Ported catheter adapter having combined port and blood control valve with venting

A blood control valve for use in a ported catheter adapter, the valve comprising:

• a flexible tube, comprising:
• a proximal opening;
• a distal membrane;
• an inner cavity extending between the proximal opening and the distal membrane;
• an outer surface having a diameter that is approximately equal to an inner diameter of the ported catheter adapter, whereby the valve is configured to be retained within the catheter adapter via a friction fit, the outer surface further having a length sufficient to form a seal between a lumen of the catheter adapter and a pathway of a side port of the ported catheter adapter, and wherein the distal membrane divides the lumen of the ported catheter adapter into a proximal chamber and distal chamber;
• and
• a recess formed in the outer surface of the flexible tube, wherein the recess comprises a first end proximate the distal chamber when the valve is inserted into the catheter adapter and a second end disposed towards a middle portion of the flexible tube, wherein the recess has a cross-sectional area that permits the passage of air and prevents the passage of blood.
