ABSTRACT:
A breathing circuit connector for intercoupling between the flexible hoses of an anesthesiology machine and the input connector of an endotracheal tube is disclosed. The breathing circuit connector consists of a hollow body of relatively rigid material having a cylindrical male input section and a cylindrical female output section. A cylindrical bore within the hollow body extends between the cylindrical input and output sections. The bore within the cylindrical output section consists of a series of two or more cylindrical portions having different internal diameters. The internal diameter of the first bore portion adjacent the output end of the cylindrical output section is slightly larger than the internal diameter of the bore portion situated within the cylindrical output section. The breathing circuit connector may be formed as an elbow with the longitudinal axis of the bore of the cylindrical output section being inclined relative to the longitudinal axis of the bore of the cylindrical input section. Alternatively, the improved connector may comprise a single female output section and a pair of cylindrical male sections, each section having a bore whose axis is displaced from the other to form a Y-shaped connector.
