Abstract

The invention relates to a micro-fluidic chip which is provided with a plurality of distribution reaction structures. Each distribution reaction structure comprises an A-zone sample adding hole, an A-zone distribution cavity and a reaction unit which are communicated in sequence. The reaction unit comprises an A-zone first micro-channel and a reaction chamber. And the reaction cavity is communicated with the A region distribution cavity through the A region first micro-channel. When the micro-fluidic chip is used for detection, sample liquid is added into the A-zone sample adding hole, enters the A-zone distribution cavity, then enters a plurality of reaction cavities in the corresponding distribution reaction structure from the A-zone distribution cavity through the A-zone first micro-channel, and is mixed and reacted with stored substances in the reaction cavities. The plurality of distribution reaction structures can detect a plurality of samples, in each distribution reaction structure, a plurality of reaction units are arranged, and the plurality of reaction units can detect a plurality of items, so that the plurality of samples can be subjected to multi-item detection on the same chip, and multi-sample and multi-item joint detection is realized.

Description

technical field

[0001] The invention relates to the field of microfluidic technology, in particular to a microfluidic chip. Background technique

[0002] Chemiluminescence immunoassay refers to the generation of photons by chemical reaction without excitation by external light source, heat or electric field. It can combine highly sensitive chemiluminescence detection technology with highly specific antigen-antibody immune reaction to detect the A technique for the antigen or antibody assay.

[0003] Point-of-care testing (POCT) refers to clinical testing and bedside testing performed next to the patient. It is usually analyzed immediately at the sampling site, eliminating the need for complex processing procedures during laboratory testing and quickly obtaining test results.

[0004] Microfluidic chip (microfluidic chip) is the current hot spot in the development of miniaturized total analysis systems, which can be applied to the instant detection of chemiluminescence immun...
