Description

Предлагаетс  прибор дл  массовых профилактических измерений внутреннего глазного давлени , с целью раннего обнаружени  глаукомы .A device is proposed for mass prophylactic measurements of internal ocular pressure, for the purpose of early detection of glaucoma.

Отличительной особенностью тонометра-индикатора  вл етс  то, что он снабжен спиральной пружиной, оказывающей на глаз посто нное давление при практически любом положении исследуемого субъекта.A distinctive feature of the tonometer-indicator is that it is equipped with a coil spring that exerts a constant pressure on the eye at virtually any position of the studied subject.

На чертеже показан прибор в двух проекци х.The drawing shows the device in two projections.

На корпусе 1 на подшипниках установлена ось 2 и укреплена ручка 5. На оси одним концом закреплена спиральна  пружина 4. Другой конец пружины соединен с проградуированным диском 5, с помощью которого заводитс  пружина. Ось имеет тонкий изогнутый стержень, на свободном конце которого насажена вилка, несуща  прозрачную трехгранную призму 6. Дл  уравновешивани  стержн  и призмы на оси укреплен противовес 7. На основание призмы наноситс  окружность.An axle 2 is mounted on the housing 1 on bearings, and a knob 5 is fastened to the axis. A spiral spring 4 is fixed to the axis with one end. The other end of the spring is connected to a graduated disk 5, with which the spring is winded up. The axis has a thin curved rod, on the free end of which a fork is mounted, carrying a transparent trihedral prism 6. A counterweight 7 is attached to the balance of the rod and the prism on the axis. A circle is applied to the base of the prism.

При установке призмы на глаз и легком надавливании на ручку спиральна  пружина создает посто нное давление, что дает возможность по соответствию кружка, полученного на роговице, и кружка на призме судить о том, нормально ли в данном глазу внутриглазное давление.When the prism is installed on the eye and light pressure is applied to the knob, the spiral spring creates a constant pressure, which makes it possible to judge whether the intraocular pressure in the eye is normal in accordance with the circle obtained on the cornea and the circle on the prism.

Спиральна  пружина тонометра-индикатора позвол ет измер ть внутриглазное давление в короткий срок.The coil spring of the tonometer-indicator allows the intraocular pressure to be measured in a short time.

Предмет изобретени Subject invention

Тонометр-индикатор, снабженный измерительной призмой с нанесенной на нее окружностью, отличающийс  тем, что, с целью массовых определений уровн  внутриглазного давлени , он снабжен спиральной пружиной, оказывающей на глаз посто нное давление при практически любом положении больного.A tonometer indicator, equipped with a measuring prism with a circle applied to it, is characterized in that, for the purpose of mass determination of the level of intraocular pressure, it is equipped with a coil spring that exerts a constant pressure on the eye at virtually any position of the patient.
