Abstract
A medical valve transitions between an open mode that permits fluid flow, and a closed mode that prevents fluid flow. To that end, the valve has a housing with an inlet and an outlet, and a movable member with a member channel therethrough. The movable member is movable to cause the valve to transition from the closed mode to the open mode after insertion of a medical implement into the inlet. The member channel fluidly communicates the inlet and the outlet when in the open mode. The valve also has a resilient member with a member flow path in fluid communication with the outlet. The movable member slides along the resilient member when transitioning between the open mode and the closed mode. The resilient member normally has a flange (about the member flow path) that is compressed by the movable member. The flange fluidly disconnects the member flow path from the member channel when in the closed mode.
