Description

この発明は、収容部からの排出流路が、可撓性容器本体の内部の閉塞部により開口可能に閉塞されていて、使用時に可撓性容器本体の外側からこの閉塞部を開口させることにより、収容物を排出できる可撓性容器及びこの可撓性容器を用いた薬剤入り可撓性容器に関する。 According to the present invention, the discharge flow path from the housing portion is closed so as to be openable by the closed portion inside the flexible container body, and the closed portion is opened from the outside of the flexible container body at the time of use. The present invention relates to a flexible container that can discharge a stored item, and a flexible container containing a medicine using the flexible container .

内視鏡検査を行う際、かん子口から止血剤を投与することが従来より行われており、近年になって、麻酔剤等の他の薬剤をかん子口から投与することも提案されている。このような薬剤の投与には、一般にシリンジが使用されており、予め薬剤をシリンジに収容しておき、シリンジの先端をかん子口に嵌合させて排出することにより行われる。   When performing endoscopy, it has been conventionally practiced to administer a hemostatic agent from the cannula opening, and in recent years it has also been proposed to administer other drugs such as anesthetics from the cannula opening. In general, a syringe is used to administer such a drug, and the drug is stored in advance in a syringe, and the tip of the syringe is fitted into the cannula port and discharged.

シリンジを用いる場合、通常の注射用薬剤が収容されたシリンジと区別して取り扱う必要があり、過誤によりかん子口から投与される薬剤を注射用薬剤として使用されないように注意する必要がある。
下記特許文献1では、このような過誤を確実に防止するために、蛇腹構造等、シリンジとは明確に異なる形態を有する可撓性容器に止血用薬剤を収容したものが提案されている。
When a syringe is used, it is necessary to handle it separately from a syringe containing a normal injection drug, and care must be taken not to use a drug administered from the mouth opening due to an error.
In Patent Document 1 described below, in order to reliably prevent such an error, a hemostatic drug or the like stored in a flexible container having a form clearly different from a syringe, such as a bellows structure, is proposed.

また、従来より、各種の物質を収容するために変形可能な樹脂製の可撓性容器が多数使用されている。その可撓性容器としては、排出部に硬質の成形体を用いたものも多数知られている。   Conventionally, many plastic flexible containers that can be deformed to accommodate various substances have been used. As the flexible container, many containers using a hard molded body for the discharge part are also known.

例えば、下記特許文献2には、バッグ本体に瓶針及びそのための流路とを配置し、流路とバッグ本体内部との連通を阻止する封止部及び破断部をバッグ本体内に設けた混注用輸液バッグが提案されている。
この混注用輸液バッグを使用するには、瓶針を他の容器に刺通した後、バッグ本体内の破断部をバッグ本体の外側から作業者が破断して開口させ、次に、バック本体を圧縮することにより、内部の輸液を瓶針を経由して他の容器に排出させて使用することができる。
For example, in the following Patent Document 2, a mixed injection in which a bottle needle and a flow path therefor are arranged in a bag body, and a sealing portion and a break portion that prevent communication between the flow path and the inside of the bag body are provided in the bag body. Infusion bags have been proposed.
In order to use this infusion bag, the bottle needle is pierced into another container, the operator breaks and opens the broken part in the bag body from the outside of the bag body, and then the bag body is opened. By compressing, the infusion solution inside can be used after being discharged into another container via a bottle needle.

ここでは、導出口から封止部までが単一の成形体であるため、樹脂シートを剥離可能に溶着するものなどに比べ、連通時の破断部の破断荷重を安定させ易く、また部品点数を抑えて安価に製造することが可能である。   Here, since the lead-out port to the sealing part is a single molded body, it is easier to stabilize the rupture load of the rupture part at the time of communication and the number of parts compared to the case where the resin sheet is welded to be peelable. It can be manufactured at a low cost.

しかしながら、閉塞部及び破断部が単にバック本体内に直線的に配置して突出しているだけであるため、使用時には、使用者が両手で排出部の瓶針側と閉塞部側とをバック本体の外側から把持し、バック本体を横にした状態で破断部を屈曲させて破断する開口操作を行う必要があり、その後に、バック本体を持ち替えてから、容器壁を圧迫して内部の輸液を瓶針から排出させて排出操作を行わなければならない。そのため、異なる2つの操作を順次行わなければならず、使用時の操作性が悪かった。   However, since the closed portion and the rupture portion are simply arranged linearly in the back body and project, the user can use both hands to connect the bottle needle side and the closed portion side of the discharge portion with both hands. It is necessary to perform an opening operation to bend and break by breaking the rupture part while holding the back body sideways while holding the bag from the outside, and then holding the back body and pressing the container wall to bottle the infusion solution inside It must be ejected from the needle. Therefore, two different operations have to be performed sequentially, and the operability during use is poor.

しかも、一般的に医療で用いられるバッグの材質は、ポリエチレン、ポリプロピレン等であり、ガス透過性が高い為、長期間保存されると、バック内部と外部の水蒸気分圧差に起因し、バッグ外部から内部へエアーが透過して、バッグが膨らむ現象を生じ、使用時に破断部を破断させる際、閉塞部を把持することが著しく困難になって、より操作性が悪化することがあった。   Moreover, the materials of bags generally used in medicine are polyethylene, polypropylene, etc., and because of high gas permeability, when stored for a long period of time, due to the difference in water vapor partial pressure between the inside and outside of the bag, When air penetrates into the interior and the bag swells, the rupture portion is broken during use, making it difficult to grip the closed portion, and the operability may be further deteriorated.

下記特許文献3には、可撓性容器の本体部に、流通路を有する導出用突部が設けられて先端部が薄膜部で密封されると共に、薄膜部を刺通可能な針状部を有する開封アダプタが導出用突部に摺動可能に装着された液体容器が提案されている。
この液体容器では、使用時に開封アダプタの小径部を他の容器等の開口に挿入して、導出用突部に対して開封アダプタを摺動させることにより、薄膜部を針状部で刺通して開封すると共に内容液を排出させて使用することができる。
In Patent Document 3 below, a lead-out projection having a flow passage is provided in the main body of the flexible container, the tip is sealed with a thin film, and a needle-shaped part that can pierce the thin film is provided. There has been proposed a liquid container in which an unsealing adapter having a sliding adapter is slidably attached to a lead-out protrusion.
In this liquid container, the small diameter portion of the unsealing adapter is inserted into an opening of another container or the like during use, and the unsealing adapter is slid with respect to the protruding protrusion, whereby the thin film portion is pierced by the needle-shaped portion and unsealed. In addition, the content liquid can be discharged and used.

ここでは、可撓性容器と、導出用突部及び開封アダプタとが同軸上に配置されているため、開封アダプタを挿入した後、針状部で薄膜部を刺通して連続的に可撓性容器の収容液を排出させる操作が可能である。   Here, since the flexible container, the lead-out protrusion and the unsealing adapter are arranged coaxially, after inserting the unsealing adapter, the needle-shaped portion is pierced through the thin film portion and continuously the flexible container. The operation of discharging the stored liquid is possible.

しかしながら、この液体容器では、可撓性容器の外に導出用突部が設けられている上に、この導出用突部に対して開封アダプタを摺動可能に配置しているため、必然的に連通部分が大きくなり、コンパクト化し難いという問題点があった。
しかも、複数の部品を組み合わせており、更に、摺動させるため、針状部の刺通荷重に対する開封アダプタの摺動荷重を調整したり、液漏れや内部の清浄度を維持する手段が必要になるなど、構成が複雑になり易いという問題点も有していた。
特願2004―2271号公報 特公平5―52748号公報 特開2001―187112号公報
However, in this liquid container, the lead-out protrusion is provided outside the flexible container, and the opening adapter is slidably disposed with respect to the lead-out protrusion. There was a problem that the communication part became large and it was difficult to make it compact.
In addition, a plurality of parts are combined, and in order to further slide, means for adjusting the sliding load of the unsealing adapter with respect to the piercing load of the needle-like part, and means for maintaining liquid leakage and internal cleanliness are necessary. For example, the configuration is likely to be complicated.
Japanese Patent Application No. 2004-2271 Japanese Patent Publication No. 5-52748 Japanese Patent Laid-Open No. 2001-187112

本願の請求項1に係る可撓性容器によれば、複数の操作突起が先端側を互いに離間させて可撓性容器本体の外側から相対変位可能に配置され、例えば、可撓性容器本体を外側から圧迫するなどにより複数の操作突起を相対変位させると、排出流路を閉塞する閉塞部が開口可能に構成されているので、可撓性容器本体と共に複数の操作突起を相対変位させることで、排出流路の収容室側の閉塞部を開口させることができ、排出流路の開口操作が容易である。しかも、開口操作後に収容室から収容物を排出させる排出操作も、収容室が設けられた可撓性容器本体を外側から圧迫して行うため、排出流路の開口操作から連続して収容物の排出操作を行うことができる。そのため、開口操作と排出操作とを別々に行う必要がなくて操作が単純であり、操作中の可撓性容器の持ちかえなどの手間も抑えることができ、使用時の操作性が良好である。
しかも、複数の操作突起を例えば圧迫することで排出流路を開口させるように構成するだけであるため構造を簡単にできると共に、その複数の操作突起が可撓性容器本体内に配置されるため小型化を図り易い。
According to the flexible container according to claim 1 of the present application, the plurality of operation protrusions are disposed so that the distal end sides are separated from each other and can be relatively displaced from the outside of the flexible container body. When the plurality of operation projections are relatively displaced by pressing from the outside or the like, the closing portion that closes the discharge channel is configured to be openable, so that the plurality of operation projections can be relatively displaced together with the flexible container body. The closure part of the discharge channel on the side of the storage chamber can be opened, and the opening operation of the discharge channel is easy. In addition, the discharge operation for discharging the stored material from the storage chamber after the opening operation is performed by pressing the flexible container body provided with the storage chamber from the outside. A discharge operation can be performed. Therefore, it is not necessary to perform the opening operation and the discharging operation separately, and the operation is simple, and it is possible to reduce the trouble of holding the flexible container during the operation, and the operability during use is good. .
In addition, the structure can be simplified because the discharge channel is simply opened by pressing the plurality of operation protrusions, for example, and the plurality of operation protrusions are disposed in the flexible container body. Easy to miniaturize.

特に、本願の請求項1に係る可撓性容器によれば、複数の操作突起が可撓性容器本体の排出部側の端部から他方側の端部へ延在する両縁部に沿って配置されているため、使用者が可撓性容器本体を片手で掴み、容器本体を一回圧迫することで(例えば、容器本体を一握りすることで)、容器を持ち替えることなく、閉塞部の開口と内容物の排出を略同時に行うことができる。このため、例えば医療現場等において、使用者が医療機器や移し替え容器を一方の手で保持している場合であっても、他方の手のみの一回の操作で閉塞部の開口と内容物の排出を略同時に行うことができる。これにより、従来にはない作業性に優れた可撓性容器を提供することができる。
また、樹脂製容器を長期間保存するなどにより、収容室内にエアーが充満して可撓性容器本体が膨張した場合であっても、複数の操作突起が可撓性容器本体の両縁部に沿って配置されているため、確実に排出操作を行うことができ、長期間保存時の使い勝手も確保し易い。
In particular, according to the flexible container according to claim 1 of the present application, the plurality of operation projections extend along both edges extending from the discharge portion side end portion of the flexible container body to the other end portion. Because it is arranged, the user can grasp the flexible container body with one hand and press the container body once (for example, by holding a handful of the container body). The opening and the contents can be discharged almost simultaneously. For this reason, for example, in a medical site, even if the user holds a medical device or a transfer container with one hand, the opening and contents of the blocking portion can be operated by one operation only for the other hand. Can be discharged almost simultaneously. Thereby, the flexible container excellent in workability | operativity which is not in the past can be provided.
Even when the container is filled with air and the flexible container body expands by storing the resin container for a long period of time, a plurality of operation projections are formed on both edges of the flexible container body. Since it is arranged along, it is possible to reliably perform the discharge operation, and it is easy to ensure the usability during long-term storage.

本願の請求項2に係る可撓性容器によれば、開口可能な閉塞部が複数の操作突起の相対変位により破断して開口される開口形成部であるので、閉塞部を排出部や複数の操作突起と一体に作製することができ、部品点数を少なくしてより構成を簡単にできる。   According to the flexible container according to claim 2 of the present application, the openable closing portion is an opening forming portion that is opened by being broken by the relative displacement of the plurality of operation protrusions. It can be manufactured integrally with the operation projection, and the configuration can be simplified by reducing the number of parts.

本願の請求項3に係る発明によれば、開口形成部が収容室と排出流路との間を仕切る閉塞部に形成された例えば括れ部のような脆弱部であるので、開口形成部の位置、大きさ、破断強度などを設定し易く、可撓性容器の品質を安定化し易い。   According to the invention according to claim 3 of the present application, since the opening forming portion is a weak portion such as a constricted portion formed in the closing portion that partitions between the storage chamber and the discharge channel, the position of the opening forming portion It is easy to set the size, breaking strength, etc., and to stabilize the quality of the flexible container.

本願の請求項又はに係る発明によれば、可撓性容器本体が排出部側の端部から他方側の端部に向けて拡幅する傾斜縁を有し、複数の操作突起の少なくとも一つが前記傾斜縁に沿って配置されているので、使用者の手の大きさに拘わらず、開口操作や排出操作を行い易い幅で使用者が可撓性容器を把持することができ、より使い勝手がよい。

以下、この発明の実施の形態について説明する。
[第1の実施の形態]
図1は、この発明の第1の実施の形態を示している。
図において、符号10は可撓性容器であり、内部に密封された収容室11が設けられた可撓性容器本体13と、可撓性容器本体13の一方の端部に液密に接続され、収容室11からの排出流路15が設けられた排出部17と、排出流路15の収容室11側を閉塞するように排出部17と一体に形成された閉塞部19と、この閉塞部19と一体に形成された操作突起部21とを備えている。尚、この実施の形態にあっては、後述するように、操作突起部21は、操作突起21a、21bから構成されている。
Embodiments of the present invention will be described below.
[First Embodiment]
FIG. 1 shows a first embodiment of the present invention.
In the figure, reference numeral 10 denotes a flexible container, which is liquid-tightly connected to a flexible container main body 13 provided with a sealed storage chamber 11 and one end of the flexible container main body 13. A discharge portion 17 provided with a discharge flow path 15 from the storage chamber 11, a closing portion 19 formed integrally with the discharge portion 17 so as to close the storage flow passage 15 on the side of the storage chamber 11, and the closed portion 19 and an operation projection 21 formed integrally. In this embodiment, as will be described later, the operation protrusion 21 is composed of operation protrusions 21a and 21b.

この可撓性容器10の収容室11は、20〜50cm程度の容積を有し、止血剤、麻酔剤等の薬剤、飲料等の食品などの収容物が、気体、液体、粉粒体、これらの混合物、分散物、或いはゲルなどの形態で収容されている。
特に、収容物としては、流体が好ましく、これらの流体としては、薬剤、溶解液、希釈液、細胞培養等の培地、食品類や化粧品類が例示できるが、収容物はこれらに限定されるものではなく、任意である。
この実施の形態では、内視鏡使用時に投与される、例えば、ペパーミントオイル、又はL−メントールを主成分とした薬剤が収容されている。薬剤の封入量は成人男性の一回の投与量相当となっている。
The storage chamber 11 of the flexible container 10 has a volume of about 20 to 50 cm 3 , and a container such as a hemostatic agent, a drug such as an anesthetic agent, and a food such as a drink contains gas, liquid, powder, These are contained in the form of a mixture, dispersion, or gel.
In particular, fluids are preferable as the contents, and examples of these fluids include drugs, dissolution liquids, diluents, mediums such as cell culture, foods and cosmetics, but the contents are limited to these. Rather, it is optional.
In this embodiment, for example, a medicine mainly composed of peppermint oil or L-menthol, which is administered when the endoscope is used, is accommodated. The amount of drug encapsulated is equivalent to a single dose for an adult male.

可撓性容器本体13は、使用者の握力により容易に変型可能な程度の可撓性を有する合成樹脂等の容器壁材料から形成されている。例えば、薬剤を収容する場合、医療用容器として使用可能なポリエチレン、ポリプロピレン、エチレン−酢酸ビニル共重合体、塩化ビニル、ポリエステル、ナイロン、環状ポリオレフィン等の熱可塑性樹脂を用いることができ、さらに、これらを組み合わせた積層シートとしても良い。また、食品用としては、上記材質のほか食品衛生法に適合する材料であればよい。   The flexible container main body 13 is formed from a container wall material such as a synthetic resin having such flexibility that it can be easily deformed by the gripping force of the user. For example, when containing a drug, thermoplastic resins such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer, vinyl chloride, polyester, nylon, and cyclic polyolefin that can be used as medical containers can be used. It is good also as a lamination sheet which combined. For food, any material that complies with the Food Sanitation Law in addition to the above materials may be used.

収容物として、ペパーミントオイル、L−メントール、脂溶性ビタミン等のように、エチレンやポリプロピレン等のオレフィン系樹脂に吸着されやすい物質が含まれる場合には、環状ポリオレフィン系樹脂を用いるのがよい。その場合、収容物と接する面に環状ポリオレフィン層がポリエチレンやポリプロピレン等のオレフィン系樹脂層に積層された多層構造の材料を用いるのが特に好適である。環状ポリオレフィンがポリエチレンやポリプロピレン等のオレフィン系樹脂に比べて可撓性を得にくいからである。   In the case where a substance that is easily adsorbed by an olefinic resin such as ethylene or polypropylene, such as peppermint oil, L-menthol, or a fat-soluble vitamin, is included as the contained material, a cyclic polyolefinic resin may be used. In that case, it is particularly preferable to use a multilayer structure material in which a cyclic polyolefin layer is laminated on an olefin-based resin layer such as polyethylene or polypropylene on the surface in contact with the container. This is because cyclic polyolefin is difficult to obtain flexibility as compared with olefinic resins such as polyethylene and polypropylene.

この可撓性容器本体13は、このような容器壁材料を成形及び/又は溶着することにより形成されており、左右両縁部13e間の幅が30〜60mm程度の扁平形状を有し、排出部17が配置された端部13a側から他方の端部13bに向けて拡幅する傾斜縁13cを、排出部17の左右両側に有している。   The flexible container body 13 is formed by molding and / or welding such a container wall material, has a flat shape with a width between the left and right edges 13e of about 30 to 60 mm, and is discharged. The discharge portion 17 has inclined edges 13c that widen from the end portion 13a side where the portion 17 is disposed toward the other end portion 13b.

排出部17は、可撓性容器本体13の最内層と同一の樹脂により成形された成形体からなり、可撓性容器本体13の収容室11に接して配置され、端部13aに溶着された基部17aと、この基部17aから外側に直線的に突出した導出口17bとを有している。排出流路15は、基部17a及び導出部17bを連続して貫通するように形成されている。   The discharge portion 17 is made of a molded body formed of the same resin as the innermost layer of the flexible container main body 13, and is disposed in contact with the storage chamber 11 of the flexible container main body 13 and welded to the end portion 13a. It has a base portion 17a and a lead-out port 17b that linearly protrudes outward from the base portion 17a. The discharge channel 15 is formed so as to penetrate the base portion 17a and the lead-out portion 17b continuously.

排出流路15の導出部17b側の端部15aには開口部15bが形成されて、タンパプルーフ用シール15dにより剥離可能に閉塞されている。排出流路15の収容室11側の端部15cは、排出部17及び操作突起部21と一体に形成された閉塞部19により完全に密封されている。閉塞部19は、収容室11内と排出流路15内との間を完全に仕切っている。   An opening 15b is formed at the end 15a of the discharge channel 15 on the lead-out portion 17b side, and is closed so as to be peeled off by a tamper-proof seal 15d. The end portion 15 c of the discharge flow channel 15 on the storage chamber 11 side is completely sealed by a closing portion 19 formed integrally with the discharge portion 17 and the operation projection portion 21. The blocking part 19 completely partitions the inside of the storage chamber 11 and the discharge channel 15.

この実施の形態では、閉塞部19の操作突起部21と排出部17との間の側面側の位置に、変形されることにより容易に破断可能な程度に局部的に薄肉化された、切り込み状の開口形成部としての括れ部23が形成されている。   In this embodiment, the cut portion is locally thinned to the extent that it can be easily broken by being deformed to the position on the side surface between the operation projection 21 and the discharge portion 17 of the closing portion 19. A constricted portion 23 is formed as an opening forming portion.

この括れ部23は、操作突起部21を構成する操作突起21a、21bが相対変位することにより破断可能に形成されており、1本の操作突起21aの排出部17側端部の全周にのみ形成されている。そのため、この可撓性容器10は、操作突起21aが操作突起21bに対して変位されることにより、括れ部23が破断して、排出流路15の収容室11側が開口されるように構成されている。   The constricted portion 23 is formed so that it can be broken by relative displacement of the operation projections 21a and 21b constituting the operation projection portion 21, and only on the entire circumference of the end portion on the discharge portion 17 side of one operation projection 21a. Is formed. Therefore, the flexible container 10 is configured such that when the operation protrusion 21a is displaced with respect to the operation protrusion 21b, the constricted portion 23 is broken, and the storage channel 11 side of the discharge channel 15 is opened. ing.

操作突起部21は、排出部17から収容室11側に向けて延出した複数の操作突起21a…から構成されており、可撓性容器本体13の一方の傾斜縁13c及び縁部13eに沿う一方の操作突起21aと、可撓性容器本体13の他方の傾斜縁13c及び縁部13eに沿う他方の操作突起21bとの一対からなる複数の操作突起21a、21bによる操作突起部21が形成されている。   The operation protrusion 21 is composed of a plurality of operation protrusions 21 a extending from the discharge portion 17 toward the storage chamber 11, and extends along one inclined edge 13 c and the edge 13 e of the flexible container body 13. An operation protrusion 21 is formed by a plurality of operation protrusions 21a and 21b, which are a pair of one operation protrusion 21a and the other operation protrusion 21b along the other inclined edge 13c and edge 13e of the flexible container body 13. ing.

この操作突起部21は、樹脂の破断や弾性により、一方の操作突起21aを他方の操作突起21bに対して近接する方向に相対変位させることが可能に構成されている。
尚、この実施の形態のみならず、本発明において、破断とは、一方の操作突起21aを他方の操作突起21bに対して近接する方向に相対変位させると、操作突起21aが括れ部23から完全に切離されて排出流路15の収容室11側が開口する場合や、一方の操作突起21aを他方の操作突起21bに対して近接する方向に相対変位させると、括れ部23の一部が破断して排出流路15の収容室11側が開口するが、操作突起21aは完全には切離されないで、操作突起21aが変位方向に折曲する場合等を含むことを意味している。
また、括れ部23に替えて、容易に破断が可能なように目視では確認困難な程度の切り込み等を入れた構成であってもよく、要はこの箇所を起点として一方の操作突起21aを他方の操作突起21bに対して近接する方向に相対変位ができ、これによって排出流路15の収容室11側が開口する構成であればよい。本発明においては、これらの構成を脆弱部と称する。
また、一対の操作突起21a、21bの間の角度θは20°〜120°、特に、40°〜80°とするのが好適である。良好な操作性を確保し易いからである。
The operation protrusion 21 is configured to be able to relatively displace one operation protrusion 21a in a direction approaching the other operation protrusion 21b by the breakage or elasticity of the resin.
Not only in this embodiment but also in the present invention, the term “break” means that when one operating projection 21a is relatively displaced in the direction approaching the other operating projection 21b, the operating projection 21a is completely removed from the constricted portion 23. When the housing 11 side of the discharge channel 15 is opened or when one operating projection 21a is relatively displaced in the direction approaching the other operating projection 21b, a part of the constricted portion 23 is broken. Thus, the storage channel 11 side of the discharge channel 15 is opened, but the operation protrusion 21a is not completely separated, which means that the operation protrusion 21a is bent in the displacement direction.
Further, instead of the constricted portion 23, a configuration in which a notch or the like that is difficult to visually confirm is provided so that it can be easily broken. In short, one operation protrusion 21a is used as a starting point from this point. Any configuration may be employed as long as it can be relatively displaced in the direction of approaching the operation projection 21b, and the housing 11 side of the discharge channel 15 is thereby opened. In the present invention, these configurations are referred to as weak parts.
In addition, the angle θ between the pair of operation protrusions 21a and 21b is preferably 20 ° to 120 °, particularly 40 ° to 80 °. This is because it is easy to ensure good operability.

このような薬剤入り可撓性容器10を使用するには、次のように行う。
予め、収容室11に内視鏡使用時に投与される薬剤が収容された状態で可撓性容器10を製造して必要に応じて保存しておく。内視鏡使用時には、まず、タンパプルーフ用シール15cを剥離除去した後、図2に示すように、内視鏡25のかん子口27に導出部17bを挿入して配置する。
In order to use such a flexible container 10 with a medicine, it is performed as follows.
The flexible container 10 is manufactured in advance in a state in which a medicine to be administered when the endoscope is used is stored in the storage chamber 11 and stored as necessary. When the endoscope is used, first, the tamper-proof seal 15c is peeled and removed, and then the lead-out portion 17b is inserted and disposed in the lever opening 27 of the endoscope 25 as shown in FIG.

次に、使用者が手で収容室11に対応する可撓性容器本体13を把持し、その外側から強く圧迫する。このとき、互いに離間した両縁部13e、好ましくは両縁部13e及び傾斜縁13cを同時に把持圧迫することにより、可撓性容器本体13を変形させつつ操作突起21a、21bを互いに近接させるように相対変位させる。すると、図3に示すように、操作突起21bに対して操作突起21aが変位し、排出部17の基部17aと操作突起21aとの間の閉塞部19に設けられた括れ部23が破断される。これにより、排出流路15の収容室11側が開口する。   Next, the user grips the flexible container body 13 corresponding to the storage chamber 11 by hand and strongly presses it from the outside. At this time, the operating projections 21a and 21b are brought close to each other while deforming the flexible container body 13 by simultaneously gripping and compressing both the edge portions 13e, preferably the both edge portions 13e and the inclined edge 13c, which are separated from each other. Make relative displacement. Then, as shown in FIG. 3, the operation projection 21a is displaced with respect to the operation projection 21b, and the constricted portion 23 provided in the closing portion 19 between the base portion 17a of the discharge portion 17 and the operation projection 21a is broken. . Thereby, the storage chamber 11 side of the discharge flow path 15 is opened.

そして、そのまま更に強く収容室11に対応する可撓性容器本体13の外側を圧迫すると、収容室11内に収容されていた薬剤が排出流路15を経由してかん子口27に供給され、このかん子口27を経由して内視鏡25の先端から、患部に直接投与される。
全量或いは所望量を投与した後、把持した状態でそのまま導出部17bをかん子口27から抜き出せば、廃棄することができ、これにより使用を終了することができる。
When the outer side of the flexible container body 13 corresponding to the storage chamber 11 is further strongly pressed as it is, the medicine stored in the storage chamber 11 is supplied to the cannula port 27 via the discharge channel 15. It is directly administered to the affected area from the distal end of the endoscope 25 via the lever opening 27.
After the entire amount or the desired amount has been administered, if the lead-out part 17b is pulled out from the lever 27 as it is, it can be discarded and the use can be terminated.

以上のような可撓性容器10によれば、複数の操作突起21a、21bが先端側を互いに離間させて可撓性容器本体13の外側から、例えば圧迫等により相対変位可能に配置され、この複数の操作突起21a、21bの圧迫による相対変位で、排出流路15を閉塞する閉塞部19が開口可能に構成されているので、可撓性容器本体13と共に複数の操作突起21a、21bを圧迫等により相対変位させることで、排出流路15の収容室11側の閉塞部19を開口させることができ、排出流路15の開口操作が容易である。
しかも、開口操作後に収容室11から薬剤を排出させる排出操作も、収容室11が設けられた可撓性容器本体13を外側から圧迫して行うため、排出流路15の閉塞部19の開口操作から連続して薬剤の排出操作を行うことができる。そのため、開口操作と排出操作とを別々に行う必要がなくて操作が単純であり、操作中の可撓性容器13の持ちかえなどの手間も抑えることができ、使用時の操作性が良好である。
更に、圧迫等により複数の操作突起21a、21bを相対変位することで排出流路15を開口させるように構成しただけであるため構造が簡単であると共に、その複数の操作突起21a、21bが可撓性容器本体13内に配置されるため小型化をも図ることができる。
According to the flexible container 10 as described above, the plurality of operation projections 21a and 21b are disposed so as to be relatively displaceable from the outside of the flexible container body 13 by, for example, compression, with the distal ends separated from each other. Since the closing portion 19 that closes the discharge channel 15 can be opened by relative displacement due to the compression of the plurality of operation protrusions 21a and 21b, the plurality of operation protrusions 21a and 21b are compressed together with the flexible container body 13. By relatively displacing the discharge channel 15 or the like, it is possible to open the closing portion 19 on the storage chamber 11 side of the discharge channel 15, and the opening operation of the discharge channel 15 is easy.
Moreover, since the discharge operation for discharging the medicine from the storage chamber 11 after the opening operation is also performed by pressing the flexible container body 13 provided with the storage chamber 11 from the outside, the opening operation of the closing portion 19 of the discharge flow path 15 is performed. The medicine discharge operation can be performed continuously. Therefore, it is not necessary to perform the opening operation and the discharge operation separately, and the operation is simple, and it is possible to reduce the trouble of holding the flexible container 13 during the operation, and the operability during use is good. is there.
Further, since the discharge channel 15 is simply opened by relatively displacing the plurality of operation projections 21a and 21b by compression or the like, the structure is simple and the plurality of operation projections 21a and 21b are possible. Since it is arranged in the flexible container main body 13, the size can be reduced.

また、閉塞部19が複数の操作突起21a、21bの相対変位により破断して開口されるように構成されているので、排出部15や複数の操作突起21a、21bと一体に閉塞部19を作製することができ、部品点数を少なくして、より構成を簡単にすることができる。   In addition, since the closing portion 19 is configured to be opened by being broken due to the relative displacement of the plurality of operation protrusions 21a and 21b, the closing portion 19 is manufactured integrally with the discharge portion 15 and the plurality of operation protrusions 21a and 21b. Therefore, the number of parts can be reduced and the configuration can be simplified.

更に、開口形成部として、収容室11と排出流路15との間を仕切る閉塞部19に形成された括れ部23を用いているので、開口形成部の位置、大きさ、破断強度などを設定し易く、可撓性容器10の品質を安定化し易い。   Further, since the constricted portion 23 formed in the closing portion 19 that partitions the storage chamber 11 and the discharge flow path 15 is used as the opening forming portion, the position, size, breaking strength, etc. of the opening forming portion are set. And the quality of the flexible container 10 can be easily stabilized.

また、複数の操作突起21a、21bの先端側が収容室11に配置されると共に、互いに近接する方向に相対変位可能に構成されているので、可撓性容器本体13の外側から可撓性容器本体13を圧迫して複数の操作突起21a、21bを操作すれば、極めて容易に開口操作と排出操作とを連続して行うことが可能である。   In addition, since the distal ends of the plurality of operation projections 21a and 21b are disposed in the storage chamber 11 and are configured to be relatively displaceable in directions close to each other, the flexible container body 13 is formed from the outside of the flexible container body 13. If the plurality of operation protrusions 21a and 21b are operated by pressing the pressure 13, the opening operation and the discharging operation can be performed very easily and continuously.

更に、可撓性容器本体13が扁平形状を呈し、複数の操作突起21a、21bが互いに離間する縁部13e、13eに沿って配置されているので、収容室11の容積がより小さい可撓性容器本体13であっても、可撓性容器本体13の変形量を大きく確保し易いと共に複数の操作突起21a、21bを互いにより離間して配置し易い。そのため、使用時の操作の確実性を向上し易い。
しかも、可撓性容器10を長期間保存するなどにより、収容室11内にエアーが充満されて可撓製容器本体13が膨張した場合であっても、確実に、排出操作を行うことができ、長期間保存時の使い勝手も確保し易い。
Further, since the flexible container body 13 has a flat shape and the plurality of operation protrusions 21a and 21b are arranged along the edge portions 13e and 13e that are separated from each other, the flexibility of the storage chamber 11 is smaller. Even in the case of the container body 13, it is easy to ensure a large deformation amount of the flexible container body 13, and it is easy to dispose the plurality of operation protrusions 21a and 21b further apart from each other. Therefore, it is easy to improve the certainty of operation at the time of use.
Moreover, even when the flexible container 10 is stored for a long period of time, even if the container 11 is filled with air and the flexible container body 13 expands, the discharge operation can be performed reliably. Easy to use for long-term storage.

また、可撓性容器本体13が排出部15側の端部13aから他方側の端部13bに向けて拡幅する傾斜縁13cを有し、複数の操作突起21a、21bが傾斜縁13cに沿って配置されているので、使用者の手の大きさに拘わらず、開口操作や排出操作を行い易い幅で使用者が可撓性容器を把持することができ、より使い勝手がよい。   The flexible container body 13 has an inclined edge 13c that widens from the end portion 13a on the discharge portion 15 side toward the other end portion 13b, and a plurality of operation protrusions 21a and 21b extend along the inclined edge 13c. Since it is arranged, the user can hold the flexible container with a width that allows easy opening and discharge operations regardless of the size of the user's hand, and is more convenient to use.

また、複数の操作突起21a、21bが可撓性容器本体13の傾斜縁13cに沿って配置されており、かつ、複数の操作突起21a、21bが可撓性容器本体13の長さ(高さ)の略半分以上の長さ(高さ)を有しているので、この複数の操作突起21a、21bが可撓性容器10を把持する際の把持部としても機能する。
このため、可撓性容器10を、例えば、内視鏡のかん子や他の容器に接続しようとする際には、可撓性容器本体13の外部から複数の操作突起21a、21bを間接的に軽く把持すれば、可撓性容器10を極めて容易に把持することができ、可撓性容器10を内視鏡のかん子や他の容器へ接続する際の作業も極めて良好である。
Further, the plurality of operation protrusions 21a and 21b are arranged along the inclined edge 13c of the flexible container body 13, and the plurality of operation protrusions 21a and 21b are the length (height of the flexible container body 13). ) Has a length (height) that is approximately half or more of (), the plurality of operation protrusions 21 a and 21 b also function as a gripping portion when gripping the flexible container 10.
For this reason, when trying to connect the flexible container 10 to, for example, an endoscope lever or another container, the plurality of operation protrusions 21 a and 21 b are indirectly connected from the outside of the flexible container body 13. If the container is lightly grasped, the flexible container 10 can be grasped very easily, and the work when the flexible container 10 is connected to the canister of the endoscope or another container is also very good.

そして、このような可撓性容器10に薬剤が収容されているので、使用者がシリンジ等の注射薬等と見誤ることがなく、薬剤使用時の安全性を向上できる。また、排出流路15の開口操作と薬剤の排出操作とを連続的に一連で行うことができるため、排出流路3の開口後に導出部17b周辺に菌が付着して汚染されるような機会を抑えることができる。   And since the chemical | medical agent is accommodated in such a flexible container 10, a user does not misunderstand injection drugs, such as a syringe, and can improve the safety | security at the time of chemical | medical agent use. In addition, since the opening operation of the discharge flow channel 15 and the discharge operation of the medicine can be performed continuously in series, there is an opportunity for the bacteria to adhere to the periphery of the lead-out portion 17b after the discharge flow channel 3 is opened and be contaminated. Can be suppressed.

しかも、収容室11に収容された薬剤の封入量が一回の投与量相当であるので、過剰投与の危険がなく、一旦、排出流路15を開口させて収容物を排出させた後は、保存して再使用する必要がなく、開口後に収容物の無菌性などを維持するための特別な手段が不要で、構成を簡単にすることができる。   Moreover, since the enclosed amount of the medicine stored in the storage chamber 11 is equivalent to a single dose, there is no danger of overdose, and once the discharge channel 15 is opened and the stored items are discharged, There is no need for storage and reuse, and no special means for maintaining the sterility or the like of the contents after opening is unnecessary, and the configuration can be simplified.

なお、上述の実施の形態1では、一つの操作突起21aの排出部17側の全周囲に括れ部23を設けた例について説明したが、括れ部23を操作突起21aの相対移動の方向に応じた一部にのみ設けておくことも可能である。更に、上述では、括れ部23が排出流路15の一部を囲む位置に形成されているが、少なくとも一部が排出流路15の内壁面に破断可能に近接していればよい。
また、このような括れ部23を設けなくても、閉塞部19を破断可能な脆弱部を有していてもよい。単に排出流路15と収容室11との間を仕切る破断可能な閉塞部19であってもよく、更には他の部材や栓体を接着、溶着して操作突起部21の相対変位で剥離、離脱して開口するようにしてもよい。
また、上述の実施の形態にあっては、複数の操作突起21a、21bが可撓性容器本体13と別体のものを例示したが、例えば、2本の操作突起21a、21bを可撓性容器本体13の傾斜部13cの縁部に設け、可撓性容器本体13を構成する容器壁を2本の操作突起21a、21bに溶着するようにして、2本の操作突起21a、21bが可撓性容器本体13の縁部の一部を構成するようにしてもよい。
In the first embodiment described above, the example in which the constricted portion 23 is provided on the entire periphery on the discharge portion 17 side of one operation projection 21a has been described. However, the constricted portion 23 is set according to the direction of relative movement of the operation projection 21a. It is also possible to provide it only in a part. Furthermore, in the above description, the constricted portion 23 is formed at a position surrounding a part of the discharge channel 15, but at least a part of the constricted part 23 only needs to be proximate to the inner wall surface of the discharge channel 15.
Further, even if such a constricted portion 23 is not provided, a fragile portion that can break the closing portion 19 may be provided. It may be a breakable closing part 19 that simply partitions between the discharge flow path 15 and the storage chamber 11, and further peels off by relative displacement of the operation projection part 21 by adhering and welding other members and plugs, You may make it open | separate and open.
In the above-described embodiment, the plurality of operation protrusions 21a and 21b are illustrated separately from the flexible container body 13. However, for example, the two operation protrusions 21a and 21b are flexible. Two operation projections 21a and 21b are possible by providing the container wall constituting the flexible container body 13 on the edge of the inclined portion 13c of the container body 13 and welding the two operation projections 21a and 21b. You may make it comprise a part of edge part of the flexible container main body 13. As shown in FIG.

[発明の実施の形態2]
図4(a)〜(c)は、この実施の形態2の可撓性容器30を示している。
この可撓性容器30は、可撓性容器本体13の排出部17側の傾斜縁13dが排出部17の一方側に設けられ、操作突起部21の複数の操作突起21a、21bが異なる形状の可撓性容器本体13の両縁部13eに沿って配置されている他は、全て実施の形態1と同様である。
[Embodiment 2 of the Invention]
4A to 4C show the flexible container 30 of the second embodiment.
The flexible container 30 has an inclined edge 13d on the discharge part 17 side of the flexible container body 13 provided on one side of the discharge part 17, and the plurality of operation protrusions 21a and 21b of the operation protrusion part 21 have different shapes. Except for being disposed along both edge portions 13e of the flexible container main body 13, all are the same as in the first embodiment.

このような可撓性容器30であっても、使用時には、収容室11に対応する外側から可撓性容器本体13を把持して圧迫すれば、操作突起21bに対して操作突起21aだけを近接方向に相対移動させ易く、括れ部23をより容易に破断させることができる。その結果、実施の形態1と全く同様にして使用することが可能であり、同様の効果を得ることが可能である。   Even when such a flexible container 30 is used, if the flexible container body 13 is gripped and pressed from the outside corresponding to the storage chamber 11, only the operation protrusion 21a is brought close to the operation protrusion 21b. The constricted portion 23 can be easily broken by being relatively moved in the direction. As a result, it can be used in the same manner as in the first embodiment, and the same effect can be obtained.

なお、上記実施の形態1及び2では、何れも操作突起部21及び閉塞部19が排出部17と全て一体に成形されたものについて説明したが、例えば、図5に示すように、操作突起部21の一部、例えば操作突起21aだけを残部と異なる物品として形成した後、排出部17側に剥離可能に溶着等により接合することも可能である。この場合、接合強度を調整することにより、使用時の操作突起部21の操作荷重を調整することも可能である。   In the first and second embodiments, the operation projection 21 and the closing portion 19 are all formed integrally with the discharge portion 17. However, for example, as shown in FIG. It is also possible to form a part of 21, for example, only the operation projection 21 a as an article different from the remaining part, and then bond it to the discharge part 17 side by welding or the like so as to be peeled off. In this case, it is possible to adjust the operation load of the operation projection 21 during use by adjusting the bonding strength.

また、上記実施の形態1及び2では、排出部17の導出部17bの端部にタンパプルーフ用シール15dを装着した例についてのみ説明したが、例えば、図6に示すように、導出部17bの先端を被覆するキャップ部材33を装着するなどであってもよい。   In the first and second embodiments, only the example in which the tamper-proof seal 15d is attached to the end portion of the outlet portion 17b of the discharge portion 17 has been described. For example, as shown in FIG. A cap member 33 that covers the tip may be attached.

[発明の実施の形態3]
図7(a)〜(c)はこの実施の形態3の可撓性容器40を示している。
実施の形態1、2では、収容室11に直接投与用薬剤を収容したが、この実施の形態3の可撓性容器40では間接投与用薬剤を収容している。具体的には、収容室11に他の薬剤容器に混合するための薬剤が収容されている。そのため、排出部17には基部17aから外側に向けて混注針部17cが設けられている。
また、操作突出部21が、排出部17から収容室11側に延出し、扁平形状の可撓性容器本体13の互いに対向する容器壁方向、即ち、厚さ方向に、先端側が互いに離間して配置された一対の操作突起片21c、21dからなり、可撓性容器本体13の外側から操作可能となっている。その他は、実施の形態1と同様に構成されている。
Embodiment 3 of the Invention
7A to 7C show the flexible container 40 of the third embodiment.
In the first and second embodiments, the drug for direct administration is stored in the storage chamber 11, but the drug for indirect administration is stored in the flexible container 40 of the third embodiment. Specifically, a medicine for mixing in another medicine container is housed in the housing chamber 11. For this reason, the discharge portion 17 is provided with a mixed injection needle portion 17c from the base portion 17a toward the outside.
Further, the operation projecting portion 21 extends from the discharge portion 17 to the storage chamber 11 side, and the distal end sides are separated from each other in the container wall direction of the flat flexible container body 13 facing each other, that is, in the thickness direction. It consists of a pair of operation protrusion pieces 21 c and 21 d arranged, and can be operated from the outside of the flexible container body 13. Others are configured in the same manner as in the first embodiment.

このような構成を有する可撓性容器40では、図8に示すように、他の薬液容器41のゴム栓42に混注針部17cを刺通させ、その後に可撓性容器本体13の外側から厚さ方向に圧迫する。これにより、図7(c)に示すように、操作突起片21c、21dを互いに近接させる方向に変位させて括れ部23を破断させ、排出流路15と収容室11との間の閉塞部19を開口させる。そして、この状態で収容室11に対応する可撓性容器本体13を変形させることにより、収容室11内の混注用の薬剤を排出流路15を経由して他の薬液容器41内に供給することができる。   In the flexible container 40 having such a configuration, as shown in FIG. 8, the mixed injection needle portion 17 c is pierced through the rubber stopper 42 of another chemical liquid container 41, and thereafter, from the outside of the flexible container body 13. Press in the thickness direction. As a result, as shown in FIG. 7C, the operating projection pieces 21 c and 21 d are displaced in the direction of approaching each other to break the constricted portion 23, and the blocking portion 19 between the discharge flow path 15 and the storage chamber 11. Open. In this state, the flexible container main body 13 corresponding to the storage chamber 11 is deformed to supply the mixed injection medicine in the storage chamber 11 into the other chemical solution container 41 via the discharge flow path 15. be able to.
