Patent ID: 8600468

Claim:
A pulse oximeter attached to a living body for acquiring an arterial oxygen saturation as biometric information thereof, said pulse oximeter comprising: a sensing portion for detecting a biometric signal representative of the arterial oxygen saturation; a processing portion for deriving oxygen saturation information from the biometric signal detected by said sensing portion; an analyzing portion for analyzing one of the biometric signal and the oxygen saturation information data; a positioning portion for acquiring position information indicating the current location of said sensing portion by use of radio waves; a storage portion for storing one of the biometric signal detected by said sensing portion and the oxygen saturation information derived by said processing portion; a controller configured to instruct said position portion to perform an operation of acquiring the position information at a specified time interval during measurement of the oxygen saturation, and wherein the controller is further configured to cause the sensing portion to detect the biometric signal and the storage portion to store the biometric signal or the oxygen saturation information in association with the position information when the current location acquired by the positioning portion matches a predefined site.
