Abstract
A monitor camera (18) is arranged for monitoring an ID unit (42 of a medical staff. The ID of a staff who is opening a storage cabinet (12) is identified and authenticated by a management device (22). When the authentication is successful, a shelf (28) of the storage cabinet (12) is unlocked. An RFID reader (34) is arranged on the storage cabinet (12) so as to read an RF ID of an article in the shelf (28) when the shelf (28) is opened and closed and identify an article placed or removed according to the difference between the ID lists when the shelf is opened and closed. When a medical staff takes a medical product or medical instrument out of the storage cabinet, it is possible to automatically record who took out which medical product. Moreover, it is possible to prevent taking out of a medical product by an unauthorized person.
