Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical experimental equipment, in particular to a limb recovery evaluation device for medical experimental animals. Background Art
[0002] Medical surgery experiments and pharmacology experiments usually require a lot of practical verification to screen and determine effective solutions. However, due to the limitations of human ethics, various experiments directly used on humans are not accepted by the secular world. Therefore, experimenters choose mammals with similar genetic structures to humans, such as white mice or nude mice, as experimental subjects instead of humans.
[0003] After experimental animals undergo surgery or are given medication, their healing or recovery needs to be observed. For example, the integration and coordination of the motor functions of the experimental animals' limbs can be evaluated by letting them pass through a narrow passage. The existing experimental device only uses a bracket to raise the wooden piece that serves as a narrow passage to a certain height, and then lets the experimental animals pass through for testing. This simple experimental device has the following problems: first, there are no obstructions around the device, and the experimental animals have a greater chance of running away or getting injured if they fall from the wooden piece; second, affected by the individual nature of the animals, a certain number of experimental animals are cautious by nature, and they are hesitant and unwilling to move forward in front of the wooden piece, which leads to low experimental efficiency. Utility Model Content
[0004] The purpose of the utility model is to overcome the defects in the prior art and provide a limb recovery evaluation device for medical experimental animals, which allows the experimental subjects to pass through various test units through a designed test channel to avoid running away or falling during the process, and drives the experimental subjects to quickly pass through the test units through a driving component to improve the experimental efficiency.
[0005] The purpose of the utility model is achieved as follows: A medical experimental animal limb recovery assessment device comprises a box body, the box body is formed by a bottom plate and a side wall, a first plate body assembly, a second plate body assembly and a third plate body assembly are sequentially arranged in the box body from top to bottom, an inlet and an outlet are arranged on one side of the box body along the length direction, the inlet is arranged at the upper part of the box body, and the outlet is arranged at the lower part of the box body; the first plate body assembly comprises a first plate body fixedly arranged on the side wall of the box body, the first plate body extends to the other side of the box body along the length direction of the box body and is connected to a first step, a first driving assembly is arranged on one side above the first plate body near the inlet, a first attractant is arranged on the first plate body at one end connected to the first step, a first fault area is also arranged on the first plate body, and a first test unit is arranged in the first fault area.
[0006] When the utility model is working, a circuitous test passage from the entrance, the first plate body, the second plate body, the bottom plate to the exit is formed in the box body, and the test device is of a closed structure. The test subject can only pass through each test unit through the designed circuitous test passage, and will not escape in the middle of the test and cause the loss of the test subject; the elastic pad arranged under the test unit can prevent the test subject from falling and getting injured in the narrow passage of the test unit, and provide sufficient buffer to protect the safety of the test subject; the driving components and the attracting parts are arranged on both sides of the test unit, which can further guide the cautious nature, hesitant and unwilling to move forward in front of the narrow passage.

The forelimbs of the experimental subjects cannot use the suspended side of the elastic pad to climb to the higher side of the upper plate. The experimental subjects who fall down without completing the test unit of the upper layer cannot move the foraging attractant in the reverse direction.

[0010] Third, through holes for placement are provided on the plates above the second and third lures, respectively, to facilitate operators in placing the lures into designated areas, thereby further improving the efficiency of guiding the experimental subjects forward; the second through hole and the third through hole are connected by a vertical pipe, which can prevent the third lure from falling onto the second plate due to operational errors when being placed, thereby reducing the placement difficulty for operators.

The experimenter only needs to observe the residue of the attractant in the device after a preset time to know the test result, and no real-time observation and recording are required, which reduces the operational requirements of the test experiment.
[0042] The limb balance test method for medical experimental animals of the utility model is specifically as follows. According to the test units with gradually increasing difficulty designed by the limb recovery evaluation device for medical experimental animals, the experimental mice may have the following situations:
[0043] like Figure 5As shown: the No. 1 experimental mouse passes through the first test unit 22, the second test unit 32 and the third test unit 42 in sequence according to the designed dotted lines, and does not fall during the whole process. Therefore, the first lure 23, the second lure 33 and the third lure 43 prepared along the way can be eaten up. After the second sensor 14 on the side of the exit 13 sends a signal, the operator observes that all the lures are eaten up, and it can be determined that the No. 1 experimental mouse has passed all the test units, and the integration and coordination evaluation of the limb motor function is recorded as excellent;
[0044] like Figure 6 As shown: the No. 2 experimental mouse passes through the first test unit 22, the second test unit 32 and the third test unit 42 in sequence according to the designed dotted lines, but fails to pass the first test unit 22 and directly falls to the second plate 3 and continues to move forward. Therefore, the first lure 23 prepared along the way cannot be eaten, while the second lure 33 and the third lure 43 are all eaten. After the second sensor 14 on the side of the exit 13 sends a signal, the operator observes the eating of the lure, and can judge that the No. 2 experimental mouse only passes the second test unit 32 and the third test unit 42, and the evaluation record of the integration and coordination of the limbs motor function is good;
[0045] like Figure 7 As shown: the experimental mouse No. 3 passes through the first test unit 22, the second test unit 32 and the third test unit 42 in sequence according to the designed dotted lines, but fails to pass through the first test unit 22 and the second test unit 32 and directly falls to the third plate 4 and continues to move forward. Therefore, the first lure 23 and the second lure 33 prepared along the way cannot be eaten, and the third lure 43 is eaten. After the second sensor 14 on the side of the exit 13 sends a signal, the operator observes the eating of the lure, and can judge that the experimental mouse No. 3 only passes through the third test unit 42, and the integration and coordination evaluation of the limb motor function is recorded as medium;
[0046] like Figure 8 As shown, the experimental mouse No. 4 passes through the first test unit 22, the second test unit 32 and the third test unit 42 in sequence according to the designed dotted lines, fails in the first test unit 22, the second test unit 32 and the third test unit 42 and directly falls to the bottom plate 5 and continues to move forward. Therefore, the first lure 23, the second lure 33 and the third lure 43 prepared along the way cannot be eaten. After the second sensor 14 on the side of the exit 13 sends a signal, the operator observes the consumption of the lure and determines that the experimental mouse No. 4 has failed all the test units, and the evaluation of the integration and coordination of the limb motor function is recorded as poor.
[0047] According to the experimental requirements of medical research, pharmacological research, disease research, rehabilitation research or other medical research, the medical experimental animal limb recovery assessment device provided in this embodiment can be used for small and medium-sized terrestrial experimental animals including but not limited to: white mice, nude mice, black mice, rabbits, cats, dogs, etc.; researchers can also adjust the width and shape of each layer of test units according to the experimental design requirements, replace the driving components that the experimental subjects are afraid of and the attractants that they like, and set more layers of plates to achieve a more accurate division of the limb balance index parameters of the experimental animals, which is not limited here.
[0048] The present utility model is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed in the present utility model, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present utility model.
