Technical Field
The utility model belongs to the technical field of an animal experiment, in particular to suction-type developments toxicant exposure device.
Background
More toxic gas can be generated in the livestock and poultry house, which can affect the health of animals and bring more and more diseases to the animals. At present, no method is available for effectively controlling the toxic substances in the animal husbandry, and the harm to animals caused by the toxic substances is not clearly understood in many farms, so that research on the influence of the gaseous toxic substances on the health of the animals is urgently needed.
The dynamic contamination experiment is generally carried out in a contamination cabinet, and the contamination cabinet can be divided into a movable contamination cabinet and a static contamination cabinet according to whether air in the contamination cabinet exchanges with the outside in the contamination process; the movable toxicant exposure cabinet has many advantages because the external air is continuously supplemented in the toxicant exposure process, mainly can keep the concentration of toxicant exposure substances unchanged, and ensures that the partial pressure of carbon dioxide in the toxicant exposure cabinet is constant and the temperature and humidity are constant; in the static toxicant exposure cabinet, air in the cabinet is isolated from the outside in the toxicant exposure process, and as the toxicant exposure time goes on, the animals continuously inhale oxygen and exhale carbon dioxide, the oxygen concentration in the cabinet continuously decreases, and the carbon dioxide concentration continuously increases. Meanwhile, the body temperature of the animals is higher than the ambient temperature, so that the temperature in the cabinet can be increased along with the body temperature in the toxicant exposure process, and the humidity in the cabinet can be gradually changed under the influence of the respiration of the animals. It follows that in most tests dynamic contamination has become a trend to replace static contamination, except for a few special requirements.
At present, the dynamic inhalation contamination technology in China is developed rapidly, great progress is made in the aspect of automatic control, but the stable mature stage is not achieved, and particularly further improvement is needed in the aspects of atomized particle size, waste gas and waste water discharge, airflow pressure change, interaction relation between the airflow pressure change and a laboratory and the like.
