Abstract

A medical connector (10) disclosed comprises a first connector member (10) having an elongated hollow introducer needle (14). The introducer needle (14) has first and second end portions (16,18) and first and second spaced openings (20,22) to the hollow of needle (14) between the end portions (16,18). A second connector member (28) is connectable with the first connector member (12). The second connector member (28) includes a flashback chamber (30) having a rubber septum (32) and also a catheter tip (34) mounted thereon. The introducer needle (14) is axially movable through the rubber septum (32), flashback chamber (30), and catheter tip (34) to establish an opening in a patient's vein for placement of the catheter (34). The movement of the introducer needle (14) positions the first and second openings (20,22) within the flashback chamber (3) when the opening in the patient's vein is established whereby to provide venting of the needle (14 ) and flashback chamber (30) as the patient's blood is communicated through the first end portion (16) and into the flash-back chamber (30) providing visual confirmation of a successful stick by the presence of blood within the flashback chamber (30) while the air is displaced from the flashback chamber (30) through the second portion (18) and the hydrophobic vent filter in hub (36). A vent filter in hub (36) prevents blood spillage into the first connector member (10).
