Abstract
A blister pack for a inhalant medicator has a plurality of medical powder storage chambers spaced apart from each other in a circumferential direction. The inhalant medicator includes a pricking tool with a pair of parallel pins that prick inflow and outflow holes in one of the medical powder storage chambers during a preliminary operation of inhalant medication. The inflow and outflow holes are spaced apart from each other by a predetermined distance in a direction parallel to a lid panel of the blister pack to produce turbulent airflow within the medical powder storage chamber during inhalation during which the medical powder is inhaled by a patient's breathing. The medical powder storage chambers are dimensioned and designed to properly regulate or control properties of the airflow passing through the medical storage chamber, to ensure the airflow is suitable for the medical powder storage chamber.
