Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current compression therapy systems for venous insufficiency are inadequate for patients with both venous insufficiency and arterial occlusive disease, as they lack comprehensive monitoring to ensure safe pressure application, potentially leading to hypoperfusion and tissue damage.
Innovation Solution
A system incorporating a compression means, a pressure sensor, and a pulse oximetric oxygen sensor that transmits data to a computer for real-time monitoring and alarm generation if pressure or oxygen saturation falls outside predetermined ranges, enabling simultaneous monitoring of pressure and oxygen saturation to ensure safe therapy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compression therapy is applied to patients with venous insufficiency and arterial occlusive disease, then venous hypertension is reduced and blood supply is improved, but hypoperfusion and tissue destruction may occur
Solution Approach 1:
The system continuously monitors oxygen saturation levels and pressure during compression therapy, providing real-time feedback to detect hypoperfusion conditions. When oxygen saturation falls below a predetermined threshold or pressure exceeds safe limits, the system generates alarm signals to alert medical personnel, enabling timely intervention to prevent tissue damage.
Solution Approach 2:
The system performs preliminary checks of pressure and oxygen saturation levels before and during compression therapy application. By establishing predetermined safe pressure ranges and oxygen saturation thresholds in advance, the system prevents dangerous conditions from developing, allowing safe compression therapy in patients with arterial occlusive disease who were previously considered high-risk.
2Measurement precision
If only pressure monitoring is used in compression therapy, then application pressure can be controlled, but comprehensive safety monitoring for patients with arterial occlusive disease is insufficient
Solution Approach 1:
The system combines pressure monitoring with pulse oximetric oxygen saturation monitoring in a single integrated compression therapy system. This merging of multiple monitoring functions provides comprehensive safety monitoring that detects both pressure-related issues and oxygenation problems, enabling reliable detection of hypoperfusion conditions that pressure monitoring alone cannot identify.
3Reliability
If compression therapy is avoided in patients with arterial occlusive disease due to safety concerns, then tissue damage is prevented, but venous insufficiency treatment is denied
Solution Approach 1:
By implementing continuous feedback monitoring of oxygen saturation and pressure with automated alarm systems, the system provides objective safety assurance that enables compression therapy to be safely applied to patients with arterial occlusive disease who were previously excluded from treatment, thus expanding adaptability to broader patient groups.
