Description

この発明は気管切開術により頸部に気管切開孔を形成した患者に対して、その気管切開孔の保持および気管の保持・保護に関するものである。   The present invention relates to the maintenance of a tracheostomy hole and the maintenance and protection of the trachea for a patient who has a tracheostomy hole formed in the neck by tracheotomy.

呼吸機能の不完全な患者の呼吸を確保あるいは気管内の痰の吸引のため、気管切開術を行って患者の前頚部に気管切開孔を形成し、そこに気管カニューレあるいは気管切開孔保持チューブを挿入することが行われている。また、気管に狭窄がある場合にはTチューブが使われることもある。   A tracheotomy is performed to form a tracheostomy in the patient's anterior neck to ensure respiration of the patient with incomplete respiratory function or suction of the sputum in the trachea, and a tracheal cannula or tracheostomy hole holding tube is provided there. Inserting is done. T-tubes may also be used when the trachea is narrowed.

気管カニューレは図1に示すように、固定部分と湾曲管部とからなり、これを使用する場合には、固定部分をヒモで頸部に固定する必要があり煩わしく、場合によっては皮膚に擦過傷を生じること、また気管に入る湾曲管部が硬めで長いので、気管内に異物感を与えることがあった。そのため、症状の軽い患者では気管切開孔保持チューブを用いることがあった。   As shown in FIG. 1, the tracheal cannula is composed of a fixed portion and a curved tube portion. When this is used, it is necessary to fix the fixed portion to the neck with a strap, and in some cases, the skin may be scratched. Occurring, and because the curved tube part that enters the trachea is stiff and long, a foreign body sensation may be given in the trachea. For this reason, tracheostomy hole holding tubes may be used in patients with mild symptoms.

気管切開孔保持チューブは図2に示すように、気管内に入る部分が柔らかいフランジ状であるため、カニューレと比べ異物感は少ないが、痰の吸引カテーテル挿入時にその先端が気管粘膜に当たりやすく気管粘膜を刺激し咳反射を誘発したり、粘膜損傷が起きることがあった。

As shown in FIG. 2, the tracheostomy hole-holding tube has a soft flange shape in the portion that enters the trachea, so there is less foreign body sensation than a cannula, but its tip tends to hit the tracheal mucosa when the aspiration catheter is inserted. May induce cough reflexes or cause mucosal damage.
Bulletin of the Japan Tracheoesophageal Society Vol. 31, No. 3, 1980 Shinji Hashimoto, etc.

さらに気管切開孔保持チューブの場合には、前後のフランジで脱落しないように防止しているだけで、どうしても遊びがあるため、気管切開保持チューブが前後に動いてしまい、気管粘膜への刺激・損傷が起こる。遊びが少なく、かつ挿入できるサイズのチューブを選定するのは困難であった。そして、気管が狭小化してきた場合に気管を内面から保持できないという問題があった。   Furthermore, in the case of a tracheostomy hole-holding tube, there is play by simply preventing it from falling off with the front and rear flanges, and the tracheostomy holding tube moves back and forth, causing irritation and damage to the tracheal mucosa. Happens. It was difficult to select a tube having a size that can be inserted with little play. And when the trachea has been narrowed, there has been a problem that the trachea cannot be held from the inner surface.

気管に狭窄がある場合にはTチューブが用いられるが、気管に入る部分が長く、従って痰で閉塞しやすい。またチューブ自体が気管内への落ち込む危険があった。
メディカルプラクティクス Vol.8 No.10,1991年菊池功次、他
T-tubes are used when there is stricture in the trachea, but the part that enters the trachea is long and is therefore easily blocked by sputum. There was also a risk that the tube itself would fall into the trachea.
Medical Practics Vol. 8 No. 10, 1991 Koji Kikuchi, etc.

本発明は、このような従来の問題を解決しようとするもので、気管切開孔の保持、気管の保持と保護、サイズ選定の容易さ、痰での閉塞しにくさ、違和感の減少を実現することを目的とするものである。   The present invention is intended to solve such a conventional problem, and realizes retention of the tracheostomy hole, retention and protection of the trachea, ease of size selection, difficulty of blockage with a scissors, and reduction in discomfort. It is for the purpose.

本願発明の要旨は気管切開チューブであって、気管切開孔を保持する気管孔チューブの一端に外部フランジを有し、他端に気管内チューブを有することを特徴とする気管切開チューブである。   The gist of the present invention is a tracheostomy tube, which has an external flange at one end of the tracheostomy tube holding the tracheostomy hole and an endotracheal tube at the other end.

本発明にかかる気管切開チューブは気管に挿入される部分がフランジ状ではなく、チューブ状になっていることで、痰の吸引カテーテル挿入時に先端が気管粘膜に当たることを防いでいる。気管に挿入される部分がチューブ状なので、気管内での動きが最小に押さえられ、気管粘膜への刺激も少ない。またそのため、サイズ選定も厳密である必要がない。

従って、本発明によれば、症状の軽い気管切開患者に対して、気管切開孔の保持、気管の保持および保護、サイズ選定の容易さ、粘膜に与える刺激の少ない気管切開チューブを提供することができる。また気管内チューブ部分にくびれを有する場合には、挿入・抜去がより容易にできる等の効果を奏する。
In the tracheostomy tube according to the present invention, the portion inserted into the trachea is not in a flange shape but in a tube shape, thereby preventing the tip from hitting the tracheal mucosa when inserting the suction catheter of the eyelid. Since the portion inserted into the trachea is tubular, movement in the trachea is minimized, and there is little irritation to the tracheal mucosa. Therefore, size selection need not be strict.

Therefore, according to the present invention, it is possible to provide a tracheostomy tube that is less irritating to a tracheostomy patient with a mild symptom. it can. In addition, when the endotracheal tube portion has a constriction, there are effects such as easier insertion and removal.

本願発明にかかる気管切開チューブは外部フランジ、気管孔チューブ及び気管内チューブより成り、これを構成する素材としては、従来よりこの種の気管に挿入させるチューブと同様にシリコーンゴム、天然ゴム、フッ素ゴム、オレフィン系ゴム等のショア硬さ40〜90程度の柔らかさと適度な弾性を持つ素材である。外部フランジは気管孔チューブの一端に設けられており、気管切開保持チューブが気管内への落ち込みを防止するためのフランジである。気管孔チューブは前頚部に設けた気管切開孔を保持する為に切開孔に挿入されるチューブ部分であり、その長さは皮膚面から気管前壁までの距離である7〜40mm程度であって、外径は切開孔と同程度で7〜13mm程度である。そして、その他端は気管内に挿入される部分で気管の保持・保護の作用を有する。気管孔チューブ部分と気管内に挿入される部分とは通常T字状に直角に接続されているが、或いは斜めに接続されていても良い。
気管に挿入される部分がチューブ状なので、気管が閉塞してきた場合に気管を内側から支え閉塞しないよう保持できる。そして、その長さとしては片側5〜15mm程度で必要最小限の長さでよく、痰による閉塞の可能性、違和感が小さい。
本願発明にかかる気管切開チューブの外部フランジ部に発声用バルブ、呼吸訓練用の栓、人工鼻等呼吸管理器具を接続するための15Mコネクタ等を接続して使用することもできる。
The tracheostomy tube according to the present invention comprises an external flange, a tracheal tube, and an endotracheal tube, and as a material constituting the tube, silicone rubber, natural rubber, and fluororubber are conventionally used in the same manner as tubes inserted into this kind of trachea. It is a material having a shore hardness of about 40 to 90 and a suitable elasticity such as olefin rubber. The external flange is provided at one end of the tracheal tube, and the tracheostomy holding tube is a flange for preventing the tracheostomy tube from falling into the trachea. The tracheostomy tube is a tube portion that is inserted into the incision hole to hold the tracheostomy hole provided in the front neck, and its length is about 7 to 40 mm, which is the distance from the skin surface to the trachea front wall. The outer diameter is about 7 to 13 mm, which is about the same as the incision hole. The other end is a portion inserted into the trachea and has a function of holding and protecting the trachea. The tracheal tube portion and the portion inserted into the trachea are usually connected in a T shape at a right angle, or may be connected obliquely.
Since the portion inserted into the trachea is tubular, when the trachea is occluded, the trachea can be supported from the inside so as not to be occluded. The length may be about 5 to 15 mm on one side and the minimum necessary length, and the possibility of blockage by wrinkles and a sense of incongruity are small.
It is also possible to connect and use a voice valve, a breathing training plug, a 15M connector for connecting a respiratory management instrument such as an artificial nose, or the like to the external flange portion of the tracheostomy tube according to the present invention.

以下、本願発明の実施例として図面に基づいて更に具体的に説明する。
実施例1
図3は本発明にかかる気管切開チューブの斜視図であり、図4には患者が装着した場合の側断面図である。図3に示されるように、気管孔チューブ2が外部フランジ1と気管内チューブ3を接続した形状をしている。全体は気管切開孔から挿入しやすいように柔らかく弾性のある素材であるシリコーンゴムでできている。また気管切開孔の保持、気管の保持を行うことから強度も必要である。気管内チューブと気管孔チューブを折りたたむように変形させて、気管切開孔から挿入すると、気管にて気管内チューブはその弾性で自然に展開し、図4で示すように留置される。
Hereinafter, examples of the present invention will be described more specifically based on the drawings.
Example 1
FIG. 3 is a perspective view of a tracheostomy tube according to the present invention, and FIG. 4 is a side sectional view when the patient is worn. As shown in FIG. 3, the tracheal tube 2 has a shape in which the external flange 1 and the endotracheal tube 3 are connected. The whole is made of silicone rubber which is a soft and elastic material so that it can be easily inserted through the tracheostomy hole. In addition, strength is required because the tracheostomy hole is held and the trachea is held. When the endotracheal tube and the tracheostomy tube are deformed so as to be folded and inserted through the tracheostomy hole, the endotracheal tube naturally expands in the trachea and is placed as shown in FIG.

従来の気管切開孔保持チューブでは、気管内に入る部分がフランジ状になっているため、気管切開孔から痰の吸引のため吸引カテーテル4を入れるとカテーテル先端が気管後壁に当たり粘膜を刺激した(図5)。本発明品では気管内に入る部分はチューブ状になっており、カテーテル先端が気管後壁を刺激することはない(図4)。
またチューブ状になっているので全体が前後に動くことがほとんど無く、それによる刺激・粘膜損傷が大幅に軽減される。
In the conventional tracheostomy hole-holding tube, since the portion that enters the trachea has a flange shape, when the suction catheter 4 is inserted for suction of sputum from the tracheostomy hole, the tip of the catheter hits the rear wall of the trachea and stimulated the mucous membrane ( FIG. 5). In the product of the present invention, the portion that enters the trachea is tube-shaped, and the tip of the catheter does not stimulate the posterior wall of the trachea (FIG. 4).
In addition, because it is tube-like, the entire body hardly moves back and forth, thereby greatly reducing irritation and mucosal damage.

実施例2
図6に示されるように、気管内チューブの側面に変形しやすいようにくびれを持たせ、容易に挿管、抜管ができるように工夫したものである。
Example 2
As shown in FIG. 6, the side surface of the endotracheal tube is constricted so as to be easily deformed, and is devised so that it can be easily intubated and extubated.
