Double Sequential Defibrillation Synchronization via Intermediary Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The administration of double sequential defibrillation (DSD) therapies is often haphazard and poorly timed due to human limitations in temporal perception and motor control, affecting the efficacy and safety of the treatment for cardiac arrest patients.
Innovation Solution
The development of systems and methods that provide a controlled, adjustable, and repeatable means for delivering multiple defibrillation shocks concurrently, using multiple defibrillators connected via a coordinated control system to ensure precise timing and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual coordination of multiple defibrillators is used, then operational simplicity is maintained, but timing precision and treatment efficacy deteriorate
Solution Approach 1:
A synchronization system acts as an intermediary between multiple defibrillators, receiving trigger signals from one defibrillator and coordinating the discharge timing of another. This mediator ensures precise timing synchronization without requiring complex direct integration between all device components, thus improving timing precision while managing system complexity.
2Reliability
If synchronized defibrillation is implemented, then treatment efficacy is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary synchronization setup and trigger signal configuration before actual defibrillation delivery. By pre-coordinating the timing parameters and establishing synchronization protocols in advance, the system ensures reliable treatment efficacy during the critical moment of shock delivery without requiring complex real-time coordination during the procedure itself.
3Productivity
If rapid shock delivery is achieved, then treatment speed is improved, but timing control precision deteriorates
Solution Approach 1:
The system replaces manual mechanical coordination with electronic signal-based synchronization. Trigger signals and coordination commands are transmitted electronically between defibrillators, enabling both rapid response times and precise timing control. This substitution of electronic control for manual coordination allows simultaneous achievement of fast treatment delivery and accurate timing synchronization.

AI summary
A defibrillation device for administering an electrotherapy, such as a dual-sequential defibrillation (DSD) electrotherapy. The defibrillation device can include a defibrillation therapy module, a physiological parameter module and a control module. The defibrillation therapy module can output one or more energies and the physiological parameter module can receive one or more physiological parameters, including electrocardiogram (ECG) data. The control module can analyze the physiological parameters to determine an indication for the administration of an electrotherapy and can determine a DSD electrotherapy. The DSD electrotherapy can be based at least in part on the physiological parameters, the indication for the administration of an electrotherapy or a review of the ECG data.
