Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no effective system to track and monitor the administration of IV medications from the pharmacy to the patient, relying solely on the integrity of healthcare providers, leading to potential pilferage and medication errors.
Innovation Solution
A security system using RFID tags, barcodes, and machine vision to identify and document the administration of IV medications, ensuring the right drug is given to the right patient, with automatic recording and monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID tags, barcodes, and machine vision systems are implemented to track IV medications, then medication security and tracking accuracy are improved, but device complexity and implementation cost increase
Solution Approach 1:
The patent introduces RFID tags, barcodes, and machine vision systems as intermediary elements between the pharmacy and patient administration points. These intermediaries automatically track and verify medication movement, eliminating the need for manual monitoring while enhancing security and reducing human error in the medication chain of custody.
Solution Approach 2:
The patent replaces manual mechanical tracking methods with automated electronic and optical systems. RFID readers, barcode scanners, and machine vision cameras automatically capture and verify medication information, substituting human-based tracking with automated technological systems that provide continuous monitoring without physical contact.
2Device complexity
If manual tracking of medication administration is used, then device complexity is low, but reliability and accuracy of medication tracking deteriorate
Solution Approach 1:
The patent implements self-service tracking where the medication containers and administration equipment automatically generate, display, and verify their own identification information. RFID tags and barcodes on syringes and IV bags self-identify their contents and movement, eliminating the need for manual recording while ensuring accurate tracking throughout the medication chain.
Solution Approach 2:
The patent incorporates feedback mechanisms where machine vision systems and RFID readers continuously monitor and verify medication administration in real-time. The system provides immediate feedback on whether the correct medication is being administered to the correct patient, enabling automatic correction of any deviations from the intended protocol.
3Reliability
If automatic monitoring systems are implemented, then medication safety and patient protection are improved, but operational complexity and time requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-labeling all medication containers, syringes, and IV bags with RFID tags, barcodes, and machine vision identifiable markers before administration. This pre-preparation of identification information eliminates the need for manual verification during administration, as the system automatically reads and verifies the pre-applied identifiers, maintaining safety while simplifying the actual administration process.
