Medical Information Management With Physically Separated Databases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical devices face challenges in managing massive medical data effectively and securely due to limited storage capacity and the need for costly updates, which often require updating the entire device.
Innovation Solution
A system with physically separated databases allows authenticated terminal devices to access and manage medical information and application programs through a cloud-based platform, enhancing security and efficiency by reducing the need for device-wide updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If medical data is stored in the medical device by which the medical data is generated, then the medical data can be stored locally and accessed quickly, but the storage capacity is limited and requires costly device-wide updates
Solution Approach 1:
The system divides the storage function from the medical device by introducing a separate server for data storage. The medical device generates and transmits data, while the server stores and manages the massive medical data, allowing independent scaling of storage capacity without affecting the medical device structure
Solution Approach 2:
The system introduces a terminal device as an intermediary between the medical device and the server. The terminal device retrieves data from the server and presents it to users, separating the storage function from both the medical device and direct user access, enabling flexible updates without device-wide modifications
2Ease of operation
If medical data is stored in the medical device, then data access is straightforward, but managing massive medical data effectively and securely becomes difficult
Solution Approach 1:
The terminal device serves as an intermediary that handles data retrieval from the server and presentation to users. This separates security management (server) from user interaction (terminal), allowing secure centralized storage while maintaining simple user access through the terminal interface
Solution Approach 2:
The system extracts the data management and security functions from the medical device and concentrates them in the server. The server implements authentication, authorization, and secure storage, while the medical device focuses solely on data generation, improving both security and operational simplicity
3Reliability
If the whole medical device is updated to update medical data and/or application(s), then all data and applications are updated, but it costs a great quantity of manpower and material resource
Solution Approach 1:
The system segments the update process by separating application updates from data updates. Application programs are stored and updated on the server independently from the medical device, allowing selective updates of specific applications or data without requiring complete device reupdates, significantly improving update efficiency
Solution Approach 2:
The system uses copying by storing application programs and data on the server and transmitting only necessary copies to the terminal device or medical device. Updates are applied to the server copy, and subsequent accesses retrieve the updated version, avoiding the need to update every device instance individually

AI summary
The present disclosure provides systems and methods for managing medical information. A method may include obtaining, from a terminal device, an access request regarding target information; determining whether the terminal device is authenticated; in response to determining that the terminal device is authenticated, identifying, from a plurality of databases, a target database based on the access request, wherein the plurality of databases are physically separated from each other; obtaining the target information by accessing the target database; and transmitting the target information to the terminal device.
