- the auscultation sound filter 8 is provided with the adhesive layer in which the adhesive is more easily adhered to the material than the hollow sheet 7, the auscultation assisting tool 6 can be easily attached and detached through the adhesive layer more reliably. Therefore, the dropout of the auscultation aid 6 is also suppressed.
- a 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 when necessary. Good.
- the second film portion 17b is flexibly configured with respect to the first film portion 17a which is the base material of the hollow sheet 17.
- the second film portion 17b may be provided with an encapsulation tube 17d in which a transmission medium composed of a gas such as air or a liquid such as water is enclosed in the hollow portion 17c by an external pump, a syringe or the like.
- the hollow sheet 17 when the hollow portion 17c is filled with the transmission medium during auscultation and the hollow portion 17c is filled with the transmission medium, the hollow sheet 17 is expanded. It will be arranged so as to follow the shape of the examination target portion 2. Therefore, the entire surface of the diaphragm disposed on the contact portion 3a of the chest piece 3 can be vibrated, and noise may enter through the gap between the chest piece 3 and the examination target portion 2. Since it can be prevented, the listening performance of the auscultation sound can be improved.
- the auscultation assisting tool 16 during transportation can be miniaturized and the transportation cost can be reduced. become.
- a gas such as air or a liquid such as water is injected into the transmission medium to be injected into the hollow portion 17c.
- the gas is injected to make a sound. If priority is given to facilitating transmission, a liquid is injected.
- the auscultation assisting tool 16 is detachably attached to the diaphragm arranged in the chest piece 3, but the auscultation assisting tool that makes it possible to change the capacity of the hollow portion is the chest of the stethoscope 1. It may be configured to be directly attached to the contact portion 3a of the piece 3. Further, by providing the above-mentioned auscultation sound filter 8 between the diaphragm arranged at the auscultation portion 3a of the chest piece 3 of the stethoscope 1 and the auscultation aid 16, the extra noise in the low and middle range is blocked. Then, auscultation with high accuracy of heart sound may be possible.
- the auscultation sound listening performance is improved, but the auscultation sound may be muffled. Therefore, the auscultation sound amplification unit 9 for amplifying the auscultation sound may be provided between the diaphragm 30 of the stethoscope 1 and the hollow sheets 7 and 17.
- the auscultation sound amplification unit 9 includes an annular member 9a, a convex member 9b, and a plate-shaped member 9c.
- the annular member 9a is a ring-shaped member that abuts on the outer edge of the diaphragm 30, and functions as a spacer for ensuring the height of the convex member 9b that abuts on the diaphragm 30.
- the convex member 9b is configured by providing a protrusion 9b1 that contacts the central portion of the diaphragm 30 at the base portion 9b2, and is provided inside the annular member 9a.
- the plate-shaped member 9c is a thin plate-shaped member provided between the base portion 9b2 of the protrusion member 9b and the hollow sheets 7 and 17, and is formed from the hollow sheet 7 while supporting the annular member 9a and the convex member 9b. It has the function of transmitting the vibration of.
- the space between the annular member 9a and the plate-shaped member 9c and the space between the base portion 9b2 of the convex member 9b and the plate-shaped member 9c are fixed, for example, with double-sided tape or an adhesive.
- the annular member 9a, the convex member 9b, and the plate-shaped member 9c constituting the hearing sound amplification unit 9 are made of, for example, a resin such as epoxy resin, nylon resin, polymer resin, silicone, urethane, or stainless steel. It is composed of metal such as steel.
- the plate-shaped member 9c swings and the protrusion 9b1 of the convex member 9b intermittently contacts the surface of the diaphragm 30, and a sound wave is generated from the diaphragm 30. Therefore, after the displacement amount of the vibrating portion of the hollow sheet 7 is amplified by the plate-shaped member 9c, the diaphragm 30 is vibrated with a larger amplitude, so that the auscultation sound can be amplified.
- the auscultation sound amplification unit 9 between the diaphragm 30 and the hollow sheet 7, it becomes possible to amplify the auscultation sound while exerting the actions and effects of the auscultation aid 6 described above. For this reason, the hollow sheet 7 is deformed along the uneven surface of the examination target portion 2 with respect to the examination target portion 2 having various sizes and shapes, so that the gap between the chest piece 3 and the examination target portion 2 After suppressing the intrusion of noise and improving the listening performance of the auscultation sound, the auscultation sound is amplified by the auscultation sound amplification unit 9, so that the auscultation sound is not muffled, and the auscultation sound and breath sounds are not muffled. You will be able to perform highly accurate auscultation.
- Each embodiment of the present invention can be applied not only to a medical stethoscope for auscultating the heart sounds and breath sounds of the human body, but also to an industrial stethoscope for auscultating abnormal sounds of machines.

Abstract
Description
図1に示すように、聴診器1は、人体などの診察対象部2(図3参照)に当接される当接部3a,3bを有し、診察対象部2の音を拾うチェストピース3と、診察者の耳に装着される一対のイヤーチップ4と、チェストピース3とイヤーチップ4とを連通して診察対象部2の音を診察者に伝達するチューブ5と、チェストピース3に装着される聴診補助具6とを備える。
図2に示すように、聴診補助具6は、チェストピース3の当接部3aに配設されたダイヤフラム30に着脱可能に装着される中空シート7を備える。中空シート7は、チェストピース3の当接部3aに配設されたダイヤフラム30に着脱可能に装着される第1フィルム部7aと、診察対象部2に当接され、診察対象部2の凹凸に沿って変形可能な第2フィルム部7bと、第1フィルム部7aと第2フィルム部7bとの間に密閉状に形成される中空部7cとを備えており、中空部7cには、音を伝達する伝達媒体が封入されている。
る溶融樹脂を接触させて、中空状に膨出する突起を真空成形することによってキャップフィルム(第2フィルム部7b)を形成しつつ、真空成形された突起の開口側にバックフィルム(第1フィルム部7a)を熱融着し、当該突起内に空気を封入して中空シート7を形成した後に、聴診補助具6毎に切り離すことにより製造することができる。このようにすることで、中空部7cに伝達媒体として空気が封入された聴診補助具6を容易に製造することができるが、例えば、予め所定形状に成形された第2フィルム部7bに伝達媒体を充填しつつ、第1フィルム部7aで封入するようにして製造することもできる。聴診補助具6を製造する際に、伝達媒体とともに、脱脂綿などに消毒薬を含ませた、いわゆる消毒綿を中空部7cに封入しておき、聴診後に取り出して患部や、使用者の手指、聴診器などを消毒できるようにすることも可能である。
また、中空部7cに封入する伝達媒体についても、中空部7cに封入する前に又は封入した後に滅菌処理を施すのが好ましい。
図3の(a)に示すように、凹凸のある診察対象部2の音を聴診する場合、チェストピース3と診察対象部2との密着性を確保することが困難であり、チェストピースに配設されたダイヤフラム30の面全体を振動させられなかったり、チェストピース3と診察対象部2との間の隙間から雑音が侵入したりすることに起因し、聴診音の聞き取り性能が低下
