Embodiment Construction
[0037] Based on the drawings, a preferred embodiment of the present invention is introduced. In the drawings, the same reference signs indicate the same or functionally similar components. In the drawings, the leftmost number in the reference number corresponds to the drawing in which the reference number is first used.
[0038] figure 1 It is a schematic diagram of the diagnosis system 100 according to the present invention. The diagnostic system 100 includes a diagnostic device 102, a diagnostic computer 104, a cuff 106, a Doppler sensor 108 and blood oxygen saturation (StO 2 ) Sensor 110.
[0039] In this application, the volume pulse wave is the blood pressure oscillation between the arterial systolic and diastolic blood pressure. The diagnosis system 100 detects volume pulse waves, and performs diagnosis based on the detected pulse waves to assess changes in the arterial volume of the limb segment. In some embodiments, the volume pulse wave includes a composite pulse wave ...
