Abstract

A device is provided for controlling access to medical items. At least one ratcheting drawer is provided having a plurality of bins adapted to hold the medical items and disposed to become exposed sequentially as the drawer is opened. A latching mechanism engages the ratcheting drawer to prevent the drawer from opening. A sensor detects the position of the drawer relative to the bins and, when access to the contents of a particular bin is authorized, the latching mechanism disengages until the specific bin is exposed, as determined by the sensor.
