Embodiment Construction

[0033] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0034] Such as figure 1 As shown, a manually pressurized electronic sphygmomanometer includes: an inflatable cuff, a microprocessor (MCU), a measurement system, and a control system. The measurement system consists of two parts: a pressure measurement and a pulse measurement. Pressure measurement is divided into pressure sensor, pressure signal amplifier, pressure signal A / D converter. Pulse measurement is divided into pulse signal filter amplifier and pulse signal A / D converter. The control system includes button control, microprocessor (MCU), and LCD display.

[0035] In addition, a stethoscope, a manual air pump, and a vent valve are used in conjunction with the electronic sphygmomanometer.

[0036] Pressurize before measuring blood press...

Abstract

The invention provides a blood pressure measurement method. The operator listens to the Korotkoff sound through the stethoscope to measure the blood pressure of the human body: the microprocessor automatically obtains the pulse signal and records the pressure value of the inflatable cuff corresponding to the pulse signal; the operator hears the snapping sound At the first sound, immediately press the button to control the microprocessor to automatically record the pressure of the inflatable cuff as the systolic pressure; when the operator hears the disappearing sound, immediately press the button to control the microprocessor to automatically record the pressure of the inflatable cuff as the diastolic pressure ; The above-mentioned pressure values ​​are displayed on the display together as systolic blood pressure, diastolic blood pressure and pulse. The invention also relates to a sphygmomanometer implementing the method described above. The invention can not only satisfy the doctor's operating habits in blood pressure measurement, but also give full play to his professional skills, and can also achieve simple operation, convenient data recording, accurate reading of required values, simple structure, and convenient use.

Description

technical field [0001] The invention relates to a method for measuring blood pressure of a human body, in particular to a method for measuring blood pressure by auscultation. The invention also relates to a sphygmomanometer for carrying out the method. Background technique [0002] Blood circulation delivers oxygen and various nutrients to the whole body of the human body, and takes away carbon dioxide and other waste products. It is a complete and complex system consisting of the heart, blood and vascular network. Blood circulates and flows in the vascular network, relying on the action of the "blood pump" of the heart, which causes the rear pressure to be higher than the front through contraction and relaxation, that is, blood pressure, forcing blood to flow forward. [0003] Russian scholar Korotokoff (Korotokoff) found that the upper arm was bound with an inflatable cuff and pressurized, the brachial artery was compressed, and then decompressed. With the reduction of t...
