Abstract: A contrast media delivery system having a flow regulator assembly that allows a practitioner to regulate the passage of contrast media into a burette while minimizing turbulence and the formation of microbubbles in the contrast media. The flow regulator assembly can be actuated by twisting a rotatable cap. When the rotatable cap is released, the flow of contrast media from the inlet to the burette is stopped. A diffuser having a contact surface is provided which disperses contrast media as it passes into the burette to ensure that the contrast media flows smoothly and uniformly down the wall of the burette and into the volume of contrast media. A float and seating assembly which provides optimal sealing of the outlet of the burette while also allowing separation of the float from the seat when the burette is being refilled with contrast media.

Abstract: The present invention is directed to a vascular blood containment that allows a user to determine whether a blood vessel has been accessed and which provides access to the vessel. The vascular blood containment device includes a compression seal having increased reliability. The seal permits the passage of gas but prevents the passage of liquid. A valve providing access to a blood vessel through the blood containment device is configured to conform to an inner profile formed around a bore of the distal end of the outer housing. The configuration of the device permits the blood containment chamber to fill properly when the distal end of the blood containment device is positioned below the proximal end of the device.
