Dynamics.
Using two-step method carry out immunochromatography when, the detection method of the utility model is: (1) acquire sample, to sample into
Row processing obtains sample liquid；(2) be loaded: first extruding gasbag, in the case where external force pinches pressure effect, the air bag can be deflated and by gas
Air discharge in capsule；Then the liquid sucting port of quantity tube is put in the sample liquid to be pipetted, come up air bag, removes in external force
Pin rear gasbag restores to the original state automatically and is drawn into sample liquid in each quantity tube in the case where siphon principle acts on, when drawing in quantity tube
Liquid be higher than its top when, can flow in reservoir automatically, make accurately to draw quantitative liquid in quantity tube；Then, it rotates
Reaction chamber, so that reaction chamber is located at first position, the reactive tank is mutually aligned with the connection through-hole and is connected to；By the first tubular
Body is inserted into the second cylindrical body, and the first cylindrical body is made to slide down to the third place, and the test strips in the first cylindrical body are complete
It is placed in the second cylindrical body, test strips are not contacted with the sample liquid in the reactive tank；Quantitative siphoning installation is inserted into detection
In first cylindrical body of mechanism, the connection through-hole that each quantity tube passes through the second cylindrical body lower end is connected to each reactive tank, squeezes gas
Quantitative sample liquid is added into each reactive tank for capsule；Take out quantitative siphoning installation；(3) it detects: revolving reaction chamber, so that reaction
When chamber is located at the second position, the reactive tank and the connection through-hole mutually stagger and close the reactive tank, rock chromatography
Device, so that the antigen mark of the antibody marker for the determinand that the determinand in sample liquid first and in reactive tank is fixed or determinand
Remember object reaction, after reaction, revolving reaction chamber, so that reaction chamber is located at first position, the reactive tank and the connection are logical
Hole is mutually aligned connection, and when pushing the first cylindrical body to four positions, the sample pad of test strips is across the connection through-hole and instead
It answers sample liquid in slot to contact and carries out immunochromatography reaction, visually observe or each detection line signal in instrument scanning chromatographic film
Power determines the number of respective objects substance in sample, and the content of respective objects substance is also higher in signal more weak sample.It is whole
A detection process is carried out in two steps, i.e., immune combination and Immune competition, due to this feature, so reaction is sufficiently, sensitive raising,
Easy to operate, detection is specific antigen-antibody reaction, so having the characteristics that high specificity, accuracy are high.
In the utility model, the quantity tube, holding tank, connection through-hole are identical with the quantity of reactive tank, can be according to reality
Border is set, and is preferably all 2-8, more preferably 4-6.
The utility model is described in detail below with reference to embodiment, embodiment is only the preferred reality of the utility model
