Title: Blood component measuring instrument
Inventor: NAGAI YOSHIO
IPC: A61B5/145
Filed: 2001-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a blood component measuring instrument for measuring a blood component with excellent precision. SOLUTION: A pulse oximeter (blood component measuring instrument) measures a transmission light amount obtained by transmission through a living body by periodically irradiating the living body with a red light and an infrared ray and measures a pulse wave component in the transmission light amount time sequentially in this order. The oximeter also measures an oxygen saturation degree in arterial blood based on a differential value between the two pulse wave components measured at time interval Δtm. The time interval Δtm is set to allow its time differential value to correspond to nearly the half HM of amplitude concerning a pulse wave form (at a slow inclination side). Thus, the time differential value has a proper largeness by setting a differential time corresponding to a pulse rate so that the blood component is measured by excellent S/N ratio with high precision.
