Sterilization Wrap With Inner Strength Sheet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sterilization wraps for instrument trays and surgical supplies often tear or rip during storage and transportation due to the weight of the contents, necessitating repeated sterilization procedures and compromising sterility.
Innovation Solution
A sterilization wrap comprising a first sheet that allows sterilization gas penetration while preventing bacterial ingress, with a second sheet attached to provide additional strength, configured to prevent tearing and ripping, and optionally oriented at angles to enhance coverage and attachment through adhesives or fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single sterilization wrap sheet is used, then the wrapping process is simple and quick, but the wrap tears or rips under the weight of heavy instrument trays (25-30 pounds or more)
Solution Approach 1:
The patent applies composite materials by combining two different sheets: a sterilization wrap sheet (which allows sterilization gas penetration) and a strength sheet (which provides structural support and tear resistance). This composite structure resolves the contradiction by allowing each material to perform its specialized function - the sterilization wrap maintains sterility while the strength sheet prevents tearing under heavy loads.
Solution Approach 2:
The patent segments the protective packaging function into two distinct components: the sterilization wrap sheet that provides microbial barrier properties and the strength sheet that provides mechanical strength. This segmentation allows each component to be optimized for its specific purpose without compromise.
2Strength
If double wrapping with two sterilization sheets is performed, then tear resistance improves, but the sterilization gas penetration capability deteriorates due to excessive layering
Solution Approach 1:
Instead of using two sterilization wrap sheets that would both restrict gas penetration, the patent uses a composite of one sterilization wrap sheet and one strength sheet. The strength sheet provides the needed tear resistance without significantly impeding sterilization gas penetration, as it can be designed with appropriate porosity or material properties.
Solution Approach 2:
The patent applies local quality by giving different regions of the packaging different properties: the sterilization wrap sheet provides microbial barrier properties where needed, while the strength sheet provides mechanical support. This localized functional differentiation optimizes both sterility and strength without over-packaging.
3Area of stationary object
If the second sheet is positioned with perimeter extending beyond the first sheet, then coverage is maximized, but the risk of tearing at the edges increases
Solution Approach 1:
The patent employs asymmetric positioning where the strength sheet's perimeter is contained entirely within the sterilization wrap sheet's perimeter. This asymmetric arrangement ensures that the weaker sterilization wrap sheet extends beyond the stronger strength sheet, providing a protective border that prevents edge tearing while the strength sheet provides core structural support.

Function Achieved in This Case
The enhanced sterilization wrap provides improved durability and resistance to tearing, ensuring the sterility of contents from sterilization to use, reducing the need for repeated wrapping and sterilization processes.

Data Source
AI summary
A sterilization wrap is provided. The sterilization wrap includes a first sheet that is configured for providing a barrier to prevent at least some bacteria from passing therethrough while allowing sterilization gas to pass therethrough. A second sheet is attached to the first sheet. The second sheet is located on the first sheet so that a perimeter of the second sheet is contained entirely within a perimeter of the first sheet.
