ABSTRACT:
An intravascular catheter device that serves to control the loss of blood and subsequent contamination of the operator during placement, is disclosed. The catheter device comprises a cannula, a hub, and a generally cylindrical, resilient valve disposed within the hub. The valve includes an inner surface and an outer surface. The inner surface defines a passage in fluid communication with the cannula and has a plurality of longitudinal inner surface ribs. The outer surface has a plurality of outer surface ribs which are radially aligned with a respective one of the inner surface ribs. The catheter device further includes a ring for selectively compressing the outer surface ribs a distance to bring the inner surface ribs into mutual contact.
