Description
Technical field
The utility model relates to gas test technical field, and especially a kind of gas species kills mite proving installation.
Background technology
Dirt mite is the microorganism that a class has a strong impact on human health, mainly causes allergic disease.Current, test gas class material kill mite test be need to be dissolved in organic solvent, in fuming cupboard, remove organic solvent subsequently and adhered on filter paper and test its effect, owing to there is no leakproofness device, during test, the concentration of gas can not keep constant, cannot obtain data very accurately; Secondly, because tester needs organic solvent exposure, chemical substance may be caused poisoning or uncomfortable, bring the harm in health; And if this gaseous matter can not find suitable organic solvent to dissolve, then this test just cannot complete.In addition, mixed gas cannot carry out this class testing at present.
And for there being the gas of disinfective action, low dose, low concentration, the experimental test of long action time and practical application are optimal uses for the mankind, also can accept psychologically for this product because its harm for mankind itself is minimum, the common public and consumer.
In view of current situation cannot realize this desirable test and product practical application subsequently, be also difficult to obtain gas species for the real action effect data of dirt mite, therefore have influence on the manufacture and exploit of this series products.
Utility model content
The purpose of this utility model is the deficiency overcoming above-mentioned prior art, provides a kind of testing efficiency high, and test data is accurate, applied widely, and endangers little gas species for experimenter and kill mite proving installation.
For achieving the above object, the utility model have employed following technical scheme:
A kind of gas species kills mite proving installation, comprises containment housing, test pack and temperature and humidity control instrument; Described containment housing is provided with draft tube, is used for inputting the air of gas to be measured or control group; Described containment housing is also provided with opening and cover plate, and described opening is used for placing or taking out microorganism to be tested, and described cover plate is used for sealing described opening; Be provided with fan in described containment housing, during test, this fan keeps operating condition, and make the gas concentration to be measured in containment housing keep unanimously constant, density keeps evenly; Described test pack for loading microorganism to be tested, and puts into containment housing when testing; Described temperature and humidity control instrument is for controlling the humiture in containment housing.
Further, described test pack is made up of filter paper and file, and during test, the gas in containment housing enters test pack through filter paper and contacts with tested microorganism.
Further, described containment housing and upper cover plate thereof all adopt organic glass to be made.
Further, described fan and draft tube are arranged on the same sidewall of containment housing, and fan is positioned at draft tube upper end.
Further, described fan adopts head-swinging type structure or adjustable angle structure.
Further, be also provided with support in described containment housing, during test, described test pack is placed on this support.
Further, described opening and cover plate are arranged on the top of containment housing.
Further, described temperature and humidity control instrument is arranged on the bottom of containment housing.
Further, also comprise one with the movable stand of castor, described containment housing and temperature and humidity control instrument are fixed on this movable stand.
Compared with prior art, the utility model tool has the following advantages: this novel test device and method not only can realize acute microorganism testing experimental data, can also realize subacute, chronic microorganism testing experimental data.Testing efficiency is high, and test result is accurate, and applied widely, the harm for experimenter is little.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model gas species kills mite proving installation.
Fig. 2 is the structural representation of test pack in the utility model.
Embodiment
The embodiment provided below in conjunction with accompanying drawing is described further the utility model.
As depicted in figs. 1 and 2, a kind of gas species that the present embodiment provides kills mite proving installation, comprises containment housing 1, test pack 2 and temperature and humidity control instrument 3.Containment housing 1 is provided with draft tube 4, is used for inputting the air of gas to be measured or control group.Containment housing 1 is also provided with opening 5 and cover plate 6, opening 5 is for placing or taking out microorganism to be tested, and cover plate 6 is for sealing opening 5.Be provided with fan 7 in containment housing 1, during test, this fan 7 keeps operating condition, and make the gas concentration to be measured in containment housing 1 keep unanimously constant, density keeps evenly.
Test pack 2 for loading microorganism to be tested, and puts into containment housing 1 when testing.Preferably, test pack 2 is made up of filter paper 21 and file 22.Dirt mite is the biology that a class bodily form is small, and under usual terms, naked eyes are difficult to observe, and can only observe its metamorphosis by microscope.Because this type of microorganism bodily form is small, flexibly mobile, not special processing in addition, cannot ensure to reclaim smoothly after experiment, therefore made test pack with filter paper 21 and file 22, when testing, gas species freely can be contacted with microorganism by filter paper 21 (mechanism is: this kind of gas mainly acts on the respiratory system of microorganism), then can determine whether these microorganisms generation killing action medically.After test terminates, all can reclaim all tested microorganisms.
Temperature and humidity control instrument 3 is for controlling the humiture in containment housing 1, and its concrete structure can refer to prior art to design.Because microorganism has requirement (otherwise, the microorganism of control group may mass mortality) for ambient temperature and humidity, therefore, temperature and humidity control instrument 3 is crucial assemblies, and its temperature controlling range is :-40 DEG C-105 DEG C; Humid control scope is: 1%--99%.So, the utility model experimental provision can test all dirt mite quasi-microorganisms (as dust mite, dermatophagoides pteronyssinus, tyrophagus putrescentiae), and other mite classes are as flour mite, tick (as hard tick and soft ticks), insect (as mosquitos and flies) etc.
Preferably, containment housing 1 and upper cover plate 6 thereof all adopt organic glass to be made, thus tester can be facilitated to observe at any time and grasp the test case in casing.
Preferably, fan 7 and draft tube 4 are arranged on the same sidewall of containment housing 1, and fan 7 is positioned at draft tube 4 upper end.Fan 7 can adopt head-swinging type structure or adjustable angle structure as required, to guarantee that the gas density to be measured in containment housing 1 keeps evenly further.Also be provided with support 8 in containment housing 1, during test, the test pack 2 being mounted with tested microorganism is placed on this support 8.
Preferably, opening 5 and cover plate 6 are arranged on the top of containment housing 1, and temperature and humidity control instrument 3 is arranged on the bottom of containment housing 1.Also comprise one with the movable stand 9 of castor 91, containment housing 1 and temperature and humidity control instrument 3 are fixed on this movable stand 9, thus convenient mobile described proving installation.
As described above, be only preferred embodiment of the present utility model, the scope of the utility model enforcement can not be limited with this, namely the simple equivalence change generally done according to the utility model claim and utility model description with modify, all still belong in scope that the utility model patent contains.
