Description

The synchronous assistant diagnosis system of mobile phone ambulatory electrocardiogram

Technical field

The present invention relates to the dynamic electrocardiogram diagram technology, especially a kind of ambulatory electrocardiogram assistant diagnosis system.

Background technology

Ambulatory electrocardiogram (Dynamic Electrocardiography DCG) was initiated by U.S. Holter in 1949, so claim the Holter electrocardiogram again.Ambulatory electrocardiogram can confirm whether symptoms such as patient's cardiopalmus, dizziness, faintness are relevant with arrhythmia; Like extreme bradycardia, asystole, conduction block, ventricular tachycardia etc., this is most important, the most widely used reasons of present 24 hr Ambulatory EKG Monitoring.24 hr Ambulatory EKG Monitoring also are one of standardized methods of monitoring myocardial ischemia; But the overall process of 24 hours electrocardio-activities of DCG continuous record; Comprise the ecg data under the different situations such as rest, activity, dining, work, study and sleep; Can find ND arrhythmia of conventional ECG and myocardial ischemia, be the clinical analysis state of an illness, establish diagnosis, judge the important objective basis of curative effect.

DCG has become one of important diagnostic method of atraumatic inspection in the clinical cardiovascular field at present.Compare with ordinary electrocardiogram; But ambulatory electrocardiogram continuous record in 24 hours reaches about 100,000 times electrocardiosignal; Can improve like this non-standing arrhythmia; Especially cross the recall rate of arrhythmia and of short duration myocardial ischemia outbreak to one, therefore enlarged the scope of electrocardiogram clinical application.In checking process, the patient puts on after the recording box, can carry out daily Activities, like working, stroll, simple housework etc.But avoid violent sports, avoid contacting intensive magnetic field and electric field.In order to avoid the electrocardiographic wave distortion, disturbing too much influences diagnosis report.And the monitoring whole process require patient's log, by time sheet the crawler behavior state with relevant symptom.Because paper record is loaded down with trivial details and omission easily, this recording mode auxiliary diagnosis clinically is not an ideal, and synchronous effect is poor, and the diagnosis effect that therefore brings not is very accurate.

Summary of the invention

Poor for the journal record reliability that overcomes existing existing dynamic electrocardiogram diagram technology and synchronous effect, as to be unfavorable for later stage diagnosis deficiency, the present invention provides that a kind of reliability is good, synchronous effect good, be convenient to the accurate synchronous assistant diagnosis system of mobile phone ambulatory electrocardiogram of diagnosis of later stage.

The technical solution adopted for the present invention to solve the technical problems is:

Further, said smart mobile phone also comprises: the manual input module of daily record, can't Intelligent Recognition the time, manually import behavioral activity and relevant symptoms in order to system.

Further again; In the said motor behavior determination module, put with the gravity center of human body and to define three mutually perpendicular axles, with the X of three acceleration sensors; Y; Z axially indicates vertical, the forward direction and the side direction of human body, on three, has the signal output of quickening and slowing down based on the characteristic of walking, and various typical motion behaviors have the corresponding signal curve cycle.

Beneficial effect of the present invention mainly shows: paperless intelligent record behavior daily record, reliability is good, synchronous effect good, be convenient to the later stage accurately diagnoses.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is further described.

With reference to Fig. 1～Fig. 4; The synchronous assistant diagnosis system of a kind of mobile phone ambulatory electrocardiogram; Comprise wireless electrocardio module, said assistant diagnosis system also comprise have the GPS positioning function, barometer function, 3-axis acceleration sensing function and load the smart mobile phone of ambulatory electrocardiogram assistance application software, said wireless electrocardio module is connected through the bluetooth4.0 radio communication with said mobile phone; Said smart mobile phone is communicated by letter with remote server employing WiFi/3G and is connected

Said smart mobile phone comprises: the GPS message processing module, in order to confirm the current GPS positional information; The barometer module is in order to calculate current height above sea level; The 3-axis acceleration sensor module is in order to the human body motor behavior; Timing module in order to when judging that ambulatory electrocardiogram starts, picks up counting; The motor behavior determination module; In order to interval according to setting; And set the 3-axis acceleration sensor of typical motion behavior and the signal threshold value of GPS, judge the type of current behavior according to the measured value of current 3-axis acceleration and GPS, and recording storage is in behavior outcome record table; The data-base recording module is in order to storage ambulatory electrocardiogram and behavioral activity daily record record; Data communication module in order to after accomplishing timing, sends to remote server with the data of outcome record table.

Said assistant diagnosis system also comprises remote server.Said remote server receives and storage synchronous dynamic ECG signal (ambulatory electrocardiogram signal and behavior daily record signal) is used for clinical diagnosis.

Said wireless electrocardio module comprises EGC sensor, electrocardiosignal modulate circuit, electrocardiosignal buffer circuit and electrocardiosignal wireless transmission circuit; Said EGC sensor is connected with said electrocardiosignal modulate circuit; Said electrocardiosignal modulate circuit is connected with said electrocardiosignal buffer circuit; Said electrocardiosignal buffer circuit is connected with said electrocardiosignal wireless transmission circuit, and the electrocardiosignal of gathering is in real time passed through wireless network transmissions to smart mobile phone.
