AI Technical Summary

Technical Problem

Existing nucleic acid test kits are large and easily contaminated, complex to operate, difficult to achieve fully enclosed testing, and the test results cannot be released immediately, making it difficult to promote them widely at the grassroots level.

Method used

A nucleic acid detection cartridge was designed, comprising a cartridge body, a reaction tube, a control valve, and a pipetting actuator. Through the cooperation of the control valve and the pipetting actuator, the flow channel can be changed and the liquid can be transferred and mixed, ensuring a fully enclosed state, simplifying the structure and achieving miniaturization.

Benefits of technology

This technology enables the miniaturization and fully enclosed testing of nucleic acid test kits, avoiding internal contamination, improving testing efficiency and accuracy, and simplifying the operation process.

Abstract

The invention provides a nucleic acid detection card box and a nucleic acid detection method. The nucleic acid detection card box comprises a sample cavity, a pipetting cavity and a reagent cavity which are arranged at intervals along the box length direction of a box body, the reaction tube is provided with a reaction cavity; the control valve is accommodated in the valve body cavity and is provided with a plurality of mutually independent pipetting runners, and the pipetting runners are used for communicating one of the sample cavity, the reagent cavity and the reaction cavity with the pipetting cavity; the pipetting driving part is arranged in the pipetting cavity and can ascend and descend in the pipetting cavity, so that positive pressure or negative pressure is formed in the pipetting cavity. A plurality of pipetting runners are integrated on the control valve, so that the nucleic acid detection structure is simplified, other runner structures are not needed, the runners can be changed only by driving the control valve to rotate, the miniaturization of the nucleic acid detection card box is realized, and liquid transfer and mixing are realized in cooperation with lifting of the pipetting driving part; the nucleic acid detection card box can be always kept in a totally-closed detection state in a pipetting and uniform mixing process.
