In a global culture increasingly characterized by the elimination of wires and proliferation of wireless mobility, healthcare is the next industry to benefit from these emerging technologies despite the complex nature of upgrading medical-grade patient monitors and an acceptance of the legacy systems as good enough.
To continuously measure something as simple as heart rate and blood oxygen levels — two of the core vital signs used to monitor patients suffering from numerous chronic and acute conditions — requires the patient be wired up to devices which limit independence and mobility. In the hospital there is a solution for continuously monitoring all of these parameters simultaneously, but there is no long-term, mobile and comfortable continuous monitoring solution for the home.
Many consider the wrist to be the premiere location to conduct any sort of wearable monitoring because of the familiarity most patients already have with wearing watches on their wrists. Dozens of startups are developing wrist-worn activity monitors, but very few offer medical grade monitoring of three key vital signs — pulse oximetry, heart rate and respiratory rate.
The Oxitone watch is a wrist-worn, medical-grade pulse oximeter which eliminates the need for an ‘crocodile clip’ fingertip sensor and thereby continuously measuring oxygen saturation (SpO2), heart rate and respiratory rate wirelessly and entirely at the wrist. Unlike the hospital-based continuous health monitors the Oxitone device has an ergonomic and attractive watch-like design, making it wearable, inexpensive and reliable throughout the patient’s daily activity. The Oxitone watch offers patients and clinicians a significant value proposition by enabling non-invasive, remote patient monitoring with real-time two-way biofeedback.
The Oxitone watch uses photoplethysmography to capture SpO2 measurements in this novel way, disrupting the legacy patient monitoring markets, which are dominated by bulky, fully wired and invasive devices that must be clipped to the patient’s fingertip at all times.
Oxitone’s goal is to provide the utmost home monitoring platform. This includes displaying the pulse oximetry and pulse rate information on the device screen in real time. A Bluetooth-connected application obtains and analyzes the information and alerts the treating physician or medical call center to emergency situations. A dashboard application highlights trends in the patient’s daily health profile which is being continuously uploaded to the cloud and filed with her personal health records. The information can be securely shared by the patient in a convenient and timely manner.
