Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chemotherapy administration errors in hospitals can have serious consequences for patient health and hospital reputation due to the administration of incorrect medical products, highlighting the need for improved control and reliability in administering medical products to individual patients.
Innovation Solution
A mobile control terminal with a barcode reader and RFID reader that compares patient-specific identification data with product-specific data stored on electronic tags to validate the correct administration of medical products, combined with a dispenser system using RFID technology for real-time tracking and validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual verification methods are used for chemotherapy administration, then the process is simple and quick, but the reliability and accuracy of patient identification and product matching deteriorates leading to administration errors
Solution Approach 1:
The patent replaces manual verification processes with automated electronic identification systems. RFID tags on containers and barcodes on patient bracelets are read by electronic readers, eliminating the need for manual checking of patient identity and product information. This substitution of mechanical/manual verification with electronic automation directly improves reliability while the portability of the terminal keeps the system manageable.
Solution Approach 2:
The system enables self-verification through automatic data comparison. The controller automatically compares the RFID data from the container with the barcode data from the patient bracelet without requiring manual intervention. The system self-validates whether the correct product is being administered to the correct patient, improving reliability through automated safety checks.
2Measurement precision
If electronic verification systems are implemented, then the accuracy of patient-product matching is improved, but the device complexity and implementation difficulty increases
Solution Approach 1:
The mobile terminal is designed as a multi-functional device that combines RFID reading, barcode scanning, data comparison, and validation capabilities in a single portable unit. This universal design allows the same device to handle multiple verification tasks (reading container RFID tags, scanning patient barcodes, comparing data, and validating matches) without requiring separate specialized equipment for each function, thereby improving measurement precision while managing device complexity.
Solution Approach 2:
The mobile terminal acts as an intermediary between the RFID reading system and the barcode scanning system. It receives data from both sources, performs the comparison, and provides the validation result. This intermediary role simplifies the overall system architecture by centralizing the verification logic in a portable device rather than requiring complex integration between separate systems.
3Ease of operation
If portable mobile terminal is used, then the ease of operation and mobility is improved, but the functionality and control capability may be reduced
Solution Approach 1:
The verification system is segmented into a portable mobile terminal for point-of-care verification and a centralized server for data management and logging. The mobile terminal handles the essential verification functions (reading RFID, scanning barcodes, comparing data) to maintain ease of operation and mobility, while the server provides additional control capabilities and adaptability for comprehensive system management. This segmentation allows the portable device to remain simple and easy to use while the overall system maintains high versatility.
