Embodiment 1

[0022] figure 1 It shows a flow chart of a method for measuring pulse pressure difference provided by the first embodiment of the present invention, which is described in detail as follows:

[0023] Step S11, acquiring the photocurrent signal transmitted by the artery, and extracting the volumetric wave signal according to the photocurrent signal.

[0024] The volumetric wave signal here refers to the obtained two-way transmitted (or reflected) photocurrent signals of specific parts of the human body, and the quality of the photocurrent signals is relatively stable without large fluctuations. The photocurrent signals are converted by current-voltage , hardware amplification and analog-to-digital conversion, etc., to obtain two digital signals containing volumetric wave information.

[0025] Specifically, the photocurrent information transmitted by a specific part of the artery (such as terminal finger artery, carotid artery and forehead artery, etc.) The two photocurrent sig...

Abstract

The invention is applicable to the field of medical monitoring, and provides a method and device for the measurement of pulse pressure difference. The method includes the following steps that a photocurrent signal of artery transmission is obtained, and according to the photocurrent signal, a volume wave signal is extracted; according to the volume wave signal, the volume variation quantity is determined; according to the corresponding relation between the volume variation quantity and the blood pressure variation quantity, the pulse pressure difference is determined. By means of the method, the determination speed of the pulse pressure difference can be improved.

Description

technical field [0001] The embodiments of the present invention belong to the field of medical monitoring, and in particular relate to a method and device for measuring pulse pressure difference. Background technique [0002] Pulse pressure difference is the difference between systolic blood pressure and diastolic blood pressure, and its value has very important clinical significance. [0003] Framingham research shows that when the pulse pressure is too high, the incidence of cardiovascular risk events (such as coronary heart disease) is significantly increased, which is common in arterial valve insufficiency, aortic sclerosis, hyperthyroidism, severe anemia, hypertensive heart disease and other diseases; and A low pulse pressure indicates that the elasticity and compliance of peripheral blood vessels have decreased. [0004] In addition to monitoring chronic diseases, the monitoring of pulse pressure difference can also serve as a reminder for the sudden situation of clin...
