External Defibrillator With Sealed Paddles and Automatic Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated external defibrillators (AEDs) are bulky, cumbersome, and have limited portability, which delays defibrillation in emergency situations, and they often require users to navigate to a device, wasting precious time that can lead to reduced survival rates for cardiac arrest victims.
Innovation Solution
A compact, portable defibrillator design featuring sealed paddles with a frangible seal that automatically charges upon opening, integrated electrical systems, and conductive protrusions to reduce skin resistance, along with a connecting structure for instructional guidance, allowing for immediate use and reduced complexity in operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a conventional AED with base unit and cables is used, then defibrillation can be delivered, but the device is bulky and has limited portability
Solution Approach 1:
The defibrillator is divided into two separate paddles that can be held one in each hand, eliminating the need for a bulky base unit and cables. Each paddle contains integrated electrodes and conductive gel, allowing the device to be compact and portable while maintaining defibrillation capability.
Solution Approach 2:
The electrodes and conductive gel are integrated directly into the paddle structure itself, merging previously separate components (electrodes, gel, housing) into a unified compact paddle design that improves portability without sacrificing functionality.
2Loss of time
If a conventional AED requires navigation to the device, then the device is readily available, but precious time is wasted
Solution Approach 1:
The paddles are pre-assembled with electrodes and conductive gel already in place within a protective housing. The frangible seal is pre-positioned to break upon separation of the paddles, automatically initiating the defibrillation sequence without requiring users to navigate through menus or perform setup steps.
Solution Approach 2:
The frangible seal automatically breaks when the paddles are separated, triggering the defibrillation sequence without user intervention. The device performs self-initialization actions (breaking the seal, starting the sequence) that eliminate time-wasting manual operations.
3Volume of moving object
If paddles are sealed together in a protective housing, then the device is compact and portable, but the housing adds structural complexity
Solution Approach 1:
A frangible seal made of breakable material (such as frangible tape or a weak bond layer) is used to seal the paddles together. This thin, simple sealing mechanism provides protection and compactness without adding complex structural elements, and it automatically breaks when force is applied to separate the paddles.

AI summary
A variety of arrangements and methods relating to a defibrillator and a multiphasic pulse generator are described. In one aspect of the invention, a defibrillator includes two paddles that each include a defibrillator electrode covered in a protective housing. The two paddles are sealed together using a releasable seal to form a paddle module such that the housings of the paddles form the exterior of the paddle module. The multi-phasioc pulse generator includes a first subsystem, a second subsystem, and a switching component is electrically coupled with the paddles. The first subsystem and the second subsystem are arranged to generate a first phase of a pulse and a second phase of the pulse, the first phase of the pulse having a positive phase or a negative phase, and the second phase of the pulse having a phase in opposite polarity to the first phase of the pulse. The switching component switches between the first subsystem and the second subsystem to generate a therapeutic pulse having at least a positive phase and a negative phase.
