[0022] The preferred embodiment of the present invention is described in detail below with reference to the accompanying drawings. In addition, the embodiment described below does not unreasonably limit the content of the present invention described in the claims, and all the structures described in this embodiment are not essential as the solution of the present invention.

[0023] [Stethoscope]

[0024] like Figure 1 As shown, the stethoscope 1 comprises: a chest listening device 3 having a chest listening device 3 and a chest listening device 3 having a chest listening device 3 and a chest listening device 3; Figure 3 ) abutting parts 3a, 3b that pick up the sound of the examined part 2; a pair of earplugs 4, worn on the examinee's ears; a tube 5, connecting the chest listener 3 and the earplugs 4 to transmit the sound of the examined part 2 to the examinee; and an auscultation auxiliary device 6, installed on the chest listener 3.

[0025] The chest listening device 3 of this embodiment has two abutment parts 3a and 3b on the front and back sides. A diaphragm 30 is provided on one abutment part 3a and is used when picking up high-frequency sounds in the sound of the examination object part 2. An open bell is provided on the other abutment part 3b and is used when picking up low-frequency sounds in the sound of the examination object part 2.

[0026] The tube 5 of this embodiment includes a rubber tube 5a having one end connected to the chestpiece 3 and branched into two at the other end, and a pair of metal tubes 5b connecting the two branched rubber tubes 5a to the earplugs 4 , respectively.

[0027] [Auscultation auxiliary equipment]

[0028] like Figure 2 As shown, the auscultation auxiliary device 6 has a hollow sheet 7, which can be loaded and unloaded relative to the diaphragm 30, and the diaphragm 30 is arranged on the abutment portion 3a of the chest listening device 3. The hollow sheet 7 has: a first membrane portion 7a, which is installed on the diaphragm 30 in a loadable manner, and the diaphragm 30 is arranged on the abutment portion 3a of the chest listening device 3; a second membrane portion 7b, which abuts against the examination object part 2 and can deform along the concave and convex of the examination object part 2; and a hollow portion 7c, which forms a sealed state between the first membrane portion 7a and the second membrane portion 7b, and a transmission medium for transmitting sound is sealed in the hollow portion 7c.

[0029] According to such an auscultation auxiliary device 6, the second membrane portion 7b can be in close contact with the unevenness of the examination object part 2, and the sound picked up from the examination object part 2 can be transmitted to the diaphragm 30 arranged on the abutment portion 3a of the chest listening device 3 via the transmission medium sealed in the hollow portion 7c. As a result, the entire surface of the diaphragm 30 arranged on the abutment portion 3a of the chest listening device 3 can be vibrated, and it is also possible to prevent noise from invading from the gap between the chest listening device 3 and the examination object part 2, thereby improving the listening performance of the auscultation sound. In addition, when the examination object part 2 is a human body, by interposing the auscultation auxiliary device 6 between the chest listening device 3 and the human body, it is possible to prevent the uncomfortable coldness and hard touch of the metal chest listening device 3 from being transmitted to the human body. Moreover, by replacing the auscultation auxiliary device 6 for each patient, it is also possible to prevent the infection of diseases through the stethoscope 1.

[0030] In addition, the stethoscope can be more closely fitted to small newborns and thin subjects with little subcutaneous fat. In particular, in the case of extremely small subjects such as premature infants who have basically no flat examination surface, the size of the chest earpiece had to be miniaturized in the past, but by applying the present invention, the size of the chest earpiece can be kept the same.

[0031] like Figure 2 As shown in (a) in the figure, the planar shape of the hollow portion 7c is a circle similar to the diaphragm 30 provided on the contact portion 3a of the chest listening device 3, and preferably has a diameter substantially the same as that of the diaphragm 30 to which the auscultation auxiliary device 6 is attached. In this way, the sound picked up from the examination target part 2 can be efficiently transmitted to the chest listening device 3.

[0032] In addition, although not particularly shown, the planar shape of the hollow portion 7c is not limited to a circle, and may be an ellipse, a polygon, etc. The number of hollow portions 7c provided in one auscultation auxiliary device 6 is not limited to one, and a plurality of hollow portions 7c may be provided in one auscultation auxiliary device 6. Moreover, among the existing stethoscopes, there are stethoscopes having an elliptical chestpiece 3, and there are also stereo-type stethoscopes in which the chestpiece 3 is divided into two, and the shape and size of the diaphragm 30 disposed on such a chestpiece 3 can be appropriately changed.

[0033] As the transmission medium sealed in the hollow portion 7c, a gas is preferably used, but a liquid or a colloid having a fluidity that does not hinder the second film portion 7b from deforming along the unevenness of the examination target site 2 may be used.

[0034] When gas is used as the transmission medium, air or carbon dioxide is preferred. When the gas sealed in the hollow portion 7c is air, there is an advantage that the manufacture of the auscultation auxiliary device 6 becomes easy. When the gas sealed in the hollow portion 7c is carbon dioxide, it has the effect of amplifying the sound, and the listening performance of the auscultation sound can be further improved.

[0035] When liquid is used as the transmission medium, water or pure water which has no effect on the human body is preferably used. In this way, even if the first membrane portion 7a or the second membrane portion 7b is broken and the liquid in the hollow portion 7c leaks, the effect on the human body can be avoided.

[0036] The material constituting the first film portion 7a and the second film portion 7b is preferably a resin having high flexibility and excellent airtightness, for example, a resin film such as ethylene vinyl acetate copolymer, polyethylene terephthalate, polyurethane, polyethylene, polyparaxylene, polyester, or polypropylene can be used.

[0037] Preferably, the thickness of the first membrane portion 7a and the second membrane portion 7b is 10μm to 0.5mm. When the thickness of the first membrane portion 7a and the second membrane portion 7b does not satisfy the above range, the sealed content of the ruptured hollow portion 7c may flow out. If the thickness of the first membrane portion 7a and the second membrane portion 7b exceeds the above range, not only may the deformation along the concave and convex part of the examined object part 2 become difficult, but also the sound transmission may decrease. In addition, the first membrane portion 7a and the second membrane portion 7b may be transparent or colored, and may be printed with instructions for use, advertisements, patterns, etc. In the case where the person being examined is a child, characters facing children, etc. may also be printed on the second membrane portion 7b.

[0038] The auscultation auxiliary device 6 constructed in the above manner can be manufactured in the following manner, for example, by contacting the molten resin continuously fed in a film form from a flat die with the outer peripheral surface of a molding roller (not shown) provided with a predetermined number of suction cavities, to vacuum-form a protrusion that bulges into a hollow shape, thereby forming a cover film (second film portion 7b), and by thermally bonding a back film (first film portion 7a) to the opening side of the vacuum-formed protrusion, and sealing air in the protrusion to form a hollow sheet 7, and then cutting it for each auscultation auxiliary device 6. In this way, the auscultation auxiliary device 6 in which air as a transmission medium is sealed in the hollow portion 7c can be easily manufactured. For example, it can also be manufactured in the following manner, that is, the transmission medium is filled into the second film portion 7b pre-formed into a predetermined shape, and sealed through the first film portion 7a. When manufacturing the auscultation auxiliary device 6, so-called sterile cotton such as absorbent cotton containing a disinfectant can be sealed in the hollow portion 7c together with the transmission medium, and taken out after auscultation and sterilized to the affected part or the user's finger, stethoscope, etc.

[0039] The first film portion 7a is preferably configured to have an adhesive layer coated with an adhesive, and is attached to the diaphragm via the adhesive layer, and the diaphragm is disposed on the contact portion 3a of the chestpiece 3. In this way, not only is it easy to attach and detach the auscultation auxiliary device 6 to the chestpiece 3, but the auscultation auxiliary device 6 can also be provided in a state where it is attached to the release paper.

[0040] The adhesive preferably uses a weakly viscous adhesive material, which prevents the stethoscope auxiliary device 6 from falling off during use by a moderate adhesive force, and can easily peel off the stethoscope auxiliary device 6 from the chest listening device 3 after use. For example, it is preferred to have an adhesive force equal to that used in "Post-it (registered trademark)" manufactured by 3M. In addition, an adhesive that generates adhesive force when it contains water, such as that used in so-called water-based tapes, can also be used. In addition, the adhesive layer can also be provided by using a double-sided tape in which an adhesive is coated on both sides of a film substrate.

[0041] In addition, from a hygienic perspective, it is preferred that one or more stethoscope assisting devices 6 be cut one by one and supplied in a sterile packaged form by being attached to release paper. Alternatively, multiple stethoscope assisting devices 6 may be supplied in a roll-like form by being connected via perforations or the like.

[0042] The second membrane portion 7b preferably has an anti-slip property for suppressing sliding relative to the examination object part 2. For example, the second membrane portion 7b can be provided with an anti-slip property by forming the second membrane portion 7b using a membrane material that suppresses sliding, such as an elastomer, or by applying a sliding inhibitor that suppresses sliding, such as an epoxy resin, on the surface of the second membrane portion 7b that contacts the examination object part 2. As a result, sliding relative to the examination object part 2 is suppressed, so that the friction sound generated by sliding can be suppressed, and the listening performance of the stethoscope sound can be further improved.

[0043] In addition, the second film portion 7b is preferably subjected to an antibacterial treatment for inhibiting bacterial proliferation. For example, by coating or kneading an antibacterial agent for inhibiting bacterial proliferation (e.g., "ASK" manufactured by Nichisho Chemical Co., Ltd.) on the surface of the second film portion 7b in contact with the examination object part 2, infection of diseases caused by bacterial proliferation can be inhibited.

[0044] In addition, the transmission medium sealed in the hollow portion 7c is preferably sterilized before or after sealing in the hollow portion 7c.

[0045] [How to use]

[0046] like Figure 3 As shown in (a) in the figure, when auscultating the sound of the examination object part 2 with unevenness, it is difficult to ensure the close contact between the chest ear 3 and the examination object part 2, and the entire surface of the diaphragm 30 provided in the chest ear cannot be vibrated, or noise invades from the gap between the chest ear 3 and the examination object part 2, which may reduce the listening performance of the auscultation sound.

[0047] In this case, if Figure 3As shown in (b) in the figure, the auscultation auxiliary device 6 is installed on the diaphragm 30 provided on the abutment portion 3a of the chest listening device 3. Specifically, the diaphragm 30 provided on the abutment portion 3a of the chest listening device 3 is attached via the adhesive layer coated on the first membrane portion 7a of the auscultation auxiliary device 6. In this state, when the chest listening device 3 is placed on the examination object part 2, the second membrane portion 7b is in close contact with the concave and convex of the examination object part 2, and the sound picked up from the examination object part 2 is transmitted to the diaphragm 30 provided on the abutment portion 3a of the chest listening device 3 via the transmission medium sealed in the hollow portion 7c. In addition, in Figure 3 In the figure, the main part of the chest organ 3 is cut open to show the cross section of the main part.

[0048] If the auscultation auxiliary device 6 is used in this way, the entire surface of the diaphragm provided on the contact portion 3a of the chestpiece 3 can be vibrated, and noise can be prevented from invading the gap between the chestpiece 3 and the examination target part 2, thereby improving the listening performance of the auscultation sound. In addition, when the examination target part 2 is a human body, by interposing the auscultation auxiliary device 6 between the chestpiece 3 and the human body, the uncomfortable coldness and hard touch of the metal chestpiece 3 can be prevented from being transmitted to the human body. Moreover, by replacing the auscultation auxiliary device 6 for each patient, it is possible to prevent the infection of diseases through the stethoscope 1.

[0049] In addition, by using the auscultation auxiliary device 6 of this embodiment, the listening performance of the auscultation sound is improved, but too many extra sounds other than the sounds required for auscultation may be heard. For example, when auscultating heart sounds, it may be difficult to hear the heart sounds because they are mixed with other noises such as breathing sounds or lung movement sounds.

[0050] Therefore, if Figure 4 As shown, a stethoscope sound filter 8 for filtering and blocking low and medium-range sounds can be provided between the diaphragm 30 provided on the contact portion 3a of the chest listening device 3 and the hollow sheet 7 of the stethoscope auxiliary device 6. The stethoscope sound filter 8 is a vibration-damping sheet made of a rubber elastic body such as NBR (nitrile rubber) or ACM (acrylic rubber) with a thickness of about 0.5 to 2 mm. In addition, the stethoscope sound filter 8 can be composed of only one sheet, or can be composed of a plurality of thin sheets repeated.

[0051] In this way, by placing the auscultation sound filter 8 that functions as a vibration-damping sheet between the diaphragm 30 and the hollow sheet 7, it is possible to absorb sounds and vibrations below a specified frequency and convert them into heat energy. Therefore, the auscultation sound filter 8 filters out unnecessary noises in the sound range below 30 Hz, such as breathing sounds and lung movement sounds, so that it is easy to listen to heart sounds in the sound range of about 30 to 100 Hz. In particular, when you want to focus on auscultation of heart sounds during diagnosis, by placing the auscultation sound filter 8 between the diaphragm 30 and the hollow sheet 7, the noises in the sound range below 30 Hz are blocked. As a result, it is possible to auscultate heart sounds more accurately, and it is also possible to listen to subtle changes in heart sounds, thereby achieving high-precision auscultation of heart sounds.

[0052] That is, by arranging the auscultation sound filter 8 between the diaphragm 30 and the hollow sheet 7, it is possible to block low and medium-range noises in addition to achieving the functions and effects of the aforementioned auscultation auxiliary device 6. Therefore, for the examination target part 2 having various sizes or shapes, the hollow sheet 7 is deformed in a manner along the concave and convex surface of the examination target part 2. Therefore, in addition to suppressing the intrusion of noises from the gap between the chest listening device 3 and the examination target part 2, thereby improving the listening performance of the auscultation sound, the auscultation sound filter 8 can filter out the redundant noises in the low and medium ranges, thereby achieving high-precision auscultation of the heart sound.

[0053] In addition, it is preferred that one side 8a of the stethoscope sound filter 8 also has an adhesive layer, and the adhesive layer is coated with an adhesive that can be bonded to the hollow sheet 7. The adhesive constituting the adhesive layer is selected to use an adhesive material with weak viscosity, so as to prevent the stethoscope auxiliary device 6 from falling off during use through moderate adhesive force, and the stethoscope auxiliary device 6 can be easily peeled off from the chestpiece 3 after use. For example, it is preferred to have an adhesive force of the same degree as the adhesive used in "Post-it (registered trademark)" manufactured by 3M. In this way, the stethoscope sound filter 8 is provided with an adhesive layer, and the stethoscope sound filter 8 is easier to adhere to the adhesive than the hollow sheet 7 in terms of material. Therefore, the stethoscope auxiliary device 6 can be easily loaded and unloaded through the adhesive layer more reliably, and the stethoscope auxiliary device 6 can also be prevented from falling off.

[0054] In addition, in the above-mentioned auscultation auxiliary device 6 of the present embodiment, the transmission medium such as air is sealed in the hollow portion 7c of the hollow sheet 7, but the transmission medium may be sealed in the hollow portion 7c as necessary.

[0055] That is, Figure 5As shown in (a) of FIG. 1 , another embodiment of the auscultation auxiliary device 16 may be such that the second membrane portion 17b is configured to be freely expandable and contractible relative to the first membrane portion 17a as the base material of the hollow sheet 17, and a sealing tube 17d is provided on the second membrane portion 17b, and the sealing tube 17d seals a transmission medium composed of a gas such as air or a liquid such as water into the hollow portion 17c through an external pump or syringe, etc. In this way, by connecting the sealing tube 17d for sealing the transmission medium to the second membrane portion 17b, the capacity of the hollow portion 17c can be changed as needed.

[0056] In this embodiment, if Figure 5 As shown in (b) in the figure, during auscultation, if the transmission medium is sealed in the hollow part 17c and the transmission medium is filled into the hollow part 17c, the hollow sheet 17 expands and is configured along the shape of the examination target part 2. Therefore, the entire surface of the diaphragm provided on the abutment part 3a of the chest listening device 3 can be vibrated, and the noise can be prevented from invading from the gap between the chest listening device 3 and the examination target part 2, thereby improving the listening performance of the auscultation sound.

[0057] In addition, in this embodiment, the capacity of the hollow portion 17c can be changed by sealing the transmission medium in the hollow portion 17c when necessary, thereby realizing the miniaturization of the auscultation auxiliary device 16 during transportation and reducing the transportation cost. In addition, regarding the transmission medium injected into the hollow portion 17c, gas such as air or liquid such as water is injected. For example, when the lightness of the auscultation auxiliary device 16 is prioritized, gas is injected, and when the easier transmission of sound is prioritized, liquid is injected.

[0058] Furthermore, in the present embodiment, the auscultation auxiliary device 16 is configured to be attachable and detachable relative to the diaphragm provided on the chestpiece 3, and the auscultation auxiliary device capable of changing the volume of the hollow portion may be directly mounted on the contact portion 3a of the chestpiece 3 of the stethoscope 1. In addition, by providing the auscultation sound filter 8 between the diaphragm provided on the contact portion 3a of the chestpiece 3 of the stethoscope 1 and the auscultation auxiliary device 16, it is possible to block unnecessary noise in the low and middle ranges, and to perform auscultation of the heart sound with high accuracy.

[0059] Furthermore, although the auscultation sound hearing performance is improved by using the auscultation auxiliary devices 6 and 16 of the above-mentioned embodiments, the auscultation sound may be muffled. Therefore, an auscultation sound amplifier 9 for amplifying the auscultation sound may be provided between the diaphragm 30 and the hollow sheets 7 and 17 of the stethoscope 1.

[0060] like Figure 6As shown, the auscultation sound amplifying unit 9 includes an annular member 9a, a convex member 9b, and a plate-like member 9c. The annular member 9a is an annular member that contacts the outer edge of the diaphragm 30, and functions as a gasket for ensuring the height of the convex member 9b that contacts the diaphragm 30. The convex member 9b is configured such that a protrusion 9b1 that contacts the center of the diaphragm 30 is provided on a base 9b2, and the convex member 9b is provided on the inner side of the annular member 9a. The plate-like member 9c is a thin plate-like member provided between the base 9b2 of the convex member 9b and the hollow sheets 7 and 17, and has a function of transmitting vibration from the hollow sheet 7 while supporting the annular member 9a and the convex member 9b.

[0061] The annular member 9a and the plate-like member 9c and the base 9b2 of the convex member 9b and the plate-like member 9c are fixed by, for example, double-sided tape or adhesive. The annular member 9a, the convex member 9b and the plate-like member 9c constituting the auscultation sound amplifying unit 9 are made of resins such as epoxy resin, nylon resin, polymer resin, silicone resin, polyurethane, or metals such as stainless steel, similarly to the diaphragm 30.

[0062] By arranging such auscultatory sound amplifying part 9 between the diaphragm 30 and the hollow sheet 7, as shown in FIG. Figure 7 As shown, the annular member 9a abutting against the outer edge of the diaphragm 30 and the convex member 9b abutting against the center of the diaphragm 30 are supported by the plate member 9c abutting against the hollow sheet 7. Therefore, the sound waves from the examination target site 2 are transmitted to the plate member 9c via the hollow sheet 7, causing the plate member 9c to vibrate.

[0063] As a result, the plate-like member 9c swings, and the protrusions 9b1 of the convex member 9b intermittently abut against the surface of the diaphragm 30, generating sound waves from the diaphragm 30. Therefore, the displacement of the vibrating portion of the hollow sheet 7 is amplified by the plate-like member 9c, causing the diaphragm 30 to vibrate with a larger amplitude, thereby amplifying the auscultation sound.

[0064] That is, by providing the auscultation sound amplifier 9 between the diaphragm 30 and the hollow sheet 7, in addition to achieving the functions and effects of the aforementioned auscultation auxiliary device 6, the auscultation sound can also be amplified. Therefore, for the examination target part 2 having various sizes and shapes, the hollow sheet 7 is deformed in a manner along the concave and convex surface of the examination target part 2. Therefore, in addition to suppressing the invasion of noise from the gap between the chest listening device 3 and the examination target part 2 and improving the listening performance of the auscultation sound, the auscultation sound is amplified by the auscultation sound amplifier 9, so that the auscultation sound becomes not muffled, and high-precision auscultation of heart sounds or respiratory sounds can be performed.

[0065] As mentioned above, although the preferred embodiment of the present invention was shown and described, the present invention is not limited to the above-mentioned embodiment, and it is needless to say that various modifications can be made within the scope of the present invention.

[0066] Industrial Applicability

[0067] The embodiments of the present invention are applicable not only to medical stethoscopes for auscultating heart sounds, respiratory sounds, etc. of the human body, but also to industrial stethoscopes for auscultating abnormal mechanical sounds, etc.
