Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining the appropriate timing for surgical wound closure in traumatic injuries are subjective and lack objectivity, leading to variable outcomes and potential for unnecessary surgical interventions.
Innovation Solution
A computer-implemented method using a Bayesian Belief Network model that integrates wound effluent biomarker levels and clinical parameters to predict patient-specific wound healing outcomes and determine the optimal time for wound closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If subjective clinical assessment methods are used for wound closure determination, then the decision-making process is simple and quick, but the accuracy and reliability of wound healing prediction is poor
Solution Approach 1:
The patent replaces subjective clinical assessment (mechanical/physical evaluation) with an objective computational model based on Bayesian Belief Networks and proteomic biomarker analysis. This substitution transforms the assessment from human judgment to an automated, data-driven system that processes molecular data to predict wound healing outcomes with higher reliability.
Solution Approach 2:
The patent introduces wound effluent proteomic biomarkers as intermediaries between the wound state and clinical decision-making. These biomarkers serve as measurable indicators that mediate the relationship between wound conditions and healing predictions, providing objective data that bridges the gap between subjective assessment and reliable prediction.
2Measurement precision
If subjective clinical assessment is used, then the assessment process is fast and requires minimal resources, but intra-observer variability is high and measurement precision is low
Solution Approach 1:
The patent replaces time-consuming subjective clinical evaluation with rapid proteomic biomarker analysis combined with computational modeling. The Bayesian Belief Network model processes biomarker data quickly to provide precise wound status determination, reducing assessment time while improving measurement precision through objective molecular measurements.
Solution Approach 2:
The patent changes the measurement parameters from subjective clinical observations to objective proteomic biomarker concentrations. This parameter transformation enables precise, quantifiable measurement of wound healing status through molecular indicators, providing consistent and reproducible results that reduce intra-observer variability.
3Reliability
If aggressive surgical care with serial debridement is performed, then wound management is thorough, but the number of surgical interventions increases and patient morbidity risk increases
Solution Approach 1:
The patent implements a feedback mechanism where proteomic biomarker analysis continuously monitors wound healing status and provides predictive information about closure outcomes. This feedback loop enables clinicians to make informed decisions about the timing of wound closure, avoiding unnecessary serial debridement procedures and reducing surgical interventions while maintaining thorough wound management.
Solution Approach 2:
The patent performs preliminary assessment using proteomic biomarkers to predict wound healing outcomes before finalizing the surgical management plan. This preliminary action allows clinicians to determine the optimal timing for wound closure in advance, avoiding unnecessary surgical interventions and reducing patient morbidity risk while ensuring thorough wound management.
