British medical services startup Isansys Lifecare Ltd has released what it says is the world's first commercially available, clinical-grade, wireless cardiac monitor to support low-cost continuous ECG heart monitoring.
By making the most costly elements of the Isansys LifeTouch HRV011 ECG wireless monitor recyclable, its application cost can fall (with repeated usage) to just a few tens of cents.
In operation, the HRV011 resembles a lightweight bandage strip that adheres to a patient's body and analyses the ECG signal of every heartbeat in 4-5 times more detail than that required for a wired ECG monitor. From this data, a proprietary algorithm running within an on-board ARM Cortex-based microcontroller is used to calculate key physiological parameters – including respiration rate and R-to-R peak intervals – to detect problems rapidly. Redundancy is also built in because collected data is securely transmitted to a web-based HL7-compliant database.
The performance of the Nordic nRF24AP2 ANT chip and use of the ultra-low power ANT wireless protocol help enable the LifeTouch HRV011 to achieve a battery operating life of up to 100 hours from a regular CR2032 coin cell battery under continuous usage conditions, while offering high-interference immunity in even the most challenging (active Bluetooth and Wi-Fi) 2.4GHz RF operating environments.
