　図１０に示すように、バイアル瓶８００のゴム栓８０５に瓶針９１０を対向させる。図１０において、ゴム栓８０５は、バイアル瓶８００の口８０２に装着されており、これによりバイアル瓶８００は封止されている。ゴム栓８０５が口８０２から外れないように、キャップ８０６が、口８０２及びゴム栓８０５に装着されている。キャップ８０６の中央に開口８０７が形成されており、当該開口８０７内にゴム栓８０５が露出している。 As shown in FIG. 10, the bottle needle 910 is opposed to the rubber stopper 805 of the vial 800. In FIG. 10, the rubber stopper 805 is attached to the mouth 802 of the vial 800, whereby the vial 800 is sealed. A cap 806 is attached to the mouth 802 and the rubber stopper 805 so that the rubber stopper 805 does not come off from the mouth 802. An opening 807 is formed at the center of the cap 806, and the rubber plug 805 is exposed in the opening 807.
　この状態から、瓶針９１０を開口８０７内に露出したゴム栓８０５に突き刺し、バイアル瓶８００に向かって押し込む。瓶針９１０はゴム栓８０５を穿刺し、これを貫通する。 From this state, the bottle needle 910 is pierced into the rubber stopper 805 exposed in the opening 807 and pushed toward the vial 800. The bottle needle 910 punctures the rubber stopper 805 and penetrates it.
　図１１は、瓶針９１０がバイアル瓶８００と連通した状態を示した断面図である。瓶針９１０の周囲に設けられたフード９２０内にバイアル瓶８００のゴム栓８０５及び口８０２が挿入され、フード９２０の内周面に設けられた爪９２２がバイアル瓶８００の口８０２の下側の端縁８０３ｂに係合している。この爪９２２と口８０２との係合が、瓶針９１０がゴム栓８０５から抜けてしまうのを防止する。 FIG. 11 is a cross-sectional view showing a state in which the bottle needle 910 communicates with the vial bottle 800. The rubber stopper 805 and the mouth 802 of the vial 800 are inserted into the hood 920 provided around the bottle needle 910, and the claw 922 provided on the inner peripheral surface of the hood 920 is located below the mouth 802 of the vial 800. It is engaged with the edge 803b. The engagement between the claw 922 and the mouth 802 prevents the bottle needle 910 from coming out of the rubber stopper 805.

　上記の従来のフード９２０のバイアル瓶８００の口８０２に対する着脱は、フード９２０をバイアル瓶８００に対して、瓶針９１０の長手方向に沿って押し引きすることにより行う。爪９２２が口８０２及びゴム栓８０５の外周面上を上下方向に摺動して口８０２及びゴム栓８０５を乗り越えるために、フード９２０を拡径するように弾性変形させる必要がある。フード９２０を拡径させる力は、爪９２２とゴム栓８０５の上側の端縁８０３ａ及び口８０２の下側の端縁８０３ｂとの衝突部分に作用するフード９２０とバイアル瓶８００との間の押し引き力に依存する。このため、フード９２０を口８０２に着脱するために、フード９２０とバイアル瓶８００との間に大きな押し引き力を印加する必要がある。 The above-described conventional hood 920 is attached to and detached from the mouth 802 of the vial 800 by pushing and pulling the hood 920 against the vial 800 along the longitudinal direction of the bottle needle 910. In order for the claw 922 to slide in the vertical direction on the outer peripheral surface of the mouth 802 and the rubber plug 805 and get over the mouth 802 and the rubber plug 805, the hood 920 needs to be elastically deformed to expand the diameter. The force for expanding the diameter of the hood 920 is the pushing and pulling between the hood 920 and the vial 800 acting on the collision portion between the claw 922 and the upper edge 803a of the rubber stopper 805 and the lower edge 803b of the mouth 802. Depends on power. For this reason, in order to attach and detach the hood 920 to and from the mouth 802, it is necessary to apply a large pulling force between the hood 920 and the vial bottle 800.
　フード９２０を口８０２に着脱するために要する力を小さくするためには、フード９２０の剛性を低下させる、爪９２２の突出高さを低くする、などの方法が考えられる。しかしながら、いずれの方法も、爪９２２と口８０２との係合が意図せずに外れてしまい、瓶針９１０がゴム栓８０５から抜けてしまう可能性が高くなる。 In order to reduce the force required to attach / detach the hood 920 to / from the mouth 802, methods such as lowering the rigidity of the hood 920 or lowering the protruding height of the claws 922 are conceivable. However, in any of the methods, the engagement between the claw 922 and the mouth 802 is unintentionally disengaged, and there is a high possibility that the bottle needle 910 is detached from the rubber stopper 805.
　本発明は、メス部材に挿入されたオス部材が意図せずにメス部材から抜けないようにメスコネクタと係合することができ、且つ、メスコネクタに対する着脱作業が容易なオス部材用フードを提供することを目的とする。また、本発明はこのようなオス部材用フードを備えた、安全性と着脱作業性とを両立させたオスコネクタを提供することを目的とする。 The present invention provides a male member hood that can be engaged with a female connector so that the male member inserted into the female member does not unintentionally come out of the female member and can be easily attached to and detached from the female connector. The purpose is to do. Another object of the present invention is to provide a male connector provided with such a male member hood, which has both safety and detachability.
　本発明のオス部材用フードは、メスコネクタに着脱可能なオス部材用フードであって、棒状のオス部材の周囲を取り囲み、前記メスコネクタが挿入される環状部と、前記環状部に、前記オス部材に向かって突出するように設けられた、互いに対向する一対の爪と、前記環状部に設けられた、前記一対の爪が対向する方向と直交する方向に対向する一対の押圧部とを備える。前記一対の押圧部が互いに接近する向きの押力を前記一対の押圧部に印加すると、前記一対の爪が離間するように前記環状部が弾性的に変形する。 The male member hood of the present invention is a male member hood that can be attached to and detached from the female connector. The male member hood surrounds the periphery of the rod-shaped male member, and the male part is inserted into the annular part and the male part. A pair of opposing claws provided to protrude toward the member, and a pair of pressing portions provided in the annular portion and facing in a direction perpendicular to the direction in which the pair of claws oppose . When a pressing force in a direction in which the pair of pressing portions approach each other is applied to the pair of pressing portions, the annular portion is elastically deformed so that the pair of claws are separated from each other.
　本発明のオスコネクタは、棒状のオス部材と、上記の本発明のオス部材用フードとを備える。 The male connector of the present invention includes a rod-shaped male member and the above-described male member hood of the present invention.
　本発明によれば、一対の爪がメスコネクタに係合することにより、メス部材に挿入されたオス部材が意図せずにメス部材から抜けるのを防止することができる。また、一対の押圧部を押圧することにより一対の爪の間隔が拡大するので、メスコネクタに対するフードの着脱が容易である。従って、安全性と着脱作業性とが両立したオスコネクタを提供することができる。 According to the present invention, since the pair of claws engage with the female connector, the male member inserted into the female member can be prevented from unintentionally coming off the female member. Moreover, since the space | interval of a pair of nail | claw is expanded by pressing a pair of press part, attachment / detachment of the food | hood with respect to a female connector is easy. Therefore, it is possible to provide a male connector in which both safety and attachment / detachment workability are compatible.

　本発明のオス部材用フードは、メスコネクタに着脱可能なオス部材用フードであって、棒状のオス部材の周囲を取り囲み、前記メスコネクタが挿入される環状部と、前記環状部に、前記オス部材に向かって突出するように設けられた、互いに対向する一対の爪と、前記環状部に設けられた、前記一対の爪が対向する方向と直交する方向に対向する一対の押圧部とを備える。前記一対の押圧部が互いに接近する向きの押力を前記一対の押圧部に印加すると、前記一対の爪が離間するように前記環状部が弾性的に変形する。 The male member hood of the present invention is a male member hood that can be attached to and detached from the female connector. The male member hood surrounds the periphery of the rod-shaped male member, and the male part is inserted into the annular part and the male part. A pair of opposing claws provided to protrude toward the member, and a pair of pressing portions provided in the annular portion and facing in a direction perpendicular to the direction in which the pair of claws oppose . When a pressing force in a direction in which the pair of pressing portions approach each other is applied to the pair of pressing portions, the annular portion is elastically deformed so that the pair of claws are separated from each other.
　上記の本発明のオス部材用フードにおいて、前記一対の爪が対向する方向に沿った前記環状部の内寸法より、前記一対の押圧部が対向する方向に沿った前記環状部の内寸法が大きいことが好ましい。これにより、円筒形状の外形を有するメスコネクタを環状部に挿入した状態で、一対の押圧部が互いに接近し且つ一対の爪が互いに離間するように弾性変形する環状部を容易に実現することができる。 In the male member hood according to the present invention described above, the inner dimension of the annular part along the direction in which the pair of pressing parts opposes is larger than the inner dimension of the annular part along the direction in which the pair of claws oppose each other. It is preferable. Accordingly, it is possible to easily realize an annular portion that is elastically deformed so that the pair of pressing portions approach each other and the pair of claws are separated from each other with the female connector having a cylindrical outer shape inserted into the annular portion. it can.
　本発明のオス部材用フードは、前記環状部に対してスリットを介して分離された一対の保持板を更に備えることが好ましい。この場合、前記一対の保持板の間に前記メスコネクタが挿入されることが好ましい。これにより、メスコネクタにフードを装着したときのメスコネクタに対するフードの姿勢が矯正される。これは、爪をメスコネクタに安定的に係合させるのに有利である。 It is preferable that the hood for male members of the present invention further includes a pair of holding plates that are separated from the annular portion via a slit. In this case, it is preferable that the female connector is inserted between the pair of holding plates. Accordingly, the posture of the hood with respect to the female connector when the hood is attached to the female connector is corrected. This is advantageous for stably engaging the pawl with the female connector.
　前記メスコネクタに当接することにより前記メスコネクタに対する前記オス部材の挿入深さを規制する当接部を更に備えることが好ましい。これは、メスコネクタに装着されたフードの傾きを低減するのに有利である。また、爪をメスコネクタに安定的に係合させるのに有利である。更に、フード内にメスコネクタを深く挿入しすぎることにより、フードを誤って破損してしまう可能性を低減するのに有利である。 It is preferable to further include an abutting portion that regulates an insertion depth of the male member with respect to the female connector by abutting on the female connector. This is advantageous for reducing the inclination of the hood attached to the female connector. Further, it is advantageous for stably engaging the claw with the female connector. Furthermore, by inserting the female connector too deeply into the hood, it is advantageous to reduce the possibility of the hood being accidentally damaged.
　本発明のオスコネクタは、棒状のオス部材と、上記の本発明のオス部材用フードとを備える。 The male connector of the present invention includes a rod-shaped male member and the above-described male member hood of the present invention.
　前記オス部材が、バイアル瓶のゴム栓に穿刺される瓶針であってもよい。 The bottle member that is pierced into the rubber stopper of the vial may be used as the male member.
　以下に、本発明を好適な実施形態を示しながら詳細に説明する。但し、本発明は以下の実施形態に限定されないことはいうまでもない。以下の説明において参照する各図は、説明の便宜上、本発明の実施形態の構成部材のうち、本発明を説明するために必要な主要部材のみを簡略化して示したものである。従って、本発明は以下の各図に示されていない任意の構成部材を備え得る。また、以下の各図中の部材の寸法は、実際の構成部材の寸法および各部材の寸法比率等を忠実に表したものではない。 Hereinafter, the present invention will be described in detail while showing preferred embodiments. However, it goes without saying that the present invention is not limited to the following embodiments. For convenience of explanation, the drawings referred to in the following description show only the main members necessary for explaining the present invention in a simplified manner among the constituent members of the embodiment of the present invention. Therefore, the present invention can include arbitrary components not shown in the following drawings. In addition, the dimensions of the members in the following drawings do not faithfully represent the actual dimensions of the constituent members and the dimensional ratios of the members.
　図１は、本発明の一実施形態にかかるオス部材用フード（以下、単に「フード」という）２０を示した斜視図である。本実施形態では、オス部材として、バイアル瓶のゴム栓に穿刺される瓶針１０が用いられている。フード２０と瓶針１０とでオスコネクタ１が構成される。図２はフード２０の平面図、図３は瓶針１０の中心軸１０ａを含む面に沿ったフード２０の断面斜視図である。以下の説明の便宜のため、瓶針１０の長手方向（中心軸１０ａ方向）を「上下方向」と呼ぶ。また、上下方向において、基台１９に近い側を「基端側」、遠い側を「先端側」と呼ぶ。 FIG. 1 is a perspective view showing a male member hood (hereinafter simply referred to as “hood”) 20 according to an embodiment of the present invention. In this embodiment, the bottle needle 10 punctured by the rubber stopper of the vial is used as the male member. The male connector 1 is composed of the hood 20 and the bottle needle 10. 2 is a plan view of the hood 20, and FIG. 3 is a cross-sectional perspective view of the hood 20 along a plane including the central axis 10a of the bottle needle 10. As shown in FIG. For convenience of the following description, the longitudinal direction of the bottle needle 10 (the direction of the central axis 10a) is referred to as “vertical direction”. In the vertical direction, the side closer to the base 19 is referred to as “base end side”, and the side far from the base 19 is referred to as “tip side”.
　瓶針１０は、平面視形状が略円形である基台１９の中央から突出した棒状の部材である。瓶針１０は、鋭利な先端１０ｔを形成するために略円錐面（テーパ面）の外面を有する円錐部１５と、円錐部１１と基台１９とを繋ぐ柱状部１６とを備えている。本実施形態では、柱状部１６の外周面は、円錐部１５に近づくにしたがってその外径がわずかに小さくなるテーパ面である。柱状部１６の外周面のテーパ角度は、円錐部１５のテーパ角度より小さい。但し、瓶針１０の外周面の形状は、これに限定されず、任意に構成することができる。例えば、柱状部１６の外周面は、外径が中心軸１０ａ方向において一定である円筒面であってもよい。本実施形態では、柱状部１６の外周面は、テーパ角度が異なる２つのテーパ面で構成されていているが、単一のテーパ面で構成されていてもよく、あるいは、テーパ面及び／又は円筒面を任意に組み合わせて構成されていてもよい。更に、瓶針１０の外周面は、円錐部１５と柱状部１６とが明確に区別されている必要はなく、例えば、先端１０ｔから基台１９に近づくにしたがって外径がなだらかに変化する曲面で構成されていてもよい。 The bottle needle 10 is a rod-shaped member protruding from the center of the base 19 having a substantially circular shape in plan view. The bottle needle 10 includes a conical portion 15 having a substantially conical surface (tapered surface) outer surface and a columnar portion 16 that connects the conical portion 11 and the base 19 in order to form a sharp tip 10t. In the present embodiment, the outer peripheral surface of the columnar portion 16 is a tapered surface whose outer diameter slightly decreases as it approaches the conical portion 15. The taper angle of the outer peripheral surface of the columnar part 16 is smaller than the taper angle of the conical part 15. However, the shape of the outer peripheral surface of the bottle needle 10 is not limited to this, and can be arbitrarily configured. For example, the outer peripheral surface of the columnar portion 16 may be a cylindrical surface whose outer diameter is constant in the direction of the central axis 10a. In the present embodiment, the outer peripheral surface of the columnar portion 16 is configured by two tapered surfaces having different taper angles, but may be configured by a single tapered surface, or may be configured by a tapered surface and / or a cylinder. You may comprise combining the surface arbitrarily. Further, the outer peripheral surface of the bottle needle 10 does not need to be clearly distinguished from the conical portion 15 and the columnar portion 16, and is, for example, a curved surface whose outer diameter gradually changes as it approaches the base 19 from the tip 10t. It may be configured.
　図３に示されているように、瓶針１０内には、中心軸１０ａと略平行な２つの流路１１，１２が互いに独立して形成されている。流路１１は、液体が流れる液体流路であり、流路１２は、気体が流れる気体流路である。液体流路１１は、先端１０ｔ側において、横孔１１ａと連通している。横孔１１ａは、中心軸１０ａに対して直交する方向に沿って延び、柱状部１６の外周面において開口している。気体流路１２は、先端１０ｔ側において、円錐部１５の外周面において開口している。 As shown in FIG. 3, in the bottle needle 10, two flow paths 11 and 12 substantially parallel to the central axis 10a are formed independently of each other. The channel 11 is a liquid channel through which liquid flows, and the channel 12 is a gas channel through which gas flows. The liquid flow path 11 communicates with the lateral hole 11a on the tip 10t side. The lateral hole 11 a extends along a direction orthogonal to the central axis 10 a and opens on the outer peripheral surface of the columnar portion 16. The gas flow path 12 is opened in the outer peripheral surface of the conical part 15 in the front end 10t side.
　基台１９の瓶針１０とは反対側の構成は本発明と直接関係がないため、省略している。基台１９は、例えばバイアル瓶に接続されるコネクタ（図示せず）の一部であってもよい。例えば、特許文献１，２に記載されたコネクタの構成を本実施形態に適用することができる。本実施形態では、液体流路１１及び気体流路１２は、基台１９の下面において開口しているが、それぞれ延長されて所望する流路に連通していてもよい。 The configuration on the opposite side of the base 19 from the bottle needle 10 is not directly related to the present invention, and is therefore omitted. The base 19 may be a part of a connector (not shown) connected to a vial, for example. For example, the structure of the connector described in Patent Documents 1 and 2 can be applied to this embodiment. In the present embodiment, the liquid channel 11 and the gas channel 12 are opened on the lower surface of the base 19, but may be extended to communicate with a desired channel.
　瓶針１０を取り囲むように、フード２０が基台１９から、瓶針１０と同じ側に立設されている。フード２０はその先端側（基台１９から最も遠い側）に、周方向（瓶針１０回りの回転方向）に連続した環状部２１を備える。環状部２１の平面視形状は、略楕円形又は略長円形である。環状部２１の内周面上には一対の爪２２が設けられている。一対の爪２２は、環状部２１の短軸方向に対向している。爪２２は、瓶針１０に向かって突出しており、先端側に傾斜部２２ａを、基端側（基台１９側）に係合部２２ｂを備える。傾斜部２２ａは、基台１９から離れるにしたがって瓶針１０までの距離が拡大するように傾斜した傾斜面である。係合部２２ｂは、瓶針１０の長手方向に直交する面にほぼ沿った平面である。 The hood 20 is erected from the base 19 on the same side as the bottle needle 10 so as to surround the bottle needle 10. The hood 20 includes an annular portion 21 that is continuous in the circumferential direction (rotating direction around the bottle needle 10) on the tip side (the side farthest from the base 19). The planar view shape of the annular portion 21 is a substantially elliptical shape or a substantially oval shape. A pair of claws 22 are provided on the inner peripheral surface of the annular portion 21. The pair of claws 22 are opposed to the short axis direction of the annular portion 21. The claw 22 protrudes toward the bottle needle 10 and includes an inclined portion 22a on the distal end side and an engaging portion 22b on the proximal end side (base 19 side). The inclined portion 22a is an inclined surface that is inclined so that the distance to the bottle needle 10 increases as the distance from the base 19 increases. The engaging portion 22b is a plane substantially along a plane orthogonal to the longitudinal direction of the bottle needle 10.
　一対の爪２２が対向する方向と直交する方向（即ち、環状部２１の長軸方向）に対向して一対の押圧部２３が環状部２１上に設けられている。 A pair of pressing portions 23 are provided on the annular portion 21 so as to be opposed to a direction orthogonal to the direction in which the pair of claws 22 are opposed (that is, the major axis direction of the annular portion 21).
　図２に示されているように、一対の爪２２が対向する方向に沿った環状部２１の内寸法（爪２２を含まない）Ｄ２２より、一対の押圧部２３が対向する方向に沿った環状部２１の内寸法Ｄ２３の方が大きい。内寸法Ｄ２２は、フード２０が適用されるバイアル瓶８００の口８０２及びゴム栓８０５の外径とほぼ同じか、または、これよりわずかに大きい。 As shown in FIG. 2, the inner dimension (excluding the claws 22) D22 of the annular portion 21 along the direction in which the pair of claws 22 face each other, and the annular shape along the direction in which the pair of pressing portions 23 face each other. The inner dimension D23 of the part 21 is larger. The inner dimension D22 is substantially the same as or slightly larger than the outer diameter of the mouth 802 of the vial 800 and the rubber stopper 805 to which the hood 20 is applied.
　環状部２１において、接続部２４が爪２２と押圧部２３とをつないでいる。接続部２４は、環状部２１の短軸方向及び長軸方向に対して傾斜している。 In the annular part 21, the connecting part 24 connects the claw 22 and the pressing part 23. The connecting portion 24 is inclined with respect to the short axis direction and the long axis direction of the annular portion 21.
　環状部２１は、爪２２の近傍から上下方向に延びた４本の支持部材２５を介して、基台１９に固定されている。なお、支持部材２５の数は４本である必要はなく、例えば２本であってもよい。 The annular portion 21 is fixed to the base 19 via four support members 25 extending in the vertical direction from the vicinity of the claw 22. The number of support members 25 need not be four, and may be two, for example.
　環状部２１の一対の押圧部２３と基台１９との間に、一対の保持板２６が基台１９から立設されている。一対の保持板２６は一対の押圧部２３が対向する方向と同じ方向に対向している。略「Ｕ」字状のスリット２７が、保持板２６を、環状部２１及び支持部材２５から分離している。一対の保持板２６の互いに対向する側の面は円筒面であり、その内寸法はフード２０が適用されるバイアル瓶８００の口８０２及びゴム栓８０５の外径にほぼ一致している。保持板２６の瓶針１０と対向する側の面には、上下方向に延びたリブ２８が、瓶針１０に向かって突出している。本例では、リブ２８は、等角度間隔で４本形成されているが、リブ２８の数及び瓶針１０回りの配置位置は、これに限定されない。 A pair of holding plates 26 are erected from the base 19 between the pair of pressing portions 23 of the annular portion 21 and the base 19. The pair of holding plates 26 are opposed in the same direction as the direction in which the pair of pressing portions 23 are opposed. A substantially “U” -shaped slit 27 separates the holding plate 26 from the annular portion 21 and the support member 25. The opposing surfaces of the pair of holding plates 26 are cylindrical surfaces, and the inner dimensions thereof substantially coincide with the outer diameters of the mouth 802 and the rubber stopper 805 of the vial 800 to which the hood 20 is applied. On the surface of the holding plate 26 facing the bottle needle 10, a rib 28 extending in the vertical direction protrudes toward the bottle needle 10. In this example, four ribs 28 are formed at equiangular intervals, but the number of ribs 28 and the arrangement position around the bottle needle 10 are not limited thereto.
　図２に示すように、一対の押圧部２３に、一対の押圧部２３が互いに接近する向きの押力Ｆを印加すると、傾斜した接続部２４が押圧部２３と爪２２とを接続しているために、一対の爪２２が離間するように環状部２１が弾性的に変形する。このとき、環状部２１に接続された支持部材２５も、環状部２１の変形に応じて、その基台１９から遠い側の端部が瓶針１０から離れる向きに弾性的に変形する。一方、保持板２６は、スリット２７により環状部２１及び支持部材２５から分離しているので、環状部２１及び支持部材２５が弾性変形しても、保持板２６はほとんど変形しない。 As shown in FIG. 2, when a pressing force F is applied to the pair of pressing portions 23 such that the pair of pressing portions 23 approach each other, the inclined connecting portion 24 connects the pressing portion 23 and the claw 22. Therefore, the annular portion 21 is elastically deformed so that the pair of claws 22 are separated from each other. At this time, the support member 25 connected to the annular portion 21 is also elastically deformed in such a direction that the end portion far from the base 19 is separated from the bottle needle 10 in accordance with the deformation of the annular portion 21. On the other hand, since the holding plate 26 is separated from the annular portion 21 and the support member 25 by the slit 27, even if the annular portion 21 and the support member 25 are elastically deformed, the holding plate 26 is hardly deformed.
　瓶針１０、基台１９、及びフード２０は、硬質の材料からなることが好ましい。具体的には、ポリアセタール、ポリカーボネート、ポリスチレン、ポリアミド、ポリプロピレン、硬質ポリ塩化ビニル等の樹脂材料を用いて、瓶針１０、基台１９、及びフード２０を一体成形等の方法で作成することができる。 The bottle needle 10, the base 19, and the hood 20 are preferably made of a hard material. Specifically, the bottle needle 10, the base 19, and the hood 20 can be formed by a method such as integral molding using a resin material such as polyacetal, polycarbonate, polystyrene, polyamide, polypropylene, and hard polyvinyl chloride. .
　以上のように構成された本実施形態のフード２０及びこれを備えたオスコネクタ１の使用方法及び作用を説明する。 The usage method and operation of the hood 20 of the present embodiment configured as described above and the male connector 1 having the hood 20 will be described.
　最初に、図４に示すように、バイアル瓶８００のゴム栓８０５に瓶針１０を対向させる。図５Ａ及び図５Ｂは、この状態を示した断面図である。図５Ａの断面は、一対の爪２２を通り、図５Ｂの断面は、一対の押圧部２３を通る。バイアル瓶８００の構成は、図１０に示したものと同じである。 First, as shown in FIG. 4, the bottle needle 10 is made to face the rubber stopper 805 of the vial 800. 5A and 5B are cross-sectional views showing this state. 5A passes through the pair of claws 22, and the cross section of FIG. 5B passes through the pair of pressing portions 23. The configuration of the vial 800 is the same as that shown in FIG.
　このとき、一方の手でバイアル瓶８００を保持し、他方の手でフード２０を保持する。一対の押圧部２３が互いに接近するように２本の指で一対の押圧部２３に押力Ｆを印加し、一対の爪２２の間隔を拡大させる。 At this time, the vial 800 is held with one hand, and the hood 20 is held with the other hand. A pressing force F is applied to the pair of pressing parts 23 with two fingers so that the pair of pressing parts 23 approach each other, and the interval between the pair of claws 22 is expanded.
　この状態から、瓶針１０を開口８０７内に露出したゴム栓８０５に突き刺し、バイアル瓶８００に向かって押し込む。瓶針１０はゴム栓８０５を穿刺し、これを貫通する。これと並行して、バイアル瓶８００のゴム栓８０５及び口８０２が、フード２０の環状部２１内に挿入される。このとき、ゴム栓８０５の上側（フード２０側）の端縁８０３ａが爪２２の傾斜部２２ａに衝突するかも知れない。ところが、上述したように一対の押圧部２３に押力Ｆを印加することにより一対の爪２２の間隔が既に拡大されているので、フード２０にバイアル瓶８００に向かうわずかな押し込み力を更に加えるだけで、一対の爪２２の間隔が拡大するように環状部２１が弾性変形し、爪２２は端縁８０３ａを通過する。 From this state, the bottle needle 10 is pierced into the rubber stopper 805 exposed in the opening 807 and pushed toward the vial 800. The bottle needle 10 punctures the rubber stopper 805 and penetrates it. In parallel with this, the rubber stopper 805 and the mouth 802 of the vial 800 are inserted into the annular portion 21 of the hood 20. At this time, the edge 803a on the upper side (the hood 20 side) of the rubber plug 805 may collide with the inclined portion 22a of the claw 22. However, since the distance between the pair of claws 22 has already been expanded by applying the pressing force F to the pair of pressing portions 23 as described above, only a slight pressing force toward the vial 800 is further applied to the hood 20. Thus, the annular portion 21 is elastically deformed so that the distance between the pair of claws 22 is increased, and the claws 22 pass through the end edge 803a.
　爪２２がバイアル瓶８００の口８０２を乗り越えた後、押圧部２３への押力Ｆをやめると、環状部２１が弾性回復し、爪２２が口８０２より下のくびれ部分８０４に嵌入し、爪２２と口８０２とが係合する。図６は、この状態を示した斜視図、図７Ａ及び図７Ｂはその断面図である。図７Ａ及び図７Ｂの断面は、図５Ａ及び図５Ｂの断面とそれぞれ同じである。一対の保持板２６の間にゴム栓８０５及び口８０２が挿入されている。リブ２８の先端２８ａ（図１、図３を参照）はゴム栓８０５の上面に衝突している。 After the claw 22 gets over the mouth 802 of the vial 800, when the pressing force F to the pressing portion 23 is stopped, the annular portion 21 is elastically recovered, and the claw 22 is fitted into the constricted portion 804 below the mouth 802. 22 and the mouth 802 are engaged. FIG. 6 is a perspective view showing this state, and FIGS. 7A and 7B are sectional views thereof. The cross sections of FIGS. 7A and 7B are the same as the cross sections of FIGS. 5A and 5B, respectively. A rubber plug 805 and a mouth 802 are inserted between the pair of holding plates 26. The tip 28a of the rib 28 (see FIGS. 1 and 3) collides with the upper surface of the rubber stopper 805.
　図７Ａ及び図７Ｂに示されているように、瓶針１０は、ゴム栓８０５を貫通している。瓶針１０の先端１０ｔ側に開口した横孔１１ａと気体流路１２とは、バイアル瓶８００内に露出している。この状態で、液体流路１１及び横孔１１ａを介して、バイアル瓶８００内に液体を流入させることができ、また、バイアル瓶８００内の液体をバイアル瓶８００外に流出させることができる。バイアル瓶８００に対して液体が出入りする際に、気体流路１２を介して空気がバイアル瓶８００に対して出入りする。これにより、バイアル瓶８００内の気圧の変動を低減し、液体の出入りを容易にする。 7A and 7B, the bottle needle 10 passes through the rubber stopper 805. The lateral hole 11a opened to the tip 10t side of the bottle needle 10 and the gas flow path 12 are exposed in the vial 800. In this state, the liquid can be allowed to flow into the vial 800 through the liquid channel 11 and the lateral hole 11a, and the liquid in the vial 800 can be allowed to flow out of the vial 800. When liquid enters and exits the vial 800, air enters and exits the vial 800 through the gas flow path 12. Thereby, the fluctuation | variation of the atmospheric | air pressure in the vial bottle 800 is reduced, and entrance / exit of the liquid is made easy.
　図６、図７Ａ及び図７Ｂの状態において、瓶針１０の液体流路１１及び横孔１１ａを介してバイアル瓶８００に対して液体の出し入れを行った後、フード２０とバイアル瓶８００とを分離する。 In the state of FIG. 6, FIG. 7A and FIG. 7B, the hood 20 and the vial 800 are separated after the liquid is taken in and out of the vial 800 through the liquid flow path 11 and the lateral hole 11a of the bottle needle 10. To do.
　分離は、フード２０とバイアル瓶８００との接続時と同様に、一方の手でバイアル瓶８００を保持し、他方の手でフード２０を保持しながら行う。このとき、一対の押圧部２３が互いに接近するように２本の指で一対の押圧部２３に押力Ｆを印加し、一対の爪２２の間隔を拡大させる。これにより、爪２２と口８０２との係合が解除される。その後、フード２０及びバイアル瓶８００に、互いに引き離す向きの力を印加すればよい。 Separation is performed while holding the vial 800 with one hand and holding the hood 20 with the other hand in the same manner as when the hood 20 and the vial 800 are connected. At this time, a pressing force F is applied to the pair of pressing portions 23 with two fingers so that the pair of pressing portions 23 come close to each other, and the interval between the pair of claws 22 is expanded. Thereby, the engagement between the claw 22 and the mouth 802 is released. Then, what is necessary is just to apply the force of the direction which mutually separates to the food | hood 20 and the vial bottle 800. FIG.
　以上のように、本実施形態によれば、瓶針１０がゴム栓８０５を穿刺した状態で、一対の爪２２がバイアル瓶８００の口８０２に係合する。従って、瓶針１０がゴム栓８０５から意図せずに抜けてしまうのが防止される。 As described above, according to the present embodiment, the pair of claws 22 engage with the mouth 802 of the vial 800 while the bottle needle 10 has punctured the rubber stopper 805. Therefore, the bottle needle 10 is prevented from unintentionally coming out of the rubber stopper 805.
　一対の押圧部２３が互いに接近する向きの押力を一対の押圧部２３に印加すると、一対の爪２２が離間するように環状部２１が弾性的に変形する。従って、瓶針１０をゴム栓８０５に穿刺するとき、及び、ゴム穿８０５に穿刺した瓶針１０をゴム栓８０５から抜き取るとき、一対の押圧部２３を押圧しながらフード２０を保持すると、一対の爪２２の間隔が拡大する。従って、バイアル瓶８００の口８０２に対するフード２０の着脱が容易である。 When a pressing force in a direction in which the pair of pressing portions 23 approach each other is applied to the pair of pressing portions 23, the annular portion 21 is elastically deformed so that the pair of claws 22 are separated. Accordingly, when the bottle needle 10 is punctured into the rubber stopper 805 and when the bottle needle 10 punctured into the rubber stopper 805 is removed from the rubber stopper 805, when the hood 20 is held while pressing the pair of pressing portions 23, a pair of The distance between the claws 22 is increased. Therefore, the hood 20 can be easily attached to and detached from the mouth 802 of the vial 800.
　図９～図１１に示した従来のフード９２０をバイアル瓶８００の口８０２に着脱する際には、フード９２０とバイアル瓶８００との間に印加する押し引き力でフード９２０を弾性的に拡径させなければならない。このため、フード９２０と口８０２との着脱に大きな力が必要であった。 When the conventional hood 920 shown in FIG. 9 to FIG. 11 is attached to and detached from the mouth 802 of the vial 800, the diameter of the hood 920 is elastically expanded by the pushing and pulling force applied between the hood 920 and the vial 800. I have to let it. For this reason, a large force is required to attach and detach the hood 920 and the mouth 802.
　これに対して、本実施形態では、一対の押圧部２３を押圧することにより、一対の爪２２の間隔を拡大させる。従って、一対の押圧部２３に印加した押力Ｆを効率よく一対の爪２２の間隔を拡大させるために使うことができる。その結果、バイアル瓶８００の口８０２に対するフード２０の着脱を相対的に小さな力で行うことができる。 On the other hand, in this embodiment, the space | interval of a pair of nail | claw 22 is expanded by pressing a pair of press part 23. FIG. Therefore, the pressing force F applied to the pair of pressing portions 23 can be used to efficiently increase the distance between the pair of claws 22. As a result, the hood 20 can be attached to and detached from the mouth 802 of the vial 800 with a relatively small force.
　また、これにより爪２２の環状部２１からの突出量を大きくすることができるので、フード２０と口８０２との接続強度が向上する。 Moreover, since the protrusion amount from the annular part 21 of the nail | claw 22 can be enlarged by this, the connection strength of the food | hood 20 and the opening | mouth 802 improves.
　本実施形態では、フード２０とバイアル瓶８００とを分離する際には、一対の押圧部２３を押圧することにより一対の爪２２の間隔を拡大させて爪２２と口８０２との係合を解除する。従って、爪２２の係合部２２ｂ（図３参照）は、爪２２と口８０２との係合の解除の容易性を考慮する必要はなく、瓶針１０の長手方向に直交する面にほぼ沿った平面にすることができる。これにより、フード２０を口８０２に装着した状態で、フード２０及びバイアル瓶８００に、互いに引き離す向きの力が作用しても、爪２２と口８０２との係合は容易には外れない。 In the present embodiment, when the hood 20 and the vial 800 are separated, by pressing the pair of pressing portions 23, the distance between the pair of claws 22 is increased and the engagement between the claws 22 and the mouth 802 is released. To do. Therefore, the engaging portion 22b (see FIG. 3) of the claw 22 does not need to consider the ease of releasing the engagement between the claw 22 and the mouth 802, and is substantially along the plane perpendicular to the longitudinal direction of the bottle needle 10. Can be flat. As a result, even if forces in the direction in which the hood 20 and the vial 800 are separated from each other act on the hood 20 and the vial 800 with the hood 20 attached to the mouth 802, the engagement between the claw 22 and the mouth 802 is not easily disengaged.
　フード２０を口８０２に装着したとき、フード２０の一対の保持板２６間にゴム栓８０５及び口８０２が挿入される。保持板２６は、スリット２７によって環状部２１及び支持部材２５から分離しているので、一対の保持板２６間の間隔は、環状部２１の変形に関わらず一定である。また、基台１９から延びたリブ２８が保持板２６の剛性を向上させる。従って、一対の保持板２６の間にバイアル瓶８００のゴム栓８０５及び口８０２が挿入されることにより、ゴム栓８０５及び口８０２に対するフード２０及び瓶針１０の姿勢が矯正される。これは、爪２２を口８０２に安定的に係合させるのに有利である。 When the hood 20 is attached to the mouth 802, the rubber stopper 805 and the mouth 802 are inserted between the pair of holding plates 26 of the hood 20. Since the holding plate 26 is separated from the annular portion 21 and the support member 25 by the slit 27, the distance between the pair of holding plates 26 is constant regardless of the deformation of the annular portion 21. Further, the rib 28 extending from the base 19 improves the rigidity of the holding plate 26. Therefore, the posture of the hood 20 and the bottle needle 10 with respect to the rubber stopper 805 and the mouth 802 is corrected by inserting the rubber stopper 805 and the mouth 802 of the vial 800 between the pair of holding plates 26. This is advantageous for stably engaging the pawl 22 with the mouth 802.
　更に、リブ２８の先端（当接部）２８ａがゴム栓８０５の上面に衝突することにより、瓶針１０のゴム栓８０５に対する挿入深さを規制することができる。また、ゴム栓８０５に対するフード２０及び瓶針１０の傾きを少なくすることができる。また、リブ２８の先端２８ａと爪２２とでバイアル瓶８００を上下方向（瓶針１０の長手方向）に挟持することができる。これらは、爪２２を口８０２に安定的に係合させるのに有利である。更に、ゴム栓８０５をフード２０内に誤って深く挿入しすぎることにより、フード２０（特に環状部２１）を破損してしまうという誤操作の可能性を低減することができる。 Furthermore, the insertion depth of the bottle needle 10 with respect to the rubber stopper 805 can be restricted by the tip (contact portion) 28a of the rib 28 colliding with the upper surface of the rubber stopper 805. Further, the inclination of the hood 20 and the bottle needle 10 with respect to the rubber stopper 805 can be reduced. In addition, the vial bottle 800 can be sandwiched in the vertical direction (longitudinal direction of the bottle needle 10) by the tip 28a of the rib 28 and the claw 22. These are advantageous for stably engaging the pawl 22 with the mouth 802. Furthermore, if the rubber plug 805 is erroneously inserted too deeply into the hood 20, the possibility of an erroneous operation of damaging the hood 20 (particularly the annular portion 21) can be reduced.
　上記の実施形態は例示に過ぎない。本発明は、上記の実施形態に限定されず、適宜変更することができる。 The above embodiment is merely an example. The present invention is not limited to the above embodiment, and can be modified as appropriate.
　上記の実施形態では、オス部材である瓶針１０に穿刺されるメス部材がゴム栓８０５であり、メス部材を備えたメスコネクタがバイアル瓶８００の口８０２である場合を例に説明したが、本発明のオス部材用カバー及びオスコネクタが適用されるメス部材及びメスコネクタはこれに限定されない。例えば、特許文献３に記載されているように、メス部材が、中央部に直線状のスリット（切り込み）が形成されたゴム等の弾性材料からなる隔壁部材（「セプタム」と呼ばれることがある）であり、メスコネクタが当該隔壁部材を備えたニードルレスポートであってもよい。この場合、オス部材としては、図８に示されているように、外周面が先細のテーパ面又は円筒面であり、中心軸に沿って１本の液体流路３１が形成されたオスルアー３０が用いられる。詳細な説明を省略するが、上記の実施形態と同様に、ニードルレスポートを環状部２１内及び一対の保持板２６間に挿入させ、一対の爪２２をニードルレスポートの外周面に形成された凹部に係合させることができる。オスルアー３０は、隔壁部材のスリットに挿入される。隔壁部材のスリットからオスルアー３０を抜き去るとスリットは直ちに閉じる。 In the above embodiment, the female member pierced into the bottle needle 10 which is a male member is the rubber stopper 805, and the female connector provided with the female member is described as an example, but the mouth 802 of the vial 800 is described as an example. The female member and the female connector to which the male member cover and the male connector of the present invention are applied are not limited thereto. For example, as described in Patent Document 3, the female member is a partition member made of an elastic material such as rubber having a linear slit (cut) at the center (sometimes referred to as a “septum”). The female connector may be a needleless port provided with the partition member. In this case, as shown in FIG. 8, as the male member, there is a male luer 30 whose outer peripheral surface is a tapered surface or a cylindrical surface and in which one liquid channel 31 is formed along the central axis. Used. Although a detailed description is omitted, the needleless port is inserted into the annular portion 21 and between the pair of holding plates 26, and the pair of claws 22 are formed on the outer peripheral surface of the needleless port, as in the above embodiment. It can be engaged with the recess. The male luer 30 is inserted into the slit of the partition member. When the male luer 30 is removed from the slit of the partition member, the slit is immediately closed.
　上記の実施形態ではリブ２８は上下方向に沿って延びていたが、リブの形状はこれに限定されない。例えば、オス部材（瓶針１０）を取り囲むようにフードの内周面に周方向に延びていてもよい。この場合、リブの基台１９とは反対側の面がメスコネクタに当接する当接部となる。あるいは、リブ２８を省略してもよい。 In the above embodiment, the ribs 28 extend in the vertical direction, but the shape of the ribs is not limited to this. For example, you may extend in the circumferential direction on the inner peripheral surface of the hood so as to surround the male member (bottle needle 10). In this case, the surface of the rib opposite to the base 19 is a contact portion that contacts the female connector. Alternatively, the ribs 28 may be omitted.
　保持板２６の数は２つである必要はない。例えば、各保持板２６が、上下方向に延びる直線状のスリットによって２以上に分割されていてもよい。上記の実施形態において、一対の保持板２６を省略して開口させてもよい。 数 The number of holding plates 26 need not be two. For example, each holding plate 26 may be divided into two or more by linear slits extending in the vertical direction. In the above embodiment, the pair of holding plates 26 may be omitted and opened.
　環状部２１の押圧部２３に押力を印加しやすいように押圧部２３の面積を拡大したり、押圧部２３に対する指の滑りを防止するために押圧部２３の外表面に凹凸形状を形成したりしてもよい。 In order to easily apply a pressing force to the pressing portion 23 of the annular portion 21, the surface of the pressing portion 23 is enlarged, or an uneven shape is formed on the outer surface of the pressing portion 23 in order to prevent finger slipping with respect to the pressing portion 23. Or you may.
　環状部２１の平面視形状は、上記の実施形態のように、一対の爪が対向する方向を短軸とし、これと直交する方向を長軸とする略楕円形又は略長円形である必要はなく、例えば、円形、菱形など、任意の形状であってもよい。但し、環状部内にメスコネクタを挿入した状態で一対の押圧部を押圧したときに、一対の押圧部間の間隔が縮小し、一対の爪間の間隔が拡大するように環状部が弾性変形可能なように、自然状態の環状部とメスコネクタとの間に適切な隙間が形成されることが望ましい。 The planar view shape of the annular portion 21 needs to be a substantially elliptical shape or a substantially oval shape having a short axis in a direction in which a pair of claws face each other and a long axis in a direction perpendicular thereto as in the above embodiment. For example, any shape such as a circle or a diamond may be used. However, when the pair of pressing parts is pressed with the female connector inserted into the annular part, the annular part can be elastically deformed so that the distance between the pair of pressing parts is reduced and the distance between the pair of claws is enlarged. Thus, it is desirable that an appropriate gap be formed between the annular portion in the natural state and the female connector.
　本発明は任意のオスコネクタに適用することができる。例えば、バイアル瓶と、薬液バッグと、更にこれらの間で液体を移動させるためのシリンジとが接続されるコネクタ（例えば、特許文献１，２参照）に設けられる、薬液バッグ及び／又はバイアル瓶に接続されるオスコネクタとして本発明を適用することができる。 The present invention can be applied to any male connector. For example, in a chemical solution bag and / or a vial provided in a connector (for example, see Patent Documents 1 and 2) to which a vial, a chemical solution bag, and a syringe for moving a liquid between them are connected. The present invention can be applied as a male connector to be connected.
　本発明の利用分野は特に制限はなく、オス部材をメス部材に挿入した状態を維持するためのロック機構が必要とされる分野において広範囲に利用することができる。特に、医療の分野において、危険な薬液や血液などが漏れ出す可能性があるオス部材とメス部材との接続部分において好ましく利用することができる。但し、医療用途以外の用途、例えば食品用途、一般工業用途などにも利用することができる。 The application field of the present invention is not particularly limited, and can be widely used in fields where a lock mechanism for maintaining the state in which the male member is inserted into the female member is required. In particular, in the medical field, it can be preferably used in a connection portion between a male member and a female member that may leak dangerous chemicals or blood. However, it can also be used for applications other than medical applications, such as food applications and general industrial applications.
