NFC Tissue Interface for Precise Abdominal Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current negative-pressure therapy systems lack efficient methods for precise placement and data collection at tissue interfaces, particularly in complex anatomical areas like the abdominal cavity.
Innovation Solution
The use of near field communication (NFC) technology integrated into a tissue interface system, which includes a first and second contact layer, a spacer layer, and a plurality of NFC location tags. These location tags are positioned between the contact layers and can collect treatment data, such as pressure, temperature, and fluid presence, within the abdominal cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If NFC location tags are integrated into the tissue interface, then placement precision and data collection capability are improved, but device complexity increases
Solution Approach 1:
The tissue interface is divided into multiple functional layers: a first contact layer with first perforations for negative pressure application, a second contact layer with second perforations for fluid collection, and a spacer layer with appendages for structural support. NFC location tags are integrated into specific layers to provide placement precision without compromising the overall structural integrity or negative pressure therapy function.
Solution Approach 2:
The tissue interface serves multiple functions simultaneously: it applies negative pressure to promote tissue growth, collects treatment data through integrated NFC location tags, and provides structural support through the spacer layer with appendages. This multi-functionality allows a single device to address both therapeutic and monitoring requirements without requiring separate systems.
2Loss of information
If multiple NFC location tags are positioned within the abdominal cavity, then data collection capability is improved, but the risk of misplaced tags increases
Solution Approach 1:
The tissue interface is pre-configured with NFC location tags at predetermined positions during manufacturing. The spacer layer with its appendages provides a pre-formed structural framework that guides the placement of location tags to specific zones within the abdominal cavity, ensuring consistent and reliable positioning without requiring manual adjustment during surgery.
Solution Approach 2:
The NFC location tags communicate with an external identifier tool to provide feedback on the actual position of each tag relative to the intended location. This feedback mechanism allows for verification and adjustment of tag placement to ensure accurate data collection from the correct treatment areas within the abdominal cavity.
3Area of stationary object
If the spacer layer includes multiple appendages radiating from a central portion, then coverage of treatment zones is improved, but manufacturing complexity increases
Solution Approach 1:
The spacer layer is segmented into multiple appendages radiating from a central portion, with each appendage extending to a specific treatment zone. This segmentation allows the single spacer layer to cover a large area while maintaining a relatively simple manufacturing process, as each appendage can be formed as part of an integrated structure rather than assembled from separate components.
