example 1

[0018] like figure 1 , figure 2 As shown, the rotarod instrument includes a RAT box 1, and a transmission chamber 2 is provided at the left end of the RAT box 1. The transmission chamber 2 is equipped with 57 stepping motors 3, and the stepping motors 3 pass through the PE board motor frame connected up and down. 4 and the steel plate motor frame 5 are fixed on the bottom of the transmission chamber 2, and the 57 stepping motor 3 is inlaid with the motor outer shaft 6. The right side of the transmission chamber 2 is a test box 7, in which several test chambers are separated by a plurality of partitions 8 arranged vertically and uniformly, and the test rotating shaft 9 passes through the shaft hole on the partition 8 and passes through the box of the test box 7 transversely. Body, its two ends are respectively fixed on the two ends of test case 7 by bearing 10 and bearing frame 18. The right end of the motor outer shaft 6 in the transmission chamber 2 and the left end of the...

Abstract

The invention discloses an automatically-analysing rod-rotating instrument controlled by computer program, comprising an RAT box, wherein a transmission chamber and a test box are arranged in the box, a test rotary shaft penetrates all test chambers in the test box, and the both ends of the test rotary shaft are fixed at the both sides of the test box via bearings respectively. Spring clips are installed between the outer shaft of a motor and the test rotary shaft respectively, and the both ends of each of silencing springs are fixed on the two spring clips. A movable baffle, an arc fixed plate and a sanitary cushion plate are installed in each test chamber, and the rod-rotating instrument is further provided with an automatic recording and analysing system. The rod-rotating instrument disclosed by the invention has the following advantage that the noise of the motor is furthest decreased by the double springs, thus improving experiment accuracy. A rested rat can be effectively prevented from jumping out of the instrument to be hurt due to the arrangement of the baffle and the arc fixed plate. Guarantee for cleanness in the test chambers can be promoted via the movably-arranged sanitary cushion plate. The recording and analysing system can flexibly set experiment time, rotational speed and rotational mode, so that data processing is more accurate and rapid.

Description

technical field [0001] The invention relates to a computer program-controlled automatic analysis rotarod instrument, which is suitable for testing the influence of drugs on the movement coordination and anti-fatigue characteristics of experimental animals mice and rats, so as to meet the screening requirements of related drugs. Background technique [0002] At present, there are still many defects in the known experimental animal rotarod apparatus. Firstly, the noise generated by the instrument during operation is very large, which greatly interferes with the experimental animals and affects the test results. The second is that the experimental mice sometimes jump out of the rotarod instrument during the experiment, which causes inconvenience in operation or falls of the experimental mice, and makes the experimental results inaccurate. The third is that the excrement of experimental animals is inconvenient to clean. Fourth, the values ​​recorded by most rotarod instruments ...
