摘要：
ESSAYthe application for a utility modelLaser measuring Intraocular PressureThe invention relates to medical engineering and can be used in ophthalmology for noncontact measurement of intraocular pressure (IOP). The technical result is to increase the accuracy of the noncontact measurement of intraocular pressure. Said technical result is achieved in that the measuring intraocular pressure comprises a source of radiation directed at the eye, a photodetector, whose output is connected to the recording apparatus, a diaphragm provided with a drive and arranged between the eye and the light detector, a pneumatic system comprising an air tube, the output of which is directed to the eye the same point as the radiation source, according to the decision as a radiation source is a laser, a photodetector integrated in the laser recording device comprises preamplifier having an input coupled to the output of the photodetector and the analog-to-digital converter having an input coupled to the amplifier, the pneumatic system includes a micropump whose output is provided with a pressure sensor, a receiver having an input connected to the output of the micropump, an electromagnetic valve disposed between the output of the receiver and the input air tube meter further comprises an electronic control unit equipped with a serial interface, bidirectional communication with a personal computer, while Rin ode electronic control unit connected to the pressure sensor and the output of analog-to-digital converter, and the electronic control unit outputs are connected to the actuator diaphragm micropump and the solenoid valve.Измеритель внутриглазного давления, содержащий источник излучения для направления на глаз, фотодетектор, выход которого соединен с регистрирующим устройством, диафрагму, снабженную приводом и предназначенную для расположения между глазом и фотодетектором, пневматическую систему, включающую воздушную трубку, выход которой предполагается направлять на глаз в ту же точку,
