The invention relates to a liquid path control device based on PCR. The device comprises a motor pump and a liquid path valve. The motor pump is connected with a liquid inlet on a pipeline layer, and the motor pump and the liquid path valve are matched to control the flow direction of liquid in the pipeline layer; the motor pump comprises a motor set and a connecting shaft, an output shaft of the motor set is fixedly connected with the connecting shaft, the liquid path valve comprises a first motor and a valve head, and the first motor rotates to drive the valve head to downwards generate pressure on a pipeline layer, so that liquid in a pipeline is intercepted; when the valve head faces downwards or upwards, the motor set drives the connecting shaft to push in or suck out liquid in the pipeline layer. Through cooperation of the motor pump and the liquid path valve, injection of a reagent is achieved, reaction and transfer of nucleic acid substances in the pipeline layer are achieved through cooperation of the motor pump and the liquid path valve, corresponding operation is carried out in the purification bin or the amplification bin, continuity of an experiment is achieved, and the progress and flow of the experiment are controlled through cooperation of the motor pump and the liquid path valve. The device is simple, convenient and easy to implement.
Description
technical field [0001] The invention relates to the field of biological detection, in particular to a liquid circuit control device based on PCR. Background technique [0002] In scientific experiments such as biology, chemistry, and materials, it is often necessary to operate on fluids, such as the preparation of sample DNA, liquid chromatography, PCR reaction, and electrophoresis detection, all of which are performed in a liquid-phase environment. If the steps of sample preparation, biochemical reaction, and result detection are to be integrated on the biochip, the amount of fluid used in the experiment will be reduced from milliliters and microliters to nanoliters or picoliters. At this time, powerful microfluidic devices are necessary. Indispensable. Therefore, with the development of biochip technology, microfluidic technology, as a key supporting technology of biochip, has also received more and more attention. [0003] The purification and recovery of nucleic acid i...
