Problems solved by technology

It is difficult to measure various parameters of the autonomic nervous and cardiovascular system. Invasive methods are often used clinically, that is, injecting phenylephrine (vasoconstrictor) to the patient to cause blood pressure to increase and heart rate to decrease. However, this method of measuring by injecting drugs often not accepted by patients

Embodiment Construction

[0016] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and that the embodiments are not intended to limit the scope of the invention. Rather, these embodiments are provided to enable those skilled in the art to more thoroughly understand the present invention.

[0017] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, and There are three cases of B. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship.

[0018] The principle of the stand-up test is as follows: when a normal human body changes from a...

Abstract

The invention discloses a device and a method for measuring an autonomic nervous cardiovascular system using a stand-up experiment. The device comprises a data acquisition unit (100) and a data processing unit (200). The data acquisition unit (100) is used for synchronously acquiring acceleration signals, electrocardiogram signals and pulse wave signals of a subject in a standing experiment and sending them to the data processing unit (200). The data processing unit (200) is configured to calculate the heart rate and the average blood pressure of the measured person, and calculate the personalized parameters of the autonomic nerve cardiac regulation model, and finally calculate the sensitivity of the baroreceptor and the activity of the sympathetic parasympathetic nerve. As that baroreceptor sensitivity and the sympathetic parasympathetic activity are use as the indexes for measure the cardiac regulation state of the autonomic nerve for real-time display, the purpose of clinically evaluating the dynamic function of the cardiovascular system is achieved.

Description

technical field [0001] The present application relates to the technical field of measuring human physiological parameters, in particular to a device and method for measuring the autonomic nervous and cardiovascular system by using a stand-up test. Background technique [0002] The summary of the "China Cardiovascular Disease Report 2017" shows that the incidence of cardiovascular disease among Chinese residents shows a trend of rapid growth and individual aggregation among younger age and low-income groups. Cardiovascular disease is characterized by high morbidity, disability and mortality, and early prevention is more critical than later treatment. The diagnosis of cardiovascular disease, especially the early diagnosis, should mainly rely on the assessment of the dynamic function of the cardiovascular system. [0003] Baroreflex Sensitivity (BRS) is the most critical in the entire cardiovascular closed-loop regulation system, and has obvious physical significance and great...
