Description

Technical Field

[0001] This utility model relates to the technical field of pupil measuring devices, specifically a pupil measuring instrument for forensic identification. Background Technology

[0002] The pupil is the opening in the center of the iris, the gateway for light to enter the human eye. The pupil can dilate and constrict to control the amount of light entering. The pupillary sphincter muscle in the iris controls pupil constriction, while the pupillary dilator muscle controls pupil dilation. Pupil dilation and constriction are not only affected by external light and darkness but also closely related to other factors in the human body. In forensic examinations, a pupillometer is frequently used to measure the pupils of injured persons to determine the cause and time of the accident.

[0003] At forensic examination sites, the person is often already deceased. When using a measuring instrument to measure their pupils, since the eyes of the person involved in the accident are closed, it is very inconvenient to use the measuring instrument. One hand needs to hold open the eyelids to measure the pupils, which is difficult for a single person to do and greatly affects the accuracy of the measurement. Summary of the Invention

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a pupil measuring instrument for forensic identification, including a pupil measuring instrument 1, and a support component 2 is provided on the pupil measuring instrument 1.

[0022] The support assembly 2 includes two threaded posts 201, which are respectively installed on the two side walls of the pupil measuring instrument 1. The first ring 202 and the support part 4 are movably sleeved on the threaded posts 201. The moving part 3 is installed on one side of the support part 4. The pupil measuring instrument 1 includes a connecting end 101. A display screen 102 is provided on the side wall of the connecting end 101. A hand lever 103 is installed on the bottom surface of the connecting end 101. The moving part 3 is provided on one side of the connecting end 101.

[0023] The movable part 3 includes a mounting frame 301, which is installed on the side wall of the connecting end 101 by screws. A mounting block 302 is slidably fitted inside the mounting frame 301. A connecting plate 303 is installed at one end of the mounting block 302. One end of the connecting plate 303 is set on the support part 4. A pull ring 304 is installed at the other end of the connecting plate 303. The forensic doctor can move the connecting plate 303 by pulling the pull ring 304, and adjust the position of the support part 4 with one hand, freeing up the other hand to fix the patient's head or operate other equipment, thus improving work efficiency. A support rod 203 is set on the outer wall of the first ring 202. A first support plate 204 is set at one end of the support rod 203. A slide rail 206 is installed on the top surface of the first support plate 204. One end of the support part 4 is slidably fitted inside the slide rail 206.

[0024] The support part 4 includes a second ring 401, which is movably sleeved on the threaded post 201. The first ring 202 and the second ring 401 are sleeved on the threaded post 201, forming a triangular support structure with the support rod 203 to enhance the overall rigidity and prevent deformation or shaking during use. The support part 4 is separated from the measuring instrument body through the threaded post 201, which facilitates cleaning and disinfection.

[0025] The threaded post 201 is threaded to a threaded ring 205 at its end. The threaded ring 205 fits against the side wall of the second ring 401. The moving part 3 is located on the side wall of the second ring 401. A telescopic plate 402 is provided on the outer wall of the second ring 401. A second support plate 403 is installed at the bottom of the telescopic plate 402. A slider 404 is provided on the top surface of the second support plate 403. The slider 404 slides with the slide rail 206. The sliding fit allows for flexible adjustment of the support spacing to adapt to different eye sizes and avoids affecting the measurement effect due to excessively tight or loose clamping.

[0026] Both the second support plate 403 and the bottom surface of the first support plate 204 are provided with anti-slip strips 5. The anti-slip strips 5 can prevent the measuring instrument from sliding and ensure measurement stability. The first support plate 204 and the second support plate 403 have the same shape. Both the first support plate 204 and the second support plate 403 are curved plates. The design of the first support plate 204 and the second support plate 403 can adapt to the eye socket contours of different users, ensuring that the support plate fits the face stably and improving measurement accuracy.

[0027] When a forensic pathologist uses a pupil measuring instrument to assess vital signs, assist in diagnosis, and evaluate injuries, the pathologist holds the handle 103 of the pupil measuring instrument 1, places the support component 2 on the pupil measuring instrument 1 against the eye socket, and pulls the ring 304 of the moving part 3. The connecting plate 303 drives the second ring 401 to rotate on the threaded post 201, causing the telescopic plate 402 on the outer wall of the second ring 401 to extend and retract. This allows the second support plate 403 and the first support plate 204 to move relative to each other. The second support plate 403 and the first support plate 204 pull the eyelid at the eye socket, enabling the pupil measuring instrument 1 to measure the pupil state. The measurement results are displayed on the display screen 102 on the side wall of the connecting end 101 for easy observation and recording by the forensic pathologist.
