[0036] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0037] refer to Figures 1 to 4 The pupil pen according to the embodiment of the utility model includes:

[0038] The housing 100 has a light hole 150 formed on the bottom wall thereof;

[0039] The light assembly 300 is disposed in the housing 100 , and the lighting end of the light assembly 300 is disposed corresponding to the light hole 150 . The light assembly 300 is used to emit bright light;

[0040] The scissors 200 are slidably connected to the housing 100 so that the scissors 200 can be extended from the housing 100 or stored in the housing 100.

[0041] It is understandable that when it is necessary to measure and evaluate the size, shape, and reaction of the patient's pupil, the nurse can hold the housing 100 and turn on the light assembly 300, and align the light hole 150 on the bottom wall of the housing 100 with the patient's eyes. The bright light emitted by the light assembly 300 can shine on the patient's eyes through the light hole 150, thereby enabling the nurse to evaluate the size, shape, and reaction of the patient's pupil based on the patient's reaction to the bright light. When the scissors 200 need to be used, the nurse can slide the scissors 200 so that the scissors 200 extend from the housing 100, and the nurse can use the scissors 200. When the scissors 200 are not needed, the nurse can also slide the scissors 200 so that the scissors 200 are stored in the housing 100. When the nurse is patrolling the ward, the scissors 200 can be stored in the shell 100 of the pupil pen, so that the nurse can carry the scissors 200 while carrying the pupil pen, combining two commonly used tools into one, reducing the number of items the nurse needs to carry with her, alleviating the burden on the nurse, and saving the time spent by the nurse in looking for specific tools, which is conducive to improving the work efficiency of the nurse.

[0042] On the other hand, in the prior art, nurses often place the scissors 200 in their coat pockets. Since the scissors 200 are relatively sharp and the nurses frequently move around, they can easily cut other items in their coat pockets. Furthermore, while the nurse is searching for other items in their coat pockets, the scissors 200 can easily scratch the nurse's fingers, hindering the nurse's safety when searching. In the present embodiment, the scissors 200 can be stored within the housing 100 of the pupil pen, effectively preventing the scissors 200 from cutting other items or the nurse's fingers, thereby improving the nurse's safety when searching for items.

[0043] refer to Figure 3 and Figure 4The housing 100 includes a receiving groove 110 extending in the vertical direction. The upper end of the receiving groove 110 is formed on the top wall of the housing 100. The scissors 200 are slidably disposed in the receiving groove 110 in the vertical direction, so that the scissors 200 can slide upward and extend from the upper end of the receiving groove 110, or can slide downward and be stored in the receiving groove 110. It is understood that when the nurse needs to use the scissors 200, the nurse can push the scissors 200 in the receiving groove 110 upward, so that the scissors 200 extend from the upper end of the receiving groove 110, and the nurse can use the scissors 200. When the scissors 200 are no longer needed, the nurse can push the scissors 200 downward, so that the scissors 200 move downward and are stored in the receiving groove 110.

[0044] refer to Figures 4 to 8 The scissors 200 include a first cutting blade 210 and a second cutting blade 220 that can cut each other. The middle portion of the second cutting blade 220 is rotatably connected to the middle portion of the first cutting blade 210, so that the first cutting blade 210 and the second cutting blade 220 can be moved together or apart. The first cutting blade 210 is slidably disposed in the storage slot 110 in the vertical direction. Specifically, the upper portion of the middle portion of the first cutting blade 210 is the blade portion of the first cutting blade 210, and the lower portion of the middle portion of the first cutting blade 210 is the tail portion of the first cutting blade 210. The upper portion of the middle portion of the second cutting blade 220 is the blade portion of the second cutting blade 220, and the lower portion of the middle portion of the second cutting blade 220 is the tail portion of the second cutting blade 220. It can be understood that by rotating the second cutting blade 220 so that the second cutting blade 220 and the first cutting blade 210 are brought together, the first cutting blade 210 and the second cutting blade 220 can achieve the effect of cutting objects. The nurse drives the second cutting blade 220 to repeatedly move closer to and away from the first cutting blade 210, so that the first cutting blade 210 and the second cutting blade 220 can cut the object. The first cutting blade 210 and the second cutting blade 220 are conventional settings of the scissors 200 and will not be further described here.

[0045] When the scissors 200 need to be stored, the nurse can move the second cutting piece 220 downward, so that the first cutting piece 210 moves downward together and is stored in the storage slot 110, and then move the second cutting piece 220 close to the first cutting piece 210, so that the second cutting piece 220 can also be stored in the storage slot 110.

[0046] Specifically, the scissors 200 further include a connecting pin 270. A movable hole is defined in the middle of the second cutting piece 220. The connecting pin 270 is inserted into the movable hole and connected to the middle of the first cutting piece 210, so that the second cutting piece 220 can rotate about the connecting pin 270. It will be understood that the middle of the second cutting piece 220 is rotatably connected to the middle of the first cutting piece 210 via the connecting pin 270. The connecting pin 270 is a conventional feature of the scissors 200 and will not be further described here.

[0047] refer to Figure 5 and Figure 8 The rear end of the second shearing blade 220 is provided with a pusher 230, and an anti-slip structure 232 is provided on the outer wall of the pusher 230. Part of the pusher 230 is capable of extending into the storage slot 110, thereby bringing the first and second shearing blades 210, 220 closer together. It is understood that by pushing the pusher 230 upward or downward at the rear end of the second shearing blade 220, the nurse can either move the first and second shearing blades 210, 220 upward and out of the upper end of the storage slot 110, or move the first and second shearing blades 210, 220 downward and into the storage slot 110, making it easier for the nurse to push or store the scissors 200. Furthermore, the outer wall of the pusher 230 is provided with an anti-slip structure 232 to prevent the nurse from losing their grip when pushing the pusher 230. Specifically, the anti-slip structure 232 is a non-slip stripe extending perpendicular to the vertical direction. When the first shear 210 and the second shear 220 are placed together and stored in the storage groove 110, part of the structure of the pushing portion 230 extends into the storage groove 110, while another part of the structure of the pushing portion 230 extends out of the storage groove 110, that is, the outer wall of the pushing portion 230 and the anti-slip structure 232 extend out of the storage groove 110.

[0048] refer to Figure 5 and Figure 6 The lower end of the pusher 230 is provided with a hooking portion 231. A hooking groove 111 is formed on the housing 100. The hooking groove 111 is connected to the receiving groove 110. The hooking portion 231 can be hooked into the hooking groove 111 to bring the first and second clips 210, 220 closer together and be stored in the receiving groove 110. Specifically, the hooking groove 111 is provided below the receiving groove 110. It is understood that to store the first and second clips 210, 220, the nurse can press the pusher 230 to bring the second clip 220 closer to the first clip 210 and partially extend the pusher 230 into the receiving groove 110. The nurse can then push the pusher 230 downward, causing the first and second clips 210, 220 to move downward and be stored in the receiving groove 110. The pushing portion 230 is further pushed downward, so that the hook portion 231 on the lower end of the pushing portion 230 can be hooked into the hook groove 111. Under the action of the hook portion 231 and the inner wall of the hook groove 111, the first and second clips 210, 220 are fixed, preventing the first and second clips 210, 220 from sliding out of the storage groove 110, thereby improving the safety of the pupil pencil. That is, when the hook portion 231 is hooked into the hook groove 111, the first and second clips 210, 220 are close to each other and are stored in the storage groove 110.

[0049] refer to Figure 3 and Figure 8 The scissors 200 further include a first elastic member 240, through which the tail of the first cutting blade 210 and the tail of the second cutting blade 220 are connected. The first elastic member 240 is used to drive the tail of the second cutting blade 220 away from the tail of the second cutting blade 220. It is understandable that the first elastic member 240 can help the first cutting blade 210 and the second cutting blade 220 to automatically move away from each other after cutting is completed, that is, to open, thereby reducing the need for nurses to manually open the first cutting blade 210 and the second cutting blade 220 after each use, thereby improving the convenience of using the scissors 200.

[0050] On the other hand, when the hook portion 231 is hooked into the hook groove 111, the elastic force of the first elastic member 240 can drive the hook portion 231 to press against the inner wall of the hook groove 111, further ensuring that the first cutting piece 210 and the second cutting piece 220 will not slip out of the storage groove 110. When the scissors 200 need to be used, the nurse first presses the push portion 230 to disengage the hook portion 231 from the hook groove 111, and then pushes the push portion 230 upward to extend the first cutting piece 210 and the second cutting piece 220 from the storage groove 110.

[0051] refer to Figure 5 and Figure 8 The scissors 200 also include a second elastic member 250, which is positioned within the storage slot 110. The upper and lower ends of the second elastic member 250 are connected to the first blade 210 and the inner wall of the storage slot 110, respectively. The second elastic member 250 is used to propel the first blade 210 upward. It is understood that when the first and second blades 210, 220 are in the stored state, the first and second elastic members 240, 250 are both compressed. To use the scissors 200, the nurse first presses the pusher 230, disengaging the hook 231 from the hook slot 111. The nurse then reduces the pressure on the pusher 230. At this point, the second elastic member 250 extends, forcing the first elastic member 240 upward, allowing the first and second blades 210, 220 to quickly extend out of the storage slot 110. This allows the nurse to use the scissors 200 immediately, improving the ease of use. At the same time, the first elastic member 240 stretches, so that the tail of the second cutting piece 220 is away from the tail of the first cutting piece 210, which is convenient for nurses to use and improves the convenience of using the scissors 200.

[0052] refer to Figure 5 and Figure 7The scissors 200 further include a guide member 260 connected to the tail end of the first shearing piece 210. The guide member 260 is disposed within the receiving slot 110 and is capable of abutting against the inner wall of the receiving slot 110. The guide member 260 is provided with an escape groove 261, which is used to allow the pusher 230 to extend into the escape groove 261. It is understood that the guide member 260 abuts against the inner wall of the receiving slot 110, allowing the guide member 260 to provide guidance for the up and down movement of the first shearing piece 210, thereby allowing the first shearing piece 210 and the second shearing piece 220 to move up and down smoothly. The escape groove 261 on the guide member 260 is used to allow the pusher 230 to extend into the escape groove 261, allowing the nurse to smoothly press the pusher 230, thereby allowing the hooking portion 231 to smoothly disengage from the hooking slot 111.

[0053] To store the scissors 200, the nurse first presses the push portion 230, causing a portion of the push portion 230 to extend into the storage slot 110. This compresses the first elastic member 240 and brings the second blade 220 closer together. The nurse then pushes the push portion 230 downward, compressing the second elastic member 250 and causing the first and second blades 210, 220 to move downward and be stored within the storage slot 110. The nurse continues pressing and pushing the push portion 230 downward, causing the hooking portion 231 on the lower end of the push portion 230 to move to a position corresponding to the hooking slot 111. When the push portion 230 reaches its lowest position, the nurse releases her grip, causing the first elastic member 240 to partially extend, causing the push portion 230 to swing a short distance away from the storage slot 110. This allows the hooking portion 231 to hook into the hooking slot 111, completing the storage of the scissors 200.

[0054] refer to Figure 1 and Figure 4 The outer wall of the housing 100 is provided with a length scale 120 extending in the vertical direction. The outer wall of the housing 100 is also provided with a plurality of circular markings 130 of varying diameters, with the diameters of the plurality of circular markings 130 gradually increasing from bottom to top. It is understood that the length scale 120 engraved on the housing 100 is typically used to assist nurses in measuring pupil diameter. By comparing the scale with the patient's pupil, nurses can quickly estimate pupil size. The length scale 120 is in millimeters, making it convenient to record pupil changes under different lighting conditions. The circular markings 130 of varying diameters engraved on the housing 100 are used to quickly measure and compare pupil size. These circular markings 130 represent different diameters (in millimeters), and nurses can compare these circular markings 130 with the patient's pupil to quickly determine the patient's pupil diameter.

[0055] refer to Figure 1 and Figure 4, a pen clip 140 is provided at the upper end of the housing 100. It is understandable that the nurse can hold the pupil pen clip 140 at the collar or chest pocket of the outer coat through the pen clip 140 on the housing 100 so that the nurse can carry the pupil pen.

[0056] In the embodiment of the present invention, the light assembly 300 is a common light-emitting assembly used in a pupil pen. It primarily comprises a lamp bead 310, a circuit module, a rechargeable battery, an on / off button, and a charging port. The lamp bead 310, circuit module, and rechargeable battery are all housed within the housing 100. The lamp bead 310 is positioned corresponding to the light hole 150. The rechargeable battery is electrically connected to the lamp bead 310 via the circuit module and is used to supply power to the lamp bead 310. The charging port is electrically connected to the rechargeable battery, and the input end of the charging port is exposed on the housing 100, allowing the user to charge the rechargeable battery through the charging port. A button is movably mounted on the housing 100 and electrically connected to the lamp bead 310 via the circuit module. When the button is pressed, the lamp bead 310 emits light. Pressing the button again changes the color of the light, allowing the lamp bead 310 to illuminate in a variety of colors. Repeated presses of the button turn the lamp bead 310 off. The light assembly 300 is a common light-emitting assembly and will not be described further here.
