Foldable Wrap Assemblies for Urinary Catheterization Kits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical device kits lack an organized and sterile system for placing, maintaining, and removing medical devices, often leading to complications and contamination during procedures.
Innovation Solution
The development of medical device kits featuring rollable or foldable wrap assemblies with sterilizable materials, ultrasonically welded pockets, and integrated instructions that maintain an aseptic field, allowing for a stepwise system for procedures like urinary catheterization, which includes essential components and facilitates aseptic handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional medical device kits are used without organized wrap assemblies, then the kits are simpler in structure, but the procedures lack sterile organization and increase contamination risk
Solution Approach 1:
The wrap assembly merges multiple separate kit components (sterile drape, instrument tray, surgical pack) into a single integrated unit. The wrap body contains pockets that hold instruments and accessories, while maintaining a sterile field, thus reducing the number of separate items while improving organization and sterility reliability.
Solution Approach 2:
The wrap assembly serves multiple functions simultaneously: it provides a sterile field, organizes instruments, contains accessories, and facilitates procedural steps. This multi-functionality reduces the need for separate specialized components, resolving the contradiction between simplicity and functional completeness.
2Productivity
If components are not arranged in predetermined order in pockets, then the wrap assembly is simpler to manufacture, but the procedure efficiency decreases
Solution Approach 1:
Components are pre-arranged in pockets in the predetermined order of use during manufacturing. This preliminary organization eliminates the need for real-time sorting and arranging during the procedure, significantly improving procedural efficiency while the arrangement process is integrated into standard manufacturing workflows.
3Reliability
If foldable edges are not included on the wrap body, then the wrap body is simpler in structure, but components may slip off and aseptic field is compromised
Solution Approach 1:
The wrap body includes folded edges that create segmented, reinforced boundaries. These edges are folded back to form protective flaps that prevent components from slipping off while maintaining the sterile field integrity. The segmentation adds minimal structural complexity while significantly improving reliability.
4Ease of manufacture
If trays are used to hold components, then components are easily accessible, but manufacturing costs and environmental impact increase
Solution Approach 1:
The invention extracts the component-holding function from separate trays and integrates it directly into the wrap assembly structure. The pockets are formed as integral parts of the wrap body, eliminating the need for separate tray components. This reduces manufacturing steps, material usage, and costs while maintaining component accessibility during procedures.
Applied Scientific Principles
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 kits provide a sterile and organized environment for medical procedures, reducing contamination risks and improving the efficiency of medical device placement, maintenance, and removal, while also reducing manufacturing costs and environmental impact by eliminating the need for trays.
Implementation Method 1
The pockets are formed by one or more pieces of wrap-body material welded to the wrap body by ultrasonic welds defining bottoms and sides of the pockets

AI summary
A wrap assembly for a urinary catheterization procedure includes a foldable wrap body, a first plurality of urinary catheterization components and a second plurality of urinary catheterization components. The foldable wrap body can be formed of a fabric and can include a first sterile component placement area and a second sterile component placement area positioned under the first sterile component placement area. The first plurality of urinary catheterization components can be placed onto the fabric of the first sterile component placement area in a first order of use for the urinary catheterization procedure. The second plurality of urinary catheterization components can be placed onto the fabric of the second sterile component placement area in a second order of use for the urinary catheterization procedure.
