It should be understood that the present utility model uses the terms "first", "second", etc. to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0042] Such as Figures 1-6As shown in the figure, an embodiment of the present application provides a blood collection device for mouse eyes, which includes a base 1; a fixing frame 2 for fixing a mouse. When the fixing clip 5 fixes the mouse, the head of the mouse extends out of the fixing frame 2; the fixing frame 2 is spaced above the base 1 and is connected to the base 1 through a first adjusting member, and the first adjusting member is used to adjust the angle of the fixing frame 2 relative to the base 1; a presser 3 is arranged at one end of the fixing frame 2 close to the head of the mouse (the presser 3 is close to the head of the mouse, so as to facilitate subsequent pressing on the chest of the mouse to accelerate the discharge of blood in the mouse body), and is movably connected to the fixing frame 2, so that the presser 3 can move in a direction close to or away from the fixing frame 2; a liquid collecting tube 4 is arranged below one side of the fixing frame 2, so that it is located below the head of the mouse; the fixing clip 5 (a common clip) is vertically spaced above the liquid collecting tube 4 and is used to fix the side cheek of the mouse; it further includes an eye extractor 6, which is composed of two mutually hinged clamping rods 61. The clamping rod 61 has a holding end and a clamping end. The holding end is used for the operation of researchers, and the clamping end is used for extracting the eyeball of the mouse. A semi-conical cylinder 62 is arranged at the clamping end of the clamping rod 61. When the two clamping rods 61 are closed, the two semi-conical cylinders 62 can enclose a conical cylinder structure. The axis of the conical cylinder structure is perpendicular to the plane where the two clamping rods 61 are located and the small-diameter end of the conical cylinder structure protrudes from the clamping rod 61.

[0043] When this embodiment works specifically, researchers first place the anesthetized mouse on the fixing frame 2 and complete the fixation of the mouse body, so that the head of the mouse extends out of the fixing frame 2 and is located above the liquid collecting tube 4. When placing the mouse, the mouse should be fixed on the fixing frame 2 in a lying position on its side, that is, one eye socket of the mouse faces downward and is located directly above the liquid collecting tube 4 (the other eye socket faces upward); then, the angle of the fixing frame 2 relative to the base 1 is adjusted through the first adjusting member, so that the body position of the mouse is in a downward-sloping posture and the head position is the lowest (as Figure 3 shown), which helps the blood to drain from the mouse body; then, the cheek on the upward side of the mouse head is clamped by the fixing clip 5. Under the clamping action of the fixing clip 5, an upward pulling force is applied to the upward side cheek of the mouse, which helps to make the downward-facing eyeball of the mouse protrude from the lower eye socket, so that researchers can remove the lower eyeball of the mouse through the eye extractor 6.

[0044] When conducting the operation of enucleating the eyeball, the researchers first separate the two clamping rods 61 by an appropriate distance, then insert the two separated semi-conical cylinders 62 into the eye socket of the mouse, and finally close the two clamping rods 61, synchronously closing the two semi-conical cylinders 62 and enclosing them into a conical cylinder structure to wrap the mouse's eyeball. The researchers then withdraw the eye extractor 6 backward to complete the enucleation of the mouse's eyeball. During the process of removing the eyeball, since the eyeball is wrapped by the conical cylinder structure formed by the two semi-conical cylinders 62, it avoids the situation of blood splashing during the eyeball enucleation process, effectively avoiding blood waste and contamination. After completing the eyeball enucleation work, the researchers press the chest position of the mouse by operating the presser 3 to further improve the blood drainage efficiency in the mouse's body and avoid the occurrence of blood remaining in the mouse's body. The blood flowing out of the eye socket drops downward into the liquid collecting tube 4 to complete the collection process of the mouse's blood.

[0045] In some embodiments of the present application, the fixing frame 2 includes a bearing part 21. The bearing part 21 is an arc-shaped semi-tubular structure for supporting the mouse's body. At least two flexible restraint members 22 are arranged at intervals on the bearing part 21. The flexible restraint members 22 are arranged perpendicular to the length extension direction of the bearing part 21. One end of the flexible restraint member 22 is fixedly installed on one side of the bearing part 21, and the other end is detachably connected to the other side of the bearing part 21.

[0046] The researchers place the anesthetized mouse in the arc-shaped semi-tubular bearing part 21 and make the mouse's head protrude outward from one end of the bearing part 21, and then cross the flexible restraint member 22 across the mouse's body and connect it to the bearing part 21 to complete the fixation process of the mouse.

[0047] In some embodiments of the present application, a first upright post 11 is provided on the base 1. The first adjusting member includes a first ball socket 12 connected to the bottom end of the bearing part 21 and a first ball head 13 that can be movably inserted into the first ball socket 12. The first ball head 13 is provided at the upper end of the first upright post 11. A first bolt 14 passing through the first ball socket 12 is threadedly installed on the first ball socket 12.

[0048] After the researchers fix the mouse on the bearing part 21, they manually move the bearing part 21 to adjust its angle relative to the base 1, and finally adjust the bearing part 21 to the state shown in Figure 3 , that is, making the mouse's body in an inclined downward posture and the mouse's head in the lowest position. After completing the adjustment of the angle of the bearing part 21, the researchers screw the first bolt 14 and make the first bolt 14 abut against the outer peripheral wall of the first ball head 13, thereby realizing reliable positioning between the first ball socket 12 and the first ball head 13, so that the mouse can stably maintain the current positioning state.

[0049] In some embodiments of the present application, asFigure 1 , Figure 2 As shown in Figure 2 , the presser 3 includes an arc-shaped pressing part 31 spanning the bearing part 21. Guide rods 32 are respectively provided at both ends of the arc-shaped pressing part 31. Guide holes 33 cooperating with the guide rods 32 are provided on the bearing part 21. An elastic member 34 is provided between the arc-shaped pressing part 31 and the bearing part 21. The elastic member 34 can be a spring or other elastic components. After the researchers complete the removal of the mouse eyeball, they press the arc-shaped pressing part 31 downward by hand and make the inner arc surface of the arc-shaped pressing part 31 press against the chest of the mouse, so as to accelerate the discharge of blood in the mouse body and improve the efficiency of blood discharge. When the blood is basically discharged, the researchers release the arc-shaped pressing part 31. At this time, the arc-shaped pressing part 31 moves upward and resets under the action of the elastic member 34.

[0050] In some embodiments of the present application, a second upright column 15 is slidably installed on the base 1. One side of the fixed clamp 5 is connected with an adjusting rod 51, and the adjusting rod 51 is installed on the second upright column 15 through a second adjusting member. In this embodiment, connecting the fixed clamp 5 with the adjusting rod 51 and installing the adjusting rod 51 on the second upright column 15 through the second adjusting member can facilitate the process of the researchers taking and placing the mouse.

[0051] Before the blood collection operation, the researchers move the second upright column 15 and make the fixed clamp 5 deviate from above the collecting tube 4, so as to facilitate the researchers to place the mouse in the fixing frame 2 and complete the fixing process of the mouse. After the fixing of the mouse is completed, the researchers move the second upright column 15 and adjust the orientation and angle of the adjusting rod 51, so that the fixed clamp 5 is above the head of the mouse and clamps the side cheek of the mouse, so that the upward side cheek of the mouse receives an upward pulling force, which helps the lower eyeball to protrude from the eye socket, facilitating the researchers to remove the mouse eyeball through the enucleator 6. After the blood collection work of the mouse is completed, loosen the fixed clamp 5 and move the second upright column 15 again, so that the fixed clamp 5 deviates from the position above the mouse head, so as to facilitate the researchers to remove the mouse from the fixing frame 2.

[0052] The second upright column 15 in this embodiment can be made of a material with a certain flexibility and bendability (such as rubber), which is more conducive to adjusting the angle and position of the fixed clamp 5.

[0053] In some embodiments of the present application, the second adjusting member includes a second ball socket 52 connected to the adjusting rod 51 and a second ball head 53 that can be movably snapped into the second ball socket 52. The second ball head 53 is provided at the upper end of the second column 15. A second bolt 54 that penetrates the second ball socket 52 is threadedly installed in the second ball socket 52. When the researcher manually adjusts the orientation and angle of the adjusting rod 51, the second ball socket 52 is synchronously slid along the outer peripheral wall of the second ball head 53. When the fixing frame 2 is adjusted to a predetermined position, the researcher screws the second bolt 54 and makes the second bolt 54 abut against the outer peripheral wall of the second ball head 53, thereby realizing the positioning between the second ball socket 52 and the second ball head 53, and enabling the fixing frame 2 to be stably maintained in the currently adjusted state.

[0054] In some embodiments of the present application, the mouse eye blood collector further includes a funnel 7 provided above the liquid collecting tube 4. The bottom end of the funnel 7 corresponds to the upper opening of the liquid collecting tube 4 and is inserted into the liquid collecting tube 4. Due to the unique structure of the funnel 7 itself, it helps to collect the blood of the mouse to prevent the blood flowing out of the eye socket from dripping onto areas outside the liquid collecting tube 4. At the same time, both the liquid collecting tube 4 and the funnel 7 are vertically slidably installed on the first column 11. After the blood collection work is completed, the funnel 7 or the liquid collecting tube 4 is vertically moved so that the bottom of the funnel 7 extends out of the liquid collecting tube 4, facilitating the researcher to take away the test tube. In this embodiment, the researcher adjusts the vertical position between the two according to the needs to facilitate the smooth progress of the blood collection process.

[0055] In some embodiments of the present application, a first mounting ring 71 and a second mounting ring 41 are vertically slidable on the first column 11. The first mounting ring 71 and the second mounting ring 41 are each provided with a third bolt 8 that is threadedly installed therethrough along its radial direction. By screwing the third bolt 8 and making it abut against the outer peripheral wall of the first column 11, the positioning of the first mounting ring 71 and the second mounting ring 41 is realized. A first rod 72 is provided along the radial direction on the outer periphery of the first mounting ring 71. The other end of the first rod 72 is connected to a first bearing ring 73 for placing the funnel 7. The inner diameter of the first bearing ring 73 is smaller than the maximum diameter of the funnel 7, so that the funnel 7 can be clamped on the first bearing ring 73. A second rod 42 is provided along the radial direction on the outer periphery of the second mounting ring 41. The other end of the second rod 42 is connected to a second bearing ring 43 for placing the liquid collecting tube 4. A rubber ring (not shown in the figure) is provided in the second bearing ring 43 and the inner diameter of the rubber ring is slightly smaller than the outer diameter of the liquid collecting tube 4, so that when the liquid collecting tube 4 is inserted into the second bearing ring 43, the positioning of the liquid collecting tube 4 is realized through the rubber ring. After the installation of the funnel 7 and the liquid collecting tube 4 is completed, the first mounting ring 71 and the second mounting ring 41 are vertically moved so that the bottom end of the funnel 7 extends into the liquid collecting tube 4, and finally the third bolt 8 is screwed to complete the positioning of the funnel 7 and the liquid collecting tube 4.

[0056] In some embodiments of the present application, such as Figure 1As shown in the figure, a guide rail 16 is provided on the base 1 of the liquid collecting pipe 4 facing away from the first upright column 11. A sliding groove 17 for slidingly installing with the guide rail 16 is provided at the bottom of the second upright column 15. A rubber damping pad is provided at the contact part between the sliding groove 17 and the guide rail 16. The settings of the guide rail 16 and the sliding groove 17 enable the second upright column 15 to be slidably installed on the base 1, and a certain degree of positioning effect on the second upright column 15 can be achieved through the rubber damping pad, avoiding the second upright column 15 from easily moving on the base 1 due to external force.

[0057] In some embodiments of the present application, as Figure 1 shown, the flexible restraint 22 is a flexible cloth. One of the free end of the flexible part and the bearing part is provided with a hook-and-loop fastener rough surface, and the other is provided with a hook-and-loop fastener hook surface that cooperates with the hook-and-loop fastener rough surface. After placing the mouse on the bearing part 21, the flexible cloth and the bearing part 21 are bonded together through the hook-and-loop fastener rough surface and the hook-and-loop fastener hook surface, thereby achieving the fixation effect on the mouse.

[0058] The working process of the present utility model is as follows: First, the scientific research personnel place the anesthetized mouse on the fixing rack 2 and complete the positioning of the mouse through the flexible restraint 22. Then, adjust the angle of the fixing rack 2 relative to the base 1 so that the posture of the mouse is inclined downward and the head of the mouse is at the lowest position. Then, clamp the side cheek of the mouse with the fixing clip 5 so that the eyeball below the mouse can protrude from the eye socket, so as to facilitate the scientific research personnel to better remove the eyeball; after completing the eyeball removal work, squeeze the chest of the mouse with the presser 3 to accelerate the speed of blood discharge from the mouse body; collect the blood in the mouse body through the liquid collecting pipe 4.

[0059] In summary, the embodiment of the present utility model provides a blood collection device for mouse eyes. In this solution, the mouse is fixed on the fixing rack 2, and the head of the mouse extends out of the fixing rack 2. The side cheek of the mouse is clamped by the fixing clip 5, so that the scientific research personnel only need to operate the eye extractor 6 to complete the blood collection process of the mouse, reducing the labor intensity and work burden of the scientific research personnel; at the same time, pressing the chest of the mouse with the presser 3 helps the blood to be discharged; through the cooperation of the semi-conical cylinder 62 and the clamping rod 61, it effectively avoids the blood splashing everywhere during the mouse eyeball removal process, avoiding blood waste and pollution.

[0060] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
