Micro flow control chip used for multi-index biochemical detection

Abstract

The invention discloses a micro flow control chip used for multi-index biochemical detection. The micro flow control chip comprises a micro-fluid channel, a plurality of reaction tanks and a pneumatic micro-valve, wherein one opening end of the micro-fluid channel is a sample inlet while the other opening end is communicated with a chamber arranged in the micro flow control chip; the top wall of the chamber is an elastic film and is exposed in air; reaction tanks are connected in series or in parallel through the micro-fluid channel; the pneumatic micro-valve comprises a control channel; one sidewall of the control channel is an elastic film; and the control channel and the micro-fluid channel are arranged crossly. The micro flow control chip used for multi-index biochemical detection integrates sample introduction with multi-index biochemical reaction based on a micro flow control chip technical platform, so that the micro flow control chip used for multi-index biochemical detection, disclosed by the invention, has the advantages of greatly simplifying operating process, reducing consumption of samples and reagents, having no need to allocate expensive instruments, greatly reducing use cost, making on-site instant detection possible and having great foreseeable economic value and social value.

Description

Technical field [0001] The invention relates to a microfluidic chip for multi-index biochemical detection, and relates to the technical field of microfluidic chips. Background technique [0002] Biochemical analysis methods determine the concentration of trace components contained in blood or other body fluids, and provide doctors with a basis for clinical diagnosis, which is closely related to people's health and safety. In the process of analysis and detection of complex biochemical samples, due to the nature of certain target analytes or the limitations of the detector, ideal signals cannot be obtained through direct detection. In order to achieve the purpose of detection, it is an extremely common processing method to transform it into a strong signal substance matching the sensor or detector through a biochemical reaction. At present, conventional biochemical analyzers are based on the detection principle of spectrophotometry, and carry out enzymatic or immune reaction kine...

AI Technical Summary

Problems solved by technology

Although the existing semi-automatic or fully automatic biochemical analyzers have been widely used by medical testing institutions, these instrument systems are often bulky, expensive, complicated to operate, and slow in testing speed, so it is impossible to carry out real-time and rapid on-site instant testing

In addition, the matching biochemical reaction kits are also expensive and complicated to operate
