Infusion Pump RFID Optical Imaging Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infusion pumps often result in adverse drug events due to incorrect programming by medical staff, lacking the ability to independently verify appropriateness of manual settings, and there is no direct link between the patient and the medication being administered.
Innovation Solution
Integration of an optical imaging and RFID reading module with an infusion pump, allowing for automatic data input and verification through a microcontroller that interconnects optical image capture and RFID subsystems, enabling barcode reading and RFID interrogation to ensure accurate drug delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual programming is used to set infusion rate and volume, then the pump can be configured for specific patient needs, but errors occur due to incorrect settings by medical staff
Solution Approach 1:
The system enables self-verification by automatically scanning patient identifiers and medication labels to confirm that the programmed settings match the actual patient and medication information, allowing the system to verify its own configuration without requiring additional manual checking
Solution Approach 2:
The system provides real-time feedback to medical staff by displaying scanned patient and medication information on the pump display, allowing immediate verification and correction of any programming errors before infusion begins
2Productivity
If smart infusion pumps with hospital databases are integrated, then data can be automatically retrieved, but extensive programming with profiles is required prior to use
Solution Approach 1:
The system extracts and stores only the essential patient and medication identification data locally in the pump's memory, eliminating the need for complex hospital database profiles while maintaining the ability to verify infusion parameters
Solution Approach 2:
The pump is designed with universal scanning capabilities that can read various patient identifiers and medication labels, making it adaptable to different hospital systems without requiring facility-specific programming profiles
3Device complexity
If there is no link between patient and medication at the bedside, then the pump structure remains simple, but verification of appropriate drug delivery cannot be performed
Solution Approach 1:
The system merges optical scanning, RFID reading, and infusion control functions into a single integrated pump unit, creating a direct link between patient identification, medication verification, and drug delivery without requiring separate external devices

AI summary
An infusion pump including an optical imaging and an RFID reading module connected thereto through a host interface. The optical imaging and RFID module comprises a system microcontroller that interconnects an optical image capture subsystem and an RFID subsystem preferably routed through a single interface to the infusion pump. This infusion pump controls operation of the optical imaging and RFID module through commands provided through the interface and, as a result, capable of obtaining data encoded on barcodes and RFID tags. The infusion pump, through the optical imaging and RFID module, may thus automatically retrieve patient data, pharmacological information, dosage amounts, etc. from barcodes or RFID tags applied to the patient, intravenous medication, and even medical staff.
