Heart Defibrillators TRIZ Cases
- Touch Screen User Interface for Monitor Defibrillator ECG Review
A monitor defibrillator uses a touch screen interface to enable intuitive scrolling and zooming of electrocardiogram waveforms.
- Defibrillator Power Management via Clinical Activity Detection
Clinical activity detection modules trigger automatic power status changes to reduce battery depletion risks from manual user errors.
- Implantable Cardiac Device Tachycardia Discrimination
Dual vector interval analysis discriminates ventricular tachycardia from fibrillation, reducing unnecessary shocks and preserving battery life.
- Subcutaneous Defibrillator Low Energy Cardioversion
Low energy cardioversion converts ventricular tachycardia in subcutaneous defibrillators, extending battery life and improving patient comfort.
- Wireless Cardiac Pulsatility Sensing for ICD Shock Reduction
Distinct electrode dipoles measure transimpedance changes from cardiac pulsatility, reducing unnecessary shocks by verifying ventricular activity.
- Battery-less Piezo-electric Defibrillator for Emergency Portability
Piezo-electric generators convert manual compression energy into defibrillation pulses, eliminating heavy batteries and enabling portable emergency use.
- Dual-Threshold QRS Detection for Wearable Arrhythmia Therapy
A wearable medical system uses dual detection thresholds to differentiate tachyarrhythmia and bradyarrhythmia signals.
- MR-Compatible Defibrillator Using Piezoelectric Transformer
A piezoelectric transformer charges a storage element in an MR-compatible defibrillator.
- Shape Memory Implant Self-Expanding End Parts
A shape memory implant transitions from a compact form to an expanded structure using self-expanding end parts.
- AED Notifier Alternating Light and Sound Modes
Alternating high and low intensity light and sound pulses in the AED notifier reduces instantaneous battery load while maintaining effective user notification.
- CPR Compression Monitor With Adaptive Release Velocity Feedback
Dynamic release velocity thresholds adapt to measured chest depth and rate, resolving fixed threshold limitations in CPR monitoring.
