【0001】[0001]
本考案は、気管切開した患者の気管孔に装着する気管孔用カニュ−レに関する 。 The present invention relates to a tracheostomy cannula to be attached to the trachea of a tracheotomized patient.
【0002】[0002]
従来より上部気管や声門、または、それより上方の気道狹窄のため呼吸困難を 生じた患者に対しては気管切開術が適用され、手術により開孔した部位にカニュ −レを装着して気管内に空気が流れ込むようにすることは行なわれている。この カニュ−レは、肉厚約0.5〜1.0mm程度のフッ素樹脂やシリコ−ン樹脂で 形成されており、その構造は、例えば図2に示すようにフランジ状のフレ−ム6 の中央部に気管内に空気を導入するための空気導入パイプ1の端部7が固定され ており、フレ−ム6の両端部に固定用孔4が設けられている。このカニュ−レを 気管孔に装着するに当っては手術により生じた気管孔を拡げて空気導入パイプ1 を気管内に挿入し、固定用孔4にテ−プなどを通して首の周りにまわして固定し ている。 Conventionally, tracheostomy is applied to patients who have dyspnea due to airway stricture above or above the trachea or glottis, and a cannula is attached to the site opened by the operation to endotracheally. It is done to let the air flow into. This cannula is made of fluororesin or silicone resin having a wall thickness of about 0.5 to 1.0 mm, and its structure is, for example, as shown in FIG. An end portion 7 of the air introduction pipe 1 for introducing air into the trachea is fixed to the central portion, and fixing holes 4 are provided at both ends of the frame 6. To attach this cannula to the trachea, open the trachea created by the surgery, insert the air introduction pipe 1 into the trachea, and pass it through the fixing hole 4 around the neck and turn it around the neck. It is fixed.
【0003】 しかし、このような従来のカニュ−レにあっては、フレ−ム6と空気導入パイ プ1とが一体的に接合しているため、首の回施、屈伸運動が制限され、また、首 の運動によって空気導入パイプ1の先端部が動き気管粘膜に刺激又は損傷を与え る等の欠点があった。 この欠点を改良するため、図3に示すように、フレ−ム6と空気導入パイプ1 とを一体とせず、空気導入パイプ1とフレ−ム6との間に球状をした連結片8を 介在させ、首の運動が直接導入パイプの先端部に伝わるのを避け、空気導入パイ プ1の先端部による気管粘膜の刺激もしくは損傷をなるべくを与えないような工 夫がされたものが市販されているが、未だ充分満足すべきものとは云えない。However, in such a conventional cannula, since the frame 6 and the air introduction pipe 1 are integrally joined, the rotation and bending movement of the neck are restricted, Further, there is a drawback that the tip portion of the air introduction pipe 1 moves due to the movement of the neck, which causes irritation or damage to the tracheal mucosa. In order to improve this drawback, as shown in FIG. 3, the frame 6 and the air introducing pipe 1 are not integrated, but a spherical connecting piece 8 is interposed between the air introducing pipe 1 and the frame 6. In order to prevent the movement of the neck from being directly transmitted to the tip of the introduction pipe, the tip of the air introduction pipe 1 should not be used to cause irritation or damage to the tracheal mucosa. However, it cannot be said to be completely satisfactory.

【考案が解決しようとする課題】 本考案者は導入管の先端部が気管粘膜に刺激もしくは損傷を与えない気管用カ ニュ−レについて種々検討した結果、本考案を完成したもので、本考案の目的は 首の運動によっても気管内に挿入されたパイプによって気管粘膜に刺激又は損傷 を与えない気管孔用カニュ−レを提供することにある。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present inventor has completed the present invention as a result of various studies on a tracheal cannula in which the distal end portion of the introduction tube does not stimulate or damage the tracheal mucosa. The purpose of the above is to provide a tracheostomy cannula that does not cause irritation or damage to the tracheal mucosa by the pipe inserted into the trachea even when the neck is moved.
【0005】[0005]
本考案の要旨は、一方の端部は気管内に挿入されるパイプを有し、他方の端部 は空気導入用の弁を装着できるようにした管状コネクタ−よりなる弾性シリコ− ンによって構成された気管カニュ−レであって、該コネクタ−の側面部に紐状の 連結片を設け、該連結片の先端に気管カニュ−レ保持用の固定孔を設けたことを 特徴とする気管カニュ−レである。 The gist of the present invention is that one end has a pipe inserted into the trachea and the other end is constituted by an elastic silicone consisting of a tubular connector to which a valve for introducing air can be attached. A tracheal cannula, characterized in that a string-like connecting piece is provided on the side surface of the connector, and a fixing hole for holding the tracheal cannula is provided at the tip of the connecting piece. It is Les.
【0006】 すなわち、本考案においては従来のフランジ状のフレ−ムに代えて管状のコネ クタ−に空気導入パイプを設けると共に、このコネクタ−の側壁部より突設した 紐状の連結片の先端部に固定片を設けてあるので、このカニュ−レを装着し、首 を前後左右のみならず、回転などの運動をさせてもカニュ−レは可撓性を有する 弾性シリコ−ンの紐状の連結片を介して固定しているので、空気導入パイプの先 端部が気管壁に触れても気管粘膜に過度の圧迫を加え、刺戟したり、或は損傷を 生じたりすることはない。That is, in the present invention, an air introduction pipe is provided in the tubular connector instead of the conventional flange-shaped frame, and the tip of the string-shaped connecting piece projecting from the side wall of the connector. Since a fixing piece is provided on the part, the cannula is flexible not only when the neck is moved forward, backward, leftward and rightward, but also when the neck is moved forward and backward, right and left, the string of elastic silicone. Since it is fixed via the connecting piece of the air introduction pipe, even if the tip end of the air introduction pipe touches the tracheal wall, it does not apply excessive pressure to the tracheal mucosa, irritate or damage it. .
【0007】 本考案の図面について説明する。図1は本考案のカニュ−レの斜視図である。 図1においてコネクタ−2の一端に気管内に挿入される空気導入パイプ1がとり つけてあり、コネクタ−の他端5には空気導入用弁が嵌合されるようになってい る。そしてコネクタ−の側面部より紐状の連結片3が突設し、その先端部に固定 用孔4を設ける。The drawings of the present invention will be described. FIG. 1 is a perspective view of a cannula of the present invention. In FIG. 1, an air introduction pipe 1 to be inserted into the trachea is attached to one end of a connector-2, and an air introduction valve is fitted to the other end 5 of the connector. Then, a string-shaped connecting piece 3 is projected from the side surface of the connector, and a fixing hole 4 is provided at the tip thereof.
【0008】 このカニュ−レの使用に際しては気管切開を施した開孔より気管内にパイプを 導入し、固定用孔に例えばひもなどをとりつけて首の周りに固定する。コネクタ −の空気導入用弁としてスピ−チバルブをとりつけることにより会話をすること も可能となる。When using this cannula, a pipe is introduced into the trachea through a tracheotomized hole, and a string or the like is attached to the fixing hole and fixed around the neck. It is also possible to have a conversation by attaching a speech valve as an air introduction valve of the connector.
【0009】[0009]
以上述べたように、本考案においては弾性を有するシリコ−ンでカニュ−レを 固定してあるので、首の運動によって直接パイプの先端部が気管壁に触れても気 管粘膜に過度の圧迫を加え、刺戟や損傷を与えることが少なく、したがって、首 の回転や屈伸など運動がらくにできると共に長期間持続的に使用できる等の効果 を奏する。 As described above, in the present invention, since the cannula is fixed by the elastic silicone, even if the tip of the pipe directly touches the tracheal wall by the movement of the neck, the tracheal mucosa is excessively touched. It exerts less pressure and is less likely to cause irritation or damage. Therefore, it has the effect of allowing easy movement such as rotation and flexion of the neck and long-term continuous use.
