Solution Overview
Problem
Current endoluminal negative pressure therapy for gastrointestinal tract wounds faces challenges in simplifying handling, shortening procedure duration, and enhancing safety due to complex endoscopic component management and suboptimal sizing of absorbent bodies for precise wound site adaptation.
Innovation Solution
A medical kit comprising multiple absorbent bodies with varying diameters and lengths, each with a permanently attached suction hose, allowing for flexible selection and precise adaptation to wound sites through endoscopic measurement, along with a connector system for easy translocation and a grasping loop for precise placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-size absorbent body is used, then the device complexity is reduced, but the manufacturing precision and adaptability to different wound sites deteriorate
Solution Approach 1:
The kit divides the absorbent bodies into multiple size segments (different diameters and lengths) to match various wound cavity dimensions. This segmentation allows precise adaptation to different wound sites without requiring complex adjustable mechanisms, thus resolving the contradiction between device complexity and sizing precision.
Solution Approach 2:
The invention changes the dimensional parameters (diameter and length) of the absorbent bodies to create a range of sizes. This parameter variation enables selection of the optimal size for each specific wound site, improving manufacturing precision and adaptability while maintaining simple device design.
2Adaptability or versatility
If multiple absorbent bodies with varying sizes are provided, then the adaptability to different wound sites is improved, but the device complexity increases
Solution Approach 1:
The kit segments the absorbent bodies into standardized size categories, making it easy to select the appropriate size for different wound sites. This segmentation approach improves adaptability while keeping the device structure simple and manageable.
Solution Approach 2:
The kit provides a universal solution by including multiple absorbent bodies that can all be used with the same application system. Each absorbent body serves the same function but in different size requirements, enhancing versatility without increasing the complexity of the core device.
3Ease of manufacture
If the suction hose is not permanently attached, then the ease of manufacture is improved, but the reliability of the connection deteriorates
Solution Approach 1:
The suction hose is permanently merged with the absorbent body through adhesive bonding, creating a single integrated component. This merging ensures reliable connection during use while simplifying the manufacturing process by eliminating the need for separate attachment mechanisms.
4Measurement precision
If the endoscopic procedure requires complex component management, then the measurement precision can be improved, but the ease of operation deteriorates
Solution Approach 1:
The appropriate absorbent body size is determined through preliminary endoscopic measurement of the wound cavity before the procedure. This preliminary action allows selection of the correct size in advance, improving measurement precision while simplifying the actual operation by eliminating complex intra-procedural adjustments.
