Health weighs the major criterion of people's living standard, is also the theme that the mankind are concerned about forever always.Along with the development of society, the rapid raising of living standard, medical skill is progress constantly, and the disease cannot cured before a lot of also can obtain good treatment; On the other hand, social development makes people's rhythm of life accelerate, work and life stress increase, add the problems such as the environmental pollution that industrial development brings, all serious challenge is proposed to the health of people, the factor of much new harm humans health is also comed one after another, and as hypertension, coronary heart disease, diabetes, hyperlipidemia, obesity and apoplexy etc., these have been listed in the topmost disease of harm humans health.
Pulse transit time (PTT), is defined as the conduction time for the pressure pulse of being initiated by the heart beating in the Arterial system of patient, and it makes systolic pressure and diastolic pressure be mutually related shown in large quantity research.For the measurement of blood pressure, current PTT typically utilizes traditional vital sign monitors to measure, and described vital sign monitors comprises the separate modular determining electrocardiogram (EGG waveform) and pulse formula oximetry (SpO2).In PTT measuring process, multiple electrode is typically attached to the chest of patient, to determine by being called as " the obvious sharp shaped material (sharpspike) of QRS complex wave " for time dependence composition in the EGG waveform of feature.The initial depolarization of QRS complex wave instruction endocardial ventricle, and make ensuing heart beating and pressure pulse start off the record.SpO2 typically utilizes the sensor being attached to bandage on patient's finger or clothes peg shape to measure, and is included in the optical system that red and infrared spectrum region works.The radiation of being launched by optical system measured by photodetector, and its finger by patient transmits.Other body part (such as, ear, forehead and nose) also can be used for replacing finger.In measuring process, the redness of microprocessor analysis measured by photodetector and infrared radiation, with the time dependence waveform that the different wave length determined be called as light plethysmograph (' PPG waveform ') is corresponding.According to these waveshapes SpO2 value.Pulse rates in tremulous pulse below (such as, in the finger) of PPG waveform time dependency characteristic instruction caused by propagation pressure pulse and the change of volumetric absorptance.
Typical PTT measures the time of the part (arrival of indicated pressure pulse) being separated maximum point on QRS complex wave (peak of instruction sequences of ventricular depolarization) and PPG waveform.PTT depends primarily on arterial compliance, the propagation distance (it is closely similar to by the arm length of patient) of pressure pulse and blood pressure.In order to consider patient-specific attribute, such as, arterial compliance, the blood pressure measurement based on PTT comes " calibration " typically via using traditional sphygomanometers cuff.Typically, in a calibration process, sphygomanometers cuff is applied on patient, and it is used for carrying out once or repeatedly blood pressure measurement, and then removes.Proceed, use calibration algorithm, change blood pressure and the blood pressure change rate of coming together to determine patient together with PTT.PTT is typically relevant to blood pressure inverse ratio, that is, PTT reduces instruction blood pressure increases.
For the problems referred to above, need a kind of ambulatory blood pressure monitoring device and method badly, environmental protection, cost be low, easy to use, detection time long, attractive in appearance portable, can real-time dynamic monitoring and the management blood pressure of hyperpietic and the equipment of heart rate in conjunction with cloud platform.
