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.
Claims34
A sample site adapted to connect to a blunt cannula comprising:
- a housing;
- a liquid path extending into the housing;
- an actuator member fixedly positioned within the housing and having a lumen therethrough in fluid communication with the liquid path;
- an apertured exterior wall on the housing through which the blunt cannula can enter the housing to make fluid connection to the lumen;
- seal means adjacent the exterior wall aperture and presenting an outer surface generally flush with an in adjacent contact with the housing exterior wall for normally sealing the aperture against fluid communication with the lumen, the seal means being movable into the actuator member under pressure of the blunt cannula passing into the aperture so as to open a channel in the seal means and expose the lumen therethrough to the blunt cannula, the seal means channel being resealed and the exterior wall and seal means outer surface being substantially unobstructed with the blunt cannula removed.
