Blood pressure gauge, and Korotkoff sound recognition method and device

Abstract

The embodiment of the invention provides a blood pressure gauge, and a Korotkoff sound recognition method and device, and relates to the technical field of a medical appliance. On the basis of blood pressure measuring principle of a Korotkoff sound method, the Korotkoff sound of a measuring position can be obtained; the occurring moment and the disappearing moment of the Korotkoff sound are judged; the corresponding blood pressure value is determined; the influence of subjective judgment of an operator on the measuring value is avoided; and the measuring result accuracy is improved. The blood pressure gauge comprises a cuff, a pressure sensor, a sound sensor, a pressure regulator and a processor, wherein the cuff can be worn on the measuring position of the body; the pressure regulator regulates the pressure exerted to the measuring position by the cuff; the pressure sensor collects the pressure applied to the measuring position by the cuff; the sound sensor collects blood flow sound of the measuring position; and the processor is connected with the pressure sensor and the sound sensor, and obtains the pressure values corresponding to the occurring moment and the disappearing moment of the Korotkoff sound according to the collecting results of the pressure sensor and the sound sensor in the pressure change period for determining the blood pressure value.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a blood pressure measuring instrument, a method and a device for recognizing Korotkoff sounds. Background technique [0002] In recent years, people have deepened their understanding of the role of multiple risk factors for cardiovascular disease and the protection of heart, brain, kidney and other organs, making people pay more and more attention to the prevention, diagnosis and treatment of hypertension. For hypertensive patients, it is necessary to pay close attention to the monitoring and management of blood pressure at ordinary times, and to control blood pressure by means of drug treatment according to the fluctuation of their own blood pressure. [0003] Currently commonly used non-invasive blood pressure measurement methods are mainly divided into Korotkoff sound method (mercury auscultation method) and oscillometric method. The oscillometric method is based on t...

AI Technical Summary

Problems solved by technology

The Korotkoff sound method is currently the medically recognized gold standard for blood pressure measurement, but the mercury stethoscope that uses the Korotkoff sound method to measure blood pressure requires the operator to observe the change of the mercury manometer while listening to the sound through the stethoscope, and read while distinguishing the Korotkoff sound. Taking the mercury pressure value, the subjective judgment of the operator has a great influence on the measurement results, and the results obtained by different operators are different, resulting in the inability to obtain accurate measurement values
