摘要： A connector is provided for securing a conduit to a fluid source, which source includes a noncircular cylindrical pedestal having a fluid source outlet extending therethrough and an annular groove surrounding the pedestal. The connector includes an inlet port engageable with the fluid source outlet and an outlet port in fluid communication with the inlet port and engageable with the conduit. A collet includes a base, and a plurality of fingers extending from the base substantially parallel to an axis of the inlet port, each finger being disposed a common radial distance from the axis of the inlet port and including a radially extending pawl spaced from the base. An annular cam has a noncircular cylindrical receptacle correspondingly engageable with the noncircular cylindrical pedestal of the fluid source and having an axis coincident with the axis of the inlet port. The cam is seated within the collet and disposed to rotate about the coincident axes, so that when the pedestal is engaged with the receptacle, rotation of the pedestal causes the cam to rotate. The cam includes a contact surface which, when the cam is rotated by rotation of the pedestal, abuts the fingers of the collet and forces the pawls away from the coincident axes into the annular groove to secure the conduit to the fluid source.
摘要翻译：提供了一种用于将导管固定到流体源的连接器，该源包括具有延伸穿过其中的流体源出口的非圆形圆柱形基座和围绕基座的环形槽。连接器包括可与流体源出口接合的入口端口和与入口端口流体连通并可与导管接合的出口端口。夹头包括基部和从基部延伸的多个指状物，基本上平行于入口端口的轴线，每个指状物设置成与入口端口的轴线共同的径向距离，并且包括与基部间隔开的径向延伸的棘爪。环形凸轮具有非圆形圆筒形容器，其可与流体源的非圆形圆柱形基座相配合并且具有与入口端轴线重合的轴线。凸轮位于夹头内并且设置成围绕重合的轴线旋转，使得当基座与插座接合时，基座的旋转使凸轮旋转。凸轮包括接触表面，当凸轮通过基座的旋转而旋转时，该接触表面邻接夹头的指状物并迫使该爪离开重合的轴线进入环形槽，以将导管固定到流体源。
