本発明は、液体収容体に取り付けられ、チューブに取り付けられた雌コネクタと接続する雄コネクタに関する。 The present invention relates to a male connector attached to a liquid container and connected to a female connector attached to a tube.
従来、食事等を口から摂取できない場合の療法として、患者の腹部に形成された胃ろうにチューブを挿入し、そのチューブを介して、ボトルやバッグ等の液体収容体に収容された栄養剤、流動食、薬剤等といった経腸栄養剤を患者に投与する経腸栄養療法が知られている。 Conventionally, as a therapy when a meal or the like cannot be taken from the mouth, a tube is inserted into a gastric fistula formed in the abdomen of the patient, and through the tube, a nutrient contained in a liquid container such as a bottle or a bag, Enteral nutrition therapy in which enteral nutrients such as liquid foods and drugs are administered to patients is known.
また、従来、患者の静脈に輸液ラインを挿入し、その輸液ラインを介して、ブドウ糖等の栄養成分や薬剤成分を含む輸液を患者に投与する静脈栄養療法も知られている。 Conventionally, parenteral nutrition therapy is also known in which an infusion line is inserted into a patient's vein, and an infusion containing a nutritional component such as glucose or a pharmaceutical component is administered to the patient via the infusion line.
そのような療法に用いられている液体収容体や、その液体収容体とチューブや輸液ライン等とを接続するためのコネクタ等は、洗浄、消毒、経腸栄養剤や輸液の再充填を行い、再使用される場合がある。 The liquid container used in such therapy, connectors for connecting the liquid container and tubes, infusion lines, etc. are cleaned, disinfected, refilled with enteral nutrients and infusions, May be reused.
しかし、近年では感染防止の観点から、経腸栄養剤や輸液が充填されていて、雄コネクタ（例えば、特許文献１参照）が取り付けられている使い捨てのプレフィルド型の雄コネクタ付き液体収容体が普及しつつある。 However, in recent years, from the viewpoint of preventing infection, a disposable prefilled type liquid container with a male connector, which is filled with an enteral nutrient or an infusion solution and has a male connector (for example, see Patent Document 1), has become widespread. I am doing.
プレフィルド型の雄コネクタ付き液体収容体では、経腸栄養剤や輸液が充填された後、密閉をする必要がある。その密閉のための方法としては、雄コネクタに設けられた経腸栄養剤や輸液の吐出口アルミ薄膜や樹脂膜等のシール材を張り付ける方法や、吐出口を覆うようなキャップ部材を取り付ける方法がある。 In the liquid container with a prefilled male connector, it is necessary to seal it after filling with an enteral nutrient or an infusion solution. As a method for the sealing, a method of attaching a sealing material such as an enteral nutrient solution or an infusion port aluminum thin film or a resin film provided on the male connector, or a method of attaching a cap member covering the discharge port There is.
しかし、いずれの方法も、製造工程が増えて複雑になり、また、製造コストが増加してしまうという問題があった。 However, each method has a problem that the manufacturing process is increased and complicated, and the manufacturing cost is increased.
また、キャップ部材を取り付ける方法では、キャップ部材を取り外したときに吐出口の周辺に内容物が付着していることがあるという問題があった。 Further, the method of attaching the cap member has a problem that the contents may adhere to the periphery of the discharge port when the cap member is removed.
本発明は以上の点に鑑みてなされたものであり、容易に製造することができ、使用時に吐出口の周囲に内容物が付着することのない雄コネクタを備えたコネクタを提供することを目的とする。 The present invention has been made in view of the above points, and it is an object of the present invention to provide a connector having a male connector that can be easily manufactured and does not cause contents to adhere to the periphery of a discharge port during use. And
本発明の雄コネクタは、
液体収容体に取り付けられる接合部と、チューブに接続される雌コネクタと係合する台座部と有し、前記接合部と前記台座部とを貫通し、前記液体収容体に収容された液体が流れる貫通孔が設けられた雄コネクタであって、
前記貫通孔の前記台座部側には、該貫通孔の縁に架け渡される十字形状のリブ部と、前記貫通孔と前記リブ部とによって画成される開口を破断可能な薄肉部を介して閉塞する閉塞部とが、前記接合部及び前記台座部と一体成形され、
前記閉塞部は、前記台座部側と反対側の面に、前記接合部と反対方向に突出した平板状の把持部を有し、
前記貫通孔の軸線方向からみたときに、前記把持部と前記リブ部とが直交していることを特徴とする。
The male connector of the present invention is
It has a joint part attached to the liquid container and a pedestal part engaging with a female connector connected to the tube, and the liquid contained in the liquid container flows through the joint part and the pedestal part. A male connector provided with a through hole,
On the side of the pedestal portion of the through hole, a cross-shaped rib portion that spans the edge of the through hole, and a thin wall portion that can break the opening defined by the through hole and the rib portion. The closing part to be closed is integrally formed with the joint part and the pedestal part,
The closing portion has a flat plate-like gripping portion protruding in a direction opposite to the joint portion on the surface opposite to the pedestal portion side,
The grip portion and the rib portion are orthogonal to each other when viewed from the axial direction of the through hole.
本発明によれば、雄コネクタの閉塞部が、雄コネクタの他の部位と一体成形されているので、雄コネクタの形成と同時に貫通孔が閉塞された状態になっている。 According to the present invention, since the closed portion of the male connector is integrally formed with other parts of the male connector, the through hole is closed simultaneously with the formation of the male connector.
そのため、貫通孔の閉塞を行うために雄コネクタに対してキャップ部材の取り付けやシール材の貼り付けを行うといった特別の工程が必要ではなくなり、製造工程や材料を減らすことができる。また、その結果、製造コストを抑えることもできる。 This eliminates the need for a special process such as attaching a cap member or attaching a sealing material to the male connector in order to close the through hole, thereby reducing the number of manufacturing processes and materials. As a result, the manufacturing cost can be reduced.
また、使用する直前に閉塞部を破断して分離する構成であるので、使用時に貫通孔の台座部側の開口、すなわち、吐出口の周囲に内容物が付着している状態となっていることを防止することができる。 In addition, since the closed portion is broken and separated immediately before use, the contents are attached around the opening of the through hole on the base portion side, that is, around the discharge port at the time of use. Can be prevented.
閉塞部がこのような把持部を有していれば、使用者がその把持部をつまむことによって、把持部を介して閉塞部と接合部との接続部分に力を加えることができるので、閉塞部の破断・分離を容易に行うことができる。 If the closing portion has such a gripping portion, the user can pinch the gripping portion, so that force can be applied to the connecting portion between the closing portion and the joint portion via the gripping portion. The part can be easily broken and separated.
そして、本発明の雄コネクタは、液体収容体に収容されている液体は、経腸栄養剤又は輸液のいずれか一方であり、雌コネクタに接続されているチューブは、経腸栄養剤を患者に送るための医療用チューブ又は輸液を患者に送るための医療用輸液ラインのいずれか一方であって、医療用チューブ又は医療用輸液ラインのいずれか他方に接続されている雌コネクタが係合不能な形状に形成されていることが好ましい。 In the male connector of the present invention, the liquid contained in the liquid container is either an enteral nutrient or an infusion, and the tube connected to the female connector provides the enteral nutrient to the patient. Either a medical tube for sending or a medical infusion line for sending infusion to a patient, and a female connector connected to either one of the medical tube or medical infusion line cannot be engaged It is preferably formed in a shape.
当該構成により、経腸栄養剤と輸液との誤接続を防止することができる。ここで、係合不能な形状とは、雄コネクタ及び雌コネクタの接続部分の大きさを変えて係合不能とする場合と、雄コネクタ及び雌コネクタの接続部分の形状を異にして係合不能とする場合がある。 With this configuration, it is possible to prevent erroneous connection between the enteral nutrient and the infusion solution. Here, the non-engageable shape means that the size of the connecting part of the male connector and the female connector is changed to be non-engageable, and that the shape of the connecting part of the male connector and the female connector is different, and the non-engageable shape. It may be.
［第１実施形態］
以下、図１〜図３を参照して、本発明の雄コネクタの第１実施形態を説明する。
[First Embodiment]
Hereinafter, with reference to FIGS. 1-3, 1st Embodiment of the male connector of this invention is described.
まず、本実施形態の雄コネクタ１の構成について説明する。 First, the structure of the male connector 1 of this embodiment is demonstrated.
雄コネクタ１は、接合部１ａと、台座部１ｂと、接合部１ａと台座部１ｂとの間に形成されている天板部１ｃとにより構成されている。 The male connector 1 includes a joining portion 1a, a pedestal portion 1b, and a top plate portion 1c formed between the joining portion 1a and the pedestal portion 1b.
接合部１ａには、経腸栄養剤や輸液といった液体が収容された液体収容体であるバッグやボトルが接合される。 A bag or a bottle which is a liquid container in which a liquid such as an enteral nutrient or an infusion is contained is joined to the joint 1a.
台座部１ｂには、経腸栄養療法に用いられる医療用チューブや静脈栄養療法に用いられる輸液ラインといったチューブに接続される不図示の雌コネクタが接続される。そのため、台座部１ｂには、一対の係合爪１ｄが形成されている。また、図２に示すように、台座部１ｂの中央部には、テーパ部１ｅが形成されている。 A female connector (not shown) connected to a tube such as a medical tube used for enteral nutrition therapy or an infusion line used for parenteral nutrition therapy is connected to the pedestal portion 1b. Therefore, a pair of engaging claws 1d is formed on the base portion 1b. Moreover, as shown in FIG. 2, the taper part 1e is formed in the center part of the base part 1b.
係合爪１ｄは、台座部１ｂの端部の周縁から径方向に張り出すように形成されており、不図示の雌コネクタに形成されている係合溝に係合する。 The engaging claw 1d is formed so as to protrude in the radial direction from the peripheral edge of the end portion of the pedestal portion 1b, and engages with an engaging groove formed in a female connector (not shown).
また、テーパ部１ｅは、台座部１ｂから接合部１ａとは反対側の方向に突出した円筒形状であり、その外周面には、雌コネクタに形成されているテーパ面に対応するように、台座部１ｂ方向に向かって縮径する部分が形成されている。 The taper portion 1e has a cylindrical shape that protrudes from the pedestal portion 1b in the direction opposite to the joint portion 1a. The outer peripheral surface of the taper portion 1e corresponds to the taper surface formed on the female connector. A portion that is reduced in diameter toward the portion 1b is formed.
そして、接合部１ａ、台座部１ｂ及び天板部１ｃには、それらを貫通するようにして、それらの中央に貫通孔１ｆが形成されている。 A through hole 1f is formed at the center of the joint portion 1a, the base portion 1b, and the top plate portion 1c so as to penetrate them.
貫通孔１ｆの台座部１ｂ側の開口は、テーパ部１ｅの中央に形成されている。その開口端には、十字形状のリブ部１ｇが形成されている。 The opening on the pedestal portion 1b side of the through hole 1f is formed at the center of the tapered portion 1e. At the opening end, a cross-shaped rib portion 1g is formed.
そして、貫通孔１ｆ、より具体的には、貫通孔１ｆとリブ部１ｇとによって画成される開口を閉塞するように形成された閉塞部１ｈが、貫通孔１ｆの台座部１ｂ側の端部から、接合部１ａとは反対方向に突出するようにして形成されている。閉塞部１ｈは、台座部１ｂ側とは反対側の面に、接合部１ａとは反対方向に突出した把持部１ｉを有している。 The closing portion 1h formed so as to close the through hole 1f, more specifically, the opening defined by the through hole 1f and the rib portion 1g, is the end of the through hole 1f on the side of the base portion 1b. From, it is formed so that it may protrude in the direction opposite to the junction part 1a. The closing part 1h has a grip part 1i protruding in the opposite direction to the joint part 1a on the surface opposite to the pedestal part 1b.
貫通孔１ｆ及びリブ部１ｇと閉塞部１ｈは、図３に示すように、それらの間に形成されている薄肉部１ｊを介して接続されている。 As shown in FIG. 3, the through hole 1f, the rib portion 1g, and the closing portion 1h are connected via a thin portion 1j formed therebetween.
このように形成された雄コネクタ１は、ポリプロピレン（ＰＰ）やポリエチレン（ＰＥ）といった樹脂材料を用いて、一体成形される。 The male connector 1 thus formed is integrally molded using a resin material such as polypropylene (PP) or polyethylene (PE).
なお、この雄コネクタ１には、製造後、プロテクター２が取り付けられることがある。このプロテクター２は、雄コネクタ１が液体収容体に接合されて製造されたプレフィルド型の雄コネクタ付き液体収容体が搬送等されるときに、閉塞部１ｈが意図していない破断・分離をしてしまうことを防止するために取り付けられるものである。 In addition, the protector 2 may be attached to this male connector 1 after manufacture. When the prefilled type liquid container with a male connector manufactured by joining the male connector 1 to the liquid container is transported or the like, the protector 2 breaks and separates the unoccupied portion 1h unintentionally. It is attached in order to prevent it.
次に、本実施形態の雄コネクタ１の台座部１ｂと閉塞部１ｈとの破断・分離、すなわち、開封作業について説明する。 Next, the breaking / separation of the pedestal portion 1b and the closing portion 1h of the male connector 1 of the present embodiment, that is, the opening operation will be described.
雄コネクタ１は、製造された状態では、閉塞部１ｈによって、貫通孔１ｆが閉塞されている（図１（ａ）参照）。そして、このような状態の雄コネクタ１は、接合部１ａを介して、液体を収容している液体収容体に接続され、その液体収容体を密閉する。 In the manufactured state, the male connector 1 has the through hole 1f closed by the closing portion 1h (see FIG. 1A). And the male connector 1 of such a state is connected to the liquid container which contains the liquid via the junction part 1a, and seals the liquid container.
そして、使用時、すなわち、対応する雌コネクタに雄コネクタ１を係合させる際には、把持部１ｉを介して閉塞部１ｈに貫通孔１ｆの中心軸線周りの力を加えれば、閉塞部１ｈ、より具体的には、閉塞部１ｈの縁の薄肉部１ｊが貫通孔１ｆの縁及びリブ部１ｇの縁から捩じ切られて破断し、貫通孔１ｆが開口する。これにより、雄コネクタ１は雌コネクタに係合可能な状態（図１（ｂ）参照）になる。 In use, that is, when the male connector 1 is engaged with the corresponding female connector, if a force around the central axis of the through hole 1f is applied to the closing portion 1h via the grip portion 1i, the closing portion 1h, More specifically, the thin-walled portion 1j at the edge of the closing portion 1h is twisted off from the edge of the through hole 1f and the edge of the rib portion 1g to break, and the through hole 1f is opened. As a result, the male connector 1 becomes engageable with the female connector (see FIG. 1B).
このようにして開封作業が行われた後は、貫通孔１ｆは液体収容体に収容された液体の流路になり、貫通孔１ｆの台座部１ｂ側の開口からはその液体が吐出可能になる。 After the opening operation is performed in this manner, the through hole 1f becomes a flow path for the liquid stored in the liquid container, and the liquid can be discharged from the opening on the base portion 1b side of the through hole 1f. .
なお、閉塞部１ｈと把持部１ｉとを保護するプロテクター２に、閉塞部１ｈ及び把持部１ｉが嵌合する穴部と、テーパ部１ｅに回転可能に係合する係合部とを形成し、プロテクター２を取付けた状態で、プロテクター２ごと閉塞部１ｈと把持部１ｉに力を加えることによって、開封作業を行うことができるようにしてもよい。 The protector 2 that protects the closing portion 1h and the gripping portion 1i is formed with a hole portion into which the closing portion 1h and the gripping portion 1i are fitted, and an engagement portion that is rotatably engaged with the tapered portion 1e. With the protector 2 attached, the opening operation may be performed by applying force to the closing portion 1h and the gripping portion 1i together with the protector 2.
また、閉塞部１ｈに加える力としては、捩じ切るような方向の力に限られるものではなく、閉塞部１ｈを台座部１ｂから切り離すことができるような方向の力であれば、どのような方向の力でもかまわない。 Further, the force applied to the closing portion 1h is not limited to the force in the direction of twisting, and any force can be used as long as the closing portion 1h can be separated from the pedestal portion 1b. The direction force may be used.
本実施形態の雄コネクタ１は、閉塞部１ｈが、雄コネクタ１の他の部位と一体成形されているので、雄コネクタ１の形成と同時に貫通孔１ｆが閉塞された状態になっている。 In the male connector 1 of the present embodiment, the closing portion 1h is integrally formed with other parts of the male connector 1, so that the through hole 1f is closed simultaneously with the formation of the male connector 1.
そのため、貫通孔１ｆの閉塞を行うために雄コネクタ１に対してアルミ薄膜や樹脂薄膜等のシール材の貼り付けを行うといった特別の工程が必要ではなくなり、製造工程や材料を減らすことができる。また、その結果、製造コストを抑えることもできる。 This eliminates the need for a special process of attaching a sealing material such as an aluminum thin film or a resin thin film to the male connector 1 in order to close the through hole 1f, thereby reducing the number of manufacturing processes and materials. As a result, the manufacturing cost can be reduced.
また、本実施形態の雄コネクタ１は、閉塞部１ｈが把持部１ｉを有しているので、閉塞部１ｈを貫通孔１ｆやリブ部１ｇから破断・分離させるための必要な力を、使用者が容易に閉塞部１ｈに加えることができる。
［第２実施形態］
以下、図４〜図５を参照して、本発明の雄コネクタの第２実施形態を説明する。ただし、本実施形態の雄コネクタは、リブ部、閉塞部及び把持部の構成を除き、第１実施形態の雄コネクタと同様の構成であるので、それら以外の部材については同じ符号を付すとともに、詳細な説明は省略する。
Further, in the male connector 1 of the present embodiment, since the closing part 1h has the gripping part 1i, the force necessary for breaking and separating the closing part 1h from the through hole 1f and the rib part 1g is provided to the user. Can be easily added to the closed portion 1h.
[Second Embodiment]
Hereinafter, a second embodiment of the male connector of the present invention will be described with reference to FIGS. However, the male connector of the present embodiment has the same configuration as the male connector of the first embodiment except for the configuration of the rib portion, the blocking portion, and the gripping portion, and therefore, other members are denoted by the same reference numerals, Detailed description is omitted.
本実施形態の雄コネクタ１０においては、貫通孔１ｆの台座部１ｂ側の開口は、テーパ部１ｅの中央に形成されている。その開口端には、十字形状の開口を有するリブ部１０ｇが形成されている。 In the male connector 10 of the present embodiment, the opening on the pedestal portion 1b side of the through hole 1f is formed at the center of the tapered portion 1e. A rib portion 10g having a cross-shaped opening is formed at the opening end.
そして、貫通孔１ｆ、より具体的には、貫通孔１ｆとリブ部１０ｇとによって画成される開口を閉塞するように形成された閉塞部１０ｈが、貫通孔１ｆの台座部１ｂ側の端部から、接合部１ａとは反対方向に突出するようにして形成されている。 The closing portion 10h formed so as to close the through hole 1f, more specifically, the opening defined by the through hole 1f and the rib portion 10g, is the end of the through hole 1f on the base portion 1b side. From, it is formed so that it may protrude in the direction opposite to the junction part 1a.
閉塞部１０ｈは、使用者が指でつまむことができる程度の長さを有しており、第１実施形態の雄コネクタ１が備えている把持部１ｉと同様に、開封作業時に把持する部位としての役割も兼ねている。 The blocking portion 10h has a length that allows the user to pinch it with a finger, and as a gripping portion 1i included in the male connector 1 of the first embodiment, as a portion to be gripped at the time of opening work Also serves as a role.
このように構成された本実施形態の雄コネクタ１０も、上記の第１実施形態の雄コネクタ１と同様の効果を奏する。 The male connector 10 of this embodiment configured as described above also has the same effect as the male connector 1 of the first embodiment.
以上、図示の実施形態について説明したが、本発明はこのような形態に限られるものではない。 Although the illustrated embodiment has been described above, the present invention is not limited to such a form.
上記各実施形態では、液体収容体に収容されている液体が経腸栄養剤である場合と輸液である場合とを併せて説明した。 In each of the above embodiments, the case where the liquid contained in the liquid container is an enteral nutrient and the case where it is an infusion have been described.
しかし、液体収容体に収容されている液体が経腸栄養剤である場合には、雄コネクタ１，１０を、経腸栄養剤を患者に送るための医療用チューブに接続された雌コネクタのみが係合可能な形状とすることが好ましい。 However, when the liquid contained in the liquid container is an enteral nutrient, only the female connectors 1 and 10 are connected to the medical tube for sending the enteral nutrient to the patient. A shape that can be engaged is preferable.
逆に、液体収容体に収容されている液体が輸液である場合には、雄コネクタ１，１０を、輸液を患者に送るための医療用輸液ラインに接続された雌コネクタのみが係合可能な形状とすることが好ましい。 On the contrary, when the liquid accommodated in the liquid container is an infusion, the male connectors 1 and 10 can be engaged only with the female connector connected to the medical infusion line for sending the infusion to the patient. A shape is preferable.
雄コネクタ１，１０をこのように構成すれば、経腸栄養剤と輸液との誤接続を防止することができる。ここで、係合不能な形状とは、雄コネクタ及び雌コネクタの接続部分の大きさを変えて係合不能とする場合と、雄コネクタ及び雌コネクタの接続部分の形状を異にして係合不能とする場合のいずれもが含まれる。 By configuring the male connectors 1 and 10 in this way, it is possible to prevent erroneous connection between the enteral nutrient and the infusion solution. Here, the non-engageable shape means that the size of the connecting part of the male connector and the female connector is changed to be non-engageable, and that the shape of the connecting part of the male connector and the female connector is different, and the non-engageable shape. Are included.
上記実施形態では、雄コネクタ１，１０がリブ部１ｇ，１０ｇを有しているが、本発明の雄コネクタはそのような形態に限られるものではなく、雄コネクタがリブ部を有していなくてもよい。 In the said embodiment, although the male connectors 1 and 10 have the rib parts 1g and 10g, the male connector of this invention is not restricted to such a form, and the male connector does not have a rib part. May be.
また、上記実施形態では、リブ部１ｇ，１０ｇを貫通孔１ｆの開口端に形成している。しかし、本発明の雄コネクタのリブ部は、貫通孔の開口端部に形成されていればよく、例えば、貫通孔の開口端から間隔を存した位置に形成するようにしてもよい。 Moreover, in the said embodiment, the rib parts 1g and 10g are formed in the opening end of the through-hole 1f.
