More Information
Summary:A dual parenteral solution apparatus for delivering predetermined volumes of two solutions at predetermined flow rates with increased accuracy has a primary solution chamber (2) leading through a check valve (6), primary drip chamber (14) and flow control valve (20) to connective tubing (22) which leads to the patient. The supplementary solution container (24) leads through a supplementary solution drip chamber (26) and a valve (32) to a Y-junction (10) in the line from the primary solution chamber (2). The primary and secondary drip chambers (14, 26) have drop sensors (18, 28) respectively which operate to close valve (32) when the drop count in chamber (26) falls below that in chamber (14).
