Description
Technical field
The present invention relates to a kind of gas collecting device, particularly related to a kind of gas sampling enrichment device based on nano material.
Background technology
The human body respiration eudiometry is the noninvasive detection method of a kind of novel safety, in contrast to the biological specimens such as blood, urine, and tidal air is the biological specimen with relatively simple background, without wound, and easy repeated sampling.Be applied to some medical diagnosis on disease in some developed country's the method, and the method is in some major diseases, such as the diagnostic application aspect of cancer also for early diagnosis of cancer, improve result for the treatment of and show tempting application prospect.
Because some the gas componant content with disease association in the characteristics of contaminated respiratory droplets gas are extremely low, usually in the ppm-ppb level, could Accurate Determining after the necessary pre-concentration.
At present, the method for gas concentration mainly contains adsorbent absorption and cold-trap enrichment, and the method for cold-trap operates tediously long and needs special equipment; Sorbing material in the absorption method can be divided three classes, organic polymer, inorganic adsorbent and charcoal base adsorbent.Inorganic adsorbent (such as silica gel, zeyssatite and aluminium oxide) can not be used for breast rail because of its high-hydrophilic.Carbon based material is commonly used, and usable range is narrow, irreversible adsorption causes being difficult to the problems such as desorb but also exist.Activated charcoal for example, although adsorption efficiency is higher, because the analysis condition of activated charcoal is comparatively harsh, general temperature need reach more than 200 ℃ and could fully adsorbent be resolved, this makes troubles for follow-up analyzing and testing.In addition, also have the method for solid-phase microextraction (SPME) sampling, but SPME only adsorbs object by a fibrous probe, the Adsorption Phase finite capacity, therefore high to the requirement of subsequent detection instrumental sensitivity, usually need large-scale precision instrument, testing cost is high.
Summary of the invention
The present invention mainly is the requirement for present market, and a kind of device gas sampling enrichment device based on nano material simple, easy to use that has is provided.
To achieve these goals, the invention provides following technical scheme:
The invention provides a kind of gas sampling enrichment device based on nano material, it comprises gas sampling assembly, gas enriching apparatus and aspiration pump; Described gas sampling assembly comprises gas sampling bag, airbag valve, gas sample mouth and conduit; Described gas enriching apparatus comprises enrichment pipe and nano adsorber; The left end of described conduit is arranged on the described airbag valve; Described gas sample mouth is arranged at the right-hand member of described conduit; Described nano adsorber is arranged in the described enrichment pipe; Described gas sampling assembly is connected with described aspiration pump by described gas enriching apparatus.
In a preferred embodiment of the present invention, described gas sample mouth is arranged at the right-hand member of described conduit by nested mode.
The invention has the beneficial effects as follows: the gas sampling enrichment device based on nano material of the present invention, utilize nano material that human body respiration gas is carried out selectivity or broad spectrum activity absorption, and the object in exhaling carried out enrichment, play concentrated analyzing and testing object, the effect that improves detection sensitivity; In addition, described gas sampling enrichment device based on nano material can with various analysis and detection device couplings, simplified checkout equipment, reduced cost.
Description of drawings
Fig. 1 is the syndeton synoptic diagram that the present invention is based on the gas sampling enrichment device of nano material;
Fig. 2 is the structural representation of gas sampling assembly of the present invention;
The mark of each parts is as follows in the accompanying drawing: 1, gas sampling bag, 2, the airbag valve, 3, the gas sample mouth, 4, conduit, 5, the gas enriching apparatus, 6, aspiration pump.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1 and Fig. 2, Fig. 1 is the syndeton synoptic diagram that the present invention is based on the gas sampling enrichment device of nano material; Fig. 2 is the structural representation of gas sampling assembly of the present invention.
The invention provides a kind of gas sampling enrichment device based on nano material, it comprises gas sampling assembly, gas enriching apparatus 5 and aspiration pump 6; Described gas sampling assembly comprises gas sampling bag, airbag valve 2, gas sample mouth 3 and conduit 4; Described gas enriching apparatus 5 comprises enrichment pipe and nano adsorber; The left end of described conduit 4 is arranged on the described airbag valve 2; Described gas sample mouth 3 is arranged at the right-hand member of described conduit 4; Described nano adsorber is arranged in the described enrichment pipe; Described gas sampling assembly is connected with described aspiration pump 6 by described gas enriching apparatus 5.
During gas sampling, gas sample mouth 3 closely is attached to people's mouth, blows out breathing gas until the complete blow-up of gas sampling bag by the people, airbag valve 2 is fastened to get final product again; During the gas enrichment, described gas enriching apparatus 5 is connected between gas sampling bag 1 and the aspiration pump 6, opens aspiration pump 6, open airbag valve 2, make the breathing gas of collection by the nano adsorber in the described gas enriching apparatus 5, until gas sampling bag is flat.
Described nano adsorber adopts single adsorption agent type of feed or combination loading mode to be arranged in the described enrichment pipe, described nano adsorber comprises nanofiber adsorbent and nano particle adsorbent, the object that is adsorbed on the nano-fiber material does not need exacting terms just can resolve, for example, when object is benzene and chlorobenzene, electro spinning nano fiber just can parse object more than 95% in relatively mild condition (80 ℃), and commercial adsorbent (such as acticarbon) is under same temperature, the parsing amount is less than 20%, resolves the resolution temperature usually need hundreds of degree centigrade fully.The present invention is conducive to simplify gas collection and pick-up unit, can also concentrate the analyzing and testing object, improves the sensitivity that detects; The present invention can also adopt nanofiber adsorbent or the nano particle adsorbent of difference in functionality according to the difference of detected object, also can make up filling, plays the reduction gas-flow resistance, improves the purpose of adsorption efficiency.
