Abstract: A stand-alone drug dispensing system suitable for a nursing station at a health care facility is described. A microprocessor controlled secure system makes it particularly suitable for dispensing narcotics and other controlled substances. The system comprises a cylinder having a plurality of stacked carrousels, each having plurality of drug slots. Each carousel holds a different drug and it is the rotation of these carrousels over a hole or chute that runs the entire length of the cylinder that allows the dispensing of a particular drug under the control of a programmed microprocessor. The system provides accurate accounting as well as advisory information about the drug being dispensed. A plurality of peripherals such as a Video Display Terminal, an alphanumeric printer, and an alphanumeric keyboard are integrated into the system. Also included are an alarm system, a back up power source and a slot for returning unused drugs.
