Tray Belts for Sterilization Wrap Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sterilization wraps for surgical instruments often tear or rip during and after sterilization processes due to tray degradation and external abrasion, leading to contamination and the need for re-wrapping and re-sterilization, with existing solutions like corner protectors and double wrapping being either ineffective or costly.
Innovation Solution
The use of tray belts made from flexible and durable materials, such as heavy-duty cloth or nonwoven fibers, which can be secured to the tray and/or outside the sterilization pack using hook-and-loop fasteners or adhesives, to prevent abrasion and puncture damage on both inner and outer surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If corner protectors are used to prevent inner surface tears, then protection against tray-induced damage is improved, but protection against outer surface rips is not achieved
Solution Approach 1:
The protective system is divided into two distinct components: corner protectors for the tray and an outer protective layer for the wrap. This segmentation allows each component to specialize in protecting against specific types of damage, with the outer protective layer specifically addressing outer surface rips that corner protectors cannot prevent.
Solution Approach 2:
The corner protectors are nested within the sterilization wrap, which itself is nested within an outer protective layer. This nested structure allows multiple protective functions to be combined in a compact arrangement, where the outer protective layer provides additional protection without interfering with the function of the corner protectors.
2Reliability
If double wrapping is used to reinforce the sterilization pack, then protection against tears and rips is improved, but labor intensity and cost increase
Solution Approach 1:
An outer protective layer acts as an intermediary between the sterilization wrap and external environmental factors such as abrasion, sharp objects, and moisture. This intermediary layer provides enhanced protection without requiring the complexity of double wrapping, as it specifically targets external damage sources while allowing the inner sterilization wrap to maintain its primary function.
3Productivity
If sterilization packs are heavily loaded for efficiency, then productivity is improved, but susceptibility to outer surface rips during relocation increases
Solution Approach 1:
The outer protective layer is applied beforehand to the sterilization wrap before the pack is loaded and relocated. This pre-applied protective layer acts as a cushion against external forces such as abrasion and impact that occur during relocation of heavily loaded packs, preventing rips and tears that would otherwise occur under the stress of moving heavy loads.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tray belts effectively prevent tears and rips on both the inner and outer surfaces of sterilization wraps, reducing contamination risks and the need for re-wrapping, while being cost-effective and easy to apply.
Implementation Method 1
secured to the tray and/or outside the sterilization pack using hook-and-loop fasteners
Implementation Method 2
adhesives, to prevent abrasion and puncture damage on both inner and outer surfaces

AI summary
The present invention is directed at methods of preventing damages of a sterilization wrap for surgical instruments by utilizing tray belts. The tray belts are composed of an elongate member of substantially same width and a fastening means for connecting the two ends of the member. The methods comprise the steps of placing surgical instruments inside a sterilization tray, securely the tray belts around the tray, and wrapping a sterile wrap around the tray to form a sterilization pack. The methods may further comprise securing additional tray belts around the sterilization pack.
