Fluid Injector Compliance Monitoring via Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid injector systems face challenges in providing effective feedback to users about compliance with usage instructions for disposable components, leading to potential misuse, contamination, and safety risks.
Innovation Solution
A fluid injector system equipped with a display and control device that monitors and provides visual feedback on compliance with usage instructions through a compliance report, indicating whether disposable components were used in accordance with instructions for each injection protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual feedback and compliance reporting features are added to the fluid injector system, then user compliance with usage instructions is improved, but device complexity increases
Solution Approach 1:
The system implements visual feedback mechanisms including display screens that show compliance status, icons indicating proper or improper use, and auditory alerts that notify users of compliance violations. This feedback loop continuously monitors disposable component usage and provides real-time guidance to users, improving compliance without requiring complex manual tracking procedures
Solution Approach 2:
The system automatically tracks and monitors disposable component usage through integrated sensors and control circuits that detect installation, removal, and usage patterns. The compliance reporting system generates reports autonomously without requiring manual intervention, and the system self-adjusts to provide context-appropriate feedback, reducing the operational burden on users while maintaining high compliance monitoring capability
2Object-affected harmful factors
If the system provides detailed compliance monitoring and reporting, then hygiene safety is improved, but ease of operation deteriorates
Solution Approach 1:
The system introduces an intermediary compliance monitoring layer that sits between the user and the disposable components. This intermediary automatically tracks usage patterns, compares them against predefined hygiene protocols, and provides guidance through user-friendly interfaces. The intermediary handles the complexity of compliance verification while presenting simple visual cues to users, maintaining ease of operation while ensuring hygiene safety
Solution Approach 2:
The system employs color-coded visual indicators including green icons for compliant usage, red icons for non-compliant usage, and yellow warnings for approaching compliance limits. These color changes provide immediate, intuitive feedback to users about compliance status without requiring complex displays or difficult-to-interpret data, maintaining operational simplicity while effectively communicating hygiene requirements
3Measurement precision
If the system tracks compliance for each injection protocol, then measurement precision of compliance status is improved, but loss of time for data processing increases
Solution Approach 1:
The system pre-loads compliance criteria, usage protocols, and evaluation rules into its control circuitry before operation begins. Disposable component specifications and compliance thresholds are predetermined and stored in memory. When usage events occur, the system compares them against these pre-established criteria rather than performing complex real-time analysis, achieving high measurement precision with minimal processing time
Solution Approach 2:
The compliance tracking system divides monitoring into discrete segments corresponding to individual injection protocols, disposable components, and usage events. Each segment is tracked independently with its own compliance status, allowing the system to process and report on specific protocols without being burdened by aggregate data from all protocols. This segmentation enables precise compliance measurement while maintaining efficient data processing through modular, event-driven architecture

AI summary
A fluid injector system for use in administering to a patient a fluid in an injection protocol in connection with a diagnostic imaging procedure includes at least one display and a control device. The control device is programmed to determine, for each of the injection protocols performed by the fluid injector system, a component status for the at least one disposable component. The component status indicates whether use of the at least one disposable component was compliant with instructions for use applicable to the at least one disposable component. The control device is further programmed to enable the at least one display to display a compliance report. The compliance report includes one or more visual indicators providing visual feedback about compliance with the instructions for use based on the component status determined for each of the injection protocols performed using the fluid injector system.
