When conducting scientific experiments on animals, it is necessary to quickly set up experimental platforms that meet the flexibility and versatility requirements of scientific experiments.

[0003] Currently, the ophthalmology industry lacks dedicated experimental equipment for animal ophthalmic testing. Human eye testing equipment is often used for animal testing or medical research. Furthermore, animal testing requires manual restraint, or the restraint devices used are unstable, leading to cumbersome operations. For example, see... Figure 1 Using a phone holder clamped to the desktop where the testing device was located, the small animal was strapped to the front of the phone holder. Image acquisition was performed using ophthalmic medical equipment. The holder lacked rigidity, causing the device to wobble easily when moved left and right. Each shot required waiting for the holder to stabilize, making it inconvenient and inefficient. Alternatively, see... Figure 2 A double-folding bracket was used to hold the test equipment on the table. The small animal was tied to the front of the bracket. The bracket position needed to be constantly adjusted when the animal's left and right eyes were being photographed. The equipment was very prone to shaking when it was moved left and right. Each photograph also required waiting for the bracket to stabilize before it could be taken, resulting in low data collection efficiency.

[0004] Therefore, there is an urgent need for an ophthalmic medical device accessory and ophthalmic medical device to solve the above-mentioned technical problems. Utility Model Content

[0043] like Figures 3 to 11As shown, this embodiment provides an accessory for an ophthalmic medical device, including a clamp 200 and a support platform 300. One or both ends of the clamp 200 have a first recess 210, which engages with a forehead support 100 of the ophthalmic medical device. The first recess 210 and the support platform 300 form a complete or partial enclosure of the forehead support 100, and the clamp 200 is fixedly connected to the support platform 300 to restrict all or part of the relative movement of the support platform 300 relative to the forehead support 100. This relative movement may include upward relative movement, downward relative movement, or relative rotational movement. For example, after the clamp 200 and the support platform 300 are fixedly connected, the support platform 300 is fixed at a specific position on the forehead support 100, and the support platform 300 cannot move up or down. Alternatively, after the clamp 200 and the support platform 300 are fixedly connected, the support platform 300 is secured to the ophthalmic medical device's forehead support bracket 100 under the action of gravity. Alternatively, by applying a certain downward pressure to the support platform 300, it is clamped or secured to the ophthalmic medical device's forehead support bracket 100; that is, the support platform 300 can move downwards under the action of an external force. The support platform 300 is used to support or place the animal to be tested for ophthalmic measurements. In some possible implementations, the first recess 210 and the support platform 300 can form a clamp to enclose the forehead support 100 of the ophthalmic medical device. The support platform 300 is fixed relative to the forehead support 100 by the clamp 200 and the support platform 300. Alternatively, the corresponding structure of the first recess 210 and the support platform 300 forms a support, allowing the support platform 300 to be fixed to the forehead support 100 under gravity. Alternatively, the first recess 210 and the support platform 300 have a protruding limiting portion that cooperates with the forehead support 100 to limit the vertical displacement of the support platform 300. Preferably, the first recess 210 and the support platform 300 that cooperates with it can be made entirely or partially of an elastic material, allowing for better fixation under the weight of the support platform 300. The support platform 300 is used to support or place the animal to be tested. For example, the ophthalmic medical device forehead support 100 may include two symmetrically arranged support columns 110, a forehead support portion 120 and a chin support 130. The forehead support portion 120 is installed on the top of the two support columns 110, and the chin support 130 is installed on the support frame of the ophthalmic medical device forehead support 100 and is located in the middle of the two support columns 110.

[0044] In the aforementioned ophthalmic medical device accessory, the first recess 210 and the support platform 300 form a complete or partial enclosure of the ophthalmic medical device forehead support 100, and the clamp 200 is fixedly connected to the support platform 300, which can restrict the relative movement of the support platform 300 with respect to all or part of the ophthalmic medical device forehead support 100, so that the support platform 300 is stably fixed on the ophthalmic medical device forehead support 100. Its installation is stable and not easy to shake, which improves the accuracy and efficiency of data collection.

[0045] Optionally, the support platform 300 includes two ends with different widths, allowing one end to be inserted into the forehead support 100 of the ophthalmic medical device, while restricting the other end from entering. Further, the end of the support platform 300 near the inner side can be inserted into the inner side of the forehead support 100 of the ophthalmic medical device. During insertion, the support platform 300 is positioned on top of the clamp 200, forming a support or limiting relationship, thereby improving the reliability of the support platform 300.

[0046] Preferably, the support platform 300 is provided with an indicator 600 or a groove structure, the extension direction of the indicator 600 or the groove structure forming an angle of 30°±10° with the axial direction of the support platform 300, used to indicate the placement position of the experimental animal or to place the test animal, facilitating rapid determination of the experimental position of the test animal or rapid placement of the test animal. In some possible embodiments, the groove structure on the support platform 300 is used to place the test animal, such as a mouse. The groove structure has an inclined placement surface, which is inclined at 30°±10° based on the support platform 300, so that the test animal is placed inclined along the placement surface, and the eyes of the test animal are aligned with the test end of the experimental equipment. Furthermore, the groove structure also has another arc surface, which is opposite to the placement surface, used to support the mouse and place it stably in the groove structure. Furthermore, the arc surface can be provided with a stepped structure, which allows for fine-tuning of the angle of the placement position of the test animal.

[0047] Optionally, the ophthalmic medical device accessory also includes a placement module 500, which can be detachably fixed or placed on the support platform 300. The placement module 500 includes a sliding base plate 510 and a V-groove structure 520 mounted on the sliding base plate 510, on which the animal to be tested is placed. For example, the animal to be tested can be a zebrafish.

[0048] Furthermore, the placement module 500 also includes a handle 530 disposed on the sliding base plate 510. The handle 530 is used to move the placement module 500, thereby improving the convenience of operation.

[0049] Optionally, the marking part 600 is set as an arrow, which is prepared by laser engraving, or by sticker affixing, or by screen printing; when the supporting platform 300 is made of metal, the arrow is set as a soft magnetic arrow, which is magnetically attracted to the supporting platform 300.

[0050] Alternatively, the marking section 600 may be configured as a pointer protrusion, which is slidably mounted on the support platform 300. See also Figure 11 Two markers 600 are symmetrically arranged along the central axis of the support platform 300 to acquire images of the left and right eyes of the animal to be tested, respectively.

[0051] Furthermore, the ophthalmic medical device accessory also includes a connecting structure 700, through which the support platform 300 abuts against the bottom of the ophthalmic medical device's forehead support 100 or the chin support 130 of the ophthalmic medical device's forehead support 100. The length of the connecting structure 700 is adjustable, allowing for the fixation of the support platform 300. This arrangement further enhances the stability of the support platform 300 against the ophthalmic medical device's forehead support 100.

[0052] Furthermore, the connecting structure 700 includes a threaded component and an elastic component fitted onto the threaded component. One end of the threaded component abuts against the bottom of the forehead support bracket 100 or the chin support bracket 130 of the ophthalmic medical device, and the other end of the threaded component is screwed to the support platform 300. The threaded component can provide support for the support platform 300, while the elastic component can buffer the force between the support platform 300 and the threaded component.

[0053] Optionally, the support platform 300 includes a support plate 310 and a connecting plate 320 fixedly connected to each other perpendicularly. The support plate 310 and the connecting plate 320 are fixedly connected, and the connecting plate 320 is also detachably fixedly connected to the clamp 200, so that the support platform 300 is fixed on the ophthalmic medical device forehead support 100. The support plate 310 is used to support or place the animal to be tested. The support plate 310 and the connecting plate 320 are fixed perpendicularly to each other. This arrangement makes the connecting plate 320 and the clamp 200 parallel to each other, which facilitates the detachable fixed connection between the connecting plate 320 and the clamp 200.

[0054] In this embodiment, the connecting plate 320 and the clamp 200 are connected by a fastener 400. The connecting plate 320 has a connecting groove 321 with a connecting hole. The fastener 400 fixes the clamp 200 to the connecting plate 320 through the connecting hole. After the fastener 400 is installed on the connecting plate 320, its end is received in the connecting groove 321 to prevent external components from colliding with the fastener 400 and damaging its installation stability.

[0055] This utility model also provides an ophthalmic medical device, including an ophthalmic medical device forehead support 100 and the aforementioned ophthalmic medical device accessories, which has high acquisition accuracy and acquisition efficiency.
