Problems solved by technology

Bio-impedance measurement method is difficult to use
Given that bioimpedance technology requires the application of electricity to the patient's skin, it is difficult for the patient to tolerate the resulting skin tingling
Furthermore, the measured signal varies greatly

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 ...

Abstract

A medical diagnostic device performs diagnostics for assessing the ability of the arteries to respond to an increase in blood flow. The medical diagnostic device determines relative changes in arterial volume of the limb segment during a time period after a stimulus relative to the arterial volume of the limb segment during a baseline period using the amplitudes or other portions of the component pulse waves (such as early systolic components) of volume pulse waves during the baseline period and after the stimulus.

Description

[0001] inventor [0002] Alexander Palfinov [0003] Maria Palfinova [0004] Niroly Konstantinov [0005] Cross references to related applications [0006] According to 35USC §119(e), this application claims priority to the US provisional application number 61 / 177,341 filed on May 12, 2009 with the title of “System and Method for Measuring Changes in Limb Arterial Volume”, and The full text is cited in this application. Technical field [0007] The present invention mainly relates to the measurement and evaluation of changes in the arterial volume of limb segments. Background technique [0008] Cardiovascular disease is a major factor in morbidity and death. It has been proven that by measuring the ability of arteries to expand in response to increased blood flow, early cardiovascular disease can be diagnosed. The degree of arterial dilation in response to increased blood flow is correlated with the severity of cardiovascular disease. [0009] Endothelial cells form the inner wall of ...
