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).

Medical connector

A medical connector (10) disclosed comprises a fist 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 flashback chamber (30) providing visual confirmation of a successful stick by the presence of blood within the flashback chamber (30) before all the air is displaced from the flashback chamber (30) to prevent the possibility of blood spillage to the second portion (18).

A medical connector (10) disclosed comprises first and second connector members (12, 22) including a flashback chamber (26), a needle (20) penetrable into said chamber and an improved one-way valve (32) spaced from said needle for closing said chamber and for establishing fluid communication through the connector (10) when the connector members (12, 22) are joined to administer medication or food to the patient while preventing a patient's blood from entering the chamber (22) and coming in contact with the needle.

An infant feeding device (10) disclosed includes a flexible elongated tube (12) including a longitudinal bore (14) therethrough for delivering liquid into the stomach of an infant. The tube (12) has an inlet (16) which is connected to a reservoir of the liquid, an intermediate portion (18), and an outlet (20) which includes a plurality of the laterally extending ports (22) so that the liquid may be delivered outwardly therethrough into the infant's stomach. A pliable plastic tip (24) including a cavity (30) having a fluid therein is affixed to the outlet (20) and protects delicate membranes and tissues of the infant as the feeding device is inserted into the nasogastric passages.
