Active moving type animal experiment platform

Abstract

The invention relates to an active moving type animal experiment platform. The active moving type animal experiment platform comprises a base, a fixing piece for fixing a certain part of an animal, and a fixing arm, wherein the base comprises a supporting platform, a site placing platform and a driving system; the site placing platform is horizontally connected on the supporting platform in a sliding manner; an outer ring is arranged on the fixing arm; an inner ring is in spherical hinging to the inner part of the outer ring; the fixing piece is arranged on the inner ring; pressure sensors aredistributed on the outer ring in a spacing manner; a first trigger arm which corresponds to and is abutted against the detection end of each pressure sensor is arranged on the inner ring; and when the animal moves, the pressure sensors are triggered, so that the driving system drives the site placing platform to move in the direction opposite to the moving direction of the animal. According to the active moving type animal experiment platform disclosed by the invention, in experiment, when the animal has the desire of horizontal moving, a signal is transmitted by a corresponding pressure sensor to the driving system to drive the site placing platform to move in the opposite direction, so that the moving requirements of the animal are met; and in the period, the animal does not need to consume the physical strength to drive the whole placing platform to move, the physical strength consumption of the animal is small, the application range is wide and the applicability is good.

Description

technical field [0001] The invention relates to the technical field of animal experiments, in particular to an active movement type animal experiment platform. Background technique [0002] In biological experiments, there is a type of behavioral experiment. This experiment is to put animals in a field environment to observe the behavior of animals. The common ones are three-box social experiment of mice and open field experiment of mice. Sometimes in order to study some neuroscience and other related issues, it is necessary to fix a certain part of the experimental animal for observation and manipulation of the experimental animal, such as using a large two-photon microscope to observe and record the mouse brain in vivo. However, after the experimental animals are fixed, the experimental animals cannot move freely in the field, which is a contradiction. [0003] Most of the existing head fixation techniques and devices that ensure relatively free movement of experimental a...

Problems solved by technology

[0004] However, all of the above are based on the mouse’s own power as the power source, and the external experimental equipment of the experiment is driven. The physical energy consumption of the experimental animals is relatively large, and some special-shaped objects need to be added as part of the experiment in some experiments, such as three boxes. Social experiments, the above experiments are difficult to add other real items on the field, resulting in a limited scope of use, which needs further improvement
