TLDR
In this article, a method, system, and article of manufacture for automatically detecting an occlusion in a medication infusion pump is provided. Butts et al. measured the electrical current to an infusion pump and used it to detect whether there are occlusions in the system.Abstract:
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. A method, system, and an article of manufacture for automatically detecting an occlusion in a medication infusion pump is provided. The electrical current to an infusion pump is measured. Based on measurements of one or more variables, the infusion pump detects whether there is an occlusion in the system. The methods of detecting occlusions may be dynamic.read more
