Abstract
【解決手段】本体は第1及び第2の内腔を画成する。第1内腔は、基端をシールするように押圧された第1バルブを含む第1アダプタを有する。第1内腔は第1横ポートを画成し、第2内腔は第2横ポートを画成する。プッシュロッドが第1バルブに連結されている。これは、プッシュロッドが第1バルブを対応して移動するためである。プッシュロッドはチップまで延びている。チップは、第1内腔内に延びる第1部材及び第2内腔内に延びる第2部材を含み、チップが閉鎖位置にあるとき、第1部材が第1横ポートをシールし、第2部材が第2横ポートをシールする。第1バルブは、第1内腔の基端と第1内腔との間を流体連通するように係合でき、第1及び第2の部材が開放位置に移動すると、流体連通が確立される。第1及び第2の内腔は同軸であってもよく、これによって、第1内腔は、第2内腔の第2ポートをシールする第1ポートを有する。
