Abstract

<P>PROBLEM TO BE SOLVED: To efficiently and simply eliminate air from an infusion container which is a bag formed of flexible or soft synthetic resin film. <P>SOLUTION: A medical fluid bag 10 is formed of flexible film. The infusion bag 10 is provided with a discharge port 16 and an air releasing instrument 20 on its periphery. The air releasing instrument 20 is provided with a hydrophobic membrane filter 26 inside. The hydrophobic membrane filter 26 can be closed by a detachable cap 24. At the time of removal of air, the cap 24 is detached, and the infusion contained in the medical fluid bag 10 is pressurized from outside and makes the pressure act on the hydrophobic membrane filter 26. In consequence, the liquid is prevented from leaking by its surface tension but the air passes through the filter 26 and is discharged outside. After completion of removal of air, the cap 24 is reattached. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

この発明は可撓性若しくは軟質合成樹脂フィルムの袋体より成る輸液容器に関し、特に、輸血などの大量輸液に適したエア抜き機能を備えた輸液容器に関するものである。   The present invention relates to an infusion container made of a flexible or soft synthetic resin film bag, and more particularly to an infusion container having an air bleeding function suitable for large-scale infusion such as blood transfusion.

点滴などの輸液速度が遅い場合は輸液容器としての輸液バッグからの液体の移動は重力のみに依拠させることができるが、短時間に多量の液体の移動が必要となる輸血等の場合は輸液バッグを外部から機械的に加圧することにより積極的に液体の押し出しを必要な輸液速度を得るようにしている。出血時には、血圧低下を防ぎ、血液値を保つために、出血速度に合わせて輸液を投与し続け、また同時に輸血をし、出血速度に負けない速度で輸液（血）し続けることが重要であり、このことが救命率をあげるのである。近年の事件の一つとして、輸液（血）のスピードが間に合わず患者を助けられなかったことがクローズアップされたことがあったほどである。輸液を加圧して投与するためには、輸液バッグの加圧装置（例えば特許文献１を参照）を用いたり、シリンジによるポンピングを行なったりする。前述の装置は非常に高価であり、また後者の場合には、常に人手が必要である。   When the infusion rate such as infusion is slow, the movement of the liquid from the infusion bag as an infusion container can be relied only on gravity, but in the case of blood transfusion that requires movement of a large amount of liquid in a short time, the infusion bag By mechanically pressurizing the liquid from the outside, the liquid is actively pushed out to obtain a necessary infusion rate. During bleeding, in order to prevent blood pressure drop and maintain blood levels, it is important to continue to administer fluids according to the bleeding rate, and at the same time to transfuse and continue to transfuse (blood) at a rate that is not inferior to the bleeding rate. This increases the lifesaving rate. One of the recent incidents is that the speed of infusion (blood) was not enough to help the patient. In order to pressurize and administer the infusion solution, a pressurizing device for an infusion bag (see, for example, Patent Document 1) is used, or pumping with a syringe is performed. The aforementioned device is very expensive and in the latter case always requires manual labor.

輸液バックの製造時には、バッグ内液面の目視の容易のためバッグ内に空気が残っていると便利である。他方、輸液バッグの製造過程で空気を完全に排除することは現実的には困難である。そこで、通常輸液バッグは工場から空気を含んだ状態で出荷される。従って、輸液バッグを外部から機械的な加圧を加えて液体の強制的な押し出しを行う場合には、輸液バッグ中の空気が輸液経路を介してそのまま体内に取り込まれてしまうことになる。そこで、輸液（血）等の高速投与に際しては、その準備作業として医師若しくは看護士による輸液バッグからの空気抜き作業が必要である。また、輸液経路から空気（気泡）を自動的に行うものとして、輸液経路に気泡分離装置（バブルトラップ）を設けることも行われている（非特許文献１等参照）が非常に高価なものであり、十分に整備されているとは言えないものであり、更にこれらの機械のエアチャンバーの容量には限りがあり、これを超えてしまって輸液ルートにエアーが入ってしまった場合には、ルートを取り替える作業が必須となり、手術中の忙しい作業の中で、これがまた煩雑な作業なのである。
特開２００４−２３００３２号公報 "レンジャー血液・輸液ウォーミングセット"［online］、2007年5月25日、 NIHON KODEN、［平成19年11月8日検索］、インターネット When manufacturing an infusion bag, it is convenient that air remains in the bag for easy visual inspection of the liquid level in the bag. On the other hand, it is practically difficult to completely eliminate air in the manufacturing process of the infusion bag. Therefore, the infusion bag is usually shipped from the factory in a state containing air. Therefore, when the liquid is forcibly pushed out by applying mechanical pressure to the infusion bag from the outside, the air in the infusion bag is taken into the body as it is through the infusion route. Therefore, in the case of high-speed administration of infusion (blood) or the like, it is necessary to vent the air from the infusion bag by a doctor or nurse as a preparatory work. In addition, it is also very expensive to provide a bubble separation device (bubble trap) in the infusion route (see Non-Patent Document 1 etc.) as automatically performing air (bubbles) from the infusion route. Yes, it is not well maintained, and the capacity of the air chamber of these machines is limited, and if it exceeds this and air enters the infusion route, The task of changing the route is essential, and this is a complicated task in the busy operation during the operation.
JP 2004-230032 A "Ranger Blood / Infusion Warming Set" [online], May 25, 2007, NIHON KODEN, [November 8, 2007 search], Internet

バブルトラップによるものは輸液中に混入した空気（気泡）の自動除去を意図しているが、輸液速度が10mL/min程度と限界があり、点滴などの低速輸液作業には間に合うが、200mL/min〜300mL/min、時には400ｍL/minといった急速輸液用には空気除去能力に不足がある。さらにこれらの総計の輸液量は多い時には5000〜10000ｍLとなる場合もあるくらいである。そのため、急速輸液の場合には、輸液バッグ中の空気を排除するため針やシリンジを用いた人手による作業が必須であり、また手術が進むにつれ特に大量の輸液を必要となった場合には、手術の横で人手による脱気作業が必要であったが、極めて不効率であり、簡便な手法により輸液バッグの空気排除を行い得るようにすることが希求されていた。この発明はこの問題点に鑑みなされたもので、輸液バッグからの空気排除を効率的にかつ簡便に行いうるようにすることを目的とする。   The bubble trap is intended for the automatic removal of air (bubbles) mixed in the infusion, but the infusion speed is limited to about 10 mL / min, which is in time for low-speed infusion such as infusion, but 200 mL / min There is a lack of air removal capacity for rapid infusion such as ~ 300mL / min and sometimes 400mL / min. Furthermore, the total infusion volume of these totals may be 5,000 to 10,000 mL. Therefore, in the case of rapid infusion, manual work using a needle or syringe is essential to eliminate the air in the infusion bag, and especially when a large amount of infusion is required as the operation proceeds, Although manual deaeration was required beside the operation, it was extremely inefficient and there was a need to be able to remove air from the infusion bag by a simple method. The present invention has been made in view of this problem, and an object thereof is to enable efficient and simple air removal from an infusion bag.

この発明の輸液容器は、可撓性フィルムにて形成され、その内部に輸液を収納するための袋体と、前記袋体の外周に設けられ、一端は袋体の内部に開口する排出ポートと、弾性材にて形成され、前記袋体の外部における排出ポートの他端に設けられ袋体の内部を通常は閉鎖し、輸液セットの穿刺針により穿刺開通される栓体と、袋体の外部よりの袋体内部に収納された薬液の加圧による袋体内部からのエア抜き具とを備え、前記エア抜き具は前記加圧時に袋体内部よりの空気の通過は許容するが薬液の通過は阻止する疎水性フィルタ部材と、エア抜き時にフィルタ部材を外部に対して開放するが通常状態ではフィルタ部材を外部に対して閉塞する閉塞手段とを備える。   The infusion container of the present invention is formed of a flexible film, and a bag body for storing the infusion solution therein, an outer periphery of the bag body, and one end opened to the inside of the bag body A plug body formed of an elastic material, provided at the other end of the discharge port outside the bag body and normally closed inside the bag body, and punctured and opened by a puncture needle of an infusion set; and the outside of the bag body An air bleeder from inside the bag body by pressurizing the chemical solution stored in the bag body, and the air bleeder device allows passage of air from the inside of the bag body during the pressurization. Includes a hydrophobic filter member for blocking, and a closing means for opening the filter member to the outside during air bleeding but closing the filter member to the outside in a normal state.

フィルタ部材は疎水性メンブレンフィルタにより構成することができる。   The filter member can be composed of a hydrophobic membrane filter.

エア抜き具は袋体に設けることができるし、排出ポートに設けるようにすることも可能である。   The air bleeder can be provided in the bag body or in the discharge port.

エア抜き具はその閉塞手段によって通常状態では疎水性メンブレンフィルタ等のフィルタ部材が外部から閉塞されているため輸液は袋体内部に保持される。   Since the air bleeder normally closes the filter member such as a hydrophobic membrane filter by the closing means, the infusion solution is held inside the bag.

エア抜き時は閉塞手段を解除することでフィルタ部材が外部に対して開放され、袋体に収容された輸液を加圧することにより袋体内部の空気はフィルタ部材を通して排出されるがフィルタ部材の疎水性によって液体の通過は阻止される。   When the air is released, the filter member is opened to the outside by releasing the blocking means, and the air in the bag body is discharged through the filter member by pressurizing the infusion contained in the bag body. The nature prevents the passage of liquid.

エア抜き完了後に閉塞手段によりフィルタ部材は再び外部に対して閉塞され、袋体はエア抜き状態に保持される。   After the air bleeding is completed, the filter member is again closed against the outside by the closing means, and the bag body is held in the air bleeding state.

疎水性フィルタ部材を外部に対して開放し、袋体に収容された輸液を加圧するのみでエア抜きを簡便かつ確実に実行し、輸血などの急速輸液作業の効率化を実現することができる。また、疎水性フィルタを用いることで、エアのみを外部に排出できことに加え、外気からの細菌類の進入にも対処することができ、輸液バッグの汚染防止の観点で有利である。   By simply opening the hydrophobic filter member to the outside and pressurizing the infusion contained in the bag body, the air can be removed easily and reliably, and the efficiency of rapid infusion work such as blood transfusion can be realized. Moreover, by using a hydrophobic filter, in addition to being able to discharge only air to the outside, it is possible to cope with the entry of bacteria from the outside air, which is advantageous from the viewpoint of preventing contamination of the infusion bag.

図１において、輸液バッグ１０（本発明の袋体）は厚さ２００ミクロンといったポリエチレンフィルムなどの多層構造の可撓性フィルムよりなり、所定寸法の上下２枚のフィルム切片を外周部（剥離不能溶着部）１２において溶着して構成される。溶着部での溶着温度はポリエチレンフィルムの場合は１２０℃といった温度で、輸液バッグ１０中に輸液を密封収容した状態で薬液バッグを輸液の部位において外部から加圧しても溶着部１２でのフィルムの剥離が起こらず、溶着状態を維持する温度に設定されている。溶着部１２には懸垂孔１４が穿設され、この懸垂孔１４によって輸液バッグ１０を輸液台などに吊り下げ保持し、輸血などの輸液作業を行うことになる。尚、輸液バッグ１０を２枚のフィルム切片の溶着構造の代わりに袋状のフィルムより薬液バッグを構成することも可能である。   In FIG. 1, an infusion bag 10 (the bag of the present invention) is made of a flexible film having a multilayer structure such as a polyethylene film having a thickness of 200 microns. Part) 12 and welded. In the case of a polyethylene film, the welding temperature at the welded portion is 120 ° C., and even when the drug solution bag is pressurized from the outside at the site of the infusion solution in a state where the infusion solution is sealed and contained in the infusion solution bag 10, It is set to a temperature at which peeling does not occur and the welded state is maintained. A suspension hole 14 is formed in the welded portion 12, and the infusion bag 10 is suspended and held by the suspension hole 14 on an infusion table or the like to perform an infusion operation such as blood transfusion. The infusion bag 10 can also be constituted by a bag-like film instead of a two-film slice welding structure.

輸液バッグ１０の外周（輸液バッグ１０を輸液台などに吊り下げ保持した状態での下端位置）に排出ポート１６が設けられ、排出ポート１６は、その形態を維持しうる剛性を有した肉厚を有した合成樹脂（薬剤バッグ１０との密着性を得るため薬剤バッグ１０と同一プラスチック素材とするのが好ましい）の成形品である。排出ポート１６は両端で開口し、中間がテーパ部16-1をなし、輸液バッグ１０の外側の端部（下端）にフランジ部16-2（図１）を有した筒状に形成される。フランジ部16-2にはキャップ16-3が突当溶着され、キャップ16-2の底面開口部にはゴム栓（栓体）１８が装着される。輸血などの輸液時には輸液セットの穿刺針によりゴム栓１８を穿刺し、薬剤バッグ１０の内部空洞を輸液チューブに連通させ、輸液を行うことになる。   A discharge port 16 is provided on the outer periphery of the infusion bag 10 (lower end position in a state where the infusion bag 10 is suspended and held on an infusion table). The discharge port 16 has a wall thickness with rigidity capable of maintaining its form. It is a molded product of a synthetic resin (preferably made of the same plastic material as the drug bag 10 in order to obtain adhesion to the drug bag 10). The discharge port 16 is open at both ends, the middle forms a tapered portion 16-1, and is formed in a cylindrical shape having a flange portion 16-2 (FIG. 1) at the outer end portion (lower end) of the infusion bag 10. A cap 16-3 is abutted and welded to the flange portion 16-2, and a rubber plug (plug body) 18 is attached to the bottom opening of the cap 16-2. At the time of infusion such as blood transfusion, the rubber plug 18 is punctured by the puncture needle of the infusion set, and the infusion is performed by communicating the internal cavity of the drug bag 10 with the infusion tube.

排出ポート１６を挟んで輸液バッグ１０の反対側にエア抜き具２０が設けられる。エア抜き具２０は輸液作業の開始に先立って輸液バッグ１０からのエア抜きを行うためのもので、効率的なエア抜きのための以下のような工夫を施したものである。即ち、図２に示すように、エア抜き具２０は輸液バッグ１０の内部に一端が開放する筒状体２２と、筒状体２２の他端を開閉自在とするべく筒状体２２に装着可能なキャップ（この発明の閉塞手段）２４と、筒状体２２の内部を横切るように設けられ、薬剤バッグ１０よりの空気の通過は許容するが、薬液の通過は阻止するフィルタ部材２６とを備える。この実施形態においては筒状体２２は輸液バッグ１０を構成する上下２枚の合成樹脂フィルム切片の溶着時にこの上下の合成樹脂フィルム切片間に挟着されかつ溶着され、そのため外周部１２の溶着による輸液バッグ１０の完成状態では筒状体２２の一端は輸液バッグ１０の外周部１２に流密に一体化されている。フィルタ部材２６はディスク形状をなし、この実施形態においては公知の疎水性メンブレンフィルタであり、セルロースアセテートや、PTFEや、ポリカーボネート等を素材とし、貫通した多数の孔を形成しており、この孔の径は空気は十分な透過速度にて透過させるものになっており、かつ素材自体は疎水性であり、液体は素材表面の表面張力により保持されるため液体の通過は阻止することができるものである（疎水性メンブレンフィルタについては例えば特開２００６−３２０８４９号公報等参照）。フィルタ部材２６は保持スリーブ２８により筒状体２２の他端に流密に固定される（メンブレンフィルタのハウジング支持構造については例えば特開平６−２３８１４２号公報等参照）。そして、キャップ２４は保持スリーブ２８の外端に適当なシール材を介して螺合され、キャップ２４は脱着自在となっている。   An air bleeding tool 20 is provided on the opposite side of the infusion bag 10 across the discharge port 16. The air bleeder 20 is used to bleed air from the infusion bag 10 prior to the start of the infusion work, and is devised as follows for efficient air bleed. That is, as shown in FIG. 2, the air vent 20 can be attached to the tubular body 22 so that one end is opened inside the infusion bag 10 and the other end of the tubular body 22 can be opened and closed. And a filter member 26 which is provided so as to cross the inside of the cylindrical body 22 and allows passage of air from the medicine bag 10 but prevents passage of the chemical solution. . In this embodiment, the cylindrical body 22 is sandwiched and welded between the upper and lower synthetic resin film sections when the upper and lower synthetic resin film sections constituting the infusion bag 10 are welded. In the completed state of the infusion bag 10, one end of the cylindrical body 22 is integrated with the outer peripheral portion 12 of the infusion bag 10 in a fluid-tight manner. The filter member 26 has a disk shape and is a known hydrophobic membrane filter in this embodiment. The filter member 26 is made of cellulose acetate, PTFE, polycarbonate, or the like, and has a large number of through holes. The diameter allows air to permeate at a sufficient permeation rate, and the material itself is hydrophobic, and the liquid is retained by the surface tension of the material surface, so that the passage of the liquid can be prevented. Yes (see, for example, Japanese Patent Application Laid-Open No. 2006-320849 for a hydrophobic membrane filter). The filter member 26 is fixed in a fluid-tight manner to the other end of the cylindrical body 22 by a holding sleeve 28 (see, for example, JP-A-6-238142 for the housing support structure of the membrane filter). The cap 24 is screwed to the outer end of the holding sleeve 28 via an appropriate sealing material, and the cap 24 is detachable.

輸液バッグ１０は内部に輸液を収納し、排出ポート１６及びエア抜き具２０を装着した状態で出荷される。輸液を収容した状態においても輸液バッグ１０の内部には空気が残される。完全に空気を排除した状態で密封を行うことは技術的に困難があるし、内部に空気が残っていることで液面＝液量の確認が可能となる点で便利である。内部の薬液は、通常状態では、フィルタ部材２６を構成する疎水性メンブレンフィルタ表面をその高い表面張力により湿潤させることがなく、そのため、輸液バッグ１０の内部の輸液がフィルタ部材２６を通過することはない。また、輸液バッグ１０の移送中にフィルタ部材２６に輸液の圧力は作用することはあり得るが、メンブレンのバブルポイント値（液膜を破壊して空気をしてメンブレンフィルタの孔を通過させる圧力値）を超えることがなく、輸液バッグ内の空気は保持される。   The infusion bag 10 stores the infusion solution therein and is shipped with the discharge port 16 and the air vent 20 attached. Even in the state where the infusion solution is accommodated, air remains in the infusion bag 10. It is technically difficult to perform sealing in a state in which air is completely excluded, and it is convenient in that it is possible to check the liquid level = the amount of liquid when air remains inside. In the normal state, the internal chemical solution does not wet the surface of the hydrophobic membrane filter constituting the filter member 26 due to its high surface tension, so that the infusion solution in the infusion bag 10 does not pass through the filter member 26. Absent. Further, the pressure of the infusion may act on the filter member 26 during the transfer of the infusion bag 10, but the bubble point value of the membrane (the pressure value at which the liquid film is broken and air is passed through the membrane filter hole ) And the air in the infusion bag is retained.

輸血等の輸液作業に先立ち、エア抜きのためキャップ２４を外し、エア抜き具２０を上側にして輸液バッグ１０を保持し、薬液バッグを加圧する。加圧することにより空気のみフィルタ部材２６を介して外部に排出することができる。エア抜き完了後にキャップ２４を再装着し、完全エア抜きした状態の輸液バッグ１０とすることができ、輸血等の急速輸液作業に移行することができる。   Prior to infusion work such as blood transfusion, the cap 24 is removed for air release, the infusion bag 10 is held with the air vent 20 on the upper side, and the drug solution bag is pressurized. By applying pressure, only air can be discharged to the outside through the filter member 26. The cap 24 can be reattached after the air venting is completed, so that the infusion bag 10 can be completely vented, and the operation can be shifted to a rapid infusion operation such as blood transfusion.

図３及び図４は別実施形態を示し、排出ポート１１６に対してエア抜き具１２０を一体化した構造のもので、エア抜き具１２０（図４）の筒状体１２２は排出ポート１１６のテーパ部116-1に流密固定若しくは一体化される。筒状体１２２の内部には疎水性メンブレンフィルタ１２６が装着され、筒状体１２２の外側端部にねじ等により脱着自在なキャップ１２４が設けられる。この実施形態では薬液バッグ１０のエア抜きはキャップ１２４を外した状態で排出ポート１１６を介して疎水性メンブレンフィルタ１２６により行われる。エア抜き後はキャップ１２４をねじ部124Aにより排出ポート１１６に再装着し、ゴム栓１１８の穿刺により通常と同様な輸血等の輸液作業を実施することができる。   3 and 4 show another embodiment in which the air bleeder 120 is integrated with the discharge port 116, and the cylindrical body 122 of the air bleeder 120 (FIG. 4) is a taper of the discharge port 116. It is fixed or integrated with the part 116-1. A hydrophobic membrane filter 126 is mounted inside the cylindrical body 122, and a cap 124 that is detachable by a screw or the like is provided at the outer end of the cylindrical body 122. In this embodiment, air removal from the chemical solution bag 10 is performed by the hydrophobic membrane filter 126 through the discharge port 116 with the cap 124 removed. After the air is released, the cap 124 can be reattached to the discharge port 116 by the screw portion 124A, and the infusion operation such as blood transfusion as usual can be performed by puncturing the rubber plug 118.

以上の実施形態では輸液バッグからのエア抜きはキャップ24, 124を着脱自在にして輸血等の輸液作業直前に行う説明となっているが、輸液バッグ製造工程でエア抜き具12, 120によりエア抜きし、キャップ24, 124を着脱不能に装着し、その後滅菌、包装することでエア抜き不要の輸液バッグとして流通させることも場合によっては可能である。尚、滅菌はキャップ装着前の工程として実施することも可能である。また、エア抜き具の設置位置としては実施例に限定されることはなく、エア抜きしやすい適当な位置を選択可能である。   In the above embodiment, the air removal from the infusion bag is performed immediately before the infusion work such as blood transfusion with the caps 24 and 124 being detachable. In some cases, the caps 24 and 124 are attached in a non-detachable manner, and then sterilized and packaged to be distributed as an infusion bag that does not require air bleeding. Note that sterilization can also be performed as a step before the cap is attached. Further, the installation position of the air bleeding tool is not limited to the embodiment, and an appropriate position where air can be easily removed can be selected.

また、以上の説明では閉塞手段としてねじ式のキャップ24, 124の例を説明したが、それ以外に、ゴム材やフィルム材による逆止弁構造としたり、３方弁のようにコック形状したりするなど各種の変形構造とすることもできる。また粘着フィルムによるラベル構造とすることも可能である。工場出荷時に、工場出荷状態でエア抜き製品とする場合には閉塞手段として熱シール方式（剥離可能であるが再貼着はできない）を採用することも可能である。   In the above description, the screw caps 24 and 124 have been described as the closing means. However, other than that, a check valve structure using a rubber material or a film material, or a cock shape like a three-way valve can be used. For example, various deformation structures may be used. It is also possible to have a label structure with an adhesive film. At the time of shipment from the factory, when the air-bleed product is shipped from the factory, it is possible to adopt a heat seal method (which can be peeled off but cannot be re-attached) as a closing means.
