Abstract:
Upon using a stethoscope, there is a problem that it had been needed to interrupt work and mount the stethoscope using both hands, resulting in poor work efficiency. Also, when it is needed to repeatedly mount and unmount the stethoscope for such as a group examination, for example, it had been necessary to continuously carry out an operation of expanding ear tubes many times, which is complicated. Thus the present invention provides an attachment for a stethoscope comprising a mounting part which can be mounted to both of ear tubes, and a manipulating part for manipulating the mounting part, the manipulating part and the mounting part being connected through a rotatable fulcrum, so that the mounting part may be opened and closed by opening and closing operation of the manipulating part.

Description:
TECHNICAL FIELD 
     The present invention relates to an attachment for stethoscope to be attached to a stethoscope. 
     BACKGROUND ART 
     Conventionally, there has been provided a stethoscope which is used by doctors, nurses, etc., and comprises a sound collection unit for detecting the auscultation sounds and an ear tube, which is branched into a left-side tube portion and a right-side tube portion so as to be inserted into the left and right ears of a user, and the left-side tube portion and the right-side tube portion being connected by use of a connecting pipe, such as a rubber pipe. In such stethoscope, when the doctor or the like who is the user puts on the stethoscope, it is required such manipulation (expansion operation) that an external force is applied to the ear tube, (i.e., the left-side and right-side tube portions in a state of being close to each other with the elastic force of the ear tube itself), in the direction of expanding the interval between the left tube portion and the right tube portion. Therefore, for putting on the stethoscope, it is necessary for the doctors or the like as a user to use both hands. 
     Hereat, in the practical medical field, despite the need to perform various tasks, there is a problem in use of the stethoscope that it is required to stop the work once and to put on the stethoscope with both hands, leading to a poor working efficiency. Further, for example, in the case for a group medical examination as attachment and detachment of the stethoscope must be repeated, it is necessary and troublesome to carry out the foregoing expansion operation of the ear tube continuously many times. Thus, if it is realized to attach and detach the stethoscope only with one hand, while any necessary work being kept with other hand, further improvement of the work efficiency in the medical field can be expected. Reviewing from such a viewpoint as abovementioned, for example, it may be effective the TMJ stethoscope for screening as disclosed in Patent Document 1.

     SUMMARY OF INVENTION 
     Technical Problem 
     Here, the temporomandibular joint stethoscope for the screening described in Patent Document 1 mentioned above discloses that a spring loaded gripping means is provided onto the ear tube portion the examiner puts on, so that the examiner can put on the ear tube portion with one hand (see claim 4 of the Japanese unexamined patent application No. 2013-192919). But, the spring loaded gripping means of the invention of this prior art is not able to be retrofitted to the ear tube portion. Moreover, the spring loaded gripping means of the prior art invention is not envisaged to be retrofitted to existing stethoscopes and does not have any consideration for the purpose. Thus, it cannot be attached to existing stethoscopes such as those customarily used by a doctor etc., and it is not usable well. Stethoscopes are normally used being put on users&#39; (doctors, etc.) bodies, thereby different or separate stethoscopes may be used possibly depending upon users preferences, specific use, or the like. Hence, it is desired strongly provision of attachments which being able to be mounted to any existing or freely selected stethoscopes and usable without problems. 
     An expanding device for stethoscopes disclosed in the patent document 2 does, as apparently seen from  FIG. 1 , comprise a first member and a second member which are formed in a large round shape and protrudes upward than the branching portion of the connection tube described later. The members hit against or get in the way carrying the jaw of the user. To avoid this, the branching portion of the connection tube must be positioned as largely lowered downwards, thus, commercially available stethoscopes cannot be applied. 
     The present invention may, as mentioned foregoing, employ those of the ordinary stethoscopes selected by doctors (physicians, etc.) according to their own preferences and specific use. 
     In order to solve the above-mentioned problems, the present invention has an object to provide an attachment for stethoscope which may be attached to any freely selected stethoscopes, enabling the ear tube to be operated without the problems. 
     Solution to Problem 
     In view of the situation as above-mentioned, the present inventor&#39;s having conducted extensive studies have completed the present invention which: 
     an attachment  10  for a stethoscope which to be mounted to a stethoscope  1  comprising: 
     a sound collecting unit  2  for detecting the auscultation sounds, ear tube  3  branched into a left tube part  3   a  and a right tube part  3   b  so as to be inserted into the left and right ears of a user, and 
     a connecting pipe  4  which connects the sound collecting unit  2  and the left tube part  3   a  and the right tube part  3   b,    
     wherein an elastic force of the connecting pipe  4  urges the left tube part  3   a  and the right tube part  3   b  in a direction that the parts  3   a  and  3   b  become close to each other through the connecting pipe, so that there can be applied an external force in the opposite direction to the urging direction against the left tube part  3   a  and the right tube part  3   b , or one ends of the left tube part  3   a  and the right tube part  3   b  covered with ends of the connecting pipe  4  at the side of the ear tube  3  to provide an expansion state in which the left tube part  3   a  and the right tube part  3   b  are allowed to elastically deform and the interval of the left tube part  3   a  and the right tube part  3   b  expands,
 
characterized in that the attachment  10  for stethoscope  1  comprises: a mounting part  20  to be mounted onto the ear tube  3  and a manipulating part  22  for manipulating the mounting part  20 , the manipulating part  22  and the mounting part  20  are connected through a rotatable hinge  18 , so that the mounting part  20  may be opened and closed by opening and closing operation of the manipulating part  22 ,
 
and upon the attachment&#39;s being fit onto the stethoscope the hinge is positioned outside a region surrounded by the left tube part  3   a  and the right tube part  3   b , and the connecting pipe  4 .
 
     The attachment for stethoscope of the present invention enables that the mounting parts of the left and the right manipulation parts are each freely attached to or detached from the left and the right tube parts, respectively. Thus, the attachment for stethoscope of the present invention may be mounted for use to any stethoscopes freely selected by doctors, etc., with their preferences. And the attachment for stethoscope may be operated merely for causing the manipulating parts of the left and the right manipulation parts to approach with each other, so that the interval between the left and the right tube parts is expanded interlocking with the movement of the mounting part of the left manipulation part and that of the right manipulation part. By this, according to use of the attachment for stethoscope of the present invention, doctors, etc., are enabled to expand the interval between the ear tubes with their single hand operation and fit the ear tubes to ears. Hence, use of the attachment for stethoscope of the present invention can notably improve work efficiency of the doctors, etc. 
     Furthermore, in the attachment for stethoscope of the present invention, any one or both of the mounting part(s) of the left manipulation part and the right manipulation part may be, preferably, attached in a manner of being capable of sliding along the left tube part or the right tube part. 
     With the structure as above-mentioned, it is realized that upon the expansion operation, the mounting part may be caused to slide along the left or the right tube part, whereby, a load required for the expansion of the interval between the left and the right tube parts of the ear tube can be lowered. Thus, according to the present invention, there has been provided such attachment for stethoscope that the expansion operation for bringing the ear tube into the state of interval expansion can be carried out more lightly. 
     The above-mentioned stethoscope attachment of the present invention may be so structured that one or both of the mounting parts of the left manipulation part and the right manipulation part is/are mounted by use of amounting member fit winding outer peripheries of the mounting part together with the left or the right tube part. 
     With this structure, there has been provided such stethoscope attachment that the left tube part and the right tube part are ensured to be brought into the expansion state interlocking with the expansion operation by the left or right manipulation part. 
     The above-mentioned attachment for stethoscope of the present invention may be so structured that the attachment comprises an annular member for mounting one or both of the mounting parts of the left and the right manipulation parts to the left tube part or the right tube part, the mounting part is provided with an insertion part through which the annular member is able to be inserted through, so that the annular member inserted through the insertion part may be fit and wound on the left and the right tube parts, whereby mounting one or both of the mounting parts of the left and the right manipulation parts to the left tube part or the right tube part. 
     The hinge referred to in the present invention is a part where any members are connected in a manner of being able to rotate. The hinge should not be limited in shape and structure to any ones particularly. It may employ a hinge of such structure that members intersecting each other have a through bore through which a shaft member is merely inserted. 
     A big point of the present invention is that the hinge section, when the attachment is mounted to the stethoscope, is positioned outside the region surrounded by the left tube part  3   a , the right tube part  3   b  and the connecting pipe  4 . In other words, when the manipulating part is manipulated to narrow the interval between the manipulation part sections, the hinge part is moved upwards, and the hinge part even at this fresh position is positioned outside that region. 
     By this feature, the hinge part does not strike jaw and neck of users and not hinder them. 
     A stopper to prevent more than a predetermined extent of narrowing of the interval between the left and the right manipulation parts may be provided at the hinge part of the present invention. In detail, the left and the right manipulation parts in the stethoscope are in the state of being in proximity to each other due to an elastic force of the stethoscope itself. In case that the left and the right manipulation parts approach each other more than required, the left and the right manipulation parts get caught and troublesomely when in expansion operation. Thus, the hinge may be provided with a stopper for retaining and stopping the hinge in the midst of rotation so as to prevent lowering of interval of the manipulation parts more than required (a level of proximity more than that the ear tubes precisely fit into users ears). 
     When structured as the above-mentioned feature, the left manipulation part and the right manipulation part are enabled to be more surely mounted to the left tube part and the right tube part of the ear tube. By this, it is enabled that the interval between the left tube part and the right tube part is expanded surely interlocking with the movement of the left manipulation part and the right manipulation part in the expansion operation. Hence, according to the present invention, the left manipulation part and the right manipulation part are enabled to be more surely mounted to the left tube part and the right tube part of the ear tube, and also, certainty of the ear tube&#39;s movement of expansion in the expansion operation can be facilitated. 
     Advantageous Effects of Invention 
     According to the present invention, it is provided an attachment for stethoscope which may be mounted to any desired stethoscope to be able to manipulate ear tubes without any problems.

     DESCRIPTION OF EMBODIMENTS 
     First Embodiment 
     Hereinafter, explanation will be given regarding the attachment  10  for stethoscope according to the first embodiment of the present invention. In the following description, prior to the explanation of the stethoscope attachment  10  of this embodiment, a schematic configuration of a stethoscope  1  to which the invention is attached will be first explained. In the following description, unless otherwise specified, explanation will be given using positional correlation of the left and right and front and back sides with the state of the stethoscope  1  as arranged and shown in  FIG. 1  being taken as a reference. 
     (A Schematic Configuration of Stethoscope  1 ) 
     As shown in  FIG. 1 , the stethoscope  1  has a sound collecting unit  2 , an ear tube  3 , and a connecting pipe  4 . The sound collecting unit  2  is a part provided for detecting the auscultation sound by contacting with a target of sound collection such as a human body. 
     Ear tube  3  comprises a tubular body made of a metal tube or the like and is shaped as being curved to be capable of being inserted into left and right ears of a user such as a doctor. The ear tube  3  is branched into left and right tube parts  3   a  and  3   b  and mounts ear pieces  3   c  at the utmost ends which to be inserted into user&#39;s ears. The ear tube  3  is urged, by the elastic force of itself, into the direction in which the left and the right tube parts  3   a  and  3   b  become close to each other (arrow F direction in  FIG. 1 ). By applying an external force to the ear tube  3  in the opposite direction (the arrow A in  FIG. 1 ) to the foregoing urging direction, the ear tube  3  can be brought into the state that the interval between the left tube part  3   a  and the right tube part  3   b  is expanded (the expansion state). Users of the stethoscope  1  may have to only cause the ear tube  3  to be in the expansion state, that is, merely expanding the interval of the ear tube  3  widely in comparison with the interval between their both ears, so that the ear pieces  3   c  can be inserted into users both ears and put on. 
     The connecting pipe  4  is a pipe to connect the sound collecting unit  2  and the ear tube  3 . The connecting pipe  4  is formed with a pipe having high bendability made of a rubber pipe or a plastic pipe such as vinyl chloride. The connecting pipe  4 , at the section extending between the sound collecting unit  2  and the start part of branching into the left tube  3   a  and right tube  3   b  of the ear tube  3 , may be properly formed with: a single pipe, or, a single pipe having an inside partition wall; or, two pipes. Moreover, the connecting pipe  4  at the end at the side of the ear tube  3  partially covers the part of the left tube  3   a  and the right tube  3   b  (forming the ear tube  3 ) at their base ends (opposite to the side of ear piece  3   c ). 
     (Regarding Attachment  10  for Stethoscope) 
     As shown in  FIG. 1 , the attachment  10  for stethoscope is an attachment to be mounted to the above-mentioned stethoscope  1  to enable the operation for bringing the ear tube  3  into the expansion state. As seen in  FIGS. 1 and 2 , the stethoscope attachment  10  comprises a pair of manipulation units  12  (each also called hereunder when required a left manipulation part  14  and a right manipulation part  16 ) and a hinge  18 . 
     The manipulation unit  12  (left manipulation part  14  and right manipulation part  16 ) is so structured as having a mounting part  20  at one end and a manipulating part  22  at the other end. The manipulation unit  12  is formed by working a wire material (such as wire) into a shape of bending. The left and the right manipulation parts  14  and  16  are in a shape of substantially symmetric with each other. 
     The left and the right manipulation parts  14  and  16  can be each mounted (at the mounting part  20 ) to and detached from the left tube  3   a  and the right tube  3   b , respectively. In detail, the mounting part  20  is in a shape of a hook bending along the outer peripheries of the left tube  3   a  and the right tube  3   b . The mounting part  20  can be mounted to the left tube  3   a  and the right tube  3   b  in a manner of catching the left tube  3   a  and the right tube  3   b  in the direction extending outwardly from the region X defined (inside) by the left tube  3   a  and right tube  3   b . In the present embodiment, the mounting part  20  of the left manipulation part  14  and the right manipulation part  16  are mounted to the sections of the left tube  3   a  and right tube  3   b  at their base ends covered with the connecting pipe  4  made of rubber or the like. Thus, the mounting parts  20  are mounted to the connecting pipe  4  in a manner of not easily falling thanks to a frictional force occurring between the connecting pipe  4  and the mounting parts  20 . 
     The manipulating part  22  is formed on the manipulation unit  12  at the side opposite to the mounting part  20 . The manipulating part  22  is a part to be caught by users fingers upon manipulation of the attachment  10  for stethoscope. In detail, one of the manipulating part  22  of the left and the right manipulation part  14  and  16  is caught, for example, by thumb or the like of users hands, and the other manipulating part  22  caught by forefinger or the like of users hands. And users holding movement with fingers (as shown by the arrow B in  FIG. 1 ) to cause the fingers (holding the manipulating parts  22  of the left and the right manipulation parts  14 ,  16 ) to approach each other enables performance of the operation for moving the left and the right manipulation parts  14 ,  16  in the direction shown by the arrow A in  FIG. 1 . 
     The hinge  18  is provided at an intermediate position between the mounting part  20  of the left and the right manipulation parts  14 ,  16  and the manipulating part  22  and connects the left and the right manipulation parts  14  and  16  in a manner of enabling the same to be operated opened and closed. In this embodiment, the hinge  18  is formed in such manner that a fulcrum shaft  24  made from a combination of bolt and nut or the like is inserted through a hole-like part provided by looping a wire material which forms the left manipulation part  14  and the right manipulation part  16 . Furthermore, in this embodiment, the hinge  18  is provided at both sides, namely, the front side and the back side of the stethoscope attachment in the state of being mounted to the stethoscope  1 . 
     The stethoscope attachment  10  functions such that the manipulating parts  22  are held by users with their fingers (as shown by the arrow B in  FIG. 1 ) to cause the manipulating parts  22  of the left and the right manipulation parts  14 ,  16  to approach each other, thereby enabling expansion of the interval between the mounting parts  20  of the left and the right manipulation parts  14 ,  16  shown by the arrow A in  FIG. 1 . By this, such manipulation (expansion operation) is enabled that an external force is applied to the left tube part  3   a  and the right tube part  3   b  to expand the interval between the tube parts  3   a ,  3   b . Hence, the stethoscope attachment  10  may be used, by users such as doctors or the like, to enable them to expand the interval of the ear tube  3  with manipulation using a single hand and put the ear tube to the ear. Moreover, when users stop holding the manipulating part  22  with their fingers, the ear tube  3  returns to its original state thanks to the own elastic force of the ear tube  3 . Thus, user applies the ear tube  3  (whose interval has been expanded in the direction of the arrow A with the expansion operation) to ears, thereafter, merely stops holding the manipulating part  22  with their fingers, so that putting on the stethoscope  1  completes. Also, when user wants to take off the stethoscope  1 , mere manipulation of holding the manipulating parts  22  with their fingers to expand the interval of the ear tube  3  is sufficient for taking off the stethoscope  1 . 
     As above-mentioned, the attachment  10  for stethoscope enables readily putting on and taking off the stethoscope  1  by operating the manipulating part  22  with a single hand. Hence, by use of the attachment  10  for stethoscope, working efficiency of doctors, etc., can be improved remarkably. 
     Furthermore, the above-mentioned stethoscope attachment  10  may be attached for use to any stethoscopes  1  freely selected by the doctors or the like. Thus, according to the stethoscope attachment  10 , with respect to various types of stethoscope  1  selected by the doctors or the like on the basis of their preference, use, or the like, attaching and detaching of the stethoscope attachment  10  can be carried out with a single hand. 
     Second Embodiment 
     Hereunder, an attachment  100  for stethoscope according to the second embodiment of the present invention will be explained with referring to an example of mounting to the foregoing stethoscope  1 . A structure in the attachment  100  common to the stethoscope attachment  10  of the above-mentioned first embodiment is designated by reference numbers prepared with the original reference numbers in the first embodiment plus  100 . And detailed explanation of such structure(s) will be omitted. 
     A stethoscope attachment  100  is an attachment to be mounted to a stethoscope  1  similarly to the foregoing stethoscope attachment  10  for enabling the operation for bringing the ear tube  3  into the state of expansion. As shown in  FIG. 3 , the stethoscope attachment  100  comprises a pair of manipulation unit  112  (each also called hereunder when required a left manipulation part  114  and a right manipulation part  116 ) and a hinge  118 . And the stethoscope attachment  100  is different in structure from the above-mentioned stethoscope attachment  10  in that it is provided with a mounting member  130  for mounting the left and the right manipulation part  114 ,  116  to the left and the right tube part  3   a ,  3   b.    
     The manipulation unit  112  (left manipulation part  114  and right manipulation part  116 ) is so structured as having amounting part  120  at one end and a manipulating part  122  at the other end. The manipulation unit  112  is formed by working a wire material (such as wire). The left and the right manipulation parts  114  and  116  are in a shape of substantially symmetric with each other. 
     The manipulation unit  112  is different, at the structure of the manipulating part  120 , from the mounting part  20  forming the stethoscope attachment  10  of the foregoing first embodiment. In detail, the mounting part  120  is mounted along the left tube part  3   a  or the right tube part  3   b  similarly to the mounting part  20  but is different therefrom in the specific mounting structure. Specifically, the mounting part  20  is in a shape of being bent to be able to be mounted to the left or the right tube part  3   a ,  3   b  in a manner of being caught from the inside of the region X. Meanwhile, the mounting part  120  is different from the mounting part  20  in such structure that it is in a shape of extending straightly and employs a mounting member  130  for mounting the mounting part  120  to the left or the right tube part  3   a ,  3   b.    
     The mounting part  120  in the state of being mounted to the stethoscope  1  has such length that it extends to reach a position more away toward the utmost end from a part of the left tube part  3   a  or the right tube part  3   b  covered with the connecting pipe  4 . The mounting part  120  is mounted to the left or the right tube part  3   a  or  3   b  by means of amounting member  130  at a position more away toward the utmost end from a region of the left tube part  3   a  or the right tube part  3   b  covered with the connecting pipe  4 . The mounting member  130  may employ a wire or the like in an annular shape, an annular member such as a clamping band, or a cylindrical member and be mounted as winding the outer peripheries of both of the left or the right tube part  3   a  or  3   b  and the mounting part  120  arranged along the left or the right tube part  3   a  or  3   b.    
     The manipulating part  122  of the manipulation unit  112  is though different in shape from the manipulating part  22  forming the stethoscope attachment  10  in the foregoing first embodiment, it shows the same function. That is, the manipulating part  122  is provided on the manipulation unit  112  at the opposite position to the mounting part  120 , and it is so structured that it can be hooked by user&#39;s fingers upon manipulation. 
     The hinge  118  is provided at an intermediate position between the mounting part  120  forming the left and the right manipulation unit  114 ,  116  and the manipulating part  122 . And the hinge  118  connects the left and the right manipulation parts  114  and  116  in a manner of enabling the same to be operated opened and closed. The hinge  118  is structured similarly to the foregoing hinge  18  in such manner that a fulcrum shaft  124  made from a combination of bolt and nut or the like is inserted through a hole-like part provided by looping a wire material which forms the left manipulation part  114  and the right manipulation part  116 . 
     The stethoscope attachment  100  does, similarly to the foregoing stethoscope attachment  10 , function such that the manipulating parts  122  are held by users with their fingers to cause the interval between the manipulating parts  122  to narrow, thereby enabling expansion of the interval between the manipulating parts  120  of the left and the right manipulation parts  114 ,  116  (expansion operation). By carrying out the expansion operation, it is enabled to expand the interval between the left and the right tube parts  3   a ,  3   b . Besides, by making lower the holding force holding (with fingers) the manipulating parts  122 , the interval between the left tube part  3   a  and the right tube part  3   b  can be returned to the state not subjected to an external force. Thus, the stethoscope attachment  100  also may be used to realize that users such as doctors or the like can attach and detach the stethoscope  1  with a single hand. Also, the above-mentioned stethoscope attachment  100  may be attached for use to any stethoscope  1  freely selected by the doctors or the like. 
     Furthermore, in the stethoscope attachment  100 , the mounting part  120  is mounted to the left tube  3   a  or the right tube part  3   b  by use of the mounting part  130  at a position away toward the utmost end from the region of the left tube part  3   a  or the right tube part  3   b  covered by the connecting pipe  4 . Thus the mounting part  120  contacts with the left or the right tube part  3   a ,  3   b  at their sections being exposed, so that the mounting part  120  is subjected to low sliding resistance at the mounting position in comparison with the foregoing stethoscope attachment  10 . Thus the mounting part  120  is able to readily slide along the left or the right tube part  3   a ,  3   b . By this structure, load required for holding (with fingers) the manipulating part  122  upon carrying out the expansion operation can be lowered. Hence, according to the stethoscope attachment  100 , the expansion operation bringing the ear tube  3  into the expansion state can be carried out more lightly. 
       FIG. 5  is a front view showing further other example of the stethoscope attachment  201  according to the present invention in the state of being not assembled. In this example, the whole of the attachment  201  is made of plastic. The left manipulation part  202  and the left manipulating part  203  are formed in a manner of being unified and having a through bore part  206  centrally. Also, the right manipulation part  204  and the left manipulating part  205  are formed in a manner of being unified and having a through bore part  206  centrally. A shaft member is provided to be inserted through the through bore of the through bore part  206  in a manner of enabling rotation. 
     The end  207  of the manipulation part  202 ,  204  is smaller in width a little in this example (such feature though not indispensable).  FIG. 6  shows the state of the through bore parts  206  assembled, with a shaft member being inserted, to be rotatable. Besides, fixed at the end part  207  of the manipulation part is a grasping means  208  which is to be fit and fixed to the ear tube  3  of the stethoscope. The ear tube  3  may be fit in a groove  209  formed on the grasping means  208 . Otherwise, the connecting pipe  4  may be fit in the groove  209  depending upon the size of the groove  209 . 
     The grasping means  208  may be subjected, at the groove  209 , to anti-slipping working, such as making concave and convex, applying rubber, or the like. Furthermore, an anti-slipping means separate from the grasping means  208  may be fixed to the ear tube  3 . And the anti-slipping means may be provided with a screw or the like to be tightened. 
       FIG. 7  is a perspective view of the grasping means  208  shown in  FIG. 6 . The grasping means  208  has a recess  210  (into which the end part  207  is inserted) and the groove  209  at the opposite side. The grasping means  208  enables readily fixing to the ear tube. 
     Hereby the specific embodiments of the present invention have been explained with referring to the attached drawings. But, it will be appreciated that concrete structures should not be limited to those mentioned embodiments. Scope of the present invention shall be expressed with the patent claims but not with the foregoing explanation of the embodiments. And the scope of the present invention shall cover all modification within equivalent meanings and extent to the patent claims. For example, in the second embodiment, the example is shown that the mounting part  120  in an almost straightly extending wire-like or bar-like shape is arranged along the left or the right tube part  3   a  or  3   b  and a mounting member  130  is mounted as winding around the outer peripheries of the mounting part  120  and the left or the right tube part  3   a  or  3   b . The structure for mounting the mounting part  120  is not limited to this. Specifically, as shown in  FIG. 4 , the mounting part  120  may be provided with an insertion bore  120   a  and an annular member  140  in an annular shape is prepared similarly to the mounting member  130 . And the annular member  140  is inserted through the insertion bore  120   a  and is mounted as winding around the left or the right tube part  3   a  or  3   b . By this, the mounting part  120  is enabled to be mounted more securely to the left or the right tube part  3   a  or  3   b.    
     Also, in the manipulating part  22  of the first embodiment and that  122  of the second embodiment, a cover made of a flexible material such as rubber may be fit on the surface. By this, the manipulating part, upon manipulation of the stethoscope attachment, can be prevented from catching fingers of users hands, whereby providing a stethoscope attachment readily operated by users. 
     INDUSTRIAL APPLICABILITY
