Medical Device Monitoring Data Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical devices face challenges in managing monitoring data storage, as they have limited space and existing methods require deleting older data to store new data, potentially leading to the loss of important historical information.
Innovation Solution
A method and device that allow operators to selectively lock and delete monitoring data based on predefined rules, ensuring critical data is retained while freeing up storage space by automatically deleting unlocked data when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If monitoring data is stored continuously in the monitor and central station, then the amount of stored data increases, but the storage space becomes insufficient
Solution Approach 1:
The patent changes the state of data from unlocked to locked, creating a binary classification that determines deletion eligibility. This parameter change (locked/unlocked status) allows the system to differentiate between data that should be retained and data that can be deleted, resolving the contradiction between storing more data and limited storage space
Solution Approach 2:
The patent segments the monitoring data into two distinct groups: locked data and unlocked data. This segmentation allows selective management where locked data is protected from deletion while unlocked data can be deleted to free up storage space, enabling the system to maintain both large data quantities and manageable storage utilization
2Volume of stationary object
If old data is deleted to free up storage space, then storage capacity is maintained, but important historical data is lost
Solution Approach 1:
The patent applies preliminary action by locking important data before storage space becomes critical. By pre-identifying and locking data that should be retained, the system prevents accidental deletion of important historical information while still allowing deletion of unlocked data when storage capacity is insufficient
Solution Approach 2:
The patent implements feedback through the locking mechanism where operators can review and selectively lock data based on its importance. This feedback loop ensures that data deletion decisions are informed and controlled, preventing loss of important historical data while maintaining storage capacity
3Reliability
If all monitoring data is retained without deletion, then data integrity is maintained, but storage space is exhausted
Solution Approach 1:
The patent applies local quality by differentiating the protection status of different data segments. Instead of uniformly protecting or deleting all data, the system applies locked status to specific data portions that require preservation, while allowing deletion of unlocked data, thus maintaining data integrity for critical information while managing storage space

AI summary
Disclosed are a medical device and a data management method therefor. The data management method includes: receiving an instruction for selecting a locking rule to determine a target locking rule, wherein the target locking rule is used for screening monitoring data so as to carry out locking; under the trigger of a first trigger condition, screening the monitoring data according to the target locking rule, and locking the screened monitoring data; and under the trigger of a second trigger condition, selectively deleting monitoring data that is not locked. An operator can selectively lock the monitoring data by selecting the locking rule, thereby avoiding the deletion of monitoring data needing to be retained, and facilitating the management of the monitoring data.
