Abstract: A device for the uninterrupted administration of fluid to an animal body during a draw of bodily fluid, e.g., blood from a blood vessel, 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 blood vessel via a catheter. A sealing member for sealing a blood draw port defines a concave surface on a first end. An outlet connector is configured to connect to a catheter to the first fluid channel and defines a concave distal end. An IV fluid inlet fluidly connected to an IV infusion lumen and configured for fluidic connection to an IV fluid source and uninterrupted delivery of IV fluid to the blood vessel. A valve member selectively provides a fluidic connection between the outlet connector and the IV fluid inlet, thereby selectively alternating between blood collection and IV fluid delivery.

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.

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.

Abstract: An infusion and blood collection device allows clean blood collections into a collection tube via a previously installed angiocatheter without interrupting the administration of intravenous therapies after initial installation. The device optionally includes passive control of the blood collection flow rate to prevent contamination of the collected blood draw with the IV therapy fluid being simultaneously infused through the angiocatheter. A blood collection method uses an infusion and blood collection device to draw a clean blood sample from a patient and into a collection tube via a previously installed angiocatheter without interrupting the administration of intravenous therapies.

Abstract: A micro-injection molded disposable needle assembly having more than one passageway formed therein to permit the simultaneous drawing and administering of fluids through separate passageways is disclosed. The micro-injection molded disposable assembly includes one or more sensors disposed therein for measuring and monitoring one or more desired body or surrounding environmental conditions. A method of forming the disposable needle from an elastomeric material using micro-injection molding is also disclosed.
