Fat-Loaded Skin Graft Applicator for Portable Wound Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to provide a rugged, low-weight, portable, modular, and sustainable wound treatment that effectively stabilizes and protects wounds, particularly in field conditions, while ensuring timely healing and minimizing infection risk.
Innovation Solution
The system includes an applicator configured to apply a fat material to a skin graft material, comprising a syringe, plunger, roller, screw, container, a preparation chamber, a loading chamber, an extrusion press, a vacuum source, a mesh screen, an input channel, an output channel, a blade, a frame, a retaining element, and a handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biological skin substitutes are used to provide a more intact extracellular matrix structure, then wound healing quality is improved, but device complexity and processing requirements increase
Solution Approach 1:
The biological skin substitute is segmented into a modular application system consisting of separate components (skin substitute material, fat material, applicator device) that can be prepared and stored independently, then assembled at the point of use. This reduces the complexity of preparing intact biological tissue while maintaining healing quality.
Solution Approach 2:
The skin substitute material and fat material are prepared in advance and stored in a stable state, with all necessary processing completed before application. This preliminary preparation simplifies the actual wound treatment process while ensuring high-quality biological materials are used.
2Reliability
If a comprehensive wound treatment system is developed to stabilize and protect wounds, then wound protection is improved, but device complexity increases
Solution Approach 1:
The applicator device is designed as a multi-functional tool that can apply both the skin substitute material and the fat material, and can also provide mechanical compression and securement. This universal device reduces the number of separate components needed while maintaining comprehensive wound protection capabilities.
Solution Approach 2:
Multiple wound treatment functions (application of skin substitute, application of fat material, compression, and securement) are merged into a single integrated applicator device. This combination simplifies the overall system structure while providing comprehensive wound protection.
3Ease of operation
If a portable wound treatment system is created for field use, then ease of transport is improved, but manufacturing complexity increases
Solution Approach 1:
The wound treatment system is divided into separate, independently manufacturable components (skin substitute material, fat material, applicator device) that can be produced through different manufacturing processes and then assembled. This segmentation enables specialized manufacturing for each component while maintaining overall portability.
Solution Approach 2:
The system incorporates disposable components that can be pre-packaged and sterilized, reducing the need for complex sterilization and assembly procedures in the field. These disposable elements simplify manufacturing while ensuring portability and reliability.
