Description

The microwave cardiac telemetry system
Technical field this utility model relates to medical diagnostic equipment, particularly the electrocardiosignal of human body is carried out a kind of cardiac telemetry system that very-long-range transmits and monitors.
Background technology heart disease is a kind of sudden and disease changeableness of having, and is very big to human health risk, is very important and obtain the ecg information of patient when morbidity timely and accurately to cardiopathic diagnosis and treatment.Generally speaking, the state of an illness gentlier or as yet is not diagnosed as cardiopathic patient, in the ordinary course of things, can shows normal electrocardio; , in case be subjected to the influence of certain factor, the patient will be the outbreak of paroxysmal ground, and electrocardio will show ANOMALOUS VARIATIONS; If can catch the electrocardio of this moment to change, be very important to patient's diagnosis and treatment.Particularly those have been diagnosed as heart disease, the one, because the state of an illness is lighter; The 2nd, because through after a while hospitalization, owing to the leave hospital patient and those patients who waits to make a definite diagnosis that are in of state of an illness respite is just all the more so.In view of above-mentioned, the research cardiac telemetry system is very important.Existing electrocardioscanner can roughly be divided into two kinds: a kind of is to adopt wireless mode, the cardioelectric monitor equipment of this mode, owing to be subjected to of the restriction of various countries corresponding radio regulatory agency about monitoring distance, can only in hospital, monitor the patient, can not take remote measurement.Another kind is to adopt the PSTN cable telephone network to transmit electrocardiosignal, though can realize like this patient is taken remote measurement, but because it is platform with the landline telephone, the patient still can not carry out remote measurement in time to patient's the state of an illness when trip or can not find under the situation of landline telephone for the moment; Both made landline telephone, and also, therefore, when bringing inconvenience, signal to noise ratio had greatly been descended to the patient because this mode is to adopt the mode of acoustical coupling that electrocardiosignal is coupled in the PSTN network to go.
The summary of the invention the purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, for the patient provides a kind of small and exquisite, easy to use and place microwave cardiac telemetry system that can take remote measurement in all case.
This utility model comes specific implementation by implementing following technical scheme: a kind of microwave cardiac telemetry system comprises that heart electrode and electrocardiosignal show recording equipment.Be connected with electrocardiosignal changer and mobile phone in turn in the heart electrode back, the signal receiving device of Microwave Net is connected with the electrocardiosignal restorer, and electrocardiosignal shows that the input of recording equipment connects this electrocardiosignal restorer.When needs of patients takes remote measurement to its electrocardio, heart electrode is affixed on the position of comprehensively leading of front, and heart electrode picks up electrocardiosignal, is transferred to the electrocardiosignal changer that is attached thereto, electrocardiosignal is amplified and frequency-conversion processing, signal is become be suitable for the signal that telephone network transmits; Transmitting terminal at ecg information, the signal that mobile phone will be loaded with ecg information is transmitted on the signal receiving device at Microwave Net receiving terminal (normally cardioelectric monitor center), and the electrocardiosignal restorer that signal receiving device connects is reduced to signal that the electrocardio of input back shows recording equipment after the ultra-low frequency electrocardiosignal.Again because mobile phone has sound-recording function, so, in some restricted places (relatively responsive to microwave signal on as airport, aircraft and in the hospital place), (mobile phone of some type has sound-recording function can to enable the sound-recording function of mobile phone, as: the cd928+ of Motorola, L2000 etc.), the electrocardiosignal record in mobile phone, is sent out when waiting to have ready conditions again.So just can realize whenever and wherever possible patient's electrocardio is taken remote measurement, for patient's diagnosis and treatment provide important reference.
This utility model is owing to implementing technique scheme, so have following characteristics:
1. have movably characteristics as the mobile phone of transmitting terminal and small electrocardiosignal changer, therefore, can carry.
2. can take remote measurement at any time, and not be subjected to the restriction of occasion, can greatly make things convenient for the patient.
3. the medical department of receiving patient's electrocardiosignal can be by the breath of sending short messages, voice mail or with modes such as the patient directly converses, instruct the patient to take best disposal method; This will make the patient obviously be benefited.
