Taiwan Biophotonic Co (tBPC) has received CE marking and the debut of the industry’s first finger-free wrist pulse oximeter, the oCare Pro 100.

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

The company’s oCare Pro 100 is a medical smart watch, built with a DOE Lens Reflective PPG sensor (oCare 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 sidebyside 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.

“Our oCare Sensor has high lighting efficiency and less power consumption than most common reflective PPG sensors, LED, and photodiode components in the market,” says JC Chen, PhD, founder and president of tBPC. “In the oCare Sensor, each LED die is separately encapsulated with a cannonballshaped lens, and the photodiode is covered by an encapsulated layer with DOE (micro-structure) surface. These lenses will enhance the LED output radiant flux by more than 50-100%. The DOE will enhance the photodiode sensitivity by more than 10-50%.”
