A neurology pupillary light reflex diagnostic device and method of use thereof

Abstract

The invention discloses a neurology department pupil light reflex diagnostic device and a use method thereof, and belongs to the field of neurology department diagnostic apparatuses. The neurology department pupil light reflex diagnostic device includes a head placement window and a pupil inspection mechanism, where the radian radiuses of the head placement window and the pupil inspection mechanism are consistent, and are parallel to each other; a stimulation light source is fixed on a head end of a rotation rod; the rotation rod can rotataly move on a semicircular sliding rail; an infrared distance measurement instrument is rotatably hanged on a free end of the rotation rod; a reflective band attaches to a bottom of a supporting sliding seat; a bearing plate is fixed under a fixing plate;the center of a lower surface of the bearing plate is fixed on a piston rod of a hydraulic cylinder; and image acquisition devices are fixed on two sides of an inner surface of the supporting slidingseat. The neurology department pupil light reflex diagnostic device can achieve electric control automation, can greatly reduce the working load of medical workers, can achieve precise pupil inspection, and can ensure the accuracy of the diagnosis result; the stimulation light source is excellent in adjustability and controllability, can monitor conditions of the two pupils at the same time, is reasonable in the optimized structural design, and has positive impact on a pupil light reflex test.

Description

technical field [0001] The invention relates to the field of neurology diagnostic devices, in particular to a neurology pupil light reflection diagnostic device and a method for using the same. Background technique [0002] Eyes are the most important sensory organs for human beings to perceive external information. Among perceptions such as vision, smell, touch, taste, and hearing, the human brain feels the most intuitively and receives the largest amount of information, which accounts for about 70% of the information received by the human body from the outside world. %. In the visual function of the human eye, the pupil has important academic and clinical research value due to its special light sensitivity. The diameter of the pupils of ordinary people can vary from 2mm to 8mm, showing different sizes at different ages, and can also shrink or dilate due to the influence of diseases or drugs. [0003] When the light hits the eye, it causes the pupil to constrict, which is...

Problems solved by technology

It has the following disadvantages: the adjustment of the stimulating light source is poor, which has a great negative impact on the test results; the changes of the pupils can only be roughly observed, and objective, quantitative and accurate measurements cannot be carried out, which greatly reduces the accuracy of the diagnostic results; Limited by manpower, it is difficult for medical staff to observe the changes of the two pupils at the same time, and it is easy to miss an important diagnostic basis; and the controllability of the stimulating light source is poor, which is not conducive to ensuring the consistency of non-research factors in the two tests
