Taiwan Biophotonic receives CE Mark for heart rate and blood oxygen monitoring smart watch

March 6, 2017
Medical wearables firm Taiwan Biophotonic Co. (tBPC) recently announced the CE Marking and the debut of the industry’s first finger-free wrist pulse oximeter, the oCareTM Pro 100.

tBPC’s wrist pulse oximeter, the oCareTM Pro 100, provides a non-invasive method to measure and record heart rate and blood oxygen saturation on the wrist without wires or a fingertip clamp. This device is designed to follow adult users for use in checking and/or recording of specific physiological parameters. Such users may be in hospitals, hospital-type facilities, or a home environment. Professional users can upload timely data measured during daily activities or sleeping for physical or clinical evaluation.

Pulse oximeters have been recognized as life-saving devices for patients with chronic respiratory disease such as OSA, COPD, CHF and asthma. OSA patients with breathing problems during sleep may encounter life-threatening situations at low blood oxygen levels. Conventional pulse oximeters use a clip-like probe that measures the heart rate and blood oxygen level from the fingertip, making it inconvenient and painful for continuous monitoring.

tBPC’s oCareTM Pro 100 is built with a DOE Lens Reflective PPG Sensor (oCareTM Sensor) mounted on the bottom of watchcase, making its application site the wrist skin. The sensor consists of two or more light emitting diodes (LEDs) and one or more photodiode light detectors (PDs) located side-by-side on a substrate. Light beams are shone from LEDs through the skin to the arteriolar bed of the tissue. The arteriolar bed absorbs variable amounts of light during the pulsations. Changes in light absorption during the pulsing cycle are measured by the PDs as scattered light that is reflected back from the pulsating arteriolar bed. The ratio of light absorbed is translated into a measurement of heart rate and functional oxygen saturation.
