Description
Technical field
The present invention relates to the Electrocardiographic instrument of a kind of transmission, relate in particular to a kind of short-distance wireless dynamic electrocardiograph and control method, belong to the medical apparatus and instruments of heart disease diagnosis monitoring based on GPRS.
Background technology
At present, the Incidence of CHD of American-European countries is more and more higher, becomes the principal disease of harm national health.Account for more than 64% of cardiovascular diseases's general mortality rate in the U.S., Canadian coronary heart disease death rate, annual about 700,000 people of the U.S. die from coronary heart disease, and wherein 65% is sudden death, and almost per minute just has 1 people's sudden death.The Incidence of CHD of China is a little less than American-European countries, but in recent years, raising and aged tendency of population along with living standards of the people, China's aging population have reached 1.32 hundred million, cardiovascular diseases's sickness rate and mortality rate all obviously increase, and become the principal disease of the harm people ' s health the same with tumor, report according to health: China has cardiovascular patient 7,000 ten thousand people now, just there is 1 cardiovascular patient in average per 5 families, and therefore the control to the cardiovascular diseases is a crucial problem.
The heart dynamic monitoring diagnostic device of clinical practice at home and abroad has two kinds of products, and a kind of is 24 hr Ambulatory EKG Monitoring recording systems (abbreviating HOLTER as), and a kind of is cardiogram transmitted by telephone system (being called for short TTM).HOLTER is applied to clinical existing 50 years history, and it is by recording box the electrocardiogram in the patient 24 hours all to be noted, and afterwards, utilizes microcomputer and software system to analyze, and draws 24 hours Electrocardiographic diagnosis reports.Because the data of HOLTER record are many, the time of playback and analysis, most hospitals required the patient to get the result in second day between 3-5 hour.In clinical practice,, occur the patient once in a while and in renting the process of HOLTER, diagnose, treat untimely and dead malpractice because of the HOLTER ECG change that can't in time note abnormalities.
The TTM system utilizes the Electrocardiographic equipment of fixed telephone line teletransmission, and the ECG data amount of its record is 1/6 of HOLTER, and the sectional record in time transmits.Compare with HOLTER, TTM is embodying superiority aspect the promptness of diagnosis, but can't equally with HOLTER realize Electrocardiographic quantitative analysis.Because TTM utilizes the Wireline of landline telephone to carry out the electrocardiogram transmission, the effective frequency of telephone line is 0-4000HZ, has limited Electrocardiographic transfer rate and place.In TTM clinical practice in recent years, the transfer rate of its data is slow, can't carry out two-way exchange with the doctor when abnormal electrocardiographic pattern occurs, defective such as can't use to embody gradually in the place that does not have landline telephone.
How to wear in the process of electrocardiogram dynamically recording equipment the patient, both can omnidistance recording ecg, can on monitor, observe electrocardiogram at a distance constantly again? both can the teletransmission electrocardiogram, can when sending recording box, the patient take diagnostic result again? how to make TTM realize both can transmitting whole electrocardiograms by fast recording, can use in any place again? can both both-way communications fast be realized the satellite fix tracking and monitoring of dangerous case again?
GPRS is that the English of GPRS (general packet radio service) (General Packet Radio Services) is called for short, it is a kind of new data service that development is come out on existing gsm system, purpose is the data service that block form is provided for GSM user, between mobile subscriber and data network, provide connection, provide high-speed radio IP or X.25 service to the mobile subscriber.GPRS adopts the wireless-modulated standard same with GSM, same frequency band, same burst structure, same frequency hopping rule and same TDMA (TimeDivision Multiple Access) data structure, and existing base station sub-system (BSS) can provide comprehensive GPRS to cover.Theoretical bandwidth can reach 172.2Kb/s, and the practical application bandwidth is approximately 40-100Kb/s, is fit to carry out big data quantity and transmits, and technology such as wireless protocols are ripe, and can share use.
