The following embodiments will help those skilled in the art to further understand the present utility model, but do not limit the present utility model in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several changes and improvements can still be made. These all belong to the protection scope of the present utility model.

[0027] As Figures 1-5 shown, a household reagent card provided according to the present utility model includes: an upper cover, a lower shell, and a test strip. The upper cover is fixedly connected to the lower shell and a cavity is formed inside. The test strip is fixedly installed in the cavity. A sample addition hole 1 and an observation window 2 corresponding to the test strip are provided on the upper cover. A handheld part 3 is provided at one end of the upper cover close to the sample addition hole 1. One or more groups of anti-slip structures 4 are provided on the handheld part 3. Protrusions 5 are provided on both the upper and lower sides of the sample addition hole 1. The protrusion 5 between the sample addition hole 1 and the observation window 2 completely separates the sample addition hole 1 and the observation window 2. The protrusion 5 between the sample addition hole 1 and the handheld part 3 completely separates the sample addition hole 1 and the handheld part 3.

[0028] An installation groove for accommodating the test strip is provided inside the lower shell. The test strip includes, in sequence: a sample filtering pad 11, an NC membrane 12, and a water absorption paper 13. The sample addition hole 1 is correspondingly arranged with the sample filtering pad 11, and the observation window 2 is correspondingly arranged with the NC membrane 12.

[0029] The anti-slip structure 4 is provided on the front and / or side of the handheld part 3. The side includes the left and right sides and the lower side.

[0030] The anti-slip structure 4 includes, but is not limited to, a plurality of circular protrusions, triangular protrusions, and diamond-shaped protrusions arranged in an array. In other specific implementation manners, the anti-slip structure 4 can also be other shapes and structures, or a combination of multiple shapes, and can be adjusted according to actual situations.

[0031] In a specific embodiment, a handheld part 3 is provided at one end of the upper cover close to the observation window 2, and one or more groups of anti-slip structures 4 are provided on the handheld part 3. In other specific embodiments, the handheld parts 3 can be provided on both the upper and lower sides of the upper cover, and can be pinched and held from above and below or from both sides, which is convenient for users with different habits.

[0032] The shape of the sample adding hole 1 is an irregular circle, including but not limited to a shape similar to a runway shape, which can reduce the surface tension of the liquid sample, so that samples with relatively high viscosity will not form a film on the sample adding hole, thus causing poor chromatography.

[0033] The two protrusions 5 play a role in isolating the handheld part 3 and the observation window 2, preventing accidental contact with the sample adding area and causing sample contamination and operator hand contamination, thereby avoiding the situation of inability to test or incorrect results. The protrusions 5 include but are not limited to arc-shaped protrusions, serrated protrusions, wavy protrusions, trapezoidal protrusions, etc. The protrusions 5 include but are not limited to single-layer protrusions, multi-layer stepped protrusions, multi-layer gradually changing arc-shaped protrusions, etc. The height of the protrusions 5 is between 1 and 5 millimeters, and the width is not narrower than the width of the test strip, ensuring sufficient water-blocking area.

[0034] A plurality of positioning posts 7 and a plurality of positioning holes 8 are correspondingly provided on the inner side walls of the upper cover and the lower shell, and the positioning posts 7 are inserted and matched with the positioning holes 8. The positioning posts 7 are not all provided on the upper cover. The number and installation positions of the positioning posts 7 and the positioning holes 8 can be adjusted according to actual situations.

[0035] A clamping edge 9 is provided on the lower shell, and a clamping groove 10 is correspondingly provided on the upper cover. The clamping edge 9 and the clamping groove 10 are firmly connected to fix the upper cover and the lower shell, that is, the upper cover and the lower shell are integrally clamped through the clamping cooperation of the clamping groove 10 and the clamping edge 9.

[0036] During installation, first horizontally place the test strip into the installation groove of the lower shell, and then snap the upper cover onto the lower shell, thereby stably clamping the test strip. During testing, the staff takes the reagent card through the handheld part, and the reagent card separates the handheld part, the sample adding part, and the observation window part, which is convenient for operation and observation.

[0037] In this application, the handheld parts 3 are provided on the upper and lower sides of the upper cover, and a plurality of groups of anti-slip structures 4 are provided on the side and front of the handheld part 3, which can be pinched and held from above and below or from both sides, which is convenient for users with different habits and convenient for users to hold.

[0038] The shape of the sample adding hole 1 in this application is an irregular circle, which can reduce the surface tension of the liquid sample, so that samples with relatively high viscosity will not form a film on the sample adding hole 1, thus causing poor chromatography.

[0039] In this application, raised portions 5 are provided on both sides of the sample addition hole 1 near the hand-held portion 3 and the observation window 2 on the front of the upper cover, preventing accidental touch of the sample addition area and resulting in sample contamination and operator hand contamination. It can also prevent sample overflow to the hand-held portion and the observation window, causing contamination of the hand-held portion 3 and the observation window 2, resulting in inability to test or incorrect results. Thereby, it helps to improve convenience and enhance detection accuracy, making it more suitable for home use.
