Description

Phone transmits the circulation memory electrocardiogram monitor

This utility model relates to a kind of medical monitor, and particularly a kind of phone transmits the circulation memory electrocardiogram monitor.

When the cardiac of not rare of short duration cardiopalmus, discomfort uncomfortable in chest or chest pain arrived in hospital admission, the state of an illness was often alleviated, and the doctor can only diagnose according to patient's narration, very easily causes affecting adversely of the state of an illness.For this reason, some hospitals with good conditionsi adopt the Holter electrocardiogram, and this Holter electrocardiographic monitoring is subjected to the qualification of time, thereby is not suitable for sporadic ARR diagnosis, and costs an arm and a leg, and practicality is subjected to certain influence.For addressing the above problem, the various miniature electro-cardiographs that pick up electrocardiosignal are come out one after another, but since its can only be after abnormal conditions appear in patient's heart implementation and operation, be difficult to reflect the overall process that abnormal heart rhythm changes, and the various signals that instrument write down can only carry out fax and send back to and put on electrocardiograph.For this reason, American I nstromedix company has developed the phone electrocardiogram monitor King for hearts 600 type products with circulation memory, four the button controls operations of this electrocardiogram monitor by being complementary with function, and transmit the ECG simulator signal in real time by phone, but this electrocardiogram monitor complicated operation, delivery quality is difficult to assurance, and can't write down the definite time of morbidity, and the accuracy of diagnosis still is subjected to certain influence.

The purpose of this utility model is: provide a kind of and both can transmit in real time, can remember playback again, portable phone by human computer conversation's operation transmits the circulation memory electrocardiogram monitor, it can be by telephone contact, patient is carried out remote long-term cardiac monitoring continuously, and write down the definite time of obtaining ecg information.

Another purpose of the present utility model is: a kind of portable real-time transmission or memory playback circulation memory electrocardiogram monitor by human computer conversation's operation is provided, by the electrocardiosignal of direct transmission, patient carried out closely long-term cardiac monitoring continuously.

Task of the present utility model is achieved in that by housing recorder is formed phone and transmitted the circulation memory electrocardiogram monitor, is provided with liquid crystal display on the housing, news Chinese percussion instrument and pair of control button.Recorder selects circuit and frequency interleaved modulation modulator to form by high-performance ECG amplifying circuit, A/D converter, D/A conversion and filter circuit, microprocessor, solid-state memory, channel switching.The input of high-performance ECG amplifying circuit and the electrocardio input socket that leads links to each other, and lead human ecg signal that socket obtained of electrocardio input is treated to and can makes the analogue signal of transmission in real time; A/D converter carries out mould/number conversion to analogue signal, to gather electrocardiogram (ECG) data; D/A conversion and filter circuit carry out D/A switch and filtering smoothing processing to the storage electrocardiogram (ECG) data of playback operation; Solid-state memory is to deposit the electrocardiogram (ECG) data of collection; Microprocessor links to each other with the pair of control button with liquid crystal display, and by liquid crystal display display command state and execution result, the operation control knob can judge, and finishes the human computer conversation; Channel switching is selected circuit, and its outfan directly links to each other with electrocardio output signal socket, so that the electrocardiosignal that need export according to command selection; The outfan of frequency interleaved modulation modulator directly links to each other with the news Chinese percussion instrument, ECG simulator signal frequency modulation is modulated into the frequency modulation signal of telecommunication that is directly proportional with signal level.Simultaneously, by the news Chinese percussion instrument signal of telecommunication is done electroacoustic conversion after, realize that by public telephone network DR telephone transmits with acoustical signal.

Another task of the present utility model is achieved in that by housing recorder is formed phone and transmitted the circulation memory electrocardiogram monitor, is provided with liquid crystal display on the housing, electrocardio output signal socket and pair of control button.Recorder selects circuit and frequency interleaved modulation modulator to form by high-performance ECG amplifying circuit, A/D converter, D/A conversion and filter circuit, microprocessor, solid-state memory, channel switching.The input of high-performance ECG amplifying circuit and the electrocardio input socket that leads links to each other, and lead human ecg signal that socket obtained of electrocardio input is treated to and can makes the analogue signal of transmission in real time; A/D converter carries out mould/number conversion to analogue signal, to gather electrocardiogram (ECG) data; D/A conversion and filter circuit carry out D/A switch and filtering smoothing processing to the storage electrocardiogram (ECG) data of playback operation; Solid-state memory is to deposit the electrocardiogram (ECG) data of collection; Microprocessor links to each other with the pair of control button with liquid crystal display, and by liquid crystal display display command state and execution result, the operation control knob can judge, and finishes the human computer conversation; Channel switching is selected circuit, and its outfan directly links to each other with electrocardio output signal socket, electrocardiosignal directly can be sent into cable link, and patient is realized closely long-term cardiac monitoring continuously.

This utility model can adopt control knob to finish the human computer conversation owing to adopted liquid crystal display and the pair of control button that links to each other with recorder, and by liquid crystal display display command state and execution result; In addition, can also in the record ecg information, write down the definite time of obtaining information, for definite diagnosis provides reliable foundation;

Be equipped with solid-state memory, and news Chinese percussion instrument that directly links to each other with the outfan of frequency interleaved modulation modulator or the electrocardio output signal socket that links to each other with the channel switching outfan, both can do remote real-time monitoring or memory playback to the analog electrocardiogram signal by phone, can do closely to transmit by cable link again, thereby realize the all-weather monitoring.
