Description
One, technical field
This utility model relate to a kind of clinical medicine, health care and sports field utilize mobile phone transmission heart vibration signal cardiac contractility ability variation tendency and changes in heart rate trend are carried out device for monitoring, particularly a kind of heart reservation instrument of mobile phone transmission heart vibration signal.
Two, background technology
still fail so far aspect the cardiac function diagnosis to develop more than the km level that can realize cardiac contractility ability (abbreviation mental and physical efforts) signal wireless transmission and with heart reservation test and appraisal equipment as major function.Existing monitor, for example the index of Japan's product ColinBP 88 multifunctional monitoring instrument detection includes only blood pressure, pulse, breathing, oxygen saturation, can not monitor myocardial contraction and heart reservation.And the subject matter of most of heart failure patients is reductions of myocardial contraction, in cardiovascular diseases diagnosis and therapeutic process heart variable force, chronotropic is monitored simultaneously and the assessment routine work that is very important.The early discovery myocardial contraction descends and in time takes measures has great realistic meaning to the control heart failure.The daily appraisal procedure of athlete heart function is to utilize some heart rate indexs, if can replenish some cardiac contractility ability indexs, just can do more fully to estimate to the athlete heart function.
About cardiac functional grading, New York heart association (NYHA) has proposed a cardiac functional grading scheme of extensive use (NYHA FC) in the world, but it is mainly according to medical history, does not have objective quantizating index.Proposed some modifications around this scheme again afterwards, replenished objective monitoring method but press for.Though cardiac catheterization is measured objective, the quantification of cardiac function, belonging to has the wound inspection, needs carry out under the sterile working, conduit room, and should not reuse.Multiple nothing wound property cardiovascular diseases's diagnostic instruments and cardiac function monitoring method have been arranged clinically.For example, at present, Electrocardioscopy is cardiac chronotropic and becomes conductive best monitoring method, but can not be used for monitoring the variable force of heart.Ultrasoundcardiogram can be by monitoring the functional status of cardiac muscle from relaxing period to the measuring and calculating of Syst intensity of variation and speed to chambers of the heart diameter, the electrocardio machine drawing to ventricle in the cardiac cycle each the time phase mensuration can do certain monitoring to ventricular function, but some index sensitivity is relatively poor; Sensitivity, the specificity of development of radionuclide painstaking effort pond and nuclear magnetic resonance are all high, but high price is expensive, are difficult to promote; Though it is objective, practical, reliable that maximum oxygen intake and anaerobic threshold mensuration belong to, but be subjected to the influence of respiratory function.
In the world about the research of heart vibration signal and cardiac contractility ability relation for addressing the above problem the approach that hinted.Because " size of first heart sound amplitude and cardiac contractility ability power are closely related " is so can monitor heart reservation, heart endurance with the variation tendency of first heart sound amplitude.Theory analysis shows, when the size of first heart sound amplitude depends mainly on ventricular systole the pressure that produces can size; And the size of this pressure energy is mainly decided by the power of myocardial contraction.Zoopery and clinical research show: " variation of the variation of first heart sound amplitude and left ventricular pressure rising maximum rate is proportionate ".But still fail fully research and utilization " mental and physical efforts and heart vibration signal relation " in instrument development and clinical practice.
" health care equipment " (2004; 25 (7)) report the result of study of " based on the realization of the physiological signal transmission of Bluetooth protocol ", had mental and physical efforts signal transmission potentiality, but transmission range limited (10m).
" Acta Biophysica Sinica " " (2004; 20 (5)) reported " comparative study that multiple trend of the mental and physical efforts of motion back mental and physical efforts and heart rate remote measurement simultaneously and heart rate recover trend ", have the mental and physical efforts signal transmission capabilities, but transmission range has been limited to 100m.
Utilize mobile phone transmission heart vibration signal, then can realize wireless transmission that the 1000m level of cardiac contractility ability signal is above and with the equipment of heart reservation test and appraisal as major function.The compatriots cellphone subscriber has exceeded 300,000,000, above-mentioned with heart reservation test and appraisal as the equipment of major function even can enter community and family, allow masses enjoy the heart reservation assessment method of reflecting myocardium contractility variation tendency and changes in heart rate trend simultaneously.
Three, summary of the invention
This utility model purpose is to provide a kind of handle to transfer to heart reservation test and appraisal personnel's mobile phone by user's mobile phone from the signal of heart vibration signals collecting module, repeated transmission is gone into computer, carry out the extraction and the analysis of mental and physical efforts signal and cardiac cycle signal with the heart reservation test and evaluation software, realize the noinvasive to cardiac contractility ability and heart reservation, the heart reservation evaluation system of objective quantification monitoring.
The purpose of this utility model is to realize like this, a kind of heart reservation instrument of mobile phone transmission heart vibration signal, include the hear sounds pulse transducer, heart vibration signals collecting module, the heart vibration signal sends mobile phone, the heart vibration signal receives mobile phone, computer, display, mouse, keyboard, printer, be characterized in being provided with a heart vibration signals collecting module, its input is connected with the outfan of hear sounds pulse transducer, the outfan of heart vibration signals collecting module is connected with the audio interface that the heart vibration signal sends mobile phone by holding wire, the heart vibration signal that is sent reaches heart vibration signal reception mobile phone by the communication system of used mobile phone, and the audio interface that the heart vibration signal receives mobile phone is connected with the audio input interface of computer by holding wire.
Press this utility model, testee's heart vibration signal carries out pretreatment through the preposition filter amplification circuit that is amplified into heart vibration signals collecting module to signal by the hear sounds pulse transducer, finishes filtering and amplification to the heart vibration signal.Enter amplifier through filtered heart vibration signal and amplify, the heart vibration signal after amplifying is sent into computer through the audio interface of heart vibration signal reception mobile phone by holding wire again by wireless transmission between mobile phone.The heart vibration signal is sent into memory stores behind the A/D converter digitized of machine as calculated.During work, the heart reservation analysis programme is to carrying out the extraction and the analysis of mental and physical efforts signal and cardiac cycle signal from the data of memorizer, and analysis result send display to show, and printable mental and physical efforts and rhythm of the heart report.
Owing to adopt such scheme, compared with prior art, have unique cardiac contractility ability and heart reservation monitoring function, but have simultaneously 1000m level above wireless transmission capability, noinvasive, sensitivity and specificity height, time limit measure can be accurate to Millisecond, easy, quick, low repeated using of cost and objective quantification, be suitable for sick bed other and and clinicist's diagnosis table on and characteristics such as the on-the-spot use of motion, and can enter community and family.The usefulness of the examination of the clinical cardiac function popularization of doctor, athlete heart function monitoring, scientific research and teaching can be provided.
