Defibrillator Communications Module Power Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Defibrillators with communication capabilities face challenges in managing power usage effectively, risking depletion during data transfer, which is critical for maintaining functionality during cardiac incidents.
Innovation Solution
A communications module with a power supply system, power and data connectors, and a processor that controls power switching to enable data transfer between the defibrillator and the communications module without engaging the defibrillator's power supply, ensuring the defibrillator retains power for shock delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the defibrillator's power supply is engaged to transfer data between the defibrillator and external systems, then data communication functionality is enabled, but the defibrillator's power supply becomes depleted, reducing availability for shock delivery during cardiac incidents
Solution Approach 1:
The system segments the power supply function by introducing a separate power supply system in the communications module independent from the defibrillator's power supply. This allows data transfer operations to be powered separately, preventing depletion of the defibrillator's power supply while maintaining full data communication capability.
Solution Approach 2:
The communications module acts as an intermediary device with its own power supply system. It mediates between the defibrillator and external systems, enabling data transfer without requiring the defibrillator's power supply to be engaged, thus protecting the critical shock delivery function.
2Reliability
If the defibrillator performs self-tests and data transfers using its own power supply, then diagnostic and communication functions are maintained, but the power supply is depleted, compromising readiness for cardiac incidents
Solution Approach 1:
The power supply functions are segmented into two independent systems: the defibrillator's power supply for shock delivery and the communications module's power supply for diagnostic and communication operations. This segmentation allows both functions to operate simultaneously without competing for the same power resource, extending the effective duration of the defibrillator's power supply.
Solution Approach 2:
The system adds a new dimension of power independence by introducing a separate power supply system in the communications module. This dimensional change from a single shared power source to dual independent power sources resolves the conflict between maintaining diagnostic/communication functionality and preserving power supply duration for shock delivery.

AI summary
A communications module adapted for use with a defibrillator, comprising a power supply system configured to supply power to the communications module, a power connector adapted for connection to the defibrillator to provide power from the communications module to the defibrillator, a power switch connected between the power supply system and the power connector to transmit power from the power supply system to the power connector, a data connector adapted for connection to the defibrillator to transfer defibrillator data between the defibrillator and the communications module, and a processor configured to control the power switch to provide power from the communications module to the defibrillator to enable the transfer of the defibrillator data between the defibrillator and the communications module.
