Description

Technical Field

[0001] This utility model relates to the field of laboratory animal anesthesia technology, and in particular to a mouse experimental anesthesia dosage control device. Background Technology

[0002] Mice are commonly used laboratory animals in medical research and experiments. Anesthesia is an essential step in mouse experiments to ensure the smooth progress of the experiment and the welfare of the mice. Traditional anesthesia methods typically rely on manually controlling the dosage of the anesthetic. Preparing a single dose of anesthetic for a single mouse is inefficient when multiple injections are required.

[0003] A search revealed Chinese patent application CN202220280125.4, which discloses an anesthesia injection device for laboratory mice. The device includes a syringe body with an adjusting block detachably mounted on one side via a clamping component. The adjusting block has a through hole through which an adjusting plate passes. The adjusting plate is pressed and fixed within the through hole by a clamping component. The clamping component includes a threaded rod threaded onto the adjusting block and a rotating piece fixed to one end of the threaded rod. A limit baffle is fixed to the top of the adjusting plate, and a pressure plate is slidably mounted on the bottom of the adjusting plate via a sliding component. The anesthesia injection device described in the above literature has the following shortcomings: it is inconvenient for multiple quantitative injections and requires further improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mouse experimental anesthesia dosage control device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mouse experimental anesthesia dosage control device includes a syringe, the syringe comprising:

[0007] An injection tube, in which a piston rod is movably installed, and a first graduation line is provided on the surface of the injection tube;

[0008] Side racks, which are located on both sides of the injection tube;

[0009] End plates are located on both sides of the top of the injection tube.

[0010] The needle is detachably attached to the bottom of the syringe.

[0011] A fixing bracket is mounted on the piston rod. A side rod is mounted on the fixing bracket. An opening is provided on the end plate. The bottom end of the side rod extends through the opening to one side of the injection tube.

[0012] The limiting component is installed on the outside of the injection tube. The bottom end of the side rod is L-shaped. The limiting component is used to limit the bottom end of the side rod.

[0013] The limiting component includes:

[0014] A limiting sleeve is movably positioned on the outside of the injection tube.

[0015] The slide bar is slidably connected to the inner wall of the limiting sleeve. One end of the slide bar is provided with a toothed plate, and the two toothed plates are respectively adapted to the side toothed racks on both sides of the injection tube.

[0016] A spring connects one end of the slide rod to the limiting sleeve.

[0017] A limiting frame is fixed to one outer wall of a toothed plate. A limiting plate is provided at the top of the limiting frame, and a second scale line is provided on one outer wall of the limiting frame.

[0018] The limiting block has an adjustment groove on the limiting frame, and the limiting block can be movably installed in the adjustment groove. A first fixing knob is provided on one side of the limiting block for fixing the limiting block to the limiting frame. The positions of the limiting plate and the limiting block are adapted to the bottom end of the side rod.

[0019] As a further embodiment of this utility model: one end of one of the slide rods is equipped with a first connecting frame, and one end of the other slide rod is equipped with a second connecting frame. The first connecting frame and the second connecting frame are staggered, and both the ends of the first connecting frame and the second connecting frame are provided with a lever after they cross each other's ends.

[0020] As a further embodiment of this utility model: one of the dial plates is fixed with an elastic ring, and the other dial plate is provided with a groove that matches the elastic ring. The friction between the limiting sleeve and the injection tube is greater than the weight of the limiting component.

[0021] As a further improvement of this utility model, an upper finger ring is provided at the top of the piston rod.

[0022] As a further improvement of this utility model, two side finger rings are provided at the bottom of the end plate.

[0023] As a further improvement of this utility model: the side rod is slidably installed in the fixed frame, and a second fixing knob for fixing the side rod is provided on one side of the fixed frame.

[0024] As a further improvement of this utility model, the syringe also includes a support assembly, which includes a mounting frame and a positioning post. The positioning post is mounted on the top side wall of the mounting frame, and the position of the positioning post is adapted to the side ring.

[0025] The beneficial effects of this utility model are as follows:

[0026] 1. This utility model, by setting a limiting component, enables the use of anesthetic agents by pulling the piston rod to draw in anesthetic. By pulling the two sliding rods outward, the distance between the toothed plates increases, and at the same time, the limiting frame moves to the side. The position of the limiting component is adjusted so that the limiting plate and the limiting block are located on the upper and lower sides of the bottom end of the side rod, and the position of the limiting plate is close to the top surface of the bottom end of the side rod. The position of the limiting block is adjusted to adjust the movement stroke of the side rod, so as to control the quantitative injection of anesthetic.

[0027] 2. This utility model uses a limiting component for positioning, and the position of the limiting component is adjustable. After the injection is completed, the position of the limiting component can be adjusted as needed to make the position of the limiting plate close to the top surface of the bottom end of the side rod, so as to facilitate the next injection of the same amount. It is suitable for scenarios with multiple injections.

[0028] 3. By setting up a first connecting frame, a second connecting frame and a lever plate, this utility model can make the two lever plates move closer to each other by pressing the two lever plates, thereby causing the two toothed plates to separate from the side toothed rack. This allows for free control of the movement of the limiting sleeve, making it easier to adjust the position of the limiting component and improving its practicality.

[0029] 4. By setting up structures such as elastic rings and grooves, this utility model can, when the limiting components are not used, bring the two levers close together, put the elastic ring on the other lever, and lock it into the groove, thereby keeping the two toothed plates separated from the side rack.

Detailed Implementation

[0037] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] Example 1

[0040] A mouse experimental anesthesia dosage control device, such as Figure 1-6 As shown, it includes a syringe, the syringe comprising:

[0041] The injection tube 6 has a piston rod 9 that is movably installed inside it, and a first scale line 14 is provided on the surface of the injection tube 6.

[0042] Side rack 2, which is disposed on both sides of injection tube 6;

[0043] End plate 4 is disposed on both sides of the top of injection tube 6;

[0044] Needle 7 is detachably mounted at the bottom of injection tube 6;

[0045] A fixing frame 12 is mounted on the piston rod 9. A side rod 10 is mounted on the fixing frame 12. An opening 11 is provided on the end plate 4. The bottom end of the side rod 10 extends through the opening 11 to one side of the injection tube 6.

[0046] A limiting component is installed on the outside of the injection tube 6. The bottom end of the side rod 10 is L-shaped. The limiting component is used to limit the bottom end of the side rod 10.

[0047] The limiting component includes:

[0048] Limiting sleeve 28 is movably disposed on the outside of injection tube 6;

[0049] The slide rod 27 is slidably connected to the inner wall of the limiting sleeve 28. One end of the slide rod 27 is provided with a toothed plate 23. The two toothed plates 23 are respectively adapted to the side toothed racks 2 on both sides of the injection tube 6.

[0050] Spring 22 connects one end of slide rod 27 to limit sleeve 28 via spring 22;

[0051] The limiting frame 15 is fixed to one side of the outer wall of a toothed plate 23. The top of the limiting frame 15 is provided with a limiting plate 21, and a second scale line 18 is provided on one side of the outer wall of the limiting frame 15.

[0052] The limiting block 16 and the limiting frame 15 are provided with an adjustment groove. The limiting block 16 is movably installed in the adjustment groove. A first fixing knob 17 for fixing the limiting block 16 to the limiting frame 15 is provided on one side of the limiting block 16. The positions of the limiting plate 21 and the limiting block 16 are adapted to the bottom end of the side rod 10.

[0053] By setting a limiting component, during use, the piston rod 9 is pulled to draw in anesthetic, and the distance between the two sliding rods 27 is increased by pulling them outward. At the same time, the limiting frame 15 moves to the side. The position of the limiting component is adjusted so that the limiting plate 21 and the limiting block 16 are located on the upper and lower sides of the bottom end of the side rod 10, and the position of the limiting plate 21 is close to the top surface of the bottom end of the side rod 10. The position of the limiting block 16 is adjusted to adjust the movement stroke of the side rod 10, so as to control the quantitative injection of anesthetic.

[0054] Furthermore, since positioning is achieved using a limiting component, and the position of the limiting component is adjustable, after injection, the position of the limiting component can be adjusted as needed to reposition the limiting plate 21 to be tightly attached to the top surface of the bottom end of the side rod 10, so as to facilitate the next injection of the same amount, which is suitable for scenarios requiring multiple injections.

[0055] To facilitate control of the movement of the two toothed plates 23; such as Figure 5 , Figure 6 As shown, one end of one slide rod 27 is equipped with a first connecting frame 19, and one end of the other slide rod 27 is equipped with a second connecting frame 20. The first connecting frame 19 and the second connecting frame 20 are staggered, and both the ends of the first connecting frame 19 and the second connecting frame 20 are provided with a lever 25 after they cross each other's ends.

[0056] By setting up the first connecting frame 19, the second connecting frame 20 and the lever 25, the two levers 25 can be pressed to bring them closer together, thereby causing the two toothed plates 23 to separate from the side toothed rack 2. This allows for free control of the movement of the limiting sleeve 28, making it easier to adjust the position of the limiting component and improving practicality.

[0057] To remove restrictions when not in use; such as Figure 6 As shown, a spring ring 24 is fixed on one of the dial plates 25, and a groove 26 adapted to the spring ring 24 is opened on the other dial plate 25. The friction between the limiting sleeve 28 and the injection tube 6 is greater than the weight of the limiting component.

[0058] By setting up structures such as the elastic ring 24 and the groove 26, when the limiting component is not used, after the two levers 25 are brought close together, the elastic ring 24 is put on the other lever 25 and inserted into the groove 26, so that the two toothed plates 23 are kept separated from the side toothed rack 2.

[0059] For ease of operation; such as Figure 3 As shown, an upper finger ring 5 is provided at the top of the piston rod 9.

[0060] For ease of operation; such as Figure 3 As shown, two side rings 8 are provided at the bottom of the end plate 4.

[0061] For ease of adjustment or disassembly; such as Figure 3 As shown, the side rod 10 is slidably installed in the fixing frame 12, and a second fixing knob 13 for fixing the side rod 10 is provided on one side of the fixing frame 12.

[0062] For ease of use; such as Figure 1 , Figure 2 As shown, the syringe also includes a support assembly, which includes a mounting frame 1 and a positioning post 3. The positioning post 3 is mounted on the top side wall of the mounting frame 1, and the position of the positioning post 3 is adapted to the side finger ring 8.

[0063] By setting up support components, the side ring 8 can be snapped onto the positioning post 3 as needed, thereby achieving support and fixation of the structure.

For the parts not disclosed in detail, such as specific materials and operating methods, those skilled in the art can use conventional technical means to achieve them. Since they are not the focus of the present utility model, they will not be described in detail.

[0065] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
