【０００１】
【発明の属する技術分野】
本発明は、新規なソフトバック式の経腸栄養剤保存容器に関するものである。より詳しくは、消化態、半消化態以外の濃厚な栄養剤や流動食などの経腸栄養剤を被術者に挿入する経腸栄養補給用チューブ（経鼻的または経皮的に用いる経腸栄養カテーテル）、さらに必要に応じて、栄養点滴セット（経腸栄養剤保存容器への接続部材、接続ゴム、点滴筒、ローラ・クランプ等を有する輸液セットなど）を通じて補給する際に用いられるソフトバック式の経腸栄養剤保存容器に関するものである。
【０００２】
【従来の技術】
現在、消化態、半消化態以外の濃厚な栄養剤や流動食などの経腸栄養剤を被術者に挿入する経腸栄養補給用チューブ（経鼻的または経皮的に用いる経腸栄養カテーテル）、さらに必要に応じて、栄養点滴セット（経腸栄養剤保存容器への接続部材、接続ゴム、点滴筒、ローラ・クランプ等を有する輸液セットなど）を通じて補給する際に用いられている経腸栄養剤保存容器の代表的なものとしては、上部開放型の注ぎ口付濃厚流動食専用容器が用いられている。該注ぎ口付濃厚流動食専用容器においては、該容器の下部に設けられた流動食取出口に接合された延長チューブを介して経鼻経腸栄養カテーテル等の各個の被術者の症状等に応じて選択されたカテーテルを被術者の鼻とか口から胃の中まで該カテーテルの先端部に設けられたＸ線感受部をモニタしながら差し込み、該カテーテルの先端部近傍に設けられた複数個の穴より流動食を胃に流し込むようにするものである。こうした上部開放型の注ぎ口付濃厚流動食専用容器を用いた濃厚流動食の院内感染予防に配慮した取り扱い方法としては、▲１▼毎食配膳３０分前に調整した濃厚（高栄養）流動食を消毒済みの注ぎ口付濃厚流動食専用容器に分注する。▲２▼配膳された濃厚流動食は、細菌に対し良好な培地となるので、直ちに注入開始する。手指を洗浄し汚染を防止する。▲３▼一度に注入しない場合、残量は直ちに密封し、保冷する。室温での放置は避ける。▲４▼残量を使用する場合、病棟の電子レンジで適温にし、注入する。▲５▼注入後の専用コップは下膳車に返却する。病室に放置しないこと。▲６▼経腸栄養製剤は各病棟で作製使用するが、これも細菌汚染の温床であり、取り扱いには注意を要する。▲７▼上部開放型の注ぎ口付濃厚流動食専用容器は一回（被術者に必要とされる分量）注入が終了したら、追加投与することなく、消毒した後に使用する。消毒法は８０倍ミルトン液または５０倍テゴ５１液を使用し、内側も消毒されるように空気を追い出し、１時間以上つけておく、とするものである。なお、該濃厚流動食専用容器は消毒して再使用することができるように硬質系樹脂成形品が用いられている。
【０００３】
なお、院内感染を予防する目的で、注ぎ口付濃厚流動食専用容器の注ぎ口には、該注ぎ口に嵌合する蓋体が着脱自在に取り付けられるようになってきている。そして、被術者の病状などに応じて所定容量の濃厚流動食を分注する際、および該濃厚流動食を補給した後に被術者へ水分補給（さらには、容器内部に残留する濃厚流動食を希釈化して完全に被術者に補給する目的もある）を行うために飲料水を注ぎ口より注ぎ入れる際以外は、注ぎ口は当該蓋体が装着され閉じた状態にある。
【０００４】
しかしながら、こうした上部開放型の注ぎ口付濃厚流動食専用容器では、濃厚流動食や飲料水を流動食容器に注ぎ入れる際に、看護婦などが蓋体を外して専用コップ等の容器に調整した濃厚流動食や飲料水を医者の処方箋に従って所要量になるように該濃厚流動食専用容器に付された目盛りに注意しながら注入する必要がある。そのため、この注入（分注）操作中はどうしても空気中の異物や菌が侵入するため装置内の無菌状態を保持することができず、注ぎ口よりの汚染などから菌注入の機会が増加する。また、こうした操作は、看護婦などが手作業で行う必要上、そのたびに手を消毒し、手袋やマスクをして注意深く行う必要があり、看護婦などへの負担が大きいものであった。また、濃厚流動食専用容器に注ぎ込まれる流動食や飲料水も、毎回調整を行う必要があり、調理師などへの負担が大きいほか、コスト高になり患者の医療費負担が増大するものでもあった。
【０００５】
そこで、濃厚流動食専用容器への菌の侵入による院内感染や異物の混入を防止し、かつ経腸栄養剤を予め殺菌処理して保存できるようにレトルト保存可能な容器とし、さらに取出口に未開封の保証ができるように未開封保証構造を設けた、ソフトバッグ式の経腸栄養剤保存容器が使われるようになってきている。
【０００６】
こうした従来のソフトバック式の経腸栄養剤保存容器では、経腸栄養剤を所定量封入した後、１２１℃×３０分間滅菌処理されている。そして、該経腸栄養剤保存容器本体の下部に取り付けられた経腸栄養剤取出口を有する硬質樹脂製の経腸栄養剤取出用部材には、内容物が無菌状態にあり、該内容物の正当性、安全性等を証明するためのキャップ（未開封証明構造物）が装着されており、使用時に該キャップを切り離して開栓し、これに連結チューブを接続することで、無菌系を保証しようとするものである。
【０００７】
しかしながら、水分補給するには、該ソフトバック式の経腸栄養剤保存容器の上部を消毒したハサミ等でカットし、この切り口より飲料水を適当な注入器により注ぎ込む必要があった。そのため、一旦、経腸栄養剤保存容器の上部をカットした後は、かかる切り口は開放したままであり、該開放部からの菌の侵入の機会が多く院内感染や異物混入のおそれが残っているのが現状である。
【０００８】
また、この経腸栄養剤取出口を有する硬質系樹脂製の経腸栄養剤取出用部材は、軟質系樹脂製の経腸栄養剤保存容器本体に、通常は熱シールにより溶融接着して取り付けられている。この異種材質同士の熱シールでは本体の外周縁部のシール部分に比して、十分な接着強度が得られにくく、内容物の封入や滅菌処理時、さらにはその後の移送運搬時や取り扱い時等に、外的負荷（特に滅菌処理）が加えられることで、経腸栄養剤取出用部材と経腸栄養剤保存容器本体との接着部分では十分なシール状態が保たれず、内容物が当該接着部分より漏れ出すとした問題があった。
【０００９】
【発明が解決しようとする課題】
そこで、本発明の目的は、上記問題点に鑑み、ソフトバック式の経腸栄養剤保存容器において、水分補給後にも異物や菌の侵入を防止することができ、また、内容物の液漏れの生じないソフトバック式の経腸栄養剤保存容器を提供するものである。
【００１０】
【課題を解決するための手段】
本発明者らは、上記目的を達成すべく、ソフトバック式の経腸栄養剤保存容器に関し鋭意検討した結果、上部に２重の封止構造を設けることで、水分補給後にも異物や菌の侵入を効果的に防止できるので院内感染の予防ができるとともに、経腸栄養剤保存容器本体の一部を用いて取出口を形成することで、シール接着する際に強度のバラツキがなく、一定の接着強度を確保することができるため、予定する外的負荷量（例えば、ＪＩＳなどで要求される量）の範囲内では、なんら液漏れを起こすことがない経腸栄養剤保存容器を得ることができることを見出し、かかる知見に基づき本発明を完成するに至ったものである。

【発明の実施の形態】
本発明のソフトバック式の経腸栄養剤保存容器は、本体上部にレトルト保存用の第１封止部と使用時に異物や菌の侵入防止用の第２封止部が形成されてなり、本体下部に未使用保証構造の取出口を有する突出部が形成されてなることを特徴とするものである。
【００３６】
以下に、本発明の実施の形態を図面を用いて詳細に説明する。
【００３７】
図１は、本発明のソフトバック式の経腸栄養剤保存容器の代表的な一実施形態を表す概略図である。
【００３８】
図１に示すように、本実施形態のソフトバック式の経腸栄養剤保存容器101には、本体上部にレトルト保存用の第１封止部103と使用時に異物や菌の侵入防止用の第２封止部105が形成されており、本体下部に未使用保証構造（開封構造を含む）の取出口を有する突出部107が形成されている。
【００３９】
また、前記第１封止部103と第２封止部105の間に上部切り込み部109が設けられている。これにより、図中に示す破線に沿って第２封止部105に並行に切り裂くことができ、上部の第１封止部103を取り除くことができる。
【００４０】
なお、本体上部にレトルト保存用の第１封止部103は、本体上部を含む本体の全周縁部にわたって、例えば、熱シールまたは高周波シールにより溶融接着されたシール構造のレトルト保存用の第１封止部103およびこれに連通する全周縁部にわたるレトルト保存用の周縁封止部111が形成されている。また、レトルト保存用の周縁封止部111のうち、容器本体上部であって、上記２重の封止部103、105が設けられていない封止部111の軸線ないしその近傍には、本経腸栄養剤保存容器101をフック等に吊して支持するための穴112があけられている事が望ましい。すなわち、上記２重の封止部103、105を容器本体上部の端から端まで全体にわたって設けてもよいが、むしろ水が簡単に注入できる程度の範囲に止めるのが、支持用の穴112を形成でき機能的でもあり、また開封時に異物や菌の侵入を最小限に止めることができる点からしても優れている。
【００４１】
また、本実施態様による第２封止部105は、開閉自在なジッパー式のシール構造（開閉自在なジッパー式のシール構造としては、ジッパー付き食品保存袋「ジップロック」（登録商標）で用いられているのと同様の構造が例示できる。）を有するものである。当該第２封止部105を設けることにより、本体111内の内容物である経腸栄養剤を取出口より、例えば、栄養点滴セット（輸液セット）、経腸栄養チューブ（カテーテル）を通じて被術者に補給した後に、従来は、ソフトバック式の経腸栄養剤保存容器の上部をカットして水分を注入していたが、本実施態様では、先述したように、図中に示す破線に沿って第２封止部105に並行に切り裂き、上部の第１封止部103を取り除き、当該第２封止部105を開封し、ここより必要な水分を注入すればよく、注入後は、当該ジッパー式の第２封止部105を簡単かつ素早く指でパチパチと確実に閉じ、指先の感触で密閉された感じがわかるので、閉め忘れがなく以後の異物や菌の侵入を防止することができるのである。なお、本実施態様による第２封止部105である開閉自在なジッパー式のシール構造を有する容器（バッグ）は、フィルム成形工程で、該フィルムを延伸して巻きとる捲取ロールの所定の位置に適当な大きさの溝部を設けて凸部を有するフィルムを形成し、同様にして、該凸部に対応する凹部を有するフィルムを形成する事ができ、これらを重ね合わせて適当な金型で打ち抜き、周縁部を熱シールで溶融接着することで、所望の開閉自在なジッパー式のシール構造を有する容器（バッグ）を作る事ができる。また、上記したように一体的に開閉自在なジッパー式のシール構造を有する容器（バッグ）を製造しなくとも、本体部分と当該開閉自在なジッパー式のシール構造を有する本体上部とを別々に製造し、後で熱ないし高周波等により溶融接着して一体化させて所望の容器（バッグ）を製造してもよい。この際、延伸方向が該ジッパーの長手方向となるようにして製造しておくことで、切り込み部から、切る方向（図１に破線で示す方向）の指向性が製造時に付与されるため、極めて簡単に切る事ができる（なお、このことは、後述する本体下部の突出部に設けた切り込み部においても同様におこなうことができる。）。
【００４２】
なお、本発明の経腸栄養剤保存容器では、その製造方法に関しては、何ら制限を受けるものではなく、従来既知の製造技術を適宜組み合わせて製造することができる事は言うまでもない。
【００４３】
なお、本発明では、上記実施形態のほか、前記第２封止部を図２に示すような他の実施形態とすることによっいても所期の目的を達成することができる。
【００４４】
すなわち、図２に示すように、本発明の他の実施態様としての第２封止部205は、栄養分保存容器本体202に一端が、例えば、熱融着などにより接着支持された弾性基部片207とその先端に設けられた落下菌や異物の侵入を防止する弁体部位209とからなる構造を有する。該弁体部位209は、図２の破線で示すように、弾性基部片207を起点にして上に持ち上げることができ、離せば元の状態（図２の実線で示す弁体部位209の状態）に戻る。そのため、熱ないし高周波シール等により融着されたレトルト保存可能なように封止された第１封止部203を切り取った後に、該弁体部位209を持ち上げて水分を注入した後、元の状態に戻すことで、異物や菌の侵入（特に、落下菌や異物の侵入）を封止（防止）することができる。
【００４５】
なお、本発明では、上部に設けられた２重の封止部は、上記実施形態に示すものに限定されるものではなく、栄養分保存容器に封入された内容物を取出口より取り出した後に、前記第１封止部と第２封止部の間を切断して、内側の第２封止部を開いて水分を注ぎ込んだ後、該第２封止部を閉じて、異物や菌の侵入を防止することができるように形成されているものであれば、特に制限されるものではなく、従来既知の封止構造を適宜選択して利用することができる。
【００４６】
次に、前記突出部107に形成された取出口の未開封保証構造としては、該突出部107の外周縁部113がシールされ、該突出部107の先端シール部115よりも容器本体102側の側面シール融着部に下部切り込み部117を設けた構造によって構成されている。すなわち、下部切り込み部117より、図１の突出部107に示す破線に沿って切り裂く（＝開封する）ことで、突出部107に取出口（当該破線の位置に作られる切り口）を形成することができる。従って、未開封では取出口（切り口）は形成されておらず、内容物の安全性は保証されるものである。一方、切り裂いた後は開封部を閉じて元に戻すことはできず、未開封での内容物の未使用性も保証される。
【００４７】
さらに、本発明では、前記突出部には、開封された取出口（開封時に形成される切り口）に系外の接続部材を導入し（差し込み）易くするための挿入ガイド機構、特に取出口を開口させるための機構が設けられている事が望ましい。本実施態様では、前記取出口を開口させるための機構として、図１（Ａ）および図１（Ｂ）（図１のＡ−Ａ′線に沿った断面拡大図）に示すように、切り込み部117よりも本体102側の突出部107に、該突出部107の軸線Ｌに直交する面内に延びるように、少なくとも１個、好ましくは２〜５個（図１では４個を例示）の凸部（ないし凹部）119が形成されている。かかる構造を設けることで、突出部107に示す破線に沿って切り裂いた（＝開封した）状態では、図１（Ｃ）に示すように、当該取出口（切り口）は閉じた状態になって場合に、図１（Ｂ）のＡ−Ａ′線に沿った断面拡大図に示す矢印の方向に親指と人差し指とで押すことで、確実に開口する方向に力が向かうようにできるため、図１（Ｅ）のような全体が曲がった状態になることなく、図１（Ｄ）に示すように、取出口（切り口）を開口状態にすることができる。さらに、本発明では、該突出部107の軸線Ｌに並行に面内に延びるように凸部（ないし凹部）を形成することもできるが、該突出部107の軸線Ｌに直交する面内に延びるように凸部（ないし凹部）を形成することで、系外の接続部材を導入した際に内容液を流出しにくくする効果を奏するほか、切り込み部から切り裂く場合にも、該凸部（ないし凹部）がガイド的な役割をし、該に凸部（ないし凹部）に沿って切り裂ける利点を有する。
【００４８】
また、突出部の経腸栄養剤流路内部には、系外の接続部材を導入した（差し込んだ）後に抜けにくいように、凹凸形状やテーパーにしてもよい。すなわち、現在市販されている多くの系外の接続部材は、例えば、図６に示すように、（１）略テーパー状の円柱形状の先端部が、経腸栄養剤保存容器の突出部607の取出口（切り口）に導入し易いように斜めにカットされた系外の接続部材620や、図７に示すように、（２）特にテーパーを設けていない真っ直ぐな円柱形状の先端部が、経腸栄養剤保存容器の突出部707の取出口（切り口）に導入し易いように斜めにカットされた系外の接続部材720などがある。したがって、こうした系外の接続部材に対応する経腸栄養剤保存容器の突出部では、該突出部の経腸栄養剤流路の内周面と系外の接続部材の外周面とが接触面を多くかつ突出部が系外の接続部材を押さる力を利用して突出部から系外の接続部材が脱離することなく、液漏れを防止する事ができるように、例えば、図６に示すように、（１）系外の接続部材620を導入したときの突出部607（特に経腸栄養剤流路）の形状が略逆テーパー状の円柱形状になるものや、図７に示すように、（２）系外の接続部材720を導入したときの突出部707（特に経腸栄養剤流路）の形状が、特にテーパーがなく真っ直ぐなの円柱形状になるものである。
【００４９】
さらに、本発明では、図８に示すように、突出部807の軸線Ｌに並行に面内に延びるように凸部819（ないし凹部）を形成することもできるが、この場合には、切り込み部817から切り裂く場合にガイドとなる凸部が図６、７に示すように切り裂き線に並行に設けられていないため、引き裂く際に切り裂き線に並行に力が加わりにくく、むしろ凸部（ないし凹部）819が切り裂く際にガイド的な働きをしてしまい該凸部（ないし凹部）819に並行に切り裂かれてしまったりして、きれいな切り口にならず、そのため液漏れが生じるほか、ひどい場合には、切り裂きが、本体まで達してしまい使いものにならなくなるおそれがあり、わざわざ消毒したハサミ等を用いて慎重に切り取る必要が生ずる。また、経腸栄養剤保存容器の突出部807に系外の接続部位820を導入したときに、図８（ｃ）に示すように、突出部807と系外の接続部位820との接触面に凸部819による隙間ａができるため、経腸栄養剤や水が漏れるおそれがある。
【００５０】
また、本発明の挿入ガイド機構、特に取出口を開口させるための機構（開口化機構）としては、上記実施形態に限定されるものではなく、例えば、図１に示す凸部（ないし凹部）を形成する代わりに、前記切り込み部よりも本体側の突出部に、該突出部の軸線に直交する面内に延びるように、少なくとも１つの熱印加部ないし高周波印加部が形成されていてもよい。この場合にも、該熱印加部ないし高周波印加部は、熱硬化ないし熱架橋されて材質強度が異なるようになり、凸部（ないし凹部）と同様の働きをすることができる。同様に材質の強度を変えるものとしては、図３（Ａ）〜（Ｃ）に示すように、下部切り込み部317よりも本体側の突出部307に、該突出部307の軸線Ｌに直交する面内に延びるように、少なくとも１つの短冊状のシート状物321が外接（ないし内接）されていてもよい。好ましくは、該シート状物321の中央部323を薄くし、両端部325を厚くすることで、図３（Ｂ）の矢印で示す向きに押すことで、図３（Ｃ）に示すような開口状態を顕著に生じさせることができるものである。さらに、取出口を開口させるための機構（開口化機構）としては、図４に示すように、突出部407の経腸栄養剤流路部427に開口化部材429が保持されていてもよい。この場合の開口化部材429は、系外の接続部材を導入するまでは突出部407にあり、開口状態を保持することができものであれば、特に制限されるものではなく、図４（Ａ）、（Ｃ）、（Ｄ）に示すように、経腸栄養剤流路部427に少なくとも一部が内接する（好ましくは全周面部がぴったりと当接する）形状を有するの開口化部材429を用いることができ、具体的には、図４（Ａ）に示すように、中空の円筒（中空パイプ）形状の開口化部材、図４（Ｃ）に示すように、中実の略球状の形状ないしラグビーボール状の形状の開口化部材、図４（Ｄ）に示すように中実の円柱逆円錐台形状（逆テーパー状の逆切頭円錐形状）の開口化部材などを利用することができる。該開口化部材429は、図４（Ａ）及び（Ｂ）に示すように円柱形状のように中空のものにあっては、突出部407に（例えば、流路部に突起物を設けてこれにより係止させるなどの方法により）固定化させ、該中空部を経腸栄養剤流路部として利用することもできる。この場合には、図４（Ａ）に示すように当該中空部内径に対応する外径を有する外径も持つ接続部材420を用いる必要がある。一方、図４（Ｃ）や（Ｄ）に示すように、中実の円柱パイプまたは中実の球状物等の場合には、固定化してもよいほか、固定化することなく、系外の接続部材420を導入する際に、該接続部材420により突かれて、突出部407の経腸栄養剤流路部427から外れて、経腸栄養剤保存容器の本体側に押し出される。この場合には、開口化部材429が、経腸栄養剤流路を塞がないように経腸栄養剤よりも比重を軽くし、浮き上がるようにすることもできるほか、さらに、図４（Ｃ）及び（Ｄ）に示すように、当該開口化部材429が未開封時に設置されている経腸栄養剤流路部427上部に突出部側から保存容器本体側に向けて拡径するように逆テーパーを設けておき、開口化部材429が突出部側には下がらない構造にしてもよい。なお、本発明における取出口を開口させるための機構としては、上述したものに限定されるものではなく、従来既知の開口化機構を適宜採用することができる事は言うまでもない。
【００５１】
また、本発明の挿入ガイド機構は、上記取出口を開口させるための構造以外のの他の実施形態として、例えば、図５に示すように、下部切り込み部517より切り裂いて突出部の先端（下端）の周縁封止部515を切り取って取出口を開封する時に短冊状のシート状物527（例えば、ＰＥＴ（ポリエチレンテレフタレート）製）の先端部528が該取出口（切り口）よりも外側に出るように、該突出部507の軸線方向に延びるように、該シート状物527の一部が下部切り込み部517よりも本体側の突出部507の内面に固定されていてもよい。この場合には、該シート状物527の先端部528がガイドの役割を果たし、これに沿って系外の接続部材をスムーズに挿入することができるものである。なお、本発明における挿入ガイド機構としては、上述したものに限定されるものではなく、従来既知の挿入ガイド機構を適宜採用することができる事は言うまでもない。

また、本発明の容器側の挿入ガイド機構では、さらに、上記取出口を開口させるための構造の他の実施形態として、例えば、リブが切り込み部よりも本体側の突出部の内面に形成されていても良い。この場合には、挿入ガイド機能の他に、系外の接続部材を導入した際に、該リブにより系外の接続部材を保持でき、かつ確実にシールすることができるものである。こうしたリブ（突出部）や図１に示す凹凸部は、容器本体シートと一体的に成形しても良いが、シートの片側に突出部や凹凸形状を作ったシート材を、容器本体を張り付けて作るための２枚のシート材の内側に張り合わせた後に、容器本体用のシート材を融着等により張り付けて製造してもよい。
【００５３】
また、容器本体の周縁封止部のうち、容器本体下部から突出部に至る周縁封止部は、広く（幅を厚く）して補強することが望ましい。これは、使用時に被術者が動くなどして保存容器が引っ張られたりした場合に、当該部分が捻れたりするなどの形態変化を起こしやすく、これにより取出口が狭められたり塞がれたりすることが生じ得るおすれがあるためである。
【００５４】
また、本発明の経腸栄養剤保存容器は、前記取出口を含む前記突出部の横幅が、加熱滅菌処理によるねじれを防止し得るように広く形成されていることを特徴とするものである。
【００５５】
図９は、本発明のソフトバック式の経腸栄養剤保存容器の取出口を含む前記突出部の横幅が、加熱滅菌処理によるねじれを防止し得るように広く形成されているものの代表的な一実施形態を表す概略図である。
【００５６】
図９（ａ）に示すように、本実施形態のソフトバック式の経腸栄養剤保存容器901の取出口を含む前記突出部907の横幅は、加熱滅菌処理によるねじれを防止し得るように広く形成されている。具体的には、前記取出口を含む前記突出部907の横幅が、下記式
２≦ｙ／ｘ≦６、好ましくは、３≦ｙ／ｘ≦５
（ここで、ｘは図９（ａ）に示すように、取出口を含む前記突出部の横幅であり、ｙは図９（ａ）に示すように、経腸栄養剤保存容器本体の横幅である。）を満足するように広く形成されていることが望ましい。上記式で２＞ｙ／ｘの場合には、特に問題はないが、これに接続させる接続部材が大きなものとなり、取り扱いが不便であるほか、接続時の取出口面積が大きくなり細菌等が侵入する危険性が大きくなるほか、万一、接続部材が抜けおりた場合、大量の内容物が流れ出すため、被術者の安全性の観点から好ましくない。一方、上記式でｙ／ｘ＞６の場合には、加熱滅菌処理によるねじれを防止することが困難となり、接続部材を取り付け難く、取り付け後に、内容物がねじれにより生じた皺に沿って漏れ出す場合があるため好ましくない。
【００５７】
さらに、好ましくは、図９（ａ）に示すように、経腸栄養剤保存容器本体と突出部との間の周縁封止部は、ゆるやかなスロープ状にすることが望ましく、図９（ｂ）に示すように、こうしたスロープ状にせずにいきなりその横幅を狭めるのは、加熱滅菌処理によるねじれを生じさせやすい。そのため、下記式
０．５≦ｚ／ｘ≦１０、
好ましくは、０．７≦ｚ／ｘ≦５、
より好ましくは１≦ｚ／ｘ≦３
（ここで、ｘは図９（ａ）に示すように、取出口を含む前記突出部の横幅であり、ｚは図９（ａ）に示すように、経腸栄養剤保存容器本体と突出部との間の高さである。）を満足するように経腸栄養剤保存容器本体と突出部との間の周縁封止部は、ゆるやかなスロープ状にすることが望ましい。
【００５８】
また、経腸栄養剤保存容器901の取出口を含む前記突出部907を上記の如く広く形成する場合には、該突出部の先端シール部よりも本体側の側面シール部に切り込み部を設けた構造とし、系外の接続部材を導入し易くするための挿入ガイド機構は設けなくとも良い。これは、前記突出部907を上記の如く広く形成することで、簡単に開口させることができ、かつ系外の接続部材を導入（挿入）することができるとする利点を有するからである。
【００５９】
次に、経腸栄養剤保存容器901の取出口を含む前記突出部を上記の如く広く形成する場合には、これに対応する接続部材を用いることが望ましい。すなわち、対応する接続部材の一端が経腸栄養剤保存容器の広く形成された取出口を含む前記突出部に接合し得る構造を有し、接続部材の他端が経腸栄養補給用チューブまたは経腸栄養カテーテルと接続し得る構造を有することを特徴とするものである。
【００６０】
図１０は、本発明のソフトバック式の経腸栄養剤保存容器の取出口を含む前記突出部を上記の如く広く形成する場合に、これに対応する接続部材の代表的な一実施形態を表す概略図である。
【００６１】
図１０に示すように、本実施形態の接続部材11は、口径の異なる２つの円筒体が接合した（繋がった）形をしている。このうち口径の大きい円筒部13が前記経腸栄養剤保存容器の取出口を含む突出部に接合する側であり、この口径の大きい円筒部13側の先端部15が、開封された取出口に導入し易くするための挿入ガイド構造となっていることが望ましい。前記挿入ガイド構造としては、口径の大きい円筒部13の先端部15が、斜めにカットされた（竹を斜めに割った形に切断された）挿入開口部17を有するものである。また、口径の大きい円筒部13の中程の外周囲には、接続する際につかみやすく、また接続後に内容物の液漏れおよび抜け落ちを防止する目的で、リブ（凹凸部）23やフランジなどが適当数設けられていても良いし、外周囲表面を粗面処理してもよい。また、口径の大きい円筒部13側の先端部15は、先端に行くほどその口径が緩やかに狭まっていても良い。こうすることにより、より開封した取出口に素早く挿入することができるためである。一方、口径の小さい円筒部19は、経腸栄養補給用チューブまたは経腸栄養カテーテルと接続し得る側であり、こうしたチューブに挿入しやすいように、その先端部21は、絞ってあることが好ましい。また、口径の異なる円筒部を接合した（繋げた）形にするには、成形加工しれば、簡単に製造できるが、口径の異なる円筒部の境界部分は強度的に弱く、折れやすいため、特に口径の小さい円筒部は、肉厚を大きくしたり、スロープを設けて応力集中を避け折れ難くしても良い。
【００６２】
また、上記接続部材は、経腸栄養剤保存容器の取出口との接続部より内容物がにじみ出すのを防止し得る材料で、形成または表面処理されていることが望ましい。ここで、経腸栄養剤保存容器の取出口との接続部より内容物がにじみ出すのを防止し得る材料としては、疎水性樹脂であれば良いが、例えば、ポリエチレンテレフタレート、四フッ化エチレン樹脂（テフロン：米国のデュポン社の商品名）、ＡＢＳ樹脂（アクリロニトリル，ブタジエン，スチレンを共重合もしくはブレンドして得られる丈夫な熱可塑性樹脂）等が挙げられる。また、こうした疎水性樹脂を表面処理する場合には、その基材には、親水性樹脂を用いてもよく、表面を破水性処理（例えば、親水性樹脂による表面被覆処理など）すればよい。
【００６３】
次に、本発明の経腸栄養剤保存容器用の接続部材の他の実施の形態としては、上述したソフトバック式の経腸栄養剤保存容器の開封後の取出口に導入し易くための挿入ガイド構造部、および挿入後に接続部材が取出口から脱落するのを防止するための脱落防止構造部が設けられてなるをことを特徴とするものである。
【００６４】
本発明の経腸栄養剤保存容器用の接続部材側の挿入ガイド構造部としては、特に制限されるものではなく従来公知の挿入ガイド構造を適当に利用することができるが、好ましくは、前記容器開封後の取出口の断面形状に適合するように扁平した断面楕円形状の挿入部であることが望ましい。これは、本発明の容器開封後の取出口は、上述したようにねじ切り式のキャップ等のものを用いることなく、容器本体と一体的に形成されているため、その断面形状が扁平した断面楕円形状を有している。従って、既存の経腸栄養剤保存容器用の接続部材のように、挿入部の断面形状が円形状をしている場合には、適合性が悪くなり、気密性が十分に保持できないため、取出口の両端から内容部が漏れだしてしまったり、接続部材が抜け落ちたりするなどの問題が生じる。そのため、接続部材の挿入部の断面形状も扁平した断面楕円形状に形成することが望ましいものである。ただし、接続部材のうち、経腸栄養補給用チューブに接続される側の挿入部は、従来と同様に断面形状が円形状をしていることが望ましい。
【００６５】
また、本発明の経腸栄養剤保存容器用の接続部材側の脱落防止構造部としては、特に制限されるものではなく従来公知の脱落防止構造を適当に利用することができるが、好ましくは、接続部材の前記容器開封後の取出口への挿入部の外周上に設けられてなる鉢巻き状の突出部であることが望ましい。特に、図１に示すように容器側の突出部の内面部に凹凸形状が設けられている場合には、かかる凹凸形状に適合する突出部形状とするのが望ましい。
【００６６】
なお、本発明のソフトバック式の経腸栄養剤保存容器に使用する事のできる材料に関しては、レトルト処理することができ、四季を通じて寒暖差の厳しい条件下でも十分に長期保存ができるように、耐熱性、耐寒性、熱変動性などの特性に優れ、かつ高周波シールや熱シールができ、また加工性、切る方向への指向性を付与された材料であれば特に制限されるものではなく、従来既知のレトルトバッグ用に開発された材料等の中から適宜選択して使用する事ができるものであり、例えば、アルミまたはＳｉＯ₂蒸着のポリエステル−ナイロン−ＣＣＰの三層構造物、ナイロン−アルミまたはＳｉＯ₂蒸着のポリエステル−ナイロン−ＣＣＰの四層構造物等が例示できる。
【００６７】
また、本発明のソフトバック式の経腸栄養剤保存容器は、消化態、半消化態以外の濃厚な栄養剤や流動食（これらの栄養剤や流動食には抗生物質等の薬剤を含んでいてもよい）などの経腸栄養剤、並びに飲料水（さらにこれに適当な水溶性のビタミンＣ等の栄養剤や抗生物質等の薬剤等を溶解したものであってもよい）などの飲料用水溶液を、順々に被術者に挿通した経腸栄養補給用チューブ（経鼻的または経皮的に用いる経腸栄養カテーテル）、さらに必要に応じて、栄養点滴セット（経腸栄養剤保存容器への接続部材、接続ゴム、点滴筒、ローラ・クランプ等を有する輸液セットなど）を通じて補給する際に用いられるのものである。また、従来の上部開放型の注ぎ口付濃厚流動食専用容器のように、その都度、経腸栄養剤を調整する必要がないように、安全に長期間の保存が可能で、緊急性を要するような場合、さらには、今後の高齢化により自宅や介護施設で高度医療を受けた後に適切に経腸栄養剤を補給させる必要性が生じた場合などにも好適に対応できるものである。
【００６８】
本発明のソフトバック式の経腸栄養剤保存容器の製法に関しては、何ら制限を受けるものではなく、従来既知のソフトバック式の保存容器の製造技術を適宜利用して製造することができる。例えば、２枚のフィルムを重ね合わせて適当な金型で打ち抜き、周縁封止部（第１封止部と第２封止部部にそれぞれの内容物を注入するために該容器を横向きに倒置した状態で上部側にくる位置に未融着部分をそれぞれ残しておくのが望ましい）となる部分を熱ないし高周波等により溶融接着した後、該容器を横向きに倒置した状態で第１封止部と第２封止部部に未融着部分よりそれぞれの内容物を入れ、内容物を注入するために残しておいた未融着部分を熱ないし高周波等により溶融接着し、その後、加熱滅菌することにより、本発明のソフトバック式の保存容器を作る事ができる。さらに必要に応じて、支持用の穴や切り込み部、さらにはシート状物等の挿入ガイド機構を適当な時期に形成することができる。ここで、容器下部の突出部に設ける切り込み部は、フィルムの成形時に延伸方向が横手方向（＝切る方向）となるようにして製造しておくことで、切る方向の指向性が製造時に付与されるため、該切り込み部から極めて簡単に切るとる事ができる。
【００６９】

BACKGROUND OF THE INVENTION
The present invention relates to a novel soft-back enteral nutrient storage container. More specifically, a tube for enteral nutrition supply (enteral for transnasal or percutaneous use) in which an enteral nutrient such as a concentrated nutrient other than digested or semi-digested or liquid food is inserted into the subject. (Nutrition catheter), and if necessary, soft back used when replenishing through a nutrition drip set (connecting member to enteral nutrient storage container, connection rubber, drip tube, infusion set with roller clamp, etc.) The present invention relates to an enteral nutrient storage container of the formula.
[0002]
[Prior art]
At present, enteral nutrition supplementary tubes (enteral feeding catheters used nasally or percutaneously) for inserting enteral nutrients such as concentrated nutrients and liquid foods other than digestive and semi-digested forms into the subject. ) In addition, if necessary, enteral intestine used when replenishing through an infusion set (such as a connecting member to an enteral nutrient storage container, connection rubber, infusion tube, infusion set having a roller clamp, etc.) As a typical nutrient storage container, an upper open-type container for concentrated liquid foods with a spout is used. In the container for the concentrated liquid food with spout, the symptoms of each individual subject such as a nasal enteral feeding catheter through an extension tube joined to the liquid food outlet provided at the bottom of the container The selected catheter is inserted while monitoring the X-ray sensing part provided at the distal end of the catheter from the nose or mouth of the subject to the stomach, and a plurality of catheters provided near the distal end of the catheter are inserted. The liquid food is poured into the stomach from the hole. As a method of handling concentrated liquid foods using this upper open type specially prepared liquid food container with a spout, in order to prevent nosocomial infections, (1) concentrated (high nutrition) liquid food prepared 30 minutes before serving each meal is served. Dispense into sterilized container for concentrated liquid food with spout. {Circle around (2)} The distributed concentrated liquid food becomes a good medium for bacteria, so that the injection starts immediately. Wash your fingers to prevent contamination. (3) If not injected all at once, the remaining amount is immediately sealed and kept cool. Avoid leaving at room temperature. (4) When using the remaining amount, inject it at a suitable temperature in the microwave in the ward. (5) Return the dedicated cup after pouring to the lower car. Do not leave them in hospital rooms. (6) Enteral nutritional products are prepared and used in each ward, but this is also a hotbed of bacterial contamination, and handling is necessary. (7) The upper open type dedicated liquid food container with pouring spout is used after sterilization without additional administration once injection (amount required for the subject) is completed. The disinfection method uses 80-fold Milton solution or 50-fold Tego 51 solution, expelling air so that the inside is also disinfected, and leaving it on for 1 hour or more. The concentrated liquid food container is made of a hard resin molded product so that it can be sterilized and reused.
[0003]
For the purpose of preventing nosocomial infection, a lid that fits into the spout is detachably attached to the spout of the container for the concentrated liquid food with spout. Then, when dispensing a predetermined volume of concentrated liquid food according to the medical condition of the subject and after replenishing the concentrated liquid food, water is replenished to the subject (in addition, the concentrated liquid food remaining inside the container). The pour spout is in a closed state with the lid attached thereto, except when the drinking water is poured from the pour spout for the purpose of diluting and completely replenishing the subject.
[0004]
However, in such a container for concentrated liquid food with a spout that is open at the top, when pouring concentrated liquid food or drinking water into the liquid food container, a nurse or the like removed the lid and adjusted it to a container such as a dedicated cup. It is necessary to inject the concentrated liquid food or drinking water while paying attention to the scale attached to the dedicated container for the concentrated liquid food so that it becomes a required amount according to the doctor's prescription. For this reason, during the injection (dispensing) operation, foreign substances and bacteria in the air inevitably enter, so that the sterilized state in the apparatus cannot be maintained, and the opportunity for injection of bacteria increases due to contamination from the spout. In addition, such operations have to be performed manually by nurses and the like, and it is necessary to disinfect hands and wear gloves and masks carefully every time, which places a heavy burden on nurses and the like. In addition, liquid foods and drinking water poured into containers for concentrated liquid foods must be adjusted each time, which places a heavy burden on cooks and other items, and increases costs and increases medical expenses for patients. It was.
[0005]
Therefore, a container that can be stored in a retort so as to prevent nosocomial infection and contamination of foreign substances due to the invasion of bacteria into a container for concentrated liquid foods and to be able to store enteral nutrients by sterilization in advance, and is not opened at the outlet. Soft bag type enteral nutrient storage containers that have an unopened guarantee structure so that opening can be guaranteed have come to be used.
[0006]
In such a conventional soft-back enteral nutrient storage container, a predetermined amount of enteral nutrient is sealed and then sterilized at 121 ° C. for 30 minutes. Further, the enteral nutrient removal member made of hard resin having an enteral nutrient outlet attached to the lower part of the enteral nutrient storage container body is in a sterile state, and the contents of the contents are aseptic. Cap (unopened proof structure) for certifying correctness, safety, etc. is attached, and when using, the cap is detached and opened, and a connecting tube is connected to this to guarantee a sterile system It is something to try.
[0007]
However, in order to supply water, it was necessary to cut the upper part of the soft-bag type enteral nutrient storage container with sterilized scissors or the like and pour drinking water from the cut end with an appropriate injector. Therefore, once the upper part of the enteral nutrient storage container is cut, the cut end remains open, and there are many opportunities for invasion of bacteria from the open part, and there is still a possibility of nosocomial infection or contamination with foreign substances. is the current situation.
[0008]
Also, the enteral nutrient removal member made of hard resin having the enteral nutrient outlet is usually attached to the enteral nutrient storage container body made of soft resin by fusion bonding with a heat seal. ing. Compared to the seal part at the outer peripheral edge of the main body, it is difficult to obtain a sufficient adhesive strength with this dissimilar material heat seal, and the contents are sealed and sterilized, and then transported and handled. In addition, since an external load (especially sterilization treatment) is applied, a sufficient sealing state is not maintained at the bonding portion between the enteral nutrient removal member and the enteral nutrient storage container body, and the contents are bonded. There was a problem of leaking from the part.
[0009]
[Problems to be solved by the invention]
Therefore, in view of the above problems, the object of the present invention is to prevent foreign substances and bacteria from entering even after rehydration in a soft-bag type enteral nutrient storage container, and also to prevent leakage of contents. A soft-back enteral nutrient storage container that does not occur is provided.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the present inventors have conducted intensive studies on a soft-back enteral nutrient storage container. As a result, by providing a double sealing structure on the top, foreign substances and bacteria can be removed even after rehydration. Invasion can be effectively prevented, so that nosocomial infections can be prevented, and by forming an outlet using a part of the enteral nutrient storage container body, there is no variation in strength when sealing, and there is a certain amount Since adhesive strength can be ensured, it is possible to obtain an enteral nutrient storage container that does not cause any liquid leakage within the range of the planned external load (for example, the amount required by JIS).

DETAILED DESCRIPTION OF THE INVENTION
The soft bag type enteral nutrient storage container according to the present invention has a first sealing part for retort storage and a second sealing part for preventing invasion of foreign substances and bacteria when used in the upper part of the main body. A protrusion having an outlet of an unused guarantee structure is formed in the lower part.
[0036]
Embodiments of the present invention will be described below in detail with reference to the drawings.
[0037]
FIG. 1 is a schematic view showing a typical embodiment of the soft-bag enteral nutrient storage container of the present invention.
[0038]
As shown in FIG. 1, the soft-back enteral nutrient storage container 101 of the present embodiment includes a first sealing portion 103 for storing retort at the top of the main body and a first sealing portion 103 for preventing invasion of foreign matter and bacteria when used. Two sealing portions 105 are formed, and a protruding portion 107 having an outlet of an unused guarantee structure (including an opening structure) is formed at the lower part of the main body.
[0039]
An upper cut portion 109 is provided between the first sealing portion 103 and the second sealing portion 105. As a result, the second sealing portion 105 can be cut in parallel along the broken line shown in the drawing, and the upper first sealing portion 103 can be removed.
[0040]
The first sealing part 103 for retort storage on the upper part of the main body is a first seal for preserving retort having a sealing structure in which the whole peripheral part of the main body including the upper part of the main body is fused and bonded by, for example, heat sealing or high frequency sealing. A stop portion 103 and a peripheral sealing portion 111 for retort preservation are formed over the entire peripheral portion communicating with the stop portion 103. Further, of the peripheral sealing portion 111 for retort storage, the axis of the sealing portion 111 which is the upper portion of the container main body and is not provided with the double sealing portions 103 and 105, or the vicinity thereof, It is desirable that a hole 112 for suspending and supporting the enteric nutrient storage container 101 by a hook or the like is provided. That is, the double sealing portions 103 and 105 may be provided over the entire upper end of the container body. Rather, the supporting hole 112 is limited to a range where water can be easily injected. It is also excellent in that it can be formed and is functional, and it can minimize the invasion of foreign substances and bacteria when opened.
[0041]
Further, the second sealing portion 105 according to the present embodiment is a zipper-type seal structure that can be freely opened and closed (a zipper-type seal structure that can be freely opened and closed is used in a food storage bag “ziplock” (registered trademark) with a zipper. A structure similar to the above can be exemplified. By providing the second sealing portion 105, the enteral nutrient, which is the contents in the main body 111, is taken out from the outlet, for example, through a nutrient drip set (infusion set) or enteral feeding tube (catheter). Conventionally, the upper part of the soft-bag enteral nutrient storage container was cut and water was injected, but in this embodiment, as described above, along the broken line shown in the figure. The second sealing portion 105 is cut in parallel, the upper first sealing portion 103 is removed, the second sealing portion 105 is opened, and necessary water is injected from here. After the injection, the zipper The second sealing part 105 can be easily and quickly closed with a finger, and it can be seen that it is sealed with the touch of the fingertips, so you can never forget to close it and prevent the invasion of foreign substances and bacteria. is there. Note that the container (bag) having a zipper-type seal structure that can be freely opened and closed, which is the second sealing portion 105 according to the present embodiment, is a predetermined position of a take-up roll that stretches and winds the film in the film forming step. It is possible to form a film having a convex portion by providing a groove having an appropriate size, and similarly, a film having a concave portion corresponding to the convex portion can be formed. A container (bag) having a desired openable and closable zipper-type seal structure can be produced by punching and melting and bonding the peripheral portion with a heat seal. In addition, as described above, the main body portion and the upper portion of the main body having the openable / closable zipper-type seal structure are separately manufactured without manufacturing a container (bag) having a zipper-type seal structure that can be integrally opened and closed. Then, a desired container (bag) may be manufactured by fusion bonding with heat or high frequency afterwards and integrating them. At this time, directing in the cutting direction (direction indicated by a broken line in FIG. 1) is provided at the time of manufacture from the cut portion by making the drawing direction to be the longitudinal direction of the zipper. It can be easily cut (note that this can also be done in the cut portion provided in the protrusion at the lower part of the main body, which will be described later).
[0042]
In the enteral nutrient storage container of the present invention, the production method is not limited at all, and it goes without saying that conventionally known production techniques can be appropriately combined.
[0043]
In the present invention, in addition to the above-described embodiment, the intended purpose can be achieved by making the second sealing portion into another embodiment as shown in FIG.
[0044]
That is, as shown in FIG. 2, the second sealing portion 205 as another embodiment of the present invention has an elastic base piece 207 whose one end is bonded and supported to the nutrient storage container main body 202 by, for example, heat fusion. And a valve body portion 209 provided at the tip thereof to prevent the falling bacteria and foreign matter from entering. As shown by the broken line in FIG. 2, the valve body part 209 can be lifted up starting from the elastic base piece 207, and when released, the original state (state of the valve body part 209 shown by the solid line in FIG. 2) Return to. Therefore, after cutting off the first sealing portion 203 sealed so as to be able to preserve the retort fused by heat or high-frequency seal or the like, the valve body portion 209 is lifted and water is injected, and then the original state By returning to (2), it is possible to seal (prevent) invasion of foreign matter and bacteria (particularly, ingress of falling bacteria and foreign matter).
[0045]
In the present invention, the double sealing portion provided in the upper part is not limited to the one shown in the above embodiment, and after taking out the contents enclosed in the nutrient storage container from the outlet, After cutting between the first sealing portion and the second sealing portion, opening the second sealing portion on the inner side and pouring water, then closing the second sealing portion and intruding foreign matter or bacteria As long as it is formed so as to be able to prevent this, there is no particular limitation, and a conventionally known sealing structure can be appropriately selected and used.
[0046]
Next, as the unopened guarantee structure of the outlet formed in the protruding portion 107, the outer peripheral edge portion 113 of the protruding portion 107 is sealed, and the container body 102 side is closer to the tip seal portion 115 of the protruding portion 107. It is configured by a structure in which a lower notch 117 is provided in the side seal fusion part. That is, by cutting (opening) the lower notch 117 along the broken line shown in the protruding part 107 in FIG. 1, an outlet (a cut made at the position of the broken line) can be formed in the protruding part 107. it can. Therefore, when unopened, no outlet (cut) is formed, and the safety of the contents is guaranteed. On the other hand, after the tearing, the unsealed portion cannot be closed and returned to its original state, and the unusability of the unopened contents is also guaranteed.
[0047]
Furthermore, in the present invention, an insertion guide mechanism, particularly an opening for opening the connecting portion for facilitating introduction (insertion) of a connecting member outside the system into the opening (opening formed at the time of opening) is provided at the protruding portion. It is desirable that a mechanism is provided for this. In this embodiment, as a mechanism for opening the outlet, as shown in FIGS. 1A and 1B (enlarged cross-sectional view along the line AA ′ in FIG. 1), The protrusion 107 on the main body 102 side of 117 has at least one protrusion, preferably 2 to 5 protrusions (four are illustrated in FIG. 1) so as to extend in a plane perpendicular to the axis L of the protrusion 107. A portion (or recess) 119 is formed. By providing such a structure, when the cut (= open) state is cut along the broken line shown in the protruding portion 107, the outlet (cut) is closed as shown in FIG. In addition, by pressing with the thumb and forefinger in the direction of the arrow shown in the cross-sectional enlarged view along the line AA ′ in FIG. As shown in FIG. 1D, the outlet (cut) can be in an open state without being bent as a whole as in (E). Furthermore, in the present invention, a convex portion (or a concave portion) can be formed so as to extend in-plane in parallel to the axis L of the protrusion 107, but it extends in a plane orthogonal to the axis L of the protrusion 107. By forming the convex portion (or concave portion) as described above, there is an effect of making it difficult for the content liquid to flow out when a connection member outside the system is introduced. ) Serves as a guide, and has the advantage of tearing along the convex part (or concave part).
[0048]
Moreover, you may make an uneven | corrugated shape or a taper so that it may be hard to remove | exclude in the enteral nutrient solution flow path of a protrusion part after introduce | transducing (inserting) the connection member outside a system. That is, as shown in FIG. 6, for example, as shown in FIG. 6, many off-system connecting members that are currently on the market have (1) a substantially tapered cylindrical tip portion of the protruding portion 607 of the enteral nutrient storage container. As shown in FIG. 7, the connection member 620 outside the system that is cut obliquely so as to be easily introduced into the take-out port (cut), and (2) a straight cylindrical tip portion that is not particularly provided with a taper, There is a connection member 720 outside the system which is cut obliquely so as to be easily introduced into the outlet (cut) of the protruding portion 707 of the enteric nutrient storage container. Therefore, in the protruding portion of the enteral nutrient storage container corresponding to such a connecting member outside the system, the inner peripheral surface of the enteral nutrient channel of the protruding portion and the outer peripheral surface of the connecting member outside the system serve as a contact surface. For example, as shown in FIG. 6, the liquid can be prevented from leaking without detaching the connection member outside the system from the protrusion by using the force that the projection part pushes the connection member outside the system. As shown in FIG. 7, (1) the shape of the protrusion 607 (particularly the enteral nutrient channel) when the connection member 620 outside the system is introduced is a substantially reverse tapered cylindrical shape, (2) The shape of the protrusion 707 (particularly the enteral nutrient channel) when the connection member 720 outside the system is introduced is a straight columnar shape without a taper.
[0049]
Furthermore, in the present invention, as shown in FIG. 8, a convex portion 819 (or a concave portion) can be formed so as to extend in the plane in parallel with the axis L of the projecting portion 807. As shown in FIGS. 6 and 7, the convex portion serving as a guide when tearing from 817 is not provided in parallel to the tear line, so that it is difficult for force to be applied in parallel to the tear line when tearing, rather the convex portion (or concave portion). When 819 is torn, it acts as a guide and is torn in parallel with the convex part (or concave part) 819, and it does not become a clean cut, so liquid leakage occurs, and if it is severe, The tear may reach the main body and become unusable, and it is necessary to carefully cut it off using scissors that have been sterilized. Further, when the outside connection site 820 is introduced into the protrusion 807 of the enteral nutrient storage container, as shown in FIG. 8C, the contact surface between the protrusion 807 and the outside connection site 820 is formed. Since the gap a is formed by the convex portion 819, there is a risk that enteral nutrient and water leak.
[0050]
In addition, the insertion guide mechanism of the present invention, in particular, the mechanism for opening the outlet (opening mechanism) is not limited to the above-described embodiment. For example, the convex portion (or concave portion) shown in FIG. Instead of forming, at least one heat application unit or high-frequency application unit may be formed on the projecting portion on the main body side of the cut portion so as to extend in a plane perpendicular to the axis of the projecting portion. Also in this case, the heat application unit or the high frequency application unit is thermoset or thermally cross-linked to have a different material strength, and can function in the same manner as the convex portion (or concave portion). Similarly, as shown in FIGS. 3 (A) to 3 (C), the material strength can be changed by providing a protrusion 307 closer to the main body than the lower notch 317 and a surface orthogonal to the axis L of the protrusion 307. At least one strip-shaped sheet 321 may be circumscribed (or inscribed) so as to extend inward. Preferably, the central portion 323 of the sheet-like material 321 is thinned and both end portions 325 are thickened, and the sheet-like material 321 is pushed in the direction indicated by the arrow in FIG. The state can be remarkably generated. Furthermore, as a mechanism for opening the outlet (opening mechanism), as shown in FIG. 4, the opening member 429 may be held in the enteral nutrient channel portion 427 of the protruding portion 407. The opening member 429 in this case is not particularly limited as long as it is in the protruding portion 407 until the connection member outside the system is introduced, and can maintain the open state. ), (C), and (D), an opening member 429 having a shape in which at least a part thereof is inscribed in the enteral nutrient channel portion 427 (preferably the entire peripheral surface portion is in close contact) is provided. Specifically, as shown in FIG. 4 (A), a hollow cylindrical (hollow pipe) shaped opening member, and as shown in FIG. 4 (C), a solid substantially spherical shape. Alternatively, an opening member having a rugby ball shape, an opening member having a solid cylindrical inverted truncated cone shape (inverted tapered inverted truncated cone shape) as shown in FIG. 4D, or the like can be used. . As shown in FIGS. 4A and 4B, the opening member 429 is a hollow one such as a columnar shape, and the protrusion 407 (for example, a protrusion is provided in the flow path portion). The hollow part can also be used as an enteral nutrient channel part. In this case, as shown in FIG. 4A, it is necessary to use a connecting member 420 having an outer diameter corresponding to the inner diameter of the hollow portion. On the other hand, as shown in FIGS. 4C and 4D, in the case of a solid cylindrical pipe or a solid spherical object, it may be fixed or connected outside the system without being fixed. When the member 420 is introduced, it is struck by the connecting member 420, disengages from the enteral nutrient channel portion 427 of the protrusion 407, and is pushed out to the main body side of the enteral nutrient storage container. In this case, the opening member 429 may have a specific gravity lighter than that of the enteral nutrient so as not to block the enteral nutrient channel, and may be lifted. And, as shown in (D), the opening member 429 is reverse-tapered so that the diameter increases from the protruding portion side toward the storage container body side at the upper part of the enteral nutrient channel portion 427 installed when not opened. And the opening member 429 may not be lowered to the protruding portion side. It should be noted that the mechanism for opening the outlet in the present invention is not limited to the one described above, and it goes without saying that a conventionally known opening mechanism can be appropriately employed.
[0051]
In addition, the insertion guide mechanism of the present invention is another embodiment other than the structure for opening the outlet, for example, as shown in FIG. ) So that the front end 528 of a strip-like sheet-like material 527 (for example, made of polyethylene terephthalate (PET)) comes out from the outlet (cut). In addition, a part of the sheet-like material 527 may be fixed to the inner surface of the protrusion 507 on the main body side with respect to the lower notch 517 so as to extend in the axial direction of the protrusion 507. In this case, the front end portion 528 of the sheet-like material 527 serves as a guide, and the connecting member outside the system can be smoothly inserted along this. It should be noted that the insertion guide mechanism in the present invention is not limited to the one described above, and it goes without saying that a conventionally known insertion guide mechanism can be appropriately employed.
[0052]
Further, in the insertion guide mechanism on the container side of the present invention, as another embodiment of the structure for opening the outlet, for example, a rib is formed on the inner surface of the projecting portion on the main body side with respect to the cut portion. May be. In this case, in addition to the insertion guide function, when the connection member outside the system is introduced, the connection member outside the system can be held by the rib and can be surely sealed. Such ribs (protruding portions) and the concavo-convex portions shown in FIG. 1 may be formed integrally with the container main body sheet. However, the container main body is affixed to a sheet material having a protruding portion or concavo-convex shape on one side of the sheet. After the two sheet materials to be produced are bonded to each other, the container body sheet material may be bonded by fusion or the like.
[0053]
Moreover, it is desirable to reinforce the peripheral sealing portion extending from the lower portion of the container main body to the projecting portion among the peripheral sealing portions of the container main body. This is because the storage container is pulled due to movement of the subject during use, etc., and the shape tends to change, such as twisting of the part, thereby narrowing or closing the outlet. Because there is a shit that can happen.
[0054]
In addition, the enteral nutrient storage container of the present invention is characterized in that the lateral width of the protruding portion including the take-out port is widely formed so as to prevent twisting due to heat sterilization.
[0055]
FIG. 9 is a typical one in which the width of the protruding portion including the outlet of the soft-bag enteral nutrient storage container of the present invention is wide so as to prevent twisting due to heat sterilization treatment. It is the schematic showing embodiment.
[0056]
As shown in FIG. 9 (a), the width of the protruding portion 907 including the outlet of the soft-bag enteral nutrient storage container 901 of this embodiment is wide so as to prevent twisting due to heat sterilization. Is formed. Specifically, the lateral width of the protruding portion 907 including the outlet is represented by the following formula:
2 ≦ y / x ≦ 6, preferably 3 ≦ y / x ≦ 5
(Here, x is the width of the protruding portion including the outlet as shown in FIG. 9 (a), and y is the width of the enteral nutrient storage container body as shown in FIG. 9 (a). It is desirable that it is formed so as to satisfy When 2> y / x in the above formula, there is no particular problem, but the connecting member to be connected to this is large and inconvenient to handle, and the outlet area at the time of connection becomes large, so that bacteria and the like enter. In addition, if the connecting member is removed, a large amount of contents will flow out, which is not preferable from the viewpoint of the safety of the subject. On the other hand, when y / x> 6 in the above formula, it is difficult to prevent twisting due to heat sterilization, and it is difficult to attach the connecting member, and after installation, the content leaks along the wrinkles caused by twisting. Since there are cases, it is not preferable.
[0057]
Furthermore, preferably, as shown in FIG. 9 (a), it is desirable that the peripheral sealing portion between the enteral nutrient storage container main body and the protruding portion be formed in a gentle slope shape, as shown in FIG. 9 (b). As shown in Fig. 5, it is easy to cause twisting due to heat sterilization if the lateral width is narrowed without forming such a slope. Therefore, the following formula
0.5 ≦ z / x ≦ 10,
Preferably, 0.7 ≦ z / x ≦ 5,
More preferably, 1 ≦ z / x ≦ 3
(Here, x is the width of the protrusion including the outlet as shown in FIG. 9 (a), and z is the enteral nutrient storage container body and the protrusion as shown in FIG. 9 (a). It is desirable that the peripheral sealing portion between the enteral nutrient storage container main body and the protruding portion is formed in a gentle slope shape so as to satisfy the above.
[0058]
Further, when the protruding portion 907 including the outlet of the enteral nutrient storage container 901 is formed widely as described above, a cut portion is provided in the side seal portion on the main body side than the tip seal portion of the protruding portion. It is not necessary to provide an insertion guide mechanism for making the structure easy to introduce a connection member outside the system. This is because the protrusion 907 is formed widely as described above, so that it can be easily opened and a connection member outside the system can be introduced (inserted).
[0059]
Next, when the protruding portion including the outlet of the enteral nutrient storage container 901 is widely formed as described above, it is desirable to use a connecting member corresponding to the protruding portion. In other words, one end of the corresponding connecting member has a structure that can be joined to the protruding portion including the widely formed outlet of the enteral nutrient storage container, and the other end of the connecting member is the tube for enteral nutrition supply or enteral It has a structure that can be connected to an enteral feeding catheter.
[0060]
FIG. 10 shows a typical embodiment of a connecting member corresponding to the case where the protrusion including the outlet of the soft bag type enteral nutrient storage container of the present invention is formed widely as described above. FIG.
[0061]
As shown in FIG. 10, the connecting member 11 of this embodiment has a shape in which two cylindrical bodies having different diameters are joined (connected). Of these, the cylindrical portion 13 having a large diameter is a side to be joined to the protruding portion including the outlet of the enteral nutrient storage container, and the distal end portion 15 on the cylindrical portion 13 side having the large diameter is connected to the opened outlet. It is desirable to have an insertion guide structure for easy introduction. In the insertion guide structure, the distal end portion 15 of the cylindrical portion 13 having a large diameter has an insertion opening 17 that is cut obliquely (cut into a shape obtained by obliquely breaking bamboo). In addition, there is a rib (uneven portion) 23, flange, etc. in the middle of the outer periphery of the cylindrical portion 13 with a large diameter so that it can be easily grasped when connecting, and the contents are prevented from leaking and falling off after connecting. An appropriate number may be provided, or the outer peripheral surface may be roughened. Further, the diameter of the distal end portion 15 on the side of the cylindrical portion 13 having a larger diameter may be gradually narrowed toward the distal end. This is because it can be quickly inserted into a more opened outlet. On the other hand, the cylindrical portion 19 having a small diameter is a side that can be connected to an enteral feeding tube or an enteral feeding catheter, and the distal end portion 21 is preferably narrowed so as to be easily inserted into such a tube. . In addition, in order to form a shape in which cylindrical portions having different diameters are joined (connected), it can be easily manufactured by molding. However, since the boundary portion of the cylindrical portions having different diameters is weak in strength and easily broken, The cylindrical portion having a small diameter may be thickened or may be provided with a slope to avoid stress concentration and be difficult to break.
[0062]
Further, the connecting member is preferably formed or surface-treated with a material capable of preventing the content from bleeding from the connecting portion with the outlet of the enteral nutrient storage container. Here, as a material capable of preventing the content from bleeding from the connection portion with the outlet of the enteral nutrient storage container, a hydrophobic resin may be used. For example, polyethylene terephthalate, tetrafluoroethylene resin may be used. (Teflon: trade name of DuPont, USA), ABS resin (durable thermoplastic resin obtained by copolymerization or blending of acrylonitrile, butadiene, styrene) and the like. Further, when such a hydrophobic resin is subjected to a surface treatment, a hydrophilic resin may be used for the base material, and the surface may be subjected to a water-repellent treatment (for example, a surface coating treatment with a hydrophilic resin).
[0063]
Next, as another embodiment of the connecting member for the enteral nutrient storage container of the present invention, insertion for easy introduction into the outlet after opening the soft-back enteral nutrient storage container described above A guide structure and a drop prevention structure for preventing the connecting member from dropping out of the outlet after insertion are provided.
[0064]
The insertion guide structure portion on the connecting member side for the enteral nutrient storage container of the present invention is not particularly limited, and a conventionally known insertion guide structure can be appropriately used. It is desirable that the insertion portion has an elliptical cross-sectional shape that is flat to match the cross-sectional shape of the outlet after opening. This is because the outlet after opening the container of the present invention is formed integrally with the container body without using a threaded cap or the like as described above, so that the cross-sectional shape of the outlet is flat. It has a shape. Therefore, if the cross-sectional shape of the insertion part is circular as in the case of an existing enteral nutrient storage container, the compatibility will deteriorate and the airtightness cannot be sufficiently maintained. Problems such as leakage of the contents from both ends of the outlet or dropping of the connecting member occur. Therefore, it is desirable to form the cross-sectional shape of the insertion part of the connection member into a flat cross-sectional elliptical shape. However, as for the insertion part by the side connected to the tube for enteral-nutrition supply among connection members, it is desirable that the cross-sectional shape is circular shape similarly to the past.
[0065]
In addition, the drop-off prevention structure portion on the side of the connecting member for the enteral nutrient storage container of the present invention is not particularly limited, and a conventionally known drop-off prevention structure can be appropriately used. It is desirable that the connecting member is a headband-shaped projecting portion provided on the outer periphery of the insertion portion to the outlet after opening the container. In particular, as shown in FIG. 1, in the case where an uneven shape is provided on the inner surface portion of the protruding portion on the container side, it is desirable that the protruding portion shape conforms to the uneven shape.
[0066]
In addition, regarding the material that can be used for the soft-bag enteral nutrient storage container of the present invention, it can be retorted, so that it can be stored for a long period of time even under severe conditions of temperature difference throughout the seasons. It is not particularly limited as long as it is a material that has excellent characteristics such as heat resistance, cold resistance, and thermal variability, is capable of high-frequency sealing and heat sealing, and is provided with workability and directivity in the cutting direction. It can be used by appropriately selecting from materials developed for conventionally known retort bags, such as aluminum or SiO.₂Vapor deposited polyester-nylon-CCP three-layer structure, nylon-aluminum or SiO₂A vapor-deposited polyester-nylon-CCP four-layer structure can be exemplified.
[0067]
In addition, the soft-bag type enteral nutrient storage container of the present invention is a concentrated nutrient or liquid food other than digested and semi-digested foods (these nutrients and liquid food contain drugs such as antibiotics). Enteric nutrients such as, and drinking water (and may be obtained by dissolving a suitable water-soluble vitamin C or other nutrients such as vitamin C or antibiotics). Enteral feeding tube (enteral feeding catheter used transnasally or percutaneously) through which the aqueous solution is passed through the subject in sequence, and if necessary, a nutritional drip set (enteral nutrient storage container For example, an infusion set having a connecting member, a connecting rubber, a drip tube, a roller clamp, etc.). In addition, as in the case of a conventional container for concentrated liquid food with a spout with an open top, it is possible to store it safely for a long period of time so that it is not necessary to adjust enteral nutrients each time. In such a case, it is possible to suitably cope with a case where it becomes necessary to appropriately replenish enteral nutrients after receiving advanced medical care at home or a nursing facility due to future aging.
[0068]
The manufacturing method of the soft-bag enteral nutrient storage container of the present invention is not limited at all, and can be manufactured by appropriately using conventionally known manufacturing techniques for soft-back storage containers. For example, two films are stacked and punched with a suitable mold, and the peripheral sealing portion (the container is turned sideways to inject the contents into the first sealing portion and the second sealing portion). In this state, it is desirable to leave unfused portions at the positions on the upper side). After the portions to be melted and bonded by heat or high frequency, the first sealing portion is placed in a state where the container is turned sideways. And put the contents from the unfused portion into the second sealing portion, melt and bond the unfused portion left to inject the contents with heat or high frequency, and then sterilize by heating. Thus, the soft-back type storage container of the present invention can be made. Furthermore, if necessary, a support hole, a cut portion, and an insertion guide mechanism such as a sheet-like material can be formed at an appropriate time. Here, the cut portion provided in the protruding portion at the bottom of the container is manufactured so that the drawing direction is the transverse direction (= cutting direction) during film formation, so that directivity in the cutting direction is imparted during manufacturing. Therefore, it can be cut very easily from the cut portion.
