Description
本発明は、カフを有する気管チューブの簡便かつきれいな内側吸引口の製造方法に関するものである。 The present invention relates to a method for producing a simple and clean inner suction port of a tracheal tube having a cuff.
人工呼吸器を使用する患者に対して、該患者の口から気管内チューブを挿入して留置する方法、又は、手術で前頸部に気管切開口を形成し、該気管切開口から気管切開チューブを挿入して留置する方法がある（以後、気管内チューブと気管切開チューブを併せて、「気管チューブ」と称する）。
人工呼吸器から延長された呼吸用接続チューブが気管チューブに接続され、患者に空気を送り込むことで、患者は呼吸が可能となる。また、カフを設けた気管チューブもある。カフは、薄いシートで作られた気管チューブの先端付近を取り囲むドーナツ状のバルーンであり、空気で膨らませることにより、気管と気管チューブに存在している隙間を塞ぐことができる。カフの存在によって人工呼吸器から送り込まれた空気は、気管と気管チューブの隙間を通って鼻や口の方に漏れてしまうことを防止でき、確実に肺に送り込むことができる。
A method of inserting and placing an endotracheal tube from the patient's mouth to a patient who uses a ventilator, or forming a tracheostomy in the front neck by surgery, and tracheostomy tube from the tracheostomy There is a method of inserting and indwelling (hereinafter, the endotracheal tube and the tracheostomy tube are collectively referred to as “tracheal tube”).
The breathing connection tube extended from the ventilator is connected to the tracheal tube, and the patient can breathe by sending air to the patient. There are also tracheal tubes with cuffs. The cuff is a donut-shaped balloon that surrounds the vicinity of the distal end of a tracheal tube made of a thin sheet, and can be inflated with air to close a gap existing between the trachea and the tracheal tube. The air sent from the ventilator due to the presence of the cuff can be prevented from leaking through the gap between the trachea and the tracheal tube toward the nose and mouth, and can be reliably sent to the lungs.
気管チューブが留置されている患者に対しては、吸引ポンプに接続された吸引カテーテルを気管チューブの内側を通して気管内に挿入して、気管内の痰を吸引・排除することが度々行われる。この痰の吸引・排除の際には、吸引カテーテルを気管チューブの中に入れるために、その都度人工呼吸器との接続を解く必要があった。患者にとっては人工呼吸器との接続を解かれること及び吸引カテーテルが気管内に挿入されることによる刺激は、苦痛を伴うものであり、また吸引操作を行う介護者にとっても煩雑な作業であった。 For a patient who has an indwelling tracheal tube, a suction catheter connected to a suction pump is often inserted into the trachea through the inside of the tracheal tube, and the sputum in the trachea is aspirated and removed. When this sputum was aspirated and removed, it was necessary to disconnect the ventilator each time in order to place the aspiration catheter into the tracheal tube. Stimulation by the patient being disconnected from the ventilator and inserting the suction catheter into the trachea was painful and also a cumbersome task for the caregiver performing the suction operation. .
痰吸引路がチューブ壁内のチューブの伸長方向に沿って設けられた気管チューブは報告されている（参照：特許文献１）。しかし、特許文献１に記載の気管チューブは、痰の吸引口はチューブの外側と内側の両方に開口しているため、本発明のカフを有する気管チューブとは明らかに構造が異なる。 A tracheal tube in which a sputum suction path is provided along the tube extending direction in the tube wall has been reported (see Patent Document 1). However, the tracheal tube described in Patent Document 1 is clearly different in structure from the tracheal tube having the cuff of the present invention, because the spout suction port is opened both on the outside and inside of the tube.
気管チューブの壁内にチューブの伸張方向に沿って痰吸引路が設けられ、気管チューブ先端付近のチューブ内側に痰の吸引のための開口部が有することを特徴とする気管チューブが報告されている（参照：特許文献２）。しかし、特許文献２は、「先端付近のチューブ内側に痰の吸引のための開口部」の作成方法についてはいっさいの言及がない。 A tracheal tube has been reported which has a sputum suction path in the wall of the tracheal tube along the tube extension direction, and has an opening for sucking sputum inside the tube near the end of the tracheal tube. (Reference: Patent Document 2). However, Patent Document 2 makes no mention of a method of creating “an opening for sucking a bag inside the tube near the tip”.

以下、本発明を実施するための形態について説明するが、何ら請求項の範囲を限定するものではない。 Hereinafter, although the form for implementing this invention is demonstrated, the range of a claim is not limited at all.
（本発明の内側吸引口を有する気管チューブ）
本発明の内側吸引口を有する気管チューブ１の全体を図１に示す。気管チューブ１の材質は、自体公知の気管チューブと同様にポリ塩化ビニルやポリウレタン、シリコーンゴム等が用いられる。気管チューブ１は、チューブの略伸張方向（チューブの軸に実質的に平行）に痰吸引路３が設けられている。
また、内側吸引口４（痰吸引口）は、気管チューブ１の内側にのみ開口しており、その吸引口は気管チューブ１内のどのような位置にあっても良い。しかし、効率よく痰を吸引するためには気管チューブ１の先端、すなわち気管に差し込まれる側の端付近にある方が好ましい。内側吸引口４は１つでなく、痰吸引路３に沿って複数箇所に開口していても良い。痰の吸引口が気管チューブの内側にのみ開口しており、外側には開口していなくても、持続吸引法においては全く問題なく痰の吸引を行うことができることを確認している。
さらに、本発明の内側吸引口４を有する気管チューブ１は、呼吸路２、カフ５を少なくとも有し、好ましくは、痰吸引用チューブ６、吸引ポンプ用コネクタ７、おすコネクタ９、カフを膨らませるチューブ１０も有する。
(Tracheal tube having an inner suction port of the present invention)
The entire tracheal tube 1 having the inner suction port of the present invention is shown in FIG. As the material of the tracheal tube 1, polyvinyl chloride, polyurethane, silicone rubber, or the like is used similarly to a known tracheal tube. The tracheal tube 1 is provided with a soot suction path 3 in a substantially extending direction of the tube (substantially parallel to the axis of the tube).
Further, the inner suction port 4 (suction suction port) is opened only inside the tracheal tube 1, and the suction port may be located at any position in the tracheal tube 1. However, in order to suck the sputum efficiently, it is preferable that the end of the tracheal tube 1, that is, the vicinity of the end to be inserted into the trachea. The number of the inner suction ports 4 is not limited to one, and the inner suction ports 4 may be opened at a plurality of locations along the saddle suction path 3. It has been confirmed that even if the sputum suction port is opened only inside the tracheal tube and not opened outside, the sputum suction can be performed without any problem in the continuous suction method.
Further, the tracheal tube 1 having the inner suction port 4 of the present invention has at least a respiratory path 2 and a cuff 5, and preferably expands the sputum suction tube 6, the suction pump connector 7, the male connector 9, and the cuff. It also has a tube 10.
（本発明の内側吸引口を有する気管チューブが気管切開口から気管に挿管・留置されている図）
本発明の内側吸引口を有する気管チューブが気管切開口から気管に挿管・留置されている様子を図２に示す。
気管チューブ１には、気管に差し込まれる側の端である気管チューブの先端８付近にはカフ５があり、先端と反対側の端には、必要に応じて人工呼吸器等に接続できるようにおすコネクタ９（好ましくは、ＪＩＳ規格の１５ｍｍおすコネクタ）が設けてある。おすコネクタ９は気管挿管時においても体外に露出している。気管チューブ１の内腔自体が呼吸路２となる。カフ５は気管チューブ１と気管粘膜１１の間を塞ぐバルーンであり、カフ５につながる呼吸路を形成するチューブ壁内に設けられた管腔（図１及び図２では省略している）及びそれにつながるカフを膨らませるチューブ１０を通じて空気の出し入れを行うことで、膨らませたりしぼませたりすることができる。カフ５を膨らませることで、人工呼吸器から送られた空気が喉頭側に漏れるのを防止し、喉頭側から流れてきた唾液等が肺側に入り込むのをある程度防止する。
気管チューブ１の呼吸路２を形成するチューブ壁内に呼吸路２に略平行に痰吸引路３が設置されている。痰吸引路３はその断面形状は、特に限定されないが、好ましくは、円形、長方形又は半楕円形状であり、幅３ｍｍ程度、高さ１ｍｍ程度である。痰吸引路３の断面積は大きい方が痰の吸引のためには好ましいが、そのためにはチューブ壁を厚くしなければならずその分呼吸路２が狭くなる。よって、呼吸には不利になるという問題が発生するため、前述程度の大きさが好ましい。
おすコネクタ９の一態様である１５ｍｍおすコネクタ９の基部からは痰吸引路３と接続された痰吸引用チューブ６が延びており、このチューブ６の端には、痰を吸引するための吸引ポンプなどに接続できるような吸引ポンプ用コネクタ７が設けてある。
痰の内側吸引口４は、気管チューブ１の先端近くで呼吸路２側に開口している。
(The tracheal tube having the inner suction port of the present invention is intubated and placed in the trachea from the tracheostomy)
FIG. 2 shows a state in which the tracheal tube having the inner suction port of the present invention is intubated and placed in the trachea from the tracheostomy opening.
The tracheal tube 1 has a cuff 5 in the vicinity of the distal end 8 of the tracheal tube, which is the end to be inserted into the trachea, and an end opposite to the distal end can be connected to a ventilator or the like as necessary. A male connector 9 (preferably a JIS standard 15 mm male connector) is provided. The male connector 9 is exposed outside the body even during tracheal intubation. The lumen of the tracheal tube 1 itself becomes the respiratory path 2. The cuff 5 is a balloon that blocks the space between the tracheal tube 1 and the tracheal mucosa 11, and a lumen (not shown in FIGS. 1 and 2) provided in the tube wall that forms a respiratory path leading to the cuff 5, and The air can be inflated or deflated by taking in and out air through the tube 10 for inflating the connected cuff. By inflating the cuff 5, air sent from the ventilator is prevented from leaking to the larynx side, and saliva and the like flowing from the larynx side are prevented to some extent from entering the lung side.
A sputum suction path 3 is installed in the tube wall forming the respiratory path 2 of the tracheal tube 1 substantially parallel to the respiratory path 2. The cross-sectional shape of the soot suction path 3 is not particularly limited, but is preferably circular, rectangular, or semi-elliptical, and has a width of about 3 mm and a height of about 1 mm. A large cross-sectional area of the sputum suction path 3 is preferable for sucking sputum, but for this purpose, the tube wall must be thickened, and the breathing path 2 is narrowed accordingly. Therefore, since the problem of being disadvantageous for breathing occurs, the above-mentioned size is preferable.
A soot suction tube 6 connected to the soot suction path 3 extends from a base portion of the 15 mm soot connector 9 which is one embodiment of the soot connector 9, and a suction pump for sucking soot is provided at the end of the tube 6. A suction pump connector 7 is provided so as to be connectable to the above.
The inner suction port 4 of the sputum is open to the breathing path 2 near the tip of the tracheal tube 1.
以下、実施例を挙げて本発明を詳細に説明するが、本発明の範囲はこれらの実施例により限定されるものではない。 EXAMPLES Hereinafter, although an Example is given and this invention is demonstrated in detail, the scope of the present invention is not limited by these Examples.
