Disposable Consumable Memory Unit for Analyzer Reuse Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for effective monitoring and management of disposable consumables in medical diagnostic analyzers to ensure compliance with specifications and safety requirements, particularly for multi-use consumables that are reused across different analyzers.
Innovation Solution
A method involving the collection and storage of usage-relevant data in a memory unit attached to the consumable, allowing for evaluation and generation of control signals regarding the permissibility and type of further use, enabling reliable and safe reuse of disposable consumables across multiple analyzers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If disposable consumables are reused across multiple analyzers to reduce waste, then resource efficiency is improved, but the risk of misuse and contamination increases
Solution Approach 1:
The system implements feedback through usage data collection and evaluation. The memory unit stores usage information, which is read and evaluated by control devices to provide feedback on whether the consumable should be permitted for further use. This feedback mechanism ensures that reuse decisions are based on actual usage conditions, maintaining safety while enabling waste reduction.
Solution Approach 2:
The system performs preliminary actions by collecting and storing usage-relevant data before the consumable is reused. The usage data is evaluated in advance to determine permissibility of further use, and control signals are generated beforehand to prevent potential misuse. This preliminary verification ensures safety is maintained while allowing legitimate reuse.
2Reliability
If usage monitoring systems are implemented for disposable consumables, then reliability and safety are improved, but device complexity increases
Solution Approach 1:
The consumable itself provides self-service by containing an integrated memory unit that automatically stores usage-relevant data. This eliminates the need for external monitoring systems to track usage, as the consumable self-documented its usage conditions. The analyzer then simply reads this self-provided information, significantly reducing system complexity while maintaining reliable monitoring.
Solution Approach 2:
The memory unit serves multiple functions: it stores usage data, provides identification information, and enables traceability. This multi-functionality reduces the need for separate monitoring components, simplifying the overall system while achieving comprehensive consumable management and reliability improvement.

AI summary
A method for monitoring the use of a consumable in a disposable design in multiple analyzers is disclosed. The method provides a disposable consumable; uses the consumable as intended during operation of the first analyzer; and collects usage-relevant information for the consumable concerning the intended use of the consumable during operation of the first analyzer. Usage-relevant data derived from the usage-relevant information is stored in a memory unit assigned to the consumable. The consumable may be removed and again provided in the first or second analyzer. The first or second analyzer partially reads the usage-relevant data from the memory unit, evaluates the usage-relevant data, and derives control signals concerning the permissibility and/or type of a further intended use of the consumable during operation of the analyzer as a reaction to the evaluation of the read usage-relevant data.
