Taiwan Medical photoelectric launched the world's first set of finger tip probe without the need to set the oxygen saturation meter

From 2014 onwards, a large number of healthy sports wearable device pushed out of the city, whether it is a watch or bracelet, or other types of design, mostly imported health motion sensing function, are guaranteed to measure movement, sleep, heart rate, blood oxygen and other functions. At present, the wearable device is mainly based on the healthy movement function, and toward the home care market, heartbeat, blood oxygen, blood pressure, blood sugar and other devices can detect the indicators obtained are different. Among them, the blood oxygen saturation meter is mainly through the red light and infrared light to detect the subcutaneous tissue of the artery microvascular blood volume changes due to cardiac contraction and detection of oxygen concentration. The market demand is mainly for patients with respiratory diseases such as asthma, obstructive pulmonary disease, sleep apnea and so on. LEDinside through the opportunity to interview with Chen Zhicheng, general manager of the Department of medical products to share the market demand and trends in the wearable oximeter market.

With the emergence of various types of wearable devices on the market, it is expected that wearable medical devices will also come with the development of a variety of related technologies. The key technologies of wearable medical devices include: biomedical sensors, high density batteries, low power consumption control module, waterproof and anti knock function, and user habits, the future market demand remains to be seen. From the perspective of medical photoelectric, active in the design and development of optical sensing, continue to pave the way for the development of this market.

Measurement of optical oxygen saturation meter, comprising a light transmission method for fingertip and light reflection method for finger and wrist. Oxygen saturation of international well-known medical equipment manufacturers, although there are wrist pulse oximeter, but still need a wired connection through the sensor probe to wear on the fingertips, but caused by the measurement of the sick and the fingertip for peripheral nerve data accuracy and responsiveness are still to be improved.

The wrist oximeter currently on the market can not be on the wrist position at the same time measurement of heart rate and oxygen saturation, because the main oxygen saturation signal strength of wrist position (SNR) significantly less than the signal strength of fingertip position. The signal intensity and increase the accuracy of product is currently the main target of wrist pulse oximeter product development, the main direction is to improve the signal and noise reduction. However, most manufacturers only through increasing the input current of the LED, or expand the light sensor (PhotoDiode) of the light receiving area, enhance the receiving function, not only the sensor power consumption, at the same time, will enhance the temperature sensor, and the sensor contact may cause skin burns.

Taiwan Medical optoelectronics is about to launch the world's first wristband oxygen saturation meter oCarePro100, do not need to wear the forehead of the wired finger probe, can be measured directly at the wrist position and blood oxygen saturation. The use of its own R & D and manufacture of reflective optical sensor, sensor contains a special micro structure design, can greatly improve the sensor to clutter ratio. Product features are not worn at the fingertips, you can avoid the discomfort caused by measurement and enhance the accuracy. Through the actual measurement, wrist oximeter can provide accurate measurement of rapid response.
