Solution Overview

Problem

Current methods lack the ability to effectively screen newborn infants for the risk of developing necrotizing enterocolitis (NEC) early in their hospital stay, which is crucial for timely intervention and treatment.

Innovation Solution

Monitoring heart rate variability, specifically the high frequency component, to determine power levels that indicate an elevated risk for NEC, allowing for early identification and potential prophylactic treatment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional monitoring methods are used for newborn infants, then the current practice is simple and non-invasive, but the ability to early identify NEC risk is lost

Engineering Contradiction:

Improveearly identification accuracyVSAvoidmonitoring system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical/clinical monitoring methods with optical measurement technology. Specifically, it uses photoplethysmography (optical detection of blood volume changes) to measure heart rate variability, substituting the need for complex mechanical monitoring systems while achieving superior early identification accuracy for NEC risk.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces heart rate variability as an intermediary biomarker between the underlying NEC risk condition and observable clinical signs. By measuring HRV parameters (particularly high-frequency component power) as an intermediate indicator, the system enables early risk identification before manifest NEC symptoms occur, resolving the contradiction between early detection capability and monitoring complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If enhanced surveillance and intervention are implemented for high-risk infants, then treatment effectiveness improves, but the cost and resource consumption increase

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidresource consumption

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies preliminary action by identifying high-risk infants before NEC develops through early HRV measurement. By classifying infants as high-risk based on low high-frequency HRV power (below threshold values) during the first week of life, clinicians can implement targeted surveillance and preventive measures only for this subset, improving treatment effectiveness while avoiding unnecessary resource consumption for low-risk infants.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies local quality by transitioning from uniform monitoring of all infants to differentiated surveillance based on individual risk profiles. Infants are stratified into high-risk and low-risk groups based on their HRV characteristics, allowing intensive resource allocation only to those who need it most, thus optimizing the balance between treatment effectiveness and resource consumption.

Inventive Principle:

Principle #3Local quality
