Embodiment 1

[0025] Blood pressure is measured as follows:

[0026] Step 1: Use gas pump equipment to inflate the cuff automatically. Each inflation increases the pressure by 15mmHg, detects and identifies the maximum value of the pulse wave, and the pressure at this time is the average pressure; continue to inflate to detect the pulse, when the pulse intensity is the pulse wave At 50% of the maximum value, the pressure at this time is the systolic pressure; the first inflation measurement is completed, and the diastolic pressure is calculated according to the measured oscillation waveform, wherein the value of the diastolic pressure is less than the average pressure, and the pulse intensity is pressure at 60% of maximum pulse intensity;

[0027] Step 2: Carry out the second inflation measurement, inflate until the air pressure value is 15mmHg higher than the systolic pressure, and then gradually deflate for pulse wave detection. Each deflation reduces the pressure by 5mmHg. During the def...

Embodiment 2

[0031] Blood pressure is measured as follows:

[0032] Step 1: Use the gas pump equipment to inflate the cuff automatically. Each inflation will increase the pressure by 10mmHg, detect and identify the maximum value of the pulse wave, and the pressure at this time is the average pressure; continue to inflate to detect the pulse, when the pulse intensity is the pulse wave At 50% of the maximum value, the pressure at this time is the systolic pressure; the first inflation measurement is completed, and the diastolic pressure is calculated according to the measured oscillation waveform, wherein the value of the diastolic pressure is less than the average pressure, and the pulse intensity is pressure at 60% of maximum pulse intensity;

[0033] Step 2: Carry out the second inflation measurement, inflate until the air pressure value is 10mmHg higher than the systolic pressure, and then gradually deflate for pulse wave detection. Each deflation reduces the pressure by 3mmHg. During th...

Embodiment 3

[0036] Blood pressure is measured as follows:

[0037] Step 1: Use gas pump equipment to inflate the cuff automatically. Each inflation increases the pressure by 40mmHg, detects and identifies the maximum value of the pulse wave, and the pressure at this time is the average pressure; continue to inflate to detect the pulse, when the pulse intensity is the pulse wave At 50% of the maximum value, the pressure at this time is the systolic pressure; the first inflation measurement is completed, and the diastolic pressure is calculated according to the measured oscillation waveform, wherein the value of the diastolic pressure is less than the average pressure, and the pulse intensity is pressure at 60% of maximum pulse intensity;

[0038] Step 2: Carry out the second inflation measurement, inflate until the air pressure value is 20mmHg higher than the systolic pressure, and then gradually deflate for pulse wave detection. Each deflation reduces the pressure by 5mmHg. During the def...

Abstract

The invention provides a method for measuring blood pressure, specifically comprising steps of automatically pumping an oversleeve with a gas pump, 10-20mmHg for pumping each time, detecting to identify maximal value of pulse wave, the pressure is mean pressure; going on pumping to measure pulse, when pulse wave intensity is 50% of the maximal value of pulse wave, the pressure is systolic pressure; calculating diastolic pressure according to the oscillogram obtained by measuring; pumping until the pressure is 10-20mmHg higher than the systolic pressure, then gradually discharging gas to measure systolic pressure, 13-5mmHg for discharging each time, during the discharging process, using an optical pulse detecting device and a sonic pulse detecting device to correct the systolic pressure, when the optical pulse detecting device has detected optical signals and the sonic pulse detecting device has detected sound signals, the pressure is the corrected systolic pressure. Advantage of the method lies in that noninvasive blood pressure measurement is more accurate, and measuring precision and consistency are improved.

Description

technical field [0001] The invention relates to a blood pressure measurement method, which can be used in automatic sphygmomanometers, monitors and other instruments related to human blood pressure measurement, and belongs to the technical field of blood pressure measurement. Background technique [0002] The current methods of non-invasive blood pressure measurement mainly include: [0003] 1. Auscultation method based on the change of the vibration tone of the vessel wall - Korotkoff sound method; [0004] 2. Ultrasonic method based on the principle of Doppler ultrasound; [0005] 3. Oscillation method (oscillometric method) based on pulse pressure oscillation. [0006] The most widely used method at present is the Korotkoff sound method, followed by the oscillation method used in recent years. The advantage of non-invasive blood pressure measurement is that it is painless and the measurement is simple and convenient. But there are also many disadvantages: [0007] 1....
