SU36583A1 - Zeiss type slit lamp for eye examination - Google Patents

Description

When examining the eyes, widespread use was made of Zeiss, Voigg, etc. slit lamps, in which only a specific type of device can be used (type volt for the Voigg lamp, nitrolamps for most other devices).

In the proposed slit lamp, with the ability to use bulbs of various types and sizes, the flat light bulb has a slot in which the plate with a retractable cartridge can move, for an electric light bulb to be installed at the required distance from dioptric lenses and slits . In addition, to roughly determine the color sensation, the wall opposite to the optical tube tube of the illuminated box is provided with a hole and a strand with slots for colored glass located opposite the hole for the diopter tube.

In the schematic drawing of FIG. 1 is a side view of the proposed lamp, and FIG. 2-vertical section of the diopter tube .- and,

The lighting box of the proposed lamp is a circular me- (88) V,,; -,: -; - a metal cylinder 1, fitted on the sides with one or more opposite holes of the same diameter, one for a tube 2 with a lens (4-20 L) installed at the opening itself, and the other for colored glasses mounted in the grooves attached to the outside of the frame 3

The cylinder 1 is closed with a lid fitted with a slit for placing the plate 4, which is moved in it in the horizontal plane, carrying the cartridge S for the electric lamp. The cartridge 5 can also move in a horizontal plane, but in a direction perpendicular to the movement of the plate 4. The tube 6 is tightly inserted into the tube 6 with a lens (+20 L) and with a slit diaphragm 7. The cylinder 1 is mounted on a retractable stand 8, moving along the base 9, on which G1RAY is also mounted a stand 10 for the illumination lens 11 (- | -13D ) moved along the graduated ruler. And a tripod 12 for the head holder 13.

Due to the movement of the cartridge 5 in two mutually perpendicular directions in the horizontal plane, it is possible to use electric lamps of various types and installation f

HQBKH THEM at the required distance from dioptric lenses.

The subject matter of the invention

1. 1 Ceissa type Zeiss lamina for eye research, characterized in that the cylindrical box accommodating the illumination source is provided in one of the flat beds with a slit for placing the light bulb holder moving in two mutually perpendicular in the horizontal plane, with The goal is to make it possible to use bulbs of different types and sizes and install them at the required distance from the box, away from the side walls of the box, dioptric lenses and the slit. , 2. In the lamp p6 p. 1, use for a rough determination of the color sensation of colored glass placed in a grooved frame located at the aperture of the side wall of the cylindrical box diametrically opposite to the place of discharge of the dioptric tube.
