Description

Technical Field

[0001] The utility model relates to the technical field of animal experimental motion intervention, and more specifically, to a device for preventing mice from being pinched during the motion intervention process. Background Art

[0002] Exercise intervention is an indispensable intervention method in the study of the physiological and biochemical mechanisms of exercise promoting health. Running, as an easy-to-implement sport, is a common intervention method in animal experiments. Small animal treadmills are widely used in exercise intervention because of their controllable running speed and easy operation. However, since the existing treadmill in the laboratory is shared by large and small mice, there is a gap between the tail track and the body. During the exercise intervention process, mice have been exhausted, clamped, and continuously rolled along the track and crushed by the body, causing injuries or even death. During the intervention process, for mice with relatively obese body and low exercise ability, such as diabetic and obese mice, the tail of the mouse is often clamped by the gap due to exhaustion, resulting in injury or death, which causes great inconvenience to the experiment and brings a certain degree of property loss. Therefore, this design intends to optimize the existing small animal running cover. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Refer to the instruction manual Figure 1-7 A device for preventing mice from being pinched during exercise intervention according to an embodiment of the utility model comprises a treadmill cover 1 for covering a mouse treadmill, the inner cavity of the treadmill cover 1 is provided with a treadmill partition 2 for separating a plurality of treadmill tracks, the inner cavity of the treadmill cover 1 is divided into a plurality of track chambers by the treadmill partition 2, mouse side guard structures are provided on both sides of the inner cavity of the track chamber, and a mouse tail guard structure is provided at the tail of the inner cavity of the track chamber; a hard brush 20 for driving away mice is provided on the surface of the mouse tail guard structure in an inclined shape.

[0028] The mouse side protection structure and the mouse tail protection structure are both composed of a positioning platform 3, a rebound spring hinge 4, a mouse body baffle 5, and a mouse foot baffle 6. The mouse body baffle 5 is hinged to one side of the positioning platform 3 through the rebound spring hinge 4, and the mouse foot baffle 6 is fixedly installed at the bottom of the mouse body baffle 5, wherein the rebound spring hinge 4 is composed of a hinge or hinge type structure plus a torsion spring or a spring member to form a resettable hinge. The effect presented in this scheme is that the mouse body baffle 5 is always pressed in the direction of the runway by the rebound spring hinge 4, thereby reducing the gap between the mouse foot baffle 6 and the runway, and reducing the probability of the mouse's foot being stuck;

[0029] like Figure 4 As shown, a positioning block 7 is fixedly installed on one side of the positioning platform 3 of the mouse side protection structure, and slots corresponding to the position of the positioning block 7 are opened on both sides of the inner wall of the runway chamber. The positioning block 7 is connected in the slot for fixing and disassembling the mouse side protection structure. In addition, the mouse tail protection structure is fixed in a suspended state or can also be disassembled and installed through a structure with the same function as the positioning block 7.

[0030] The bottom of the mouse foot baffle 6 is fixedly installed with a plurality of frame arms 8 for fitting the runway, and the outer wall of the frame arm 8 is rotatably connected with a roller 9. In addition, the roller 9 can be made of a water-absorbing material, and the roller 9 is set in a rolling state in order to reduce the excessive resistance of the mouse foot baffle 6 to the runway. At the same time, in order to reduce the probability of the mouse's foot being stuck, an embedded groove can be opened at the bottom of the mouse foot baffle 6, and the bottom structure such as the frame arm 8, the roller 9, and the gas-liquid discharge pipe 18 can be embedded in the embedded groove. It is only necessary to ensure that the roller 9 can contact the runway, so that the gap between the runway and the mouse foot baffle 6 can be further reduced;

[0031] In addition, the distance between the mouse foot baffle 6 and the runway is smaller than the thickness of the mouse's sole, in order to reduce the probability of the mouse's sole getting stuck in the gap. At the same time, the edge of the mouse foot baffle 6 close to the mouse's sole can be designed with a rounded and smooth structure.

[0032] A take-out port 10 and a take-out port 12 for taking mice are provided on the top of the treadmill cover 1. A magnetic stripe 1 is provided at the edges of the take-out port 10 and the take-out port 12. An integrated magnetic cover plate 11 is hingedly connected to the inner cavity of the take-out port 10 through a hinge. An independent magnetic cover plate 13 is hingedly connected to the inner cavity of the take-out port 12 through a hinge. A magnetic stripe 2 is installed at the bottom edges of the integrated magnetic cover plate 11 and the independent magnetic cover plate 13. The magnetic stripe 1 and the magnetic stripe 2 are magnetically attracted to each other, so that the integrated magnetic cover plate 11 can be opened and closed more conveniently to take mice in and out, and the magnetic design can be closed more conveniently.

[0033] Transverse slots are provided on both sides of the treadmill cover 1, and treadmill positioning plates 14 for positioning the front and rear ends of the treadmill are inserted through the transverse slots on both sides of the treadmill cover 1. Figure 3 As shown, a transverse insert block matching the transverse slot is fixedly installed at the edge of the treadmill positioning plate 14 for transverse insertion to install or remove the treadmill positioning plate 14 .

[0034] In the pipeline direction scheme, a plurality of gas-liquid injection ports 15 are fixedly installed on the top of the treadmill cover 1, and the number of the gas-liquid injection ports 15 is consistent with the number of the runway chambers. A gas-liquid delivery pipe 16 is installed in a connected state at the bottom of the gas-liquid delivery pipe 15, and a gas-liquid delivery pipe 2 17 is installed in a connected state at the top of the gas-liquid delivery pipe 16. The bottoms of the gas-liquid delivery pipe 16 and the gas-liquid delivery pipe 2 17 are both connected and equipped with a gas-liquid discharge pipe 18. The gas-liquid delivery pipe 16 is installed on the surface of the mouse body baffle 5 of the mouse tail protection structure, and the gas-liquid delivery pipe 2 17 is installed on the surface of the mouse body baffle 5 of the mouse side protection structure; a plurality of leakage holes 19 are opened at the bottom of the gas-liquid discharge pipe 18, and the leakage holes 19 are arranged on the top of the roller 9;

[0035] This solution is used to insert the liquid injection or gas injection pipeline into the inner cavity of the gas-liquid injection port 15, inject the medicine liquid or gas such as oxygen, and let it seep out from the leakage hole 19 of the gas-liquid discharge pipe 18 along the gas-liquid delivery pipe 16 and the gas-liquid delivery pipe 2 17. If it is an anti-inflammatory liquid, it can soak the drum 9 and the edge of the runway at the same time to prevent mice from being injured, infected, and other problems. In addition, the choice of gas and liquid can be adjusted according to experimental requirements.

[0036] In actual use, the treadmill cover 1 is installed on the treadmill, the front integrated magnetic cover 11 is opened, the experimental animals are collectively placed in the runway chamber, the integrated magnetic cover 11 is gently put down, the treadmill is opened, the speed is adjusted, the warm-up is started, and the speed is gradually increased to intervene according to the experimental design. The movement state of the mice is observed through the transparent treadmill cover 1. When the mice reach the middle and rear part of the treadmill, they are pushed by the oblique mouse body baffle 5 and the hard brush 20 and continue to run forward. If mice frequently stay in the middle and rear part of a runway chamber, the mouse body baffle 5 and the hard brush 20 will drive them away. The driving effect gradually weakens, and the mouse shows signs of exhaustion. It is found that the mouse cannot continue to maintain the exercise. The independent magnetic cover 13 at the middle and rear part of the runway chamber is opened to take out the mouse. After the exercise, all the mice are driven to the middle and rear part of the treadmill cover 1, and the take-out ports 12 of each runway are opened one by one to take out the experimental mice and put them into the corresponding cages to avoid the mice from crossing paths and causing grouping confusion. In addition, the treadmill used for experimental mice to run in the prior art can be placed on the top of the treadmill through the treadmill positioning plates 14 at both ends of the treadmill cover 1, so that the installation of the device and the treadmill can be realized.
