Endoscope Storage Cart With Timed Locking and Status Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscopes require frequent reprocessing due to the inability of Automated Endoscope Reprocessors to completely dry internal channels, leading to rapid microbial growth, and existing storage solutions lack effective time tracking and security features, increasing operational costs and reducing availability.
Innovation Solution
A cart system with integrated timers, sensors, and locking mechanisms that track the storage time of endoscopes, provide visual indicators, and ensure secure storage by authorized users, preventing contaminated endoscopes from being used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual monitoring is used for endoscope storage time, then the storage system is simple, but the tracking precision and reliability are insufficient
Solution Approach 1:
The patent replaces manual mechanical monitoring with electronic timer devices and control systems that automatically track storage time. The timer device records when the endoscope is placed in storage and calculates elapsed time, providing precise digital measurement instead of manual tracking.
Solution Approach 2:
The storage cart system performs self-monitoring through integrated timers and sensors that automatically detect when endoscopes are placed or removed, eliminating the need for manual intervention. The system self-updates timing information and automatically indicates when reprocessing is needed.
2Reliability
If no locking mechanism is provided, then the storage cart is easy to operate, but the security and reliability are compromised
Solution Approach 1:
The locking mechanism is controlled by feedback from the timer device. When the stored time exceeds the safe usage period, the system automatically engages the lock to prevent removal of the endoscope, ensuring that contaminated endoscopes cannot be used. The lock responds to timing information to maintain safety.
Solution Approach 2:
The control system acts as an intermediary between the timer and locking mechanism. It processes timing data and determines when the lock should engage or disengage, providing a safety buffer that prevents direct manual access to potentially contaminated endoscopes.
3Loss of information
If visual indicators are added to show time status, then the information visibility is improved, but the device complexity increases
Solution Approach 1:
The patent uses color-coded visual indicators (such as lights or display elements) that change color or illuminate to indicate different time status states. For example, green may indicate the endoscope is safe for use, while red indicates it requires reprocessing, providing immediate visual information about the endoscope status.
4Productivity
If automated timing and locking systems are implemented, then the productivity and availability are improved, but the manufacturing complexity increases
Solution Approach 1:
The storage cart is designed as a multi-functional integrated system that combines storage, timing, monitoring, and locking functions in a single unit. The control system serves multiple purposes: it tracks time, controls the lock, provides visual indicators, and manages overall system operation, reducing the need for separate components.
