Bedside Station Backup for Nurse Call Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nurse call systems in hospitals are prone to malfunction when the server is down or network connection is unstable, potentially leaving patients unable to call for help effectively.
Innovation Solution
An emergency call apparatus and system where a bedside station, powered by a gas supply system, backs up connection information of target devices and establishes emergency call connections independently if the network connection with the managing server is disconnected, ensuring continuous functionality and data storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the nurse call system operates through a managing server and network connection, then the system can be centrally managed and controlled, but the system reliability deteriorates when the server is down or network connection is unstable
Solution Approach 1:
The bedside station performs preliminary actions by backing up connection information of target devices locally before network failures occur. This allows the station to independently establish emergency call connections without relying on the managing server, thus resolving the contradiction between centralized management and system reliability.
Solution Approach 2:
The system is segmented into independent functional units: the bedside station can operate autonomously for emergency calls while the managing server handles centralized management tasks. This segmentation allows the emergency call function to remain reliable even when the server is unavailable, addressing the contradiction between centralized control and system reliability.
2Reliability
If the bedside station stores connection information locally, then the emergency call reliability improves when network is disconnected, but the device complexity increases
Solution Approach 1:
The bedside station creates a simplified copy of the connection information from the managing server and stores it locally. This copying approach enables reliable emergency calls without complex distributed database systems, resolving the contradiction between reliability and device complexity by using a simple local storage solution rather than a complex redundant system.
3Reliability
If the bedside station independently establishes emergency call connections, then the system reliability improves during network outages, but the loss of information increases without centralized server coordination
Solution Approach 1:
The bedside station performs preliminary backup of connection information before network failures occur. This preliminary action ensures that critical data is preserved locally, preventing information loss during outages while maintaining the ability to synchronize with the server when connectivity is restored.
Solution Approach 2:
The system implements feedback mechanisms where the bedside station can report emergency call data and patient monitoring data back to the managing server when network connectivity is restored. This feedback loop minimizes information loss by ensuring data synchronization occurs as soon as the network becomes available again.
Data Source
AI summary
An emergency call apparatus, an emergency call system and a backup method thereof are provided. The emergency call system includes a bedside station, a managing server and at least one target device. In the method, the bedside station detects a triggering signal of an emergency call and then detects a network connection with the managing server. In response to detecting the network connection is connected, the bedside station transmits a request of the emergency call to the managing server and establishes an emergency call connection with the at least one target device according to connection information of the at least one target device stored in the managing server. In response to detecting the network connection is disconnected, the bedside station establishes the emergency call connection with the target device according to a backup of the connection information of the target device stored in the bedside station.
