A pulse oximeter is a noninvasive instrument used in clinical medicine to monitor arterial oxygen saturation. Fingertip-type pulse oximeters are popular, but their inconvenience for long-term monitoring in daily life means that other types of wearable pulse oximeters, such as a ring-type reflection pulse oximeter, needs to be developed. However, designing a ring-type pulse oximeter for measuring the oxygen saturation is difficult due to the complex tissue architecture of the finger base. This study used human tissue simulations to evaluate the practicability of a ring-type reflection pulse oximeter design. Moreover, given that the collection of diffusely reflected light can be enhanced by using a parabolic reflector, the efficacy of a ring-type reflection pulse oximeter with a parabolic reflector was also evaluated.
