A rotary medical manifold, for delivering various fluids through a patient delivery mechanism is described. The rotary manifold can include a manifold body and a valve stem. The manifold body can include a central cavity, an output port, a first fluid port, and a second fluid port. The valve stem can include an injector port, and a single central fluid passage. The valve stem can be adapted to slidably engage the central cavity of the manifold body and provide selective fluidic connectivity between the injector port and the output port, the first fluid port and the second fluid port.
