    摘要： 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.

    摘要： 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.
