Abstract

A medication dispenser provides automation to the steps of locating and acquiring medications to be administered to a patient. The medication dispenser includes an enclosure providing a secure environment for storing medications in multiple sized medication storage bins. The medication storage bins are hung in storage racks located within the enclosure. A robot system is also provided within the enclosure for moving bins between the storage racks and a medication dispensing area. The medication dispensing area includes doors configured to open to define an opening for passing a selected bin through the enclosure. The medication storage bin includes multiple sub-compartments, each configured to receive a single medically related item. The medication storage bin is moved through the opening to present the first sub-compartment containing a medically related item, while other sub-compartment containing medically related items remain within the enclosure.
