Background technique

Drugs are special commodities related to people's lives and health, and the usage and dosage of drugs are an important part of drug use. It is necessary to effectively control the properties, authenticity, uniformity, purity, safety and content of active ingredients of drugs. Detecting drug concentrations in the body can be used to study the possibility of toxicity due to drug metabolism and guide more rational clinical use of drugs.

The prior art patent document with publication number CN217605362U provides a sampling device for targeted drug detection. The device rotates and pulls the handle upward, and the telescopic rod is extended so that the partition and the first sealing ring are along the edge of the sampling tube. The inner wall moves upward, and the external atmospheric pressure presses the targeted drug into the space. At the same time, the handle is turned to drive the spiral conveyor rod and the telescopic rod to rotate together. Turn the handle clockwise and then counterclockwise, and the targeted drug will move up and down inside the space. Compared with the existing technology, this device has a compact and flexible structure and low production cost. It can complete a homogeneous operation while sampling targeted drugs, thereby improving the efficiency and accuracy of targeted drug detection.

Although the above-mentioned existing technical solution can realize the homogeneous operation of sampling targeted drugs by rotating the screw conveyor rod and the telescopic rod together, it still has the following defects; when sampling, accurate sampling is required to ensure detection. accuracy, while the device will have slight deviations in actual manual sampling.

In view of this, we propose a sampling device for drug detection instruments.
