Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly to a kind of phono collector.
Background technique
In human heart, sinoatrial node automatically, generate electric current with having the rhythm and pace of moving things, electric current is transmitted to the heart by the sequence of conductive tissue
Dirty each position, so as to cause the contraction and diastole of cardiac muscle cell.Certain approach and mistake are pressed by the excitement that sinoatrial node issues
Cheng Yici is transmitted to atrium and ventricle, causes the excitement of entire heart.Therefore, the electricity occurred in heart each section excited process becomes
Direction, approach, order and the time of change have rule.This biology Electrical change is anti-by conductive resistance value around heart and body fluid
Body surface is reflected, makes parts of body that regular Electrical change occur in each cardiac cycle.Limb is placed in guidance motor
The cardiac electric change curve that the appointed part of body or body records out becomes electrocardiogram.
Caardiophonogram shows heart sound and heart adventitious sound, noise figure.Caardiophonogram is to the form and frequency for determining heart murmur
Composition has great role, more can determine that the time of heart sound and noise, clearly distinguishes the sequence that certain heart sound occur, identifies week aroused in interest
Interim coherent continuous murmur.
Existing electrocardiogram and caardiophonogram still rest on the stage of manual reading of drawings, it is necessary to which the experience for relying on doctor can
The information of electrocardiogram or caardiophonogram is parsed, people need to hospital to carry out electrocardio or heart sound inspection, by professional to heart sound
The interpretation of figure and electrocardiogram, judges whether with heart disease or disease risk.
Auscultation and ECG examination are the fundamental approach of Diagnosing Cardiac disease.Electrocardiogram can provide heart rate, the rhythm of the heart and part
The information of cardiac structure, but it is weaker to the antidiastole ability of disease.Different heart diseases can be in similar Electrocardiogram Feature.
If electrocardiogram prompts left ventricular hypertrophy, the cause of disease may be hypertension, mitral regurgitation/narrow, aortic stenosis etc..At this time
If in conjunction with cardiac auscultation foundation can be provided to the identification of above-mentioned disease.Cardiac auscultation depends on the subjective experience of doctor, non-cardiac
The accuracy of the cardiac auscultation of specialist may be lower.And testing result is influenced vulnerable to external disturbance when ECG examination.
