本発明は、投薬容器用ノズル及び投薬容器に関する。 The present invention relates to a nozzle for a dosing container and a dosing container.

嚥下障害等により口から栄養が取れない患者の場合、経鼻胃管、胃瘻、腸瘻等の経管栄養補給法が行われている。このような経管栄養補給法では、ボトルやバッグ(以下、「投薬容器」という)に栄養剤を入れ、チューブを介して胃や腸に注入する。投薬容器には、排出部にノズルが設けられ、該ノズルにチューブが接続される。 For patients who cannot get nutrition from the mouth due to dysphagia or the like, tube feeding methods such as nasogastric tube, gastrostomy, and intestinal fistula are performed. In such a tube feeding method, a nutritional supplement is put in a bottle or a bag (hereinafter referred to as a “medication container”) and injected into the stomach or intestine via a tube. The dosing container is provided with a nozzle at the discharge portion, and a tube is connected to the nozzle.

近年、経腸栄養の分野では、相互接続防止コネクタとして、国際規格ISO(IEC)80369-3に規定されたねじ込み式のコネクタの適用が予定されている。 In recent years, in the field of enteral nutrition, the application of a screw-in type connector specified in the international standard ISO (IEC) 80369-3 is planned as an interconnection prevention connector.

従来、投薬容器用ノズルの構造として種々提案されている。例えば、特許文献1には、容器のノズルに隔壁が設けられ、先端に接続針が設けられたカテーテルをノズルにねじ込む過程で、接続針が隔壁を破断するカテーテル接続構造が記載されている。この構造では、雄コネクタに接続針を設ける必要があるため、前記ISO80369-3のコネクタには適用できない。 Conventionally, various proposals have been made as a structure of a nozzle for a dosing container. For example,Patent Document 1 describes a catheter connection structure in which a partition wall is provided on the nozzle of a container and the connecting needle breaks the partition wall in the process of screwing a catheter provided with a connecting needle at the tip into the nozzle. In this structure, since it is necessary to provide a connecting needle to the male connector, it cannot be applied to the ISO80369-3 connector.

また、特許文献2-4には、キャップのねじ込みによって容器の口部に設けたシール材を破断する技術が公知であるが、これを前記ISO80369-3のコネクタに適用するとしても、雄コネクタ又は雌コネクタに加工が必要であるため、投薬容器用ノズルには適用できない。 Further, Patent Document 2-4 knows a technique of breaking a sealing material provided at the mouth of a container by screwing a cap, but even if this is applied to the connector of ISO80369-3, a male connector or a male connector or Since the female connector needs to be processed, it cannot be applied to the nozzle for medication containers.

また、特許文献5には、投薬容器に収容部とノズルからなる排出部とを備え、収容部と排出部との境界部分を閉塞する閉塞部をさらに備え、収容部に医薬品と液体を収容して、医薬品を崩壊、懸濁させて、収容部に力を加えて閉塞部を開き、収容部内の医薬品と液体の混合物を排出部のノズルを経てチューブに流出することができる投薬容器が記載されている。この投薬容器の排出部には、前記ISO80369-3のコネクタを取り付けることは可能であるが、コネクタの接続と閉塞部の解放との2つの動作が必要であり、内容部物の補給動作が容易ではない。 Further, inPatent Document 5, the medication container is provided with a storage portion and a discharge portion including a nozzle, and further includes a closing portion for closing the boundary portion between the storage portion and the discharge portion, and the storage portion stores medicines and liquids. Described is a dosing container capable of disintegrating and suspending a drug, applying force to the containment to open the closure, and allowing a mixture of the drug and liquid in the containment to flow out into a tube through a nozzle in the discharge section. ing. Although it is possible to attach the ISO80369-3 connector to the discharge part of the dosing container, two operations of connecting the connector and releasing the closed part are required, and it is easy to replenish the contents. is not it.

ノズル本体11の基部13は、図3に示すように、横断面が菱形で、対向する鈍角の角部が円弧で形成されている。基部13には、雌コネクタ14の内部と連通する貫通孔15が形成されている。基部13は、投薬容器1の収容部6に臨む内端面16を有している。基部13の内端面16には、図4に示すように、貫通孔15と同心の環状突部17が形成されている。環状突部17は、図5に示すように、基端から先端に向かって径が大きくなるように傾斜し、先端には内側に向かって突出する係止部18が形成されている。 As shown in FIG. 3, thebase portion 13 of thenozzle body 11 has a rhombic cross section and opposite obtuse-angled corners formed by an arc. Thebase 13 is formed with a throughhole 15 that communicates with the inside of thefemale connector 14. Thebase 13 has aninner end surface 16 facing theaccommodating portion 6 of themedication container 1. As shown in FIG. 4, anannular protrusion 17 concentric with the throughhole 15 is formed on theinner end surface 16 of thebase portion 13. As shown in FIG. 5, theannular protrusion 17 is inclined so that the diameter increases from the base end toward the tip end, and a lockingportion 18 projecting inward is formed at the tip end.

ノズル本体11の雌コネクタ14は、図2に示すように、基部13の貫通孔に連通する円筒形状を有し、外周面に雄ねじ14aが形成されている。雌コネクタ14には、図1に示すように、経鼻胃管、又は胃瘻や腸瘻のカテーテルに接続されたチューブ(以下、単に「チューブ)という)26の雄コネクタ27がねじ込んで装着される。雄コネクタ27は、図2に示すように、雌コネクタ14に挿入される円筒部27aと、雌コネクタ14の雄ねじ14aに螺合する雌ねじ27bが形成された外筒部27cとからなる。雌コネクタ14と雄コネクタ27は、ISO80369-3に規定された寸法を有する。 As shown in FIG. 2, thefemale connector 14 of thenozzle body 11 has a cylindrical shape communicating with the through hole of thebase 13, and amale screw 14a is formed on the outer peripheral surface. As shown in FIG. 1, amale connector 27 of a tube (hereinafter, simply referred to as “tube”) 26 connected to a nasogastric tube or a catheter for a gastrostomy or an intestinal fistula is screwed and attached to thefemale connector 14. As shown in FIG. 2, themale connector 27 includes acylindrical portion 27a inserted into thefemale connector 14 and anouter cylinder portion 27c formed with afemale screw 27b screwed into themale screw 14a of thefemale connector 14. Thefemale connector 14 and themale connector 27 have the dimensions specified in ISO80369-3.

スライド部材12は、軸部19と、該軸部19の基端に設けられた弁部20とを有している。軸部19は、ノズル本体11の貫通孔15にスライド可能に挿入されている。軸部19は、円筒形で、ノズル本体11の基部13よりも長い長さを有する。このため、軸部19をノズル本体11の貫通孔15に挿入し、弁部20をノズル本体11の基部13の内端面16に当接したときに、軸部19の先端が雌コネクタ14の内部に突出するようになっている。軸部19は、雌コネクタ14の流体ルーメン内径d1より小さく、雄コネクタ27の内筒部27aの内径d2より大きい外径Dを有し、雄コネクタ27の内筒部27aの先端に当接するようになっている。 Theslide member 12 has ashaft portion 19 and avalve portion 20 provided at the base end of theshaft portion 19. Theshaft portion 19 is slidably inserted into the throughhole 15 of thenozzle body 11. Theshaft portion 19 is cylindrical and has a length longer than that of thebase portion 13 of thenozzle body 11. Therefore, when theshaft portion 19 is inserted into the throughhole 15 of thenozzle body 11 and thevalve portion 20 comes into contact with theinner end surface 16 of thebase portion 13 of thenozzle body 11, the tip of theshaft portion 19 is inside thefemale connector 14. It is designed to protrude into. Theshaft portion 19 has an outer diameter D smaller than the fluid lumen inner diameter d1 of thefemale connector 14 and larger than the inner diameter d2 of theinner cylinder portion 27a of themale connector 27 so as to abut on the tip of theinner cylinder portion 27a of themale connector 27. It has become.

軸部19の基端側には、2つの流入口22が対向する位置に形成されている。2つの流入口22は、それぞれ長円形状で、軸部19の内部の横断面積以上の開口面積を有する。2つの流入口22の弁部20からの位置は、軸部19をノズル本体11の貫通孔15に挿入し、弁部20をノズル本体11の基部13の内端面16に当接したときに、ノズル本体11の基部13内に潜伏し、雌コネクタ14に雄コネクタ27を装着することにより軸部19が投薬容器1の収容部6側に移動したときに、ノズル本体11の基部13から露出するような位置に形成されている。 Twoinflow ports 22 are formed at positions facing each other on the base end side of theshaft portion 19. Each of the twoinlets 22 has an oval shape and has an opening area equal to or larger than the cross-sectional area inside theshaft portion 19. The positions of the twoinlets 22 from thevalve portion 20 are such that when theshaft portion 19 is inserted into the throughhole 15 of thenozzle body 11 and thevalve portion 20 abuts on theinner end surface 16 of thebase portion 13 of thenozzle body 11. It is hidden in thebase 13 of thenozzle body 11 and is exposed from thebase 13 of thenozzle body 11 when theshaft portion 19 is moved to theaccommodating portion 6 side of themedication container 1 by attaching themale connector 27 to thefemale connector 14. It is formed in such a position.

スライド部材12の弁部20は、円形で、軸部19の基端に軸部19と同心に一体に形成されている。弁部20の下面は、ノズル本体11の基部13の内端面16と接触し、離間するように形成されている。弁部20の外周面21は、図5に示すように、軸部19に向かって先細りになるように傾斜し、ノズル本体11の環状突部17の内面に密着するように形成されている。 Thevalve portion 20 of theslide member 12 is circular and is formed concentrically with theshaft portion 19 at the base end of theshaft portion 19. The lower surface of thevalve portion 20 is formed so as to be in contact with and separated from theinner end surface 16 of thebase portion 13 of thenozzle body 11. As shown in FIG. 5, the outerperipheral surface 21 of thevalve portion 20 is formed so as to be inclined so as to taper toward theshaft portion 19 and to be in close contact with the inner surface of theannular protrusion 17 of thenozzle body 11.

弁部20の外周面21と、ノズル本体11の基部13の環状突部17は、投薬容器1の収容部6から、ノズル本体11の基部13の内端面16とスライド部材12の弁部20との間を通って、流入口22、軸部19の内部を経て外部に至る流路をシールするシール部23を構成している。シール部23は、環状突部17の上端に形成された係止部18が弁部20の外周縁に係止することでシール状態に維持している。 The outerperipheral surface 21 of thevalve portion 20 and theannular protrusion 17 of thebase 13 of thenozzle body 11 are from theaccommodating portion 6 of themedication container 1 to theinner end surface 16 of thebase 13 of thenozzle body 11 and thevalve portion 20 of theslide member 12. It constitutes a sealingportion 23 that seals a flow path that passes through the space, passes through the inside of theinflow port 22 and theshaft portion 19, and reaches the outside. Theseal portion 23 is maintained in a sealed state by engaging the lockingportion 18 formed at the upper end of theannular protrusion 17 with the outer peripheral edge of thevalve portion 20.

次に、前記構成のノズル10を備えた投薬容器1を使用して簡易懸濁法により投薬を行う場合における特にノズル10の作用を説明する。 Next, the operation of thenozzle 10 in particular when the dosing is performed by the simple suspension method using thedosing container 1 provided with thenozzle 10 having the above configuration will be described.

投薬容器1の排出部5のノズル10のスライド部材12の弁部20が閉じ、ノズル本体11の係止部18がスライド部材12の弁部20に係止していることを確認してから、投薬容器1のチャックテープ9を開き、入口部8を広げて、患者の投薬に必要なカプセル剤や錠剤等の医薬品と、常温の水または55℃の温湯を入れて、チャックテープ9を閉じる。この状態で、投薬容器1を所定時間放置し、医薬品を崩壊、懸濁させる。必要に応じて、投薬容器1を振ったり、外側から外力を加えて医薬品を崩壊させてもよい。ノズル10は、スライド部材12の弁部20が閉じており、シール部23でシールされているので、投薬容器1の収容部6内の医薬品と温湯の懸濁液が外部に漏れることはない。懸濁中は、図6(a)に示すように、ノズル10を上にして、投薬容器1をノズル10側の吊り孔4aをスタンド24のフック25に掛けて吊るしてもよい。常温の水で懸濁した場合は、人の体温近くまで加温してもよい。 After confirming that thevalve portion 20 of theslide member 12 of thenozzle 10 of thedischarge portion 5 of themedication container 1 is closed and the lockingportion 18 of thenozzle body 11 is locked to thevalve portion 20 of theslide member 12. Thechuck tape 9 of themedication container 1 is opened, theinlet portion 8 is opened, a drug such as a capsule or a tablet necessary for the patient's medication, water at room temperature or hot water at 55 ° C. is put in, and thechuck tape 9 is closed. In this state, thedosing container 1 is left for a predetermined time to disintegrate and suspend the drug. If necessary, themedication container 1 may be shaken or an external force may be applied from the outside to disintegrate the drug. Since thevalve portion 20 of theslide member 12 is closed and thenozzle 10 is sealed by theseal portion 23, the suspension of the drug and the hot water in theaccommodating portion 6 of thedosing container 1 does not leak to the outside. During suspension, as shown in FIG. 6A, thedosing container 1 may be hung by hanging thesuspension hole 4a on thenozzle 10 side on thehook 25 of thestand 24 with thenozzle 10 facing up. When suspended in water at room temperature, it may be heated to near the human body temperature.

投薬容器1内の医薬品と温湯の懸濁液が体温に近い温度になると、図6(b)に示すように、投薬容器1のノズル10の雌コネクタ14にチューブ26の雄コネクタ27を接続する。このとき、図7に示すように、雄コネクタ27の先端にスライド部材12の軸部19の先端が当接して押し込まれる。 When the suspension of the drug and hot water in thedosing container 1 reaches a temperature close to the body temperature, themale connector 27 of thetube 26 is connected to thefemale connector 14 of thenozzle 10 of thedosing container 1 as shown in FIG. 6 (b). .. At this time, as shown in FIG. 7, the tip of theshaft portion 19 of theslide member 12 comes into contact with the tip of themale connector 27 and is pushed into the tip.

スライド部材12の軸部19が押し込まれることにより、スライド部材12の弁部20が、ノズル本体11の係止部18から外れてシール状態が解除され、スライド部材12の弁部20がノズル本体11の基部13の内端面16から離間して、弁部20が解放され、スライド部材12の軸部19の流入口22が投薬容器1の収容部6の内側に露出する。 When theshaft portion 19 of theslide member 12 is pushed in, thevalve portion 20 of theslide member 12 is disengaged from the lockingportion 18 of thenozzle body 11 and the sealed state is released, and thevalve portion 20 of theslide member 12 is released from thenozzle body 11. Thevalve portion 20 is released so as to be separated from theinner end surface 16 of thebase portion 13, and theinflow port 22 of theshaft portion 19 of theslide member 12 is exposed to the inside of theaccommodating portion 6 of themedication container 1.

これにより、スライド部材12の弁部20と、ノズル本体11の基部13の内端面16との間から、スライド部材12の軸部19の2つの流入口22を経て、軸部19の内部に流路が形成され、この流路を通って投薬容器1の収容部6の懸濁液がチューブ26を介して患者の胃や腸に投与される。スライド部材12の軸部19の先端は、チューブ26の雄コネクタ27の先端に当接しているので、懸濁液の流動中にスライド部材12が戻ることはない。 As a result, the liquid flows from between thevalve portion 20 of theslide member 12 and theinner end surface 16 of thebase portion 13 of thenozzle body 11 to the inside of theshaft portion 19 via the twoinlets 22 of theshaft portion 19 of theslide member 12. A passage is formed, through which the suspension of thecontainer 6 of thedosing container 1 is administered to the patient's stomach or intestine via thetube 26. Since the tip of theshaft portion 19 of theslide member 12 is in contact with the tip of themale connector 27 of thetube 26, theslide member 12 does not return during the flow of the suspension.

懸濁液の投与が終わると、チューブ26の雄コネクタ27を外し、ノズル10のスライド部材12の弁部20を投薬容器1の外側から押さえて、弁部20の外周縁をノズル本体11の係止部18に係止する。これにより、スライド部材12が閉じるので、収容部6に付着又は残留している懸濁液を外部に漏らさずに投薬容器1を廃棄することができる。なお、スライド部材12の弁部20を閉じずに投薬容器1を廃棄してもよい。 When the administration of the suspension is completed, themale connector 27 of thetube 26 is removed, thevalve portion 20 of theslide member 12 of thenozzle 10 is pressed from the outside of themedication container 1, and the outer peripheral edge of thevalve portion 20 is engaged with thenozzle body 11. Locks to thestop 18. As a result, theslide member 12 is closed, so that thedosing container 1 can be discarded without leaking the suspension adhering to or remaining in theaccommodating portion 6 to the outside. Thedosing container 1 may be discarded without closing thevalve portion 20 of theslide member 12.

前記第1実施形態では、スライド部材12の軸部19は、円筒形であるが、図8に示すように、横断面が十字形の棒状にしてもよい。このため、スライド部材12の弁部20が開くと、スライド部材12の軸部31の溝28が投薬容器1の収容部6の内側に露出する。これにより、スライド部材12の弁部20と、ノズル本体11の基部13の内端面16との間から、スライド部材12の軸部31の溝28を通る流路が形成され、この流路を通って投薬容器1の収容部6の懸濁液がチューブ26を介して患者の胃や腸に投与される。 In the first embodiment, theshaft portion 19 of theslide member 12 has a cylindrical shape, but as shown in FIG. 8, theshaft portion 19 may have a cross-shaped cross section. Therefore, when thevalve portion 20 of theslide member 12 is opened, thegroove 28 of theshaft portion 31 of theslide member 12 is exposed inside theaccommodating portion 6 of thedosing container 1. As a result, a flow path is formed between thevalve portion 20 of theslide member 12 and theinner end surface 16 of thebase portion 13 of thenozzle body 11 through thegroove 28 of theshaft portion 31 of theslide member 12, and passes through this flow path. The suspension of thecontainer 6 of thedosing container 1 is administered to the patient's stomach and intestine via thetube 26.

また、図9に示すように、ノズル本体11の基部13の内端面16に環状溝29aを形成し、スライド部材12の弁部20に環状溝29aと嵌合する環状突起29bを設けて、環状溝29aと環状突起29bの嵌合によりシール部29を構成してもよい。 Further, as shown in FIG. 9, anannular groove 29a is formed on theinner end surface 16 of thebase portion 13 of thenozzle body 11, and anannular protrusion 29b that fits with theannular groove 29a is provided on thevalve portion 20 of theslide member 12, and is annular. Theseal portion 29 may be formed by fitting thegroove 29a and theannular protrusion 29b.

図10は、第2実施形態のノズル10Aを示す。このノズル10Aは、シール部の構造と、スライド部材の形状が異なる以外は、前記第1実施形態のノズル10と同様であるので、対応する部分には同一符号を附して説明を省略する。
<Second Embodiment>
FIG. 10 shows thenozzle 10A of the second embodiment. Thenozzle 10A is the same as thenozzle 10 of the first embodiment except that the structure of the seal portion and the shape of the slide member are different. Therefore, the same reference numerals are given to the corresponding portions and the description thereof will be omitted.

シール部は、投薬容器1の収容部6を臨む内端面16に、貫通孔15を覆うように接着されたシート材30からなる。シート材30は、投薬容器1のシート2a,2bと同様に、ポリエチレン等の軟質の合成樹脂で形成されている。図11に示すように、シート材30の中心から放射状に周囲より肉厚が薄い弱め線31が形成され、中心に押圧力を受けたときに弱め線31に沿って破断するようになっている。 The sealing portion is made of asheet material 30 bonded to theinner end surface 16 facing theaccommodating portion 6 of themedication container 1 so as to cover the throughhole 15. Thesheet material 30 is made of a soft synthetic resin such as polyethylene, similarly to thesheets 2a and 2b of thedosage container 1. As shown in FIG. 11, a weakeningline 31 whose wall thickness is thinner than the surroundings is formed radially from the center of thesheet material 30, and breaks along the weakeningline 31 when a pressing force is applied to the center. ..

スライド部材12は、軸部19の先端にシート材30に対向する円錐状の尖鋭端32を有し、該尖鋭端32によりシート材30を突き破るように構成されている。スライド部材12の軸部19の外周には、スライド部材12が雌コネクタ14から抜け出るのを防止するストッパ33が設けられている。 Theslide member 12 has a conicalsharp end 32 facing thesheet material 30 at the tip of theshaft portion 19, and is configured to penetrate thesheet material 30 by thesharp end 32. Astopper 33 is provided on the outer periphery of theshaft portion 19 of theslide member 12 to prevent theslide member 12 from coming out of thefemale connector 14.

投薬容器1のノズル10Aの雌コネクタ14にチューブ26の雄コネクタ27を接続すると、図12に示すように、雄コネクタ27によりスライド部材12の軸部19が押し込まれ、スライド部材12の尖鋭端32が、シート材30を突き破り、弱め線31に沿って破断する。この結果、シート材30のシール状態が解除され、スライド部材12の軸部19の流入口22が投薬容器1の収容部6の内側に露出する。 When themale connector 27 of thetube 26 is connected to thefemale connector 14 of thenozzle 10A of themedication container 1, theshaft portion 19 of theslide member 12 is pushed by themale connector 27 as shown in FIG. 12, and thesharp end 32 of theslide member 12 is pushed. However, it breaks through thesheet material 30 and breaks along the weakeningline 31. As a result, the sealed state of thesheet material 30 is released, and theinflow port 22 of theshaft portion 19 of theslide member 12 is exposed inside theaccommodating portion 6 of thedosing container 1.

これにより、投薬容器1の収容部6から、スライド部材12の軸部19の2つの流入口22を経て、軸部19の内部に流路が形成され、この流路を通って投薬容器1の収容部6の懸濁液がチューブ26を介して患者の胃や腸に投与される。 As a result, a flow path is formed from theaccommodating portion 6 of thedosing container 1 through the twoinlets 22 of theshaft portion 19 of theslide member 12 to the inside of theshaft portion 19, and thedosing container 1 passes through this flow path. The suspension of thecontainer 6 is administered to the patient's stomach or intestine via thetube 26.

<第3実施形態>
図13は、第3実施形態のノズル10Bを示す。このノズル10Bは、シール部の構造と、スライド部材の形状が異なる以外は、前記第1実施形態のノズル10と同様であるので、対応する部分には同一符号を附して説明を省略する。
<Third Embodiment>
FIG. 13 shows thenozzle 10B of the third embodiment. Thenozzle 10B is the same as thenozzle 10 of the first embodiment except that the structure of the seal portion and the shape of the slide member are different. Therefore, the same reference numerals are given to the corresponding portions and the description thereof will be omitted.

シール部は、投薬容器1の収容部6を臨む内端面16に、貫通孔15を覆うように接着されたシート材30からなる。シート材30は、投薬容器1のシート2a、2bと同様に、ポリエチレン等の軟質の合成樹脂で形成されている。シート材30の図14にハッチングで示す接着部30aは、中心に押圧力を受けたときに剥離するような接着力で内端面19に接着されている。 The sealing portion is made of asheet material 30 bonded to theinner end surface 16 facing theaccommodating portion 6 of themedication container 1 so as to cover the throughhole 15. Thesheet material 30 is made of a soft synthetic resin such as polyethylene, similarly to thesheets 2a and 2b of thedosage container 1. Theadhesive portion 30a shown by hatching in FIG. 14 of thesheet material 30 is adhered to theinner end surface 19 with an adhesive force that peels off when a pressing force is applied to the center.

スライド部材12は、軸部19の先端がシート材30に接着されている。軸部19の先端をシート材30に接着しなくてもよいが、この場合、第2実施形態のスライド部材と同様に、スライド部材12の軸部19の外周に、スライド部材12が雌コネクタ14から抜け出るのを防止するストッパ33を設けることが好ましい。 The tip of theshaft portion 19 of theslide member 12 is adhered to thesheet material 30. The tip of theshaft portion 19 does not have to be adhered to thesheet material 30, but in this case, theslide member 12 has afemale connector 14 on the outer periphery of theshaft portion 19 of theslide member 12, as in the slide member of the second embodiment. It is preferable to provide astopper 33 for preventing thestopper 33 from coming out of the.

投薬容器1のノズル10Aの雌コネクタ14にチューブ26の雄コネクタ27を接続すると、図15に示すように、雄コネクタ27により、スライド部材12の軸部19が押し込まれ、スライド部材12の先端が、シート材30を押し上げ、やがて、図16に示すように、シート材30の接着部30aが剥離する。この結果、シート材30のシール状態が解除され、スライド部材12の軸部19の流入口22が投薬容器1の収容部6の内側に露出する。 When themale connector 27 of thetube 26 is connected to thefemale connector 14 of thenozzle 10A of themedication container 1, as shown in FIG. 15, theshaft portion 19 of theslide member 12 is pushed by themale connector 27, and the tip of theslide member 12 is pushed. , Thesheet material 30 is pushed up, and eventually, as shown in FIG. 16, theadhesive portion 30a of thesheet material 30 is peeled off. As a result, the sealed state of thesheet material 30 is released, and theinflow port 22 of theshaft portion 19 of theslide member 12 is exposed inside theaccommodating portion 6 of thedosing container 1.

これにより、投薬容器1の収容部6から、スライド部材12の軸部19の2つの流入口22を経て、軸部19の内部に流路が形成され、この流路を通って投薬容器1の収容部6の懸濁液がチューブ26を介して患者の胃や腸に投与される。 As a result, a flow path is formed from theaccommodating portion 6 of thedosing container 1 through the twoinlets 22 of theshaft portion 19 of theslide member 12 to the inside of theshaft portion 19, and thedosing container 1 passes through this flow path. The suspension of thecontainer 6 is administered to the patient's stomach or intestine via thetube 26.
