DEVICE FOR MEASURING INTRAOCULAR PRESSURE Russian patent published in 2018 - IPC A61B3/16 

FIELD: medicine.

SUBSTANCE: device relates to medical technology, namely, a device for measuring intraocular pressure (IOP) through the eyelid. Device contains a movable sleeve installed in the housing to create a constant predetermined load with guides, a support with protrusions; rod with a metal limiter of its movement and a flat base; electromagnetic measuring coil; module of control of verticality of the device when measuring; vertical control indicator and battery. Stem is made with the possibility of elastic deformation of the eye through the eyelid. Electromagnetic measuring coil is connected to the control unit, processing and storage of IOP measurement results. Control unit, processing and storage of results is placed on a vertically installed printed circuit board and configured to convert the linear movement of the rod into an electrical signal proportional to the value of the IOP. Communication module with a transmitter is located on a printed circuit board with a control unit, processing and storage of IOP measurement results. Control unit for processing and storing the results of measuring IOP contains a series-connected high-frequency generator, in the loop of which a measuring electromagnetic coil, a frequency-code converter and a microcontroller are included. Second entrance is made in the form of the "WORK" button, and its third input, its second, third and fourth outputs are made with the possibility of connection with the output of the module for controlling the stem verticality during measurement and the inputs of the display, the Bluetooth module with the transmitter, and the indicator for controlling the verticality of the stem. Support is fixed in the lower part of the sleeve and is made with two wedge-shaped protrusions with rounded support ends equidistant 5–10 mm from the axis of movement of the rod, the protective cover and the housing are made with the possibility of their vertical reciprocating movement relative to the sleeve within specified limits.

EFFECT: reduced time to record, storage of IOP results and, consequently, saving time of the doctor and patient, and also increases the accuracy of measurements.
