Ventilator Telemonitoring With Server-Terminated Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern ventilators continuously transmit data to servers for telemonitoring, leading to unnecessary energy consumption, mobile data charges, and privacy concerns, despite not requiring constant data exchange.
Innovation Solution
A method and system where the ventilator terminates data transmission upon request from the server, establishes connections at predefined intervals, and only transmits data when requested, reducing unnecessary data transfer and conserving energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ventilator is constantly connected to the server for telemonitoring, then remote monitoring capability is improved, but energy consumption increases and data privacy is compromised
Solution Approach 1:
The system implements periodic data transmission instead of continuous connection. The ventilator establishes temporary data transmissions at scheduled intervals or upon specific events (alarm conditions, therapy changes), then terminates connections when not needed. This periodic action maintains monitoring capability while significantly reducing energy consumption compared to constant connectivity.
2Reliability
If the ventilator is constantly connected to the server for telemonitoring, then remote monitoring capability is improved, but data privacy is compromised
Solution Approach 1:
By implementing periodic rather than continuous data transmission, the system limits the windows of vulnerability where data is exposed during transmission. The temporary nature of connections reduces the opportunity for unauthorized access and interception, thereby protecting data privacy while maintaining essential monitoring functions.
Solution Approach 2:
The system extracts and transmits only necessary medical data during temporary connections, rather than continuously streaming all data types. This selective data extraction minimizes the amount of sensitive information exposed during each connection event, reducing privacy risks while maintaining monitoring effectiveness.
3Reliability
If the ventilator is constantly connected to the server, then telemonitoring is enabled, but mobile data charges increase
Solution Approach 1:
The system uses periodic data transmissions at scheduled intervals or triggered by specific events rather than maintaining constant mobile data connections. This approach enables telemonitoring functionality while dramatically reducing mobile data consumption, eliminating unnecessary charges associated with continuous connectivity.
4Use of energy by moving object
If data transmission is terminated by the server, then energy consumption is reduced, but the ventilator cannot independently initiate transmissions
Solution Approach 1:
The system implements a feedback mechanism where the server monitors incoming data and sends termination commands when transmission is no longer necessary. This feedback loop allows the ventilator to maintain the capability to initiate transmissions when needed (such as during alarm conditions or therapy changes) while the server controls the termination to optimize energy consumption. The ventilator responds to server commands while retaining autonomous initiation capability for critical events.
