Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0023] see figure 1 , the preferred embodiment of the present invention provides a kind of early screening method of peripheral arteriosclerosis, it comprises the following steps:
[0024] S1: Acquire pulse wave signals at different positions of the patient's body; in the present invention, preferably, the pulse wave signals are collected at the extremities of the human body through infrared photoelectric sensing technology. Specifically, a plurality of infrared photoelectric data sensors are respectively fixed on the surface skin of the limbs of the human body. The infrared photoelectric data sen...

The invention discloses an early-screening method and system for peripheral atherosclerosis.The method comprises the following steps: 1, obtaining pulse wave signals of different body positions of a patient; 2, conducting data pre-processing on the pulse wave signals; 3, conducting real-time frequency domain processing on the pulse wave signals obtained after data pre-processing, so that a continuous three-dimensional waterfall spectrogram and / or a three-dimensional contour line grey-scale map are / is obtained, and through the continuous three-dimensional waterfall spectrogram and / or the three-dimensional contour line grey-scale map, judging whether the patient suffers from arteriosclerosis or not.Optimally, a cross-correlation processing method is adopted for processing the pulse wave signals obtained after data pre-processing, and the thrombus position in artery of the limb of the patient is obtained.The early-screening method and system for peripheral atherosclerosis can be used by a clinician to assess lesion of artery of the human body and particularly used for providing reliable basis when the clinician assesses whether the human body has arteriosclerosis early stage lesion or not and whether thrombus exists in the artery or not.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an early screening method and system for peripheral arteriosclerosis. Background technique [0002] Arteriosclerosis is a primary disease that seriously affects human health. For it, early accurate, non-invasive screening and prevention are effective, simple, low-risk, and low-cost measures to improve the quality of human life. At present, it is often used to obtain the index of arteriosclerosis by processing the pulse wave signal. However, in the field of pulse wave signal processing at present, both the existing marketed products and related theories are based on time-domain processing technology. Although time-domain processing can effectively solve some cases in the early screening of peripheral arteriosclerosis in clinical application, its clinical application is still limited and accidental. For example, the thrombus cannot be located accurately, the development t...
