Drug Injection Device Inactive-Time Control for Dosing Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical liquid infusion devices fail to accurately determine the exact amount of bolus injected when discarded due to abnormal reasons, leading to risks of over/under infusion.
Innovation Solution
A method and apparatus for determining an inactive time of a medical liquid dose calculator, which detects infusion errors and inactivates the calculator for a certain period when abnormal conditions occur, such as occlusion or communication errors, to prevent inaccurate dosing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the medical liquid infusion device is discarded due to abnormal reasons, then the device can be replaced or disposed of, but the exact amount of bolus injected cannot be determined
Solution Approach 1:
The system performs preliminary actions by automatically detecting infusion errors and calculating inactive times before the device is discarded. The controller monitors infusion status continuously and pre-determines the inactive time based on detected errors, ensuring that the bolus amount can be accurately determined even when the device is discarded due to abnormal reasons.
2Productivity
If the medical liquid dose calculator remains active after infusion error, then continuous dosing can be maintained, but over/under infusion risks increase
Solution Approach 1:
The system implements feedback mechanisms where the controller continuously monitors infusion status, detects errors, and adjusts the inactive time accordingly. This feedback loop ensures that the dose calculator is properly deactivated after infusion errors, preventing over/under infusion while maintaining continuous dosing capability through automated monitoring and adjustment.
3Productivity
If the inactive time is not determined, then the dosing calculation can continue without interruption, but inaccurate dosing may occur
Solution Approach 1:
The controller performs preliminary calculations to determine the inactive time based on detected infusion errors before the dosing calculation is affected. By pre-calculating the inactive time and using it to adjust the dosing calculation, the system maintains both continuity and accuracy of infused amount calculations even when infusion errors occur.
