[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-Figure 3 A chromatography test card for multiple test liquids includes a test card body 1. The surface of the test card body 1 is provided with a dripping area 11 and a display area 12. A protective mechanism is installed on the surface of the test card body 1. The protective mechanism includes a baffle 2. The lower surface of the baffle 2 is fixedly connected and sealed to the upper surface of the test card body 1. The surface of the baffle 2 is provided with hollow grooves. The multiple hollow grooves are respectively aligned and adapted with the multiple dripping areas 11 and the display area 12. Both ends of the baffle 2 are fixedly connected with mounting seats 21, and the test card body 1 is located between the two mounting seats 21.

[0025] In order to provide auxiliary protection for the detection card body 1, a mounting groove is opened on the upper surface of the baffle 2, and the inner wall of the mounting groove is fixedly connected to an isolation airbag 22. Multiple hollow grooves are respectively located on the inner sides of multiple isolation airbags 22. The isolation airbags 22 are used to enclose the openings at the upper ends of the hollow grooves, thereby preventing the detection liquid from flowing out.

[0026] By installing a protective mechanism on the surface of the detection card body 1, the baffle 2 in the protective mechanism is combined with two mounting seats 21 to form a U shape, thereby wrapping the detection card body 1 for protection, and at the same time, an isolation air bag 22 is installed on the surface of the baffle 2, so that even when the baffle 2 is small in size, the isolation air bag 22 can assist in buffering protection, thereby making the protective mechanism convenient for protecting the detection card body 1 and reducing the chance of accidental damage such as squeezing.

[0027] In order to squeeze the extrusion airbag 27, a slide groove 23 is provided on the upper surface of the mounting seat 21, and the inner wall of the slide groove 23 is slidably connected with an extrusion plate 24. The upper surface of the extrusion plate 24 is provided with an anti-slip pattern 25. The anti-slip pattern 25 is provided on the upper surface of the extrusion plate 24, so as to facilitate the extrusion plate 24 to be moved. The inner side walls of both ends of the slide groove 23 are provided with a limiting groove, and both ends of the extrusion plate 24 are fixedly connected with a limiting strip 26. The surface of the limiting strip 26 is slidably connected to the inner wall of the limiting groove, and the extrusion plate 24 is used to squeeze the airbag 27. The limiting strip 26 slides in the slide groove 23, thereby facilitating the directional movement of the extrusion plate 24. An airbag groove is provided on the inner bottom wall of the slide groove 23. An extrusion airbag 27 is fixedly connected to the inner wall of the airbag groove. The upper end of the extrusion airbag 27 is located above the slide groove 23. The upper end of the extrusion airbag 27 is extended from the slide groove 23, thereby facilitating the extrusion plate 24 to extrude the upper end of the extrusion airbag 27. One end of the extrusion plate 24 is set to a smooth curved surface, thereby facilitating the extrusion plate 24 to slide toward the surface of the extrusion airbag 27.

[0028] A connecting tube 28 is fixedly connected to the lower end of the extrusion airbag 27, and the end of the connecting tube 28 is connected to the interior of the isolation airbag 22. The connecting tube 28 is used to connect the extrusion airbag 27 and the isolation airbag 22, thereby facilitating the flow of gas in the extrusion airbag 27 and the isolation airbag 22.

[0029] By installing an extrusion airbag 27 and an isolation airbag 22 on the surfaces of the mounting seat 21 and the baffle 2 respectively, the gas in the extrusion airbag 27 is discharged into the isolation airbag 22, so that the isolation airbag 22 expands and stands upright, thereby enclosing the upper end opening surface of the dripping area 11, thereby preventing the detection liquid from mixing into the dripping area 11 of the wrong object.

[0030] Working principle:

[0031] When storing, multiple test card bodies 1 are stacked, and between two adjacent test card bodies 1, the squeezing airbag 27 and the isolation airbag 22 support and buffer the upper layer pressure;

[0032] When in use, the extrusion plate 24 is pushed, and the extrusion plate 24 slides in the slide groove 23 through the limiting strip 26 and squeezes toward the surface of the extrusion airbag 27. The extrusion airbag 27 is squeezed and contracts, and the air in the extrusion airbag 27 enters the isolation airbag 22 through the connecting tube 28. The isolation airbag 22 expands and deforms, and the enclosure of the dripping area 11 is increased, and the excess test liquid dripped into the dripping area 11 cannot flow out.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
