Abstract

An IV manifold includes a plurality of injection/aspiration ports and has an elongate configuration with a width greater than the diameter of the ports. A flow channel is formed between mating members of a housing and provided with a U-shaped configuration. Projections along the flow channel direct fluid flow into valve cavities associated with the ports to clear dead spots around the valve elements. A check valve included in the manifold tends to direct high pressures against the valve elements which respond by forming surface seals thereby avoiding deformation. An aspiration port can be formed with a second seal disposed on the side of the valve element opposite the first seal. Opening this second seal by negative pressure in the lumen of the port provides for the aspiration of fluids in the flow channel. Two-way aspiration can be provided by a valve having a cage with or without compressible characteristics to accommodate low tolerance fittings.
