PORTLAND, Ore.—As medical sensors monitoring both people and their environment proliferate, Freescale Semiconductor Inc. aims to reintegrate them with a home health hub (HHH) reference design that handles all popular wired and wireless protocols—a kind of universal router for connecting cloud computers to home health care.
At the Medica conference this week in Dusseldorf, Germany, Freescale will describe how its HHH integrates Wi-Fi, Ethernet, USB, Bluetooth and ZigBee into a single router that connects medical sensors (inputs), to tablet displays (outputs), to medical analytics in the clouds (processing) and to doctors advise online.
The HHH aggregates medical monitoring devices—such as blood pressure monitors, blood glucometers, weight scales, pulse oximeters and similar—for cloud computers which can store the data for display to doctors, as well as run analytics the results of which can be displayed directly on the patient's on their tablet display, such as advising an insulin injection to a diabetic from a glucose reading. The HHH's intelligent iMX-28 processor—based on an ARM-9 core— can also communicate sensor readings directly to tablets for display as well as securely share health data with service providers.
"The World Health Organization claims there are hundreds of millions of chronic disease patients worldwide—over 75 percent of our healthcare spending," said Steven Dean, Freescale’s Global Healthcare segment leader. "Remote patient monitoring devices based on Freescale's home health hub can cut health care costs by allowing patients to remain at home, as well as provide peace of mind for family members."
The HHH is compatible with Continua medical devices including blood pressure monitors, pulse oximeters and weight scales. It is also compatible with Microsoft's HealthVault cloud computer service which can log medical data to secure online repositories that lets users organize, store and share health information with their doctors. The HHH also includes a "panic button" capability that uses a sub-1 GHz radio to activate a personal emergency response system (PERS) with the HHH.
The HHH is software is compatible with Android, Linux, Windows Embeded Compact 7, and QNX's Neutrino realtime operating system (RTOS) on the i.MX-53 Sabre tablet platform.
