Abstract

The invention discloses a non-invasive multipath pulse wave detection device, which comprises at least two sensors, each of the sensors is provided with a fixing device thereon and connected to a signal processing unit, and the signals detected by the sensors are processed and stored by the signal processing unit. The invention synchronously collects pulse waves and wave velocities in a multipathmanner and uses a wave form processing technique for the pulse wave collecting points of the different sites of a human body, is capable of analyzing the wave velocities and the wave forms aiming at the different sites of the human body, and provides more specific information reflecting cardiovascular system states for clinic real-time monitor.

Description

technical field

[0001] The invention relates to a non-invasive multi-channel pulse wave detection device, method and analysis system. Background technique

[0002] The human heart, arteries, capillaries and veins make up the cardiovascular system. In the cardiovascular system, with the periodic ejection of blood from the heart, not only the periodic pulsating blood velocity flow propagates in the arteries, but also the high and low pulsations of the blood pressure and the vibration of the vessel wall expanding and contracting in the arteries. Propagate forward in the vascular system. The propagation process of blood velocity, flow rate and pressure pulsation or blood vessel wall vibration in the arterial vascular system is called the propagation of pulse wave in the artery. From a mechanical point of view, the pulse wave is composed of blood flow and blood vessel wall vibration. Once the heart, blood or blood vessel wall tissue structure changes, it will inevitably lead to...
