Description

第１のステップにおいて、プラグ部４０と、パッチコード４８の第２のコネクタ４６が取り付けられたクランプ部１８とが提供される。そして、ドレープ１４またはソケット２６のような滅菌ドレープがクランプ部１８上に被せられる。次に、先に滅菌されていてもよいプラグ部４０が、ドレープ１４のグロメット３２で補強された穴３０に挿入される。プラグ部４０のキャップ６４は穴３０よりも大きいので、キャップ６４は穴３０を塞ぐ。このようにして、ドレープ１４は、キャップ６４とクランプ部１８との間に密封を形成する。プラグ部４０のキャップ６４は、プラグ部４０を操作するとき、特に、プラグ部をクランプ部１８に挿入したり、クランプ部１８から取り外したりするときにハンドルとして使用され得る。 In a first step, the plug portion 40 and the clamp portion 18 with the second connector 46 of the patch cord 48 attached are provided. A sterile drape, such as drape 14 or socket 26 , is then slipped over clamp portion 18 . The plug portion 40 , which may have been previously sterilized, is then inserted into the grommet 32 reinforced hole 30 of the drape 14 . Since cap 64 of plug portion 40 is larger than hole 30 , cap 64 closes hole 30 . In this manner, drape 14 forms a seal between cap 64 and clamp portion 18 . The cap 64 of the plug portion 40 may be used as a handle when manipulating the plug portion 40 , particularly when inserting and removing the plug portion from the clamp portion 18 .
