Description

本発明は、気管切開をして直接挿入することにより、気管内に付着した痰等の異物を吸引・除去するために用いられる吸引用気管内チューブに関するものである。   The present invention relates to an endotracheal tube for suction that is used for sucking and removing foreign substances such as wrinkles attached to the trachea by making a tracheostomy and directly inserting it.

従来の吸引用気管内チューブには、筒状の側壁の先端を封して当該側壁で取り囲まれた中空孔として吸引路を形作ると共に、この側壁に貫通孔を形成することで、この貫通孔を吸引路（中空孔）に通じる吸引口としたものがある（例えば、特許文献１参照）。
実開昭５７−１８２４４９号公報 In a conventional endotracheal tube for suction, the tip of a cylindrical side wall is sealed to form a suction path as a hollow hole surrounded by the side wall, and this through hole is formed by forming a through hole in the side wall. There is a suction port that leads to a suction path (hollow hole) (see, for example, Patent Document 1).
Japanese Utility Model Publication No. 57-182449

しかしながら、側壁で取り囲まれた中空孔として吸引路を形作り、この吸引路内に負圧を発生させて異物を吸引・除去しようとする場合、例えば、気管内に付着した異物を持続的に吸引しようとすると、気管粘膜が吸引口に吸着してしまう虞がある。   However, when a suction path is formed as a hollow hole surrounded by a side wall and a negative pressure is generated in the suction path to try to suck and remove foreign substances, for example, continuously suck foreign substances attached to the trachea. As a result, the tracheal mucosa may be adsorbed to the suction port.

本発明の目的とするところは、異物の吸引を持続的に行っても、気管粘膜を吸着させることなく、気管内に付着した異物の安定した吸引・除去を実現することにある。   An object of the present invention is to realize stable suction / removal of foreign matter adhering to the trachea without adsorbing the tracheal mucosa even if the foreign matter is continuously sucked.

本発明である、吸引用気管内チューブは、気管に付着した異物を吸引する吸引口を有し、この吸引口に通じる吸引路が側壁で取り囲まれた中空孔として形作られ、気管切開部から直接挿入される吸引用気管内チューブであって、前記側壁に、前記吸引路に通じる外気導入孔を設けたことを特徴とするものである。   The suction endotracheal tube according to the present invention has a suction port for sucking foreign matter adhering to the trachea, and the suction passage leading to the suction port is formed as a hollow hole surrounded by a side wall, directly from the tracheostomy part. The suction endotracheal tube to be inserted is characterized in that an external air introduction hole leading to the suction path is provided in the side wall.

本発明に係る外気導入孔は、少なくとも１箇所設ければよい。また、外気導入孔を、例えば、丸孔とした場合、その内径寸法としては、約１〜４mmが挙げられる。但し、本発明に従えば、その外気導入孔は、気管粘膜が継続的な吸引によって吸引口に吸着しない程度の負圧を吸引路内に生じさせるものであればよく、かかる作用効果を奏するものであれば、その形状や内径寸法等は特に限定されるものではない。   It is sufficient that at least one outside air introduction hole according to the present invention is provided. Moreover, when the outside air introduction hole is, for example, a round hole, the inner diameter dimension is about 1 to 4 mm. However, according to the present invention, the outside air introduction hole is not limited as long as it generates a negative pressure in the suction passage so that the tracheal mucosa is not adsorbed to the suction port by continuous suction, and has such an effect. If it is, the shape, the inner diameter, and the like are not particularly limited.

本発明である、吸引用気管内チューブは、チューブポンプやピストンポンプ等に代表されるポンプを備える吸引器に繋がり、気管内に付着した異物を収集ビン等に吸引・除去する。なお、本発明である、吸引用気管内チューブは、異物の吸引を持続的（連続的）に行う場合、断続的に行う場合のいずれにも適用可能であるが、吸引を持続的に行う場合に特に有効である。   The suction endotracheal tube according to the present invention is connected to an aspirator including a pump represented by a tube pump, a piston pump, and the like, and sucks and removes foreign matter adhering to the trachea to a collection bottle or the like. Note that the suction endotracheal tube according to the present invention can be applied to both continuous (continuous) suction of foreign matter and intermittently, but when continuous suction is performed. Is particularly effective.

本発明によれば、気管内に挿入したとき、当該気管に面する部分と吸引路を介して対向する部分、例えば、患者が横たわった状態において、気管粘膜に接触する部分に対して上側（好適には、真上）に位置する部分に前記外気導入孔を設けることが好ましい。   According to the present invention, when inserted into the trachea, the portion facing the trachea via the suction path, for example, the portion lying in contact with the tracheal mucosa when the patient lies down (preferably In this case, it is preferable to provide the outside air introduction hole in a portion located directly above.

更に、本発明では、前記側壁の後端に、医療用テープ等を介して人体の表面に固定され、気管内の前記吸引口を位置決めするための固定盤を設けることが好ましい。   Furthermore, in the present invention, it is preferable to provide a fixed plate for positioning the suction port in the trachea that is fixed to the surface of the human body via a medical tape or the like at the rear end of the side wall.

本発明によれば、気管内の異物が吸引口を通して吸引路内に導入されるのに併せて、外気導入孔からも外気が導入されるため、持続的に吸引を行った場合でも、吸引路内に生じる負圧はほぼ一定の圧力に抑制される。   According to the present invention, since the foreign air in the trachea is introduced into the suction path through the suction port, the outside air is also introduced from the outside air introduction hole. The negative pressure generated inside is suppressed to a substantially constant pressure.

従って、本発明によれば、異物の吸引を持続的に行っても、気管粘膜を吸着させることなく、気管内に付着した異物の安定した吸引・除去を実現することができる。   Therefore, according to the present invention, it is possible to realize stable suction / removal of the foreign matter adhering to the trachea without adsorbing the tracheal mucosa even if the foreign matter is continuously sucked.

また、本発明によれば、かかる外気導入孔を気管に面する部分と吸引路を介して対向する部分に設ければ、異物が外気導入孔を塞ぎ難くなるため、気管粘膜の吸着防止に有効である。   In addition, according to the present invention, if such an outside air introduction hole is provided in a portion facing the trachea via the suction path, it is difficult for foreign matter to block the outside air introduction hole, which is effective in preventing adsorption of the tracheal mucosa. It is.

更に、本発明において、前記側壁の後端に、医療用テープ等を介して人体の表面に固定され、気管内の前記吸引口を位置決めするための固定盤を設ければ、吸引口に対する固定盤の位置（距離）や向きを調整することで、気管壁に対して吸引口を自由に位置決めすることができる。また、固定盤の位置や向きを調整した結果的として、気管壁に対して外気導入孔も好適な位置に配置することができる。   Furthermore, in the present invention, if a fixing plate is provided at the rear end of the side wall through a medical tape or the like and is fixed to the surface of the human body for positioning the suction port in the trachea, the fixing plate for the suction port By adjusting the position (distance) and direction, the suction port can be freely positioned with respect to the tracheal wall. Further, as a result of adjusting the position and orientation of the fixed platen, the outside air introduction hole can also be arranged at a suitable position with respect to the trachea wall.

以下、図面を参照して、本発明である、吸引用気管内チューブの一形態を詳細に説明する。   Hereinafter, an embodiment of the endotracheal tube for suction according to the present invention will be described in detail with reference to the drawings.

図1(a),(b)はそれぞれ、本発明の一形態である吸引用気管内チューブ（以下、「気管内チューブ」という）1をその上方から模式的に示す斜視図及び、同気管内チューブ1のＸ−Ｘ断面図である。同気管内チューブ1が採用される吸引システム100を例示する模式図である。更に、図3(a),(b)はそれぞれ、図2の要部断面図及び、同図(a)のＹ−Ｙ断面図である。   1 (a) and 1 (b) are respectively a perspective view schematically showing an endotracheal tube for suction (hereinafter referred to as “intratracheal tube”) 1 according to one embodiment of the present invention, and an intratracheal tube. FIG. 3 is a cross-sectional view of the tube 1 taken along line XX. 1 is a schematic view illustrating a suction system 100 in which the endotracheal tube 1 is employed. 3 (a) and 3 (b) are a cross-sectional view of the main part of FIG. 2 and a YY cross-sectional view of FIG. 3 (a), respectively.

気管内チューブ1は、図1(a)に示すように、軸線Ｏを取り囲む円筒状の側壁2からなる。また、気管内チューブ1は、側壁2の先端2aを開口させて、気管粘膜Ｔmに付着した痰等の異物を吸引する吸引口Ａを構成し、図1(b)に示すように、この吸引口Ａに通じる吸引路1rが側壁2で取り囲まれた中空孔として形作られている。 The endotracheal tube 1 includes a cylindrical side wall 2 that surrounds the axis O, as shown in FIG. Further, the endotracheal tube 1, by opening the tip 2a of the side wall 2, the foreign substances such as sputum attached to the tracheal mucosa T m constitutes a suction port A for sucking, as shown in FIG. 1 (b), the The suction path 1r leading to the suction port A is formed as a hollow hole surrounded by the side wall 2.

これに対し、側壁2は、その後端2bに、医療用テープ等を介して人体に固定するための可撓性を有する合成樹脂等からなる固定盤3が設けられている。   On the other hand, the side wall 2 is provided with a fixing plate 3 made of synthetic resin having flexibility for fixing to the human body via a medical tape or the like at the rear end 2b.

固定盤3には、吸引器110を介して収集ビン120に導かれる接続チューブ130に繋がる接続端部3bが設けられている。また、接続端部3b内には、接続端部3bの後端1bに抜ける貫通孔が形成されている。即ち、固定盤3に形成された貫通孔は、吸引路1rの一部を構成する。   The fixed platen 3 is provided with a connection end 3b connected to the connection tube 130 guided to the collection bottle 120 via the aspirator 110. In addition, a through hole is formed in the connection end 3b so as to extend to the rear end 1b of the connection end 3b. That is, the through hole formed in the stationary platen 3 constitutes a part of the suction path 1r.

このため、本形態では、側壁2の先端2aが気管内チューブ1の先端1aをなし、固定盤3の後端1bが気管内チューブ1の後端をなす。なお、図1(a)に示す符号3aは、接続チューブ130の交換の際に、接続端部3bを閉じるための封止栓である。   Therefore, in this embodiment, the front end 2a of the side wall 2 forms the front end 1a of the endotracheal tube 1, and the rear end 1b of the stationary platen 3 forms the rear end of the endotracheal tube 1. Note that reference numeral 3a shown in FIG. 1 (a) is a sealing plug for closing the connection end 3b when the connection tube 130 is replaced.

吸引システム100は、図2に示すような基本構成を有する。先ず、符号110は、異物PHを吸引するためのチューブポンプ式の吸引器である。   The suction system 100 has a basic configuration as shown in FIG. First, reference numeral 110 denotes a tube pump type suction device for sucking the foreign matter PH.

吸引器110は、同図に示すように、モータＭによって回転するローラ111と、このローラ111の円周方向に間隔を空けて配置される3つの押圧ローラ112と、これらの押圧ローラ112がロータ111の回転に伴い協働して接続チューブ130を圧搾する押圧ガイド113とを有する。   As shown in the figure, the suction device 110 includes a roller 111 rotated by a motor M, three pressing rollers 112 arranged at intervals in the circumferential direction of the roller 111, and these pressing rollers 112 are rotors. And a pressing guide 113 that squeezes the connection tube 130 in cooperation with the rotation of 111.

これにより、モータＭを制御すれば、気管粘膜Ｔmに付着した痰等の異物PHは、気管内チューブ1の吸引口Ａから接続チューブ130を経て収集ビン120内に回収される。なお、接続チューブ130には、分岐管131を介して圧力センサ132が接続されている。これにより、モータＭは、圧力センサ132からの検出値に基づき、コントローラ150によってフィードバック制御される。 Thus, by controlling the motor M, the foreign matter PH such sputum attached to the tracheal mucosa T m is is collected in the collection bottle 120 through the connection tube 130 from the suction port A of the endotracheal tube 1. Note that a pressure sensor 132 is connected to the connection tube 130 via a branch pipe 131. Accordingly, the motor M is feedback-controlled by the controller 150 based on the detection value from the pressure sensor 132.

また、吸引器110によって異物PHを収集ビン120に吸引するときの圧送量（圧送速度）は、ポンプの構成やモータＭの回転等に応じて適宜変更可能であるが、例えば、50〜200cc/secを目安とする。   Further, the pumping amount (pumping speed) when the foreign substance PH is sucked into the collection bin 120 by the suction device 110 can be appropriately changed according to the configuration of the pump, the rotation of the motor M, etc., for example, 50 to 200 cc / Use sec as a guide.

気管内チューブ1は、気管切開をして気管切開部Ｄから直接挿管し、気管壁（気管粘膜Ｔm）に接触するように気管Ｔ内に留置することで使用されるものである。このため、本形態の気管内チューブ1は、図1に破線で示すように、吸引路1rを貫通する折り曲げ可能な棒状の芯材Ｃを備える。 The endotracheal tube 1 is used by making a tracheostomy, intubating directly from the tracheostomy part D, and placing it in the trachea T so as to contact the tracheal wall (tracheal mucosa T m ). For this reason, the endotracheal tube 1 of this embodiment includes a foldable rod-shaped core material C that penetrates the suction path 1r, as indicated by a broken line in FIG.

かかる芯材Ｃは、気管内チューブ1を挿管するときの案内となる。芯材Ｃは、気管内チューブ1の挿管が完了した後、吸引路1rから引き抜くことで、吸引路1rが確保される。   Such a core material C serves as a guide when the endotracheal tube 1 is intubated. After the intubation of the endotracheal tube 1 is completed, the core material C is pulled out from the suction path 1r, thereby securing the suction path 1r.

符号4は、側壁2を貫通して、吸引路1rに通じる外気導入孔である。外気導入孔4は、図3に示すように、気管Ｔ内に挿入したとき、気管粘膜Ｔmに面する部分と吸引路1rを介して対向する部分、例えば、患者が横たわった状態において、気管粘膜Ｔmに接触する部分に対して上側（好適には、真上）に位置する部分に設けられている。 Reference numeral 4 denotes an outside air introduction hole that penetrates the side wall 2 and communicates with the suction path 1r. As shown in FIG. 3, the outside air introduction hole 4, when inserted into the trachea T, is a portion facing the tracheal mucosa T m through the suction path 1 r, for example, in the state where the patient lies down upper (preferably just above) to the portion in contact with the mucosal T m is provided in a portion located.

本形態の気管内チューブ1によれば、図3(a)の矢印に示すように、気管Ｔ内の異物PHが吸引口Ａを通して吸引路1r内に導入されるのに併せて、外気導入孔4からも外気が導入されるため、持続的に吸引を行った場合でも、吸引路1r内に生じる負圧はほぼ一定の圧力に抑制される。   According to the endotracheal tube 1 of this embodiment, as shown by the arrow in FIG. 3 (a), the foreign air PH in the trachea T is introduced into the suction path 1r through the suction port A, and the outside air introduction hole Since the outside air is also introduced from 4, the negative pressure generated in the suction passage 1r is suppressed to a substantially constant pressure even when the suction is continuously performed.

従って、気管内チューブ1によれば、異物PHの吸引を持続的に行っても、気管粘膜Ｔmを吸着させることなく、気管Ｔ内に付着した異物PHの安定した吸引・除去を実現することができる。 Therefore, according to the endotracheal tube 1, even if the suction of the foreign matter PH sustainable without adsorbing the tracheal mucosa T m, to realize a stable suction and removal of foreign matter PH adhering to the trachea T Can do.

これに対し、気管内チューブ1の側壁2に外気導入孔4が存在しない場合、図4に示すように、吸引口Ａが気管粘膜Ｔmに接触する等して吸引路1r内の負圧が高まると、同図の領域Ｆに示すように、気管粘膜Ｔmの膨出部ｍtが吸引口Ａに吸着してしまう虞がある。この場合、気管内チューブは、気管粘膜Ｔmに付着した異物PHを吸引できず、所期の目的を達成することができない。 In contrast, if the side wall 2 of the endotracheal tube 1 there is no air introduction hole 4, as shown in FIG. 4, the negative pressure in the like by suction path 1r suction port A is brought into contact with the tracheal mucosa T m is increasing the, as shown in the region F in the figure, there is a possibility that the bulging portions m t of tracheal mucosa T m will be attracted to the suction port a. In this case, the endotracheal tube cannot suck the foreign matter PH adhering to the tracheal mucosa Tm and cannot achieve the intended purpose.

また、気管内チューブ1によれば、かかる外気導入孔4を気管Ｔに面する部分と吸引路1rを介して対向する部分、例えば、図3に示すように、患者が横たわった状態において、気管粘膜Ｔmに接触する部分に対して上側（好適には、真上）に位置する部分に設ければ、異物PHが外気導入孔4を塞ぎ難くなるため、気管粘膜Ｔmの吸着防止に有効である。 In addition, according to the endotracheal tube 1, the external air introduction hole 4 is opposed to the portion facing the trachea T via the suction path 1r, for example, in the state where the patient lies as shown in FIG. (preferably, immediately above) the upper to the portion in contact with the mucosal Tm be provided at a portion located, because the foreign matter PH hardly block the outside air introducing hole 4, effective for preventing adsorption of the tracheal mucosa T m is there.

更に、本発明において、前記側壁の後端に、医療用テープ等を介して人体の表面に固定され、気管内の前記吸引口を位置決めするための可撓性を有する固定盤を設ければ、気管壁に対して吸引口を位置決めすることで、結果的に、外気導入孔も好適な位置に配置することができる。   Furthermore, in the present invention, at the rear end of the side wall, if a fixing plate that is fixed to the surface of the human body via a medical tape or the like and has a flexibility for positioning the suction port in the trachea is provided, By positioning the suction port with respect to the trachea wall, as a result, the outside air introduction hole can also be arranged at a suitable position.

なお、外気導入孔4は、気管粘膜Ｔmが継続的な吸引によって吸引口Ａに吸着しない程度の負圧を吸引路1r内に生じさせるものであればよく、かかる作用効果を奏するものであれば、その形状や内径寸法を限定するものではないが、本形態に係る外気導入孔4は丸孔であって、その内径寸法としては、約2〜4mmとしている。 It should be noted that the outside air introduction hole 4 only needs to generate a negative pressure in the suction passage 1r so that the tracheal mucosa Tm is not adsorbed to the suction port A by continuous suction. For example, although the shape and the inner diameter are not limited, the outside air introduction hole 4 according to the present embodiment is a round hole, and the inner diameter is about 2 to 4 mm.

上述したところは、本発明の一形態に過ぎず、特許請求の範囲を逸脱することなく、種々の変更を加えることができる。例えば、気管内チューブ1の吸引口は、従来の気管内チューブと同様、側壁2の先端2aを封して当該側壁2に形成した貫通孔とすることもできる。また、外気導入孔4は、側壁2に対して少なくとも１箇所設ければよく、２箇所以上に設けられることは勿論である。更に、異物の吸引に用いられるポンプは、痰等の異物を吸引することができるものであれば、チューブポンプに限定されるものではなく、例えば、ピストンポンプであってもよいことは勿論である。   What has been described above is merely one embodiment of the present invention, and various modifications can be made without departing from the scope of the claims. For example, the suction port of the endotracheal tube 1 can be a through-hole formed in the side wall 2 by sealing the tip 2a of the side wall 2 as in the case of the conventional endotracheal tube. Of course, the outside air introduction hole 4 may be provided at least at one place with respect to the side wall 2 and may be provided at two or more places. Furthermore, the pump used for sucking foreign matter is not limited to a tube pump as long as it can suck foreign matter such as sputum, and of course, for example, may be a piston pump. .
