    Abstract: A spike assembly having an elongate spike defining a hollow cannula that is in fluid communication with the interior of a liter connection portion. The spike assembly provides needleless access to a stopper of a vial to facilitate injection and withdrawal of fluids via a syringe barrel selectively secured to the luer connection portion. The syringe can safely be removed from the spike assembly and then be directly attached to a luer compatible connector. The elongate spike may include a frangible tip portion that can break away from the spike assembly within a vial. The spike assembly may have a neck with a pair of gripping wing members. The spike assembly may have a feature that prevents rotation of the spike in the vial stopper, thereby allowing the syringe to be easily and safely disconnected from the spike assembly without having to grasp the spike assembly.

    Abstract: An infusion pump (110) includes a housing (112); a rotor (230) inserted into the housing, the rotor including a first ring (38a) of surfaces (236a) that form channels with the housing, and a second ring (38b) of surfaces (236b) that form channels with the housing, the second channel forming surfaces radially offset from the first channel forming surfaces; and a motor (40) operably engaged to rotate the rotor to cause the first and second channel forming surfaces to pump a flow of fluid, the radial offsetting of the second channel forming surfaces from the first channel forming surfaces dampening a pulsatility of the flow of fluid.
