Detailed Description

The technical solutions in the embodiments of the present invention are described below clearly and completely, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 to 4, a reagent casing comprises a gland 2 and a bottom plate 1, wherein a placing groove 1-4 for placing a reagent strip (not shown in the figures) is arranged on the bottom plate 1, two sides above the placing groove 1-4 are provided with protrusions 1-2, and the gland 2 is assembled between the two protrusions 1-2 in an interference fit mode.

Furthermore, the placing groove 1-4 is arranged at one end of the bottom plate 1, and the other end of the bottom plate 1 is a handheld end, so that the reagent shell can be conveniently inserted into an analysis instrument for analysis. The bottom plate 1 is provided with at least one detection hole 1-1 communicated with the placing groove 1-4, the number of the detection holes 1-1 corresponds to the number of detection items of the reagent strip, the single-joint reagent strip corresponds to one detection hole, the double-joint reagent strip corresponds to two detection holes, the triple reagent strip corresponds to three detection holes, and so on. The gland 2 is matched with the placing groove 1-4, and the gland 2 is provided with a sample adding hole 2-1 communicated with the placing groove 1-4. The gland 2 is matched with the placing grooves 1-4, namely the size of the gland 2 is just required to be ensured that the gland 2 is assembled between the two convex parts 1-2 in an interference fit manner, the reagent strip can be sealed, the size of the gland is the same as that of the bottom plate, and raw materials are saved.

Further, at least two pairs of the convex parts 1-2 are symmetrically arranged at the left side and the right side of the upper part of the placing groove 1-4 along the length direction, and preferably, two pairs of the convex parts 1-2 are arranged. Gland 2 interference fit assembles to between two pairs of bulges 1-2 for gland 2 and bottom plate 1's connection is more firm, has improved the reliability of both connections.

Furthermore, the convex parts 1-2 are arranged at the top of the bottom plate 1 and positioned at the left side and the right side of the placing groove 1-4 along the length direction, a groove 1-3 is arranged between two adjacent convex parts 1-2 at the same side, and extending parts 2-3 matched with the groove 1-3 are arranged at two sides of the gland 2; the extension parts 2-3 and the grooves 1-3 are matched with each other to prevent light from penetrating from a gap between the gland 2 and the bottom plate 1, so that the whole shading effect is improved, and the detection precision of the reagent strip is improved.

Furthermore, the end part of the convex part 1-2 far away from the bottom plate 1 is provided with a hook body 1-5 facing the placing groove 1-4, and after the gland 2 is assembled between the convex parts 1-2 at the two sides in an interference fit manner, the hook body 1-5 fixes the gland 2 to avoid the gland 2 from falling off.

Furthermore, convex strips 2-4 are arranged on two sides of one surface, facing the placing groove 1-4, of the pressing cover 2, the convex strips 2-4 extend along the length direction of the pressing cover 2, and when the pressing cover is closed, the convex strips 2-4 are attached to the inner wall of the placing groove 1-4; after the gland 2 is assembled between the two convex parts 1-2 in an interference fit manner, light cannot penetrate through a gap between the gland 2 and the bottom plate 1, the whole shading effect is improved, and therefore the detection precision is reduced due to the fact that the light influences reagent strips in the placing groove.

Furthermore, the side surfaces of the two sides of the gland 2 along the length direction are inclined surfaces 2-5 which incline inwards from the top to the bottom. When the gland 2 is pressed between the two protrusions 1-2, the inclined surface 2-5 facilitates the pressing of the gland 2 and guides the pressing, and the inclination of the inclined surface 2-5 is not particularly limited, and preferably, the angle α between the inclined surfaces is 20 to 50 °.

Furthermore, the pressing cover 2 and the bottom plate 1 are made of shading materials, preferably black shading materials are adopted, so that the reagent strips in the placing grooves 1-4 are shaded, the interference of a background can be reduced, and the detection precision is improved.

Further, a cavity bulge 2-2 protruding outwards is arranged on the gland 2, and a sample adding hole 2-1 is arranged on the bulge 2-2; the cavity bulge 2-2 covers the whole reaction area of the reagent strip, and the sample chromatography speed and the sample amount are more effectively controlled.

Furthermore, the front end and the rear end of the top of the placing groove 1-4 are provided with limiting grooves 1-6 for limiting the gland 2, and the limiting grooves 1-6 are communicated with the placing groove 1-4; the limiting grooves 1-6 can accurately position the whole gland 2.
