    • A stopcock is provided with multiple ports joining multiple fluid conduits leading between fluid sources and fluid destinations. A central hub manifold resides within a valve body supporting the ports, and can rotate relative to the valve body. Fluid flow paths within the central hub are selectively aligned or not aligned with the ports. The stopcock indicates which ports are open by providing marks corresponding with positions of the ports. When the marks are visible, the corresponding ports are open. With different positioning of ports and different configurations of fluid flow paths within the central hub, stopcocks having different numbers of operable positions are provided including two, three, four, six and eight way stopcocks. By providing an axial flow path through a central axis of the central hub intersecting the embedded fluid flow paths within the central hub, still further numbers of operational states are provided.
    • 旋塞具有多个端口,多个端口连接在流体源和流体目的地之间引导的多个流体导管。 中央轮毂歧管位于支撑端口的阀体内,并且可相对于阀体旋转。 中心集线器内的流体流动路径选择性地对准或不与端口对准。 旋塞阀通过提供与端口位置对应的标记来指示哪些端口打开。 当标记可见时,对应的端口打开。 通过不同的端口定位和中央集线器内的流体流动路径的不同构造,提供具有不同数量的可操作位置的活栓,包括两个,三个,四个,六个和八个方向的旋塞。 通过提供穿过与中心毂内的嵌入式流体流动路径相交的中心毂的中心轴线的轴向流动路径,还提供了更多数量的操作状态。

    • An assembly is provided which includes an infusion device coupled to a standard medication syringe. The medication syringe may be coupled to a stopcock valve having multiple ports and to which syringes, vial adapters, infusion tubing, and multiple other items may be coupled. The infusion device includes a source of power based on a resistance force such as vacuum, spring or gas power. The infusion device converts the resistance based force to usable work in the form of a force applicator. The force applicator includes a driver section on one section of a reciprocating arm and an attachment to the power source on another section of the arm. The driver is pulled outward (excursion) to increase the size of the chamber, creating a force that tends to return the driver back inward, causing incursion. The driver can be attached removably to the syringe plunger to induce the infusion process.
    • 提供了一种组件,其包括联接到标准药物注射器的输注装置。 药物注射器可以联接到具有多个端口的活塞阀,并且注射器,小瓶适配器,输注管和多个其它物品可以联接到该活门。 输液装置包括基于诸如真空,弹簧或气体动力的阻力的动力源。 输注装置以力施加器的形式将基于阻力的力转换成可用的工件。 施力器包括在往复臂的一个部分上的驱动器部分和在臂的另一部分上的电源的附件。 驾驶员向外拉(偏移)以增加舱室的大小,形成一种倾向于使驾驶员向内返回的力量,导致入侵。 驾驶员可以可拆卸地附接到注射器柱塞以诱导注射过程。
