Innovation with proven results
Healthcare providers need the highest possible accuracy to monitor patients’ key vital signs. But the current oximeter devices are only accurate when patients are motionless. And variations in skin coloration, tattoos and nail polish pose further challenges for traditional pulse oximeters.
Medtor’s FDA cleared SafeSAT® technology provides a breakthrough in vital signs monitoring. The patented spectral sensor technology delivers the most accurate heart rate and blood oxygen readings available, filtering out movement and other interfering factors, such as skin tone.
Medtor’s technology produces two separate and independent data streams that provide enhanced precision and accuracy. One data stream is based on two-wavelength illumination, and the other reveals precise tissue properties from spectral white light absorption—an innovation in precision and accuracy.
Medtor’s two data streams are processed by a proprietary algorithm to derive stable composite data for blood oxygenation and heart rate.
The small hardware footprint of the SafeSAT® sensor can be packaged in a variety of ways, giving hardware makers the flexibility needed to make products as compact as possible with no sacrifice in accuracy.
The SafeSAT® technology provides stable and accurate Heart Rate data, even on highly active subjects and under conditions where current optical sensors are unable to provide meaningful or accurate information.
SafeSAT® sensor power consumption is minimal by design, which allows sensor packaging into fitness trackers, smart watches, and other mobile electronics. The sensor can monitor vital signs throughout the day with minimal battery drain.
Our SafeSAT® technology is protected by several issued and pending patents, granted worldwide. We continue to expand the features of our technology platform and expect further innovations protect in new patent filings.

Skin pigmentation light to dark
2 SafeSAT® Oximeters with finger clip sensors, one on each hand were able to acquire both red/ir and white SpO2 data for all subjects for the full saturation range
Both red/ir and white-based SpO2 data follow well defined transfer functions with respect to the reference oximeter used by Clinimark with ARMS value of 2.56 for the entire saturation range from 99% to 70%
Both SafeSAT® systems were able to acquire accurate data on all study subjects, independent of skin type
Study validates the ability of the SafeSAT® oximeter technology to provide a parallel white LED based SpO2 data stream leveraging the proprietary spectral sensor technology

Skin pigmentation light to dark
The wrist sensor delivered white LED derived values with ARMS of 1.9% SpO2 over the full saturation range
The finger clip sensor connected to the SafeSAT® oximeter white-LED derived saturation data delivered values with an ARMS of 3.2% SpO2 between 70% and 100% saturation compared to the Covidien oximeter
Our SafeSAT® sensors (both reflectance and transmissive) and proprietary algorithm have been evaluated in several independent clinical studies referenced both to transfer standard oximeters and blood gas based reference data. Our sensors and hardware were able to produce results that reduced absolute errors more than three-fold and root mean standard deviations more than two-fold when referenced to current state-of-the-art clinical sensors and oximeters.

Greatly enhanced real-time stability of SpO2 and read-through motion ability of SafeSAT® finger and wrist reflective sensors
Compared to Covidien Max adhesive finger sensors, SafeSAT® non-adhesive finger sensor performs with 3x greater motion tolerance
Compared to adhesive MaxFact Forehead sensor, the SafeSAT® non-adhesive wrist sensor still provides a 30% reduction in STDEV of oxygen saturation data
The SafeSAT® Oximeter effectively filters out motion artifacts in both finger and wrist site when compared to Covidien adhesive finger and forehead sensors placed on the same subject
