    • 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。

    • A parenteral solution container having a dual use access port used for both the administration of fluids to a patient as well as for the addition of fluids to the container, includes a generally cylindrical wall with an axial passage therethrough. A fluid-tight sealing means, having a reseal member that includes a slit therein to enable the reseal member to be pierced with a blunt, metal cannula, or sharp needle is removably attached to the dual use access port. When the dual use access port is used in its fluid addition capacity, the reseal member is attached to the wall and a blunt cannula is passed through the reseal member. Once the blunt cannula has been completely inserted, fluids may be added to the container. To use the dual use access port in its administration capacity, the sealing means is completely removed from the wall. A piercing pin is inserted into the wall creating a fluid-tight seal so that fluids may be administered to a patient.
    • 具有用于向患者施用流体以及将流体添加到容器中的双重用途进入口的肠胃外溶液容器包括具有穿过其中的轴向通道的大致圆柱形的壁。 一种流体密封的密封装置,其具有包括其中的狭缝的重新密封装置,以使得能够用钝的金属套管或尖锐的针刺穿重新密封构件,以可拆卸地连接到双重用途的进入口。 当双重使用进入口以其流体添加能力使用时,重新密封构件附接到壁上,并且钝头套管穿过重新密封构件。 一旦钝头插管完全插入,流体可以被添加到容器中。 为了在其管理能力中使用双重使用的接入端口,密封装置被完全从墙壁上移除。 刺穿的针被插入到壁中,产生流体密封,使得可以向患者施用流体。
