Technical Field

The invention relates to the technical field of physiological experiments, in particular to a mouse experimental device.

Background

In animal physiology experiments, mice are frequently used experimental animals. Experiments in mice typically involve administration, dissection, etc., and in doing so, the mice need to be immobilized. In the traditional method, an experimenter manually holds a mouse to carry out an experiment, and the mouse is agile in action, difficult to hold and difficult to operate.

In order to solve the above problems, a series of mouse fixing devices have been proposed in the prior art, and many of these devices are designed to enclose a mouse in a fixed cylinder, and to pull out the head, limbs, etc. of the mouse for administration, dissection, etc. However, the mice are only relatively fixed, the mice can also wriggle in the administration process, and the head and the four limbs of an experimenter are manually fixed to ensure that the experiment can be smoothly carried out; particularly, when the experiment operation is carried out on the abdomen of the mouse, the peristalsis of the mouse has great influence on the abdomen experiment operation.

Disclosure of Invention

The invention aims to provide a mouse experimental device to solve the problem that the operation is influenced because a mouse is not stably fixed in the conventional fixing mode.

In order to achieve the purpose, the invention provides the following technical scheme:

the utility model provides a mouse experimental apparatus, includes fixed case, fixed case both ends opening, and the inner space of fixed case reduces from the one end to the other end of fixed case gradually, slides along its length direction on the curb plate of fixed case and is provided with a plurality of fixed blocks that are used for fixed mouse four limbs, is provided with the fixed plate that is used for fixed mouse head in the fixed case, and the fixed plate slides along the length direction of fixed case and sets up and the fixed plate can compress in vertical direction.

The principle of the scheme is as follows:

the fixed box is used for placing the mouse, and the fixed block is used for the four limbs of fixed mouse, and the fixed plate is used for the head of fixed mouse. The inner space of the fixing case is gradually reduced from one end to the other end of the fixing case, and the fixing plate can be compressed in a vertical direction. After the head and the four limbs of the mouse are fixed, the fixing plate is pulled to move to the small-diameter end from the large-diameter end of the fixing box, so that the fixing plate can be compressed, and the head of the mouse can be clamped. Meanwhile, the space in the fixed box is reduced, the moving space of the mouse is reduced, and when the mouse is moved to the small-diameter end, the mouse can be compressed, so that the wriggling of the mouse is reduced.

The beneficial effect of this scheme does:

1. the four limbs and the head of the mouse are respectively fixed by the fixing block and the fixing plate, so that the four limbs or the head of the mouse do not need to be manually held during administration, and the operation is convenient.

2. The mouse is pulled into the small-diameter end of the fixed box, so that the mouse can be extruded into the fixed box, the moving space of the mouse is reduced, the mouse is prevented from creeping, and the fixing stability and the reliability of the mouse are improved.

3. Can compress fixed plate chucking mouse head with the path end of mouse pulling to fixed case, can also compress tightly the mouse health simultaneously, kill two birds with one stone, easy operation.

Further, the fixed plate includes punch holder and lower plate, all is provided with the centre gripping groove on punch holder and the lower plate, and the centre gripping groove sets up relatively and the lock forms the centre gripping hole, is connected with the spring between punch holder and the lower plate. The clamping grooves are buckled to form clamping holes for clamping the neck of the mouse, when the fixing plate moves integrally, the space of the fixing box is reduced, and the spring is compressed, so that the upper clamping plate and the lower clamping plate can be closed, the compression of the fixing plate is realized, and the head of the mouse is clamped; the spring is used for connecting the upper clamping plate and the lower clamping plate and also used for providing a space for compressing the upper clamping plate and the lower clamping plate.

Furthermore, all be provided with the spout along length direction on the roof of fixed case and the bottom plate, upper plate top both ends and lower plate bottom both ends all be provided with spout complex slider. The sliding block is matched with the sliding groove to realize the sliding of the upper clamping plate and the lower clamping plate, and the structure is simple; the spout can also give the removal direction of punch holder and lower plate, improves sliding stability.

Furthermore, the slider is connected with a ball in a rotating manner, and the ball is connected in the sliding groove in a rolling manner. The sliding is realized by rolling the balls in the sliding groove, so that the upper clamping plate and the lower clamping plate can slide more smoothly.

Further, be provided with the hole of placing that supplies mouse four limbs to pass on the fixed block, place hole one side intercommunication and have the fixed orifices of bar, the width of fixed orifices is less than the diameter of placing the hole. The diameter of the placing hole is larger, so that four limbs of the mouse can conveniently pass through the placing hole, and the width of the fixing hole is small, so that the four limbs of the mouse can be tightly clamped; pass the mouse four limbs from placing the hole, then remove to fixed downthehole can fix the mouse four limbs, simple structure, convenient operation.

Further, be provided with the bar hole along length direction on the curb plate, fixed block top and bottom are provided with the bolt, and bolt sliding connection is downthehole at the bar. After fixing the mouse four limbs in the fixed block, the fixed block slides in the bar downthehole, compares and directly slides the mouse four limbs card in the bar downthehole, and this kind of mode can avoid the mouse four limbs to be scratched.

Furthermore, a driving rod is connected to the lower clamping plate and is perpendicular to the lower clamping plate, and a baffle plate for blocking the mouse is arranged on the driving plate. The driving rod is used for holding by an experimenter to pull or push the fixing plate, so that the fixing plate can be conveniently slid; the baffle is used for blocking the mouse, and the mouse is prevented from separating from the fixed plate when the fixed plate moves.

Further, an opening for exposing the abdomen of the mouse is arranged on the bottom plate. The opening is convenient for the mouse to be compressed and then expose out of the abdomen, so that experimental operations such as drug administration or dissection and the like are carried out on the abdomen, and the functions and the application range of the invention are expanded.

Furthermore, the fixed box is made of transparent materials. The arrangement is convenient for an experimenter to observe the condition of the mouse.

Furthermore, the fixed holes and the inner wall of the clamping groove are provided with protective pads. The protection pad is arranged to reduce the friction between the neck and four limbs of the mouse, so that the mouse is prevented from being injured.
