| Popis: | 102 Pulse oximeter is a popular instrument to monitor the arterial oxygen saturation (SPO2). Although fingertip-type pulse oximeter is the marketing mainstream at present, it is still inconvenient for long-term monitoring, in particular, under motion. Therefore, the development of wearable pulse oximeter, such as ring-type pulse oximeter, can effectively solve the above issue. However, the tissue structure of finger base is complex, and there is lack of detail information for the effect of the light source and detector placement on measuring SPO2. In this study, the practicability of ring-type pulse oximeter with multi-detectors was investigated by optical human tissue simulation. The optimal design of ring-type pulse oximeter, that can provide the best efficiency of measuring SPO2, was discussed. The efficiency of ring-type pulse oximeter with single detector and multi-detectors 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. |
