Rotary medical manifold

Abstract

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.

What is claimed is: 
     
         1 . An apparatus comprising:
 a manifold body including a central cavity, an output port, a first fluid port, and a second fluid port;   a valve stem, adapted to slidably engage the central cavity, the valve stem including:
 a single central longitudinal fluid passage connected to an injector port; 
 a first perpendicular fluid passage intersecting the central longitudinal fluid passage to selectively provide fluidic transport between the central longitudinal fluid passage and the output port when the valve stem is in a first rotational position; and 
 a second perpendicular fluid passage intersecting the central longitudinal fluid passage to selectively provide fluidic transport between the central longitudinal fluid passage and a selected one of the first and second fluid ports, fluidic transport to the first fluid port is provided when the valve stem is in a second rotational position and fluidic transport to the second fluid port is provided when the valve stem is in a third rotational position; and 
   wherein a proximal portion of the valve stem is adapted to enable selective rotation of the valve stem within the central cavity to rotatably selectively provide fluidic transport between the central longitudinal fluid passage and one of the first fluid port, the second fluid port, and the output port.
