Description

本発明は、周縁部及び隔離部で区画された複数の収容室を有する複室容器に関するものである。   The present invention relates to a multi-chamber container having a plurality of storage chambers partitioned by a peripheral edge portion and an isolation portion.

人体等に供給される２種類以上の薬液・薬剤を、混合変化を避けるために、隔離部により分離して容器に保存し、投与直前に容器を押圧して隔離部による分離を解除して薬液、薬剤を混合できる複室容器が知られている。
このような複室容器を使用する場合、隔離部の解除を忘れても、中空針で口栓を挿通すれば、口栓と連通する薬液収容室の薬液のみが投与されてしまうという医療事故を引き起こす可能性がある。 In order to avoid mixing changes, two or more types of chemicals / drugs supplied to the human body, etc. are separated and stored in a container by an isolation part, and the container is pressed immediately before administration to release the separation by the isolation part. A multi-chamber container capable of mixing drugs is known.
When using such a multi-chamber container, even if you forget to release the isolation part, if you insert the plug with a hollow needle, only the drug solution in the drug solution storage chamber that communicates with the plug will be administered. May cause.

そこで、口栓に連通する薬液収容室と、口栓との間に閉鎖部材を設け、この閉鎖部材の強度を、隔離部と同等かそれ以上の強度に設定して、容器の押圧による隔離部の解除と同時又はその解除後でなければ閉鎖部材を解除することができないような構造が提案されている。
特開2004-344442号公報 特開2005-28036号公報 Therefore, a closing member is provided between the medical solution storage chamber communicating with the stopper and the stopper, and the strength of the closing member is set to be equal to or higher than that of the isolation part, and the isolation part by pressing the container A structure has been proposed in which the closing member can be released only at the same time as or after the release.
JP 2004-344442 A JP 2005-28036 A

ところが、前記構造の複室容器では、隔離部が先に解除されてしまって、薬剤収容室、薬液収容室が連通してしまうと、１つの大きな薬液収容室ができてしまい、外から押圧を続けても力が分散されて、前記閉鎖部材を解除するのに必要な力が得られないことがある。
したがって、使用者は、通常よりも大きな力をかけないと閉鎖部材を解除できないことになる。 However, in the multi-chamber container having the above structure, when the isolation portion is released first and the medicine storage chamber and the chemical solution storage chamber communicate with each other, one large chemical solution storage chamber is formed, and pressing from the outside is performed. Even if it continues, force may be disperse | distributed and the force required in order to cancel | release the said closure member may not be obtained.
Therefore, the user cannot release the closing member unless a force larger than usual is applied.

このように隔離部が先に解除された場合と、そうでない場合とで、かける力が異なると、使用者の使い勝手が悪くなり、使用に不安を抱かせることにもなる。
そこで、本発明は、いつの場合でも所定の力で隔離部及び閉鎖部材を解除することができる複室容器を提供することを目的とする。 Thus, if the applied force is different between the case where the isolation unit is released first and the case where it is not, the user's usability is deteriorated and the user is anxious about use.
Then, an object of this invention is to provide the multi-chamber container which can cancel | release a isolation | separation part and a closure member by predetermined force at any time.

本発明の複室容器は、薬液収容室と、薬剤収容室と、両室の間に介在される解除可能な隔離部と、前記薬液収容室の中に設けられた気体室と、前記薬液収容室の外部から前記気体室に連通する口栓とを備え、前記気体室内の気体と、前記薬液収容室内の薬液とを隔離するための、前記気体室の押圧で解除可能な閉鎖部材が設けられ、前記隔離部のシール力は、前記閉鎖部材のシール力よりも弱く設定され、前記口栓の側面には、前記薬液収容室内に面して薬液流通孔が形成され、前記閉鎖部材は、前記薬液流通孔を塞いでいるものである。
この構造であれば、容器の気体室の部分を押圧すると、（１）隔離部が先に解除される場合と、（２）閉鎖部材が先に解除される場合とがある。 The multi-chamber container of the present invention includes a chemical solution storage chamber, a drug storage chamber, a releasable separating portion interposed between both chambers, a gas chamber provided in the chemical solution storage chamber, and the chemical solution storage A closure member that is connected to the gas chamber from the outside of the chamber, and is provided with a closing member that can be released by pressing the gas chamber for isolating the gas in the gas chamber from the chemical solution in the chemical solution storage chamber. The sealing force of the isolation portion is set to be weaker than the sealing force of the closing member, and a chemical solution circulation hole is formed on the side surface of the plug so as to face the chemical solution storage chamber. The chemical solution circulation hole is blocked .
If it is this structure, if the part of the gas chamber of a container is pressed, (1) the isolation | separation part may be cancelled | released first, and (2) the closure member may be cancelled | released first.

前記（１）の場合には、隔離部が先に解除されて１つの大きな薬液収容室ができてしまっても、気体室はそのまま残っているので、閉鎖部材を解除するために要する、気体室を押圧する力は変わりがない。従って、平常の力で気体室を押圧することによって閉鎖部材を解除することができる。
前記（２）の場合には、閉鎖部材が先に解除されることによって、薬液収容室と気体室とが連通して、薬液収容室内の薬液と気体とが混合された状態になるが、薬液収容室内の薬液と気体との合計の体積は、変わりない。従って、混合された気体室と薬液収容室とを、いつもの力で押圧することによって、隔離部を解除することができる。 In the case of (1), the gas chamber remains as it is even if the isolation part is first released and one large chemical solution storage chamber is formed, so the gas chamber required for releasing the closing member The force to press is unchanged. Therefore, the closing member can be released by pressing the gas chamber with a normal force.
In the case of (2) above, the closing member is released first, whereby the chemical solution storage chamber and the gas chamber communicate with each other, and the chemical solution and gas in the chemical solution storage chamber are mixed. The total volume of the chemical solution and gas in the storage chamber does not change. Therefore, the isolation portion can be released by pressing the mixed gas chamber and the chemical solution storage chamber with the usual force.

したがって、本発明によれば、使用者は、普段の力を加えるだけで、隔離部及び閉鎖部材を両方とも解除することができる。
なお、前記隔離部のシール力は、閉鎖部材のシール力よりも弱くなっているので、気体室を外部から押圧すれば、隔離部が先に解除されることが多くなる。なお、万一、閉鎖部材が先に解除された場合でも、引き続いて隔離部が解除されやすいのは、前述したとおりである。 Therefore, according to the present invention, the user can release both the isolation part and the closing member only by applying ordinary force.
Incidentally, the sealing force of the isolation portion, since weaker than the seal strength of the closure member, if pressed gas chamber from the outside, standoff increases to be released first. As described above, even if the closing member is released first, the isolation part is easily released subsequently.

また、前記口栓の側面には、前記薬液収容室内の薬液に面して薬液流通孔が形成され、前記閉鎖部材は、前記薬液流通孔を塞ぐもの（可撓性の膜など）である。これにより、前記閉鎖部材が開放された後、薬液を薬液収容室から口栓に流通させることができるので、混合薬液を、口栓から供給し、点滴などに用いることができる。 Further, the side surface of the spout is medical liquid flow hole is formed facing in the chemical of the drug solution storage chamber, said closure member is intended to block the medical liquid flow hole (such as a flexible membrane). Thereby, after the said closure member is open | released, since a chemical | medical solution can be distribute | circulated from a chemical | medical solution storage chamber to a stopper, a mixed chemical | medical solution can be supplied from a stopper and can be used for drip etc.

以下、本発明の実施の形態を、添付図面を参照しながら詳細に説明する。
図１は、本発明の複室容器としての二室式バッグ１の概略正面図である。図２は、二室式バッグ１の側断面図である。
この二室式バッグ１は、医療用として許可されたプラスチック（ポリマー、エラストマーを含む）のフィルムを重ねて融着することにより形成され、薬液収容室Ｓ１と、薬剤収容室Ｓ２と、両室を取り囲む周縁部２とが設けられている。両室の間には、周縁部２の延長である、解除可能な隔離部３が存在している。 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a schematic front view of a two-chamber bag 1 as a multi-chamber container of the present invention. FIG. 2 is a side sectional view of the two-chamber bag 1.
This two-chamber bag 1 is formed by stacking and fusing plastic films (including polymer and elastomer) that are approved for medical use. The two-chamber bag 1 includes a chemical solution storage chamber S1, a drug storage chamber S2, and both chambers. Surrounding peripheral edge 2 is provided. Between both chambers, there is a releasable separating part 3 which is an extension of the peripheral part 2.

前記薬剤収容室Ｓ２には、薬液又は薬液以外の物質、例えば粉末剤等が収容される。
さらに、薬液収容室Ｓ１を取り囲む周縁部２の一部には、前記薬液収容室Ｓ１の中に挿入される円筒状の口栓４が設けられている。口栓４は、ポリエチレンなどの材料で形成されている。
この口栓４の、薬液収容室Ｓ１側の先端部には、清浄な空気を収容した可撓性の気体室５が装着されている。 The drug storage chamber S2 stores a chemical solution or a substance other than the chemical solution, such as a powder agent.
Furthermore, a cylindrical plug 4 inserted into the chemical solution storage chamber S1 is provided at a part of the peripheral edge portion 2 surrounding the chemical solution storage chamber S1. The plug 4 is made of a material such as polyethylene.
A flexible gas chamber 5 containing clean air is attached to the distal end of the plug 4 on the side of the chemical solution storage chamber S1.

気体室５は、二室式バッグ１と同様、プラスチックフィルムを重ねて融着することにより形成したものである。
気体室５及び口栓４は、薬液収容室Ｓ１内の薬液と隔離されており、気体室５に入っている空気は、後述する閉鎖部材６を破らない限り、薬液収容室Ｓ１内の薬液と接触することはない。 As with the two-chamber bag 1, the gas chamber 5 is formed by stacking and fusing plastic films.
The gas chamber 5 and the plug 4 are isolated from the chemical solution in the chemical solution storage chamber S1, and the air contained in the gas chamber 5 is separated from the chemical solution in the chemical solution storage chamber S1 unless the closure member 6 described later is broken. There is no contact.

前記気体室５と前記薬液収容室Ｓ１との間には、前記気体室５内の空気と、前記薬液収容室Ｓ１内の薬液とを遮断するための解除可能な閉鎖部材６が設けられている。
本発明の実施の形態では、この閉鎖部材６は、口栓４の側面に形成された薬液流通用の孔７に適用されたものとなっている。
前記二室式バッグ１、気体室５、閉鎖部材６などを形成するプラスチックとしては、特にポリエチレン、ポリプロピレン等のポリオレフィンが、優れた成形性を有しており、かつ安全性が確立していることから好適に用いられる。 A releasable closing member 6 is provided between the gas chamber 5 and the chemical solution storage chamber S1 to shut off the air in the gas chamber 5 and the chemical solution in the chemical solution storage chamber S1. .
In the embodiment of the present invention, the closing member 6 is applied to a chemical solution circulation hole 7 formed on the side surface of the plug 4.
As the plastic forming the two-chamber bag 1, the gas chamber 5, the closing member 6, etc., polyolefins such as polyethylene and polypropylene have excellent moldability and safety is established. Are preferably used.

二室式バッグ１の周縁部２及び気体室５の周縁部２は、例えばヒートシールバーによる熱融着によって形成される。
この熱融着の強度には、強弱二種類あり、強い方を強シール、弱い方を弱シールという。
弱シールになっているのは、隔離部３、及び閉鎖部材６である。 The peripheral edge 2 of the two-chamber bag 1 and the peripheral edge 2 of the gas chamber 5 are formed by, for example, heat fusion using a heat seal bar.
There are two types of strength of heat fusion. The stronger one is called a strong seal and the weaker one is called a weak seal.
It is the isolation part 3 and the closing member 6 that are weakly sealed.

好ましくは、本発明の実施の形態では、隔離部３のほうが閉鎖部材６よりもシール強度が弱くなっている。
他の部分、例えば二室式バッグ１の周縁部２、口栓４と二室式バッグ１との融着部、気体室５の周縁部、口栓４と気体室５との融着部などは、すべて強シールとなっている。
弱シールの形成方法は、例えば、(1)フィルムのうち、弱シール部における内側（多層フィルムで作成する場合は当該多層フィルムの最内層）に、ポリエチレン−ポリプロピレン混合樹脂等を使用したり、(2)弱シール部に前記混合樹脂のテープを挟んだ状態で熱融着したり、(3) 弱シールの熱融着温度を、周縁部２を熱融着させる際の温度（通常の完全融着温度）よりも低く設定したりする方法などがあげられる。 Preferably, in the embodiment of the present invention, the isolation portion 3 has a lower sealing strength than the closing member 6.
Other parts, for example, the peripheral part 2 of the two-chamber bag 1, the fusion part between the stopper 4 and the two-compartment bag 1, the peripheral part of the gas chamber 5, the fusion part between the stopper 4 and the gas chamber 5, etc. Are all strong seals.
The method of forming the weak seal is, for example, (1) using a polyethylene-polypropylene mixed resin or the like on the inner side of the weak seal portion (the innermost layer of the multilayer film in the case of making a multilayer film) of the film, 2) Heat-sealing with the mixed resin tape sandwiched between the weak seals, or (3) The heat-seal temperature of the weak seals is the temperature at which the peripheral part 2 is heat-sealed (normal complete fusion) For example, a method of setting the temperature lower than the (temperature).

図３は、この二室式バッグ１の閉鎖部材６を示す要部拡大図である。
口栓４の側面の、薬液収容室Ｓ１の薬液に触れる部分には、薬液流通孔７が形成されている。そして、この薬液流通孔７をシールするためのフィルム８が、この薬液流通孔７を含む領域を被覆している。破線８１で示す部分が、薬液流通孔７を塞ぐフィルム８の弱シール部となっている。この弱シール部が破れることにより、薬液流通孔７は開放される。 FIG. 3 is an enlarged view of a main part showing the closing member 6 of the two-chamber bag 1.
A chemical solution circulation hole 7 is formed in a portion of the side surface of the plug 4 that comes into contact with the chemical solution in the chemical solution storage chamber S1. A film 8 for sealing the chemical solution circulation hole 7 covers a region including the chemical solution circulation hole 7. A portion indicated by a broken line 81 is a weak seal portion of the film 8 that closes the chemical solution circulation hole 7. When the weak seal portion is broken, the chemical solution circulation hole 7 is opened.

さらに、口栓４の薬液流通孔７の近くには、口栓４の側面からさらに盛り上がった部分９が存在している。前記フィルム８の一部は、この盛り上がった部分９にまで接している。
以上の構造の二室式バッグ１の使用方法を説明する。
使用者は、二室式バッグ１の上から、気体室５を押圧する。すると、気体室５内の圧力は、薬液収容室Ｓ１の薬液を介して、隔離部３に及ぶ。 Further, a portion 9 that is further raised from the side surface of the plug 4 is present near the chemical solution flow hole 7 of the plug 4. A part of the film 8 is in contact with the raised portion 9.
A method of using the two-chamber bag 1 having the above structure will be described.
The user presses the gas chamber 5 from above the two-chamber bag 1. Then, the pressure in the gas chamber 5 reaches the isolation part 3 through the chemical solution in the chemical solution storage chamber S1.

隔離部３のシールは、閉鎖部材６のシールよりも弱くなっているので、隔離部３が先に解除される。
隔離部３が先に解除されることによって、薬液収容室Ｓ１と薬剤収容室Ｓ２気体室５とが連通して、薬液どうしが混合された状態になるが、気体室５の体積は変わりないので、気体室５を所定の力で押圧することによって、閉鎖部材６を解除することができる。 Since the seal of the isolation part 3 is weaker than the seal of the closing member 6, the isolation part 3 is released first.
By releasing the isolation part 3 first, the chemical solution storage chamber S1 and the drug storage chamber S2 gas chamber 5 communicate with each other and the chemical solutions are mixed, but the volume of the gas chamber 5 does not change. The closing member 6 can be released by pressing the gas chamber 5 with a predetermined force.

図４は、閉鎖部材６が解除され、薬剤収容室Ｓ２内の薬液が、口栓４に流れ込んでいく様子を描いている。このとき、口栓４の盛り上がった部分９が存在するために、フィルム８は、この部分９に引っかかって、薬液流通孔７が閉じられることはなくなり、薬液の流れは確保される。
なお、気体室５を押圧すると、閉鎖部材６が先に剥離されることがある。すると、口栓４の薬液流通孔７が開通し、薬液収容室Ｓ１の薬液と、気体室５５の空気とが混ざり合う。この場合でも、隔離部３に及ぶ圧力は、閉鎖部材６が剥離される前後で基本的に変わりないので、使用者は、所定の力で気体室５を押圧することによって閉鎖部材６を解除することができる。 FIG. 4 illustrates a state in which the closing member 6 is released and the drug solution in the drug storage chamber S2 flows into the plug 4. At this time, since the raised portion 9 of the plug 4 is present, the film 8 is not caught by the portion 9 and the chemical solution circulation hole 7 is not closed, and the flow of the chemical solution is ensured.
Note that when the gas chamber 5 is pressed, the closing member 6 may be peeled off first. Then, the chemical solution flow hole 7 of the stopper 4 is opened, and the chemical solution in the chemical solution storage chamber S1 and the air in the gas chamber 55 are mixed. Even in this case, since the pressure applied to the isolation part 3 does not basically change before and after the closing member 6 is peeled off, the user releases the closing member 6 by pressing the gas chamber 5 with a predetermined force. be able to.

以上のようにして、隔離部３、閉鎖部材６ともに確実に解除することができる。
以上で、本発明の実施の形態を説明したが、本発明の実施は、前記の形態に限定されるものではない。例えば、この二室式バッグ１の閉鎖部材６の構造として、図３に示したもの以外に、次のような構造も採用できる。
図５は、口栓４の薬液流通孔７に適用されたフィルム８を示している。フィルム８は、口栓４に対して、強シールされているが、膜厚の特に薄い部分８２があり、この膜厚の薄い部分８２が弱シールの機能をもつ。 As described above, both the isolation part 3 and the closing member 6 can be reliably released.
Although the embodiments of the present invention have been described above, the embodiments of the present invention are not limited to the above-described embodiments. For example, as a structure of the closing member 6 of the two-chamber bag 1, in addition to the structure shown in FIG.
FIG. 5 shows the film 8 applied to the chemical solution circulation hole 7 of the plug 4. The film 8 is strongly sealed with respect to the plug 4, but has a particularly thin portion 82, and this thin portion 82 has a weak sealing function.

気体室５を押圧すると、フィルム８の薄い部分８２が破れ、弁が開く。その後は、図６に示すように、薬液収容室Ｓ１内の薬液が、この弁の切れ目を通して気体室５に流れ込む。
また、今までの例では、閉鎖部材６は口栓４の側面に形成されていたが、気体室５に形成されてもよい。例えば、気体室５と薬液収容室Ｓ１とをつなぐパイプを設け、このパイプに、気体室５を押したときの押圧力で開く弁を設けてもよい。 When the gas chamber 5 is pressed, the thin portion 82 of the film 8 is broken and the valve is opened. Thereafter, as shown in FIG. 6, the chemical solution in the chemical solution storage chamber S1 flows into the gas chamber 5 through the cut of this valve.
Further, in the example so far, the closing member 6 is formed on the side surface of the plug 4, but it may be formed in the gas chamber 5. For example, a pipe that connects the gas chamber 5 and the chemical solution storage chamber S1 may be provided, and a valve that opens with a pressing force when the gas chamber 5 is pressed may be provided in the pipe.

また気体室５には、空気が入っていたが、窒素ガス、炭酸ガスなど他の気体を収容しておいてもよい。
その他、本発明の範囲内で種々の変更を施すことが可能である。 The gas chamber 5 contains air, but may contain other gases such as nitrogen gas and carbon dioxide gas.
In addition, various modifications can be made within the scope of the present invention.
