Description
Technical field
The present invention relates to a kind of wearable electrocardio monitoring systems.
Background technology
Angiocardiopathy is to threaten maximum disease to human life in modern industrial society.And cardiovascular disease incidence
It is that there is prodigious emergentness, loses valuable early diagnosis therapeutic time, lead to serious consequence, therefore the best way
It is to prevent trouble before it happens.Daily cardiac monitoring is the important means for ensureing patients ' lives safety, is found in advance by daily monitoring
Abnormal sign can be that treatment gains time in time.
The AgCl electrodes that traditional cardiac monitoring uses, which are used for a long time, easily causes the uncomfortable reaction such as skin allergy, is not suitable in day
Often used in life.In this year, numerous scholars study the counting of wearable electrocardiogram acquisition with research institution, so as to energy
Enough electrocardiogram (ECG) datas for collecting wearer in real time in the state of daily life.Textile electrode is different from traditional conductor electrode,
It measure electrocardiosignal directly and skin contact, need not use electrolytic gel or adhesive, be very suitable for for a long time
Cardioelectric monitor.
Due to the use of not no adhesive, the impedance of textile electrode and skin contact location can increase significantly, be easy by
The interference of noise affects the quality for obtaining electrocardiosignal, while the opposite fortune of the electrode that is brought of human motion and skin
The dynamic change that will also result in contact impedance, to influence the stability of signal.
Invention content
Present invention aim to address the above problems, provide a kind of wearable electrocardio monitoring system.
The purpose of the present invention is accomplished by the following way:
Wearable electrocardio monitoring system, by bandage type fabric electrocardioelectrode, EGC analog front end modulate circuit and microcontroller system
System composition, which is characterized in that EGC analog front end modulate circuit includes buffer amplifier, AC ac-coupled circuits, right leg
The bis- T trappers of driving circuit, magnifier, high-pass filter, low-pass filter, 50Hz and post-amplifier;Bandage type
Fabric electrocardioelectrode extracts human ecg signal, and a buffer amplifier is connect behind electrode and converts high impedance signal to low-resistance
Antinoise signal;The electrocardiosignal extracted is efficiently couple in subsequent signal processing circuit by AC ac-coupled circuits;Instrument
Amplifying circuit is amplified two paths of differential signals, by high-pass filter, low-pass filter and the bis- T trappers processing of 50H
Afterwards, two level amplification is carried out by post-amplifier to the signal of processing, electrocardiosignal amplitude is amplified to volt rank, for matching
The sample range of SCM system.
Further, the bandage type fabric electrocardioelectrode, bandage both ends are golden fabric, and centre is conductive fabric structure
At cover.
The beneficial effects of the invention are as follows:
The present invention uses conductive fabric as ECG monitor terminal, and devises ECG Gathering System, by fabric formula electrocardioelectrode
Collected faint electrocardiosignal is further amplified and is filtered, to obtain the stabilization ecg wave form of patient's high s/n ratio.
Description of the drawings
Fig. 1 is the EGC analog front end modulate circuit structure chart of the present invention.
Specific implementation mode
It is further described in detail presently in connection with attached drawing.
As shown in Figure 1, wearable electrocardio monitoring system, is improved by bandage type fabric electrocardioelectrode, EGC analog front end
Circuit and SCM system composition, the bandage type fabric electrocardioelectrode, bandage both ends are golden fabric, and centre is that conduction is knitted
The cover that object is constituted;EGC analog front end modulate circuit includes buffer amplifier 1, AC ac-coupled circuits 2, right leg drive electricity
Road 3, magnifier 4, high-pass filter 5, low-pass filter 6, the bis- T trappers 7 of 50Hz and post-amplifier 8;Bandage type
Fabric electrocardioelectrode extract human ecg signal, connect behind electrode a buffer amplifier 1 convert high impedance signal to it is low
Impedance signal;The electrocardiosignal extracted is efficiently couple in subsequent signal processing circuit by AC ac-coupled circuits 2;Instrument
Table amplifying circuit 4 is amplified two paths of differential signals, by high-pass filter 5, low-pass filter 6 and the bis- T trappers of 50H
After 7 processing, two level amplification is carried out by post-amplifier 8 to the signal of processing, electrocardiosignal amplitude is amplified to volt rank, is used
In the sample range of matching SCM system.
The foregoing is merely the schematical specific implementation modes of the present invention, are not limited to the scope of the present invention.It is any
