Abstract
An apparatus for the uninterrupted administration of fluid to an animal body during clean blood collections is disclosed. Embodiments include an intravenous device defining a first fluid channel, wherein the first fluid channel is configured to selectively transport IV fluid to an animal body and draw a bodily fluid from the body, and a connection member configured to connect to a catheter to the first fluid channel and defining a concave distal end. A second fluid channel continuously provides IV fluid to a lumen coaxially located within the catheter. The concave surface is shaped to create a fluid flow pattern that quickly and completely removes residual bodily fluid remaining at the concave distal end. Embodiments include a concave surface defining an asymmetric funnel shape, a vertex of which is centered on the first fluid channel.
