A noninvasive device for simultaneous monitoring arterial and venous blood oxygenation and its test in vacuum-based cupping therapy

A portable and noninvasive blood oxygenation device that uses light-emitting diodes and three-wavelength near spectroscopy has been developed The device is compact enough to be portable and it is therefore expected to make better use of the advantages of NIRS-based oximetry and to expand the scope of applications of monitoring blood oxygenation. The algorithm for the device was mentioned briefly. From evaluation tests of the algorithm applied to in vitro measurements, it was confirmed that a good linear response to the concentration of oxygenated and deoxygenated arterial and venous blood In vivo measurements, we nwnitored the blood oxygenation in the cupping therapy, and the results turned out the device to have a good performance. The cupping therapy indeed can mobilize blood flow effectively.
