Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clinicians face difficulties in locating and correcting fluid leaks at the drape in reduced pressure delivery systems, which impede the effectiveness of wound healing treatments by reducing the system's performance and treatment potential.
Innovation Solution
A system and method that includes a fluid leak detection mechanism using sensors and a graphical user interface with audible feedback to help clinicians locate and correct fluid leaks at the drape, utilizing a processing unit to generate alarms and adjust audible sounds to guide the clinician in sealing the leak.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a drape is used to seal the tissue site in a reduced pressure delivery system, then the reduced pressure can be maintained for effective wound healing, but fluid leaks at the drape become difficult to locate and correct
Solution Approach 1:
The system employs visual indicators that change color or provide visual feedback to indicate the location of fluid leaks at the drape. This allows clinicians to easily identify leak positions without complex detection equipment, resolving the contradiction between maintaining seal integrity and enabling easy leak detection.
Solution Approach 2:
The system provides real-time feedback to clinicians regarding fluid leak detection and location. By implementing a feedback mechanism that communicates leak status and position, the system maintains reliable sealing while enabling easy detection and correction of leaks.
2Device complexity
If clinicians manually inspect the drape for fluid leaks, then the system remains simple in structure, but the treatment time is increased and treatment potential is not fully realized
Solution Approach 1:
The system performs self-diagnosis by automatically detecting and indicating fluid leak locations through visual indicators. This eliminates the need for complex manual inspection procedures while minimizing treatment time loss, resolving the contradiction between system simplicity and treatment efficiency.
Solution Approach 2:
The system proactively detects and indicates fluid leaks before they significantly impact treatment effectiveness. By providing advance warning and location information through simple visual indicators, the system prevents time loss without requiring complex detection infrastructure.
3Device complexity
If fluid leaks are not promptly detected and corrected, then the system structure remains unchanged, but the reduced pressure application becomes inconsistent and tissue growth is compromised
Solution Approach 1:
Visual indicators provide immediate feedback on seal integrity and fluid leak status, enabling clinicians to maintain consistent reduced pressure application. This simple indication method ensures pressure consistency without adding complex detection mechanisms.
Solution Approach 2:
The feedback mechanism provides real-time information about seal integrity, allowing clinicians to promptly correct fluid leaks and maintain consistent reduced pressure. This ensures treatment effectiveness while keeping the detection mechanism simple.

AI summary
A system and method for performing tissue therapy may include applying a reduced pressure to a tissue site of a patient. A fluid parameter associated with applying a reduced pressure to the tissue site may be sensed. An audible fluid leak location sound may be generated in response to sensing the fluid parameter. The audible fluid leak location sound maybe altered in response to sensing that the fluid parameter changes. By altering the audible fluid leak location sound in response to sensing a change of the fluid parameter, a clinician may detect location of a fluid leak at the drape by applying force to the drape. The force applied to the drape may be a clinician pressing a finger onto an edge of the drape.
