    • A tubing interface (20) having an elongated tube (21), an elastomeric ferrule (24) and a support ring device (30) disposed around the ferrule (24). The ferrule (24) includes a bore (28) which is sized for receipt of the tube (21). The tubing interface (20) further includes a cap member (31) having an exterior surface (32), an opposed interior surface (33), and a tube receiving passage (35) extending therethrough. The receiving passage (35) is formed and dimensioned for axial sliding receipt of the tube member therethrough. The cap member (31) further includes a cup-shaped receiving recess (36) extending proximally from the interior surface (33), and is formed and dimensioned for axial receipt of the proximal end of the ferrule body member (25) and the support ring (30). When the cap member (31) is mounted to a valve apparatus (29), the support ring (30) and the elastomeric ferrule device (24) compressively cooperate with the cup-shaped recess (36) to form a fluid-tight seal between the tube port (22) and a communication port (45) of the valve apparatus (29).
    • 具有细长管(21),弹性套圈(24)和围绕套圈(24)设置的支撑环装置(30)的管接口(20)。 套圈(24)包括孔(28),孔(28)的尺寸用于容纳管(21)。 管道接口(20)还包括具有外表面(32),相对的内表面(33)和延伸穿过其的管接收通道(35)的盖构件(31)。 接收通道(35)的形状和尺寸用于管件的轴向滑动接收。 盖构件(31)还包括从内表面(33)向近侧延伸的杯状容纳凹部(36),并且形成并定尺寸用于轴套接收套圈本体构件(25)的近端和支撑件 环(30)。 当盖构件(31)安装到阀装置(29)上时,支撑环(30)和弹性套圈装置(24)与杯形凹部(36)压缩配合,以在杯状构件(31)之间形成流体密封, 管口(22)和阀装置(29)的连通口(45)。
