Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating oxidative stress in patients are unreliable, complex, and time-consuming, particularly in critically ill or trauma patients, and there is a need for a simpler and faster method to determine overall oxidative status.
Innovation Solution
Measuring the oxidation-reduction potential (ORP) of body fluids or tissues using ORP electrodes, which provides an integrated measure of the balance between oxidants and reductants, aiding in diagnosis, evaluation, and monitoring of various conditions, including trauma, infections, myocardial infarction, and exercise performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple markers are measured to assess oxidative status, then measurement reliability improves, but measurement complexity and time consumption increase
Solution Approach 1:
The patent combines multiple oxidative stress markers into a single integrated ORP (oxidation-reduction potential) measurement. Instead of measuring separate markers like MDA, protein carbonyls, and antioxidant levels independently, the invention merges these assessments into one electrochemical measurement that reflects the overall oxidative status, thereby maintaining reliability while reducing complexity
Solution Approach 2:
The ORP measurement serves as a universal indicator for oxidative stress that can assess multiple aspects of oxidative status simultaneously. This single measurement functionally replaces multiple specialized assays, providing a multi-functional assessment tool that evaluates both pro-oxidant and antioxidant balance without requiring separate measurement systems
2Reliability
If multiple markers are measured to assess oxidative status, then measurement reliability improves, but time consumption increases
Solution Approach 1:
The patent merges multiple time-consuming oxidative stress assessments into a single rapid ORP measurement that can be performed in real-time or near-real-time, dramatically reducing the time required while maintaining comprehensive assessment of oxidative status
Solution Approach 2:
The invention replaces complex biochemical assay systems with an electrochemical measurement system. Instead of using time-intensive chemical reactions and spectrophotometric measurements for multiple markers, the patent uses an electrochemical sensor to directly measure ORP, substituting a fast electrical measurement for slow chemical analysis

AI summary
The present invention provides a method of determining the overall oxidative status of a body fluid or a tissue of a patient by measuring the oxidation-reduction potential (ORP) of the body fluid or tissue. The method has been found to be useful in the diagnosis, evaluation and monitoring of patients who have suffered a trauma (such as a head injury), patients suspected of being critically-ill or who are critically ill, patients who have an infection, and patients suspected of having a myocardial infarction (MI) or who have had an MI. The method has also been found useful in monitoring and evaluating exercise performance in patients. In addition, the method has been found useful in monitoring and evaluating stored blood products and patients who will receive such a product.
