Study of Inspection System for Prevention of Dispensing Errors

Because of dependence upon human senses, conventional inspection of dispensing is not successful to find errors, especially in dispensing powder. Some studies to compare conventional inspection with computerized one, whose specification was described in the first paper, found the latter more effective in prevention of dispensing errors exactly.The result is as follows. In conventional inspection, it was difficult to check dispensing error since supplying powder preparations to the shelf bottles is made uniformly, and some of dispensing errors are sometimes passed over, which contains failure to select the shelf bottle, to weigh the powder and to check the maximal dose and incompatibility.This comparison showed many advantages of computerized inspection system. Using a computer made it possible to supply the powder preparations precisely. By utilizing console CRT or hard copy checking prescription, it was possible to prevent various dispensing errors. These data suggest that application of computerized inspection system makes it possible to dispense the powder more precisely than conventional way.
