Description
Technical Field
The invention relates to the field of intelligent sphygmomanometers, in particular to an intelligent sphygmomanometer for removing abnormal data based on external environment monitoring.
Background
A sphygmomanometer is an instrument for measuring blood pressure, and is also called as a blood pressure instrument. The sphygmomanometer mainly comprises an auscultation sphygmomanometer and an oscillometric sphygmomanometer. The oscillometric method is also called as oscillation method, and its principle is to obtain the oscillation wave produced in the air-releasing process and convert it by means of a certain algorithm to obtain the blood pressure value. Most electronic blood pressure meters are designed by adopting the oscillometric principle. The electronic sphygmomanometer can be subdivided into an upper arm type, a wrist type, a finger type, a manual type, an automatic type and the like according to the measured position. Its advantages are simple operation, visual reading, automatic measurement only by turning on switch, and suitability for household use.
Blood pressure is affected by heart rate, and if heart rate is accelerated, and stroke volume and peripheral resistance are not changed, blood flowing to the periphery in the diastole is reduced due to shortened diastole, so that blood volume remaining in aorta at the end of diastole is increased, and diastolic blood pressure is increased. Since the blood flow rate is increased by the increase of arterial blood pressure, more blood can flow to the periphery in systole, the increase of systolic pressure is not as remarkable as the increase of diastolic pressure, and the pulse pressure is reduced compared with that before the increase of heart rate. Conversely, as the heart rate slows, the amplitude of the diastolic pressure drop decreases is greater than the amplitude of the systolic pressure drop, and thus the pulse pressure increases.
Thus, disturbances in the environment may cause the heart rate of the user to change and thereby affect the correct measurement of blood pressure.
