Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for diagnosing limb ischemia are costly, invasive, and often unnecessary, as they do not differentiate between ischemia and compartment syndrome, leading to potential complications and unnecessary procedures.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If distal perfusion catheters are preemptively introduced when limb ischemia is suspected, then the risk of acute compartment syndrome is mitigated, but the procedure becomes costly, invasive, and often unnecessary
Solution Approach 1:
The patent implements preliminary detection of limb ischemia using temperature sensors before committing to invasive distal perfusion catheter procedures. By detecting temperature changes that indicate ischemia early, the system enables timely intervention only when necessary, avoiding unnecessary invasive procedures while still mitigating the risk of acute compartment syndrome through early warning capability
Solution Approach 2:
The patent replaces the mechanical/invasive approach of preemptive distal perfusion catheter insertion with a non-invasive temperature-based detection system. The temperature sensor monitors intramuscular temperature changes that indicate ischemia, substituting the need for invasive mechanical intervention with a diagnostic thermal measurement system
2Productivity
If current diagnostic methods are used for limb ischemia, then procedures can be performed, but they do not differentiate between ischemia and compartment syndrome, leading to potential complications and unnecessary procedures
Solution Approach 1:
The patent applies local quality measurement by using temperature sensors placed specifically in the affected muscle compartment to detect localized temperature changes. This localized thermal measurement provides precise information about the specific compartment's status, enabling differentiation between ischemia (temperature decrease) and compartment syndrome (temperature increase from inflammation and pressure), thereby improving diagnostic precision
