Compliant Wound Irrigation Device With Selective Debridement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wound irrigation and debridement methods often lead to environmental contamination, require cumbersome setups, and limit visibility and access to the wound site, making them inefficient and potentially hazardous for both patients and medical personnel.
Innovation Solution
A device with a compliant region for fluid containment and a debridement region that can be selectively engaged to perform mechanical debridement, allowing for improved fluid management and reduced contamination, while maintaining contact with the wound bed to facilitate irrigation and debridement without direct hand contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wound irrigation and debridement methods are used, then the wound can be cleaned and debrided, but environmental contamination increases and occupational hazards arise
Solution Approach 1:
The patent employs a flexible containment device with a compliant region that forms a barrier between the wound site and the environment. This flexible shell contains irrigation fluid and captures debris, preventing environmental contamination while maintaining effective wound cleaning through controlled irrigation and mechanical debridement actions.
2Ease of operation
If direct hand contact with the wound bed is used for debridement, then mechanical debridement can be performed, but occupational hazards increase
Solution Approach 1:
The patent introduces a containment device with a debridement region as an intermediary between the operator's hand and the wound bed. This intermediary structure allows mechanical debridement to be performed through the device rather than direct hand contact, reducing occupational hazards while maintaining debridement effectiveness.
3Quantity of substance
If traditional irrigation setups are used, then wound irrigation can be performed, but fluid management becomes cumbersome and visibility is limited
Solution Approach 1:
The patent combines irrigation fluid delivery, containment, and debridement functions into a single integrated device. The containment device merges the irrigation system with the debridement tool, allowing fluid management to be performed through the same device that delivers irrigation and performs debridement, thereby simplifying overall fluid management and improving ease of operation.
4Ease of operation
If the debridement region is always in contact with the wound bed, then mechanical debridement is available, but the compliant region cannot maintain optimal contact
Solution Approach 1:
The patent designs the debridement region to be movable relative to the compliant region, allowing dynamic adjustment of contact. The debridement region can be selectively engaged with the wound bed while the compliant region maintains contact, enabling the device to adapt its configuration based on the specific procedural needs without compromising the reliability of contact engagement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device minimizes fluid and debris release into the environment, enhances visibility during procedures, reduces occupational hazards, and allows for efficient, one-handed operation, making wound irrigation and debridement more effective and safer.
Implementation Method 1
the compliant region is compressed along the longitudinal axis to define a second axial dimension less than the first axial dimension
Implementation Method 2
the compliant region is porous and defines a plurality of pores

AI summary
A device for wound irrigation and debridement includes a body extending along a longitudinal axis. The body comprises an interior region and an opening such that that the interior region and the first opening are configured to transfer an irrigation fluid. The body comprises a compliant region having a first stiffness and a debridement region having a different second stiffness. The compliant region defines a distal surface. In a first configuration, the compliant region defines a first axial dimension, the distal surface engages a target body region, and the debridement region is axially offset from the distal surface and disengaged from the target body region. In a second configuration, the compliant region is compressed to define a second axial dimension less than the first axial dimension, thereby engaging the debridement region with the target body region, and the distal surface engages the target body region.
