WS/T433 and 2013, the technical operating Specification for intravenous therapy nursing, published in China also define that aseptic technology must be strictly executed in the process of drug configuration and infusion. The dissolution and preparation of the infusion drugs are carried out by nurses in unclean environments in the ward, so that the problems of drug pollution, physical damage caused by long-term inhalation of operators and the like are difficult to avoid. In recent years, some large hospitals with better conditions have set Intravenous drug administration centers (PIVAS), Intravenous drugs which are originally distributed in an open environment of a treatment room in a ward are administrated, and professional technicians are concentrated to carry out drug allocation in a ten-thousand clean and relatively closed positive pressure environment, so that the safety in the drug allocation process is guaranteed. However, the existing PIVAS has high manufacturing cost and high operation cost, so most hospitals in China still do not configure the PIVAS at present, and the infusion drug configuration link still cannot meet the aseptic technical requirement. Therefore, the invention provides a miniaturized clean transfusion preparation system for providing local positive pressure, which creates a sterile environment for providing the local positive pressure in the links of puncture suction and medicine dissolving when a transfusion medicine is prepared in the environment of a common ward, and meets the clinical requirement.
