Description

Предлагаетс  устройство дл  измерени  внутриглазного давлени .A device for measuring intraocular pressure is provided.

Известные устройства дл  измерени  внутриглазного давлени  либо не обладают высокой точностью, либо мало удобны в обращении.The known devices for measuring intraocular pressure either do not have high accuracy or are not very easy to handle.

В предложенном устройстве отличительной особенностью  вл етс  то, что оно позвол ет уменьшить силу давлени  на глаз и сводить к минимуму побочнь е воздействи  на величину внутриглазного давлени  при измерени х. С этой целью устройство выполнено в виде вибрирующего датчика, колебани  которого передаютс  на чувствительный элемент и далее через усилитель - к измерительному или регистрирующему прибору.In the proposed device, a distinctive feature is that it allows to reduce the force of pressure on the eye and to minimize the side effects on the value of the intraocular pressure during measurements. For this purpose, the device is made in the form of a vibrating sensor, the oscillations of which are transmitted to the sensitive element and then through the amplifier to the measuring or recording device.

На чертеже показана блок-схема устройства. К роговице исследуемого глаза / подводитс  вибрирующий датчик 2, оказывающий на глаз в исходном положении небольщое посто нное давление (около 3-5 г). Вибрирующий датчик совершает колебательные движени  с частотой 50 колебаний в секунду и амплитудой около 0,1 мм. Величина амплитуды зависит от величины внутриглазного давлени . Вибрирующий датчик соединен с чувствительным элементом 3 (индуктивный, емкостный или какой-либо другой), который передает через усилитель 4 электрические импульсы на измерительный или регистрирующий прибор 5.The drawing shows a block diagram of the device. A vibrating sensor 2 is applied to the cornea of the examined eye, which exerts a slight constant pressure (about 3-5 g) on the eye in the initial position. The vibrating sensor oscillates at a frequency of 50 oscillations per second and an amplitude of about 0.1 mm. The magnitude of the amplitude depends on the magnitude of the intraocular pressure. Vibrating sensor is connected to the sensing element 3 (inductive, capacitive, or any other), which transmits through the amplifier 4 electrical pulses to the measuring or recording device 5.

Предмет изобретени Subject invention

Устройство дл  измерени  внутриглазного давлени , снабженное датчиком, соприкасающимс  с глазом, отличающеес  тем, что, с целью уменьщени  силы давлени  на глаз и сведени  к минимуму побочных воздействий на величину внутриглазного давлени  при измерени х , оно выполнено в виде вибрирующего датчика, колебани  которого передаютс  на чувствительный элемент, соединенный с усилителем, подающим импульсы на измерительный или регистрирующий прибор, по показани м которых суд т о величине внутриглазного давлени .An apparatus for measuring intraocular pressure, provided with a sensor in contact with the eye, characterized in that in order to reduce the pressure force on the eye and to minimize the side effects on the value of intraocular pressure during measurements, it is made in the form of a vibrating sensor, the oscillations of which are transmitted to a sensing element connected to an amplifier that delivers pulses to a measuring or recording instrument, judging by the indications of which the value of the intraocular pressure is judged.
