Abstract
A fluid transfer device for accessing fluid from vials and ampoules includes a cannula assembly. The cannula assembly includes a hub. The fluid transfer device further includes a filling straw with a proximal end, a distal end and a passageway therethrough and a housing with an outside surface fixedly attached to the proximal end of the straw. The housing has a cavity therein to receive at least a portion of the cannula assembly. The housing has at least one flexible arm attached to the housing at an inboard end, with the arm projecting and being biased outwardly from the housing. The arms each have an outboard end with a lug thereon. The fluid transfer device of the invention also has a removable shield. The invention indcludes a shield with a sidewall that has at least one elongate open slot from the open proximal end and an opening in alignment with and spaced distally to the slot. The shield is disposed so that the filling straw and at least a portion of the housing is within the shield. The shield has an unlatched positioned wherein the shield is removable from the housing to expose the filling straw for use, and a latched position wherein the shield and the housing are locked together to form a unitary structure. The shield and the housing are locked together by replacement of the shield onto said housing so that the arm is within the slot and the lug engages the hole.
