脉搏血氧计是一种流行的监测动脉血氧饱和度 (SPO2) 的仪器。虽然目前市场上主流的是指尖式脉搏血氧仪，但对于长期监测，尤其是运动监测，仍然不方便。因此，开发可穿戴式脉搏血氧仪，例如指座式脉搏血氧仪，可以有效解决上述问题。然而，指根的组织结构复杂，并且缺乏光源和探测器放置对测量SPO2的影响的详细信息。在本研究中，通过光学人体组织模拟研究了具有多探测器的环形脉搏血氧计的实用性。讨论了能够提供最佳 SPO2 测量效率的环形脉搏血氧计的优化设计。还讨论了具有单检测器和多检测器的环形脉搏血氧计的效率。最后，还实现了可穿戴式无线环式脉搏血氧计来验证仿真结果，并与商用指尖式脉搏血氧计进行比较。
The pulse oximeter is a popular instrument to monitor the arterial oxygen saturation (SPO2). Although a fingertip-type pulse oximeter is the mainstream one on the market at present, it is still inconvenient for long-term monitoring, in particular, with respect to motion. Therefore, the development of a wearable pulse oximeter, such as a finger base-type pulse oximeter, can effectively solve the above issue. However, the tissue structure of the finger base is complex, and there is lack of detailed information on the effect of the light source and detector placement on measuring SPO2. In this study, the practicability of a ring-type pulse oximeter with a multi-detector was investigated by optical human tissue simulation. The optimal design of a ring-type pulse oximeter that can provide the best efficiency of measuring SPO2 was discussed. The efficiency of ring-type pulse oximeters with a single detector and a multi-detector was also discussed. Finally, a wearable and wireless ring-type pulse oximeter was also implemented to validate the simulation results and was compared with the commercial fingertip-type pulse oximeter.
