Abstract
Description
Technical Field
[0001] The present application relates to the technical field of biomedical experimental equipment, and in particular to a mouse numbering and marking gun. Background Art
[0002] The three common methods for labeling and numbering experimental mice include the toe amputation method, the ear tag method, and the dye marking method. The toe amputation method is used to mark the lower left and lower right toes of the mouse as numbers 1 to 10, and the upper left and upper right toes as numbers 20 to 90. Cutting off the corresponding toe represents the corresponding number, and numbers that are integers of hundreds are not marked. The ear tag method is used to mark the mouse's ears with holes or cut them into notches at the corresponding numbered positions using a punch and surgical scissors. The ones digit is marked on the left ear of the mouse, and the tens digit is marked on the right ear. The dye marking method is used to apply picric acid (yellow) or neutral red (red) to different parts of the animal with a brush. Each part represents a different number, with yellow representing the ones digit and red representing the tens digit.
[0003] In the above-mentioned method of numbering mice, cutting the toes will cause bleeding in the wounds of the mice, which is easy to cause wound infection and affect the accuracy of the experimental data of the experimental mice; the wounds caused by ear studs and cuts also have the risk of infection. At the same time, ear studs are consumables and have the problem of high consumption costs; and using a brush to color the mouse's hair will cause unclear identification over a long period of time, which has its shortcomings. Utility Model Content
[0004] In order to improve the problems caused by mouse marking, the present application provides a mouse numbering and marking gun.
[0005] The mouse numbering marking gun provided in this application adopts the following technical solution:
[0006] A mouse numbering marking gun comprises a pressure rod and a base rod, wherein the pressure rod is rotatably arranged on the base rod, the pressure rod is provided with a lower clamping plate, the base rod is provided with an upper clamping plate, the lower clamping plate and the upper clamping plate are used to clamp the ears or toes of the mouse, the upper clamping plate is provided with a tattoo mechanism, and the tattoo mechanism is used to mark the mouse body with ink, the pressure rod is provided with an upper holding rod, the base rod is provided with a lower holding rod, a limit assembly is provided between the upper holding rod and the lower holding rod, and the limit assembly is used to control the minimum distance between the upper holding rod and the lower holding rod.
[0007] By adopting the above technical solution, the experimenter first adjusts the minimum distance between the upper holding rod and the lower holding rod through the limit assembly, and then presses the upper holding rod and the lower holding rod. The upper holding rod drives the lower splint close to the upper splint through the pressure rod, so that the mouse's ear or toe is clamped by the lower splint and the upper splint. Then the tattoo mechanism injects ink into the cortex of the clamped mouse's ear or toe to form a mark number. This process will not cause traumatic wounds to the mouse, reducing the possibility of infection in the mouse's wound. At the same time, the ink will be tattooed on the mouse's body cortex, reducing the possibility of unclear identification due to a long time.

[0009] By adopting the above technical solution, the experimenters first install the mounting plate on the upper splint, then clamp the upper and lower splints on the ears or toes of the mouse, and then drive the scraper to slide back and forth through the driving member. The mouse hair located in the hair inlet groove is cut off by the edge of the scraping groove on the scraper, thereby achieving the purpose of removing the mouse hair. Then the tattoo member tattoos ink on the mouse body to achieve the marking effect.
[0010] Optionally, the driving member includes a cam rotatably arranged on the mounting plate, a return spring is supported between the scraper and the mounting plate, the return spring presses the scraper against the cam, a rotating motor electrically connected to the control system is provided on the mounting plate, and the cam is provided on the output shaft of the rotating motor.
[0011] By adopting the above technical solution, the experimenters started the rotating motor through the control system. The output shaft of the rotating motor drove the cam to rotate. During the rotation of the cam, the protrusion on the cam pushed the scraper back and forth, and the scraper reciprocated to compress the reset spring, so that the mouse hair in the hair inlet slot on the mounting plate was continuously cut off.
[0012] Optionally, the tattoo component includes an ink box detachably mounted on the upper clamping plate, the ink box is provided with a plurality of marking needles, the marking needles are connected to the ink box, and an ink filling valve is bolted to the ink box.
[0013] By adopting the above technical solution, after the hair on the mouse's ears or toes clamped by the lower and upper splints is removed, the experimenter installs the ink cartridge on the upper splint, and then re-clamps the lower and upper splints on the mouse's ears or toes. During the clamping process, the marking needle will pierce the mouse's cortex, and at the same time, the ink will flow into the mouse's cortex through the marking needle, thereby marking the mouse, and the mark will not be washed away by sweat or the like and become blurred.
[0014] Optionally, sponges are provided on opposite sides of the upper splint and the lower splint.
[0015] By adopting the above technical solution, when the upper and lower splints clamp the ears or toes of the mouse, the sponge is pressed tightly against the ears or toes of the mouse, thereby reducing the possibility of injury to the ears or toes of the mouse and helping to reduce the stress response of the mouse.

[0017] By adopting the above technical solution, the experimenter turns the adjusting screw to adjust the extension length of the adjusting screw to control the minimum distance between the upper holding rod and the lower holding rod, thereby controlling the clamping force on the mouse's ears or toes. At the same time, the supporting pressure spring makes it convenient for the experimenter to automatically separate the upper holding rod and the lower holding rod.
[0018] Optionally, a button is provided on the upper holding rod, a socket electrically connected to the button is provided on the upper clamping plate, a plug electrically connected to the rotating motor is provided on the mounting plate, and the socket is used to be plugged in with the plug.
[0019] By adopting the above technical solution, after the mounting plate is installed on the upper holding rod, the experimenter plugs the plug and the socket, thereby facilitating the experimenter to control the power on and off of the rotating motor through buttons, which is conducive to improving the convenience of operation.
[0020] Optionally, a hand-holding sleeve is provided on the lower holding rod, and a plurality of hand-holding protrusions are provided on the hand-holding sleeve.
[0021] By adopting the above technical solution, the experimenter's fingers are placed between two adjacent holding protrusions, which makes it easier for the experimenter to hold the handle, thereby reducing the possibility of accidental separation of the upper holding rod and the lower holding rod.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. The experimenter first adjusts the minimum distance between the upper and lower holding rods using the limiter assembly. Then, they press the upper and lower holding rods. The upper holding rod, through the pressure rod, drives the lower clamping plate toward the upper clamping plate, so that the mouse's ear or toe is clamped by the lower and upper clamping plates. The tattooing mechanism then injects ink into the skin of the clamped mouse's ear or toe to form a mark number. This process does not cause trauma to the mouse, reducing the possibility of infection. At the same time, the ink is tattooed on the mouse's body skin, reducing the possibility of unclear identification due to long-term marking.
[0024] 2. The experimenter activates the rotating motor through the control system. The output shaft of the rotating motor drives the cam to rotate. During the rotation of the cam, the protrusion on the cam pushes the scraper back and forth, and the scraper compresses the reset spring back and forth, so that the mouse hair in the hair inlet slot of the mounting plate is continuously cut;
[0025] 3. After the hair on the mouse's ears or toes clamped by the lower and upper splints is removed, the experimenter installs the ink cartridge on the upper splint, and then re-clamps the lower and upper splints on the mouse's ears or toes. During the clamping process, the marking needle will pierce the mouse's cortex, and the ink will flow into the mouse's cortex through the marking needle, thereby marking the mouse. The mark will not be washed away by sweat or become blurred. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The experimenter first turns the adjusting screw 83 and tightens the locking block 15 to adjust the minimum distance between the upper holding rod 6 and the lower holding rod 7. Then the experimenter squeezes the upper holding rod 6 and the lower holding rod 7 toward each other. The upper holding rod 6 drives the lower splint 3 close to the upper splint 4 through the pressure rod 1, so that the mouse's ear or toe is clamped by the lower splint 3 and the upper splint 4. During this process, the sponge 9 will continue to deform and adapt to the shape of the mouse's ear or toe.
[0037] Reference Figure 1 、 Figure 2 and Figure 3 A tattoo mechanism 5 is arranged on the upper splint 4, and the tattoo mechanism 5 is used to mark ink on the mouse body. A plug-in slot 16 is provided on the upper splint 4. The tattoo mechanism 5 includes a hair removal component 51 for removing mouse hair and a tattoo piece 52 for marking tattoos.

A driving member 515 for driving the scraper 513 to slide back and forth is arranged on the mounting plate 511, and the driving member 515 includes a cam 5151 rotatably arranged on the mounting plate 511, and a return compression spring 5152 is supported between the scraper 513 and the mounting plate 511.
[0040] Reference Figure 1 、 Figure 2 and Figure 3 The reset compression spring 5152 presses the scraper 513 onto the cam 5151. The mounting plate 511 is bolted with a rotating motor 5153 electrically connected to the control system. The cam 5151 is welded to the output shaft of the rotating motor 5153. The upper holding rod 6 is bolted with a button 10. The upper splint 4 is bolted with a socket 11 electrically connected to the button 10. The mounting plate 511 is bolted with a plug 12 electrically connected to the rotating motor 5153. The socket 11 is used to mate with the plug 12.
[0041] Before the upper and lower splints 4 and 3 clamp the ears or toes of the mouse, the experimenter first plugs the mounting plate 511 into the plug slot 16 on the upper splint 4, and plugs the socket 11 into the plug 12 at the same time, and then when the upper and lower splints 4 and 3 clamp the ears or toes of the mouse.
[0042] The experimenter presses the button 10, the rotating motor 5153 is powered on and drives the cam 5151 to rotate continuously. The protrusion on the rotating cam 5151 continuously pushes the scraper 513 back and forth to squeeze the reset spring 5152. The reset spring 5152 continuously deforms. During the sliding of the scraper 513, the mouse hair on the hair inlet slot 512 is cut off by the edge of the scraping slot 514 on the scraper 513, thereby achieving the effect of removing the mouse hair.
[0043] Afterwards, the experimenter first unplugs the plug 12 and the socket 11, then unplugs the mounting plate 511 and plugs in the ink cartridge 521, and then again clamps the upper clamp 4 and the lower clamp 3 on the part of the mouse's ear or toes where hair is removed. The marking needle 522 will penetrate the mouse's cortex, and the ink will flow through the marking needle 522 to the subcutaneous layer of the mouse, thereby achieving the purpose of marking and numbering.
[0044] The implementation principle of a mouse numbering marking gun in an embodiment of the present application is as follows: the experimenter first rotates the adjusting screw 83 and tightens the locking block 15 to adjust the minimum distance between the upper holding rod 6 and the lower holding rod 7, and then the experimenter squeezes the upper holding rod 6 and the lower holding rod 7 toward each other, and the upper holding rod 6 drives the lower splint 3 to approach the upper splint 4 through the pressure rod 1, so that the mouse's ears or toes are clamped by the lower splint 3 and the upper splint 4. During this process, the sponge 9 will continue to deform and adapt to the shape of the mouse's ears or toes.
[0045] Before the upper and lower splints 4 and 3 clamp the ears or toes of the mouse, the experimenter first plugs the mounting plate 511 into the plug slot 16 on the upper splint 4, and plugs the socket 11 into the plug 12 at the same time, and then when the upper and lower splints 4 and 3 clamp the ears or toes of the mouse.
[0046] The experimenter presses the button 10, the rotating motor 5153 is powered on and drives the cam 5151 to rotate continuously. The protrusion on the rotating cam 5151 continuously pushes the scraper 513 back and forth to squeeze the reset spring 5152. The reset spring 5152 continuously deforms. During the sliding of the scraper 513, the mouse hair on the hair inlet slot 512 is cut off by the edge of the scraping slot 514 on the scraper 513, thereby achieving the effect of removing the mouse hair.
[0047] Afterwards, the experimenter first unplugs the plug 12 and the socket 11, then unplugs the mounting plate 511 and plugs in the ink cartridge 521, and then again clamps the upper clamp 4 and the lower clamp 3 on the part of the mouse's ear or toes where hair is removed. The marking needle 522 will penetrate the mouse's cortex, and the ink will flow through the marking needle 522 to the subcutaneous layer of the mouse, thereby achieving the purpose of marking and numbering.
