Surgical Site Preparation Device with Sterile Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices do not address the specific protocol involving a non-sterile and sterile operator for preparing a skin site in the operating room, which requires separate cleaning and painting operations with varying materials and liquids, lacking a comprehensive solution for efficient and safe material provision.
Innovation Solution
A device comprising individual containers for debridement, preliminary painting, and final painting materials, where the final painting material is sealed and isolated in a sterile envelope, allowing a non-sterile worker to perform initial operations and a sterile worker to complete the final painting, with materials organized in a stackable assembly container for efficient use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If materials are placed in individual containers and organized in a stackable assembly container, then ease of operation and time efficiency are improved, but device complexity increases
Solution Approach 1:
The device divides surgical materials into separate individual containers (first container for cleaning materials, second container for first painting materials, third container for second painting materials). Each container is independently organized and can be stacked, allowing efficient access and reducing time to locate specific materials during the surgical procedure.
Solution Approach 2:
The individual containers are designed to be stacked within an assembly container, creating a nested structure where smaller containers are placed inside a larger organizing structure. This nesting approach consolidates multiple materials into a single portable unit while maintaining individual accessibility.
2Reliability
If the final painting material is sealed and isolated in a sterile envelope, then reliability and safety are improved, but device complexity increases
Solution Approach 1:
The third container holding the final painting materials is completely separated and sealed within the sterile envelope, isolated from the non-sterile cleaning and first painting materials. This extraction ensures that only sterile items are placed in the sterile barrier, maintaining strict sterility boundaries.
Solution Approach 2:
The sterile envelope acts as an intermediary barrier between the non-sterile environment and the final painting materials. This intermediate sterile barrier protects the critical painting materials from contamination while allowing controlled access during the surgical procedure.
3Ease of operation
If separate containers are used for cleaning and painting materials, then ease of operation is improved, but loss of time in assembly increases
Solution Approach 1:
All materials are pre-assembled into the stacked container configuration before the surgical procedure begins. The containers are pre-organized with cleaning materials in the first container, first painting materials in the second container, and final painting materials in the third container, eliminating the need for time-consuming assembly during the procedure.

AI summary
The device has individual containers (30, 40, 50) that contain initial and final treatment materials and cleaning materials (3 - 5), respectively, and are reunited in a sachet (1) in sterile conditions. The final treatment material container is sealed and isolated in an individual sealed casing such that preliminary site cleaning and treatment operations are performed by a non-sterile caregiver and a final site cleaning operation is performed by a sterile caregiver. The final treatment material (3) is constituted of a cup that receives a disinfectant product.
