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 structure removable from hub to expose the cannula. The outside surface of the housing and the outside surface of the shield include an indication of the shield's rotational position with respect to the housing.
