Abstract

The invention discloses an improved static inhalation toxicant exposure cabinet and belongs to the technical field of toxicant exposure cabinets, the improved static inhalation toxicant exposure cabinet comprises a cabinet body and a heater and a fan which are arranged in the cabinet body, the cabinet body is a cylindrical container, a sample volatilization box is arranged at the bottom end of a cover plate of the cabinet body, the sample volatilization box is a tetrahedron, an evaporation pan is arranged at the bottom end of the sample volatilization box, the heater is arranged at the bottom end of the evaporation pan, one end of the sample volatilization box is provided with a fan, the other end of the sample volatilization box is provided with an inclined guide plate, and an air outlet is formed close to the bottom end of the guide plate. By using the improved static inhalation toxicant exposure cabinet, the concentration uniformity of tested chemicals in the cabinet body can be effectively improved, the test time is shortened, the electric energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of poisoning cabinets, in particular to an improved static inhalation poisoning cabinet. Background technique [0002] There are mainly two ways to establish animal models of inhalation exposure, one is static inhalation exposure, and the other is dynamic inhalation exposure. Static inhalation exposure is to place experimental animals in a closed container with a certain volume, add a certain amount of volatile liquid test chemical or a certain volume of gaseous test chemical, and form a substance containing the required amount in the closed container. The air environment at the concentration of the test chemical infects the animals. Dynamic inhalation exposure is to place experimental animals in an air-flowing poisoning cabinet. The poisoning cabinet is equipped with a power system for replenishing fresh air and discharging the mixed gas of the test chemical and a formula for quantitatively replenishing th...
