Description
Technical field
The utility model belongs to animal model constructing technology field, and in particular to a kind of for building animal injury model
Fine particle suction apparatus.
Background technology
PM2.5 is also referred to as inhalable lung particulate matter, refer in total air suspended particulates aerodynamic diameter be less than or
Particulate matter equal to 2.5 μm.Although PM2.5 is the little component of content in earth atmosphere composition, it is to environmental quality, sky
Gas visibility and health etc. have important influence.There are some researches show, the particulate matter residence time in an atmosphere is long,
Can fed distance it is remote, coverage is big, and the smaller harm to health of particle size is bigger because diameter is smaller,
Particulate matter enters the position of respiratory tract and depth is presented negatively correlated with diameter:The particulate matter of usual 10 μ m diameter is usually deposited at
Respiratory tract, and less than 2 μm of be deep into bronchiole and alveolar.Compared with thicker Atmospheric particulates, PM2.5 particle diameters are more
It is small, after fine particle is into human body to alveolar, the ventilatory function of lung can be directly affected, body is easily in anaerobic condition, it is long
Phase exposure can trigger cardiovascular disease and breathing problem, additionally, organic pollution and the huge sum of money such as PM2.5 easily absorbing multiring aromatic hydrocarbons
Category, makes carcinogenic, teratogenesis, mutagenic probability significantly raised, thus influence to health and atmosphere quality is bigger.
It is reported that, when the concentration of PM2.5 in air is higher than for a long time 10, can bring about the rising of mortality risk;Concentration often increases
10, total mortality risk rises 4%, and the mortality risk that heart and lung diseases bring rises 6%, and the mortality risk that lung cancer is brought rises 8%.
United Nations Environment Programme's announcement in 2012《Global environment prospect 5》Point out there are 700,000 people to die from because caused by ozone every year
Respiratory disease, has nearly 2,000,000 premature death case relevant with Particulate Pollution.《NAS's proceeding》
(PNAS) research report has also been delivered, has been claimed in report, the average life span of the mankind is because air pollution has been likely to shorten 5 years
Half.
The report of World Bank's issue shows that, by premature death number caused by outdoor air pollution, average out to is daily
1000 people, the people for having 35 to 400,000 every year is faced with death.Specifically, early in 1997, the World Bank is just pre- in respect of in 50,000
Compatriots' premature death because of air pollution.On the whole, this part report finds that the air pollution of China causes city dweller's
Life-span reduces 18 years.
Air is pointed out on October 17th, 2013, subordinate international cancer research institution of World Health Organization issue report first
Pollution is carcinogenic to the mankind, and regards it as universal and main environmental carcinogen.Air pollution is used as an overall carcinogenic factor quilt
Propose, its injury to human body is probably the result that several big pollutant as contained by it is acted on simultaneously.
PM2.5 can produce the damage of multiple organ, Mutiple Targets to body, be a chronic, long-term pathological change process, because
This is in terms of research PM2.5 mechanism and its countermeasure, and it is molten that foundation gives chronic PM2.5 gas in the case where PM2.5 onset environments are simulated
Glue exposes to form animal injury model, can more really reflect pathologic process, and this also turns into an important side of PM2.5 researchs
To.But the existing fine particle suction apparatus for building animal injury model is not suitable for simulating PM2.5 gray haze damage models
Structure, this mainly has following reason:1st, existing special animal particle inhalation device is generally required and carried out under subnormal ambient
Treatment, typically results in that its structure is complex, high cost;2 and researched and developed from pelleting suction apparatus more use Neulized inhalation
Mode, can cause build model humidity it is too high, it is impossible to simulate normal PM2.5 gray hazes environment, be not particularly suited for PM2.5 moulds
The research of type;And lasting, the stabilization, suction source that concentration is controllable cannot be formed more than the existing suction apparatus of pelleting certainly, cause
The fine particle concentration of animal suction is unstable;And general many of home-made contrivance carries out an animal operation or many animals are easy
Squeeze a ball, have a strong impact on the suction effect of animal;And discarded fine particle is not reclaimed, easy two secondary environment is dirty
Dye, also damages to experimenter.It can be seen that, either the particle suction apparatus of existing shaping or it is known as needed from
The suction apparatus of row research and development, the structure of the animal injury model needed for influence for research PM2.5 is not applied to simultaneously, serious shadow yet
The further investigation of PM2.5 is rung.
