Description
Technical field
The present invention is a kind of multichannel collecting device for being used to position extraction human body cardiechema signals.
Background technology
At present, cardiovascular disease is whole world morbidity and mortality highest disease, constitutes about overall 1/3rd
Left and right, the ratio in developed country and area is higher, and its death rate is 40% or so.Cardiechema signals are a kind of weights in human body
The physiological signal wanted, cardiophony are one of important methods of heart disease Non-invaive examination, in reaction heart murmur and disease in time
There is the advantage that electrocardiogram, ultrasound electrocardiogram, nuclear magnetic resonance, radionuclide and angiocardiography etc. are not replaced in terms of change.
Electronic auscultation device gathers heart sound by heart sound transducer, and signal then is transported into processor is analyzed and processed.At present, it is sharp
Common method with electronic auscultation device detection heart sound is to carry out signal acquisition with being held by heart sound transducer, and is each time
Can be in auscultation station acquisition heart sound all the way.
Torso model body surface has 4 area of auscultation:Auscultation area of aortic valve, pulmonary valve auscultation area, tricuspid valve area of auscultation and
Auscultatory mitral area.In order to carry out the quick detection of lossless positioning to heart sound, intelligent auscultation is realized, it is necessary to design new more
Passage heart sound synchronization positioning acquisition device.The invention mainly relates to a kind of 4 passage heart sound synchronization positioning acquisition devices, the device energy
4 area of auscultation of corresponding torso model body surface, synchronous 4 road cardiechema signals of monitoring in real time, are analyzed available by computer intelligence
Heart focus point corresponding to ill heart sound, disclose the relation of heart sound data and cardiomotility.The early stage for instructing heart disease is examined
Disconnected, treatment, a kind of new equipment that human body cardiechema signals are carried out with intelligent auscultation is provided for the increasingly mature network platform.
The content of the invention
The problem of existing for prior art, it is a kind of for positioning extraction human body cardiechema signals the present invention seeks to design
Multichannel collecting device.The technical scheme is that：A kind of 4 passage heart sound synchronization positioning acquisition devices, according to torso model
4 area of auscultation " auscultation area of aortic valve, pulmonary valve auscultation area, tricuspid valve area of auscultation and auscultatory mitral area " of body surface, use
The light elastic material such as metal or plastics makes the base of a heart shape, is shaped like human heart, but than the actual heart
A dirty big circle；Base front surface, corresponding 4 area of auscultation in this heart shape are provided with 4 heart sound transducers；This is heart-shaped
The base back surface of shape indicates 2 position lines, and one is the position line for corresponding to left side neck lateral edges, and one is under corresponding sternal body
Position line of the nearly xiphoid-process slightly at center or pit of the stomach is held, the position line passed through adjusts heart shape base to ensure 4 hearts on base
Sound sensor can be accurately placed on 4 area of auscultation, and appropriate plus-pressure makes heart sound transducer and human heart position
It is in close contact, to obtain optimal heart sound；Heart shape base edge is added with a circle acoustic material, with isolated background noise.
The cardiechema signals that 4 passage heart sound synchronization positioning acquisition devices obtain are filtered by No. 4 amplifiers, are output to after amplification
Computer, the process of heart sound activity corresponding to heart sound is obtained by the analysis software of computer, and particularly ill heart sound is corresponding
Heart focus point, that is, determine heart murmur be who in aorta petal, pulmonary valve, tricuspid valve and bicuspid valve caused by.
Multichannel, positioning acquisition and analysis, the device knot are carried out to cardiechema signals the invention has the advantages that can facilitate
Structure is reasonable, and using simple, a kind of new monitoring device is provided for intelligent auscultation.
Brief description of the drawings
Fig. 1 is 4 area of auscultation of heart body surface.
Wherein, 9 be pulmonary valve auscultation area, and 10 be auscultatory mitral area, and 11 be auscultation area of aortic valve, and 12 be tricuspid valve
Area of auscultation, 6 is correspond to the position line of left side neck lateral edges, and 7 be to correspond to the nearly xiphoid-process in sternal body lower end slightly at center or pit of the stomach
Position line.
Fig. 2 is 4 road heart sound synchronous acquisition devices of the embodiment of the present invention.
Wherein, the 1 first heart sound sensor installed for corresponding pulmonary valve auscultation area, 2 pacify for corresponding auscultatory mitral area
The second heart sound sensor of dress, the 3 third heart sound sensors installed for corresponding auscultation area of aortic valve, 4 listen for corresponding tricuspid valve
The fourth heart sound sensor of area's installation is examined, 5 be base, and 6 is correspond to the position line of left side neck lateral edges, and 7 be corresponding sternal body
Position line of the nearly xiphoid-process in lower end slightly at center or pit of the stomach, 8 be acoustic material.
Embodiment
The present invention is made below in conjunction with the drawings and specific embodiments and being specifically described..
As shown in Figure 2, base 5 is made by light elastic materials such as metal or plastics, is shaped like human heart, but
