Eye observation lamp used for ophthalmology department

Abstract

The invention relates to the technical field of eye observation illumination, and discloses an eye observation lamp used for the ophthalmology department. The eye observation lamp comprises a shell, wherein a hydraulic control mechanism is arranged on the upper position in the shell and comprises a sleeve; a piston rod is movably inserted in the sleeve; on the upper end of the piston rod, a pre-tightening spring is fixedly connected in the sleeve; on the lower end of the piston rod, the sleeve is filled with water liquid; and a guide pipe is fixedly inserted into the lower part in the sleeve. A movable rod is pulled upwards, the movable rod sucks the water liquid in the sleeve into a buffer barrel through the guide pipe, the water liquid drives a guide block to move downwards through the piston rod, the guide block moves downwards along a guide rod, the effective electrical resistance, which flows through the guide block, of a main line is smaller and smaller, so that the current of the main line is larger and larger, and the brightness of a bulb is gradually increased; and therefore, the effects that hydraulic control type equal-pipe gradual change adjustment of a high-end equipment technology is adopted, stimulation of the eyes of a patient due to sudden light change is avoided, and use safety is guaranteed are realized.

Description

technical field [0001] The invention relates to the technical field of eye observation lighting, in particular to an ophthalmic eye observation lamp. Background technique [0002] With the continuous development of ophthalmic medical technology, more and more ophthalmic treatment equipment manufactured by high-end equipment manufacturing technology is put into hospitals for medical staff to use. When medical staff observe the eyes of patients with ophthalmic diseases, they usually use With the aid of the eye observation light and computer analysis, doctors can quickly and accurately diagnose the cause of the patient's eye. [0003] When the existing eye observation lamp is observing the patient, when the doctor needs to adjust the brightness of the observation lamp, the brightness of the lamp usually changes suddenly. Huge stimulation will easily lead to the risk of exacerbation of the patient's eye diseases, and there are certain safety hazards. In addition, the existing e...

Problems solved by technology

[0005] Aiming at the deficiencies of the existing technology, the present invention provides an ophthalmic eye observation lamp, which is equipped with a liquid-controlled lamp tube gradient adjustment using high-end equipment technology, avoids sudden changes in light that cause irritation to the patient's eyes, is safe to use, and adopts flexible Rod-shaped connection, more convenient light position adjustment, stable lighting, etc., solves the problem that the general observation light cannot be adjusted by the liquid-controlled light tube with high-end equipment technology, and the light mutation is prone to cause irritation to the patient's eyes. There are potential safety hazards, the inability to use movable rod-shaped connections, the adjustment of the light position is prone to shaking, and the lighting is unstable.
