Probe for use in measuring a biological signal and biological signal measuring system incorporating the probe
First Claim
1. A probe for use in photoplethysmographic (PPG) measurement, comprising:
- a light source unit including a light source, the light source unit adapted to contact a predetermined site of an object and to emit 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 along a same vertical axis with respect to a surface of the body supporting the object;
a pressure application unit coupled to the body for applying a pressure to the object via the light source unit, the pressure application unit being aligned in the same vertical axis above the light source unit; and
a pressure application break button electrically connected to the probe for allowing the subject or an operator to cease the application of pressure by the pressure application unit.

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.

14. A biological signal measuring system, comprising:
-
a probe in which light is emitted onto a predetermined site of an object and the light transmitted through the object is detected; a controller for controlling the operation of the probe and for recording and analyzing signals output from the probe; a detected light intensity display unit for displaying an intensity of light detected by the probe; and a biological signal display unit connected to the detected light intensity display unit for displaying a biological signal measured from an object, wherein the probe includes; a light source unit including a light source, the light source unit adapted to contact a predetermined site of the object and to emit light onto the predetermined site; a photodetector unit positioned facing the light source unit for receiving 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 along a same vertical axis with respect to a surface of the body supporting the object; a pressure application unit coupled to the body for applying a pressure to the object via the light source unit, the pressure unit including a nut attached to an upper surface of the light source unit to be movable in a vertical direction and a bolt coupled to the nut; and an elastic member between the nut and the light source unit, wherein the pressure application unit is aligned in the same vertical axis above the light source unit; and a pressure application break button electrically connected to the probe for allowing the subject or an operator to cease the application of pressure by the pressure application unit. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
