Abstract
A device and method for dispensing a liquid with a gas includes an instrument having a cannula and a low-pressure tip. The low-pressure tip includes a tip housing that at least partially defines a high pressure chamber. A distal wall of the tip housing includes an aperture in fluid communication with the high pressure chamber. The low-pressure tip also includes a tube and a gas flow channel. The tube fluidly communicates liquid at a relatively low pressure from the cannula through the first aperture. The gas flow channel fluidly communicates gas from the cannula at a relatively high pressure and to the high pressure chamber for discharge from the aperture. The tube and aperture are adapted to dispense the liquid and the gas in order to create a low pressure zone distal of the tube to dispense droplets of the liquid.
