[0002] Experimental mice do unsupported passive rotation on a rotating platform, and observe the persistence of passive rotation of mice at different rotational speeds. This experiment can be considered to belong to the anti-fatigue or anti-vertigo experiment of mice (see Gurning, Yuan Yong, Ying Huazhong, etc. Development of data memory animal fatigue tester [J]. Chinese Journal of Comparative Medicine, 2006, 16(8): 489-490. He Hui Enjian, Ge Erning, Sheng Zhenhua, etc. Self-recording Development of animal hanging bar durability test device [J]. Chinese Journal of Comparative Medicine, 2014, 24(7): 77-80.), which can be used in the research and development of anti-fatigue drugs, anti-vertigo drugs, antidepressant drugs, and stimulant drugs. In the experimental research related to medicine and aerospace, but there is no such device on the market that can automatically record

An automatic recording and variable-speed rotating platform experimental device, the bottom end of the main shaft is located in the funnel, and the bottom end is connected with a driving device, and the driving device is connected to the controller; the top of the main shaft is fixed with a ball crown for mice to grasp Jumping platform; the main rotating shaft is also provided with a speed measuring device for detecting the rotational speed of the main rotating shaft; the speed measuring device includes a speed measuring turntable coaxially fixed on the main rotating shaft, and a speed measuring magnetic block is fixed on the speed measuring turntable. Hall sensor on one side, the Hall sensor and the speed-measuring magnetic block are opposed up and down and cooperate with each other, and the distance between the Hall sensor and the main rotating shaft is equal to the distance between the speed-measuring magnetic block and the main rotating shaft; the Hall sensor is connected with the controller. The small mouth of the funnel is provided with a monitoring device for detecting whether the mouse has fallen; the monitoring device includes several pairs of infrared radiation sensors arranged on the inner wall of the funnel, and each pair of infrared radiation sensors is connected to the controller; Has a timer.
Description
Technical field [0001] The present invention relates to an automatic recording variable speed rotational jumping table experimental apparatus. Background [0002] Experimental mice do unsupported passive rotational movements on a rotating platform, and observe the durability of passive rotation of mice at different rotational speeds, which can be considered to belong to mouse anti-fatigue or anti-vertigo experiments (see Gelning, Yuan Yong, Ying Huazhong, et al. Development of data memory animal fatigue tester[J].Chinese Journal of Comparative Medicine,2006,16(8):489-490.HeEnjian, Ge Erning, Sheng Zhenhua, et al.Development of self-recording animal hanging bar durability test device[J].Chinese Journal of Comparative Medicine, 2014,24(7):77-80.), which can be used for the development of anti-fatigue drugs, anti-vertigo drugs, antidepressants, stimulants and medical, aerospace-related experimental research. However, there is a lack of such devices on the market that can automatical...
