Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with its embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0041] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

[0042] Unless otherwise defined, all technical and scientific t...

Abstract

The invention provides a multichannel pulse acquisition system. The multichannel pulse acquisition system comprises a signal acquisition unit, a signal processing unit and a signal integration unit, the signal acquisition unit is used for acquiring multiple paths of pulse wave signals, and the signal processing unit is used for denoising the multiple paths of pulse wave signals and screening the denoised multiple paths of pulse wave signals to obtain a single pulse wave signal scatter diagram; and the signal integration unit is used for performing curve fitting on the single pulse wave signal scatter diagram to obtain a pulse wave signal curve. Measurement errors caused by pulse wave signal collection through a single collection channel are avoided, and more accurate and effective pulse wave signals can be measured. Correspondingly, the invention further provides a multi-channel pulse acquisition method.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a multi-channel pulse acquisition system and method. Background technique [0002] Pulse information contains a large amount of physiological and pathological information of the human body, and is an important parameter for clinical evaluation of human health status. In the human body pulse wave signal acquisition device, the photoelectric pulse sensor is widely used. The human body pulse wave signal acquisition device generally collects the human body pulse wave signal by photoplethysmography technology. However, existing human pulse wave signal acquisition devices generally use a single acquisition channel, which is susceptible to various external factors (such as the degree of contact between the sensor and human skin, external electromagnetic interference, and human body shaking) during the process of collecting human pulse wave signals. etc.), the collected pulse w...
