Embodiment Construction

[0026] The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention. Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as the way to distinguish components, but use the difference in function of the components as the criterion for distinguishing. The subsequent description of the specification is a preferred implementation mode for implementing the present invention, but the description is for the purpose of illustrating the general principles of the present invention, and is not intended to limit the scope of the present invention. The scope of protection of the present invention should be defined by the appended claims.

Abstract

The invention discloses a non-invasive blood pressure simulator based on a Korotkoff sound production mechanism. The non-invasive blood pressure simulator comprises a haemodynamic simulation device and an upper arm model, wherein the haemodynamic simulation device is used for producing a simulation blood flow adjustable in amplitude and frequency and producing a pulsating flow required by a brachial artery input of the upper arm model, and the upper arm model is wholly cylindrical and used for simulating the upper arm consisting of the human body brachial artery and muscles, is sleeved by a blood pressure cuff and produces vibration under the cuff pressure to form a Korotkoff sound signal. The non-invasive blood pressure simulator belongs to a extracorporeal circulation simulation system, achieves simulation of blood pressure and blood flow distribution in the aorta and brachial artery, achieves simulation of human body blood pressure non-invasive measuring process on the basis that the Korotkoff sound and oscillatory wave production mechanism is analyzed, and accordingly achieves metrological verification of an electronic sphygmomanometer.

Description

technical field [0001] The invention relates to the field of medical machinery, in particular to a non-invasive blood pressure simulator based on the generation mechanism of Korotkoff sounds. Background technique [0002] The blood pressure value measured by the sphygmomanometer usually refers to the arterial blood pressure, that is, the lateral pressure of the blood in the arterial vessel on the vessel wall per unit area, including systolic pressure and diastolic pressure. Sphygmomanometers can be divided into invasive and non-invasive according to the measurement method. At present, non-invasive sphygmomanometers are widely used, and electronic sphygmomanometers are typical representatives of non-invasive sphygmomanometers. [0003] Electronic sphygmomanometers usually use the oscillometric method to measure blood pressure, that is, measure systolic, diastolic and mean pressures through automatic analysis of high-frequency pressure oscillation wave signals in the cuff.
