Integrated Sterilizing Cabinet Cart for Floor-Loaded Steam Sterilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sterilization methods for surgical instruments and medical devices in floor loading sterilizers face challenges in ensuring uniform steam penetration and maintaining sterility during multiple cycles, requiring careful arrangement and repeated filter inspections.
Innovation Solution
An integrated wheeled case cart and sterilizing cabinet system that can withstand multiple sterilization cycles, allowing for easy loading and unloading without vertical translation, with a sterilizing cabinet positioned at a surgical field-compliant height and equipped with filters to ensure effective steam penetration and sterility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If items are loaded into a sterilizing cabinet for floor loading sterilization, then sterilization can be performed, but the cabinet must be vertically handled and repeatedly loaded/unloaded which increases complexity and potential contamination risk
Solution Approach 1:
The patent combines the sterilizing cabinet with the wheeled case cart into a single integrated unit. The sterilizing cabinet is mounted on the cart frame, and both are sterilized together as one assembly. This eliminates the need to separately handle and load/unload the cabinet, reducing procedural complexity and contamination risk while maintaining sterility throughout multiple cycles.
2Productivity
If the sterilizing cabinet is integrated with the wheeled case cart, then vertical handling is eliminated and efficiency improves, but the integrated unit must withstand multiple sterilization cycles which requires enhanced durability
Solution Approach 1:
The sterilizing cabinet is permanently mounted on the wheeled case cart frame, creating an integrated unit that is sterilized together. This eliminates repeated vertical handling and loading/unloading operations, improving efficiency. The entire assembly is designed to withstand multiple sterilization cycles, with the cart frame and cabinet constructed from materials suitable for repeated autoclaving.
3Reliability
If filters are placed over vents to maintain sterility, then contamination is prevented, but the filters must be removed and inspected after each cycle which increases time consumption
Solution Approach 1:
The integrated design allows the entire sterilizing cabinet assembly to be sterilized together with its contents. The system maintains sterility through the integrated sterilization process rather than relying on separate filter inspection and replacement procedures after each cycle, reducing time consumption while maintaining sterility assurance.
4Ease of operation
If the sterilizing cabinet is positioned at surgical field height, then accessibility is improved, but the cabinet requires precise height adjustment which increases device complexity
Solution Approach 1:
The wheeled case cart is designed with adjustable height features that allow the sterilizing cabinet to be positioned at the appropriate surgical field height. The adjustability is built into the cart structure, enabling easy height modification without requiring complex external adjustment mechanisms, thus improving accessibility while minimizing added complexity.
