Description

Technical field:

However, there is usually a small amount of drug liquid left in the drug residue. If the drug residue is directly discharged, it is easy to cause waste of drug liquid. Therefore, in order to avoid waste of drug liquid, it is necessary to process the drug residue to facilitate the recovery of a small amount of drug liquid in the drug residue and avoid waste. This case is born out of this. Utility model content:
