1. An apparatus for supplying a fluid to a patient comprising:
- (a) a main supply means including a longitudinal fluid conduit having a distal end and a proximal end,a first fluid inlet means at said proximal end adapted for fluid communication with a fluid source,a first fluid outlet means at said distal end adapted for fluid communication with a syringe means and adapted to form a substantially fluid tight seal with a protective cap, anda first fluid control means between said first fluid inlet means and said first fluid outlet means for regulating fluid flow between said first fluid inlet means and said first fluid outlet means; and
(b) a fluid administration means including a longitudinal fluid conduit having a distal end and a proximal end,a second fluid inlet means at said proximal end of said fluid administration means adapted for fluid communication with the syringe means,a second fluid outlet means at said distal end of said fluid administration means adapted for fluid communication with a means for the delivery of fluid to a patient,a second fluid control means between said second fluid inlet means and said second fluid outlet means for regulating the flow of fluid between said second fluid inlet means and said second fluid outlet means and for regulating the flow of air in to and out of said fluid administration means, andan air filtering means in fluid communication with said second fluid control means; and
(c) a syringe means adapted for fluid communication with said first fluid outlet means and said second fluid inlet means.

Abstract
A fluid delivery apparatus for administering contrast media or other fluids to a patient. The apparatus includes a reusable main supply system, a disposable fluid administration system, and a transfer syringe. The transfer syringe is used to transfer fluid from the main supply system to the fluid administration system. The administration system includes an air valve and filter to allow for complete drainage of the fluid in the fluid administration system while reducing the likelihood of contaminating the fluid.
