Handheld AED with Remote Control and Image Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Automated External Defibrillators (AEDs) are not designed for personal use, lack portability, and do not include communication systems for user safety, leading to delayed defibrillation and reduced survival rates from Sudden Cardiac Arrests caused by Ventricular Fibrillation or Ventricular Tachycardia.
Innovation Solution
A mobile, hand-held device integrating an AED into a smartphone or PDA, with a remote control for safe operation, GPS for location tracking, and communication with EMS, providing visual and audio guidance, and monitoring of rescue attempts to ensure proper electrode placement and timely defibrillation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If AED is integrated into handheld device for personal use, then portability and accessibility are improved, but device complexity increases
Solution Approach 1:
The patent combines AED functionality with a smartphone or PDA by integrating the defibrillator control unit, electrode pad connectors, and emergency communication capabilities into a single handheld device. This merging allows the device to serve both as a communication tool and a life-saving defibrillator, improving portability while managing complexity through functional integration
Solution Approach 2:
The handheld device performs multiple functions: it serves as a smartphone/PDA for daily use, an AED controller for cardiac emergencies, and an emergency communication device with GPS location tracking. This multi-functionality justifies the increased complexity by providing comprehensive emergency response capabilities in a single portable unit
2Object-affected harmful factors
If remote control is added for operator safety, then safety is improved, but device complexity increases
Solution Approach 1:
The patent introduces a remote control unit that acts as an intermediary between the user and the defibrillator control unit. This remote control allows the user to initiate defibrillation from a safe distance, preventing direct contact with the electrical discharge while still enabling device operation. The remote control communicates wirelessly or via wired connection with the main unit, providing safety without requiring complex physical isolation systems
3Reliability
If communication system is integrated for EMS contact, then reliability of rescue is improved, but device complexity increases
Solution Approach 1:
The patent merges emergency communication capabilities (GPS location tracking, cellular phone functions, text messaging) directly into the handheld device structure. This integration ensures that rescue coordination can be initiated automatically or manually without requiring separate communication equipment, improving reliability by ensuring communication functionality is always available when the device is present
Solution Approach 2:
The device pre-stores emergency contact information and can automatically transmit location data and emergency alerts to EMS services upon detecting a cardiac event or upon user activation. This preliminary preparation of communication channels ensures that help can be summoned immediately without delay for manual setup, enhancing rescue reliability
