Hospital Drug Based traceability system and method of tracing time window

Hospital drug traceability system and the present invention discloses a method of tracing based on time window, the system includes a data acquisition unit, the time window generating traceability internet terminal and medicines; data acquisition unit acquires from the hospital, the hospital inventory management system and hospital information management system of pharmaceutical flow information, and drug information collected for the corresponding batch processing, in patients, the drug and the time window information, and then outputs the data to the time window of the time window generation information platform, to generate and store drugs; drugs traced terminals by a person computer interface, and medicine kit traceability traceability module, the user issues an instruction through the retroactive interactive interface, i.e., the drug package module traced retrospectively from the toolbox tools according traced call instruction, while generating a time window from the platform call related data drugs; and tool kits of drug-related data are processed, and finally outputs the data processed to the terminal retroactive interactive interface, complete traceability during the drug.
