Description

本発明は、例えば、医療用輸液ラインなどに用いられるコネクタであって、オスコネクタが差し込み可能なメスコネクタに関する。 The present invention relates to, for example, a connector used in a medical infusion line or the like, and a female connector into which a male connector can be inserted.

従来、例えば、医療用輸液ラインなどに用いられるコネクタであって、オスコネクタが差し込み可能なメスコネクタが知られている（例えば、特許文献１参照）。 Conventionally, a female connector into which a male connector can be inserted is known as a connector used for, for example, a medical infusion line (see, for example, Patent Document 1).

実開平２−４５７５９号公報Jikkenhei 2-45759 Gazette

メスコネクタには、オスコネクタが差し込まれた状態で意図せずにオスコネクタが脱落することを防止すべく、メスコネクタの差し込み口の開口端縁からオスコネクタの外周に沿って連結部を伸ばし、連結部の先端にオスコネクタの外周に設けられた凸部と係合する係合部を設けることが考えられる。 In order to prevent the male connector from accidentally falling off when the male connector is inserted into the female connector, a connecting portion is extended from the opening edge of the female connector insertion port along the outer circumference of the male connector. It is conceivable to provide an engaging portion that engages with the convex portion provided on the outer periphery of the male connector at the tip of the connecting portion.

しかしながら、メスコネクタの開口端縁から連結部を伸ばすため、メスコネクタが比較的大きくなり、メスコネクタが患者と接触したときに、患者に不快感を与える虞がある。 However, since the connecting portion extends from the open end edge of the female connector, the female connector becomes relatively large, and when the female connector comes into contact with the patient, there is a risk of causing discomfort to the patient.

本発明は、以上の点に鑑み、比較的短くすることができるメスコネクタを提供することを目的とする。 In view of the above points, it is an object of the present invention to provide a female connector that can be made relatively short.

［１］上記目的を達成するため、本発明は、
オスコネクタ（例えば、実施形態のオスコネクタ８。以下同一。）が開口部（例えば、実施形態の開口部２ａ。以下同一。）から差し込まれて前記オスコネクタと接続可能な筒状のメスコネクタ本体（例えば、実施形態のメスコネクタ本体２。以下同一。）を備えるメスコネクタ（例えば、実施形態のメスコネクタ１。以下同一。）であって、
前記メスコネクタ本体の外面には、前記開口部側の端縁に対して前記メスコネクタ本体の軸方向へ間隔を存した位置から前記開口部側に向かって延びる連結部（例えば、実施形態の連結部３。以下同一。）が設けられ、
前記連結部の前記オスコネクタ側には、前記オスコネクタと解除自在に係合可能な係合部（例えば、実施形態の爪部５。以下同一。）が設けられていることを特徴とする。 [1] In order to achieve the above object, the present invention
A tubular female connector body in which a male connector (for example, the male connector 8 of the embodiment; the same applies hereinafter) is inserted through an opening (for example, the opening 2a of the embodiment; the same applies hereinafter) and can be connected to the male connector. (For example, the female connector main body 2 of the embodiment; the same applies hereinafter) is provided (for example, the female connector 1 of the embodiment; the same applies hereinafter).
On the outer surface of the female connector main body, a connecting portion extending toward the opening side from a position where there is an axial distance of the female connector main body with respect to the edge on the opening side (for example, the connection of the embodiment). Part 3. The same shall apply hereinafter.)
The male connector side of the connecting portion is provided with an engaging portion (for example, the claw portion 5 of the embodiment; the same applies hereinafter) that can be disengaged from the male connector.

本発明によれば、従来品の如く、メスコネクタの差し込み口の開口端縁からオスコネクタの外周に沿って連結部が延びておらず、開口部側の端縁から間隔を存した位置から開口部側に向かって連結部が延びているため、軸方向の長さを従来よりも短くすることができる。これにより、患者へ与える不快感を抑制することができる。 According to the present invention, unlike the conventional product, the connecting portion does not extend from the opening edge of the female connector insertion port along the outer periphery of the male connector, and the opening is opened from a position where there is a gap from the edge on the opening side. Since the connecting portion extends toward the portion side, the length in the axial direction can be made shorter than before. As a result, the discomfort given to the patient can be suppressed.

［２］また、本発明においては、連結部には、環状部（例えば、実施形態の環状部４。以下同一。）が設けられ、前記係合部は前記環状部を介して前記連結部に設けられており、前記環状部の周方向において、前記係合部の前記環状部に接続する位置と前記連結部の前記環状部に接続する位置とが異なることが好ましい。 [2] Further, in the present invention, the connecting portion is provided with an annular portion (for example, the annular portion 4 of the embodiment; the same applies hereinafter), and the engaging portion is attached to the connecting portion via the annular portion. It is preferable that the position of the engaging portion connected to the annular portion and the position of the connecting portion connected to the annular portion are different in the circumferential direction of the annular portion.

かかる構成によれば、環状部に対して係合部と連結部の位置とが異なるため、容易に連結部と環状部との接続部分を押圧することにより、容易に係合部の係合を解除させることができる。 According to this configuration, since the positions of the engaging portion and the connecting portion are different with respect to the annular portion, the engaging portion can be easily engaged by easily pressing the connecting portion between the connecting portion and the annular portion. It can be released.

［３］また、本発明においては、前記環状部には、前記オスコネクタが前記メスコネクタ本体に差し込まれて前記係合部と係合している状態で、前記メスコネクタ本体に対する前記オスコネクタの相対的な回転を阻止する回り止め部（例えば、実施形態の当接部６。以下同一。）が設けられていることが好ましい。 [3] Further, in the present invention, in the annular portion, the male connector is inserted into the female connector main body and engaged with the engaging portion, and the male connector with respect to the female connector main body is provided. It is preferable that a detent portion (for example, the contact portion 6 of the embodiment; the same applies hereinafter) is provided to prevent relative rotation.

かかる構成によれば、オスコネクタとメスコネクタとが相対的に回転することにより、係合部の係合状態が解除されることを防止することができる。 According to such a configuration, it is possible to prevent the engagement state of the engaging portion from being released by the relative rotation of the male connector and the female connector.

［４］また、本発明においては、前記メスコネクタ本体の内周面には、複数の種類のテーパ部（例えば、実施形態のテーパ部７ａ〜７ｃ。以下同一。）が設けられていることが好ましい。 [4] Further, in the present invention, the inner peripheral surface of the female connector main body is provided with a plurality of types of tapered portions (for example, tapered portions 7a to 7c of the embodiment; the same applies hereinafter). preferable.

かかる構成によれば、複数種類のテーパ部を備えるオスコネクタと接続可能となり、メスコネクタの汎用性を向上させることができる。 According to such a configuration, it becomes possible to connect to a male connector having a plurality of types of tapered portions, and the versatility of the female connector can be improved.

［５］また、本発明においては、前記環状部には、前記係合部と係合する前記オスコネクタの被係合部（例えば、実施形態のフランジ１０、フック部１１。以下同一。）とが係合できない状態での前記被係合部の前記環状部内への侵入を阻止する阻止部（例えば、実施形態のリブ９。以下同一。）が設けられていることが好ましい。 [5] Further, in the present invention, the annular portion has the engaged portion of the male connector that engages with the engaging portion (for example, the flange 10 and the hook portion 11 of the embodiment; the same applies hereinafter). It is preferable that a blocking portion (for example, the rib 9 of the embodiment; the same applies hereinafter) is provided to prevent the engaged portion from entering the annular portion in a state where the engaged portion cannot be engaged.

かかる構成によれば、係合部と被係合部の位置がずれた状態でオスコネクタをメスコネクタに接続しようとしても、被係合部が阻止部に引っ掛かって接続を阻止することができる。これにより、メスコネクタにオスコネクタを誤った状態で接続することを防止することができる。 According to such a configuration, even if an attempt is made to connect the male connector to the female connector in a state where the engaged portion and the engaged portion are misaligned, the engaged portion can be caught by the blocking portion and the connection can be blocked. This makes it possible to prevent the male connector from being connected to the female connector in an erroneous state.

本発明の実施の形態を図１から図９を参照して説明する。 Embodiments of the present invention will be described with reference to FIGS. 1 to 9.

図１に示すように、本実施形態のメスコネクタ１は、円筒状のメスコネクタ本体２と、メスコネクタ本体２の外周面に設けられた一対の連結部３，３と、を備えている。図２は、メスコネクタ１の側面図である。 As shown in FIG. 1, the female connector 1 of the present embodiment includes a cylindrical female connector main body 2 and a pair of connecting portions 3 and 3 provided on the outer peripheral surface of the female connector main body 2. FIG. 2 is a side view of the female connector 1.

図３の平面図を参照して、メスコネクタ本体２は、オスコネクタが差し込み可能な開口部２ａを備えている。図４はメスコネクタ１の底面図、図５は図３のＶ−Ｖ線切断断面図、図６は図３のＶＩ−ＶＩ線切断断面図である。 With reference to the plan view of FIG. 3, the female connector main body 2 includes an opening 2a into which a male connector can be inserted. FIG. 4 is a bottom view of the female connector 1, FIG. 5 is a VV line cut sectional view of FIG. 3, and FIG. 6 is a VI-VI line cut sectional view of FIG.

一対の連結部３，３は、メスコネクタ本体２の外周面であって、開口部２ａ側の端縁に対してメスコネクタ本体２の軸方向へ間隔を存した位置に接続されており、開口部２ａに差し込まれるオスコネクタ側に向かって延びている。 The pair of connecting portions 3 and 3 are connected to the outer peripheral surface of the female connector main body 2 at a position where there is an axial distance between the female connector main body 2 and the edge on the opening 2a side. It extends toward the male connector side to be inserted into the portion 2a.

連結部３の先端には、メスコネクタ本体２と同心の環状部４が設けられている。環状部４の内周面には、連結部３，３の接続位置から９０度ずれた位置に径方向内側へ突出する一対の爪部５，５が設けられている。本実施形態においては、この一対の爪部５，５が本発明の係合部に該当する。 An annular portion 4 concentric with the female connector main body 2 is provided at the tip of the connecting portion 3. On the inner peripheral surface of the annular portion 4, a pair of claw portions 5 and 5 protruding inward in the radial direction are provided at positions deviated by 90 degrees from the connection positions of the connecting portions 3 and 3. In the present embodiment, the pair of claw portions 5 and 5 correspond to the engaging portions of the present invention.

図７に示すように、連結部３，３は押圧し易いように幅広に形成されており、連結部３，３を押圧することにより、環状部４が楕円形状に変形して、爪部５，５のオスコネクタとの係合が解除されるように構成されている。 As shown in FIG. 7, the connecting portions 3 and 3 are formed wide so as to be easily pressed, and by pressing the connecting portions 3 and 3, the annular portion 4 is deformed into an elliptical shape and the claw portion 5 is formed. , 5 are configured to be disengaged from the male connector.

また、環状材４の内周面には、メスコネクタ本体２の開口部２ａに差し込まれたオスコネクタがメスコネクタ本体２に対して相対的に回転することを阻止すべく、オスコネクタのフランジなどに周方向から当接可能な当接部６が径方向内方に突出して設けられている。 Further, on the inner peripheral surface of the annular member 4, a flange of the male connector or the like is provided so as to prevent the male connector inserted into the opening 2a of the female connector main body 2 from rotating relative to the female connector main body 2. A contact portion 6 that can be contacted from the circumferential direction is provided so as to project inward in the radial direction.

メスコネクタ本体２の内周面には、テーパ部７が設けられている。テーパ部７は、それぞれ傾斜角度の異なる３種類の第１テーパ部７ａ、第２テーパ部７ｂ、第３テーパ部７ｃで構成されている。第１から第３のテーパ部７ａ〜７ｃのうち何れか１つをルアーテーパ部（１００ｍｍあたり直径が６ｍｍ小さくなるテーパ部。６／１００テーパ部。）としてもよい。 A tapered portion 7 is provided on the inner peripheral surface of the female connector main body 2. The tapered portion 7 is composed of three types of first tapered portions 7a, second tapered portions 7b, and third tapered portions 7c, each having a different inclination angle. Any one of the first to third tapered portions 7a to 7c may be used as a luer tapered portion (a tapered portion whose diameter is reduced by 6 mm per 100 mm. A 6/100 tapered portion).

図８Ａ〜図８Ｅは、様々な種類のオスコネクタ８を示している。図９Ａ〜図９Ｅは、図８Ａ〜図８Ｅのオスコネクタ８をメスコネクタ本体２に差し込んだ状態を示している。このように、本実施形態のメスコネクタ１は、３種類のテーパ部７ａ〜７ｃを備えるため、様々なオスコネクタ８との接続が可能となり、メスコネクタ１の汎用性が向上される。 8A-8E show various types of male connectors 8. 9A to 9E show a state in which the male connector 8 of FIGS. 8A to 8E is inserted into the female connector main body 2. As described above, since the female connector 1 of the present embodiment includes three types of tapered portions 7a to 7c, it is possible to connect to various male connectors 8 and the versatility of the female connector 1 is improved.

また、図９Ａ〜図９Ｅから、メスコネクタ本体２に差し込まれたオスコネクタ８が意図せずに脱落することを阻止すべく爪部５がオスコネクタ８にしっかりと係合していることが分かる。また、メスコネクタ本体２に差し込まれたオスコネクタ８は、そのフランジなどが周方向から当接部に接触するため、オスコネクタ８とメスコネクタ本体２との相対回転が阻止され、爪部５とオスコネクタ８とが意図せずに解除されることを防止している。 Further, from FIGS. 9A to 9E, it can be seen that the claw portion 5 is firmly engaged with the male connector 8 in order to prevent the male connector 8 inserted into the female connector main body 2 from being unintentionally dropped off. .. Further, since the male connector 8 inserted into the female connector main body 2 comes into contact with the abutting portion from the circumferential direction, the relative rotation between the male connector 8 and the female connector main body 2 is prevented, and the claw portion 5 and the male connector 8 are prevented from rotating. It prevents the male connector 8 from being unintentionally released.

本実施形態のメスコネクタ１によれば、従来品の如く、メスコネクタの差し込み口の開口端縁からオスコネクタの外周に沿って連結部が延びておらず、開口部２ａ側の端縁から間隔を存した位置から開口部２ａからメスコネクタ本体２に差し込まれるオスコネクタ側に向かって連結部３が延びている。このため、メスコネクタ１の軸方向の長さを従来よりも短くすることができ、メスコネクタ１が患者に接触しても、患者へ与える不快感を抑制することができる。 According to the female connector 1 of the present embodiment, unlike the conventional product, the connecting portion does not extend from the opening edge of the female connector insertion port along the outer periphery of the male connector, and is spaced from the edge on the opening 2a side. The connecting portion 3 extends from the opening 2a toward the male connector side to be inserted into the female connector main body 2. Therefore, the axial length of the female connector 1 can be made shorter than before, and even if the female connector 1 comes into contact with the patient, the discomfort given to the patient can be suppressed.

また、本実施形態のメスコネクタ１によれば、環状部４に対して爪部５，５と連結部３，３との接続位置が９０度異なる。 Further, according to the female connector 1 of the present embodiment, the connection positions of the claw portions 5 and 5 and the connecting portions 3 and 3 are different by 90 degrees with respect to the annular portion 4.

ここで、爪部５，５が連結部３，３と環状部４の周方向において同じ位置に設けられている場合、爪部５，５のオスコネクタ８との係合を解除するためには、爪部５，５及び連結部３，３が接続された環状部４の部分に対して９０度周方向にずれた部分の環状部４を径方向内側へ押圧することにより、爪部５，５の解除操作が行われることとなる。しかしながら、連結部３，３が接続された環状部４の部分は連結部３，３の存在により剛性が比較的高くなってしまうため、爪部５，５を解除し難い。 Here, when the claw portions 5 and 5 are provided at the same positions in the circumferential direction of the connecting portions 3 and 3 and the annular portion 4, in order to disengage the claw portions 5 and 5 from the male connector 8. By pressing the annular portion 4 of the portion displaced 90 degrees in the circumferential direction with respect to the portion of the annular portion 4 to which the claw portions 5, 5 and the connecting portions 3, 3 are connected, the claw portions 5, The release operation of 5 will be performed. However, it is difficult to release the claw portions 5 and 5 because the portion of the annular portion 4 to which the connecting portions 3 and 3 are connected has a relatively high rigidity due to the presence of the connecting portions 3 and 3.

そこで、本実施形態のメスコネクタ１では、環状部４に対して爪部５，５と連結部３，３との接続位置を９０度異ならせることにより、爪部５，５が設けられた環状部４の部分が径方向外方へ比較的変形し易くなり、連結部３，３と環状部４との接続部分を押圧することにより、爪部５とオスコネクタ８との係合を容易に解除させることができる。 Therefore, in the female connector 1 of the present embodiment, the claw portions 5, 5 are provided by making the connection positions of the claw portions 5, 5 and the connecting portions 3, 3 different by 90 degrees with respect to the annular portion 4. The portion of the portion 4 is relatively easily deformed outward in the radial direction, and by pressing the connecting portion between the connecting portions 3 and 3 and the annular portion 4, the claw portion 5 and the male connector 8 can be easily engaged with each other. It can be released.

なお、本実施形態においては、メスコネクタ本体２の内周面に３種類のテーパ部７ａ〜７ｃを備えるテーパ部７を説明したが、本発明のテーパ部は、３種類に限らず、１種類でも、２種類でも、４種類以上であってもよい。 In the present embodiment, the tapered portion 7 having three types of tapered portions 7a to 7c on the inner peripheral surface of the female connector main body 2 has been described, but the tapered portion of the present invention is not limited to three types but one type. However, it may be two types or four or more types.

また、環状部４は無くてもよい。この場合、爪部５は、例えば、連結部３の先端にもうけ、連結部３を径方向外側へ引っ張ることにより爪部５を解除するように構成してもよい。 Further, the annular portion 4 may be omitted. In this case, the claw portion 5 may be provided, for example, at the tip of the connecting portion 3 and may be configured to release the claw portion 5 by pulling the connecting portion 3 radially outward.

また、本実施形態の環状部４の内周面には、連結部３に対応する部分に位置させて径方向内方へ延びるリブ９が設けられている。これにより、爪部５と係合するオスコネクタ８の部分（例えば、フランジ１０）を誤って爪部５が存在しない連結部３に対応する位置でオスコネクタ８とメスコネクタ１とを接続しようとしても、リブ９にオスコネクタ８の爪部５と係合する部分（例えば、フランジ１０）が引っ掛かって接続が阻止される。従って、オスコネクタ８とメスコネクタ１との誤った接続をリブ９で阻止することができる。 Further, on the inner peripheral surface of the annular portion 4 of the present embodiment, a rib 9 located at a portion corresponding to the connecting portion 3 and extending inward in the radial direction is provided. As a result, an attempt is made to connect the male connector 8 and the female connector 1 at a position corresponding to the connecting portion 3 in which the claw portion 5 does not exist by mistakenly connecting the portion of the male connector 8 (for example, the flange 10) that engages with the claw portion 5. Also, a portion (for example, a flange 10) that engages with the claw portion 5 of the male connector 8 is caught by the rib 9, and the connection is blocked. Therefore, the rib 9 can prevent an erroneous connection between the male connector 8 and the female connector 1.

なお、被係合部としてフランジ１０を例示したが、本発明の被係合部はこれに限らず、他のものであってもよい。例えば、図８Ａ、図８Ｂ、図９Ａ、図９Ｂに示すようなフック部１１であってもよい。また、阻止部としてリブ９を用いて説明したが、本発明の阻止部はこれに限らず、他のものであってもよい。 Although the flange 10 has been illustrated as the engaged portion, the engaged portion of the present invention is not limited to this, and may be another one. For example, the hook portion 11 as shown in FIGS. 8A, 8B, 9A, and 9B may be used. Further, although the rib 9 has been described as the blocking portion, the blocking portion of the present invention is not limited to this, and may be another one.
