Disposable Sensor Reuse Detection With Life Expectancy Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical disposable sensors face challenges in maintaining sterilization due to the potential reuse of disposable sensing components, which can lead to contamination and errors, as these components are designed for single use but may be reused intentionally or unintentionally.
Innovation Solution
A method and system that involve a controller component and a sensing component, where the controller reads device information, determines if the sensing component has been reused by checking a database, and if not reused, calculates the life expectancy of the sensing component using data analysis with a binning method, generating alerts for reuse and expiration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disposable sensing components are replaced after each single use to maintain sterilization, then sterilization standards are maintained, but device complexity and operational burden increase
Solution Approach 1:
The system implements automatic tracking and detection of sensing component usage status through database recording and controller verification. The controller automatically detects reuse attempts by checking device information against the database, providing real-time feedback and generating alerts without requiring manual tracking, thus maintaining sterilization standards while reducing operational burden
Solution Approach 2:
A database serves as an intermediary between the sensing components and the controller system. It stores device information and usage records, enabling automatic verification of component status without direct manual intervention, thereby maintaining sterilization compliance while simplifying operational procedures
2Ease of operation
If disposable sensing components are reused to reduce operational burden, then operational burden decreases, but sterilization standards are compromised and contamination risk increases
Solution Approach 1:
The system provides automatic feedback through reuse alerts when a sensing component is detected to have been previously used. The controller compares device information against the database and immediately generates alerts, preventing contaminated components from being used while allowing legitimate reuse of properly reprocessed components, thus reducing operational burden without compromising sterilization standards
Solution Approach 2:
The database acts as an intermediary verification layer that automatically checks component status before use. It stores and retrieves device information to determine reuse status, enabling the system to distinguish between appropriate reuse and improper reuse of contaminated components, thereby maintaining safety while facilitating operational efficiency
3Measurement precision
If device information is tracked and stored in a database to detect reuse, then reuse detection accuracy improves, but data management complexity increases
Solution Approach 1:
The sensing components themselves carry unique device information that automatically identifies them in the database system. The components essentially self-identify through their embedded information, eliminating the need for manual tracking and reducing data management complexity while maintaining high reuse detection accuracy through automatic controller verification
4Reliability
If life expectancy is determined through data collection and analysis, then component reliability assessment improves, but processing time and computational resources increase
Solution Approach 1:
The system collects and analyzes data from sensing components during their operational lifecycle to pre-determine life expectancy before failure occurs. By continuously monitoring usage patterns and environmental conditions, the system proactively assesses component health and predicts remaining lifespan, enabling timely replacement decisions without requiring extensive post-failure analysis or delaying critical assessments

AI summary
A method for detecting reuse of a sensing component by a controller component is provide. The method includes: reading device information of the sensing component; determining if the sensing component is reused based on the device information; in an instance in which the sensing component is reused, generating a reuse alert; and in an instance in which the sensing component is not reused, determining a life expectancy of the sensing component.
