Abstract: A fluid path for use in a fluid delivery system is described. The fluid path may have a connecter member having a lumen, a luer member connected to the lumen, and an annular member around the luer member. The fluid path may further have a check valve in the lumen to limit fluid flow in one direction. The check valve may have a deformable stopper element and a retaining sleeve disposed in the lumen of the connecter member. The retaining sleeve may have a central bore and a distal end against which the stopper element sits to prevent fluid flow through the lumen until a sufficient fluid pressure is present to deform the stopper element and unseat the stopper from the retaining sleeve. One or more grooves may be present in the receiving cavity. The fluid path may further have a drip chamber, a second tubing section, and a spike.

Abstract: The fluid path set is intended for use in a fluid delivery system. The fluid path set includes a multi-patient use section adapted for connection to a syringe used in the fluid delivery system, and to a source of fluid, such as contrast media, to be loaded into the syringe. The fluid path set further includes a per-patient use section that is removably connected to the multi-patient use section. A connector removably connects the multi-patient use section and the per-patient use section. A drip chamber is provided between the source of fluid and the syringe, and includes a projection for determining a level of fluid in the drip chamber. The per-patient use section includes a pressure isolation mechanism. The pressure isolation mechanism includes a lumen, a pressure isolation port, and a valve member with a biasing portion that biases the valve member to a normally open position.

Abstract: The fluid delivery system includes a fluid path set with a first section adapted for connection to a syringe and to a source of fluid to be loaded into the syringe, and a second section that is removably connected to the first section. A connector removably connects the first and second sections. The connector includes a first connector member having a first luer member and a first annular member disposed about the first luer member. The connector further includes a second connector member having a second luer member and a second annular member disposed about the second luer member. A check valve arrangement is disposed in of one of the first and second connector members for limiting fluid flow to one direction through the connector. The first and second annular members are adapted to operably engage to securely and releasably connect the first and second connector members.
