Micro-fluidic chip detecting reaction device with reagent storage function

Abstract

Provided is a micro-fluidic chip detecting reaction device with a reagent storage function. The detecting reaction device comprises a micro-fluidic chip and a driving device; long-term storage, fast release, reagent driving and detecting reacting of a dry reaction reagent and a wet reaction reagent are achieved through cooperation of the micro-fluidic chip and the driving device, and finally POCT type on-site fast detection is achieved. The micro-fluidic chip comprises a reagent storage module and a detecting reaction module; the reagent storage module comprises a cover plate, a storage structure plate and a connecting structure plate; the detecting reaction module comprises a reactor; before detection, half of the reactor is embedded into a groove of a chip locating base, then the reagent storage module is placed on a chip butt joint base, and the reagent storage module is moved under guidance of a square guide rail to be in fast butt joint with the detecting reaction module. Thus, the two modules of the chip are fast assembled, and the micro-fluidic chip and the driving device are mutually positioned and fixed.

Description

Technical field [0001] The invention relates to the field of life medicine detection and diagnosis, in particular to a microfluidic chip reaction device with a reagent storage function. Background technique [0002] In traditional detection methods, the instrument and the reagent are often separated from each other. Some reagents can be stored at room temperature, and some need to be stored in a low-temperature environment. During detection, the reagents need to be manually added to the detection instrument. Its shortcomings include: reagents need to be independent or even a special storage environment, which limits the scope of application of the detection device; reagents and instruments are separated from each other, requiring the inspector to complete a series of manual operations, which increases the complexity and errors of the detection process Probability, detection efficiency is low; the instrument structure is more complicated, and there are many auxiliary devices, the ...
