Box-type negative pressure experimental dog fixing and protecting device

Abstract

The invention provides a box-type negative-pressure experimental dog fixing and protecting device. The device comprises a lower box body with brake casters; the lower box body is connected with a movable box cover through a chain to compose a movable negative pressure box body. After an experimental dog is placed in the lower box body, the body of the experimental dog is jacked by a jacking deviceto be left-and-right immovable; when the movable box cover is put down, a neck upper concave hole in the movable box cover and a neck lower concave hole in the lower box body clamp the neck of the experimental dog to be immovable; meanwhile, a pressing device in the movable box cover presses the back of the experimental dog to be up-and-down, immovable and a collecting device of the lower box body collects and cleans excrement excreted by the experimental dog; and a front wall grid and a rear wall grid of the lower box body, an upper cover grid of the movable box cover and a negative pressurefan form directional negative pressure airflow in the negative pressure box body, so that the body of the experimental dog is prevented from being hurt by air temperature or air pollution and an experiment can be carried out smoothly. The device has the beneficial effects that the device for conveniently, quickly and safely fixing and protecting experimental dogs in scientific research experiments is developed, and existing problems in the aspect are solved.

Description

technical field [0001] The invention relates to a box-type negative pressure experiment dog fixing protection device. Background technique [0002] In recent years, the use of animals, especially medium-sized dogs, to conduct simulated scientific experiments to study the impact of drugs or air pollutants on humans has been vigorously developed. At present, the experimental dogs used for simulation experiments are generally fixed with cloth bags. There is no good fixation method for wrapping around or tying with ropes. The experimental dog cannot be completely fixed with a cloth bag. Tight binding will affect the breathing and normal physiological limits of the experimental dog. If the binding is not tight, it will cause midway escape. During the experiment, because the limbs of the experimental animals cannot be fixed firmly, turning over and twisting the neck back and forth will also affect the experimental process and experimental results, and the feces of the experimental...

Problems solved by technology

[0005] The beneficial effects of the present invention are: in the scientific research experiment, it is convenient, quick and safe to complete the fixation and protection device of the experimental dog, and the directional flow of negative pressure and directional airflow ensures that the body of the experimental dog will not be polluted by air temperature or gas during the experiment The damage caused, solves the problem that exists in this area
