Изобретение относитс  к медицинс- КИМ приборам, примен емым в офтальмологии , а именно, дл  изучени  гемодинамики глаза.The invention relates to medical IM devices used in ophthalmology, namely, to study the hemodynamics of the eye.

Цель изобретени  - повышение точности измерени  импеданса тканей глаза путем уменьшени  усили  компрессии .The purpose of the invention is to improve the accuracy of measuring the impedance of eye tissues by reducing the compression gain.

На чертеже изображен предлагаемый датчик.The drawing shows the proposed sensor.

Офтальмореографический датчик состоит из корпуса с внешней стенкой 1 с патрубком 2, внутренней стенки 3j выполненной в виде контактной линзы, имекндей по всей площади перфорационные отверсти  4 и электроды 5, распот ложенные со стороны, обращенной к глазу. Станки герметично соединены Одна с другой по всей периферии (в ijiecTe 6). Выводы от электродов 5 гер- 1| етизированно выведены и присоединены к внешним проводам 7.The ophthalmoreographic sensor consists of a housing with an external wall 1 with a nozzle 2, an internal wall 3j made in the form of a contact lens, and there are perforations 4 in the entire area and electrodes 5 located on the side facing the eye. Machines are tightly connected to one another along the entire periphery (in ijiecTe 6). Conclusions from electrodes 5 ger- 1 | Etizirovanno withdrawn and attached to the external wires 7.

Офтальмореографический датчик работает следующим образом.Ophthalmological sensor works as follows.

Датчик накладывают на глаз так, что роговица расположена в центре. С помощью внешнего устройства через патрубок 2 и перфорационные отверсти  4 создаетс  вакуум (например, с помощью присоски).Sensor impose on the eye so that the cornea is located in the center. Using an external device, a vacuum is created through the nozzle 2 and the perforations 4 (for example, using a suction cup).

При этом внутренн   поверхность стенки 3 плотно прилегает к передней части глаза, обеспечива  надежный и равномерный контакт его тканей с электродами 5. Жесткость внутренней стенки 3 исключает деформацию передней части глаза, что исключительно важно дл  проведени  гемодинамичес- ких .исследований. Внешние провода 7 подключают к реографу и производ т запись реограммы. После проведени  исследований снимаетс  вакуум и датчик убирают с глаза,At the same time, the inner surface of the wall 3 fits snugly to the anterior part of the eye, ensuring reliable and even contact of its tissues with electrodes 5. The rigidity of the inner wall 3 prevents deformation of the anterior part of the eye, which is extremely important for conducting hemodynamic studies. The external wires 7 are connected to the rheograph and the recording of the rheogram is made. After research, a vacuum is removed and the sensor is removed from the eye,

Использование датчика позвол ет объективно проводить исследовани  гемодинамики глаза, что способствует точности постановки диагноза.The use of a sensor allows objective examination of the hemodynamics of the eye, which contributes to the accuracy of the diagnosis.
