METHODS AND APPARATUS FOR DISPENSING SOLID PHARMACEUTICAL ARTICLES

摘要

An apparatus for dispensing solid pharmaceutical articles includes a housing, a flow generator and a sensor. The housing defines a dispensing passage. The flow generator is operable to generate a first flow of gas to force the articles along a first path through the dispensing passage. The sensor is positioned to detect articles passing through the dispensing passage. A port is defined in the housing adjacent the sensor and configured to direct a second flow of gas along a second path to agitate dust adjacent the sensor and thereby remove dust from the sensor and/or prevent dust from depositing on the sensor.
