Description
Technical Field
The utility model relates to the technical field of test equipment, in particular to a pupil light reflection tester.
Background
When the human eye is stimulated by light, the pupil constricts, known as pupil light reflex. The time that the diameter of the pupil changes from maximum to minimum under the stimulation of external light is called the pupil light reflex time. When a person is in a tired state, the pupil has a longer time to reflect light than when the person is in a mental state.
Pupil light reflex test, which is divided into direct light reflex and indirect light reflex. Direct light reflection, typically illuminating the pupil directly with a flashlight and observing its dynamic response. In normal people, when eyes are stimulated by light, pupils are contracted immediately, and after the light source is removed, the pupils are restored rapidly. Indirect light reflection refers to the immediate contraction of the pupil of the other eye when light is irradiated at one eye, and the pupil of the other eye is dilated by removing the light. When indirect light reflection is detected, one hand should be used for blocking light so as not to irradiate the detection eye and form direct light reflection.
At present, medical staff in clinical practice judge the size of the pupil by himself according to experience. However, this method is highly subjective, and for this problem, patents CN214856572U, CN213551688U, CN212118119U, and the like all disclose measurement auxiliary structures for pupil light reflection test, but these patents cannot perform synchronous test of direct light reflection and indirect light reflection by irradiation of a single light source.
