Tissue Packaging Holder Channels for Orientation-Independent Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tissue storage techniques require specialized refrigeration or freezer equipment, limiting facility use and complicating transportation, and involve inconvenient pre-operative preparations, with known systems often needing a specific orientation to maintain fluid seals.
Innovation Solution
A packaging system comprising a holder and inner container with channels, an outer container, and a preservation solution, allowing room-temperature storage and facilitating easy handling and preservation of tissues in a fluid environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specialized refrigeration or freezer equipment is used to store tissue grafts, then tissue preservation is improved, but facility availability and transportation complexity worsen
Solution Approach 1:
The invention changes the storage temperature parameter from extreme cold (freezer temperatures) to refrigerated temperatures (2°C to 10°C), allowing tissue preservation without requiring specialized freezer equipment. The packaging system maintains this temperature range during storage and transportation, eliminating the need for complex cold chain logistics while preserving tissue viability.
Solution Approach 2:
The packaging system is divided into separate components: an outer container with insulation, an inner container holding the tissue, and a fluid reservoir. This segmentation allows the system to maintain refrigeration temperatures without requiring a single complex frozen unit, simplifying transportation and facility requirements while preserving tissue.
2Ease of manufacture
If dried tissue is used instead of wet-preserved tissue, then storage simplicity is improved, but pre-operative preparation time and inconvenience worsen
Solution Approach 1:
The tissue is pre-preserved in a fluid solution within the packaging system before use, maintaining its viability and readiness for implantation. This preliminary preservation action eliminates the need for time-consuming rehydration or preparation procedures that would be required if dried tissue were used, allowing surgeons to use the tissue immediately upon opening the package.
3Reliability
If traditional storage systems are used, then fluid seal maintenance is improved, but system orientation requirements worsen
Solution Approach 1:
The packaging system uses flexible membranes and seals that can adapt to different orientations and positions. The fluid reservoir and sealing mechanisms are designed to maintain the fluid seal regardless of how the container is positioned, eliminating orientation requirements while maintaining reliable fluid containment and tissue preservation.

AI summary
A packaging system includes a holder and an inner container. The holder includes a top portion and a bottom portion that cooperate to form a cavity configured to receive one or more medical products therein and to retain the one or more medical products therein. The inner container defines an interior region configured to receive the holder therein. The holder includes sidewalls that form the cavity, and the sidewalls include channels configured to fluidly connect the cavity to the interior region of the inner container.
