Abstract
A selection valve, creating a minimal flow-through turbulence for use in the administration of three separately supplied intravenous fluids, for selecting with one-handed operation any one of the fluids connected or a mixture of any two fluids adjacently connected, is provided having a body with a cylindrically shaped cavity containing three closely positioned ports and a separately positioned port. A cylindrically shaped rotor may be disposed within the cavity and rotated to position a single passageway part thereof between the outlet and an inlet port. The outlet end of the passageway may be shaped to enable the exposure of the outlet port for any inlet port position. Preferably the valve body is mounted to a support structure which in turn may be secured to an immobile surface.
