Abstract

The invention relates to a device for evaluating a cardiovascular autonomic nerve function. The device comprises a physiological signal collecting unit, a calculating unit and an evaluating unit, wherein the physiological signal collecting unit is used for collecting physiological signals of a detected person, and the physiological signals comprise pulse wave signals; the calculating unit is used for calculating the pulse wave conduction time of the detected person according to the physiological signals and calculating the coefficient of variation of the pulse wave conduction time within a preset time period; the evaluating unit is used for determining the cardiovascular autonomic nerve function evaluating result of the detected person according to the coefficient of variation, wherein when the coefficient of variation is within a standard range, the cardiovascular autonomic nerve function evaluating result is normal, and when the coefficient of variation is out of the standard range, the cardiovascular autonomic nerve function evaluating result is abnormal. The device is adopted for evaluating the cardiovascular autonomic nerve function, the process is simple and rapid, the result is accurate, and the high reference value is achieved.

Description

technical field [0001] The invention mainly relates to the field of medical instruments, in particular to a device for evaluating cardiovascular autonomic nerve function. Background technique [0002] The force of the heart's ejection travels down the arteries in the form of pressure waves, the speed of which is affected by blood pressure and arterial stiffness (the level of aging of the blood vessels). Pulse transit time (PTT) or pulse wave transit time (Pulse wave transit time) can be obtained by recording the pulse waveform of two arterial pulse points on the body surface and calculating the time difference between the pulse wave reaching the two pulse points. Measure and estimate the pulse wave conduction distance difference between two pulse points, record the PTT for a period of time, and obtain the pulse wave velocity (Pulse Wave Velocity, PWV). Pulse wave velocity can be used to evaluate the degree of arteriosclerosis, especially the carotid-femoral artery pulse wav...
