Description

Technical Field

[0001] The utility model relates to the technical field of laboratory auxiliary equipment, and specifically relates to a headgear for experimental mice. Background Art

[0002] A patent with the publication number of CN218457031U in the prior art discloses a bite-proof headgear for experimental mice, which is characterized in that it includes a detachable headgear and a shoulder sleeve; the headgear is a conical structure with a wide front and a narrow rear formed by connecting the head and tail of a sheet-like body; the shoulder sleeve includes two limit rings for passing through the front limbs of the experimental mouse, and the two limit rings are connected by a connecting band, and the connecting band is detachably connected to the headgear. It can effectively prevent the mouse from gnawing and licking its own or other mice's body surface experimental parts 3 (wounds) in the same cage, avoid affecting the modeling quality and experimental results, and at the same time improve the activity comfort of the mouse and ensure the quality of the experimental process.

[0003] The above technical solution can be used when observing the survival state of experimental mice after the experiment. However, for avoiding the over-reaction of experimental mice during the experiment, its use effect is not good, because the eyes of the experimental mouse can observe the surrounding state, are easily frightened, and have an over-reaction, which affects the experimental operation. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that: when the headgear of the prior art is used in the experiment, the eyes of the experimental mouse can observe the surrounding state, are easily frightened, have an over-reaction, and affect the experimental operation.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A headgear for experimental mice includes a conical headgear formed by curling a sheet-like sector body with the head and tail connected. Leg limit holes are opened on both sides of the conical headgear.

[0007] A fork is opened at the middle position near the bottom of the top of the conical headgear, and the fork extends to the position near the middle of the conical headgear.

[0008] Furthermore, straps are symmetrically sewn at the position near the bottom of the back of the conical headgear and at the position of the fork on its front.

[0009] Furthermore, the two ends of the sheet-like sector body are sewn or adhered by a magic tape in one way.

[0010] Working principle and beneficial effects: By taking advantage of the biological characteristics that laboratory mice prefer darkness and are quieter in narrow spaces, the device completely wraps the head of the laboratory mouse, preventing it from observing the surrounding environment visually, solving the problem of stress response caused by visual stimulation, and also avoiding biting the operator. Its front feet are covered by a conical headgear, preventing it from moving freely and also avoiding the problem of escape. The device has a simple structure, low production cost, and is easy to promote. Brief Description of the Drawings

[0017] As Figure 1-2 shown,

[0018] Embodiment

[0019] An experimental mouse headgear, comprising a conical headgear 1 formed by curling a fan-shaped body of a sheet end to end. Leg limiting holes 2 are opened at positions on both sides of the conical headgear 1 near its bottom; a fork 3 is opened at a position near the bottom in the middle of the top of the conical headgear 1, and the fork 3 extends to a position near the middle of the conical headgear 1. Straps are symmetrically sewn at positions on the back of the conical headgear 1 near the bottom and at positions on its front face located at the fork 3.

[0020] When in use, the head of the experimental mouse is located at the innermost part of the conical headgear 1, its legs extend out from the leg limiting holes 2, and then the straps are fastened, and that's all.

[0021] This device utilizes the biological characteristics that experimental mice like darkness and are quieter in narrow spaces. It completely wraps the head of the experimental mouse, making it unable to observe the surrounding environment with its sight, solving the problem of stress response caused by visual stimulation, and can also avoid biting the operator. Its front feet are covered by the conical headgear and cannot move freely, also avoiding the problem of its escape. This device has a simple structure, low manufacturing cost, and is convenient for popularization.

[0022] Example 2: Leg limiting holes 2 are respectively opened on both sides of the conical headgear 1 near its top and bottom. The four limbs of the experimental mouse can be exposed, and then the entire conical headgear 1 is lifted to make the experimental mouse suspended, and then the experimental operation is carried out.
