-what blood pressure monitor good
1, Omron blood pressure monitor, produced in Japan, belongs to the most cost-effective one, the family is more common. Price from more than 200 yuan to more than 1,000 yuan ranging, fast and accurate measurement, and easy to understand the operation, more suitable for the elderly at home.
2, Yuyue sphygmomanometer, Jiangsu Yuyue Medical Equipment Co., Ltd, its "Yuyue brand sphygmomanometer" and "Yuyue brand wheelchair cart" were respectively awarded by the General Administration of Quality Supervision, Inspection and Quarantine, "China famous brand! "Yuyue blood pressure monitor" and "Yuyue wheelchair trolley" were awarded "China Famous Brand" by the General Administration of Quality Supervision, Inspection and Quarantine of China respectively, which is the first enterprise in the medical equipment industry to be awarded "China Famous Brand", and is also the only medical equipment manufacturer in China with two "China Famous Brands".
3, nine Ann sphygmomanometer, made in China, the measurement is also very accurate, the price is between 159-500 yuan, in the measurement of blood pressure on the basis of the six advantages: (1) arrhythmia reminder function; (2) blood pressure zoning display; (3) individualized pressurization, the measurement of a more humane; (4) cuff measurement instructions; (5) time memory display; (6) a large screen display, the appearance of a more Aesthetically pleasing. Some models also add the function of voice announcement.
-Identify the method of electronic sphygmomanometer
Electronic sphygmomanometer using sensors to collect pulse signals, measuring high pressure, low pressure values, high sensitivity, and its work is not subject to external sound and other factors interfere; mercury sphygmomanometer is through the person to listen to the pulse beat, with the eyes to observe the scale of the mercury, coupled with mercury sphygmomanometer the minimum scale specifications are not the same, and some even 5mmHg for the smallest unit, so it is decided that the doctor reported readings are not the most accurate readings, but not that the doctor measured wrong, is determined by the characteristics of the tools used
Both are non-invasive indirect measurement of blood pressure. 1905 Soviet doctor KopomkoB proposed that under normal circumstances, the arteries under complete pressure does not emit any sound, only when the arteries are incompletely blocked only to Therefore, sound can be used to determine blood pressure in humans. The auscultation method utilizes the principle of Koch sound pressure measurement and consists of a sphygmomanometer, a cuff and a stethoscope. The measurement process is to inflate the cuff with an inflatable ball, and when the cuff pressure exceeds the arterial systolic pressure, the arterial vasculature is closed and blood flow is blocked. Then deflate the cuff at a rate of 2-3mmHg/s. When the systolic pressure is higher than the cuff pressure, part of the artery opens and the blood jet forms a vortex or turbulence, which vibrates the blood vessels and transmits to the surface of the body, i.e., the Cochrane's tone, which is heard by the stethoscope. The pressure in the cuff corresponding to the first Koch sound is systolic, and diastolic when the sound is lowered to silent
The electronic sphygmomanometer is based on the vibration method. In the process of increasing or decreasing the static pressure, the pulsatile pressure is extracted, amplified and its envelope is depicted, and then the geometry of the envelope is analyzed, and the static pressure corresponding to the highest point of the envelope is the mean pressure. From the mean pressure, diastolic and systolic pressures are estimated by the ratio method or the inflection point method.
