Telemetry System False Alarm Suppression via Location Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical telemetry systems often generate false alarms when components are removed for procedures or examinations, unnecessarily taxing hospital resources and disrupting the environment.
Innovation Solution
A telemetry system with a transmitter/monitor and receiver network that provides tracking and monitoring data, using a processor to identify false alarm regions and cancel alarms based on patient location, thereby preventing unnecessary alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If telemetry system components are removed for medical procedures or diagnostic examinations, then patient care requirements are met, but false alarms are generated that tax hospital resources and interfere with the working environment
Solution Approach 1:
The system pre-designates specific geographic locations as false alarm regions before components are removed. When a component enters these predefined regions, the system anticipates that removal may occur and suppresses alarm generation proactively, rather than reacting after an alarm is triggered
Solution Approach 2:
The processor acts as an intermediary between the monitoring system and alarm output. It receives monitoring data, determines whether the component is in a false alarm region, and selectively suppresses alarm signals based on this intermediate assessment, preventing false alarms from reaching the alarm output
2Reliability
If the telemetry system generates alarms for all alarm conditions, then patient safety monitoring is maintained, but hospital resources are unnecessarily taxed by false alarms
Solution Approach 1:
The system applies different alarm suppression characteristics to different geographic locations. Specific regions are designated with false alarm suppression properties, while other regions maintain normal alarm functionality. This localized approach preserves patient safety monitoring in most areas while eliminating false alarms in specific problem areas
3Measurement precision
If the telemetry system continuously monitors and generates alarms, then patient monitoring accuracy is maintained, but alarm fatigue occurs that interferes with the working environment
Solution Approach 1:
The system takes preliminary anti-action by suppressing alarm signals before they can contribute to alarm fatigue. By identifying false alarm regions in advance and preventing alarm generation in these zones, the system counteracts the development of alarm fatigue before it occurs, while maintaining monitoring accuracy through continued data collection
Data Source
AI summary
A telemetry system is disclosed herein. The telemetry system includes a transmitter/monitor configured to provide tracking data and monitoring data, and a receiver adapted to define a coverage area. The receiver is configured to receive the tracking data and the monitoring data from the transmitter/monitor when the transmitter/monitor is within the coverage area. The telemetry system also includes a processor configured to receive the tracking data and the monitoring data from the receiver, analyze the tracking data and the monitoring data, and identify an alarm condition based on the analysis of the tracking data and the monitoring data.
