Ambulatory ECG Monitoring
Our US-based client wanted to develop a battery powered ambulatory device to obtain electrocardiogram (ECG) information from an adult patient.
Their vision was to monitor vital signs of ambulatory patients in real-time and then transmit this data via the wireless medical telemetry system frequencies used in hospitals upon arrival.
ECG information sent would need to indicate accurate readings of heart rate determination, R-wave detection, ECG filtering and arrhythmia recognition.
Indoor wireless networks within hospitals are inherently unreliable due to reflective surfaces, solid walls, beds and wards all caused interference with existing band signals.
This posed a significant challenge as complete reliability needed to be ensured. Our approach was to incorporate multiple antennas to ensure communication with tele-packs.
A new bespoke system was introduced including radios, signal processing, software and a new secure band level for our technology.
Supporting our client throughout the development cycle, from concept to end manufacture, the system provides a holistic healthcare approach by allowing multiple patient monitoring.
Approved by The Food and Drug Administration for use in the USA, one third of all US hospitals are now using this monitoring system in practice.
Based on one device per patient, the bandwidth allows for up to 189 patients to be monitored at any given time.
