Description
Technical field
The present invention relates to a kind of electrocardioscanner, particularly relate to a kind of household electrocardiogram.
Background technology
Along with socioeconomic development, national life mode there occurs deep change.Especially the acceleration of aged tendency of population and Development of China's Urbanization, Chinese cardiovascular risk factors fashion trend is in the situation that obviously rises, and the number of the infected that result in cardiovascular diseases continues to increase.Report display according to 2014 Chinese cardiovascular diseasess, estimate that there is cardiovascular patient 2.9 hundred million in the whole nation at present, within 10 years from now on, cardiovascular diseases's number of patients will increase fast.Cardiovascular death accounts for the first place of the total cause of death of urban and rural residents, and rural area is 44.8%, and city is 41.9%.The Disease Spectrum of cardiovascular diseases day by day increases the weight of, and has become great public health problem, strengthens cardiovascular diseases and prevents work very urgent.Wherein find that early treatment effectively can reduce Hospitalized costs the morning of the disease such as coronary heart disease, arrhythmia, heart failure, improve the quality of life of patient.And the ECG detecting equipment of domestic to the timely detection of this type of disease, find particularly important.
For the portable cardiac detector of domestic, existing equipment is divided into two classes substantially in the market, and a class is the equipment of Wearable, as widely used in hospital 24 hours Holter, the ZIO Wearable ECG detector etc. of iRhythm company of the U.S.; An other class is the equipment of hand-held, surpasses the hand-hold electrocardioscanner that the companies such as think of, Omron produce as Beijing.
Need to stick ECG detecting electrode at trunk corresponding site when within 24 hours, Holter uses, the monitor then by being inclined cross gathers electrocardiogram (ECG) data, generally can the continuous acquisition electrocardiogram (ECG) data of 24 ~ 48 hours.In use procedure, patient will avoid strenuous exercise, prevents electrode delamination.After detection completes, monitor is given doctor by patient, and doctor reads and analyze by the software of specialty the data collected.
The ZIO of American I rhythm company only has two electrodes, only using in the senior private hospital of U.S. part at present, during use, ZIO only need be attached to chest by patient, opening power just can detect electrocardiosignal, similar with 24 hours Holter, the electrocardiosignal detected stores by ZIO, passes to doctor again to data analysis after waiting to be detected completing.Difference is that the continuous detecting time of ZIO is longer, can reach 1 week.In addition ZIO also has emergency alert function, once find that the burst of patient's heart disease will emergency alarm.
The electrocardioscanner of hand-held has a lot of manufacturer production at home and abroad, and its function is similar.During use, two handss only need be placed on the electrode at hand-hold electrocardioscanner two ends by patient, electrode starts test button just can detect electrocardiosignal, ecg wave form can be presented in the middle of screen, and some this series products can also do simple ECG detecting algorithm simultaneously.This kind equipment generally can only store the electrocardiogram (ECG) data of a few minutes.
Although existing equipment can detect electrocardiosignal on the market at present, there is its limitation.Within 24 hours, Holter accepts the most extensive in hospital at present, but patient does not like carrying, because its wearing is very inconvenient, limits the normal activity of patient; Simultaneously patient cannot the electrocardiosignal that collects of real time inspection whether effective, must etc. to be detected complete after just read by the software of specialty the electrocardiosignal collected, if the invalidating signal collected does not have remedial measure yet.
ZIO is easy to use, patient acceptance is very high, but is also just using in U.S. part hospital at present, and the cost of use of ZIO is very high, IRhythm company provides electrocardio long term monitoring to serve, and provides the examining report of specialty after having detected by backstage doctor after being detected.In addition similar with 24 hours Holter, patient equally cannot real time inspection EGC pattern, and whether cannot loosen by detecting electrode, whether the electrocardiosignal of collection is effective.
The maximum deficiency of hand-hold electrocardioscanner is that detection time is too short, can only detect the data of several minutes; Secondly, during detection, the contact of electrode and hands affects very large on testing result, and it is not very convenient to use; The data of this type of checkout equipment last can only leave this locality in, cannot send real-time for data to long-range doctor.
