Masimo announced the launch of its Radius Tº™ Continuous Thermometer for consumers. Unlike spot-check, episodic thermometers, the wearable, wireless Radius Tº measures body temperature continuously and transmits data and customizable temperature notifications to the user’s smartphone, thus helping to monitor temperature during sleep, reports BusinessWire. The thermometer can be used by anyone from children to elderly adults.

Joe Kiani, Founder and CEO of Masimo, said, “We’re excited to expand our growing line of consumer solutions, which includes MightySat and Masimo Sleep, with the Radius Tº Continuous Thermometer. For years, clinicians have trusted Masimo technology to monitor patients in the hospital. With Radius Tº and our other consumer solutions, we’re bringing our expertise and experience in accurately and reliably measuring physiological data from the hospital to the home.”

Radius Tº eliminates manual measurements while providing continuous insight into changes in the user’s temperature. In addition, Radius Tº uses proprietary algorithms to provide body temperature measurements for users five years or older that approximate oral temperature, not just external skin temperature. Radius Tº provides temperature measurements with laboratory accuracy within ±0.1ºC, whereas other oral thermometry solutions typically have laboratory accuracy within ±0.2ºC.

Earlier this year, Masimo launched Radius Tº as part of the Masimo SafetyNet™ remote patient management solution, for use both in hospitals and by patients at home. Dr. Neal Fleming, M.D., Ph.D., Vice-Chair for Education in the Department of Anesthesiology and Pain Medicine at UC Davis Health, commenting on his experience using Radius Tº, said, “Radius Tº is noninvasive and convenient for patients. I do not have to interrupt their daily activities or their sleep and it provides me continuous trend data that is a powerful guide to patient care. It makes it easier for me to recognize possible changes in their symptoms.”

The disposable Radius Tº sensor is flexible and slim, and can be worn comfortably for up to eight days, and is water-resistant during shower and exercise. Users are free to carry on with their daily activities and sleep, without interruption or hassle – all while Radius Tº continuously collects temperature data. Using built-in Bluetooth®, the sensor easily pairs with the Masimo Radius Tº App on the user’s smartphone.

Radius Tº isn’t FDA 510(k) cleared yet. The device is marketed under the FDA’s Enforcement Policy for Clinical Electronic Thermometers During COVID-19. Radius Tº is CE marked for use in Europe.
