    • A drug infusion manifold for controlling the infusion of drugs and/or other solutions into an intravenous patient feed line. The manifold includes a housing defining an elongated in-line flow channel that communicates at one end with a carrier fluid inlet line and at the other end with the patient feed line. A plurality of spaced apart drug inlet openings are formed in the housing in communication with the flow channel. Each of the inlet openings is provided with a check valve assembly that includes a valve member defining an inlet socket portion and a valve stem portion that extends into the flow channel. The valve stem portion has a cylindrical side wall that defines an inlet passage that communicates with the socket portion. A plurality of lateral inlet ports extend through the side wall. An elastic sleeve member is received about the valve stem portion in covering relationship with the inlet ports. The valve stem portion is in-line with the flow of carrier fluid through the flow channel.
    • 用于控制将药物和/或其它溶液输注到静脉内患者给药线中的药物输注歧管。 歧管包括限定细长的在线流动通道的壳体,其在一端与载体流体入口管线连通,并且在另一端与患者进料管线连通。 在壳体中形成多个间隔开的药物入口,与流路连通。 每个入口开口设置有止回阀组件,该止回阀组件包括限定入口插口部分的阀构件和延伸到流动通道中的阀杆部分。 阀杆部分具有限定与插座部分连通的入口通道的圆柱形侧壁。 多个侧向入口端口延伸穿过侧壁。 弹性套筒构件以与入口端部相关的方式被容纳在阀杆部分周围。 阀杆部分与载流体通过流动通道的流动一致。
