With the continuous improvement of material living standards, people have begun to pay more and more attention to their physical health. Whether blood pressure is normal is an important indicator of physical health, and the average incidence of chronic hypotension is perthreeFamiliesonePeople aroundUp to10%。 Therefore, it is of great significance to develop an intelligent digital sphygmomanometer that is not only suitable for family health care personnel, but also suitable for all kinds of people.
In recent years,Due to the rapid and healthy development of China's economy and the continuous changes in people's daily life and learning methods,Brain Huazhong,Death caused by cardiovascular diseases such as heart accidents has accounted for a large number of deaths in global citythirty％,among6aPingzhong case andforty-nine%The case information of patients with myocardial infarction is all caused by hypertension,Sectiontwenty-oneInternational Society for Hypertension Management（1SN2006）WillBuzhong pointed out that,ApproximatelynineBillionseventy-two thousand and two hundredten thousand,Equivalent to adult26.4,among,Developed hypertensive patients havethreeBillionthree thousand and three hundredten thousand,Developing ChinasixBillionthree thousand and nine hundredten thousand,Therefore, the management of hypertensive patients is a serious problem,The Current Situation of Hypertension in ChinaEqually pessimistic is that according totwo thousand and twoNational Health and Nutrition Survey Data, Chinese Adult HypertensionThe prevalence rate is18.8%Aboutone point sixOne billion hypertensive patients. The harm of high blood pressure to the human body is systemic and a deadly demon, directly threatening people's lives. So, we should not treat hypertension as an invisible killer.
Treatment for hypertension,The first step is to accurately measure the patient's blood pressure. Instruments for measuring and controlling blood pressureIt's called a sphygmomanometer. Sphygmomanometer can be divided into direct and indirect. The working principle of the two sphygmomanometer is different. The direct type uses a pressure sensor to directly measure the pressure change;The basic principle of the same connection type is to control the pressure applied to the tested part from the outside, and the results of internal control can be compared to“four hundred and ninety-seven”Related Analyze and judge the emergence and disappearance of information technology. The former can be continuously tested for both arteries and veins,The latter can only be used as a measure of arterial systolic and diastolic blood pressure.
The traditional type of sphygmomanometer is an analog sphygmomanometer. This kind of sphygmomanometer is complex to operate, has insufficient measurement accuracy and is greatly affected by the environment. And the accuracy of calibration often needs to be checked with an accurate mercury sphygmomanometer or sphygmomanometer. The method is to yThe U-tube is removed from the stethoscope and connected to the accurate sphygmomanometer(Sphygmomanometer)Calibrate the spring sphygmomanometer, the third arm band and the gas valve, observe the sphygmomanometer and the accurate sphygmomanometer(Sphygmomanometer)The readings are the same, but if they are different, it indicates that the calibrated blood pressure gauge is not accurate. If the readings are the same, only zero deviation will not affect actual use. If blood pressure is found, if the pointer of the sphygmomanometer cannot return to zero, do not adjust the screw without authorization to avoid damaging the movement in the sphygmomanometer. At this time, send the sphygmomanometer.
Repair at the manufacturer or designated service department of the production enterprise. therefore,The use and maintenance of such sphygmomanometer is relatively troublesome. In order to make sphygmomanometer users more convenient to use and maintain sphygmomanometer,It also allows more different people to learn to take some simple blood pressure measurements by using the sphygmomanometer,So we designed and developed a device that is more convenient to operate,Accurate measurement data,There is no need to develop an intelligent blood pressure measurement device to help people fight against hypertension.
At present, most of the sphygmomanometer used in the market are mercury sphygmomanometer, and there are also some ambulatory blood pressure recorders. The mercury sphygmomanometer must be measured by a doctor wearing a stethoscope each time. The measurement process is complex, and each doctor can only measure one person at a time, which can measure different doctors.
There may be differences in the analysis of the results. For the development of the same individual,There are many studies on factors that affect patient blood pressure,Because the time we take each measurement cannot be very long,The measured results cannot truly reflect the true blood pressure value of the tested object in certain practical situations. Introducing Pulse Wave Recording into an Ambulatory Blood Pressure Information Technology,providetwenty-fourResults of each blood pressure measurement data within hours,andAnd it can reproduce the waveform during each measurement development process. Interference and artifacts cannot be avoided in dynamic blood pressure control examinations. Most companies in the current market have ambulatory blood pressure recorders,Record only the results of each measurement pass,The doctor needs to face a group of numbers that are difficult to distinguish between true and false. The main research method of this project aims to improve the design of fully informative digital blood pressureMake each measurement transparent, combine real-time analysis with retrospective analysis, enable doctors to compare the original waveform to determine the authenticity of the data, effectively identify interference and error caused by incorrect checks, restore true blood pressure, and ensure the effectiveness and reliability of blood pressure reports.
