Normal pressure gas experiment animal cabin

Abstract

The invention discloses a normal pressure gas experiment animal cabin comprising an outer cabin, an animal cage, an air supply system and an environment control system, wherein sliding rails are arranged on the bottom of the inner side of the outer cabin, and a ring baffle is arranged on the longitudinal section in the middle portion of the left-and-right direction of the outer cabin along the periphery of the cabin inner wall. Pulley wheels are arranged on the bottom of the animal cage, and pull rods are arranged on side wall plates of the animal cage, and the pulley wheels and the pull rods are used for pulling the animal cage to move on the sliding rails. A cage body of the animal cage penetrates through the ring baffle, the air supply system is arranged on the outer side of the outer cabin and is used for providing air for the outer cabin, and the environment control system is arranged on the outer side of the cabin and is used for absorbing and clearing harmful gas in the cabin and transmitting filtered gas back to the cabin. The normal pressure gas experiment animal cabin is reasonable and scientific in design, the need that experiment animals are exposed for a long time in a specific gas environment at normal pressure condition is satisfied, and scientificalness and objectivity of related experiments and research are ensured.

Description

technical field [0001] The invention relates to an animal experiment device, in particular to a normal-pressure gas experiment animal cabin. Background technique [0002] Oxygen is an essential substance for aerobic organisms to maintain life. Changes in the oxygen content in breathing air will have a significant impact on the body. In the plateau environment, hypoxia can cause a series of pathophysiological reactions in the body; during high-pressure exposure in diving, the oxygen content in the breathing gas is usually higher than that in normal pressure air. have a special impact. Most clinical diseases (such as stroke, myocardial infarction, thrombosis, trauma, lung disease, blood system disease, diabetic vascular complications, etc.) have the pathophysiological basis of ischemia and hypoxia. In addition, oxygen is also widely used in the treatment of various clinical diseases and wounds. In addition to producing therapeutic effects, improper use can also cause damage....

AI Technical Summary

Problems solved by technology

First, open the cabin regularly every day to clean the cabin, the animals are exposed to the air, the special oxygen concentration environment changes, and the experimental conditions also change, resulting in unstable or substandard models.

Second, during the continuous exposure process of two regular openings and cleanings, the harmful gases emitted by the animal excrement will accumulate in the cabin to a certain extent, causing adverse effects on the animals

Third, some cabins reduce the carbon dioxide produced by animal metabolism by laying carbon dioxide absorbents on the bottom of the cabin, but due to the long exposure time of animals and the high humidity in the cabin, the absorption effect is limited

Fourth, some cabins maintain the environment in the cabin by increasing the ventilation, but this will consume a large amount of gas (pure oxygen, nitrogen or a mixed gas containing a specific oxygen concentration), and the large gas flow will also cause the temperature in the cabin to increase. too low

[0004] There are also domestic researchers who have designed special devices to conduct hypoxic research, but these special devices are designed for hypoxic exposure, and none of them can achieve effective exposure microenvironment control, and cannot carry out long-term continuous exposure
