A kind of portable electrocardiograph
Technical field
This utility model belongs to armarium technical field, is specifically related to a kind of portable electrocardiograph.
Background technology
Along with economic and scientific and technical development, the disease that threatens human health life from infectious disease gradually transition be Chronic Non-Communicable Diseases, cardiovascular diseases is exactly one of current global main noninfectious.Expect the year two thousand twenty, the number dead because of cardiovascular disease such as heart diseases will break through 2,000 ten thousand, and China and other developing countries, also will welcome cardiopathic popular peak at that time.In China, the death being caused by cardiovascular disease has accounted for 40% left and right of total PMI, and people's health has been caused to great threat at present.This signal has caused people's attention at present, but compared with other diseases, cardiovascular disease outbreak has randomness, the feature such as sudden, dangerous, according to BJ First-Aid Station statistics most of patients because falling ill in family or working space can not obtain in time Illnesses Diagnoses and incured loss through delay rescue opportunity, thereby lost valuable life.Thereby people expect the life and health of a kind of portable Medical Instruments love oneself very much.
No matter the cardiovascular disease which kind of reason causes, disease progression all can cause that to later stage great majority structure and the physiological feature of electrocardio conducting tissue and cardiac muscle cell change, and these variations all can make its bioelectrical activity rule change, these variations can be transmitted to human body skin surface, therefore just can record the potential change of cardiomotility by being placed on the electrode of appropriate location, human body skin surface, and then formation electrocardiogram, for the clinical diagnosis of cardiovascular disease provides important evidence.Holland Leiden professor W.Einthoven of university has developed First electrocardiorecorder according to this principle exactly.Current cardiac monitoring equipment is mainly divided into conventional electrocardiogram equipment and holter monitoring two classes.Wherein conventional electrocardiogram equipment is mainly used in hospital, and this kind equipment can detect patient's pathological data in real time, continuously, for a long time, but it is often expensive, volume heaviness, be not easy to carry, be difficult under first aid state, carry out in time cardiac monitoring work, be not suitable for ordinary populace and use.And though holter monitoring price is relatively reasonable, be easy to carry about with one, also electrocardio that can real time record patient changes, can catch the potential heart disease ecg information of patient, but because it does not possess the function such as real-time analysis and demonstration, promptly in particular cases can not carry out timely diagnostic analysis to patient's electrocardiogram (ECG) data at some.
