Description

Усилие, прикладываемое плунжером 2 к роговице глаза, определ ет величину углублени  плунжера 2 в роговицу. Величина углублени  определ етс  по величине индуцируемого напр жени , снимаемого с гальваномагнитного генератора 6, линейный участок рабочей характеристики которого подбираетс  регул тором 15. По перемещению плунжера и усилию, прикладываемому на роговицу, по таблицам Шиотца определ етс  внутриглазное давление.The force applied by the plunger 2 to the cornea of the eye determines the amount of depression of the plunger 2 into the cornea. The magnitude of the recess is determined by the magnitude of the induced voltage taken from the galvanomagnetic generator 6, the linear portion of the working characteristic of which is selected by the controller 15. The intraocular pressure is determined by the displacement of the plunger and the force applied to the cornea.

Предмет изобретени Subject invention

Датчик внутриглазного давлени , содержащий корпус, плунжер, отличающийс  тем, что, с целью повыщени  точности регистрации давлени , он имеет обойму с двум  цилиндрическими направл ющими, гальваномагнитный генератор, подложку, посто нные магниты, подвижную рамку, регул тор, при этом гальваномагнитный генератор расположен на подложке, а посто нные магниты закреплены на опорах подвижной рамки.An intraocular pressure sensor, comprising a housing, a plunger, characterized in that, in order to increase the pressure recording accuracy, it has a clip with two cylindrical guides, a galvanomagnetic generator, a substrate, permanent magnets, a movable frame, a regulator, and a galvanomagnetic generator is located on the substrate, and the permanent magnets are fixed on the supports of the moving frame.
