(1) the detection index is flexibly set: a plurality of groups of detection units are adopted, and each detection unit can be provided with an independent sample inlet, so that simultaneous detection of multiple indexes (including TAT, PIC, TM and t-PAI-C) in the thrombus related diseases can be realized, and the method is also suitable for single detection of single index or single detection of a plurality of indexes; the multiple groups of detection units can be identified by colors or letters so as to avoid errors caused by detection negligence;

(2) the operation is simple: the processed sample solution is only required to be dripped into a detection sample adding groove (if single index or a plurality of indexes are separately detected, the sample solution is only required to be dripped into corresponding sample feeding holes), and after a certain reaction time, the detection result can be quickly obtained by matching with corresponding detection equipment;

(3) the detection sample feeding holes of the detection units are arranged at equal intervals, so that the consistency of the sample feeding amount and the sample feeding time of the detection units is ensured, the reliability of a detection result is ensured to the maximum extent, the sensitivity is high, and the errors in batches and among batches are small, thereby providing great convenience for clinical use; moreover, the volume is small, the carrying is convenient, the storage is easy, and the application and the popularization of a primary hospital are facilitated; in addition, the preparation method is simple, the technology is mature, and batch production can be realized;

(4) the fixed grooves are mutually spaced, so that the test strips are mutually spaced, the detection items cannot be subjected to cross contamination, and the detection result cannot be deviated due to mutual influence of chromatographic action; simultaneously, one side of the lower surface of bottom plate corresponds every fixed slot and also is equipped with corresponding draw-in groove, can effectively prevent that the reagent card from placing the dislocation when arranging check out test set in.

Detailed Description

The first embodiment is as follows:

as shown in fig. 1-4, the present embodiment is a reagent card for joint inspection of six indexes of thrombus related diseases, which includes a card sleeve and test strips fixed in the card sleeve, wherein the card sleeve is divided into a panel 1 and a bottom plate 2 matched therewith, the panel and the bottom plate are connected by a protrusion and a groove buckle around the panel and the bottom plate, six fixing grooves 2-1 are formed in the bottom plate, a test strip 3, which is respectively 6 test strips of DD, TM, TAT, PIC, FDP, and tpa i.c, is fixedly adhered in each fixing groove, a test window 1-1 and a sample inlet 1-2 are formed in the panel at a position corresponding to each test strip, and a hand-held area 1-3 with uniformly arranged bumps is formed in one side of the panel for easy holding and convenient operation. In order to improve the detection efficiency, the reagent card for the six-index joint inspection of the thrombus related diseases is used in cooperation with an analyzer of an immune system, in order to prevent the reagent card from being misplaced when the reagent card is placed in the analyzer, a concave point 2-2 for positioning is arranged on one side of the lower surface of the bottom plate, and a corresponding clamping groove 2-3 is also arranged corresponding to each fixing groove.

As shown in fig. 5, the test strip 3 is a fluorescence immunochromatographic test strip, and is formed by sequentially overlapping and adhering a sample pad 301, a fluorescence label pad 302, a nitrocellulose membrane 303, and a water absorbent paper 304 to a bottom substrate 305. The fluorescent substance labeling pads 302 of the 5 test strips are respectively coated with a DD antibody marker, a TM antibody marker, a TAT antibody marker, a PIC antibody marker, an FDP antibody marker and a tPAI.C antibody marker, and the nitrocellulose membrane 303 is respectively coated with a DD antibody, a TM antibody, a TAT antibody, a PIC antibody, an FDP antibody and a tPAI.C antibody to form a detection area and a goat anti-mouse IgG antibody to form a control area. The detection window 1-1 on the panel corresponds to the detection area of the detection test strip, and the sample inlet 1-2 corresponds to the sample pad 301.

The reagent card described in this embodiment is used for detection at room temperature, and the detection steps are as follows:

when the kit is used, a sample liquid is dripped on a sample pad through a sample inlet hole 1-2, the sample liquid flows towards one side of absorbent paper under the capillary action, when DD, TM, TAT, PIC, FDP and tPAI.C are contained in the sample liquid, DD, TM, TAT, PIC, FDP and tPAI.C respectively form an antigen-antibody complex with a TM antibody, a TAT antibody, a PIC antibody, an FDP antibody and a tPAI.C antibody which are marked by a fluorescent substance, and the antigen-antibody complex continuously flows towards one side of the absorbent paper along with the chromatography action to reach the DD antibody, the TM antibody, the TAT antibody, the PIC antibody, the FDP antibody and the tPAI.C antibody coated in a detection area T to form an antibody-antigen-antibody complex, and an aggregate of the fluorescent substance with the antibody-antigen-antibody complex is formed at the T. And the fluorescent substance which is not combined with the monoclonal antibody continuously swims to one side of the absorbent paper, and when the fluorescent substance reaches the quality control band C, the goat anti-mouse IgG antibody is combined with the mouse-derived monoclonal antibody on the fluorescent substance, so that the fluorescent substance is gathered at the position of the quality control band C.

Finally, it should be noted that the above only illustrates the technical solution of the present invention, but not limited thereto, and although the present invention has been described in detail with reference to the preferred arrangement, it will be understood by those skilled in the art that modifications or equivalent substitutions may be made thereto without departing from the spirit and scope of the technical solution of the present invention.
