Background technique
Breath test is usually used in the diagnosis of certain diseases, such as helicobacter pylori infections.Its principle is that subject is allowed to take
One contains isotope14C or13Micro- dosage indicia compound urea of C has urease can be with based on the helicobacter pylori in stomach
Decomposing urea generates carbon dioxide and must decompose if containing helicobacter pylori in subject's stomach containing isotope14C or13C's
Micro- dosage urea generation has14C or13The carbon dioxide gas of C, carbon dioxide collecting sample card collect the gas of subject's exhalation
Body carries out isotope detection and is assured that whether subject infects helicobacter pylori.
Collecting sample card is mainly exactly for collecting containing for characteristics of contaminated respiratory droplets14C or13The carbon dioxide gas of C, it is existing
Exhalation test card common ground is the both ends that card body is arranged in air inlet and gas outlet, and carbon dioxide gas is from the intracorporal absorber of chamber
Surface is flowed through, and realizes the acquisition of carbon dioxide gas in range in a limited space, and the intracorporal absorbing sheet of chamber substantially all uses alkali
Property absorption reagent is coated on the mode of absorbing sheet, and absorption reagent mostly uses lithium hydroxide, calcium hydroxide, sodium hydroxide, calcium oxide,
Such alkaline reagent such as potassium hydroxide all has moisture absorption, easily knot lump, causes to wrap up14C or13C soft beta ray, corrosivity are inhaled by force
Receipts ability is weak to cause detector to be not easy to detect, and reduces the detection benefit of helicobacter pylori detector, therefore designs and develops one kind
Facilitate detection non-corrosive, absorbability is strong, and collecting sample card made of the carbon dioxide absorbing material of environmental protection has weight
Want meaning.
Summary of the invention
Aiming at the deficiencies in the prior art, the utility model provides a kind of non-corrosive, environmentally friendly, efficient pylorus spiral shell
Spinner handle bacterium detector collecting sample card.
For above-mentioned purpose, technical solutions of the utility model are as follows:
A kind of helicobacter pylori detector collecting sample card, including air inlet (1), indicating window (3), absorbing sheet (7) and
Gas outlet (8) is formed with the cavity (2) of airflow channel between the air inlet (1) and gas outlet (8)；Indicating window (3) position
Between air inlet (1) and absorbing sheet (7), absorbing sheet (7) two sides are equipped with detection window (9), and the surface of each detection window (9) is equipped with
The transparent membrane (6) of low β absorptivity；It is formed between absorbing sheet (7) and the transparent membrane (6) for detecting window (9) and absorbs air-flow sky
Between.
Further, the absorbing sheet (7) is special at felt by high-efficiency activated Carbon fibe, and activated carbon fibre has the special feature that
Be that pore-size distribution is narrow, and uniform micro is abundant, there is big reference area, high absorption property, unique surface chemical property and
Adsorption rate.
Further, entirety of the collecting sample card in addition to air inlet (1) and gas outlet (8), including transparent detection
Window (9) is all sealing.
Further, the absorbing sheet (7) is clamped and fastened on detection window (9) inside by two mosaic pieces.
Further, the collecting sample card is integrally made of upper and lower two mosaic piece, inside have respectively at air inlet and
The connected recess channels (10) in gas outlet, (10), which are equipped with, in each recess channels is connected to the ventilative of the mosaic piece inner side and outer side
Through-hole (5).
Further, the detection window (9) be equipped with transparent membrane (6), the transparent membrane (6) its have lower β particle
Absorptivity guarantees that tested β particle can be normally through the transparent membrane.
Further, multiple ventilative through holes (5) and recess channels of detection window (9) in inlet and outlet directional spreding
(10), guarantee that the air-flow of incoming call stays the surface through absorbing sheet (7) by ventilative through hole (5), recess channels (10).
The utility model has the advantages that the utility model is by making the carbon dioxide gas of incoming call flow through the active carbon of detection window relative position
Absorbing sheet surface made of fiber makes absorbing sheet absorbing carbon dioxide gas, to improve the collecting efficiency of carbon dioxide gas
And the accuracy of detection.
