Construction of Dispensing System for Injectable Drugs

Traials and Evaluation of Automatic Dispensing Machine for Injectable Drugs

Abstract

We developed an automated injection dispensing machine to minimize pharmacist's involvement in the dispensing of injections, and evaluated its performance. The machine was constructed of four units: tray stocker unit, main unit in which the ampules and vials for each patient are automatically dropped into trays and the patient's name is labeled on the tray, the stock unit of dispensed trays, and the verification unit. The machine was evaluated by measuring the speed and the number of problem arising with each unit.
The time necessary to prepare each unit was 50-90 seconds and to set up each tray was about 90 seconds. During use in experiment (300-800 per unit), we encountered no problem. We considered the automated injection dispensing machine to offer new opportunities for clinical involvement by pharmacists.
