The measuring mechanism has a handle fixed to its left outer wall and an opening on its surface. A shell surrounds the measuring mechanism. A movable plate is connected to the right end of the measuring mechanism, and a slide rail is installed inside the movable plate. A moving plate is placed inside the slide rail, and a magnifying glass is positioned above the moving plate. A slot is fixed to the right side of the magnifying glass, and a top cover is provided to the right side of the slot. A storage area is located to the right of the top cover, and a locking block is fixed to the right side of the storage area. The pupil measuring device is located above the locking block.

[0004] Existing ophthalmic care assessment rulers, such as the one mentioned above, are designed to fit the face and accurately measure eye width and distance. However, in practice, since the ruler does not have marking components, medical staff need to keep the ruler in contact with the patient's condition while recording the eye width and distance data, which is inconvenient. Therefore, there is an urgent need to propose a corresponding ophthalmic care assessment ruler to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an ophthalmic care assessment ruler in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An ophthalmic care assessment ruler includes a ruler body and a grip base. The outer wall of the ruler body is integrally formed with a scale strip. A measuring component for measuring the pupil size of a patient is integrated between the grip base and the ruler body. The outer wall of the scale strip is fixedly connected with a first, second, third, and fourth label sleeve, and the first, second, third, and fourth label sleeves are all transparent.

[0008] Preferably, the measuring component includes a limiting part for horizontally limiting the inner lining strip, the open end of the inner lining strip is fixedly connected to the outer wall of the grip, the outer wall of the inner lining strip is slidably connected to the inner wall of the ruler through a sliding groove, and multiple sets of measuring perforations are integrated inside the inner lining strip.

[0009] Preferably, the limiting part includes a slide block fixedly connected to the top of the inner lining strip, and the outer wall of the slide block is slidably connected to the inner wall of the ruler through a transverse groove.

[0010] Preferably, a magnetic block is embedded in the inner wall of the slide block, and two sets of metal plates are fixedly connected to the inner wall of the ruler, with the two sets of metal plates being horizontally symmetrically distributed.

[0011] Preferably, damping pads are fixedly connected to the inner walls of the first, second, third and fourth standard sleeves, and the outer walls of the multiple sets of damping pads abut against the outer walls of the scale strip.

[0012] Preferably, the outer wall of the grip is provided with a rough texture, and the grip and the inner lining strip are fixedly connected by screws.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the ruler is placed in front of the patient's face. The first and second labels are moved so that the two sets of labels are aligned with the two ends of one of the patient's eyes. Similarly, the third and fourth labels are moved so that the two sets of labels are aligned with the two ends of the other eye. Then the ruler is removed directly. At this time, the distance between the first and second labels and the third and fourth labels is the pupil width of the patient's two eyes, while the distance between the second and third labels is the pupillary distance of the two eyes. This eliminates the need to maintain the ruler in contact with the patient's face for a long time, and the level view allows for clearer observation of the scale data, thereby improving the convenience of using the ophthalmic nursing assessment ruler.

[0015] 2. In this application, during the measurement of pupil width and pupillary distance, the magnetic block inside the slide is attracted to one of the metal plates, and the inner liner is completely integrated into the ruler body. After the pupil width and pupillary distance are measured, the inner liner is pulled by the grip, and the slide slides along the transverse groove until the magnetic block is attracted to another set of metal plates, thereby fixing the inner liner again. At this time, the inner liner extends out of the ruler body, and the patient's pupil can be measured through the measuring perforation. This ensures the functionality of the evaluation ruler while reducing the overall volume of the ruler body through the telescoping mechanism. Attached Figure Description

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] An ophthalmic care assessment ruler includes a ruler body 1 and a grip base 7. The outer wall of the ruler body 1 is integrally formed with a scale strip 2. A measuring component for measuring the pupil size of a patient is integrated between the grip base 7 and the ruler body 1. The outer wall of the scale strip 2 is fixedly connected with a first sleeve 3, a second sleeve 4, a third sleeve 5, and a fourth sleeve 6, and the first sleeve 3, the second sleeve 4, the third sleeve 5, and the fourth sleeve 6 are all transparent.

[0025] Place ruler 1 in front of the patient's face. Move label 3 and label 4 so that the two sets of labels are aligned with the two ends of one of the patient's eyes. Similarly, move label 5 and label 6 so that the two sets of labels are aligned with the two ends of the other eye. Then remove ruler 1 directly. At this time, the distance between label 3 and label 4 and label 5 and label 6 is the pupil width of the patient's two eyes, while the distance between label 4 and label 5 is the pupillary distance of the two eyes. In this way, the ruler 1 does not need to be kept in contact with the patient's face for a long time, and the scale data can be observed more clearly when looking straight ahead, thus improving the convenience of using the ophthalmic nursing assessment ruler.

[0026] Specifically, such as Figure 2 and Figure 4As shown, the measuring assembly includes an inner liner 8 and a limiting part for horizontally limiting the inner liner 8. The open end of the inner liner 8 is fixedly connected to the outer wall of the grip 7. The outer wall of the inner liner 8 is slidably connected to the inner wall of the ruler 1 via a sliding groove. Multiple sets of measuring through holes 10 are integrated inside the inner liner 8. The limiting part includes a slide block 11 fixedly connected to the top of the inner liner 8. The outer wall of the slide block 11 is slidably connected to the inner wall of the ruler 1 via a transverse groove 12. A magnetic block 13 is embedded in the inner wall of the slide block 11. Two sets of metal plates 14 are fixedly connected to the inner wall of the ruler 1. The two sets of metal plates 14 are horizontally symmetrically distributed. During pupillary distance measurement, the magnetic block 13 inside the slide 11 is attracted to one of the metal plates 14, and the inner liner 8 is completely attached to the inside of the ruler body 1. After completing the pupillary width and pupillary distance measurement, the inner liner 8 is pulled by the grip 7, and the slide 11 slides along the transverse groove 12 until the magnetic block 13 is attracted to another set of metal plates 14, thereby fixing the inner liner 8 again. At this time, the inner liner 8 extends out of the ruler body 1, and the patient's pupil can be measured through the measuring perforation 10. This ensures the functionality of the assessment ruler while reducing the overall volume of the assessment ruler through the telescopic method.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, damping pads 9 are fixedly connected to the inner walls of standard sleeve 3, standard sleeve 4, standard sleeve 5, and standard sleeve 6. The outer walls of multiple sets of damping pads 9 abut against the outer walls of the scale strip 2, thereby providing damping characteristics for standard sleeve 3, standard sleeve 4, standard sleeve 5, and standard sleeve 6, ensuring the stability of the position of standard sleeve 3, standard sleeve 4, standard sleeve 5, and standard sleeve 6. The outer wall of the grip 7 is provided with a rough texture, and the grip 7 and the inner lining strip 8 are fixedly connected by screws, ensuring the stability of the grip 7 and the ease of disassembly and assembly of the grip 7 and the inner lining strip 8.

[0028] Working principle: Place ruler 1 in front of the patient's face. Move label 3 and label 4 so that each set of labels aligns with the ends of one of the patient's eyes. Similarly, move label 5 and label 6 so that each set of labels aligns with the ends of the other eye. Then, remove ruler 1. At this point, the distance between label 3 and label 4, and between label 5 and label 6, represents the pupillary width of both eyes, while the distance between label 4 and label 5 represents the pupillary distance. This eliminates the need to maintain ruler 1 in contact with the patient's face for an extended period, and the level gaze allows for clearer observation of the scale data, thus improving... To improve the ease of use of the ophthalmic nursing assessment ruler, during the measurement of pupil width and pupillary distance, the magnetic block 13 inside the slide 11 is attracted to one of the metal plates 14, and the inner lining strip 8 is completely integrated into the ruler body 1. After completing the measurement of pupil width and pupillary distance, the inner lining strip 8 is pulled by the grip 7, and the slide 11 slides along the transverse groove 12 until the magnetic block 13 is attracted to another set of metal plates 14, thereby fixing the inner lining strip 8 again. At this time, the inner lining strip 8 extends out of the ruler body 1, and the patient's pupil can be measured through the measuring perforation 10. This ensures the functionality of the assessment ruler while reducing the overall volume of the assessment ruler through the telescopic method.
