, consisting of power unit, unit of signal amplification and processing, microcontroller, transmitting data to computer for digital signal processing, information presentation, automatic calibration and testing of indicator before each measurement.
EFFECT: increase of accuracy of measurement results and extension of functional possibilities.
