A sliding closed pathogen detection cartridge

Abstract

The invention provides a sliding type closed pathogen detection card box comprising a transparent box body, wherein the box body consists of a front wall, a rear wall and an annular enclosure; both the front wall and the rear wall are respectively provided with a circle of grooves, and two ring openings of the annular enclosure are embedded into the grooves of the front wall and the rear wall in a matching mode; the annular enclosure consists of an inner-layer annular ring and an outer-layer annular ring; the inner-layer annular ring is made of a transparent hard material, and a long elliptical hole is formed in the top surface of the inner-layer annular ring; the outer-layer annular ring is an annular transparent sheet, a round hole is formed in the sheet corresponding to the long elliptical hole, and the annular transparent sheet can slip along the inner-layer annular ring; and a base which is fixed at the bottom of the inner-layer annular ring is arranged in a cavity, a plurality of uniformly-arranged reagent tanks are formed in the base, and all reagents required for a detection process are pre-fed in the reagent tanks. According to the sliding type closed pathogen detection card box provided by the invention, a disease detection process can be completed in a basically closed environment, and the sliding type closed pathogen detection card box is disposable, so that the cross contamination problems and the infection hazards of experimenters can be greatly reduced.

Description

technical field [0001] The invention relates to a detection cartridge, in particular to a sliding closed pathogen detection cartridge, which is suitable for a portable and automatic biochemical detection system and belongs to the fields of biology, analytical chemistry and medical detection. Background technique [0002] In the process of disease detection, it is first necessary to separate and purify the nucleic acid of the pathogen. The traditional nucleic acid separation technology has complicated steps, takes a long time, has low extraction efficiency, will come into contact with toxic reagents, and is carried out in an open environment, which is prone to pollution. The above-mentioned shortcomings can be well overcome by using the magnetic bead method nucleic acid extraction technology based on magnetic separation technology. The method does not need centrifugation, does not need to add various toxic reagents, is safe, non-toxic, fast and reliable, and is simple to oper...
