Abstract

The utility model discloses an oral-nasal dynamic toxicant exposure cabinet, which comprises a base and a liner arranged on the base; the outside of the liner is provided with an intake manifold; and the air outlet of the intake manifold is provided with an exhaust manifold. Because the air outlet of the intake manifold is provided with the exhaust manifold, when the mouth and the nose of an animal to be contaminated are fixed on the end of the intake manifold to be contaminated, partial poison gas through the intake manifold from the liner is inhaled by the animal to be contaminated, and the rest poison gas and the waste gas exhaled by the animal to be contaminated enter the exhaust manifold and are exhausted, thereby effectively preventing the waste gas produced by the respiration of the animal from returning to the liner of the toxicant exposure cabinet and polluting the inside environment of the liner, and ensuring the accuracy of experimental results.

Description

Mouth and nose formula dynamic contamination cabinet
Technical field
This utility model relates to a kind of toxicant exposure cabinet, particularly a kind of mouth and nose formula dynamic contamination cabinet.
Background technology
Along with the high speed development of social economy and science and technology, the market demand is maked rapid progress, and new biogenetic products are all arranged every day, and new medicine, health product, cosmetics, new chemical fertilizer, pesticide or the like come out.And whether these new things are harmful to human body or environment, then must carry out toxicological experiment to it.Very important means of toxicological experiment are animal contaminated experiments, and contamination has per os (feeding), percutaneous (smearing), realize through respiratory tract modes such as (suctions), and mouth and nose formula toxicant exposure cabinet is exactly a kind of device that is used for the experiment that the suction-type mode contaminates.It can generate a mimic subenvironment, and experimental datas such as concentration of contamination, contamination time, temperature, humidity are provided in real time, for toxicologic study provides in time, accurate, reliable scientific basis.Yet, after the air inlet pipe of present mouth and nose formula toxicant exposure cabinet is inserted into the animal mouth and nose, animal sucks from interior cholic poison, get back in the inner bag by air intake branch and breathe the gas that produces, and contain waste gas such as steam, carbon dioxide and heat in the gas of breathing out, these waste gas can be sucked by other animals again, influence experimental result, pollute the toxicant exposure cabinet internal medium.
The utility model content
In order to solve the above problems, the purpose of this utility model is to provide a kind of can effectively discharge the gas that the contamination animal is breathed out, and prevents that waste gas from returning interior cholic mouth and nose formula dynamic contamination cabinet.
The technical scheme that the invention for solving the technical problem adopted is:
A kind of mouth and nose formula dynamic contamination cabinet comprises base and the inner bag that is arranged on the base, and described interior cholic outside is provided with air intake branch, and the place, gas outlet of described air intake branch is provided with exhaust branch pipe.
As improvement of the technical scheme, be provided with control valve in the described air intake branch.
As further improvement in the technical proposal, described exhaust branch pipe is connected with exhaust main.
As further improvement in the technical proposal, be provided with air extractor in the described exhaust branch pipe.
As further improvement in the technical proposal, be provided with air extractor in the described exhaust main.
As further improvement in the technical proposal, described air intake branch end is provided with the animal fixation clamp.
As further improvement in the technical proposal, described inner bag is provided with watch window.
As further improvement in the technical proposal, described inner bag is provided with sample tap.
As further improvement in the technical proposal, described inner bag periphery is provided with safety guard.
The beneficial effects of the utility model are: owing to be provided with exhaust branch pipe at the end of air intake branch, when contaminate in the place, gas outlet that the mouth and nose of the animal of waiting to contaminate are fixed on the end of air intake branch, the poison part that enters air intake branch from the inner bag animal breath of being waited to contaminate sucks, contaminate waste gas that animal breathes out of rest parts and waiting then enters in the exhaust branch pipe and discharges, prevented effectively that waste gas that animal breath produces from returning in the toxicant exposure cabinet inner bag and cholic internal medium in polluting, guaranteed the accuracy of experimental result.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is this utility model structural representation;
Fig. 2 is the sketch map that this utility model has the animal fixation clamp;
Fig. 3 is that this utility model is brought the gas branch pipe generalized section into;
Fig. 4 is this utility model generalized section.
The specific embodiment
Referring to figs. 1 through Fig. 3, a kind of mouth and nose formula dynamic contamination cabinet comprises base 1 and the inner bag 2 that is arranged on the base 1, and the outside of described inner bag 2 is provided with air intake branch 21, and the gas outlet of described air intake branch 21 is provided with exhaust branch pipe 22.Because the end at air intake branch is provided with exhaust branch pipe, when contaminate in the end that the mouth and nose of the animal of waiting to contaminate are fixed on air intake branch, the poison part that enters air intake branch from the inner bag animal breath of being waited to contaminate sucks, contaminate waste gas that animal breathes out of rest parts and waiting then enters in the exhaust branch pipe and discharges, prevented effectively that waste gas that animal breath produces from returning in the toxicant exposure cabinet inner bag and cholic internal medium in polluting, guaranteed the accuracy of experimental result.
In the present embodiment, be provided with control valve 3 in the described air intake branch 21,, tackle the contamination demand of different occasions with the convenient flow of regulating poison.
In the present embodiment, described exhaust branch pipe 22 is connected with exhaust main 23, when a plurality of air intake branch 21, can easily waste gas be imported in the same pipeline, the unified processing.
In the present embodiment, be provided with air extractor in the described exhaust branch pipe 22.Can in exhaust branch pipe 22, produce negative pressure like this, discharge thereby the waste gas that effectively animal breath is produced is drawn in the exhaust branch pipe 22.
In the present embodiment, be provided with air extractor in the described exhaust main 23.Can in exhaust main 23, produce negative pressure like this, discharge thereby the waste gas that effectively animal breath is produced is drawn in the exhaust main 23.
In the present embodiment, described air intake branch 21 ends are provided with animal fixation clamp 24, can conveniently will be fixed on the end of air intake branch 21 such as animals such as mouse, make its mouth and nose aim at the gas outlet, conveniently experimentize.
With reference to figure 4, in the present embodiment, described inner bag 2 is provided with watch window 25, can conveniently monitor experiment.
In the present embodiment, described inner bag 2 is provided with sample tap 26, can conveniently take out laboratory sample, carries out assay.
In the present embodiment, described inner bag 2 peripheries are provided with safety guard 4, can prevent to occur accident in the experiment, reveal as poison, or animal shake off holder and the people is caused injury.
Certainly, the invention is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
