Abstract
A device for the uninterrupted administration of fluid to an animal body during a draw of bodily fluid, e.g., blood, is disclosed. A first fluid channel is configured to selectively transport IV fluid to an animal body and to draw a bodily fluid from the body. A sealing member for sealing a bodily fluid draw port defines a concave surface on a first end. The sealing member concave surface forms an interior surface portion of the first fluid channel. A connection member is configured to connect to a catheter to the first fluid channel and defines a concave distal end. A second fluid channel continuously provides IV fluid to a lumen coaxially located within the catheter. The concave surface and the concave distal end are shaped to create fluid flow patterns that quickly and completely remove residual bodily fluid remaining after a draw of bodily fluid is completed.
