Abstract
The invention concerns catheterization assemblies designed to reduce the risk of infection, transmission of bloodborne pathogens, loss of blood, and development of embolisms in a patient. Embodiments of the invention are directed to a catheterization assembly having a catheter hub with multiple access ports. In some embodiments, the catheter hub is permanently attached to a catheter and a valve. The catheter hub provides fluid communication between the valve and the catheter. The catheter hub may also be provided with a sealing member that provides access to a fluid passageway of the catheter hub but which prevents leakage of fluids from the catheter hub. In other embodiments, the catheter hub includes a passageway and an air vent for allowing air to pass out of the catheterization assembly.
