Animal experiment anesthesia toxic gas utilization treatment and purification device

Abstract

The invention discloses an animal experiment anesthesia toxic gas utilization treatment and purification device. The device comprises an animal anesthesia chamber with an animal throwing opening in the top. A diethyl ether concentration measuring instrument and a horizontal metal grid net used for bearing animals are installed in the animal anesthesia chamber. A diethyl ether volatilization chamber is arranged below the metal grid net in the animal anesthesia chamber; a diethyl ether dispenser is arranged outside the animal anesthesia chamber; the diethyl ether dispenser is communicated with the diethyl ether volatilization chamber through an ascending pipe with a diethyl ether inlet control valve; the diethyl ether volatilization chamber is further communicated with an air inlet pipelinewith an air inlet control valve, a plurality of diethyl ether exhaust ports are formed in the animal anesthesia chamber and located above the metal grid mesh, the diethyl ether exhaust ports are connected to a gas collecting pipe through pipelines with diethyl ether outlet control valves, the gas collecting pipe is communicated with a purification treatment tank, and a draught fan is arranged on the communicating pipeline. The system device can ensure that diethyl ether gas can be fully utilized in the whole process and cannot be diffused to the external environment, and the problems in animalanesthesia teaching experiments at present are thoroughly solved.

Description

technical field [0001] The invention belongs to the technical field of medical experiments, in particular to a device for utilizing, treating and purifying anesthesia and toxic gases in animal experiments. Background technique [0002] In recent years, a large number of animal experiments have been carried out in the laboratory, and the reagents commonly used to anesthetize animals are generally toxic, flammable and explosive organic reagents, such as ether. On the one hand, during the animal anesthesia test, the concentration of ether is too high will directly lead to the death of the animal, which brings uncertainty to the test effect. On the other hand, these organic reagents have low boiling points, are highly volatile, and have special irritating odors. They diffuse or discharge directly into the laboratory or the external environment, directly endangering people's health and causing environmental pollution. [0003] With people's continuous understanding of this field...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the defects of the above-mentioned existing teaching experiments, the object of the present invention is to provide a kind of animal experiment anesthesia toxic gas utilization treatment and purification device, which requires that the concentration of ether cannot be higher than 6.5% for anesthesia experiments, and the whole set of devices monitors the concentration of ether from time to time. And the ether inlet, ether outlet, and air inlet are all equipped with control valves, which can be effectively controlled to meet the test requirements
