Embodiment 1：

As shown in Figure 1, the conventional stethoscope that the prior art is includes chest piece, sebific duct, ear piece；Chest piece includes can, can connection Part, chest piece are stethoscopic pickup components；Ear piece includes syrinx, earplug, spring leaf, and syrinx and earplug all have two, earplug Mounted on pleasant one end of syrinx, the other end of syrinx is mounted on spring leaf, and ear piece is stethoscopic to listen sound component；Chest piece It is connected by sebific duct between ear piece, can is connected by can connector with one end of long length hose, the other end tool of long length hose There is integrally formed branch or be connected with threeway, branch is connected by extended sebific duct with syrinx, and threeway passes through short sebific duct and syrinx It is connected；

It is medicine, clinical medical common-sense content, and in phase about the detailed construction of conventional stethoscope and use, stethoscopy It closes and is expressly recited in teaching material, so it will not be repeated.

As shown in Fig. 2, facilitate described in the present embodiment the multidigit of placement and switching point multichannel input stethoscope, the can and Can connector have it is multiple, long length hose be equipped with sound channel switch；The sound channel switch have it is at least one outlet and with The entrance of can equal amount, outlet are connected by short sebific duct with ear piece, and entrance is connected with multiple cans respectively by long length hose； Sound channel switch is established for one or more of multiple entrance sound channels sound channel to be connected with outlet between can and ear piece Sound passage.The function of above-mentioned sound channel switch is that multiple cans are conducted next biological sound signal one by one or simultaneously will Multiple signal switchings are conducted to stethoscopic ear piece, and doctor makes diagnosis accordingly.

Stethoscopic material plays an important role on the audio that auscultation biology sound conducts, and sound passes through air or object Matter is propagated, and thermal energy disappearance is eventually converted into.The transmission of sound wave, almost without decaying in heavy metal, in lighter metal or modeling Decaying is susceptible in material, thus, high-grade stethoscope must use the heavy metals such as stainless steel even titanium.Stethoscopic conducting part Point --- acoustic pipeline is also critically important, and the internal diameter of pipeline is bigger, length is shorter, tube wall is thicker, and stethoscopic effect is better, international Full-length is 27 inches.The material of modern stethoscopic acoustic pipeline is generally PVC, and audio is good, beautiful, but stretch-resistance Difference often easily snaps off after bending, stretching.Stethoscope should hang on neck both sides by she is open and flat after use, this is in foreign countries It is visible in TV play, it is to wear high-quality stethoscopic standard method.Therefore, the sound channel switch preferably uses mechanical structure Device, with the best results of metal, particularly heavy metal.For the concrete structure of sound channel switch, below in an example It is described in detail.

Further, as shown in Fig. 2,8, the can has 5, respectively corresponding following five cardiophony areas：

A --- auscultation area of aortic valve

The second area of auscultation of A2 --- aorta petal

P --- pulmonary valve auscultation area

M --- auscultatory mitral area

T --- tricuspid valve area of auscultation.

Auscultation is to try to find out the sound voluntarily sent out in human body with ear or stethoscope.It is chiefly used in hearing the rhythm of the heart, breath sound etc..Often Stethoscope has collection sound effect, while also having filter action.By auscultation, characteristic and variation that doctor can be according to sound （Frequency height, power, interval time, the noise of such as sound）To diagnose related internal organs, whether there is or not lesions.Heart sound（heart sound）Refer to and is hit caused by vibration caused by ventricle wall, main artery wall etc. by myocardial contraction, heart valve closing and blood Sound.It can be listened at the certain position of the wall of the chest with stethoscope, it is also possible to the mechanical oscillation of the instrument records heart sound such as energy converter, referred to as Caardiophonogram.The sound generated when heart contraction diastole can be heard with ear or stethoscope in the wall of the chest, also under available electron instrument record Come（Caardiophonogram）.First heart sound can be divided into（S1）Second heart sound（S2）.（It can hear under normal circumstances）.(S3 is logical for third heart sound Often can only be heard in children and teenager), fourth heart sound（S4 normal conditions are rarely heard）.The heart sound generated from heart passes through group Wall of the chest surface is passed in the mediation knitted, wherein best with osteoacusis, blood and muscle take second place, and lung and adipose tissue are worst, so It compared with normal person is light that pulmonary emphysema and fat patient, which listen the heart sound recorded from the wall of the chest, and amplitude is low.Normal heart is in easypro contracting activity The heart sound frequency of generation is 1~800Hz.People's sense of hearing than it is more sensitive be the wherein frequency band of 40~400Hz, 20Hz vibrations below Human ear is not heard.Intensity of heart sounds, frequency and correlation can reflect the situation of heart valve, myocardial function and intracardiac blood flow.Often Four heart sound can be generated one cardiac cycle, what can generally be heard is the first and second heart sound.

First heart sound is happened at the systole, indicates ventricular systolic beginning.At apex beat（The 5th intercostal of the preceding wall of the chest On the inside of gap left mid-clavicular line）Listen most clear.Its tone is relatively low（40~60 hertz）, the duration is longer（0.1~0.12 second）, It relatively rings, ventricular contractility is stronger, and first heart sound is more rung.It is generated：

First, when due to ventricular contraction, blood flow quick-blow atrioventricular valve and caused ventricle wall vibrations of turning back；

Second is that since atrioventricular valve is closed, vibrated caused by valve leaflets and chordae tendineae anxiety etc.；

It is vibrated third, blood is projected from ventricle caused by hitting aorta wall and pulmonary arterial wall.

Second heart sound is happened at the diastole, indicates the beginning of ventricular diastole, it is divided into aorta sound and pulmonary artery tone Two ingredients, respectively in aorta and pulmonary artery area of auscultation（The breastbone right side, the second intercostal space of left border）Listen most clear.It is by leading Arterial valve and pulmonary valve are closed rapidly, and blood flow impact makes aorta and pulmonary arterial wall root and core indoor wall vibrate and produce It is raw.Its tone is higher（60~100 hertz）, the duration is shorter（0.08 second）, loudness is weaker.Its power can reflect aortic pressure With the height of pulmonary arterial pressure, angiosthenia increases, then second heart sound is hyperfunction.

Third heart sound is happened at after second heart sound, is continued shorter（0.04~0.05 second）, tone is relatively low.It is in ventricle Diastole early stage, with the opening of atrioventricular valve, the blood of atrium and pulmonary vein flows rapidly into ventricle（Before atrium is not contracted）, cause the heart The vibration of locular wall and chordae tendineae and generate.It can be heard in the young people of most of children and about half, it does not necessarily imply that abnormal.

Fourth heart sound is happened at the low-frequency vibration before first heart sound, lasts about 0.04 second.It is due to atrial contraction, blood flow is fast Vibration caused by the full ventricle of speed, also known as atrial heart sound.Most of normal adults can be recorded low small by caardiophonogram Four heart sound, general auscultation are difficult to find.

After lesion occurs for heart valve, valve can be made abnormal vibration and the change of blood flow occur, generate abnormal heart sound, Satisfactory noise.It can clinically assist to diagnose certain angiocardiopathies according to the period and property that heart murmur generates.

Stethoscope has two kinds of chest pieces：Diaphragm type, suitable for the sound for listening frequency high, such as the diastole of aortic incompetence Noise.Bell, suitable for listening low-frequency sound, such as third heart sound（Abbreviation S3）, fourth heart sound（S4）, mid-diastolic rumbling murmur Deng.When auscultation auscultation is carried out in each auscultatory valve areas in order.

The area of auscultation proposed in 1964, including seven parts：

1. aortic area crosses to the right manubrium by left border of sternum third intercostal, expands to the first, second and third rib of right border of sternum Between, right subclavian area, fovea jugularis, right neck extend down into apex, S-shaped.This area is equivalent to aortic root and portion Decilitre aorta, and be not limited to aorta petal itself；

2. pulmonary area is expanded upwards to the first intercostal, area under left clavicle, to down toward chest centered on the second intercostal of left border of sternum Bone left border third intercostal expands to the right fourth, fifth 2~3cm of thoracic vertebrae both sides.This area is equivalent to pulmonary artery and is not limited to pulmonary artery Valve；

3. atrium dextrum area, fourth, fifth intercostal of right border of sternum extends to the right 1~2cm, is the conduction of tricuspid insufficiency noise Area；

4. right ventricle area, to commonly use tricuspid valve area（Fourth, fifth intercostal of left border of sternum）Respectively expand 2cm to the left and right, right ventricle significantly expands When big, expand to the left to normal apical region of heart.This area's range is wide, and variable compared with tricuspid valve area；

5. left ventricle area, centered on apex beat, 2cm in fourth, fifth intercostal horizontal direction, out to left anterior axillary line.This area compared with Mitral area is big, also variable；

6. atrium sinistrum area is located at the left of spine of angulus inferior scapulae level, posterior axillary line is extended to, to listen mitral valve insufficiency miscellaneous The good position of sound；

7. descending aorta area is limited to the 2nd~10 thoracic vertebrae and extends 2~3cm to the left.This area easily finds aortic coaractation and active The noise of arteries and veins tumor.

Heart valve area of auscultation usually has 5：

1. mitral area：Positioned at apex beat point of maximum intensity, also known as apical region of heart；

2. pulmonary area：In the 2nd intercostal of left border of sternum；

3. aortic area：Positioned at the 2nd intercostal of right border of sternum；

4. the second area of auscultation of aorta petal：In the 3rd intercostal of left border of sternum, the also known as areas Erb；

5. tricuspid valve area：In breastbone lower end left border, i.e. left border of sternum the 4th, 5 intercostals.

Common auscultation sequence can be since apical region of heart, counterclockwise auscultation successively：Apical region of heart is first listened to listen lung dynamic again Then the areas Mai Ban are aortic area, the second area of auscultation of aorta petal, are finally tricuspid valve areas.Some clinicians also have from Heart bottom starts to carry out the auscultation of each valve area successively.

It should be pointed out that these common auscultation regions assume that cardiac structure and it is normotopic in the case of set , when cardiopathic cardiac structure and position change, the direction of the characteristics of need to being changed according to cardiac structure and blood flow are fitted When mobile auscultation position and expand auscultation range, specific area of auscultation is still taken for the heart disease of certain cardiac structures exception Domain.

Based on the stethoscopic design feature of more cans described in foregoing description and the present embodiment, the can be 5-7 A, or be adjusted according to handling characteristics, the custom etc. of specific doctor, the above-mentioned restriction to can quantity is not construed as pair The limitation of " more cans " this narration, and should be appreciated that carry out adaptability according to the development of doctor's individual demand, medical technology Adjustment, and the adjustment has no effect on the application interest field claimed.For example, in auscultation lung breath sound, religion 20 several auscultation positions are provided on section's book, but generally in clinical position, we are that the auscultation of selectivity is several than heavier The position wanted.You can carry out according to the following steps：

1,1-2cm below nipple, from outside to inside, 2-3 place of auscultation；Notice that pulmo will be listened, and compare breath sound to be It is no different；

2, arcus costarum（The camber line that rib cage bottom is formed）Top is base of lung portion here, patient is allowed to deeply breathe, carefully listen, there is pneumonia Or the patient of heart failure, it can usually hear " rale " here, sound when exactly breathing as bubble；

3, in addition, on tracheae throat, clavicle, between the clavicle of both sides, it can also listen and just listen.If back, also at arcus costarum It selects several places to listen to just listen.
