Abstract

See full text

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, such as force, the infusion pump detects whether there is an occlusion in the system. The methods of detecting occlusions may be dynamic.
