Abstract

A fluid control device for directing fluid flow comprising a needleless access device for transferring fluids and methods of directing fluid flow. The fluid control device may have a first port, a second port, a third port and a connecting portion joining the first, second and third ports. A first valve element may be positioned within the first port and a fluid director may be positioned within the connecting portion. The first valve element may move between an opening position, where fluid may flow past the first valve element, and a closed position, where fluid may be prevented from flowing past the first valve element. The fluid director may have at least one passageway for connecting at least two of the first, second and third ports such that fluid may flow therebetween. An actuation mechanism may be used to orient the fluid director and, consequently, the at least one passageway within the connecting portion.
