Isansys Lifecare of Oxfordshire, UK has released a new wireless body worn ECG monitor. The LifeTouch HRV011 can record up to 100 continuous hours of breathing and heart rate, as well as QRS intervals. The device is essentially designed for single use, but the company takes back used units to reuse the electronics within.
Key physiological parameters, including heart rate, respiration rate and high resolution QRS intervals are calculated and uploaded from the LifeTouch to the secure HL7 compliant database in the Isansys Lifecare Platform – a multi layer, configurable, fully scalable, wireless patient monitoring platform.
It continuously measures and digitises the ECG signal at a rate four to five times greater than the standard required for ECG monitors thus offering unprecedented scope for a range of new analytical techniques and algorithms that can run in the HRV011 itself on the advanced ultra-low power integrated microprocessor. Current functions include heart rate, respiration rate, high-resolution QRS intervals and other heart rate variability parameters that are used, among other things, to derive the respiration rate using Isansys’ multi-parameter LifeBreath algorithm. Fundamental or derived data (or both) are sent to the web-based database where it can be stored and integrated with other patient information, or forwarded and accessed only by authorized users. Further analysis can be carried out on the data in the database to provide more information about the patient such as indicators of stress and health-warning scores and used to generate alerts or prompts regarding status of the patient.
The LifeTouch HRV011is built on the Isansys RK001 sensing platform that brings a new level of local intelligence to body worn devices by means of a new, very low power ARM Cortex based microcontroller. The wireless link uses the well-proven ANT ultra-low power wireless protocol. These inherently low power consumption components, together with efficient algorithms provide a continuous working lifetime of up to 100 hours.
