Description
Technical field
The invention belongs to Intelligent worn device field, particularly to a kind of intelligent watch for ECG detecting.
Technical background
Electrocardiogram (ECG) can be used to record the heart electrical activity that cardiac cycle produces each time, and electrocardiosignal can be by
The potential difference of measurement two different parts of body surface obtains, and can obtain the heart rate value of human body, electrocardiosignal using electrocardiogram
It is united acquisition human bloodstream speed with pulse signal, reflect pressure value；Analysis electrocardiogram, can be lost with the assisted diagnosis rhythm of the heart
Often；The position of assisted diagnosis heart disease；Help analyze the impact to heart for the medicine；Help analyze sleep quality etc..
Conventional ECG measuring method adopts electrocardiograph, and measuring point is various, including multiple Measurement portion such as extremity, chest
Position；Measuring electrode abundant species, conventional is Dispoable medical wet electrode, and such electrode advantage is that viscosity is strong, and collection signal is clear
Clear, strong antijamming capability, shortcoming is not reproducible utilization, easily causes skin allergy.Electrocardiograph volume is big, is therefore inconvenient to take
Band, for the portable electrocardio measurement service providing, many wearable product designs electrometric function of the heart, include electrocardio survey
Amount bracelet, electrocardio measurement wrist-watch, electrocardio measure pectoral girdle, possess the electrometric clothes of the heart, electrocardio breast patch etc..Wherein electrocardio measurement breast
With the electrocardiosignal in measurement user chest, advantage is to monitor for a long time, and shortcoming is that wear comfort is poor；Using dryness metal electricity
The pectoral girdle of pole, during wearing, electrode displacement is big on measurement result impact, using the pectoral girdle of wet electrode, because wear time is long,
Easily skin is damaged.Possess the electrometric clothes of the heart, have multiple measurement scheme, one kind is that pectoral girdle is the same adopts with electrocardio measurement
Measure the electrocardiosignal in user chest with dryness metal or wet electrode, the program is similar with pectoral girdle pluses and minuses；Another kind of scheme is
Using non-cpntact measurement scheme, place condenser type electrocardio sensing in the specific part (chest, right shoulder of left shoulder etc.) of wearable garment
Device chip, measures electrocardiosignal, the user experience of the program is good in the case of not contacting user's skin, but non-at present connects
Tactile thought-read power technology is still immature, and electrocardio measurement signal quality compares that contact type measurement is poor, and therefore the program is at present also in general
Read the stage.More electrocardio wearable device is used to measure bracelet and electrocardio measurement wrist-watch for electrocardio at present, this kind equipment passes through to survey
Amount user wears the wrist of handss and the potential difference of another handss, thus obtaining electrocardiosignal, this kind equipment and pectoral girdle or electrocardio
Measurement clothes compares it is not possible to continuous measure, and therefore real-time is not high, but because wrist-watch or bracelet wearing mode are simple, just
The property taken is compared other class product forms and is had more advantage；Wrist-watch is with respect to bracelet kind equipment, because possessing display screen, can conveniently carry out
Electrocardiogram real-time monitored, therefore with respect to bracelet kind equipment, electrocardio measurement wrist-watch is more convenient to use；Watch kind product electrode form
Using dryness metal electrode, due to dryness metal electrode to displacement sensitivity, different materials, different area metal to measurement result
All have an impact, the therefore design of dryness metal electrode has a very big impact to electrocardio measurement wrist-watch measurement result.
But the electrocardio wrist-watch first having is to improve clarity of signal, reduce noise, generally adopt three metal electrodes, respectively
Connect left hand, the right hand and " right lower limb ", " right lower limb " refers to remaining body in addition to left hand electrodes, right hand electrode contact position
