Abstract: A roller clamp assembly for adjusting the fluid flow rate in a flexible infusion tube is provided. The roller clamp assembly includes a housing to receive the flexible tube, a plate slideably engaged with the housing and configured to rapidly compress the flexible tube to provide a coarse fluid flow adjustment, and a roller wheel moveable engaged with the housing and configured to provide a gradual fluid flow adjustment. The plate may be a slide plate received by grooves in an exterior wall of the housing, where the plate moves orthogonally to the flexible tube, or the plate may be a shim plate that moves along an interior wall of the housing in parallel to the flexible tube. Infusion sets and methods of adjusting fluid flow rates are also provided.

Abstract: A check valve, including a valve and a valve support surface, to permit a fluid to move through the check valve in a first direction and resist a fluid flow through the valve in a second direction, the valve having a valve diaphragm and an isolating bridge, with a portion of the valve engaging against valve support surface to resist deformation or stretching of the valve when a backflow of fluid into the check valve occurs. The valve support surface having a first surface portion and a second surface portion, and the valve positioned with the valve diaphragm spaced apart from the first surface portion, and the isolating bridge spaced apart from the second surface portion.

Abstract: Fluid connector systems including first and second valve assemblies couplable together to form a fluid pathway therethrough, and can resist fluid flow through the connector system when the valve assemblies are separated from each other, the first valve assembly including a compressible valve within a cavity and configured to surround a post forming a fluid passage, the compressible valve can resist fluid flow through the post in a first position and to reduce the resistance to fluid flow through the post in a second position, and the second valve assembly including a valve plug positioned within a bore and configured to obstruct a fluid passage, such that when the valve assemblies are coupled together the compressible valve is moved toward the second position and the post extends through the compressible valve and the valve plug to form the fluid pathway through the connector system.

Abstract: A device for coupling to a fluid connector of an IV administration set to resist contamination of the fluid connector and IV administration set and permit priming of the IV administration set. The device including a cover body having a cavity for receiving the fluid connector, a priming passage for priming fluid from the IV administration set through the fluid connector, and a coupling tab extending from the cover body, the coupling tab permitting the cover body to be coupled to a length of an IV line or other portion of the IV administration set to resist contamination and permit priming of the IV administration set.
