Specific implementation mode
The present invention is further described with reference to the accompanying drawings and detailed description.
Currently, traditional stethoscope includes thin film, general doctor allows the film close on the skin of patient, so as to
To hear various sound that human organ is sent out, such as the sound of Heart tissue or the sound etc. of lung by ear.
But since most of the sound that human body or mammalian organs are sent out belongs to low-frequency sound, by people ear very
Difficult resolve minutiae, in addition, by the sound that stethoscopic film generates, due to being easy to be interfered by external environment, low frequency, in
Frequently, the sound of high frequency can all be transmitted to the ear of doctor by the vibrations of film, this just needs very abundant experience that could divide
It is that pathology sound or normal sound are also susceptible to erroneous judgement even if veteran doctor to discern hear.After all, according to
Micro-judgment by people is not very accurate and objective.
Although also occurring detection of electrons means at present, can also there is a problem of it is usual, this is because biorgan
The generation of sound be frequently subjected to the interference of extraneous sound, although traditional electronic equipment makes moderate progress, but be still difficult to
Meet the increasingly desirable requirement accurately detected.
In order to solve defect of the existing technology, the present invention provides a kind of hand-held heart sound diagnostic device, the equipment packet
It includes as shown in Figures 1 to 12, a kind of new Human Physiology sound monitoring device, which includes cumulative head 1, film 2, wherein institute
The cumulative head 1 stated is arranged on the surface of film, and sound-proof wall 21 is arranged in 2 surrounding of film.
The film 2 is the film with certain elasticity, or relies on extraneous sound and can conduct the material of sound.
The material of this conduction sound can be transmitted by the vibrations of itself, i.e., the general film is the material that can conduct sound
Texture at, or by film self vibration and conduct sound.General its of the film 2 easy tos produce resonance, therefore can also claim
For resonance membrane.The material of above-mentioned film generally uses plastics, PVC material or medical macromolecular materials composition or other
Material composition, these materials can be airtight, soft, by tensioning when flexible material, can also be stiff material,
As long as the material that can transmit sound all can serve as the film 2 of the present invention.Here so-called " film " is not Dan Zhiyi layers,
Can also be multilayer, this is also not meant to 2 very thin thickness of film, there is specific elaboration below.Because with such " thin
Film " is easy for the sound wave for generating vibration to be in air converted into the vibration of its own, while being transmitted to other matchmaker by air
It is situated between, i.e., these thin-film materials can form resonator system with the air in the closed space layer in its behind.Because film has centainly
Sound absorption function, the RESONANCE ABSORPTION phenomenon of generation is mainly internal damping loss when film makees body vibration, the resonance frequency of film
Rate usually has the function of fabulous absorption low frequency signal at 200 hertz to 1000 hertz, and human heart jumping frequency rate is every
Between minute 60 to 100 times, to the heart sound information that film energy good absorption is generated from human heart, and sealed with its behind
Air in the space layer closed forms resonance, achievees the effect that fabulous acquisition heart sound.
The cumulative head 1 is arranged in resonance membrane 2, and so-called cumulative head can be any material, as long as can transmit
The material of sound is all possible, such as wood, plastics, metal, alloy or other materials that can transmit sound.Preferred
Mode in, cumulative head is metal, for example, metals such as iron, aluminium, steel or alloy.For film, the thickness of cumulative head
Degree is greater than film, and the density of unit volume is more than the density of film.For example, when film is alloy sheet, cumulative head
It can be alloy head.When the equipment using the present invention containing cumulative head carries out the inspection of human body or the sound of mammalian organs
When survey, cumulative head and skin contact are allowed, and do not allow film contacts skin as far as possible, such as in the sound of detection heart
When, allow skin contact near cumulative head and heart, the sound that heart is sent out is by the skin transport near heart to cumulative
Head, the first voice transmission of cumulative is to film.We have surprisingly found that, using the film with cumulative head, sound can be amplified,
Especially some low-frequency sounds can obtain more fully sound monitoring.Here so-called that film discord skin is not allowed to connect as possible
Touch, can be least a portion of and skin contact, at least allow setting cumulative head position film discord skin contact, other places
Can and skin contact, or, it is preferred that allow film all to get along well skin contact, cumulative head only allowed to contact skin.
In some preferred modes, general cumulative head 1 is arranged in the middle position of film 2, can naturally also be arranged
The other positions of film 2, only it may be somewhat poorer in the effect of other positions, i.e., if in other positions, film 2 produces
Can cumulative head 1 be almost arranged in raw sound-absorbing effect such as on 2 side of film, and the heart sound absorbed will be difficult to cause entire thin
Film 2 is vibrated, to influence the effect that the air in the closed space layer in its behind forms resonance.Therefore, cumulative head 1 is to set
It is preferred plan to set in center.Film 2 can be any shape, such as round, diamond shape, rectangle, the shapes such as square,
In than more preferably mode, cumulative head is placed at the center of film, such as circle centre position, or the center of square,
Or it is other shapes of by paracentral position.
In some preferred modes, considers that phono is carried out while being acquired, circuit can be set on cumulative head 1
Electrocardiogram acquisition is carried out, and is connect with external electrocardiogram acquisition instrument, cumulative head 1 can be one or more at this time, and center is set
One is set, according to cumulative head 1 is arranged at the corresponding position of human heart key monitoring point on periphery, this can be preferably right
Monitored personnel carries out the condition monitoring of heart.When use cumulative head 1 for one when, in order to realize to being examined while electrocardio
Survey, cumulative head 1 be conductive conductor can, connect with cumulative head by circuit, to transmit electric current, while cumulative head 1
It also functions to collection and either detects the sound of the heart sounds collections and be amplified processing also by external equipment or sensor,
Electrocardio and heart sound are tested so all to realize by cumulative head 1, can reach while detect two kinds of indexs, point for carrying out while synchronizing
Electrocardio and heart sound are analysed, testing result is preferably obtained.Here cumulative head 1 takes into account two kinds of functions, so, cumulative head at least has
Conductive effect, so, cumulative head 1 has the function of conductor, for example, metal or other electrically conductive materials, here simultaneously
The material of not all composition cumulative head 1 is all conductor material, naturally it is also possible to non-conductive material and conductor material mixing composition
What cumulative head 1 also can be achieved on.
Certainly, for optional cumulative head 1 when having multiple on film 2, some of cumulative heads 1 are the use for detecting sound
On the way, cumulative head 1 in addition plays the role of detecting physiology electric current, such as electrocardio.Naturally, one can be arranged as needed
Change multiple spot monitoring, that is, multiple monitoring devices being made of 1, resonance membrane 2 of a cumulative head are set.This allows for each prison
Measurement equipment can carry out carrying out dynamic realtime monitoring to heart key monitoring position.I.e. above-mentioned monitoring device can be multiple one
It rises, is fixed by external fixed equipment, the hole of placement monitoring device, hole are provided in the external fixed equipment
Around on be provided with buckle limiting section, monitoring device only needs alignment buckle limiting section that can dispose, so as to facilitate
Together monitor human heart key several points, convenient for multiple spot simultaneously in real time monitor, to realize phono Simultaneous Monitoring,
Reach the heart of preferably feedback detected person.The external fixed equipment is using rubber material, medical high polymer material
Material or PVC material, because such material is convenient for fitting human skin surface, it is not easy to various not with the skin generation of monitored people
Suitable or allergic reaction.
The cumulative head 1 itself plays the role of focusing heart sound, and centre position effect has better amplification.I.e.
The cumulative head 1 includes bottom 11 and cumulative portion 13, and bottom 11 is contacted with film 2, cumulative portion 13 and sound to be detected
Organ contacts or mediate contact.In this way, sound is allowed directly or indirectly to obtain the sound of biorgan by cumulative portion 13, lead to
1 bottom conductive of cumulative head is crossed to film 2, film 2 generates vibration, so as to cause neighbouring air vibration, to conduct sound.
In preferred mode, the interference of external noise in order to prevent, cumulative head 1 is arranged in the side of film 2, the other side of film 2 with
The air of sealing contacts.
When allowing cumulative head 1 with skin contact, in order to avoid the interference of external sound, cumulative head 1 can be allowed to be in
Under one relatively quiet environment, such as in the outside of film 2 there is the fence structure of circle protrusion, the structure is around the side of film
Edge can be slightly lower than the height of cumulative head, and when allowing cumulative head to contact skin, the edge of raised enclosure wall also contacts skin
Skin, to surround cumulative head, to allow cumulative head to be in a closed space, reduce external sound to cumulative head transmit or
Collect the influence of physiological sound.I.e. sound-proof wall 21 is arranged in 2 surrounding of film, plays the effect of blocking external noise, it is described every
Sound wall 21 is generally preferred using annular shape, to which sound-proof wall 21 and skin form the wall of one and isolation external sound when in use
It builds, this will greatly reduce the influence of external noise.
The diameter of the bottom 11 than cumulative portion 13 diameter bigger, the bottom 11 be polygon or round, such one
It can easily just be fixed in resonance membrane 2, preferably cause the vibration with resonance membrane 2.This is preferred embodiment, naturally also
Can be big as the diameter in cumulative portion 13 with the diameter of bottom 11, relative to preferred embodiment in effect can slightly almost, but
It influences little.After the setting of cumulative head 1, with the skin contact of monitored people, the bounce sound of human heart can be by poly-
Can head 1 conducted, as soon as cumulative head 1 by sound monitoring gather at and use solid material, sound can be transmitted well
Come over, to conduct in upper resonance membrane 2, preferably to cause the air shape in the 2 closed space layer in behind of resonance membrane
At resonance effect.
Include a cavity containing air in some preferred modes, between cumulative head 1 and film 2.It is this containing free
The cavity of gas links together cumulative head 1 and film 2.In some modes, cumulative head 1 includes a hollow cavity, thin
The film covering cavity, to form the cavity for the air that one seals.As shown in Figure 1, the cumulative head 1 is using preferred side
After case, the structure that the four circumferential gradual protrusions in center form the first cavity 12 with film 2 may be used in the bottom 11 of cumulative head 1, this
A cavity is formed in cumulative in front, and open one end is by diaphragm seal.The mode of sealing is that cumulative head passes through glue etc. with film
Substance is bonded in also together.This structure allows for that the life sound collection of monitored people being conducted through come after by cumulative head 1, focuses
When to one, resonance effect can be formed because of the life sound of the monitored people of conduction to the first cavity 12, so as to cause shaking for film 2
It is dynamic.
The cumulative portion 13 of the cumulative head 1 is in bar shape, can also be conoid type, taper of falling from power, and cumulative portion 13 is polygon
Shape cylinder or cylinder all can, i.e., cumulative portion 13 is solid, is generally preferred using cylinder, because cylinder smooth treatment is convenient,
And it is that can form the mode for maximizing and being contacted with monitored application on human skin, this is conducive to completely to quilt in the case of same diameter
Monitor the collection of the heart sound of people.The cumulative portion 13 is in entire 1 highest point of cumulative head, thin higher than the resonance that cumulative portion 13 disposes
The 0.3cm to 4cm of 2 highest point of film, being generally higher by 1cm can.The height being higher by this way can form a focusing well
Convex, the periphery in cumulative portion 13 all not skin contacts with monitored human heart position so that connect with the skin of monitored people
Best resonance effect can be reached at this tactile.
If the bottom 11 that the cumulative head 1 uses can also select solid material, cumulative head 1 monitored in conduction
It can be relatively good on popular feeling sound.If cumulative head 1 is bonded completely with the center position of resonance membrane 2 at this time, film can effectively be inhaled
Low frequency signal is received, and generates vibration, but because of the gravity of cumulative head 1, can generally reduce the vibration that resonance membrane 2 can generate
Effect, more because the area that bottom 11 occupies resonance membrane 2 relatively can be more a little bigger than the diameter meeting in cumulative portion 13, therefore in effect
It can almost.Naturally, being bonded completely with the center position of resonance membrane 2 around the bottom 11 of the cumulative head 1, i.e., poly-
When energy head 1 carries out the heart sound conduct vibrations to being monitored people, bottom 11 and the resonance membrane 2 of cumulative head 1 can form a sky
Chamber.This mode is bonded compared to cumulative head 1 with the center position of resonance membrane 2 completely, is generated on the whole with resonance membrane 2
Vibrating effect it is relatively quite a lot of.
The cumulative portion 13 can also be in hollow out bar shape, to form the second cavity 14, and the second cavity 14 with
The first cavity 12 perforation that bottom 11 is formed, effect can be not good enough on conduction heart sound in this way for solid cumulative portion 13,
But gap is simultaneously little, and the cumulative head 1 made in this way can reduce production cost, and very slim and graceful, and is easier in film
On fix cumulative head 1, the echo formed by the first cavity 12 and the second cavity 14 comes together to reinforce resonance effect, to produce
Raw better using effect.In actual use, doctor can also use the longer time, because equipment can relatively more thus
Gently, using effect is more preferable, helps careful auscultation of doctor's reinforcement to noise in monitored popular feeling sound.
If the cumulative head 1 is big as the diameter in cumulative portion 13 using the diameter of bottom 11, and is to select solid material
Matter, then the effect on the monitored popular feeling sound of conduction of cumulative head 1 is preferable.Directly it is slightly larger than cumulative portion 13 with above-mentioned midsole portion 11
The mode of diameter, if cumulative head 1 is bonded completely with the center position of resonance membrane 2 at this time, film can effectively absorb low frequency
Signal, and vibration is generated, because of the gravity of cumulative head, although generally equally reducing what resonance membrane 2 can generate instead
Vibrating effect, but in effect gap and less.Another way, around the bottom 11 of the cumulative head 1 with resonance membrane 2
Center position is bonded completely, i.e., when cumulative head 1 carries out the heart sound conduct vibrations to being monitored people, the bottom of cumulative head 1
11 form a cavity as the mode for the diameter that resonance membrane 2 can directly be slightly larger than cumulative portion 13 with bottom 11 among the above.
But this mode is bonded compared to cumulative head 1 with the center position of resonance membrane 2 completely, is generated on the whole with resonance membrane 2
Vibrating effect it is relatively more preferable.
Above-mentioned several set-up modes can cause the vibration of resonance membrane 2 well, and gap is all little in effect.And it is current
Auscultation equipment in the prior art is all no cumulative head 1, and caused resonance effect is all directly to be bonded by resonance membrane 6
Human skin, directly monitors the mode for being monitored the heart sound of people, and the heart sound that this mode resonance membrane receives seems collection
Can be more, but actually there is no polymerization cardiechema signals, and noise is more, is easy, by external interference, to thus greatly reduce
Auscultation effect, and be difficult to by doctor recognize heart there may be the problem of.And the poly- sound that this programme passes through cumulative head 1 so that altogether
The resonance effect to shake a little is reinforced, and the effect of five to six times of collection heart sound is at least improved than existing auscultation equipment, preferably
Feed back the problem of monitored human heart is likely to occur.Although experienced expert physician could be used that common existing improve sets
It is standby, recognize inside monitored human heart there may be the problem of, but auscultation equipment used by this programme is because of cumulative head 1
In the presence of the sound of monitored popular feeling sound being expanded, even gengral practitioner also can accurately recognize the noise in existing heart sound, greatly
The big Accurate Diagnosis rate for having helped doctor, help have the monitored people of cardiac problems to be effectively treated in time.
The cumulative head 1 of above-mentioned all modes is all integrally made into, naturally it is also possible to is divided into several parts and is spliced into one
A entirety, and metal solid material is generally used, but it is not limited to metal solid material, metal solid material is only used, is total to
Spread speed of shaking is most fast, and consumption is relatively minimal, and most can accurately react actual conditions.If cumulative head 1 uses phase with film 2
Same material, it is also possible, because of the construction of cumulative head 1 so that it is bonded human skin in use with good crushing resistance
When, be not in deformation, be crushed, to influence to be monitored the conduction of popular feeling sound.In addition cumulative head 1 uses wood materials
Being can be with, and when conduction is monitored popular feeling sound, effect can slightly almost compared to metal material.Therefore, to cumulative head 1
Can be various solidity materials there is no too many limitation in material selection, using the special stream with preferably conduction heart sound
Body material is also feasible.
Preferably, the bottom 11 of the cumulative head 1 is preferred using circle, specific size diameter is generally 1cm to 3cm,
Distance of 12 highest point of the first cavity that the bottom 11 is formed apart from lowest point film 2 is 0.5mm to 3mm.The cumulative portion
13 height is 1cm to 3cm, and 14 internal diameter of the second cavity formed is 3mm to 6mm.The radian that first cavity 12 is formed
For the circular arc of radius 4cm.
The specific effect using after this programme, using the stethoscope of this programme under external monitoring device, same unit
In specification, under the same monitoring object of synchronization, identical signal its amplification effect difference monitored, and it is outer in connection
It sets under monitoring device, to the monitorings of data, it goes interference stronger, can preferably show differentiation frequency band signals.
