腔内と外部の気圧を等しく５て鼓膜の変形と中耳内貯溜
液の耳管よりの排出を容易にし、難聴を予防することに
ある。これには次のような欠点がある
１） 鼓膜より中耳内に挿入されたチューブは中腔にな
っているため、外部より中耳内に細菌や汚れた空気ある
いは不潔な水が侵入して炎症をすぐに起こしてしまう。(Prior Art) Currently, a hollow ventilation tube (hereinafter referred to as tube) is used as a treatment for otitis media with effusion. This involves inserting a tube into the middle ear through the eardrum, which equalizes the air pressure inside and outside the middle ear cavity, making it easier to deform the eardrum and drain fluid stored in the middle ear from the Eustachian tube, thereby preventing hearing loss. It is in. This has the following drawbacks: 1) The tube inserted into the middle ear from the eardrum has a hollow cavity, so bacteria, dirty air, or unclean water can enter the middle ear from the outside. It causes inflammation quickly.
２）チューブ挿入中は入浴時に中耳内に水が入らないよ
う注意しなければならない、特に洗髪時には注意が必要
である
３） 水泳は十分な耳栓をしない限り不可能である４）
チューブを挿入する場合医師は十分の経験と熟練を要す
る。しかも外耳道が細い患者では挿入不可能の場合もあ
る。2) While the tube is inserted, you must be careful not to let water get into your middle ear when bathing, especially when washing your hair. 3) Swimming is not possible unless you wear enough earplugs. 4)
Physicians need sufficient experience and skill when inserting tubes. Moreover, it may not be possible to insert it in patients with narrow ear canals.
５）チューブを挿入する際鼓膜に大きな切開を必要とし
９時には出血が多量になり挿入が不可能になることもあ
る。5) Inserting the tube requires a large incision in the eardrum, and by the time the tube is inserted, there may be so much bleeding that it may become impossible to insert it.
６） チューブの中腔内に血液または膿が詰まりペンナ
レーションの役目をしなくなる。6) The lumen of the tube becomes clogged with blood or pus, making it unable to function as a pen narration.
７）チューブ挿入後数日は耳閉感および違和感がある。7) There is a feeling of fullness and discomfort in the ear for several days after the tube is inserted.
（発明が解決しようとしている課題）
現在使用中のチューブを鼓膜に挿入された患者は次のよ
うな問題がある。(Problems to be Solved by the Invention) Patients who have the currently used tube inserted into their eardrum have the following problems.
■）入浴および洗髪時に耳に水を入れない。■) Do not let water enter your ears when bathing or washing your hair.
２） 水泳はしない。2) I don't go swimming.
３） 強く鼻をかめない。3) Don't blow your nose too hard.
４）挿入後の違和感。4) Uncomfortable feeling after insertion.
５） 今まで挿入不可能であった外耳道狭窄患者。5) Patients with external auditory canal stenosis for whom insertion was not possible until now.
浸出性中耳炎患者の８０％は小児である。上記の問題点
（１−４）は特に小児にとってはストレスとる。80% of patients with otitis media with effusion are children. The above problems (1-4) are especially stressful for children.

。In order to solve these problems, the present invention uses a water-repellent synthetic resin for the tube. This resin has the property of allowing gas to pass through it and repelling liquids. This characteristic makes it impossible for anything other than air to enter the tube from the outside. Moreover, since the tube can take many forms, it can be inserted into patients with external auditory canal stenosis. The discomfort after inserting this tube also disappears.

鼓膜に装着し易いように。3 (Means for solving the problem) In order to achieve the above purpose, the entire tube is made of water-repellent synthetic resin,
For easy attachment to the eardrum.

みかつ固定するために付けた本発明の重要部分である。The configuration was as shown in Figures 2 and 3. The recess 4 is an important part of the present invention, provided to sandwich and fix the eardrum.
尚、チューブの形態はどのようにも作成可能である。Note that the tube can be created in any shape.

ーブである。(Function) The water-repellent synthetic resin tube of the present invention inserted into the eardrum is firmly fixed at the lateral part several hours after insertion. In this state, external fluids and bacteria are prevented from entering the middle ear. Impenetrable. In addition, since gas can pass freely through the tube, ventilation within the middle ear occurs smoothly, making it a safe and ideal tube with great therapeutic effects.

時に。(Effects of the Invention) The tube of the present invention is made of water-repellent synthetic resin, which allows the tube to be shaped freely, and by making it easy to wear and thin, even inexperienced doctors can perform the operation easily (middle ear tube insertion). , and no longer requires skill. Furthermore, after the tube of the present invention is inserted, the tube allows gas to pass through it but is water repellent to liquids, so at the same time the air pressure inside and outside the middle ear cavity becomes the same.
