Abstract
A method for generating microbubbles may include providing a syringe having a barrel defining an interior volume, a plunger, a tip and a check valve assembly. The check valve assembly may have an inlet port; a check valve that is configured to open when the plunger is drawn back by a user; and a nozzle in fluid communication with the interior volume and, when the check valve is open, in fluid communication with the inlet port. The method may include drawing liquid into the interior volume; removing a seal from the inlet port and drawing gas adjacent the inlet ports into the interior volume to form microbubbles in the liquid already drawn in; coupling the tip to an intravenous line associated with a patient undergoing a bubble study; and depressing the plunger to force the liquid and the formed microbubbles into the intravenous line.
