Description

Wearable electrocardio monitoring system
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 Those skilled in the art, made equivalent variations and modification under the premise of not departing from design and the principle of the present invention, The scope of protection of the invention should be belonged to.
