Medical Data Transfer via Metadata-Guided Removable Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical devices often cannot be directly connected to the Internet, and when restricted to local networks for security, transferring medical data to remote servers is inefficient and insecure, requiring complex user interfaces and manual management.
Innovation Solution
A medical device tracks transfer statuses of data and uses metadata files on a removable storage device to automatically determine which data to transfer, reducing user intervention and enhancing security and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual data transfer management is implemented, then data transfer can be performed, but user interface complexity increases and user error risk increases
Solution Approach 1:
The system automatically tracks transfer statuses of medical data and uses metadata files on removable storage devices to determine which data needs to be transferred. The medical device autonomously manages the data transfer process without requiring user selection or intervention, thereby simplifying the user interface while maintaining effective data transfer management.
2Productivity
If automated data transfer status tracking is implemented, then transfer efficiency improves and redundant transfers are prevented, but system complexity increases
Solution Approach 1:
The system implements automatic tracking of data transfer statuses and uses feedback from metadata files on removable storage devices to determine which medical data needs to be transferred. This feedback mechanism prevents redundant transfers of already-transferred data and enables efficient automated management of data transfer operations.
3Reliability
If security restrictions are applied to medical devices, then patient data security improves, but data transfer capability to remote servers deteriorates
Solution Approach 1:
The system uses removable storage devices as intermediary carriers to transfer medical data from secured medical devices to remote servers. The medical device maintains security restrictions and does not directly connect to external networks, while the removable storage device serves as a secure intermediary that can be physically connected to both the medical device and external computing systems for data transfer.
Data Source
AI summary
A method for transferring medical data from a medical device to a remote server includes, at the medical device, tracking a transfer status of medical data stored on a local storage. The stored medical data includes first medical data having a first status and second medical data having a second status. The medical device is physically coupled to a removable data storage device including one or more metadata files. The medical device determines what data is to be transferred to the removable data storage device based on the one or more metadata files and initiates a data transfer process to transfer at least a portion of the first medical data to the removable data storage device based on information determined from reading the one or more metadata files. After completing the data transfer process, the medical device updates the transfer status of the portion of the first medical data.
