Multi-index detection centrifugal micro-fluidic chip

Abstract

The invention discloses a multi-index detection centrifugal micro-fluidic chip, which comprises a cover plate layer, a passage layer and a bottom plate layer, wherein the cover plate layer and the bottom plate layer are respectively and correspondingly arranged at the top and the bottom of the passage layer and are in sealed matching with the passage layer; the cover plate layer is provided with avisual window, a sampling hole of liquid to be tested, a cleaning liquid sampling hole, a ventilating hole and a cover plate chip fixing hole; the bottom plate layer is provided with a chromatographytest paper strip and a bottom plate chip fixing hole; the chromatography test paper strip consists of a sample pad, a nitrocellulose membrane and an adsorption pad; the nitrocellulose membrane is positioned in the middle; the sample pad and the adsorption pad are positioned at two ends; the passage layer is provided with a detection region through hole, a pool of liquid to be tested, a passage ofliquid to be tested, a cleaning liquid pool, a cleaning liquid passage, a main passage, a marking reaction pool, a marking reaction liquid passage, a sampling pool, a waste liquid pool, a ventilationpassage and a passage chip fixing hole. The invention provides the multi-index detection centrifugal micro-fluidic chip with the advantages of clean and sanitary effects, detection precision and highautomation degree.

Description

technical field [0001] The invention relates to the technical field of microfluidic chip detection, and more specifically relates to a multi-index detection centrifugal microfluidic chip. Background technique [0002] Microfluidic chip is an emerging technology for manipulating and detecting chemical or biological samples on a chip. The microfluidic chip can integrate the operation units of sample preparation, reaction, separation and detection into a chip of several square centimeters, and automatically complete the analysis process by manipulating and controlling the fluid in the microchannel network. Because microfluidic chip technology has the characteristics of small injection volume, high integration, easy automatic control and high-throughput analysis, the biochemical reaction operation on the microfluidic chip is more convenient and faster than conventional analysis sample pretreatment. ,low cost. [0003] Chromatographic test strips have been widely used in clinic...

AI Technical Summary

Problems solved by technology

In routine operation, the operator needs to manually add the cleaning solution after adding the test solution and waiting for a period of time, and then use visual or simple detection device to read the result. The degree of automation is poor, which affects the detection efficiency.
