Abstract

The invention provides methods and apparatus for dispensing items from a dispensing unit. According to the invention, the dispensing unit comprises a plurality of locations in which the items are held, a processor in which records corresponding to the items on the unit are stored, and a plurality of item switches corresponding to the locations in which the items are held. The item switches are connected to the processor so that a user of the dispensing unit can input records of items removed from the unit into the processor. The apparatus described is particularly suited for dispensing medical supplies although the apparatus will be usable for other types of items as well. Preferred embodiments will include a plurality of visual indicators, typically in the form of light emitting diodes, corresponding to the locations in which the items are held. Upon selection of a desired item from a list of items held by the unit, the visual indicator corresponding to the item is actuated so that the user can locate the desired item quickly and conveniently with the help of the visual indicator.

Claims

1. A method for dispensing items from a dispensing unit holding the items, the method comprising:

providing a dispensing unit having a lockable door, a plurality of storage locations located within the dispensing unit and behind the same lockable door so that access to the plurality of storage locations is prevented when the door is locked and closed, and at least one item switch located adjacent to each storage location;

entering information into a processor associated with the dispensing unit, wherein the information includes at least user identification information and wherein the door is unlocked in response to entry of such information;

entering patient identification information into said processor;

opening the door to allow access to the plurality of storage locations;

removing one or more items from one or more storage locations after the door has been unlocked and opened;

manually touching an item switch located adjacent to the storage location from which the item was removed once for each individual item taken;

storing a record of removal for said item with said processor in response to said manually touching said item switch along with said patient identification information that is associated with said item.

2. A method as in claim 1, wherein the processor is located on the dispensing unit.

3. A method as in claim 1, further comprising entering other account identifying information into the processor.

4. A method as in claim 3, wherein both user identification and patient identification must be entered in order to unlock the door.

5. A method as in claim 4, wherein the processor communicates inventory information with a central computer system.

6. A method as in claim 1, wherein the processor totalizes the inventory of items in the storage location each time an item switch is manually touched.
