Configurable Wound Dressing Kit for Pressure Therapy Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Healthcare professionals need to maintain separate stocks of wound dressings for pressure gradient wound therapy and standard wound treatment, which is space-consuming and complex, and there is a lack of versatile dressings that can be used with or without pressure gradient therapy as needed.
Innovation Solution
A kit containing a piercing tool and optional components to convert a standard wound dressing into a pressure gradient-compatible configuration by creating an aperture in the covering layer, allowing it to be used with or without pressure gradient therapy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate stocks of dressings are maintained for pressure gradient therapy and standard treatment, then the reliability of having appropriate dressings for specific needs is improved, but the device complexity and space requirements increase
Solution Approach 1:
The wound dressing is designed with dual functionality: it can be used as a standard sealed dressing or converted to a pressure gradient therapy dressing by creating an aperture. The covering layer is made pierceable to allow conversion, enabling a single dressing type to serve both purposes and eliminating the need for separate stocking of different dressing types.
2Adaptability or versatility
If a piercing tool is used to create an aperture in the covering layer, then the adaptability of the dressing for pressure gradient therapy is improved, but the ease of operation decreases due to additional steps
Solution Approach 1:
The covering layer is pre-designed with specific properties (pierceable but sealed) to enable easy conversion. The piercing tool is provided as a simple, dedicated device that can create the aperture quickly. The dressing is packaged in a way that maintains sterility while allowing easy access to the piercing tool and instructions, reducing the operational burden on healthcare professionals.
3Adaptability or versatility
If the covering layer is made pierceable for conversion, then the versatility of the dressing is improved, but the risk of contamination increases
Solution Approach 1:
The aperture is created only when needed and only in a controlled manner using the provided piercing tool. The covering layer is designed to remain fully sealed during storage and initial application, maintaining sterility. The piercing action is intended to be performed quickly and cleanly, minimizing exposure time to potential contaminants.
Solution Approach 2:
The piercing tool serves as a sterile intermediary that creates the aperture in a controlled manner. It is provided in sterile packaging and designed to maintain sterility during the piercing process, acting as a barrier between the external environment and the wound dressing interior during the conversion process.

AI summary
Kit for use with A Selectively Configurable Wound Dressing A packaged kit of parts is provided for use with a selectively configurable wound dressing. The kit includes a piercing tool configured to pierce a covering layer of the wound dressing to produce an aperture therein and thereby configure the wound dressing for use in a pressure gradient wound therapy system. The kit may also include a) packaging indicating that the piercing tool is configured to pierce a covering layer of a wound dressing; (b) instructions instructing a user as to how to use the piecing tool; (c) one or more selectively configurable wound dressings; (d) a source of non-atmospheric pressure; (e) a port to connect the wound dressing to a source of non-atmospheric pressure; or (f) tubing for connection between a wound dressing and a source of non-atmospheric pressure. The kit is arranged within a sealed package.
