Masimo Launches Radius Tº Continuous Thermometer

Masimo announced the launch of the Radius Tº Continuous Thermometer for consumers. Unlike spot-check, episodic thermometers, the wearable, wireless Radius Tº measures body temperature continuously, seamlessly transmitting data and customizable temperature notifications to the user’s smartphone—helping caregivers, such as parents, monitor loved ones’ temperatures even while they sleep.
 
Radius Tº represents a paradigm shift in thermometry by making it continuous, wearable, and hassle-free. Traditional periodic and invasive methods depend on the user repeatedly conducting a series of steps that can interrupt daily activities, including sleep, and can miss body temperature trends and patterns. With a traditional thermometer, a person may only notice a spike in temperature hours after a spike has occurred, or may not even become aware of it if it is during sleep. By contrast, Radius Tº continuously and seamlessly measures temperatures using a small, inconspicuous, wearable sensor that can be easily applied to anyone from children to elderly adults—with no action needed after initial application to the skin. Radius Tº eliminates manual measurements while providing continuous insight into changes in the user’s temperature and helps users understand which way their temperature is trending. 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.”
 
Flexible and slim, each disposable Radius Tº sensor 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, providing real-time temperature values with user-definable automatic notifications (for example, when temperature exceeds a certain user-selected threshold or if it spikes), as well as detailed historical trending data, revealing the baseline and fluctuation patterns unique to each person that can help users determine whether a rise in temperature warrants action. In addition, the user-friendly Masimo Radius Tº App can support multiple family member profiles and can be easily set to schedule medication reminders.
 
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 is not FDA 510(k) cleared. The device is marketed under the FDA’s Enforcement Policy for Clinical Electronic Thermometers During COVID-19. Radius Tº is CE marked.
