CN1698536 discloses " a kind of adopt auto-compensation without cuff type continuous BP measurement method ".The method, by measuring the characteristic quantity relevant to the pulse wave of measured, is determined the influential first factor parameter of described characteristic quantity; Determine the second factor parameter blood pressure of measured impacted because of the physiological activity change of measured; Based on described characteristic quantity, utilize described first and second factor parameters as compensation dosage, determine the arteriotony of measured.The blood pressure measurement error that the method will cause the change of various factors compensates, but also cannot realize measuring by shooting continuously measured's blood pressure, and trimming process is loaded down with trivial details, and accuracy is not high yet.
CN104173036 discloses " a kind of pulse wave harvester, non-invasive blood pressure continuously by shooting measuring system and method ".System that employs hemodynamic detection analyser to be wirelessly connected with pulse wave harvester, the brachial pulse ripple signal that acquisition pulse wave harvester collects and radial artery pulse wave signal carry out computational analysis, carry out continuously non-invasive blood pressure by shooting and measure.This method solve the shortcoming that non-invasive blood pressure measurement device and method measuring operation in prior art are loaded down with trivial details, but the analytical tool hemodynamic in designed system detects bulky being not easy to of analyser to be carried.
CN104739413 discloses " a kind of sound of snoring detection method and system ".This sound of snoring monitoring system, continues at the gas outlet place of respirator to detect breath signal; Oscillation Amplitude value according to the described breath signal continuing to detect obtains breathing vibration threshold value; When the Oscillation Amplitude value of the described breath signal detected in the last time is greater than described breathing vibration threshold value, assert that the breathing corresponding to the breath signal that described the last time detects there occurs the sound of snoring.This method be unable to do without respirator equipment, bulky, is not suitable for family's monitoring and uses.
Wearable parameter monitoring system is merged mutually by the medicated clothing of vital signs information monitoring technology with the daily wearing of people, makes it realize the acquisition of vital signs information in its natural state, and it is a kind of monitoring technology of safe low physiological load.Chinese patent 201520257378X provides " a kind of wireless breathing, pulse monitoring device ".Adopt piezoelectric film sensor and the flexible circuit with special construction elastic base, improve sensitivity and the convenience of sensor, device can wireless transmission, can remote access, there is abnormal signal warning function, can be used for the monitoring of the monitoring of sleep Apnea Syndrome syndrome, motion monitoring and Depth of sleep etc.But little in order to realize volume, lightweight, to be easy to carry etc. and to require and sacrifice the capacity of battery, can not realize using for a long time, be unfavorable for daily monitoring.
