Technical Field
[0001] The utility model relates to the technical field of mouse experimental auxiliary tools, in particular to a mouse fixing bracket suitable for an eye experimental operation mode. Background Art
[0002] According to market research and actual laboratory use, there are many types of fixed brackets for mouse experiments on the market, but there is no fixed bracket specifically used to fix the mouse face, for eye and periorbital modeling, physical therapy or drug administration experiments. At the same time, the existing mouse fixation products have the following characteristics: long experiment time, difficult to fix the eye experiment site, and weak physiological limit tolerance of experimental mice. Existing products are used to fix the body, but cannot fix the head and face of the mouse; when using existing products for eye experiments, the mouse head will struggle and move due to external stimulation, and the experiment is difficult to operate and cannot be carried out normally. It is obviously unrealistic to use artificial methods to fix the mouse's eyes for a long time in the laboratory. Usually, the mouse's neck bones and muscles are fixed with ropes to control the mouse's micro-movement, or the experimental operation is performed directly after anesthesia. These methods cause great damage to the experimental animals and also lead to deviations in the experimental results.
[0003] In recent years, with the increase in various intelligent video devices such as smart phones, smart glasses, smart helmets, and smart screens, the number of people with eye diseases has gradually increased, especially teenagers. This market demand has led to an upward trend in eye drug experiments. Therefore, there is an urgent need to design a mouse fixation bracket suitable for eye experiment operation modes to provide product guarantees for the normal, smooth and efficient conduct of experiments.

[0031] In the accompanying drawings, the components represented by the reference numerals are listed as follows:
[0032] 1. Head fixing device; 2. Body fixing device; 3. Flexible restraint belt; 11. Flexible restraint plate for face; 12. U-shaped groove for neck; 13. Support bar; 121. U-shaped groove; 21. Body fixing body. DETAILED DESCRIPTION
[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0034] like Figure 1-2 As shown, the utility model provides a mouse fixing bracket suitable for an eye experiment operation mode, comprising: a head fixing device 1 and a body fixing device 2, wherein the head fixing device 1 is installed on one side of the length direction of the body fixing device 2, and for long-term use, the head fixing device 1 and the body fixing device 2 can be fixed on a workbench by screws or the like, and for temporary use, the head fixing device 1 and the body fixing device 2 can be fixed by double-sided tape or the like, without further limitation herein.
[0035] In this embodiment, multiple flexible restraint belts 3 are arranged in pairs on the head fixing device 1 and the body fixing device 2, and the body, the top of the head and the top of the nose of the mouse are fixed by the flexible restraint belts 3. The problem that similar products cannot fix the movement of the mouse's head is solved, ensuring the smooth progress of eye experiment operations and the accuracy and repeatability of experimental results. Specifically, the flexible restraint belt 3 is made of flexible materials such as fiber or pure cotton. After the flexible materials are tied, they can be cross-fixed with metal clips, plastic clamps, etc., which is simple to operate and avoids tearing injuries to the mouse, ensuring that the mouse is emotionally stable during the test stage.
[0036] Specifically, a flexible facial restraint plate 11 is provided on the head fixing device 1. The flexible facial restraint plate 11 is a plastic plate that fits the mouse's face. After the mouse is placed on the mouse fixing bracket in a prone position, the mouse's body is fixed by the flexible restraint belt 3 on the body fixing device 2, and the flexible facial restraint plate 11 is pressed by hand to fit and cover the mouse's face. The flexible restraint belt 3 on the head fixing device 1 is used to fix the mouse's head. The force-bearing area of the flexible facial restraint plate 11 and the mouse's face is increased. By decomposing the force, the force of the mouse's neck bones and muscles is resisted. The flexible material avoids tearing the mouse's hair, causing little harm to the mouse, thereby ensuring that the mouse is emotionally stable during the test phase.
[0037] This fixed bracket can be used for rats or mice in eye experiments. The materials of the fixed bracket are mainly wood, flexible materials such as rubber, chemical fiber and other lightweight materials, and no personal injury will be caused by the falling of the fixed bracket; the fixed bracket itself does not use electric devices and there is no electrical (for example: battery) fire risk; the device components have no sharp points and edges and will not scratch people or mice; the device itself has no prestress and there is no risk of physical impact due to loss of control of prestress.
[0038] The body and head of the mouse are fixed by the mouse fixing bracket, and the face flexible constraint plate 11 expands the constraint area with the mouse face, thereby offsetting the force of the mouse neck bone and muscle micro-movement, solving the problem that when fixing the mouse head micro-movement in the current laboratory, if the thread and rope are loosely fixed, the fixation effect cannot be achieved, if the fixation is tight, the mouse suffocates and dies, and if the mouse head micro-movement is artificially constrained, human resources are wasted and the experimental efficiency is reduced. It fills the gap in the current market that there is no head fixing device 1 but only body fixing device 2; because the current laboratory generally uses ropes to tighten the mouse neck to resist the force of the mouse neck bones and muscles, due to the long experiment time, tightening the mouse neck for a long time will cause damage to the experimental animal, and the face flexible constraint plate 11 reduces the damage to the experimental animal. Without destroying the structure of the body fixing device 2 itself, the head fixing device 1 can be used in combination with the mouse body fixing device 2. Due to the stress response of the mouse, the neck is not fixed with the rope, and the experimental preparation stage takes a long time. In addition, the artificial fixation of the mouse head causes an increase in labor costs. The use of this fixing bracket improves the experimental efficiency, and the head fixing device 1 has an integrated structure, which is simple and easy to operate, saving a lot of experimental preparation time.
[0039] like Figure 1-2 As shown, in a preferred embodiment, the body fixing device 2 includes: a body fixing body 21, and a plurality of groups of flexible restraint belts 3 are arranged in pairs at intervals along the length direction of the body fixing body 21, wherein the flexible restraint belts 3 are arranged on the upper end surface of the body fixing body 21. In this embodiment, the body fixing body 21 is made of lightweight materials such as wood, and is a rectangular parallelepiped as a whole. The pairs of flexible restraint belts 3 are respectively fixed to the upper end surface of the body fixing body 21 by screws. Specifically, in the actual experimental process, the number of flexible restraint belts 3 can be set as needed, and no limitation is made here. The body fixing body 21 and the flexible restraint belts 3 are used to fix the mouse body to prevent the movement of the mouse from affecting the experimental operation.
[0040] like Figure 1-2 As shown, one side of the face flexible restraint plate 11 in the length direction is arranged on the upper end surface of the body fixing body 21, and the other side of the face flexible restraint plate 11 in the length direction is arranged to extend out of the end of the body fixing body 21. The design of the face flexible restraint plate 11 extending out of the body fixing body 21 facilitates the operator to directly operate the face flexible restraint plate 11 to fit the mouse's face, thereby achieving fixation of the mouse's face, and improving the convenience of operation.
[0041] like Figure 1As shown, in a preferred embodiment, the head fixing device 1 also includes: a neck U-shaped groove 12, the neck U-shaped groove 12 is arranged along the width direction of the body fixing body 21, and the length of the neck U-shaped groove 12 is slightly larger than the width dimension of the body fixing body 21, the neck U-shaped groove 12 is arranged on the upper end surface of the body fixing body 21, and one side of the neck U-shaped groove 12 in the width direction abuts against the side surface of the face flexible constraint plate 11; in this embodiment, the neck of the mouse is fixed by the neck U-shaped groove 12, compared with the existing method of fixing the neck of the mouse with a rope, resisting the force of the bones and muscles of the mouse neck, and preventing micro-movement of the mouse head; preventing micro-movement of the mouse head by the neck U-shaped groove 12 can reduce the damage to the experimental animals in the experiment.
[0042] Specifically, an inwardly concave U-shaped groove 121 is provided on the neck U-shaped groove 12. When conducting experiments, the mouse adopts a prone position, and the mouse's neck is confined in the U-shaped groove 121. The U-shaped groove 121 supports the neck of the experimental mouse, and the design of the U-shaped groove 121 can fix the mouse's neck and form a fulcrum to transmit the force applied to this part. During the transmission process, the resistance of the material and structure and the restraint force during wrapping offset the strength of the mouse's neck bones and muscles.
[0043] In some feasible embodiments, the length dimension of the neck U-shaped groove 12 is set to 160mm and the height dimension is 4mm; the lateral opening dimension of the U-shaped groove 121 is 6mm and the longitudinal opening depth is 2mm. This dimension meets the daily experimental requirements of rats or mice, so that the U-shaped groove 121 can fit the neck of the mouse tightly during the experiment without causing compression or discomfort; it can be imagined that the size of the neck U-shaped groove 12 can be set according to the actual experimental requirements. At the same time, combined with the specific dimensions, it can be seen that the bottom end of the U-shaped groove 121 is higher than the upper end surface of the body fixing body 21, so that the U-shaped groove 121 has a supporting effect on the mouse neck, which improves the comfort of the experiment; at the same time, it protects the mouse's neck, and avoids tightening the mouse's neck when the restraining force is all concentrated on the neck when the rope is fixed, causing the mouse to suffocate and die, resulting in the failure of the experiment.
[0044] In the preferred solution, a flexible layer is also provided on the inner wall of the U-shaped groove 121, and the flexible layer fits the neck of the experimental mouse during the experiment. The flexible layer is made of flexible material, wherein the flexible material can be rubber or leather, etc., which is not limited here. The mouse neck is placed in the U-shaped groove 121 of the neck U-shaped support groove, and the inner wall of the U-shaped groove 121 is made of flexible materials such as leather or rubber to fix the mouse neck while protecting the neck from damage; the setting of the flexible layer improves the comfort of the mouse during the experiment, helps to reduce the stress response of the experimental mouse, and ensures the accuracy of the experimental results.
[0045] like Figure 1-2As shown, in a preferred embodiment, the neck U-shaped groove 12 and the face flexible constraint plate 11 are arranged on the same central axis; specifically, a support bar 13 is arranged at the central axis of the lower end surface of the face flexible constraint plate 11, and the support bar 13 extends from the end of the body fixing body 21 to the side of the face flexible constraint plate 11 away from the neck U-shaped groove 12, wherein the face flexible constraint plate 11 is bonded to the support bar 13 along the central axis with high-strength glue, and one end of the support bar 13 is connected to the end of the body fixing body 21 with screws or mortise and tenon joints corresponding to the center point of the neck U-shaped groove 12. The support bar 13 is made of wood material and is fixedly connected to the body fixing body 21 to form a T shape.
[0046] In the above scheme, corresponding to the position of the center point of the U-shaped groove 12 on the neck, the body fixing body 21 and one end of the support bar 13 are connected by screws or mortise and tenon joints to form a T-shape, and the T-shaped structure ensures that the eye experiment head fixing device 1 is firmly connected; and the face movable flexible constraint plate is fixed on the support bar 13 along the central axis, and the surface and the bar form a whole, and the leverage effect of the support bar 13 offsets the bone and muscle strength of the mouse neck.
[0047] like Figure 1-2 As shown, the end where the face flexible constraint plate 11 abuts against the neck U-shaped groove 12 is defined as the wide end of the face flexible constraint plate 11. The two ends of the wide end extend in an arc-shaped trajectory in the direction away from the neck U-shaped groove 12 and gradually accommodate at one end point. The specific shape of the face flexible constraint plate 11 is similar to half an ellipse. In some feasible embodiments, the overall size of the face flexible constraint plate 11 is set to: length * width * height = 100mm * 2mm * 2mm; in this embodiment, the face movable flexible constraint plate is also made of flexible materials, such as rubber or leather. Through the pressure of the human hand, it can wrap the mouse's face according to the shape of the mouse's face, expand the force-bearing area, and will not cause damage to the mouse's face; the force-bearing area is increased, and most of the force of the mouse's neck bones and muscles is decomposed to the face flexible constraint surface where the face flexible constraint plate 11 contacts the mouse's face by force decomposition.
[0048] In the above scheme, the mouse's face is wrapped with the flexible facial constraint plate 11. The supporting force and material strength of the support bar 13 are superimposed on the wrapping prestress of the flexible facial constraint plate 11. A lever effect is formed through the support bar 13. By decomposing the force, the force of the mouse's neck bones and muscles is resisted. The flexible material avoids tearing the mouse's hair, causing little harm to the mouse, thereby ensuring that the mouse is emotionally stable during the test phase.
[0049] like Figure 1-2As shown, in a preferred embodiment, two pairs of flexible restraint belts 3 are arranged in pairs on the flexible restraint plate 11 for face, that is, two groups of four flexible restraint belts 3, the pairs of flexible restraint belts 3 are symmetrically arranged about the central axis of the flexible restraint plate 11 for face, the two wings of the flexible restraint plate 11 for face are connected to the flexible restraint belts 3 by sewing, the first group of flexible restraint belts 3 are arranged on the upper end surface of the flexible restraint plate 11 for face, close to the wide end of the flexible restraint plate 11 for face, and are used to wrap the fan-shaped restraint plate for face, and are fixed to the top of the mouse's head by a plastic clamp or a metal frame during the experiment; the second group of restraint belts are arranged at intervals from the wide end of the flexible restraint plate 11 for face, and when specifically arranged, another pair of flexible restraint belts 3 are arranged at 1 / 2 of the distance from the wide end, and are used to wrap the fan-shaped restraint plate for face, and are fixed to the mouse's nose by a plastic clamp or a metal frame during the experiment.
[0050] In this embodiment, the head fixing device 1 adopts an integrated design. The mouse experiment head fixing device 1 is composed of a neck U-shaped groove 12, a face flexible constraint plate 11, a support bar 13 and two sets of flexible constraint belts 3. The above components are fixedly connected to each other to form a whole, so that no additional assembly is required during use.
[0051] In this embodiment, the two groups of constraint strips on the two wings of the facial flexible constraint plate 11 are made of flexible materials such as pure cotton or chemical fiber. The fulcrum of the neck U-shaped groove 12, the fixing points of the first group of flexible constraint strips and the fixing points of the second group of flexible constraint strips form a triangle. The stabilizing effect of the triangle is used to ensure the stability of the wrapping prestress of the facial flexible constraint plate 11, offset the force of the mouse's neck bones and muscles, and ensure that the mouse's head does not undergo micro-movement.
[0052] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
