Portable medication dispensing unit
A medication dispensing cart has a pull-out drawer, and a conveyor that transports a number of removable medication bins within the cart, one at a time, to the position of the drawer. An on-board processor controls operation of the bin conveyor mechanism whose pathway can be a serpentine (folded) loop. The drawer slide engages the bin located at the drawer position, and the bin can be pulled forward from said conveyor and pushed back onto the conveyor. The bins can be lifted out when the drawer is opened. A 2-D bar code symbol or other machine-readable code, positioned on the bin, contains data identifying the contents of the bin and the associated patient. A reader device reads the coded symbol and transfers data for that bin to an on-board processor. The processor keeps track of the bins on the conveyor, as well as their contents. Pusher arms on the drawer assist in pushing the bin out when the drawer is opened and in returning the bin onto its carrier when the drawer is closed. The arms are rocked out of contact with the associated bin when the drawer is in a fully closed position. The processor provides a record for accountability of access to the bins. An alternative arrangement can be seven feet in height with the drawer access at waist level, and with a pull-out work shelf.
