Abstract

fluid control component (100) configured for controlling fluid flow through the hub of a catheter assembly during and after placement into the patient is disclosed. In one embodiment, the fluid control component comprises a body disposed within a cavity of the hub, the body being movable between a first position and a second position, wherein the body does not pierce a valve (102) disposed in the hub when in the first position and wherein the body pierces the valve when in the second position. The body includes a conduit (106) to enable fluid flow through an internal portion of the body when the body is in the second position, and a plurality of longitudinally extending ribs (110) disposed on an exterior surface of the body. The ribs provide at least one fluid flow channel between the valve (102) and an external portion of the body when the body is in the second position. Each rib includes a notch for maintaining the body in the first position prior to piercing the valve by engagement with a rib in the cavity and a protrusion that engages the rib to prevent further movement of the body after piercing the valve.
