Medical Patient Validation Device Using Transaction ID Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical device assignment systems lack error-proof validation for patient and location information, leading to potential misassignments and requiring user confirmation, which is not covered by existing standards like IEC 60601-1.
Innovation Solution
A validation system using identification devices with QR codes or barcodes to read patient and location IDs, generating transaction IDs for verification, and comparing these IDs across a server and medical devices to ensure accurate assignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If logical assignment of medical devices to patients is implemented, then data transfer between server and medical devices is enabled, but assignment reliability is insufficient and requires additional user validation
Solution Approach 1:
The system implements a feedback mechanism where the medical device sends assignment data back to the server for verification. The server compares the received transaction ID with the originally generated one, and only activates the medical device when they match, ensuring reliable assignment while maintaining automated data transfer.
Solution Approach 2:
The server generates a transaction ID in advance before the actual data transfer occurs. This preliminary action allows the assignment to be pre-validated and stored, enabling subsequent automated verification without requiring real-time user intervention during critical data transfer operations.
2Adaptability or versatility
If current logical assignment methods are used, then medical devices can be assigned to patients, but error detection capability is insufficient and misrouting cannot be detected
Solution Approach 1:
The verification mechanism provides feedback by comparing the transaction ID returned by the medical device with the one generated by the server. This closed-loop verification accurately detects assignment errors and misrouting, ensuring high measurement precision while maintaining system flexibility.
3Reliability
If user validation is required for therapy orders, then assignment safety is improved, but operational time and complexity increase
Solution Approach 1:
The system performs assignment validation in advance by generating and storing transaction IDs before actual therapy delivery. This preliminary validation ensures assignment safety is established upfront, allowing subsequent operations to proceed automatically without requiring user validation time for each individual therapy order.
4Device complexity
If location information is not included in assignment data, then system complexity is reduced, but assignment completeness is insufficient
Solution Approach 1:
The transaction ID serves multiple functions: it identifies the medical device, the patient, and the location (bed/room). By encoding all assignment information into a single universal identifier, the system maintains completeness of location information while avoiding the complexity of separate tracking systems for each attribute.
