Patent ID: 8002755

Claim:
A medical valve having an open mode that permits fluid flow, and a closed mode that prevents fluid flow, the medical valve comprising: a housing having an inlet and an outlet; and a valving mechanism within the housing to alternatively fluidly connect the inlet and the outlet, the valve being in the open mode when the inlet and outlet fluidly connect, the valving mechanism including a rotating member with a member channel therethrough, and a resilient member supporting the rotating member; insertion of a medical implement into the inlet producing a positive fluid displacement at the outlet, the rotating member being rotatable to cause the valve to transition from the closed mode to the open mode after insertion of the medical implement into the inlet, the member channel fluidly communicating the inlet and outlet when in the open mode, withdrawal of the medical implement as the valve transitions from the open mode to the closed mode producing a substantially neutral fluid displacement at the outlet, wherein the rotating member rotates at an angular rate that is a function of the longitudinal insertion rate of the medical implement, the rotating member rotating at a variable rotational rate when the medical implement moves longitudinally at a substantially constant rate.
