Abstract

Apparatus for parenteral fluid administration to a patient wherein a pliant bag containing the liquid to be administered is supported between two pressure pads having mutually-confronting, spaced-apart, pressure-applying faces. A side edge and the bottom edge of one of the pads is offset from the corresponding side and bottom edge of the other pad. As one pressure pad approaches the other, pressure is applied to the pliant bag and the liquid is forced therefrom through a bottom outlet disposed below the pressure plates. When the pliant bag is fully squeezed and its side-walls are in contact, portions of the pliant bag adjacent the offset bottom edges and the offset side edges of the pressure plates form a lateral duct at the bottom of the bag for the remaining liquid and a riser duct which is in communication with the lateral duct and extends for the full height of the bag interior. Any gases present in the pliant bag rise to the top of the riser duct while the liquid remains at the bottom of the bag in the lateral duct. Thus no gas is ever administered to the patient.
