Embodiment 1

[0040] Such as Figure 1-3 shown

[0041] A device for diagnosing pupillary light reflex in neurology. The main body is integrally formed and fixed to the eye with a fixing belt. The front end is the eye contact part 3 that contacts the eye and fully closes the eye. The image acquisition part 1 and the stimulating light source part 2 are installed, and both are connected with the control part 4 installed on the stimulating light source part 2;

[0042]The eye contact part 3 includes a base 301. The base 301 is a rectangular parallelepiped with smooth corners, and a through hole 303 corresponding to the eye is opened inside. The periphery of the through hole 303 is covered with a ring of elastic washers, and the outer wall of the front end is covered with a layer of The high-density sponge 302 that fits the outline of the human eye seals the eye area, and the surface is painted black. The rear end of the eye contact part 3 is installed with an integrally formed image acquisiti...

Embodiment 2

[0052] A method for using a device for diagnosing pupillary light reflex in neurology, comprising the following steps:

[0053] Step 1. Wear the pupillary light reflex diagnostic device on the patient's eyes through the fixing belt

[0054] Put the through hole part of the eye contact part on the eye end to cover, and the rear end is fixed by the connecting buckle of the fixing belt. At the same time, adjust the earmuffs to cover the ear, and adjust it to an appropriate tightness to ensure contact with the eye. The part will not leak light;

[0055] Step 2. Pre-correction of pupillary light reflex

[0056] Adjust the photoreflex diagnostic device so that the pupils of both eyes of the subject are located in the center of the display window, so that the stimulus light source and the center of the pupils are in a straight line during the examination;

[0057] Step 3. Detection of pupillary light reflex

[0058] Set the parameters of the infrared camera, stimulus light source ...

Embodiment 3

[0064] The application of a neurology department pupillary light reflex diagnosis device in the neurology department pupillary light reflex diagnosis.

[0065] First get rid of whether the test patient has used medicine in the whole body or the eyes locally in the near future, so that the reflection of the pupil is affected. Before the examination, the patient closed his eyes and had a quiet rest for 5 minutes. When the device is worn, the device is similar to VR, mainly including eye contact parts, image acquisition parts, stimulating light source parts and control parts. For the eyes, automatic pupillary light reflex diagnosis is realized, without manual operation, and control errors in the manual operation process are avoided;

[0066] Then observe through the display screen according to the above operation method, adjust the eye position of the subject so that the pupils of both eyes are respectively located in the display / control module, check the alternate stimulation mo...

Abstract

The invention discloses a pupillary light reflex diagnosis device in the neurology department, and relates to the technical field of medical instruments. The device is integrally formed and fixed to the eye through a fixing belt, wherein the foremost end is an eye contact part in contact with the eye and completely closing the eye, the inner portion is provided with an image acquisition part and astimulating light source part from the front end to the rear end in sequence, and the eye contact part, the image acquisition part and the stimulating light source part are connected with a control part arranged on the stimulating light source part separately. The pupillary light reflex diagnosis device has the advantages that pupillary light reflex can be diagnosed and recorded accurately, the operability and convenience are better, and the device is suitable for popularization and application in medical mechanisms.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for diagnosing pupillary light reflex in neurology and its application. Background technique [0002] Light reflex is a test to check pupillary function, divided into direct light reflex and indirect light reflex. Direct light reflex, usually by shining a flashlight directly on the pupil and observing its dynamic response. In normal people, when the eye is stimulated by light, the pupil shrinks immediately, and the pupil recovers quickly after the light source is removed. Indirect light reflex means that when the light shines on one eye, the pupil of the other eye shrinks immediately, and the pupil dilates when the light is removed. When checking the indirect light reflection, the light should be blocked with one hand to avoid direct light reflection from being irradiated to the inspection eye. Since the center of the pupillary light reflex is in the anterior ...
