one lead ECG, thermometer, pulse oximeter, and supposedly even a cuffless blood pressure sensor in one device
A number of devices now exist that turn smartphones into medical monitors, but they tend to focus on specific vital signs and you’d have to carry a number of separate components to measure a variety of parameters. A new iPhone case called Wello from Azoi Inc. is planned to be released later this year combines a one lead ECG, thermometer, pulse oximeter, and supposedly even a cuffless blood pressure sensor in one device. It will also come with an optional spirometer for measuring airway flows and volumes. Though other components are available in existing devices, cuffless blood pressure measurement is not trivial and has never been demonstrated to be as accurate as traditional cuffed BP monitors. And since FDA clearance is still required to release the Wello in the U.S., it will be interesting to see just how accurate it really is. Coincidentally, the Scanadu Scout, a device with similar claims, including cuffless blood pressure monitoring, is set to be shipped this month to all those who invested in it through an Indiegogo crowdfunding campaign.
