Description

Technical Field

[0001] The utility model relates to the technical field of centralized dispensing of intravenous drugs, and particularly relates to a multi-station solvent residual liquid self-suction device for a static mixing center. Background Technique

[0002] The static mixing center of the hospital prepares thousands of groups of liquids every day. Among them, 400 groups of drugs are selected without using the whole bag of solvent. For example, the drug specification of ranitidine hydrochloride injection is 2ml, and the doctor's order generally selects 200ml of solvent. The common specification of the solvent is 250ml of 0.9%.
