Entirely contactless, do not need not needing more to paste disposable electrode on the skin in human body in human body using elastic webbing bondage
Piece.When acquiring During Night Time dormant data, tester will not feel good for contactless design, and sleeps to tester
Dormancy does not have interference, and the data of acquisition are closer to truthful data.Since the utility model embodiment sensing zone 100 is and human body
Entirely contactless and do not interfere user sleep, so may be due to rolling or leaning to one side during tester's nighttime sleep
Situation causes electrocardioelectrode that can not collect electrocardiosignal well, so integrating the BCG signal of acquisition in sensing zone of the present invention
Sensor, it is ensured that even if cannot detect in cardiac electrical situation, can also collect tester sleep the whole night in BCG signal,
It is dynamic to the heart rate of tester, breathing and body to carry out signal acquisition.The treatment process of BCG signal is filter out power frequency and noise dry
It disturbs, extracts the features such as RR interphase, by carrying out just mesh analysis to tester's sleep apnea to BCG signal processing.The present invention
Sensing zone as a result, can be locally stored, can also be transferred to after ECG and BCG signal processing analysis by wireless blue tooth
It is directly viewable on mobile phone or on computer, facilitates and be supplied to clinician as auxiliary information report.
In the utility model embodiment, sensing zone 100 includes: sensing band body 10；Multiple electrocardioelectrodes 20, electrocardio
Electrode 20 is arranged at intervals in sensing band body 10, and electrocardioelectrode 20 is for acquiring electric signal；Master controller 30, with electrocardio electricity
Pole 20 connects, and master controller 30 is used to form electrocardiogram (ECG) data according to electric signal.It is possible thereby to very easily when user sleeps
Just cardioelectric monitor is carried out to user, in addition, sensing zone 100 further includes piezoelectric membrane 40, is not thus needing artificial excessive do
Influence in advance and not sleep comfort level in the case where, realize in sleep cordless simultaneously acquire human body ECG signal and
BCG signal, and processing analysis is carried out to the signal of acquisition, the early warning of cardiac-related diseases is provided, and can provide for clinician
Auxiliary information report.
The foregoing is merely the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
