Defibrillator Automatic Activation Pattern Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing defibrillators often experience unnecessary battery depletion due to inadvertent automatic activation, caused by faulty sensors, overstuffing of accessories, or unobservable latch failures, leading to delayed therapy and increased costs.
Innovation Solution
A defibrillator with an improved automatic power-on feature that detects patterns of inadvertent activation and disables the automatic power-on function when such patterns are detected, re-enabling it only when the device is manually activated by a user, ensuring that routine maintenance does not trigger unnecessary power-ups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the automatic power-on feature is enabled to minimize response time, then the readiness for emergency use is improved, but the battery suffers unnecessary depletion due to inadvertent activation
Solution Approach 1:
The system monitors activation patterns and uses this feedback to dynamically adjust the automatic power-on behavior. When inadvertent activations are detected through pattern analysis, the system automatically disables the automatic power-on feature, thereby preventing unnecessary battery depletion while maintaining rapid response capability when needed.
2Productivity
If the automatic power-on feature is continuously enabled to ensure rapid response, then the productivity is improved, but the reliability deteriorates due to battery failure from unnecessary depletion
Solution Approach 1:
The automatic power-on feature transitions from a static always-enabled state to a dynamic state that adjusts based on detected activation patterns. The system automatically modifies its behavior in real-time, enabling rapid response when appropriate and disabling when inadvertent activation is detected, thereby maintaining both productivity and reliability.
3Ease of operation
If the automatic power-on sensor is highly sensitive to detect case opening, then the ease of operation is improved, but the measurement precision worsens due to false activation from overstuffing or latch failure
Solution Approach 1:
The system uses feedback from multiple activation events to refine its detection accuracy. By analyzing patterns across multiple cases, the system can distinguish between intentional case openings for use and inadvertent openings caused by overstuffing or latch failures, thereby improving measurement precision without sacrificing ease of operation.
Solution Approach 2:
The system performs preliminary analysis of activation patterns before making decisions about automatic power-on behavior. By evaluating historical activation data in advance, the system can identify inadvertent activation patterns and adjust its sensitivity accordingly, preventing false activations while maintaining responsive detection for legitimate use.

AI summary
A defibrillator (100) and method (300) are described having an improved automatic activation feature. The improvement comprises sensing a pattern of events which indicates that repeated activations are inadvertent, and thus are unnecessarily depleting the battery. The defibrillator then disables the automatic activation circuit (210) feature. Then, the sensing of a manual defibrillator operation may trigger a re-enablement of the automatic activation feature.
