Solution Overview

Problem

Current point-of-care blood analysis systems in prehospital settings lack accuracy and require manual interpretation and documentation by less trained personnel, leading to inefficiencies in medical decision-making and treatment delays for patients in emergency situations.

Innovation Solution

Integration of a portable point-of-care blood analyzer into a local area network for an emergency monitor-defibrillator system, allowing for communicative connection with other medical devices and remote data systems, enabling automated blood analysis and instant result transmission to hospitals, along with intelligent selection criteria for diagnostic testing based on clinical decision rules and patient demographics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If point-of-care blood analysis systems are used in prehospital settings, then the time to obtain blood analysis results is reduced, but the accuracy of the blood analysis decreases

Engineering Contradiction:

Improvetime to obtain blood analysis resultsVSAvoidaccuracy of blood analysis

Core Design Contradiction:

Loss of timeVSMeasurement precision

Solution Approach 1:

The patent combines multiple blood analysis functions into an integrated point-of-care system that can perform various types of blood tests (including contrast-induced nephropathy risk assessment) at the patient's side, merging the benefits of rapid POC testing with comprehensive diagnostic capabilities that maintain accuracy through integrated multi-analyte measurement

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system performs blood analysis before contrast imaging procedures in advance, allowing hospitals to prepare appropriately. The preliminary blood test results enable pre-procedure risk stratification and preventive measures to be implemented before the actual contrast imaging occurs

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If blood analysis is performed in a hospital laboratory, then the accuracy of blood analysis is maintained, but the time for medical decision-making is delayed

Engineering Contradiction:

Improveaccuracy of blood analysisVSAvoidtime for medical decision-making

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent extracts the blood analysis function from the central hospital laboratory setting and places it at the point of care in prehospital environments. This extraction allows blood testing to occur independently of hospital infrastructure, eliminating transport time and enabling immediate results while maintaining diagnostic quality through specialized POC instrumentation

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of operation

If prehospital providers manually interpret and document blood analysis results, then the process can be completed with less training, but the efficiency and speed of communication decrease

Engineering Contradiction:

Improveease of blood analysis interpretationVSAvoidefficiency of result communication

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The system enables self-service through automated features including electronic documentation that automatically records blood analysis results, clinical decision support that provides interpretation guidance, and electronic transmission that automatically sends results to receiving facilities, reducing manual burden while maintaining operational simplicity for providers

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements feedback mechanisms where blood analysis results are automatically transmitted to receiving facilities and integrated with patient electronic records, providing immediate feedback loops that enable continuous monitoring and rapid response to abnormal results without requiring manual follow-up

Inventive Principle:

Principle #23Feedback

4Reliability

If intelligent selection criteria are implemented for diagnostic testing, then the appropriateness of tests is improved, but the system complexity increases

Engineering Contradiction:

Improveappropriateness of diagnostic testingVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system implements universal clinical decision support rules that can be applied across multiple diagnostic scenarios and patient populations. The same intelligent selection criteria framework handles various blood test indications (including contrast-induced nephropathy risk assessment, acute kidney injury screening, and other emergency blood tests), providing reliable test selection without requiring separate complex systems for each indication

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A prehospital telemedicine system comprises a physiologic monitor; an electronic patient care reporting system (ePCR) system; and a point-of-care blood analyzer communicatively coupled to the physiologic monitor and the ePCR system. The point-of-care blood analyzer is configured to perform an analysis of a blood sample based on an indication of a need for a specific blood analysis provided by one of the physiologic monitor and the ePCR system, and to automatically transmit a result of the analysis to a remote data receiving system. The indication of a need for a specific blood analysis may be based upon any one of the following: vital signs data obtained for a patient by the physiologic monitor; and/or current documentation or past medical history captured on or available through the ePCR system.
