Abstract
A method of degassing utilizing a degassing faucet having a first portion which includes a liquid inlet with a first cross-sectional area and a liquid outlet with a second cross-sectional area smaller than the first cross-sectional area, the liquid outlet being disposed adjacent a conduit portion having a cross-sectional area larger than the second cross-sectional area and the degassing faucet having a second portion with an impact surface. The method includes the steps of (1) causing a liquid to flow from the liquid inlet to the liquid outlet with a velocity which increases as the liquid flows from the liquid inlet to the liquid outlet; (2) causing the liquid to pass from the liquid outlet to the conduit portion to create a pressure decrease in the liquid with respect to the atmosphere; (3) impacting the liquid against the impact surface while the pressure decrease is present in the liquid to cause the liquid to be degassed; and (4) accumulating the degassed liquid in a tub positioned underneath the degassing faucet and being sized to facilitate the ultrasonic treatment of a human patient.
