Abstract
A fluid transfer device for accessing fluid from vials and ampoules includes a cannula assembly that defines an axis. The cannula assembly includes a cannula with a proximal end, a distal end and a lumen therethrough. The cannula assembly also has a hub fixedly attached to the proximal end of the cannula that has an open proximal end in fluid communication with the lumen. The fluid transfer device has a filling straw with a proximal end, a distal end and a passageway therethrough and a housing with an outside surface that is fixedly attached to the proximal end of the straw. The housing has a cavity therein to coaxially receive at least a portion of the cannula assembly to form a fluid path between the open proximal end of the hub and the distal end of the filling straw. The fluid transfer device also has a removable shield with an open proximal end, a distal end, an outside surface, and a sidewall that defines a receptacle therein. The shield is rotatable with respect to the housing from a first position wherein the shield is removable from the housing to expose the filling straw for use and a locked position wherein the shield and the housing are locked together to form a unitary…
