The invention includes a medicine cabinet department, a medicine inventory information department, a medicine importance classification information department and a central display department.The medicine cabinet department is used to contain and access a plurality of drugs. The medicine inventory information department corresponds to a plurality of drugs, and has a plurality of drug information.The drug importance classification information department classifies the complex drug information into three weighting coefficients, which correspond to one of the built-in complex percentage ranges.When each drug is used, the drug inventory information department will retrieve the drug information and display it with the light information. At the same time, it will send it to the drug importance classification information department for its cooperation with the weighting coefficient calculation. Finally, it will display the corresponding interval light information in the central display department.Therefore, this case has the advantages of clearly controlling the inventory status of all drug cabinets and making the inventory warning more sensitive through different drug importance classifications.本發明係包括一藥櫃部、一藥品庫存資訊部、一藥品重要性分類資訊部及一中央顯示部。藥櫃部用以容納、取用複數種藥品，藥品庫存資訊部對應複數種藥品，而具有複數藥品資訊。藥品重要性分類資訊部將複數藥品資訊分類而分別對應三個加權係數，其分別再對應內建的複數百分比區間其中一者。藥品庫存資訊部在每一藥品被取用時，擷取其藥品資訊進而以燈號資訊顯示，同時傳送至藥品重要性分類資訊部，供其配合加權係數運算，最後於中央顯示部呈現對應之區間燈號資訊。故，本案達到兼具可清楚掌控全部藥櫃部之庫存現況，及透過不同之藥品重要性分類使庫存之預警更靈敏等優點。
