Abstract

A probe for use in photoplethysmographic (PPG) measurement includes a light source unit including a light source that contacts a predetermined site of an object and emits light onto the predetermined site, a photodetector unit positioned facing the light source unit to receive the light emitted from the light source unit and transmitted through the object, a body having a space for receiving the object and in which the light source unit and the photodetector unit are positioned in a same optical axis, and a pressure application unit coupled to the body for applying a pressure to the object via the light source unit. A biological signal measuring system includes the above probe, a controller for controlling operations of the probe and for recording and analyzing signals output from the probe, a detected light intensity display unit for displaying an intensity of detected light, and a biological signal display unit.

Description

technical field [0001] The invention relates to a detector for measuring biological signals and a biological signal measuring system including the detector. Background technique [0002] Just as the metabolism of the human body varies from person to person, so does the pulsation (ie, pulse) and blood pressure vary from individual to individual. In addition, for multiple measurement locations or even the same measurement location on the same subject, the measured blood composition, blood volume, and pulsation intensity are also different when measured at different measurement times and physical conditions of the subject. Therefore, there is a need for a reliable biosignal measurement device capable of providing accurate biometric information of a subject. Such a measuring device may be a detector providing information such as a photoplethysmogram. [0003] When measuring at the biological signal detection point, the patient receiving the biological signal measurement should...
