Device for testing activity of animals under tail suspension state

Abstract

The invention discloses a device for testing activity of animals under the tail suspension state. The device comprises an uncovered testing box body, a sealed collecting and transmitting box and a computer operation system which are connected in turn, wherein the inner part of the testing box body is divided into eight testing lattices capable of partitioning small animals by partition plates; a beam is arranged above the testing box body by a supporting rod which is fixed on the testing box body; eight sensors are fixed on both sides of the beam by sensor fixing rods and correspond to the positions of the testing lattices below; and a plurality of hooks are connected below the sensors. The device provided by the invention for testing activity of the animals under the tail suspension state is reasonable in design and compact in structure, and meets the needs of each animal suspension test.

Description

technical field [0001] The invention relates to animal experiment equipment, in particular to a device for testing animal activities in a tail-suspension state, which is applied to animal suspension experiments. Background technique [0002] The animal tail suspension test refers to monitoring, recording and analyzing the immobility time and struggling intensity of animals within a specified period of time. It is a common experimental method to judge the desperate state of animal behavior. It has important application value in drug efficacy evaluation. [0003] At present, there are usually three experimental techniques for monitoring tail suspension activities of animals at home and abroad. One is video tracking technology, which uses video to obtain information such as the immobility time of animals in the state of tail suspension. Although this technology provides a more intuitive display interface, its tracking error cannot be ignored, especially when the number of exp...

AI Technical Summary

Problems solved by technology

Although this technology provides a more intuitive display interface, its tracking error cannot be ignored, especially when the number of experimental animals increases to more than 2, the inaccuracy of video tracking is more prominent

The second is the infrared pyroelectric principle, which is easily affected by the external environment temperature and animal movement state. When the external environment temperature is too low or the animal movement is slow, misjudgment often occurs, resulting in inaccurate results
