Description
Technical field
The present invention relates to gas test technical field, especially a kind of gas species kills
Demodicid mite test device and method.
Background technology
Dust mite is the microorganism that a class has a strong impact on human health, mainly causes abnormal anti-
Answering property disease.Currently, the mite killing test of test gas species is to need to be dissolved in
In organic solvent, in fume hood, remove organic solvent subsequently and adhered to filter paper
On test its effect, owing to not having seal device, during test, the concentration of gas is not
Can keep constant, it is impossible to obtain data the most accurately；Secondly as tester needs
Want organic solvent exposure, chemical substance poisoning or uncomfortable etc., band may be caused
Carry out the harm on healthy；And, if this gaseous matter can not find suitable organic molten
If agent is dissolved, then this test just cannot complete.It addition, the current nothing of mixed gas
Method carries out this class testing.
And for the gas having disinfective action, low dose, low concentration, long effect
The experimental test of time and actual application are that optimal use is used for the mankind
On the way, because it is minimum for the harm of mankind itself, the common public and disappearing
Expense person also is able to for this product accept psychologically.
In view of current situation cannot realize this preferable test and product subsequently
Actual application, it is also difficult to obtain the gas species real action effect for dust mite
Data, therefore have influence on development and the exploitation of this series products.
Summary of the invention
It is an object of the invention to overcome the deficiency of above-mentioned prior art, it is provided that a kind of survey

On.
A kind of gas species mite killing method of testing, is that tested microorganism is put into one is organic
In glass containment housing, then in machine glass containment housing, it is passed through gas to be measured, makes
The respiratory system acting on tested microorganism, and treat micrometer at given time build-in test
Whether biology is killed.During test, on the one hand arrange in lucite containment housing
One desk fan, by the operating of this fan, it is ensured that treating in lucite containment housing
Surveying gas concentration holding constant unanimously, density keeps uniformly；On the other hand by warm and humid
Degree controller controls the ambient temperature and humidity in lucite containment housing so that it is be suitable for
In the test to various microorganisms；Another further aspect for the ease of test after to microorganism
Reclaim, tested microorganism can be loaded in test bag, place into described lucite
Containment housing is tested.
Compared with prior art, present invention have the advantage that the present invention tests device
And method is possible not only to realize acute microorganism testing experimental data, it is also possible to realize Asia
Acute, chronic microorganism testing experimental data.Testing efficiency is high, and test result is accurate
Really, applied widely, the harm for experimenter is little.
Accompanying drawing explanation
Fig. 1 is the structural representation of gas species mite killing of the present invention test device.
Fig. 2 is the structural representation testing bag in the present invention.
Detailed description of the invention
The present invention is described further for the embodiment be given below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of gas species mite killing that the present embodiment provides is surveyed
Electricity testing device, including containment housing 1, test bag 2 and temperature and humidity control instrument 3.Closed box
It is provided with air inlet pipe 4 on body 1, is used for inputting the air of gas to be measured or matched group.
Being additionally provided with opening 5 and cover plate 6 in containment housing 1, opening 5 is used for being placed or taken out
Microorganism to be tested, cover plate 6 is used for sealing opening 5.It is provided with wind in containment housing 1
Fan 7, during test, this fan 7 keeps operating condition, makes the gas to be measured in containment housing 1
Bulk concentration holding is constant unanimously, and density keeps uniformly.
Test bag 2 is used for loading microorganism to be tested, and puts into closed box when test
In body 1.Preferably, test bag 2 is made up of with file 22 filter paper 21.Dust mite is one
The biology that the class bodily form is small, under usual terms, naked eyes are difficult to observe, can only be by aobvious
Micro mirror observes its metamorphosis.It is owing to this type of microorganism bodily form is small, mobile flexible,
The most in addition special handling, it is impossible to ensure to reclaim the most smoothly, thus with filter paper 21 and
File 22 is made for test bag, and when test, gas species can pass through filter paper
21 freely contact with microorganism that (mechanism is: this kind of gas mainly acts on microorganism
Respiratory system), may then determine whether these microorganisms are produced medically
Killing action.After test terminates, can all reclaim all of tested microorganism.
Temperature and humidity control instrument 3 is for controlling the humiture in containment housing 1, and it is concrete
Structure can refer to prior art and designs.Due to microorganism for ambient temperature and humidity have want
Ask (otherwise, the possible mortality of the microorganism of matched group), therefore, humiture control
Instrument 3 processed is a crucial assembly, and its temperature controlling range is :-40 DEG C-105 DEG C；
Humid control scope is: 1%---99%.So, experimental provision of the present invention can
To test all of dust mite quasi-microorganism (such as dust mite, dermatophagoides pteronyssinus, tyrophagus putrescentiae),
And other demodicid mite class such as flour mites, Ticks (such as hard Ticks and soft ticks), insect (such as mosquitos and flies)
Etc..
Preferably, containment housing 1 and upper cover plate 6 thereof all use lucite make and
Become, such that it is able to facilitate the test case that tester observes at any time and grasps in casing.
Preferably, fan 7 and air inlet pipe 4 are arranged on the same sidewall of containment housing 1
On, and fan 7 is positioned at air inlet pipe 4 upper end.Fan 7 can use as required and shake the head
Formula structure or adjustable angle structure, to further ensure that the gas to be measured in containment housing 1
Body density keeps uniformly.It is additionally provided with support 8 in containment housing 1, during test, loads
The test bag 2 having tested microorganism is placed on this support 8.
Preferably, opening 5 and cover plate 6 are arranged on the top of containment housing 1, warm and humid
Degree controller 3 is arranged on the bottom of containment housing 1.Also include one with castor 91
Movable stand 9, containment housing 1 and temperature and humidity control instrument 3 are fixed on this movable stand 9
