Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a droplet detection system, a droplet control device and a droplet detection method. Background technique [0002] With the development of biomedical technology, many biomedical applications rely on high-throughput assays of samples bound to reagents. This high-throughput detection requirement can be met by droplet detection technology. At present, the traditional droplet detection technology is to clamp the detection chip by a clamp, and the infusion tube is connected to the clamp, and the sample to be tested is sent to the detection chip in the form of a droplet through the infusion tube for detection. However, when the infusion tube is connected to the clamp, a rubber pad is added between the clamp and the infusion tube, that is, the infusion tube passes through the rubber pad and extends into the clamp. At this time, the rubber pad will generate elastic force under the i...

Problems solved by technology

However, when the infusion tube is connected to the clamp, a rubber pad is added between the clamp and the infusion tube, that is, the infusion tube passes through the rubber pad and extends into the clamp. At this time, the rubber pad will generate elastic force under the interaction between the infusion tube and the clamp. As a result, the infusion tube is prone to displacement under the action of the elastic force (for example: the infusion tube directly pops out of the clamp under the action of the elastic force), causing the sample to leak during the process of being introduced into the clamp with the infusion tube, reducing the detection effect on the sample
