Abstract

A medication dispensing cart (10) having a computer and monitor (12), a work surface (16) with pull out keyboard (18), and plural drawers (30) arranged as a vertical series of cassettes that can be added as needed. The battery powered device uses software and pass codes for controlling access to each drawer, and requires a second pass code for any drawer designated to contain narcotics. Records can be kept of who dispenses what medication and when for each cart in a system of carts. The cart in the system is in wireless communication with a system administrator. Emails alerting the system administrator of low battery power, of a cart switching to off, of an attempted break-in, and of inventory and usage data are sent automatically by email.
