Description
Technical field
The utility model relates to the proving installation that a kind of human body sucks objectionable impurities.
Background technology
At the beginning of 2013, media are produced the event that opaquing fluid poisons small white mouse with poison and are caused very large social repercussion, and opaquing fluid is the school supply and stationery that adolescent student utilization rate is higher, and the security risk therefore assessing solvent is just extremely necessary.At present, the solvent that opaquing fluid uses mainly contains 3 classes: trichloroethanes, methylcyclohexane and cyclohexane.But there is the bad producer of minority to reduce costs the solvent using the better benzene homologues organic solvent of dissolubility as opaquing fluid.Benzene homologues is a kind of supervirulent organic solvent, if the solvent used or adjuvant do not take off benzene thoroughly, product residue just may be made to have benzene, toluene and dimethylbenzene.According to GHS criteria for classification, toluene, dimethylbenzene belong to Category 2, experimentally the evidence of zooscopy, can suppose the material of likely harm humans health after repeating contact.In addition, in toy, existence causes in irritated spices, furniture containing poisonous and harmful substances such as formaldehyde volatilizations.Therefore, carry out special simulation human body respiration to collect test analysis and carry out harmfulness assessment to them there is very important Research Significance.
Current standard GB/T 21027 only makes limitation regulation for benzene, toluene and dimethylbenzene, and the assay method more complicated provided; China National Light Industrial Products Department industry standard QB2665 and QB/T4154 only makes limitation regulation to benzene, does not provide concrete assay method.Therefore, necessary a kind of effective analytical approach and the proving installation set up is to realize the mensuration that human body sucks harmful substance contents.
The assay method of benzene homologues organic solvent mainly contains vapor-phase chromatography, GC-MS(gas chromatography-mass spectrography), thermal desorption-gas chromatography-mass spectrum and liquid phase chromatography.In addition, packed column method, operating process is loaded down with trivial details; Head space is if benzene homologues content is higher in sample, larger on measurement result impact; The method of other also useful charcoal absorption, solvent elutions, but the method not only consumes a large amount of solvent, and eluent also has certain toxicity, all produces harmful effect to human body and environment, more seriously the method is large to low concentration sample analytical error, and detection limit is higher.
Existing human body suction gas content of material analyzes Patents to be had:
CCS Wuhan Code and standard ox person of outstanding talent application " in suction gas carbon dioxide content proving installation " (number of applying for a patent: 201220696231.7; Open notification number: CN202974990U; Statutory status: authorize) in, mainly consider the proving installation of carbon dioxide content in the suction gas of simulation artificial lung function, although it is when simulation artificial lung, there is no not action space, and gas flow is at the uniform velocity controlled during artificial respiration, but its structural disadvantages is carbon dioxide content directly carries out test analysis in each respiratory, and the total content can not tested after a period of time accumulation, namely there is no thermal desorption device and chromatographic analysis device, objectionable impurities activity can not be sucked and content is measured by simulated humanbody.
" gas componant pick-up unit " (number of applying for a patent: 201320456458.9 of the Song Jiayong of Huainan Mining (Group) Co., Ltd., virgin principal, Zhu Chao, Wang Fei application; Open notification number: CN203422363U; Statutory status: authorize) in, mainly consider and solve the problem that in prior art, gas detecting instrument cannot detect for the gas in himself unapproachable space.And human body sucks in the gas of objectionable impurities just from space residing for detecting instrument self, the gas beyond space residing for himself not should and need not do to consider.
" a kind of inhalation anaesthesia apparatus " (number of applying for a patent: 201120421312.1 of Liu Ruiquan, Han Feng application of the People's Hospital of Anqiu City; Open notification number: CN202277596U; Statutory status: authorize) in, mainly consider patient in oxygen uptake anaesthesia process, how to make the inhalation anaesthesia apparatus that depth of anesthesia is more easy to control, anaesthetic effect is more continual and steady, patient comfort is higher.Take except structure and put and the hierarchy of control, it can not solve mensuration and the problem analysis of gas componant content.
Can see also there is no the special device that can carry out regulating respiratory capacity and respiratory rate for different crowd and breathing characteristic at present from above-mentioned introduction, also not be specifically designed to the device sucking objectionable impurities in simulation and assessment human body respiratory.And the device designed by the utility model can be widely used in all kinds of objectionable impurities by suction enter human body content measuring and assessment in.
