Description
Technical field
The utility model relates to a kind of drug volatilization gas toxicity test device, the simple and easy experimental box of particularly a kind of volatility preparation toxicity.
Background technology
At present, in the preparation of medicine is produced,, must do experiment to volatilization gas for volatilization gas is arranged, be determined by experiment whether toxic, and the size of toxicity.At present, generally adopt a capsule or uncovered flask, glass tube, toy is put into capsule or uncovered flask, glass tube, put the vessel of containing volatilizer again, freely breathe volatilization gas by toy, see the wiping toy and be subjected to malicious situation, determine toxicity then.This method is simple, but the deficiency that exists is: because the gas that volatilizes can directly enter atmosphere, only some is absorbed by toy, thus can not quantitative analysis, influence experiment effect; In addition,, influence its physiological function, also make experiment effect be subjected to certain influence,, directly distribute in the atmosphere, can produce certain harm the staff if volatilization gas toxicity is bigger because the scope of activities of toy is less.In order to prevent that poisonous volatilization gas from directly distributing in the atmosphere, the employing that has airtight measure, but this closed container has influenced the eupnea of toy again, causes anoxic to poison, and has also influenced the accuracy of experiment effect.
Summary of the invention
The purpose of this utility model is to provide a kind of normal life environment that neither influences toy, does not influence experiment effect again, can also make the simple and easy experimental box of volatility preparation toxicity of quantitative test.
For reaching above purpose, the technical scheme that the utility model adopted is: the simple and easy experimental box of this volatility preparation toxicity, by transparent casing, transparent case lid and O-ring seal constitute, O-ring seal is stuck in the mouth of transparent casing along inboard, transparent case lid covers on the mouth of transparent casing, and seal by O-ring seal, it is characterized in that in the through hole of transparent case lid middle part, inserting test tube, and seal by O-ring seal, fill volatilizer in vitro, middle part at test tube is provided with evaporation hole, the upper surface of volatilizer is lower than the position of evaporation hole, fills in rubber plug on test tube suitable for reading, is provided with heating rod in rubber plug, left end at transparent casing is provided with venthole, be provided with mini fan in venthole, venthole is connected with the solvent basin by conduit, and insert in the solvent of solvent basin the end of conduit, right-hand member at transparent casing is provided with air admission hole, is provided with the isobaric pressure-regulating valve of atmosphere in air admission hole.
The utility model is also implemented by following measure: the evaporation hole at described test tube middle part is established 4-8, equidistantly arranges in the form of a ring; The isobaric pressure-regulating valve of described atmosphere, constitute by valve body, ball, bell mouth and air inlet runner, bell mouth is located on the air inlet runner, ball places in the bell mouth, gravity shutoff air inlet runner by ball, can promote the gas flow in the transparent casing by bleeding, simultaneously, when the air pressure in the transparent casing during less than the external atmospheric pressure of glass box, ball rolls along lural skew wall, air inlet runner is by open-minded, and the external atmosphere of glass box enters in the transparent casing, makes the internal and external pressure balance of transparent casing; Described transparent casing is a rectangular box, and long is 30-50cm, and wide is 20-30cm, and toy has bigger activity space, and can put many.
The beneficial effects of the utility model are, compare with present use capsule or uncovered flask, the method that glass tube is made toxicity test, not only simple or also have sealing property, but also do not influence experiment effect, free from environmental pollution, the normal life environment that do not influence toy, can also do quantitative test.Can be widely used in volatility preparation toxicity test.
Description of drawings
