Description
Technical field
The present invention relates to a kind of miniature electrocardio measurement card.
Background technology
At present, heart disease has been one of fatal rate highest disease in the world, have it is sudden it is strong, the incidence of disease is high, multiple
The features such as hair rate is high, complication is more.Heart disease is the general name of heart disease, including rheumatic heart disease, congenital heart disease, height
Blood pressure heart disease, coronary heart disease, myocarditis etc..Because heart disease has sudden, sporadic, many times patient feels body
It can not be seen a doctor in time during situation exception or when disease is sent out, the impression of body when can only be sent out Xiang doctor's statement is sick afterwards, that is done is normal
Rule ecg wave form is also and without exception, and the diagnosis for being difficult to doctor makes reference.
Traditional medical ECG monitor, its Technical comparing is perfect, and accuracy of detection is higher, but volume is larger, takes empty
Between it is larger, up to 8, electrode, patient must could complete the monitoring of electrocardiogram with the help of professional, therefore, operation not
Just, it is impossible to measure the ecg wave form of patient whenever and wherever possible.Existing family expenses pressure electrocardio measuring device, operate relatively simple, Ke Yifang
Put and use at home；But because its internal structure is complicated, product shows slightly thick and heavy, length is about 20 ~ 40 cms, and weight is about
400 ~ 1000 grams or so, it is impossible to carried with as card, patient can use when disease is sent out at home, but out of doors using not
Just.
Existing portable cardiac equipment in the market, some can be reduced its length, width within 20 centimetres,
But due to the part space-consuming such as circuit board and display screen is larger, for its thickness at least between 2 ~ 3 centimetres, carrying is not too
It is convenient.It is usually the electrocardio Special single-core piece using foreign import in the solution of this kind of product, such as U.S.'s ECG electrocardiograms
HRV chips BMD101, above-mentioned chip inlet is full-featured, measurement accuracy is higher, but its price is costly, therefore causes such
The production cost and price of product are higher, and market price is larger for some economic pressures typically more than 1000 yuans
For patient, price is difficult to bear.
In outdoor or public arena, patient generally requires to enter in time in the case where palpitaition occur or the symptomatic condition such as being short of breath
Row measurement ecg wave form, existing household pressure electrocardio measuring device, portable pressure electrocardio measuring device due to finished-product volume it is larger, with oneself
It is inconvenient to carry, the service of measurement ecg wave form can not be provided for patient at any time.In addition, existing portable cardiac functions of the equipments
It is relatively simple, except electrocardio monitoring function, do not have other functions.
In addition, existing some intelligent health products, such as Intelligent bracelet, declare can heart rate measuring, actually using anti-
Penetrate formula optical principle, can only measure pulse rather than heart rate, and can not follow-on test, can only tap and test, or often
Every a few minutes test once, what is tested is all discrete data, rather than real-time continuous data, operation inconvenience, measurement essence-degree
It is relatively low, in some cases, under patient's low blood pressure extremely serious situation, or even Validity Test can not be realized, can not be to heartbeat
Speed and regular interval do a preliminary judgement, the physical condition of user can not be made comparisons and accurately commented
Estimate.
