| titleOfInvention | Pulse oximeter |
| abstract | In a pulse oximeter, SpO 2 value is accurately measured even for a low-perfusion subject with small pulsation without causing an adverse effect due to an increase in emission energy. A pulse oximeter that noninvasively measures an SpO 2 value by utilizing a difference in absorption characteristics (a ratio of pulse wave amplitude components) of two wavelengths of red light R and infrared light IR in a living body. , The AC components R AC , IR AC and the DC components R DC , IR DC of the transmitted light are sequentially and periodically measured in order to cancel the influence of the difference in the light emission levels of the light emitting elements that respectively generate the two wavelengths of light. in, the conventional detection period T1 shown in (a), as shown in (b), by the time alpha, the DC component R DC, the detection period of the IR DC R-DC, while shortening the IR-DC, alternating current component R AC, IR AC detection period R-AC, extending the IR-AC.
