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] According to the drawings, a preferred embodiment of the present invention is introduced. In the drawings, like reference numbers indicate identical or functionally similar components. In the figures, the leftmost digits in a reference number correspond to the figure in which the reference number is first used.

[0038] figure 1 is a schematic diagram of a diagnostic 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 a blood oxygen saturation (StO 2 ) sensor 110.

[0039]In this application, a volume pulse wave is a blood pressure oscillation between arterial systolic and diastolic pressures. The diagnostic system 100 detects a volumetric pulse wave, and performs a diagnosis based on the detected pulse wave to assess volume changes in limb segment arteries. In some embodiments, the volumetric pulse wave comprises a composite pulse wave formed by ...

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 Parfinov [0003] Maria Palfinova [0004] Niroy Konstantinov [0005] Cross References to Related Applications [0006] Pursuant to 35USC §119(e), this application claims priority to U.S. Provisional Application No. 61 / 177,341, filed May 12, 2009, entitled "System and Method for Measuring Variation in Arterial Volume in Extremity Segments," and will It is incorporated by reference in its entirety in this application. technical field [0007] The present invention mainly relates to the evaluation of arterial volume changes in limb segments. Background technique [0008] Cardiovascular disease is a major factor in morbidity and mortality. Early cardiovascular disease has been shown to be diagnosed by measuring the ability of arteries to dilate in response to increased blood flow. The extent to which arteries dilate in response to increased blood flow correlates with the severity of cardiovascular disease. [0009] Endothelial cells m...
