Abstract: A valve (1) suitable for use on an indwelling catheter is disclosed. Broadly the valve (1) comprises a valve housing (2) having an elongate valve insert (3) disposed therein. The housing (2) has an inlet (4) at one end thereof and an outlet (5) at an opposed end thereof and defines a longitudinal passage (7) extending from the inlet (4) to the outlet (5). The valve insert (3) includes a cannula (25) having an inlet (26) towards one end (27) thereof and an outlet (28) towards an opposed end (29) thereof. The inlet end (27) of the cannula (25) terminates in a sharp point. The outlet end (29) by contrast is rounded and the actual outlet (28) is spaced axially inwardly from the end (29). The valve insert (3) further includes a seal (40) comprising an annular body (41) of resilient material defining an opening (42) therein through which the outlet end (29) of the cannula (25) projects. The seal (40) has an axial end surface which sealingly engages a seat (19) defined by the housing (2). The cannula (25) is displaceable in the housing (2) between a closed position in which the outlet (28) is upstream of the seal (40) and an open position in which the outlet (28) is downstream of the seal (40). The valve insert (3) further includes biasing means in the form of a resilient sleeve (50) loaded under compression for urging the cannula (25) to the closed position. The compression loading in the sleeve (50) also urges the seal (40) into engagement with the seat (19). Typically the valve insert (3) also includes a further sleeve (60) for extending over and around the inlet of the cannula (25). In use the sleeve (60) is punctured by the sharp point on the end (27) of the cannula (25).

Abstract translation: 公开了一种适用于留置导管的阀门（1）。 广义上，阀（1）包括具有设置在其中的细长阀插入件（3）的阀壳体（2）。 壳体（2）在其一端具有入口（4）和在其相对端处的出口（5），并且限定从入口（4）延伸到出口（5）的纵向通道（7）。 阀插入件（3）包括具有朝向其一端（27）的入口（26）和朝向其相对端（29）的出口（28）的套管（25）。 套管（25）的入口端（27）终止于尖锐点。 相反，出口端（29）是圆形的，并且实际出口（28）从端部（29）轴向向内间隔开。 阀插入件（3）还包括密封件（40），该密封件包括限定开口（42）的弹性材料的环形体（41），套管（25）的出口端（29）穿过该开口突出。 密封件（40）具有密封地接合由壳体（2）限定的座（19）的轴向端表面。 套管（25）可在壳体（2）中位于关闭位置之间，在该关闭位置，出口（28）位于密封件（40）的上游，而打开位置，出口（28）位于密封件（40）的下游 ）。 阀插入件（3）还包括呈压缩状态的弹性套筒（50）形式的偏压装置，以将套管（25）推到关闭位置。 套筒（50）中的压缩载荷也促使密封件（40）与座椅（19）接合。 通常，阀插入件（3）还包括另外的套筒（60），用于在套管（25）的入口上方延伸。 在使用中，套管（60）被插管（25）的端部（27）上的尖锐部分刺穿。

Abstract: A reservoir module (50) which is connected to a peristaltic pump to administer carefully metered quantities of medicament to a patient is disclosed. The reservoir module (50) comprises broadly two connector assemblies (1) and two vials (5). Each connector assembly (1) comprises a support member (2), an adaptor (3) for attaching to a vial (5), and a vial cover (4). The adaptor (3) defines a flow path therethrough which places medicament within the vial in fluid communication with the suction conduit of a pump. The vial cover (4) encloses and receives the adaptor (3) and vial (5) and holds them securely to the support member (2). Apparatus for administering medicament to a patient in need thereof including a reservoir module as described above in combination with a peristaltic pump is also disclosed.
