Defibrillator Event Data Access Through Key-Based Server Mediation

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing defibrillators, particularly public access AEDs, often fail to transfer critical event data to healthcare professionals, leading to inadequate patient care due to data not being downloaded or promptly provided, especially when patients regain consciousness before professional responders arrive.

Innovation Solution

Systems and methods that enable medical professionals to access event data from defibrillators by using keys associated with patient cases, transmitted via NFC, RFID, QR codes, or temporary tattoos, ensuring data is stored and retrieved from a server for subsequent care.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If defibrillators store event data locally without automatic transmission, then data security and patient privacy are maintained, but healthcare professionals cannot access critical treatment information when needed

Engineering Contradiction:

Improveevent data accessibilityVSAvoiddata transmission system

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent introduces a server as an intermediary between the defibrillator and healthcare professionals. The defibrillator transmits event data to the server, which then provides authorized access to healthcare providers through computing devices. This mediator approach enables data accessibility without requiring direct complex connections between all devices.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system segments the data access architecture into distinct components: the defibrillator that collects data, a server that stores and manages data, and computing devices that provide access to healthcare professionals. This segmentation allows each component to perform its function independently while maintaining overall system simplicity.

Inventive Principle:

Principle #1Segmentation

2Loss of information

If defibrillators automatically transmit all event data to healthcare providers, then complete information is available for patient care, but data privacy and security control are compromised

Engineering Contradiction:

Improveevent data completenessVSAvoiddata privacy risk

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The server implements a feedback-controlled data transmission system that provides event data to healthcare professionals based on their authorization status and specific care needs. The system responds to access requests by verifying credentials and selectively releasing appropriate data portions, ensuring both completeness for authorized users and privacy protection.

Inventive Principle:

Principle #23Feedback

3Loss of time

If defibrillators require manual data downloading, then device simplicity is maintained, but time is lost in transferring critical information to healthcare professionals

Engineering Contradiction:

Improvedata transfer timeVSAvoidautomatic transmission system

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The defibrillator automatically transmits event data to the server as a preliminary action immediately after treatment, without waiting for manual intervention. This advance transmission ensures data is already available in the system when healthcare professionals need it, eliminating delays while the automated process manages the complexity.

Inventive Principle:

Principle #10Preliminary action

4Reliability

If defibrillators use complex authentication systems for data access, then data security is improved, but ease of operation for healthcare professionals deteriorates

Engineering Contradiction:

Improvedata access securityVSAvoiddata retrieval process

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The server automatically verifies healthcare professional credentials and provides data access without requiring complex manual authentication procedures. The system performs self-service security checks by comparing provided identifiers against stored credentials, maintaining high security while keeping the user interface simple and easy to operate.

Inventive Principle:

Principle #25Self-service

AI summary

An example method is performed by a defibrillator and includes obtaining event data regarding treatment provided to a patient. The method also includes obtaining a key that facilitates validating a request from a computing device to access the event data, associating the key with the event data, and transmitting the key and the event data to a server. Another example method is performed by a mobile device and includes obtaining an encoded version of an identifier of a medical device that is provided on the medical device. The medical device is configured to obtain event data regarding treatment provided to a patient. The method also includes obtaining a selection of a recipient for the event data, and causing a summary of the event data to be transmitted to the recipient.
