Animal fixation box

Abstract

The invention discloses an animal fixation box. The animal fixation box comprises a rectangular frame which is formed by a front wall, two side walls (1) and a rear wall (2) in an enclosing mode and provided with an upper opening and a lower opening; a box bottom (3) is arranged at the lower opening of the rectangular frame, and a box cover (4) is arranged at the upper opening in a covering mode; the front wall is divided into an upper front wall (51) and a lower front wall (52), the upper edge of the lower front wall (52) and the lower edge of the upper front wall (51) are each provided with a semicircular notch, and the two semicircular notches can be matched with each other and locked through lock catches (8) to form a hole (6) used for fixing an animal to be fixed; the diameter of the hole (6) is larger than that of the neck of the animal to be fixed and smaller than that of the head of the animal to be fixed; one end of the box cover (4) is hinged to the top end of the rear wall (2), and the other end of the box cover (4) is connected with the upper edge of the upper front wall (51). The animal fixation box is wide in application range, fixation operation is easy and convenient, and the animal can be carried and moved with the animal fixation box conveniently.

Description

technical field [0001] The invention relates to animal experiment equipment, in particular, to an animal restraint box. Background technique [0002] Most of the studies on brain function activities (such as brain electrical activity, single nerve cell discharge activity, brain function imaging, etc.) of animals (such as cats, rats, and mice) under normal physiological activities and awake states are carried out under anesthesia Yes, the data obtained in this way may not fully reflect the brain function activities under normal physiological conditions, and different anesthetics themselves have more or less effects on brain function activities. Therefore, it is of great significance to directly study the brain function activities of animals in normal physiological state and awake state to reveal the rules and mechanisms of brain function activities. However, to realize this research technique, it is necessary to restrict the large-scale movement of the animal's body, and it ...

Problems solved by technology

[0003] At present, the experimenters have designed some methods (such as monkey chair: Monkey chair) to restrict the movement of animals during the experiment, but these methods have many weaknesses: 1) The monkey chair (sitting and standing) is only suitable for the physical constraints of monkeys , not suitable for the limitations of other animals (such as cats, rats and mice); 2) The horizontal and vertical conversion connections of the head fixing bracket are complex and cumbersome, and the stability is poor, and it takes a lot of time to install and disassemble the bracket during the experiment; 3) The monkey chair is separated from the head fixing bracket. The fixing bracket is generally fixed on the research workbench, which cannot be moved, and the flexibility is very poor. It is not possible to conduct different tests on the same individual animal.
