Description

Technical Field

[0001] The present invention relates to the technical field of micro-pharmaceutical sampling devices, and in particular to a micro-pharmaceutical sampling device for pharmaceutical management. Background Art

[0002] In pharmaceutical management, sampling of trace drugs is a crucial link. Due to the small amount of drugs, the accuracy and precision of sampling directly affect the subsequent drug analysis and use. Traditional sampling methods such as syringe sampling, due to the large size of the syringe, directly pulling the piston, the amount of drug sample sucked is not easy to control. And after being sucked, it is stored in a container. During the transfer process, the drug liquid hangs on the wall, which further affects the accuracy. When taking trace drugs, the error has a greater impact; if it is stored directly through a syringe, the piston is easily accidentally touched, causing part of the drug liquid to be discharged, which needs to be improved.
