A fluid transfer device for accessing fluid from vials and ampoules includes a cannula assembly including a cannula having a lumen therethrough connected to a hub having an open proximal end. A filling straw includes a housing at its proximal end, a needle portion at its distal end and a shaft portion therebetween. The housing includes a cavity in its proximal end in fluid communication with a passageway running through the filling straw. A cutting edge is provided at the distal end of the needle portion for piercing a vial stopper. The cannula assembly is removably engaged with the housing so that the open proximal end of the hub is in fluid communication with the passageway of the filling straw. An elongate shield having an open proximal end and a recess therein is removably connected to the straw so that the shaft portion and the needle portion of the straw are contained within the recess.

[ What is claimed is:] [1.] A fluid transfer device for assessing fluid from vials and ampoules comprising:a cannula assembly including a cannula having a proximal end, a distal end and a lumen therethrough, and a hub having an open proximal end with a recess therein having a frusto-conically shaped surface for removable connection to a fluid transfer device having a frusto-conically shaped tip, and a distal end joined to said proximal end of said cannula so that said lumen is in fluid communication with said open proximal end of said hub;a filling straw having a proximal end, a distal end, and a passageway therethrough, said straw including a housing at said proximal end, a needle portion at said distal end and a shaft portion therebetween, said housing having a cavity in its proximal end in fluid communication with said passageway, a cutting edge at the distal end of said needle portion for piercing a vial stopper, and means for removably engaging said cannula assembly with said housing so that said open proximal end of said hub is in fluid communication with said passageway of said filling straw and said cannula assembly removably engaged with said housing; anda shield having an open proximal end, a distal end and a sidewall therebetween defining a recess in said shield, said shield being removably connected to said straw so that said shaft portion and said needle portion are contained within said recess.
