Description
Technical field
The present invention relates to a kind of detection means and method, espespecially a kind of detection means for being used to detect heart murmur
And method.
Background technology
Heart murmur is the sound produced by a kind of intracardiac blood circulation, and these noises are probably blood in the heart
Dirty interior flowing produces sinuous flow and caused, it is also possible to abnormal caused in terms of heart or blood vessel.General
Heart murmur is broadly divided into two major classes, and the first kind is that functional murmur Equations of The Second Kind is pathologic murmur.Function
Property noise Producing reason includes：Periphery pulmonary stenosis, PDA, tricuspid valve closure are not
Congruence, and pathologic murmur Producing reason includes：Ventricular septal defect, valvular stenosis or incompetence,
Defect of atrium or ventricle compartment etc..Functional murmur is typically benign, harmless, and pathologic is miscellaneous
Sound due to be by cardiovascular extremely caused by, the typically sign of heart disease.
The intensity of heart murmur can be divided into one to six grade, and the first order is most weak, the 6th grade most strong.First order intensity
Noise beyond patient heartbeats is heard with stethoscope, fourth stage intensity is passes through by quiet environment traditional Chinese physician
Touch can feel the noise of vibrations, and the sound that stethoscope need not be close to the wall of the chest and can hear is the 6th grade.
The inspection of heart murmur, which is mainly, passes through stethoscope, when stethoscope is close to patient's wall of the chest, according to sound length,
Intensity and time, doctor can tentatively be studied and judged the relevant disease of heart, such as cardiac arrhythmia, the heart by heart murmur
Coating inflammation, valvular stenosis, prolapsus or insufficiency, ventricular heart septal defect, Dong Jing Mai Fistula pipes etc..
Traditional stethoscope mainly by copper, rubber tube, spring leaf and listens first-class material to constitute, and can be divided into：
The classes such as alone stethoscope, double-purpose stethoscope, triple change stethoscope, vertical stethoscope and universal stethoscope, are used
In patient of the varying environment from different situations.However, in today of medical science and technology progress, stethoscopic work(
Can be also more and more accurate, " electronic auscultation device " also comes out therewith.Traditional stethoscope is mainly collection sound,
And voiceless sound amplification effect, and electronic auscultation device has good volume numerical digit enlarging function, can understand and listen
To from the heart sounds by trouble of diagnosing a disease.
However, the detection of heart murmur usually can be sent sound by other human organs and be disturbed, such as
The breathing of lung.Common people's breathing can send sound, but noise occurs in expiratory dyspnea person, if lung
There is ponding obstruction in portion, and different noises more occur.The appearance of these noises, all can cause doctor sentencing
Read the puzzlement on heart murmur.Therefore, the situation that above-mentioned heart murmur is difficult to differentiate how is solved, actually at present
