Embodiment 1

[0048] Such as figure 1 , Figure 2A , Figure 2B , Figure 2C , Figure 2D with Figure 4 In a non-invasive multi-channel pulse wave detection device shown in an embodiment, n=2, that is, two pulse waves are selected to be collected. include:

[0049] The first sensor and the second sensor adopt PT14M3 physiological pressure sensor, the first sensor is connected with the amplifying circuit, and the second sensor is connected with the amplifying circuit.

[0050] The first sensor is placed in the carotid pulse wave detection sensor fixing device, and the second sensor is placed in the radial artery pulse wave detection single-contact sensor fixing device. They are used to detect carotid artery pulse wave and radial artery pulse wave respectively.

[0051] The amplifying circuit and the amplifying circuit are mainly composed of an amplifying chip AD620, which respectively amplifies the pulse wave signals collected by the first sensor and the second sensor.

[0052] The ...

Embodiment 2

[0166] This embodiment differs from Embodiment 1 in that n=6 is selected in this embodiment, that is, six channels of pulse waves are used to analyze the pulse wave velocity and waveform. A non-invasive multi-channel pulse wave detection device in this embodiment includes:

[0167] The first sensor is placed in the carotid artery pulse wave detection sensor fixing device, the second and third sensors are placed in the radial artery pulse wave detection single-contact sensor fixing device, the fourth and fifth sensors are placed in the ankle pulse wave detection sensor fixing device, the second The six sensors are fixed at the detection position by hand after the other sensors are fixed. They are respectively used to detect the carotid artery pulse wave, the radial artery pulse wave on both sides, the ankle artery pulse wave on both sides, and the femoral artery pulse wave.

[0168]The six-channel amplifier circuit is mainly composed of the amplifier chip AD620, which amplifie...

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...
