CPR Mannequin Sensor Feedback for Training Accuracy

The patent incorporates sensors (accelerometer, gyroscope, magnetometer) that detect chest compression parameters and provide real-time feedback to the user through a display device. This feedback mechanism allows users to see whether their CPR performance meets the required criteria, resolving the information loss problem while maintaining the ability to perform repeated training exercises on the mannequin.

The patent replaces manual evaluation methods with an automated sensor-based measurement system. Instead of relying on human instructors to manually assess CPR performance, the system uses electronic sensors to objectively measure compression depth, rate, and position, then displays this information to the user, enabling self-evaluation and improving feedback effectiveness.

The patent uses a mannequin that replicates the essential anatomical features of a human body (chest, abdomen, airway) to serve as a training target. The mannequin includes sensors embedded in its chest area that detect compression parameters, allowing users to practice repeatedly on the same model while receiving real-time feedback similar to what would be obtained from training on a human body.

The patent introduces an intermediary evaluation system consisting of sensors and a display device that mediates between the user's CPR actions and the performance assessment. This intermediary system automatically measures compression parameters and provides real-time feedback, enabling users to train repeatedly on the mannequin while maintaining the feedback capability that would otherwise require human evaluation.

The patent combines multiple sensors (accelerometer, gyroscope, magnetometer) into an integrated measurement system that works together to comprehensively evaluate CPR performance. Rather than treating each sensor independently, the system merges their data to calculate overall performance metrics, reducing the practical complexity while maintaining high measurement precision through synergistic operation of the sensor array.

The patent designs the sensor system to serve multiple functions: measuring compression depth, compression rate, and compression position simultaneously using the same sensor array. This multi-functionality reduces the need for separate dedicated sensors for each parameter, thereby reducing overall device complexity while maintaining comprehensive measurement capabilities.
