Embodiment Construction
[0009] In the indirect light reflection eye detector shown in the figure, one end of the telescopic cylinder is fixed on the light source end of the small flashlight, and the other end is buckled on the subject's eye, and the switch of the flashlight is turned on to observe the change of the pupil of the other eye. The circumference of one end buckled on the eyes can be covered with a holster, and when the light is irradiated, the light can only enter the eye, and the other eye is not affected by the light.

The invention provides an HTJ-I type indirect light reflex sight tester which can check eyes more accurately and quickly. When the tester is used, one end of a telescopic light avoiding tube covers the light source end of a small flashlight, while the other end covers an eye of a user; and a leather sleeve can be arranged around the end of the telescopic light avoiding tube covering the eye, so that the light can only enter the eye, and the other eye can not be affected by the light.
Description
Technical field [0001] The patent of the present invention relates to an indirect light reflection eye detector. It can be used by clinicians in various disciplines, including neurosurgery, neurology, pediatrics, internal medicine, ophthalmology, etc. It is especially suitable for checking the indirect pupillary light reflex. Background technique [0002] At present, clinical doctors often block the light with one hand when performing indirect light reflection examination, so as to prevent the light from shining on the eye to be examined and form direct light reflection, but it is inevitable that a small amount of light entering the examination will affect the test results. Contents of the invention [0003] In order to overcome the problem that a small amount of light enters and affects the detection result when indirect light reflection inspection is performed in the existing eye examination. The patent of the present invention provides an indirect light reflection eye ...
