Abstract

The invention provides a heating device of a micro-fluidic chip. The heating device comprises a heating body which is separated for a predetermined distance from a heating area of themicro-fluidic chip and a focusing device which is used for focusing heat emitted by the heating body to the heating area. On the basis, the invention further provides a heating, temperature detection and optical detection device and method for the micro-fluidic chip and a micro-fluidic chip system. According to the invention, the problems of cross contamination and chip structure damage of the micro-fluidic chip during heating are solved.

Description

technical field [0001] The invention relates to the technical field of microfluidic chips. More specifically, the present invention relates to a microfluidic chip heating, temperature detection and optical detection device and method and a microfluidic chip system. Background technique [0002] Because the reaction process of in vitro diagnostic reagents usually requires relatively high temperature, and its reactivity is the strongest in a suitable temperature range, so the quality of temperature control directly affects the detection results. The temperature control scheme used by traditional inspection equipment in the reagent reaction process is mainly a constant temperature bag. This solution mainly adopts resistance heating, semiconductor heating, etc., and has the characteristics or shortcomings such as large and bulky, high power consumption, high cost, long time required to reach a constant temperature range, and high failure rate. There are also some devices that ...
