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. Example

[0028] Please see Figures 1-4 The present invention provides the following technical solution:

[0029] A pupil measuring pen, comprising:

[0030] Pupil Pen Body 1;

[0031] Measuring sleeve 2 is fitted onto the outside of the pupil pen body 1;

[0032] Pupil light 3, which is located at the lower end of the pupil pen body 1;

[0033] A flat convex mirror 4 is fixedly connected to the inner circumference of the measuring sleeve 2.

[0034] The graduated mirror 5 is fixedly connected to the lower end of the measuring sleeve 2;

[0035] Linear scale 6, which is located inside the scale mirror 5;

[0036] Circular scale 7 is located inside the scale mirror 5.

[0037] In a specific embodiment of this utility model, the pupil pen body 1 serves as the basic structure of the entire device, providing support and housing the battery and other electronic components. The pupil lamp 3 is located at the lower end of the pupil pen body 1, emitting a warm yellow light suitable for observing the pupil. The plano-convex mirror 4 is fixedly connected to the inner circumference of the measuring sleeve 2, its function being to convert the astigmatic light emitted by the pupil lamp 3 into parallel light, ensuring that the area of ​​light illuminating the pupil does not change with distance. The scale mirror 5 is fixedly connected to the lower end of the measuring sleeve 2, containing a linear scale 6 and a circumferential scale 7, used for directly measuring the size of the pupil. When using this invention to measure the pupil, first turn on the pupil lamp 3, which emits... The warm yellow light is converted into parallel light by the plano-convex mirror 4 and then stably illuminates the patient's pupil. At this time, because the light is parallel, the size of the light spot on the pupil remains unchanged regardless of the distance between the pupil and the light source. Then, by observing the linear scale 6 and the circumferential scale 7 inside the scale mirror 5, the diameter and circumference of the pupil can be accurately read, thus achieving accurate measurement of the pupil size. This pupil measuring pen not only improves the accuracy of pupil examination and reduces human error, but is also easy to operate and is very suitable for widespread application in clinical settings. In addition, it is also of great value for studying pupillary reflexes and diagnosing neurological diseases.

[0038] Please refer to the details. Figures 1-4 The distance between the flat convex mirror 4 and the output end of the pupil lamp 3 is two centimeters.

[0039] Example 2 is based on Example 1: When in use, the pupil lamp 3 is turned on, and the light emitted by it is converted into parallel light by the plano-convex mirror 4 set at a distance of 2 cm, and then stably illuminates the patient's pupil to enlarge the illumination diameter of the pupil lamp 3.

[0040] Please refer to the details. Figures 1-4 The diameter of the circle formed by the circular scale 7 is four millimeters, and the maximum scale of the straight scale 6 is 5.5 millimeters.

[0041] In this embodiment: The diameter of a human pupil is generally 2.5 mm to 4 mm. When the pupil diameter exceeds 5 mm, it is considered dilated. The linear scale 6 ensures that even larger pupils can be accurately measured while maintaining sufficient precision. The circumferential scale 7 takes into account the typical size range of the pupil, enabling the tool to accurately measure the circumference of the pupil.

[0042] Please refer to the details. Figures 1-4 The flat convex mirror 4 has a yellow light interlayer inside.

[0043] In this embodiment, the plano convex mirror 4, in addition to its original function of converting astigmatism into parallel light, now has a yellow light interlayer inside. The function of this yellow light interlayer is to filter out unnecessary spectral components and only allow warm yellow light suitable for observing the pupil to pass through, thereby improving the comfort and accuracy of the examination.

[0044] Please refer to the details. Figures 1-4 The pupil pen body 1 has a rotating groove 9 on its circumferential surface, and the measuring sleeve 2 has a rotating sleeve 10 on its inner circumferential wall. The measuring sleeve 2 is rotatably connected to the circumferential surface of the pupil pen body 1 through the rotating sleeve 10.

[0045] Example 3 is based on Example 2: A rotating groove 9 is provided on the circumferential surface of the pupil pen body 1. It is used to cooperate with the rotating sleeve 10 to realize the rotation function of the measuring sleeve 2. The rotating sleeve 10 is set on the inner circumferential wall of the measuring sleeve 2. Through cooperation with the rotating groove 9, the measuring sleeve 2 can rotate freely around the pupil pen body 1, which is convenient for adjusting the best observation angle. The rotation adjustment function helps to find the most suitable observation position, thereby improving the accuracy of measurement.

[0046] Please refer to the details. Figures 1-4 A rotating wheel 8 is provided on the circumferential surface of the measuring sleeve 2.

[0047] Example 4 is based on Example 3: The rotating wheel 8 is located on the circumferential surface of the measuring sleeve 2. The user can control the rotational position of the measuring sleeve 2 relative to the pupil pen body 1 by rotating the wheel. This design simplifies the adjustment process and improves the convenience of operation.

[0048] The working principle and usage process of this utility model: The pupil pen body 1 serves as the basic structure of the entire device, providing support and housing the battery and other electronic components. The pupil lamp 3 is located at the lower end of the pupil pen body 1, emitting a warm yellow light suitable for observing the pupil. The plano-convex mirror 4 is fixedly connected to the inner circumference of the measuring sleeve 2, and its function is to convert the astigmatic light emitted by the pupil lamp 3 into parallel light, ensuring that the area of ​​light illuminating the pupil does not change with distance. The scale mirror 5 is fixedly connected to the lower end of the measuring sleeve 2, containing a linear scale 6 and a circumferential scale 7, used to directly measure the size of the pupil. When using this invention to measure the pupil, first turn on the pupil lamp 3, its light... The warm yellow light emitted is converted into parallel light by the plano-convex mirror 4 and then stably illuminates the patient's pupil. At this time, because the light is parallel, the size of the light spot illuminating the pupil remains unchanged regardless of the distance between the pupil and the light source. Then, by observing the linear scale 6 and the circumferential scale 7 inside the scale mirror 5, the diameter and circumference of the pupil can be accurately read, thus achieving accurate measurement of pupil size. This pupil measuring pen not only improves the accuracy of pupil examination and reduces human error, but is also easy to operate and is very suitable for widespread application in clinical settings.
