Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing injectors for parenteral solutions from multi-dose containers or large cartridges lack automatic dose restriction and microbiological usage monitoring, leading to potential overdose and prolonged use beyond safe periods, with manual documentation being error-prone and resource-intensive.
Innovation Solution
An injector system that connects to multi-dose containers or large cartridges, utilizing a data storage device (such as RFID) to track and enforce maximum individual doses and usage periods, with a processor controlling the delivery and providing warnings, and enables wireless or cable data transfer for automated documentation and integration with medical systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual documentation of product and injection parameters is used, then resource consumption is reduced, but documentation accuracy and reliability deteriorate due to human error
Solution Approach 1:
The patent replaces manual documentation (mechanical human operation) with an automated electronic data capture system using RFID technology. The reader automatically reads container identifiers and injection parameters, storing them electronically without human intervention, thereby eliminating human error while improving efficiency
Solution Approach 2:
The system enables self-service automation where the RFID reader automatically captures and stores documentation data without requiring manual input from healthcare providers. The system serves itself by automatically tracking usage and generating alerts, reducing both resource consumption and error rates
2Adaptability or versatility
If maximum filling volume restriction is not implemented in multi-dose containers, then flexibility and adaptability improve, but patient safety deteriorates due to risk of excessive dosing
Solution Approach 1:
The system implements feedback control by automatically tracking the volume of solution removed from multi-dose containers and comparing it against maximum safe dosage limits stored in the database. When the limit is approached, the system provides alerts to prevent excessive dosing, maintaining patient safety while allowing flexible container usage
Solution Approach 2:
The system performs preliminary action by pre-storing maximum dosage limits and usage parameters in the database before actual injection occurs. This allows the system to proactively monitor and control dosing throughout the container usage period, preventing overdose before it happens
3Device complexity
If usage duration monitoring is not implemented, then device complexity is reduced, but microbiological safety deteriorates due to prolonged container use
Solution Approach 1:
The system implements feedback control by continuously monitoring the duration of container usage and comparing it against manufacturer-specified time limits stored in the database. When the maximum usage duration is reached, the system automatically alerts users to stop using the container, preventing microbiological contamination while maintaining simple operation
Solution Approach 2:
The patent replaces complex manual tracking of usage duration with automated electronic monitoring through RFID technology. The system automatically captures opening time, calculates elapsed time, and provides alerts, simplifying the interface while ensuring microbiological safety
