The part of the pipe body of the pipe in the shell is of a branch structure, the number of branches corresponds to the number of test strips, all branches are equal in length, the end ports of the branches are bevel ports, namely the cross section of the port is not the pipe, the branch of the pipe is lapped with a sample loading pad of the test strip, specifically, the inclined plane of the branch port is lapped with the sample loading pad, and the overlapping part is 0.3-0.6cm. The partial design solves the problem of uneven sample loading among different test strips.
The shell is formed by buckling an upper part and a lower part, the upper part is a shell cover, the lower part is a shell bottom, and the two parts can be buckled and combined into a whole in a common mode, such as a convex edge and a concave edge which are matched with each other on four sides, and/or a columnar bulge and a concave hole which are arranged in the shell.
The inside of the shell bottom is provided with a clamping groove for fixing the test paper strip, and the clamping groove can be a square space formed by 4 protruding edges which are connected end to end in a surrounding mode; the test strip is preferably formed by encircling 2 strip-shaped bulges which are positioned in specific positions in half and half, and bulges are arranged on opposite sides of the paired strip-shaped bulges, so that the test strip can be well fixed and cannot move and fall off even if the bottom of the test strip loses the horizontal position; the single strip-shaped bulge is arranged at the tail end of the shell, 2 columnar bulges are arranged opposite to the strip-shaped bulge, and the distance between the 2 columnar bulges is slightly smaller than the diameter (outer diameter) of the catheter branch, so that the position and the direction of the catheter branch are fixed, and the position of the test strip is limited. The clamping grooves are arranged in a plurality of parallel; however, in order to ensure that the lengths of the branch port of the catheter and the overlapping part of the sample loading pad meet the requirements, the positions of the columnar protrusions and the opposite strip-shaped protrusions can be properly adjusted towards the tail end direction of the shell.
The observation window is arranged on the shell cover and above the detection pads of the test strips, letters T and C are marked beside the observation window, and the name or abbreviation of the detection marker corresponding to the test strip is marked at the top end of the observation window.
Due to the implementation of the technical scheme, compared with the prior art, the utility model has the following advantages:
the utility model has the innovation point that the utility model provides the blood sampling and detection integrated reagent capable of simultaneously detecting a plurality of markers for the first time, simplifies the procedures of blood sampling, quantitative sampling and sample loading of the conventional reagent, and is convenient for realizing detection in special scenes; and through the improvement to the test strip, the detection time is further shortened, no instrument or equipment is needed, the detection result can be known according to the color development condition of the corresponding positions of T and C, and the whole process can be completed within 10 minutes. Meanwhile, the use of various disposable consumables is also saved. The detection reagent disclosed by the utility model is simple to operate, does not need equipment to be matched for interpretation, and can be used for self-testing and understanding of the physiological index state at home.
