Description

Technical Field

[0001] The utility model relates to the technical field related to animal experimental equipment, in particular to a measuring device for a rat and mouse inclined board test. Background Art

[0002] Basic research on spinal cord injury repair is one of the key points and difficulties of basic research. In animal experiments, especially in spinal cord injury repair research using rodents as models, the evaluation of injury repair is often multi-faceted. Among them, behavioral evaluation is indispensable, but most of the current behavioral evaluation instruments for spinal cord injury are expensive or difficult to move, and are often difficult to obtain. The inclined board test has a simple experimental device and does not require the cooperation of animals to complete related experiments. It is very important in the evaluation of spinal cord injury and is a more scientific method to evaluate the recovery of motor function after injury.

[0003] At present, the inclined board test devices used in the experiment are mostly simple and homemade, and there is a lack of related experimental devices for sale on the market. The current homemade inclined board test device is usually a simple two-board device, which requires two people to operate the experiment. The angle between the two wooden boards is manually adjusted and supported for a period of time to complete the experiment. Although the device is simple, it is very inconvenient when conducting large-scale animal experiments, which consumes a lot of energy of the experimenters, and the error is large, and it cannot control the slight change of the angle. In this simple experimental device, the failure rate of the experiment is high, and repeated experiments can easily cause animal fatigue, waste time and energy, and cause large experimental errors. Experimental animals are prone to change their posture on the wooden board and lie sideways, or grab the edge of the board or any other possible gap driven by instinct, causing the experiment to fail.

[0004] The Chinese patent with application number 201920906503.3 discloses a measuring device for the rat inclined board test, but the device requires manual reading, has large errors and low precision. It is inconvenient to control the angle, and it is not convenient to adjust the angle back and forth. The device cannot be paused at any time. In the inclined board test, the animal is required to be placed on the inclined board for 5S without sliding more than three times to be considered successful at this angle. When adjusting the next angle for testing, the animal needs to be taken off the inclined board and the angle is adjusted before the animal is placed on the inclined board for the experiment. Obviously, the device cannot control the pause at any time to adjust the angle and complete the inclined board test correctly and scientifically. Although the front section has an anti-slip area, it is easy for the animal to climb to the junction and grab the edge, causing the experiment to fail. The gears of the stepper motor and the gears of the track have high requirements for matching, and they are easily damaged after long-term use. Utility Model Content

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example: Figure 1 , Figure 2 , Figure 3 As shown, the utility model is a rat and mouse inclined board test measuring device, comprising a base 1, one end of the base 1 is connected to a rotating plate 3 via a parent-child hinge 2, and the other end of the base 1 is fixed with an angle measuring ruler 4 with a quarter arc and used to measure the rotation angle of the rotating plate 3, and an electric push rod 5 is provided between the base 1 and the rotating plate 3 to drive the rotating plate 3 to rotate, and straight plates 10 are provided on both sides of the rotating plate 3, and a U-shaped structure is formed between the two straight plates 10 and the rotating plate 3, and an inclinometer 6 for measuring the inclination of the rotating plate 3 is installed at the free end of the rotating plate 3, and the inclinometer 6 is installed with a red laser emitter 7 for indicating the scale on the angle measuring ruler 4. A power transformer for powering the electric push rod is provided on the base 1, and the power transformer controls the forward and reverse rotation of the DC power supply by remote control to control the extension and retraction of the electric push rod. The whole experiment can be operated by one person, and the angle between the base 1 and the rotating plate 3 can be controlled by remote control; the value can be accurately read with a precision of 1 decimal place in a digital display mode, and the scientific nature of the data can be ensured by double checking. The surface of the rotating plate 3 is provided with a rubber pad 8. The U-shaped plate constructed by the rotating plate and the straight plate and the fully laid rubber pads at the bottom can prevent animals from grabbing the edge and causing the experiment to fail, thereby increasing the success rate of the experiment. The bottom of the rotating plate derives a 4*4cm special-shaped protrusion forward, which is convenient for placing the inclination angle measuring instrument and the laser transmitter.

[0022] The base 1 is 20cm wide and 50cm long. The rotating plate is preferably made of wood and has a certain weight for counterweight. The size is 60*20*1cm in length, width and height. A U-shaped clip is provided at the open end of the base. The U-shaped clip is a hand-tightening type that can fix 1 / 4 circle. When not in use, it is convenient to loosen it and remove the 1 / 4 circle for easy storage. The opening size of the U-shaped clip is 4CM. The height of the straight board 10 is 15cm.

[0023] A limiter is provided between the base 1 and the rotating plate 3 to limit the closing angle between the base 1 and the rotating plate 3, so as to prevent the push rod from being damaged due to the closing angle of the two plates being too small.

[0024] The electric push rod in the utility model is controlled by a 24V DC power supply, and the forward and reverse directions of the DC power supply are controlled by a remote controller to control the extension and retraction of the push rod. The power cord connecting the push rod is fixed to the base to prevent accidental pulling and damage.

[0025] The bottom of the structure of the quarter arc angle measuring ruler 4 has a bending structure, which is bent by 90 degrees to facilitate the U-shaped clamp to be fixed on the base rotating plate. The radius of the circle is 54cm, and there are corresponding angle scales on the circle. The material is steel structure, and the corresponding scales are laser-marked.

[0026] When working, this kind of rat and mouse inclined board test measuring device connects a rectangular bottom plate and a U-shaped rotating plate through a parent-child hinge. The rectangular bottom plate is the base, the U-shaped plate is the rotating structure, and the upper surface of the U-shaped rotating plate is paved with a rubber pad, and both sides are smooth. A 1 / 4 circle angle measuring ruler 4 is fixed on the base, and there is an inclinometer that digitally displays the angle on the rotating plate. During the experiment, the remote control is used to extend the electric push rod forward, and the numerical changes on the inclinometer are observed. After reaching the appropriate angle, the animal is placed on the rubber pad of the U-shaped structure and kept still for five seconds. Three consecutive successes indicate that the animal can support the angle. Remove the animal from the U-shaped plate, and then remotely control the electric push rod to continue to increase the angle between the rotating plate and the straight plate. Stop after adjusting to the appropriate angle, and then place the animal on the rotating plate of the angle again. If the animal cannot catch and slide down, it proves that the animal cannot support at this angle, and record the data. After the experiment, the remote control is used to control the electric push rod to retract. The angle that the animal can finally support is read out by double checking with a digital inclinometer and an angle measuring ruler 4. The lower end of the inclinometer is provided with a laser, which shines on the compass for easy reading.
