Abstract

A storage device (100′) is provided for controlling access to medical items. The storage device (100′) has a drawer (104′) with a plurality of rows (115′), and a cover (200′) over each row (115′) of the drawer (104′) to secure the medical items in the bins (116′) located in the individual rows (115′) of the drawer (104′). The storage device (104′) has an unlocking member (208′) that is moveable between a first position and a second position to engage a specific cover (200′) of the drawer (104′) and thereby allow one of the covers (200′) to be opened when the drawer (104′) is opened. A sensor (130′) detects the position of the drawer (104′) and, when access to the contents of a particular bin (116′) is authorized, a control mechanism (117′) disengages until the specific bin (116′) is exposed, as determined by the sensor (130′).
