Micro-fluidic chip, method for manufacturing same and method for applying micro-fluidic chip

Abstract

The invention provides a micro-fluidic chip which comprises a chip body, a plurality of liquid reagents with diversified specifications and packaging sheets. A plurality of test flow channels for testing to-be-tested samples are arranged on the chip body; the liquid reagents are accommodated in the corresponding test flow channels; the packaging sheets cover two sides of the chip body. The invention further provides a method for manufacturing the micro-fluidic chip and a method for applying the same. The micro-fluidic chip and the methods have the advantages that the liquid reagents with the diversified specifications are packaged in the chip body in advance, and accordingly accurate test results can be guaranteed; liquid reagent filling processes and double-side packaging processes are relatively mature, accordingly, the micro-fluidic chip is low in manufacturing cost and is favorable for automatic operation, and industrialization can be facilitated.

Description

technical field [0001] The invention belongs to the field of microfluidic technology, and more specifically relates to a microfluidic chip, its manufacturing method and usage method. Background technique [0002] POCT (point-of-care diagnostic equipment) refers to clinical testing equipment that does not require a fixed testing site and can be operated without specialized personnel. In Vitro Diagnostic is a system for analyzing and diagnosing human or animal body fluids (blood, urine, tissues, etc.) in vitro, which is composed of corresponding instruments and reagents. Generally, the reagents need to be integrated and pre-installed on the microfluidic chip before the detection. At present, most of the microfluidic chip reagents are packaged in the form of freeze-dried balls to realize the solid reagent packaging. The solid reagent is directly packaged in the reaction chamber. However, The manufacturing process of traditional freeze-dried reagents is complex, and the product...
