FIG. 3 is a schematic diagram for explaining the sequence flow of FIG. 2. In the take-out permission stage (1), a take-out executor (for example, a doctor or a nurse) of the medicine receives a take-out permission of the medicine. That is, the name of the permitted exporter and the permission conditions are written in the exporter RF tag 2 attached to the wristband of the exporter. Although not shown, at this stage, the permitted take-out person name and the permission condition are also written to the medicine setting RF tag 32 via the LAN 100 and the storage box setting reader / writer 33.
[0017]
Next, in the drug take-out stage (2), when taking out the medicine 31 stored in the medicine storage shelf 34 in the storage box 30, the name of the authorized exporter and the name of the authorized exporter are acquired from the medicine installation RF tag 32 attached to the medicine 31. The permission conditions are read and collated with the carry-out RF tag 2 carried by the person who received the advance permission, and only the person who received the advance permission can bring it out by matching and the person who has not received the advance permission takes it out In such a case, the alarm 50 sounds an alarm. If it is ignored and taken out, emergency information is sent to the monitoring terminal 60 where the observer is resident, and the search by the observer or the like is started. Further, in the step (3) of confirming the route of taking out the medicine, the movement route of the medicine 31 taken out via the plurality of readers / writers 80 installed in the hospital is confirmed one by one.
