Abstract: A catheter assembly includes a catheter hub and an introducer needle. The introducer needle extends through the catheter hub and through a catheter tube so as to assist placement of the catheter tube into a patient's blood vessel. Blood flashback into the catheter tube and/or catheter hub can indicate when the catheter tube is properly positioned within the blood vessel. After proper catheter tube placement is confirmed through blood flashback, the introducer needle is withdrawn. A septum blocks flashback blood from flowing proximally out of the catheter hub. One or more air vents enable air within the hub to vent when flashback blood enters the catheter hub. A porous hydrophobic material covers the one or more air vents. The hydrophobic material allows the air to flow therethrough and through the vents, but repels blood, blocking blood from flowing through the air vents.
