Abstract
Description
螺合の締付けが過剰になると、雄型ルアー部と雌型ルアー部が強く噛みついてしまう。そのため、コネクタの接続解除が必要になった場合に螺合を緩めることができず、他のコネクタと再接続することもできない。また、過剰な締付けトルクにより、雄型ルアー部や雌型ルアー部にひび割れ等の破損が生じることもある。
上記第1接続部分と上記第2接続部分が、互いに螺合する第1螺合部と第2螺合部をそれぞれ有するとともに、この螺合を進めることにより互いに接合する第1シール部と第2シール部をそれぞれ有し、
上記第1シール部と第2シール部の一方は外周がテーパをなす雄型ルアー部であり、他方は内周がテーパをなす雌型ルアー部であり、上記雄型ルアー部の外周と上記雌型ルアー部の内周が接合することにより、上記雄型ルアー部と上記雌型ルアー部との間がシールされる医療用接続構造において、
上記第1接続部分は上記第1螺合部と一体をなす支持部を有し、この支持部の外周に操作筒が取り付けられ、これら第1接続部分の支持部と操作筒との間にトルクリミット機構が設けられ、このトルクリミット機構は、
(ア)上記操作筒を上記第2接続部分に対して螺合緩み方向に回した時には、上記操作筒と一緒に上記第1接続部分の上記支持部が回り、
(イ)上記操作筒を上記第2接続部分に対して螺合進み方向に回す過程において、上記操作筒に付与される回転トルクが所定トルクに達するまで、上記操作筒と一緒に上記第1接続部分の上記支持部が回り、
(ウ)上記操作筒を上記第2接続部分に対して螺合進み方向に回す過程において、上記第1シール部と第2シール部の接合により生じる抵抗を受けて上記操作筒の回転トルクが所定トルクに達した時には、上記操作筒が上記第1接続部分の上記支持部に対して空回りする
ように構成されていることを特徴とする。
上記操作筒を上記第2接続部分に対して螺合緩み方向に回した時には、上記第2係合部の一方側がこれと周方向に対向する上記第1係合部の一方側に係止されることにより、上記操作筒と一緒に上記第1接続部分の上記支持部が回り、
上記操作筒を上記第2接続部分に対して螺合進み方向に回す過程において、上記第2係合部の他方側が上記第1係合部の他方側に係止されることにより、上記操作筒に付与される回転トルクが所定トルクに達するまで、上記操作筒と一緒に上記第1接続部分の上記支持部が回り、
上記操作筒を上記第2接続部分に対して螺合進み方向に回す過程において、上記第1シール部と第2シール部の接合により生じる抵抗を受けて上記操作筒の回転トルクが所定トルクに達した時には、上記第2係合部が上記第1係合部を超えることにより、上記操作筒が空回りする。
上記構成によれば、トルクリミット機構を比較的簡単な構成とすることができる。
上記構成によれば、操作筒を螺合緩み方向に回した時には、第1、第2係合部の係止面同士が当たることにより、確実に第1、第2接続部分の接続を解除できる。また、操作筒を螺合進み方向に回した時には、第1、第2係合部の少なくともいずれか一方の傾斜面の作用により、トルク管理を行うことができる。
上記構成によれば、操作筒の弾性を利用してトルク管理を行うことができ、構成を簡略化できる。また、操作筒が空回りすると、第2係合部が第1係合部を超えてから弾性復帰する時にクリック音が発生するため、所定トルクに達したことを接続作業者に報せることができる。
上記構成によれば、複数の弾性変形部での弾性を利用することにより、トルク管理を行うことができる。
なお、上記操作筒には、U字形状をなす複数のスリットが周方向に等間隔をおいて形成され、これらスリットにより囲われた部位が上記弾性変形部として提供されるようにしてもよい。
他の態様では、上記支持部の上記第1係合部形成領域には、上記第1係合部としての係合凸部が形成され、上記操作筒の上記第2係合部形成領域には、上記第2係合部としての係合凹部が形成され、上記操作筒に回転トルクが付与されない状態において、上記係合凸部が上記係合凹部に収容されている。
上記構成によれば、医療構成要素の通路を塞ぐ閉塞部材の接続作業において、締付けトルクを管理することができる。
図1~図6に示す本発明の第1実施形態に係る医療用接続構造は、薬液や血液等の液体を流すチューブ5、5’(第1、第2の医療構成要素)同士を接続するものである。図1に示すように、この接続構造は、雄型コネクタ1(第1接続部分)と雌型コネクタ2(第2接続部分)とを備えている。
雄型ルアー部材10の外周には、上記連結部11と受部13の境に位置する環状の係合溝12が形成されている。
雄型ルアー部材10は、その中心軸線に沿って貫通する通路15を有している。この通路15がチューブ5の通路と連なっている。
上記螺合部材20を上記雄型ルアー部材10の先端側から軸方向に押し込むと、上記係合凸部21aが雄型ルアー部材10の係合溝12に嵌り、螺合部材20の円筒部21が雄型ルアー部材10の受部13の径方向外側に配されることにより、螺合部材20は雄型ルアー部材10に対して回転可能かつ軸方向に相対移動不能に連結される。この連結状態で、螺合部材20の円筒部22と雄型ルアー部材10の雄型ルアー部14の間には環状の挿入空間が形成されている。
上記円筒部22の内周には雌ねじ部22a(第1螺合部)が形成されている。
上記操作筒30の外周には、指を掛けるための突条35が周方向に等間隔をおいて形成されている。
図3、図4に示すように、螺合部材20の支持部22bの先端部外周は、環状をなす第1係合部形成領域40aとして提供される。この第1係合部形成領域40aには、周方向に等間隔をおいて複数の係合凹部41(第1係合部)が形成されており、隣合う係合凹部41間の部位が円弧面42となっている。
上記螺合部材20の係合凹部41は、その周方向一方側に、上記係合凸部46の係止面46aと周方向に対向する急峻な係止面41aを有し、周方向他方側に緩やかな傾斜面41bを有している。より具体的に説明すると、係止面41a、46aの周方向に対する角度は略90°と大きく、傾斜面41b,46bの周方向に対する角度は、約30~40°と小さい。
上記挿入は、上記雌型コネクタ2の突起2cが雄型コネクタ1の雌ねじ部22aの開口端の歯に当たるまで抵抗なく進められる。
なお、係合凸部46が傾斜面46bを有する場合、係合凹部41は傾斜面を有さなくてもよい。
第1実施形態と同様に、係合凸部47は係止面47aと傾斜面47bを有し、係合凹部48は係止面48aと傾斜面48bを有している。ただし、係止面47aと傾斜面47bは第1実施形態の係止面41a,傾斜面41bとは逆に配置され、係止面48aと傾斜面48bも第1実施形態の係止面46a,傾斜面46bと逆に配置されている。
なお、係合凸部47が傾斜面47bを有していれば、係合凹部48は傾斜面を有さなくてもよい。
雄型コネクタ1Bは、操作筒30を取り付けるための構造を省き、螺合部材20の外周に指掛け部28を加えた点を除き、第1実施形態の雄型コネクタ1と同様の構成を有している。
操作筒30に回転トルクが付与されていない状態では、操作筒30の係合凸部46が雌型コネクタ2Bの係合凹部41に入り込んでいる。
他の2つの流通管部63,63の先端部には雌型ルアー部63a、63aと突起63bが形成されている。
なお、上記流通管部63を第2接続部分として提供し、この流通管部63に第1実施形態と同様の雄型コネクタ1を接続してもよい。
上記流通管部63’に、例えば図19Aに示すチューブ5に固定された雄型コネクタ1Bが接続される。接続作業の際の操作筒30、トルクリミット機構40の作用は第7実施形態と同様であるので説明を省略する。
なお、上記流通管部62’と螺合部材20が協働して、図19Aに示す雄型コネクタ2Bと同様の構成をなす第2接続部分として提供される場合には、図19Aに示す雌型コネクタ2Bが接続される。
アタッチメント75はその基端部に収容凹部76を有し、この収容凹部76には、雌型ルアー部材2Cの先端部の突起2c”が径方向から着脱可能に収容されるようになっている。
なお、上記シリンジ70の液流出部71に、第1実施形態と同様にして螺合部材20および操作筒30、トルクリミット機構40を装着し、この液流出部71に第1実施形態の雌型コネクタ2を接続してもよい、
雌型閉塞部材85(第1接続部分)は、先端側に雌型ルアー部86(第1シール部)を有し、この雌型ルアー部86の先端外周に突起87(第1螺合部)が形成されている。さらに雌型閉塞部材85は、その基端側に操作筒30を取り付けるための支持部88を有している。この操作筒30の取付構造およびトルクリミット機構40は、第7実施形態(図19参照)と同様であるので詳細な説明を省略する。雌型ルアー部86の通路86aは基端側で塞がれている。
図19~図21に示す第7実施形態において、コネクタ1Bの通路15の基端を塞ぐことにより雄型閉塞部材を構成してもよい。
本発明は、チューブ、活栓、シリンジ以外の医療用構成要素での接続構造に適用してもよい。
上記実施形態では、第1接続部分と操作筒は、第1係合部、第2係合部をそれぞれ複数有しているが、それぞれ1つであってもよい。
操作筒の第2接続部分の螺合部に対する回動は相対的なものであり、操作筒を静止させて第2部分の螺合部を回すようにしてもよい。
