Description
Technical field
This utility model belongs to technical field of medical instruments, relates to the auscultation head, and particularly a kind of high sensitivity is used the auscultation head more.
Background technology
The auscultation head is the most frequently used diagnosis apparatus of doctor, since be applied to clinical since, profile and acoustic mode have continuous improvement, but that its basic structure changes is little.And how many traditional auscultation heads of always using till today exists the some shortcomings part; Such as because of simple in structure, volume is less, transaudient distortion, noise are big; Because function singleness is all incompatible with clinical examination, diagnosis and teaching, has all brought inconvenience to user and patient.Concrete weak point reason is following: 1, because the acoustical vibration cavity of traditional auscultation head is bowl-shape, this structure is less at the sound that diaphragm vibration back produces, and does not generally all reach the demand of enriching the clinical experience doctor, as easy as rolling off a logly causes mistaken diagnosis; 2, because traditional auscultation head vibration cavity is bowl-shape, this structure transaudient is will twice compression is transaudient again after the diaphragm vibration, can produce the indirect noise, so the distortion factor is bigger, also causes mistaken diagnosis easily; 3, because traditional auscultation greatest service can be single, when the doctor needs percussion, the consultation of doctors, teaching, then can't carry out,, influence the diagnosis and treatment quality so that prolong treatment time.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example, the Chinese patent document discloses a kind of auscultation head [number of patent application CN02158094.4, patent publication No. is CN1418603A]; It comprises a warehouse; Miniature charger, carbon fiber heater are housed in the storehouse, and miniature charger can become the voltage of 220V the safe voltage of 36V, and whole thermals source are supplied with carbon fiber heater by miniature charger in the storehouse; Carbon fiber heater is netted; Heat is evenly distributed in the storehouse, the continuable insulation of carbon fiber heater, thus supply with the warehouse net quantity of heat.Because be made up of double-layer structure at the bottom of the storehouse, the upper strata is a heat-conducting plate, lower floor is a flat thin magnet, and heat-conducting plate can make the sufficient draw heat of stethoscope head, and Magnet can make stethoscope head well fixing.Advantage of the present invention is: simple in structure, with low cost, effect significantly, make patient when inspection, reduce ice-cold sense of discomfort.
Though having eliminated stethoscope to a certain extent, technique scheme reduced the mistaken diagnosis probability in use, owing to the vibration cavity is that the bowl-shape defective that exists does not still obtain fine solution.On the other hand, it still keeping traditional auscultation greatest service can the aspect single cause using certain limitation is arranged, function is not well expanded.
Summary of the invention
The purpose of this utility model is to have the problems referred to above to existing technology, has proposed a kind of simple in structurely, is easy to assembling, sound clarity, can supply many people to use simultaneously, misdiagnosis rate is low, the high sensitivity of diverse in function is used the auscultation head more.
The purpose of this utility model can realize through following technical proposal: a kind of high sensitivity is used the auscultation head more; Tin body, diaphragm and the transaudient connection tube that comprise flat; The one side of described tin of body has the vibration cavity that caves inward; Another side is provided with above-mentioned transaudient connection tube, and an end of described transaudient connection tube is connected with the vibration cavity bottom, and described diaphragm is fixed on the vibration cavity through location structure; It is characterized in that; Be provided with in the described vibration cavity and can realize the multichannel transaudient resonance sound channel that resonates, at transaudient connection tube with listen the internal diameter that is provided with tapered vibration sound transmission aperture and vibration sound transmission aperture and the adjacent end of vibration cavity bulk phase between the body internal diameter greater than an adjacent end with transaudient connection tube, described transaudient connection tube has percussion portion with listening a bulk phase end even.
Diaphragm is close to and human body, and diaphragm is sounded along with the vibration of human body, and sound is imported in the transaudient connection tube by the vibration cavity, thereby is convenient to medical worker's auscultation.In this process, the same with traditional can, the sound that diaphragm sends is introduced into the vibration cavity: but in cavity in the past, compressed situation appears in sound easily, and it is fuzzy to cause sound originally to occur; And in this vibration cavity, owing to be provided with the resonance sound channel, this resonance sound channel undulate; Have crest and trough, meet the route of transmission of sound wave, be convenient to transmit; Avoid occurring the compressed situation of sound wave, can make the sound clarity of the intravital sound of vibration cavity, avoid unfavorable conditions such as distortion.The sound that the vibration cavity is received imports in the transaudient connection tube through the vibration sound transmission aperture again; It is conical that this vibration sound transmission aperture is; The bottom is communicated with the vibration cavity; The upper end then is connected with transaudient connection tube, and sound is convenient to collect in the bottom that diameter is bigger, and the upper end less through diameter converges to sound in the transaudient connection tube.In addition, percussion portion makes this auscultation head have the effect of percussion, the situation such as unhygienic that causes when avoiding the use of hands or other instrument percussion.
Use in the auscultation head in a kind of high sensitivity of the above, described resonance sound channel comprises some annular grooves that concentric circular distributes that are more, and described vibration sound transmission aperture is arranged on the circle centre position of above-mentioned annular groove.General circle centre position is the source point of sound, is set to accept the optimum position of sound with one heart.
Use in the auscultation head in a kind of high sensitivity of the above, described tin of body is provided with and is positioned at the peripheral annular positioning groove of resonance sound channel, in the described annular positioning groove O-ring seals is housed more.It is indispensable listening the sealing of body, realizes sealing through simple O-ring seals, not only be convenient to draw materials, and installing/dismounting is also convenient.
Use in the auscultation head in a kind of high sensitivity of the above, the other end of described transaudient connection tube has one or more arms more.When wherein being connected to a plurality of arm, can connect several Stethophone carriages, can realize many people auscultations simultaneously so easily, perhaps be used for the auscultation teaching.
Use in the auscultation head in a kind of high sensitivity of the above, the quantity of described arm is two more.
Compared with prior art, how this high sensitivity is with the advantage of auscultation head: 1, because the vibration cavity is provided with the resonance sound channel, it is transaudient that it has avoided traditional can cavity content to be prone to twice compression, causes situation such as audio distortions mistaken diagnosis.2, this utility model diverse in function can realize operations such as percussion, teaching in auscultation, has shortened the time of auscultation, has improved the diagnosis and treatment quality.3, stable work in work, long service life, simple and the for convenience detach and installation of hermetically-sealed construction.
