    摘要: An improved pump, reservoir and reservoir piston are provided for controlled delivery of fluids. A motor is operably coupled to a drive member, such as a drive screw, which is adapted to advance a plunger slide in response to operation of the motor. The plunger slide is removably coupled to the piston. Methods, systems, and articles of manufacture for automatically detecting an occlusion in a medication infusion pump are provided. The electrical current to an infusion pump may be measured. Based on measurements of one or more variables, and/or multiple measurements of a single variable, such as force, the infusion pump detects whether there is an occlusion in the system. The methods of detecting occlusions may be dynamic.
