Tissue Matrix Mesh Packaging for Shape Retention and Aseptic Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging methods for acellular tissue matrix products result in surface or shape imperfections and do not facilitate aseptic transfer to sterile preparation areas, failing to meet surgeons' needs for uniform shape, thickness, and surface texture.
Innovation Solution
A packaging system comprising an inner mesh material and an outer barrier structure that retains the shape and surface cosmetics of the tissue matrix, using a mesh material to prevent air pockets and allow aseptic handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tissue is packaged in storage solutions inside a pouch, then the tissue is protected and stored, but surface or shape imperfections occur
Solution Approach 1:
The packaging system is divided into distinct functional layers: an inner mesh structure that contacts the tissue matrix, an outer barrier structure that provides protection, and a storage solution. This segmentation allows each layer to perform its specific function - the mesh structure prevents surface imperfections while the outer structure provides protection, resolving the contradiction between protection and surface quality.
Solution Approach 2:
The mesh structure serves as an intermediary between the tissue matrix and the storage solution. It allows the tissue to be protected from direct contact with the storage solution while preventing surface imperfections, acting as a mediator that maintains both protection and surface quality.
2Reliability
If current packaging methods are used, then tissue storage is effective, but aseptic transfer to sterile preparation area is not facilitated
Solution Approach 1:
The packaging is segmented into a removable inner structure containing the tissue matrix and a separate outer barrier structure. This allows the inner structure to be easily removed and transferred to sterile preparation areas while maintaining aseptic conditions, facilitating ease of operation without compromising storage effectiveness.
Solution Approach 2:
The packaging system is pre-assembled with the inner mesh structure, tissue matrix, and outer barrier structure in a controlled environment. This preliminary assembly ensures aseptic conditions are maintained throughout storage and transfer, eliminating the need for complex aseptic techniques during surgical procedures.
3Manufacturing precision
If mesh material is used to improve shape retention, then surface cosmetics are improved, but device complexity increases
Solution Approach 1:
The packaging is divided into distinct modular components - the inner mesh structure, outer barrier structure, and storage solution - that can be independently manufactured and assembled. This segmentation simplifies the overall device complexity by allowing each component to be optimized separately while maintaining the benefits of shape retention and surface cosmetics.
