Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical waste collection systems face challenges in accommodating suction limit settings, particularly in procedures requiring lower vacuum levels, such as pediatric surgeries, and lack intuitive user interfaces for seamless operation and safety.
Innovation Solution
The system introduces a method for receiving user inputs to set and lock suction limits, preventing excessive vacuum levels and offering adjustable suction limits, along with an intuitive user interface that displays prompts for deactivating suction limit locks and intermittent suction modes, ensuring safe and controlled vacuum operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a cover is employed to shield the waste canisters from view, then privacy and hygiene are improved, but it becomes difficult to accommodate the cover with other components of the waste collection system in the housing
Solution Approach 1:
The cover assembly is nested within the housing structure, with the cover selectively movable between occluding and non-occluding positions. The housing is configured to receive and guide the cover's movement, allowing the cover to be integrated without adding external complexity. This nesting approach allows the cover to be accommodated within the existing housing footprint while still providing privacy and hygiene benefits.
2Productivity
If the vacuum source operates at a high suction level, then waste collection efficiency is improved, but it may be undesirable for certain procedures such as pediatric procedures
Solution Approach 1:
The system provides dynamic control of vacuum levels through the user interface, allowing the suction level to be adjusted based on the specific procedure requirements. The vacuum source can operate at high suction levels for efficient waste collection during general procedures, while allowing reduction to lower levels for sensitive procedures such as pediatric surgeries. This dynamic adjustability resolves the contradiction between collection efficiency and patient comfort.
3Reliability
If the user interface provides extensive controls for suction limit settings and locks, then safety and control are improved, but the interface complexity increases
Solution Approach 1:
The user interface employs self-explanatory controls and visual feedback mechanisms that guide users through suction limit settings and locking functions. The interface automatically provides relevant information and status indicators, reducing the cognitive load on users. Common functions are accessible through intuitive controls, while advanced safety features remain available but do not clutter the primary interface. This self-service approach maintains safety and control while minimizing perceived interface complexity.

AI summary
Methods for operating a medical waste collection system. The medical waste collection system includes a waste canister, a vacuum source, a user interface, and a controller. The controller operates the vacuum source so that an actual vacuum level does not exceed a suction limit set by the user through the user interface. A suction limit lock may be activated to permit the user to adjust the suction limit up to the suction limit lock and to prevent the user from adjusting the suction limit above the suction limit lock. If the user provides an input that indicates an attempt to adjust the suction limit above a selected vacuum level associated with the suction limit lock, then the user interface may display a prompt with an option to disable the suction limit lock.
