Multichannel testing device for vertical rotation persistence of mice

Abstract

The invention discloses a multichannel testing device for vertical rotation persistence of mice. The multichannel testing device comprises a support, wherein a plurality of rotating devices for driving a plurality of mice to rotate separately are arranged on the support; the upper parts of the rotating devices are separately connected with the corresponding driving devices; a plurality of receiving containers for receiving the mice falling from the rotating devices are separately arranged under the corresponding rotating devices; the multichannel testing device further comprises a speed measuring device for measuring the rotating speeds of the rotating devices and a timing device for measuring rotating time of the mice; the driving devices, the speed measuring device and the timing device are all connected with a controller. According to the multichannel testing device disclosed by the invention, multiple arms and a tail of each mouse wind an inverted T-shaped grabbing and winding part, and do vertical rotation along with a main rotating shaft by taking the head and the tail of the mouse as an axis; an anti-fatigue anti-vertigo experiment is carried out according to the posture; compared with traditional several experimental modes, the multichannel testing device disclosed by the invention has the advantages that the persistence can be changed along with the rotating speed, and corresponding experimental contents are more abundant; in addition, the multichannel testing device is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to a multi-channel test device for vertical rotation endurance of mice. Background technique [0002] Experimental mice wrap their four paws and tail around a thin rod that rotates in the axial direction, and are driven by the thin rod and the mesh bar at the end of the rod to perform vertical rotation at a constant or variable speed with the head and tail as the axis. Observing the persistence of passive rotation of mice under the rotating speed, this experiment can be considered as belonging to the anti-fatigue or anti-vertigo experiment of mice (see Ge Erning, Yuan Yong, Ying Huazhong, etc. Development of Data Memory Animal Fatigue Tester[J] .Chinese Journal of Comparative Medicine, 2006, 16(8): 489-490 and Hui Enjian, Ge Erning, Sheng Zhenhua, etc. Development of a self-recording 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 deve...

[0003] Adopting this method to test the anti-fatigue and anti-vertigo ability of animals has not been reported at home and abroad. Similar animal anti-fatigue and anti-vertigo experiments currently use standing wires and standing poles in the industry (see Ge Erning, Yuan Yong, Ying Huazhong, etc. .Development of data memory animal fatigue tester[J]. Chinese Journal of Comparative Medicine, 2006, 16(8): 489-490), hanging bar type (see Hui Enjian, Ge Erning, Sheng Zhenhua, etc. Self-recording animal hanging Development of bar durability testing device [J]. Chinese Journal of Comparative Medicine, 2014, 24(7): 77-80), flipping and other methods, the market lacks the use of mice along the rotating rod to carry out head and tail as the axis. Vertical rotation movement, an experimental device for observing the persistence of mouse grasping and entanglement at different rotational speeds
