摘要：
The present invention relates to a method and related apparatus for rotating a piston of a drug pump during the pumping stroke to reduce drug pump wear. The actuator may move a piston that pumps fluid through a pumping channel. In the present invention, the armature includes one or more openings or shapes that cause the actuator, including the armature and the piston, to rotate about a longitudinal axis of the piston during the pumping stroke. Rotation of the actuator member may help to reduce wear to the actuator member and the pump itself caused by repetitive pumping motions.
