Heart Defibrillators TRIZ Cases

A cartridge memory stores usage status so an AED can verify readiness and display whether electrode pads are unused before treatment.

Ventricular signals enable atrial arrhythmia detection during pacing.

This responder network queries nearby functional AEDs and trained volunteers, enabling dynamic deployment during cardiac incidents.

A voltage analyzer switches from the main battery to a sub-battery when needed, sustaining capacitor charging for timely defibrillation.

A medical device generates composite pacing pulses by selectively coupling portions of a capacitor array to an output signal line.

A wearable cardioverter defibrillator unit outputs voice prompts to guide patients in swapping rechargeable batteries.

An IoT module integrated into automated external defibrillators collects usage data and transmits location information to resolve limited tracking capabilities.

High pass filter isolates intrinsic cardiac nerve activity from heart electrical noise, enabling early arrhythmia prediction without stellate ganglia surgery.

Periodic self-tests and dynamic alert adjustments conserve battery power in automatic external defibrillators while maintaining reliable status visibility.

Implantable device discriminates hypervolemia and euvolemia using time-domain and frequency-domain signal analysis, preventing fluid overload complications.

Ultrashort pulse laser ablation forms planar connecting surfaces on the pin ends, preventing microcracks and uncontrolled solder flow during manufacturing.

A medical device control panel repositions to expose distinct user interfaces.

An implantable system uses optical triggers to synchronize therapy delivery between leadless devices.

An extra-cardiovascular ICD uses pericardial electrodes to deliver high-voltage pulses for tachyarrhythmia induction.

Segmenting defibrillation into multiple impedance-adaptive paths reduces excitable gaps and improves myocardial depolarization success.
