Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current contrast medium injection management systems lack accuracy in tracking and managing the injection amount, potentially leading to excessive use and interruptions in medical imaging procedures.
Innovation Solution
A contrast medium injection management apparatus that includes a measuring unit to track the injection amount, a cumulative injection amount calculator, and a display unit that alerts operators when the cumulative injection approaches or exceeds a predetermined ratio or amount, allowing for real-time adjustments to ensure safe and efficient use of contrast medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If contrast medium injection amount is estimated from bottle content and automatic injector data, then management process is simple, but management accuracy is insufficient
Solution Approach 1:
The management apparatus is integrated within the radiodiagnostic system, with the injection amount management function nested within the existing radiodiagnostic apparatus structure. The control unit is incorporated into the system's central control architecture, allowing the management functionality to be embedded without requiring a completely separate system.
Solution Approach 2:
The patent combines multiple measurement data sources (bottle content data from the contrast medium bottle, injection amount data from the automatic contrast medium injector, and imaging operation data from the radiodiagnostic apparatus) into a single integrated management system. The control unit synthesizes these multiple data streams to calculate and display the cumulative injection amount, merging previously separate tracking functions into one unified system.
2Reliability
If cumulative injection amount is monitored without real-time alerts, then system operation is simple, but excessive contrast medium use occurs
Solution Approach 1:
The control unit continuously monitors the cumulative injection amount and provides real-time feedback through display units. When the cumulative amount approaches or exceeds the reference value, the system generates alerts or warnings, creating a closed-loop feedback mechanism that allows operators to adjust injection parameters promptly to prevent excessive contrast medium administration.
Solution Approach 2:
The system performs preliminary calculations and comparisons before excessive injection occurs. By continuously comparing the cumulative injection amount against the reference value in advance, the system can issue early warnings that allow operators to take corrective action before reaching dangerous thresholds, preventing rather than merely detecting problems.
3Adaptability or versatility
If reference injection amount is set fixed, then management process is simple, but cannot adapt to different examination requirements
Solution Approach 1:
The reference injection amount is not fixed but can be dynamically adjusted based on examination requirements. The system allows the reference value to be modified according to different imaging operations, patient conditions, and clinical protocols, enabling the management system to adapt to varying examination needs while maintaining structured control through the radiodiagnostic apparatus's existing control mechanisms.

AI summary
A contrast medium injection management apparatus includes a measuring unit which repeatedly measures the injection amount of contrast medium injected from at least one contrast medium injection device into a subject to be examined, a cumulative injection amount calculating unit which repeatedly calculates a cumulative injection amount at the start of examination or after an arbitrary point of time from the injection amount, and a display unit which displays the cumulative injection amount.
