Abstract
The utility model provides a trace application of sample immunodetection card, includes: the body gets stuck to and be fixed in the test paper strip that gets stuck internally, and the getting stuck body is gone up from the last visible window that down is equipped with in proper order, sample application of sample hole and weak solution application of sample hole, and the test paper is from last pads that absorb water that down be equipped with in proper order, nitrocellulose membranes, combination pad and sample pad, nitrocellulose membranes is located visible window department, and the sample pad is located weak solution application of sample hole department. This trace application of sample immunodetection card: increase by an application of sample hole, the reduction is examined time measuring operating personnel and to the loaded down with trivial details process that micro - sample card carries out the dilution outward, has been reduced the probability that operating personnel makes mistakes greatly, the horizontal bar structure that increases under the too much condition of weak solution application of sample, plays certain effect of flowing of holding, reduces weak solution influence to detecting accuracy when too much, the shunting action that the while horizontal bar has enables weak solution homodisperse on the test paper strip and goes upward, promotes the sample evenly to go upward and fully reacts with detection line, matter accuse line, improves detect reagent's stability, accuracy.
Description
Technical field
The utility model relates to technical field of biomedical detection, particularly relates to a kind of micro sample-adding immune detection card.
Background technology
Immune diagnostic reagent is that qualitative or quantitative detection is carried out in the reaction utilizing antigen and specific antibody to be combined with each other, immune diagnostic technique, as one of modern times the sensitiveest, most widely used trace and ultramicron diagnostic techniques, is applied in clinical examination, biological study more and more widely.
External diagnosis reagent especially uses immune detection card to carry out the project detected, carry out trace sample (as: whole blood, serum, blood plasma, urine) when detecting, sample need be carried out outside card dilution mixing to detect again, the process of dilution is except needing other dilution utensil, the process of detection is more made to become loaded down with trivial details, especially, when carrying out a large amount of trace samples and detecting, the probability of operating personnel's error in operation can be increased.If do not dilute outside card, but after the only well of traditional detection card first adds sample, add dilution there will be, dilution makes that the sample part that first adds is up completes immune response, part comes downwards to that sample pad end cannot chromatography be up completes reaction, the sample size of immunity real reaction is inadequate, causes testing result inaccurate.
Utility model content
The purpose of this utility model is to provide a kind of micro sample-adding immune detection card, which solve the impact that need to block the up effect of convection cell in the complicated processes of outer dilution, dilution overload situation when traditional micro-example detects and after using two well, may occur that dilution is up uneven and affect the up effect is combined with detection line, nature controlling line of micro-example chromatography, thus the technical matters of the accuracy of impact detection.
For achieving the above object, the technical scheme that the utility model proposes is:
A kind of micro sample-adding immune detection card of the present utility model, it comprises: casing clamping body, and the test strips be fixed in described casing clamping body, wherein, described casing clamping body is provided with visual windows from top to down successively, sample pipetting volume hole and dilution well, described test strips is provided with adsorptive pads from top to down successively, nitrocellulose filter, pad and sample pad, described nitrocellulose filter is positioned at described visual windows place, and described sample pad is positioned at described dilution well place.
Wherein, described casing clamping body comprises upper shell and lower house, and described upper shell and lower house buckle are installed.
Wherein, the base plate of described test strips is PVC board.
Wherein, the pad of described test strips is coated with the antibody of fluorescent material, color micro-sphere or colloid gold label.
Wherein, described sample pad is glass fibre, dacron or cellulose nitrate.
Wherein, described sample pipetting volume hole and the hole wall of dilution well are ramped shaped.
Wherein, described dilution well is provided with horizontal bar structure, and described horizontal bar structure is at least one fine cord.
Wherein, nitrocellulose filter is provided with nature controlling line and detection line.
The beneficial effect of micro sample-adding immune detection card of the present utility model is: in traditional test card, increase by a well, reduces operating personnel when detecting and, to the complicated processes of diluting outside micro-example card, substantially reduces the probability that operating personnel make mistakes; The horizontal bar structure increased, when dilution overload, plays certain effect storing stream, the impact on detection accuracy when reduction dilution is too much; Simultaneously the shunting action that has of horizontal bar, can make dilution dispersed up in test strips, promote that sample is evenly up and fully react with detection line, nature controlling line, improve the stability, the accuracy that detect reagent.
