Methods, apparatuses, and uses for infusion pump fluid pressure and force detection

An occlusion detection system for detecting an occlusion in an infusion pump for infusing fluid into a body of a user, the occlusion detection system comprising:

• obtaining means for obtaining a measurement from a sensor before each fluid delivery;
• calculating means for calculating a slope of a line using two or more measurements, wherein the two or more measurements are not consecutive;
• comparing means for comparing the slope to a slope threshold;
• incrementing means for incrementing a slope counter when the slope exceeds the slope threshold;
• and
• declaring means for declaring an occlusion when the slope counter exceeds a slope detection count.

An occlusion detection system for detecting an occlusion in an infusion pump with a reservoir containing fluid for infusing the fluid into a body of a user, the occlusion detection system comprising:

• a housing;
• a motor contained within the housing;
• one or more drive train components that react to stimulus from the motor to force the fluid from the reservoir into the body of the user;
• a sensor that is positioned to measure a parameter associated with the motor or at least one of the drive train components;
• and
• an electronics system that obtains a measurement from the sensor before each fluid delivery, calculates a slope of a line using two or more measurements wherein the two or more measurements are not consecutive, compares the slope to a slope threshold, increments a slope counter when the slope exceeds the slope threshold, and declares an occlusion when the slope counter exceeds a slope detection count.
