CPR Manikin Sensor Cluster for Objective Skill Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CPR training methods are costly, time-consuming, and lack objective assessment, with instructors required for feedback, and unsensorized manikins need upgrading for reliable sensor integration, while existing systems do not adequately motivate self-improvement beyond minimum skill levels.
Innovation Solution
A system comprising a sensor cluster with a distance sensor and pressure pad installed in a manikin for easy integration, providing objective feedback and competence level motivation through a computer program product for formative testing of CPR skills, allowing self-improvement and integration with existing manikins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional instructor-based CPR training is used, then trainees receive real-time feedback and guidance, but training becomes costly and time-consuming
Solution Approach 1:
The system enables self-assessment by providing automated feedback through sensors and a computer program. Trainees can independently perform CPR on the manikin and receive objective performance data without requiring an instructor's time and attention, thus eliminating the contradiction between assessment quality and resource consumption
Solution Approach 2:
The patent replaces the mechanical system of instructor observation and manual assessment with an automated sensor-based measurement system. The sensor cluster objectively measures CPR parameters and the computer program provides structured feedback, substituting human judgment with precise instrumental measurement
2Reliability
If instructor application with real-time feedback is used, then trainee performance is monitored, but it does not represent actual emergency situations where no feedback is available
Solution Approach 1:
The system provides preliminary guidance instructions before the trainee begins CPR performance. This allows trainees to understand the correct technique in advance and self-correct during the assessment period, making the no-feedback assessment period more reliable while maintaining ease of independent operation
Solution Approach 2:
The system implements delayed feedback by providing performance data after the assessment period rather than during it. This simulates real emergency conditions more accurately while still providing objective measurement, resolving the contradiction between assessment reliability and operational independence
3Measurement precision
If unsensorized manikins are used, then they are simple and inexpensive, but they cannot provide objective sensor data for skill assessment
Solution Approach 1:
The patent introduces a sensor cluster as an intermediary component that can be attached to or integrated with existing manikins. This intermediary layer provides the necessary measurement capabilities without requiring complete redesign of the manikin, thus achieving precise measurement while maintaining ease of manufacture through modular integration
4Loss of time
If frequent CPR assessments are implemented, then skill deterioration is detected early, but lack of personnel and time prevent regular assessments
Solution Approach 1:
By enabling self-assessment, the system eliminates the need for instructors to conduct and evaluate each CPR test. Trainees can independently complete assessments at any time, dramatically increasing assessment throughput while maintaining early detection of skill deterioration
Solution Approach 2:
The system enables periodic self-assessment at convenient intervals rather than requiring scheduled instructor-led sessions. This allows trainees to frequently monitor their skills over time without consuming institutional personnel resources, resolving the contradiction between detection speed and system capacity
