Abstract

A Korotkoff sound electronic sphygmomanometer is characterized in that the Korotkoff sound electronic sphygmomanometer comprises a microprocessor, an amplifying and filtering system, a cuff inflation and deflation control system, a pressure regulating module, a charging module, a liquid crystal display module, a storage module, a clock module and a USB module, wherein the amplifying and filtering system, the cuff inflation and deflation control system, the pressure regulating module, the charging module, the liquid crystal display module, the storage module, the clock module and the USB module are all connected with the microprocessor, a pressure sensor and a vibration sensor send signals to the microprocessor through the amplifying and filtering system, a lithium battery is connected with the pressure regulating module and the charging module, the USB module is connected with blood pressure measuring software, and the microprocessor is an MSP430FC437 single-chip microcomputer. Aiming at the defects of a riva-rocci sphygmomanometer and an oscillography electronic sphygmomanometer, the Korotkoff sound electronic sphygmomanometer integrates the advantages of the riva-rocci sphygmomanometer and the oscillography electronic sphygmomanometer to achieve portability, low power consumption and intelligentization of a blood pressure measuring instrument, and the blood pressure can be measured more accurately.

Description

technical field [0001] The invention relates to a Korotkoff sound electronic sphygmomanometer, which belongs to the field of medical instruments. Background technique [0002] Blood pressure is the pressure, or pressure, exerted by the blood in a blood vessel as it flows through the wall of the blood vessel. With the continuous improvement of living standards and the increase of the proportion of urban aging, the familyization of medical testing equipment has gradually become a trend. For example, when you wake up in the morning, you feel listless, dizzy, weak, and unable to concentrate, but you feel much more comfortable lying in bed, and no abnormalities are found in the hospital. Most of these conditions are caused by blood pressure problems, and people should pay great attention to them. Hypertension is one of the most certain and important risk factors for cardiovascular and cerebrovascular diseases. Increased systolic blood pressure mainly affects left ventricular di...
