Description

Technical Field

[0001] The present invention relates to the technical field of rapid detection, and particularly relates to a flip-type detection kit that is pollution-proof and easy to chromatograph. Background Art

[0002] The immunochromatographic test strip is a rapid and convenient detection tool based on the specific binding of antigen and antibody. The immunochromatographic test strip generally consists of 5 parts: a base plate, a sample pad, a conjugate pad, a reaction pad, and a blotting paper. Its principle is that after the sample is dropped onto the sample pad, the sample moves under the action of capillary action and blotting paper. First, it passes through the conjugate pad carrying the coated colored nanoparticle antibody / antigen. If the sample contains a specific antigen / antibody, it binds to the antigen / antibody of the coated nanoparticles on the conjugate pad when passing through the conjugate pad, and then continues to move to the reaction pad and binds to the specific antigen / antibody on the corresponding reaction pad. At this time, the colored nanoparticles aggregate and develop color on the reaction pad, indicating the corresponding test result. Due to its convenience, rapidity, low price, and easy portability, the immunochromatographic test strip is widely used in various fields, especially for home self-testing.

[0003] Currently, the test kits used to load test strips on the market and in laboratories are usually of the inlay type. An inlay column is provided inside the test kit to connect the upper and lower shells. However, since the inlay columns of the upper and lower shells are very small, and the shells are also small, with a small stress area, it is very inconvenient to open and close the upper and lower shells. For example, the utility model patent CN2019220947036 discloses a multifunctional chromatographic test kit, in which the snap cover and the snap bottom are connected through the snap protrusions and snap depressions provided thereon. The installation process of this type of outer shell is troublesome, the inlay columns are easily damaged, it is not convenient for recycling, resulting in a waste of resources, and the occupied space of the separated upper and lower shells is also larger. At the same time, the accommodation area for the test strip inside the shell is also horizontally placed, and the chromatography is mainly through the blotting pad, which to a certain extent limits the chromatography speed. Moreover, after use, the test kit contains body fluid components such as blood, serum, urine, and saliva, which are prone to leakage and have a certain degree of danger. In order to achieve the purpose of saving resources, the outer shell of the test kit will be recycled. If the used test strip inside the test kit is to be removed during recycling, it becomes a problem because it is difficult to separate this inlay-type test kit.

[0004] In order to solve the above problems, the present utility model designs a flip-type detection kit that is pollution-proof and easy to chromatograph in line with the concept of convenience and low time consumption, improves the chromatography speed, prevents sample leakage and pollution, facilitates the user to open and close the lid and the bottom of the box, and reduces the workload of the operator.
