Abstract
A fluid transfer device comprising two parallel fluid passages, both carried by a flange which is generally perpendicular to said passages, the improvement wherein the two ends of said passages on each of said flanges are longitudinally displaced from one another. The combination of a fluid transfer device comprising two parallel fluid passages, both carried by a flange which is generally perpendicular to said passages, the improvement wherein the two ends of said passages on each side of said flange are longitudinally displaced from one another; and a medicament container having an open end, an imperforate rubber stopper in said open end which seals said container, the one end of each of said fluid passages being adapted to pierce said stopper with said flange abutting the exterior of said stopper.
Claims3
A fluid transfer device comprising two parallel fluid passages within a single elongated rigid member having open cutting ends, said rigid member being carried by a generally disk-like flange disposed midway between the ends of said rigid member which is generally perpendicular to said passages, the improvement wherein said passages are of equal length and the two open ends of said passages on each side of said flanges are longitudinally displaced from one another, and further wherein said rigid member is provided with at least one lateral air hole in one of said passages and, on the opposite of said flange, the other of said passages is provided with at least one lateral hole to prevent the formation of fluid slug.
