Blood pressure detection device and blood pressure detection method thereof

Abstract

The invention discloses a blood pressure detection device and a blood pressure detection method thereof. The blood pressure detection device comprises an elastic band; the elastic band is provided with a measuring box; a measuring chamber is arranged inside the measuring box; a blood pressure sensor is arranged inside the measuring chamber; a flow valve capable of controlling a flow of the blood pressure sensor is arranged inside the measuring chamber; a pressure sensor arranged above the left of the blood pressure sensor is arranged inside the measuring chamber. The blood vessel is compressed with a hydraulic pressure device and a solid presser herein so that the solid presser can compress the blood vessel fast; during reduced pressure measurement of blood pressure, pressure of oil decreases stably since the hydraulic oil is nearly uncompressible and hydraulic drive stability is better than pneumatic drive stability; therefore, blood pressure measuring precision is increased. Therefore, pressure increasing in blood pressure measurement herein is fast; self-pressure drops stably during measuring; blood pressure measuring precision is improved.

Description

technical field [0001] The invention relates to the technical field of blood pressure detection, in particular to a blood pressure detection device and a blood pressure detection method. Background technique [0002] The sphygmomanometers currently on the market use non-invasive measurement methods, which can be divided into auscultation and oscillometric methods. The auscultation method uses cuff pressure and a stethoscope under the cuff to listen to the pulse sound to judge the measured person This measurement method requires strong professional knowledge and is generally used by doctors and nurses. It is not suitable for families and individuals to measure blood pressure. The oscillometric method is a relatively advanced electronic measurement method developed in the 1990s. Use the air pump to inflate and pressurize the cuff, and use the inflatable cuff to compress the arterial blood vessel, so that the arterial blood vessel is in a state of full open-semi-closed-complete...

[0002] The sphygmomanometers currently on the market use non-invasive measurement methods, which can be divided into auscultation and oscillometric methods. The auscultation method uses cuff pressure and a stethoscope under the cuff to listen to the pulse sound to judge the measured person This measurement method requires strong professional knowledge and is generally used by doctors and nurses. It is not suitable for families and individuals to measure blood pressure. The oscillometric method is a relatively advanced electronic measurement method developed in the 1990s. Use the air pump to inflate and pressurize the cuff, and use the inflatable cuff to compress the arterial blood vessel, so that the arterial blood vessel is in a state of full open-semi-closed-complete occlusion, and the pressure sensor collects the pressure in the cuff that changes in size and converts it into a digital signal Send it to the CPU, identify the corresponding pressure points in the process of arterial blood flow obstruction through the embedded software, and obtain the diastolic and systolic blood pressure of the human body based on the software algorithm accumulated by experience. Longer, and due to the certain compressibility of the gas, the pressure drop of the cuff itself during the deflation process of the inflatable cuff is not uniform enough, thereby affecting the accuracy of blood pressure measurement. A device that can solve the above-mentioned problems is explained in the present invention
