  • Unitary withdrawal spike unit suitable for factory fitting
    Patent number: 9039673
    Abstract: A withdrawal spike unit (200) comprises a withdrawal spike component (30?) and an integrally formed adapter component (60?) that is adapted to couple with a vial (10) in a safe and secure manner. The integral formation of the component parts (30?, 60?) makes fully automated manufacture and assembly of assemblies comprising such a withdrawal spike unit (200) coupled to a vial (10) possible. As such, human errors associated with the assembly at the point of use are mitigated.

  • Component mixing apparatus and system including a movable cannula
    Patent number: 5743312
    Abstract: An apparatus for combining liquid or solid components stored in containers includes a cylindrical hollow body for receiving end closures of the containers and at least one cannula for penetrating the end closures. The cannula is mounted in a cannula holder movable in the hollow body, and retainer bridges connect the cannula holder to an inner wall surface of the hollow body. The retainer bridges fracture after the cannula penetrates the end closure in the first container so that the cannula moves toward the second container to penetrate the closure in the second container.Also disclosed is a system including the apparatus, two containers, and outer packaging enclosing the containers and the hollow body.
