Problems solved by technology

[0005] Aiming at the problems that the current standing animal anti-fatigue test device takes a long time and the results are prone to errors, the invention proposes a hanging bar that can automatically record the number of times the mouse catches the bar and the duration of the bar hanging, and is time-consuming and accurate and reliable.

Embodiment 2

[0036] Embodiment 2 The difference between this embodiment and Embodiment 1 is that the water pool is composed of a water tank and a water reservoir. Small animals with a weight of 15g enter and exit, and there are 3 inlet and outlet holes at the lower end. When the water level in the tank is full beyond the third vertical partition, it will be discharged into the reservoir from the overflow outlet. The function of the first vertical partition is to act as an electric When the water valve is opened and the water level of the tank drops, keep the water level in the tank not lower than the height of the first vertical partition (the water outlet speed of the water outlet is much higher than the water inlet speed), and the second vertical partition can isolate the experimental animals from the water inlet and outlet; The volume of the pool is twice the size of the sink, with a built-in adjustable temperature controller and submersible pump; the submersible pump injects the constan...

Embodiment 3

[0037] Example 3 Take 30 experimental healthy mice, weighing 15-25 g, and divide them into two groups, 15 mice in one group are fed normally, and 15 mice in the other group are fasted for 1 day and only fed with water. Adjust the temperature of the thermostat to 22°C, preheat for half an hour, turn on the switch of the controller when the temperature of the pool water rises to about 22°C, and turn on the submersible pump, so that the water level in the tank rises slowly to the C position of the partition, put the mouse in, cover the top Cover, the instrument will automatically record the number of times the mouse grabs the bar and the corresponding time. The experimental time of a mouse can be determined according to the mouse's physical fitness and whether it is willing to grab the bar multiple times. A robust mouse will have Grab the bar 5-10 times, if the physical strength is not more than 5 times, they are no longer willing to grab the bar. Figure 5 You can see the result...

Abstract

An animal grab duration test set comprises a water tank, a sensor, a controller with a control panel, and a controller power source. The water tank comprises a water basin and a storage tank right below the water basin. A top cover plate of the water basin is provided with an entry used for placing in an animal to be tested. A submersible pump and a thermostat are disposed in the storage tank. The bottom of the water basin is provided with a water inlet and a water outlet communicated with the storage tank; the water outlet is provided with an electric water valve. The sensor comprises a spring, a diaphragm, a horizontal bar and an optical coupler. The controller is in signal connection with both the sensor and the electric water valve. The control panel of the controller is provided with a controller power switch, a query button, a clear button and a display. The controller power switch is connected with a power control module of the controller. The animal grab duration test set has the advantages that the number of times and duration of a mouse grabbing the bar in the experimental environment are automatically recorded, the test set is simple, measurement results are accurate and duration of each measurement is short.

Description

technical field [0001] The invention relates to a device for testing the durability of hanging bars for animals. Background technique [0002] Animal claw-hanging bar durability test is also a static anti-fatigue test, which can be used in the development of anti-fatigue drugs, antidepressant drugs, stimulant drugs and related medical research. When mice swim in a closed pool, due to fear or If the physical strength is exhausted, they will often look for a support point that can be grasped, and when the four claws and arms cannot support the entire body weight, they will give up grabbing the bar and fall into the water. Repeat this many times, and finally give up grabbing the bar. The hanging time and frequency can be used to evaluate the drug efficacy and related medical effects of the developed drugs. [0003] This experimental method of allowing animals to naturally grab the bar and hang the arm can be used for the detection of animal static fatigue, and can be used for ...
