[0027] In the description of the embodiments of this application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0028] According to the present invention, a mouse experimental platform for fundus injection is provided, such as... Figures 1 to 4 As shown, the retinal injection mouse experimental table is used in mouse experiments and can assist in retinal injection in mouse experiments. The retinal injection mouse experimental table includes an experimental table body 1, a head fixing part 2, and a body fixing part 3.
[0029] In the following description, reference will be made to Figures 1 to 4 The detailed structure of the experimental table body 1, head fixation part 2, and body fixation part 3 of the mouse experimental table for fundus injection is described in detail. Furthermore, the description of the embodiment also involves two directions, namely the first direction S1 and the second direction S2, such as... Figure 1 As shown, the experimental platform body 1 can be formed into a cuboid structure. The first direction S1 can be understood as the direction from one end to the other in the length direction of the cuboid structure, and the second direction S2 can be understood as the direction from one end to the other in the width direction of the cuboid structure.
[0030] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the head fixing part 2 is located at the end of the experimental table body 1. This is to facilitate head fixation of the mouse and fundus injection. The body fixing part 3 is located in the middle of the experimental table body 1 to facilitate mouse body fixation. The body fixing part 3 includes a groove 301 for fixing the mouse body and a limiting component for limiting the mouse body. The limiting component is located on both sides of the groove 301. The groove 301 is used for placing the mouse body and also serves as a limiting component, while the limiting component further fixes the mouse body. The head fixing part 2 includes multiple fixing steps for placing the mouse head, with the multiple fixing steps facing the groove 301. In use, the mouse head is placed on the fixing steps (since there are multiple fixing steps, the mouse head can be placed on a suitable step according to the mouse's size), the mouse body is placed in the groove 301, and fixed by the limiting component to prevent the mouse from moving.
[0031] Thus, the mouse experimental table for fundus injection, through the cooperation of the table body 1, the head fixing part 2 and the body fixing part 3, enables the mouse experiment to be carried out smoothly and assists in the fundus injection of mice. The overall structure of the mouse experimental table for fundus injection is simple, lightweight, easy to use and operate, and the overall structure conforms to the ergonomics of the mouse body, which facilitates the fixation of the mouse.
[0032] Preferably, such as Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the groove 301 is disposed in the middle of the experimental table body 1 along the first direction S1, and the head fixing part 2 is disposed at one end of the experimental table body 1 in the first direction S1. In order to facilitate the fixation of the mouse body, the groove 301 is disposed in the middle of the experimental table body 1, and the user can directly place the mouse body in the groove 301. Correspondingly, the head fixing part 2 is disposed at one end of the groove 301 in the first direction S1.
[0033] Preferably, such as Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the groove 301 is smoothly connected to the bottom fixing step of the head fixing part 2. To avoid injury to the mouse, the groove 301 is smoothly connected to the head fixing part 2. The smooth connection can be achieved, for example, by providing a rounded chamfer at the connection point.
[0034] Preferably, such as Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, limiting components are disposed on both sides of the groove 301 in the second direction S2, with the two limiting components facing each other. There are two limiting components, each limiting one side of the mouse's body. The two limiting components are positioned facing each other to facilitate user adjustment.
[0035] Preferably, such as Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the limiting components may include a fixing block 302 and an adjusting block 303. The fixing block 302 is fixedly disposed on the experimental table body 1, and the adjusting block 303 is adjustablely disposed on top of the fixing block 302 to adjust the distance between the two limiting components. The fixing block 302 and the adjusting block 303 can clamp mice of different sizes to achieve the fixation of the mouse's body.
[0036] Preferably, such as Figure 1 , Figure 3 and Figure 4As shown, in this embodiment, a sliding groove 304 is provided in the middle of the adjusting block 303. The limiting component may also include a tensioning member 305 disposed in the sliding groove 304. The tensioning member 305 passes through the sliding groove 304 and is connected to the fixing block 302. When the tensioning member 305 clamps the fixing block 302 and the adjusting block 303, the adjusting block 303 remains fixed. When the tensioning member 305 releases the fixing block 302 and the adjusting block 303, the adjusting block 303 can move along the opening direction of the sliding groove 304. The tensioning member 305 may be, for example, a knob. One end of the knob is disposed on the fixing block 302 for fixing, and the other end of the knob is located on the top of the adjusting block 303 for easy adjustment by the user. Thus, the clamping method of the fixing block 302 and the adjusting block 303 is as follows: the user rotates the knob, and the head of the knob abuts against the adjusting block 303 until the fixing block 302 and the adjusting block 303 are clamped.
[0037] Preferably, such as Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the bottom of the groove 301 is arc-shaped. The arc-shaped bottom can better fit the mouse's body, making it easier for the mouse to be placed stably.
[0038] Preferably, such as Figures 1 to 4 As shown, in this embodiment, the multi-level fixed steps may include a first fixed step 201, a second fixed step 202, and a third fixed step 203 arranged sequentially from top to bottom. Here, "top" and "bottom" can refer to... Figure 1 The upper and lower parts of the middle. The area of the step surface of the third fixed step 203 is larger than the area of the step surface of the first fixed step 201 and the area of the step surface of the second fixed step 202. Since the mice commonly used in mouse experiments are all relatively small, the third fixed step 203 is commonly used as the fixed step, and therefore the area of the step surface of the third fixed step 203 is larger.
[0039] Preferably, such as Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the experimental platform body 1 is formed as a cuboid component. The cuboid component has a regular shape, which facilitates its use.
[0040] Preferably, such as Figure 2 As shown, the mouse experimental stage for fundus injection may also include an eyeball limiting ring 4. The eyeball limiting ring 4 is formed into a ring structure. When the mouse head is placed on a fixed step, the eyeball limiting ring 4 is set at the mouse's eye to limit the mouse's eye, making it convenient for the user to perform fundus injection.
[0041] Preferably, the experimental platform body 1 can be made of metal materials such as stainless steel or aluminum alloy, which has a long service life.
[0042] Preferably, the experimental platform body 1 can be made of clay, which is low in cost.
[0043] The procedure for using the mouse experimental stage for fundus injection is as follows: First, anesthetize the mouse, then place the mouse in the groove 301 with its head resting on the fixed step, so that the eyeball to be injected is exposed to the microscope. Then, place the eyeball limiting ring 4 on the surface of the mouse's eye to expose the required injection area. Then, adjust the tensioning piece 305 to adjust the adjusting block 303 to a suitable fixed position to complete the mouse fixation. After that, the next experiment can be carried out.
[0044] This mouse experimental table for fundus injection, through the cooperation of the table body, head fixation part and body fixation part, enables mouse experiments to be carried out smoothly and assists in the fundus injection of mice. The overall structure of this mouse experimental table for fundus injection is simple, lightweight, easy to use and operate, and the overall structure conforms to the ergonomics of the mouse body, which can facilitate the fixation of the mouse.
