Abstract
The invention relates to a medical appliance for detecting blood pressure, in particular to an ambulatory blood pressure monitor. Due to a blood pressure aberration rate analysis module arranged on a traditional blood pressure monitor, the ambulatory blood pressure monitor can perform statistical analysis on blood pressure value to obtain the fluctuation of the blood pressure so as to provide the blood pressure aberration parameter within a time space (24h), so that the blood pressure monitor is beneficial for doctors to adopt the most optimized treatment solution and evaluate the risk of hypertension complications.
Description
Technical field
The present invention relates to detect the armarium of blood pressure, relate in particular to a kind of ambulatory blood pressure instrument.
Background technology
At present, owing between blood pressure level, circadian rhythm and the heart of ambulatory blood pressure monitoring reflection, brain, kidney target organ damage degree, dependency preferably being arranged, as the people such as external Perloff have followed up a case by regular visits to 1076 routine hypertensive patients, at average out in the time of 5 years, find that the average dynamic blood pressure is higher, the probability that lethal and non-lethality cardiovascular event occur is just larger, and this absolutely proves that the ambulatory blood pressure value is an important influence factor for the clinical consequences of hypertension.In addition, obviously and be greater than even measuring blood pressure, the average daily high person's of ambulatory blood pressure left ventricular hypertrophy ponderal index obviously is greater than the ventricular weight index that average daily ambulatory blood pressure hangs down the person for the ambulatory blood pressure that also has the scholar to find the hypertensive patient and left ventricular hypertrophy degree of correlation.The average dynamic blood pressure at night and left ventricular mass index, the more average daily ambulatory blood pressure value of Left ventricular posterior wall thickness and interventricular septal thickness has higher dependency, the more even measuring blood pressure of ambulatory blood pressure of (24 hours) can forecast the generation of left ventricular hypertrophy more accurately to illustrate one day, and the circadian rhythm of blood pressure can be used as the predictor of left ventricular hypertrophy, the generation of prediction of hypertension intercurrent disease and dead aspect be also an independently key factor, and measure the value of ambulatory blood pressure by the ambulatory blood pressure instrument.
The ambulatory blood pressure instrument be a kind ofly be used for detecting dynamically, the armarium of continuous blood pressure, by areal survey within a certain period of time, record the data relevant with blood pressure such as systolic pressure, diastolic pressure, mean arterial pressure, heart rate, carry out the analysis of pathology for the healthcare givers.
At present, the ambulatory blood pressure instrument on market is divided into cuff type and finger cot type; Wherein, the ambulatory blood pressure instrument of cuff type is comprised of transducer, miniature recording box and recovery system, give the cuff inflation/deflation by timing, to measure brachial arterial pressure, and storing data automatically, can store at most more than 200 pressure value in one day (24 hours), then in full machine recovery system analysis, print pressure value.The ambulatory blood pressure instrument of finger cot type is divided into two kinds: a kind of is that a pressure transducer, the arterial pressure referred to measure left hand are installed on fingerstall; Another kind of for measuring Pulse transit time, after being inputted to computer, data calculate systolic pressure, diastolic pressure and mean arterial pressure, and can measure pressure value more than 2000 times every day.
And in recent research, the Variation of Blood Pressure rate more and more attracts much attention, the researchs such as Parati find that Variation of Blood Pressure rate (BPV) can be used as one of index of assessment hypertension complication, Ohasama research also finds that the Variation of Blood Pressure rate can be used as one of individual index of assessment stroke risk, there are in addition report Variation of Blood Pressure rate and ARR incidence rate to be negative correlation, when the Variation of Blood Pressure rate increases, incidence of arrhythmia increases thereupon.So the Variation of Blood Pressure rate is accurate for the doctor, the fluctuation situation of objective appraisal patient blood pressure, effectively formulates therapeutic scheme, drug evaluation, the prophylaxis of hypertension complication has improved new reference frame.
But, the function that existing ambulatory blood pressure instrument (cuff type and finger cot type) does not all have Variation of Blood Pressure (BPV) to analyze, can not provide one day (24h) interior blood pressure variability parameter, thereby affect the control situation of comprehensive objective evaluation blood pressure, be unfavorable for that the doctor takes optimized therapeutic scheme to reach the risk assessment to the hypertension complication incidence rate.
