Description

590761 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to non-invasive non-pump type micro-sac balloon blood pressure pulsometer and its measurement method, especially a kind of systolic and diastolic blood pressure applied to human blood pressure. Balloon blood pressure pulsometer for pressure and pulse measurement. [Prior art] Blood pressure ': The pressure when blood flows through the wall of a blood vessel. The blood from the heart 'needs a thrust' to go around the body for a week. The heart pushes the blood forward by constantly shrinking and relaxing, and blood pressure has two expressions: (1) systolic blood pressure: systolic blood pressure is also called Cardiac systolic blood pressure is the blood pressure measured when the heart contracts to hit blood to the blood vessels. (2) Diastolic blood pressure: Diastolic blood pressure is also called diastolic blood pressure, which is the pressure obtained by the heart. ^ Measured by Xi Xibu. When the heart is diastolic, the pulsation is greatly reduced. Therefore, the blood pressure is set to the value of the internal voltage difference. Pulse When the viscera contracts, the blood arteries pulsate by elasticity. The traditional non-invasive blood pressure pulsometer is widely used by consumers to convert the gas into voltage to adjust the deformation of the airbag material, and the blood pressure is shown as a traditional non-invasive electronic A pressure pulse pulsometer. The undulating fluid flows into the arteries and the arteries expand elastically, and the heart returns to its original state. This artery makes periodic electronic blood pressure pulsometers with the heartbeat. It uses a digital display to show the volume, and does not need to be used with a stethoscope. Electronic blood pressure pulsometers are preferred. The principle is a signal. The pressure of the gas in the pumped inflation, slow venting device is sensed because of the pressure, and the value is reflected after passing through the Wheatstone bridge. ^
