Abstract: A dual lumen coaxial cannula, assembly includes a first infusion tube having a first elongate body defining a first lumen therethrough and a second drainage tube co-axially aligned with the first infusion tube and having a second elongate body with a second lumen defined by a space between the first infusion tube and second drainage tube. A connector is removably attached to the first infusion tube and the second drainage tube for coupling the dual lumen coaxial cannula to an extracorporeal blood circuit. The first infusion tube and the second drainage tube include a plurality of infusion and drainage apertures, respectively, provided at the distal end and extending through the sidewall of the first infusion tube and the drainage tube, respectively.

Abstract: A bracket for supporting a flagstaff in several orientations and useful particularly in situations where it is required to quickly raise or lower the flag such as to signal presence of a water skier down in the water and dismounting when it is desired to store the flag when not in use, the bracket including a bar with a hole for insertion of the end of the flagstaff and rotatably mounted on a panel with notches around an edge each of which engages a spring loaded catch on the bar when it is rotated in a corresponding orientation. In one embodiment, the panel is a side panel of a channel and the joining leg of the panel slides into a slot in a bar bolted to a base such as the side of a boat.
