A valve is disclosed which includes a hollow cylindrical housing having a plurality of input sites and a rotary core member having an output pasageway. The input sites which are not in communication with the output passageway are sealed. The valve may also include a primary input site connected to a conduit surrounding the rotary core member of the valve. The valve is demountable on a control apparatus for performing a method of administering a plurality of fluids intravenously to a patient. According to the method of the present invention, a neutral solution is provided in between each of the other different fluid solutions being infused into the patient. The control apparatus of the present invention may be programmed to automatically provide the patient with a prescribed amount of each fluid solution through the catheter tube.

A valve demountable on a control apparatus for automatically providing selective communication between one of a plurality of available fluid sources and a catheter tube, the valve comprising: a hollow cylindrical housing having a plurality of input sites for connection with said fluid sources; a core member, rotatably engaged within said housing, having a planar surface on each end and an output passageway extending through said core member from an access hole in a circumference of said core member to an output hole in one of said planar surfaces connected to said catheter tube, said circumference of said core member sealing said input sites such that fluid is prevented from escaping from said input sites except when said access hole is aligned with one of said input sites to provide communication between said input site and said output passageway; conduit means for directing fluid from one of said input sites around said remaining input sites so that said fluid from said one of said input sites is in communication with said access hole whenever said access hole is positioned between two adjacent input sites; and gear means coupled to said core member for transmitting rotational movement from said control apparatus to said core member.
