Abstract
Abstract A sample site having a needleless connector access port including a flush mounted valve assembly which is readily accessible for wiping clean with a disinfectant. A male Luer connector may be operatively connected into the access port by a split Luer arrangement of female Luer connector portions adjacent the access port aperture. The split Luer arrangement does not generally obstruct wiping access to the access port and may include moveable connector portions to provide completely unobstructed wiping access thereto.
