In-Vitro Diagnostic Calibration Management System
Solution Overview
Problem
In-vitro diagnostic systems face inefficiencies and increased costs due to the time-consuming and cumbersome process of managing calibration, particularly with varying reagent expiration dates and the need for frequent recalibrations, leading to delays and unnecessary calibrations.
Innovation Solution
A computer-implemented method for automatically managing calibration by determining lot calibration time periods, linking reagent containers to available calibrations, and triggering container-specific calibrations to optimize reagent use and minimize manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual calibration management is performed for each reagent container, then calibration accuracy is maintained, but user time and operational complexity increase significantly
Solution Approach 1:
The system automatically manages calibration assignments by monitoring reagent container usage, tracking lot calibration time periods, and autonomously assigning appropriate calibrations without requiring manual user intervention for each reagent container
Solution Approach 2:
The system continuously monitors reagent container status, calibration expiration dates, and usage patterns to dynamically determine when and which calibrations are needed, providing real-time feedback to optimize calibration scheduling
2Reliability
If frequent calibration procedures are performed to ensure system reliability, then measurement precision is maintained, but productivity and operational efficiency decrease
Solution Approach 1:
The system dynamically adjusts calibration scheduling based on actual reagent usage rates, container expiration dates, and lot calibration time periods, performing calibrations only when necessary rather than on fixed schedules
Solution Approach 2:
The system proactively identifies and assigns calibrations before they are needed by monitoring approaching expiration dates and lot calibration time periods, preventing delays while avoiding unnecessary calibration procedures
3Productivity
If lot calibration time periods are extended to reduce calibration frequency, then productivity improves, but calibration reliability may be compromised
Solution Approach 1:
The system changes the parameter of calibration time period duration based on specific lot characteristics, reagent stability data, and usage patterns, optimizing the balance between calibration frequency and reliability for each situation
4Loss of energy
If reagent containers are used closer to expiration to maximize utilization, then cost efficiency improves, but the risk of calibration expiration and operational delays increases
Solution Approach 1:
The system performs preliminary identification of calibrations that need to be performed before reagent expiration by monitoring expiration dates and lot calibration time periods, ensuring calibrations are completed in time while maximizing reagent utilization

AI summary
A computer-implemented method of automatically managing calibration of an in-vitro diagnostic system is provided comprising determining a lot calibration time period in which a lot calibration is applicable to reagent containers of the same lot, having a predefined time length starting from the time when the lot calibration becomes available, upon making a reagent container of the lot available to the system, determining whether a lot calibration that has not exceeded the lot calibration time period is available and linking the reagent container to the available lot calibration or most recent available lot calibration if more than one lot calibration is available, wherein if a new lot calibration for the same lot becomes available the method comprises replacing the existing link to the previous lot calibration with a link to the new lot calibration.
