Insulin Pump Pulse Delivery for Energy-Efficient Basal Dosing

The motor operates in pulsatile mode with periodic on/off cycles instead of continuous operation. The controller activates the motor for specific pulse durations at defined intervals, allowing the insulin pump to deliver insulin in controlled bursts while conserving energy during off periods, thus resolving the contradiction between energy consumption and maintaining delivery rate.

The motor position sensor serves dual purposes: it controls motor positioning and simultaneously detects occlusion conditions by monitoring motor current and position data. The system uses existing sensor data to identify occlusion events without requiring additional strain sensors, thereby improving detection accuracy while avoiding increased device complexity.

Instead of adding mechanical friction compensation mechanisms, the system uses software-based algorithms that process motor current and position data to calculate and compensate for friction effects. This computational approach achieves improved delivery precision without increasing mechanical complexity, as the compensation is performed through software processing of existing sensor data.
