Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.

The utility model relates to a device convenient for preserving and detecting a swab treatment solution, which comprises a base 1, a first container 2, a second container 3 and detection test paper 4;

the first container 2 and the second container 3 are arranged on the base 1 side by side, and the bottoms of the first container and the second container are communicated through a pipeline 5;

a first containing cavity 221 is arranged in the first container 2, the upper end and the lower end of the first containing cavity 221 are sealed by aluminum foil paper 6, and lysis solution 7 is contained in the first containing cavity 221;

a second cavity 31 is arranged in the second container 3, and the test paper 4 is placed in the second cavity 31 and can be observed by a user.

Referring to FIG. 1, a specific embodiment of the present invention is shown.

The test paper 44 is selected according to the pathogen to be detected. The test paper 44 comprises glass fiber containing a chromogenic tracer marker, a nitrocellulose membrane and filter paper which are sequentially lapped and stuck on a PVC rubber plate, wherein: the glass fiber containing the chromogenic tracer marker contains the chromogenic tracer, protein, salt ions, a surfactant, sugar molecules and a preservative; the nitrocellulose membrane is fixed with protein, salt ions and sugar molecules.

The detection principle of the detection test paper 44 is as follows: according to the method, an immunological reaction is used as a basis, a specific antibody of a target to be detected is marked on a chromogenic tracer, another specific antibody is coated on a nitrocellulose membrane, and finally, a macroscopic chromogenic strip is formed on the nitrocellulose membrane after the target to be detected in a swab is combined with the antibody marked on the chromogenic tracer and the antibody coated on the nitrocellulose membrane in sequence through the specific combination property of the antigen and the antibody, and then, the negative and positive of a detection result can be judged according to the existence of the chromogenic strip.
