Example Embodiment
[0028] The present invention follows the principle of separating the sample carrying part and the process control part as much as possible, and the former is made into the form of a cassette on which the nucleic acid extraction unit, acid amplification unit and nucleic acid detection unit used for nucleic acid analysis are integrated. Each unit is connected by micro-machined fluid pipelines, and the entire analysis process is controlled through an external control system independent of the cartridge. The control system includes at least a pump that can be started and stopped, a valve that can be turned on and off, and a detector for detecting the fluid position. They constitute a feedback system that can manipulate the movement of the fluid sample on the cartridge. Among them, choosing a pump that can be started and stopped, rather than a constant pressure gas source, as the driving force of fluid movement, can easily obtain and remove the pressure difference required to push the ...
