Abstract
Disclosed is a system to generate bubbles. The bubbles may be formed to include a substantially or medically pure gas. The bubbles may be formed on demand and in a selected small size.
Claims25
A method of forming a plurality of bubbles from a container, comprising:
- passing a gas saturated liquid through a tube from a source of the gas saturated liquid;
- wherein the tube includes at least one hydrophobic domain formed near a distal end on an internal surface of the tube;
- wherein the hydrophobic domain forms at least one bubble nucleation site.
A method of forming a plurality of bubbles from a container, comprising:
- flowing a gas saturated liquid through a bore of a tube having an augmented distal end;
- wherein the gas saturated liquid is passed from a source including a container having a liquid therein at a pressure of at least 100 psi and wherein the liquid is saturated to a partial pressure of at least 5 bar with a gas;
- and
- wherein the flow through the tube with the augmented distal end generates a population of bubbles having a mean size of less than about 15 microns.
1 more element
A method of forming a plurality of bubbles from a container, comprising:
- augmenting a distal end of a tube;
- and
- connecting the tube to a source of a gas saturated liquid;
- wherein a flow of the gas saturated liquid through a bore of the tube having the augmented distal end from the source is configured to generate a population of bubbles having a mean size of less than about 15 microns at least at the augmented distal end of the tube.
1 more element
An apparatus configured for forming a plurality of bubbles from a container, comprising:
- a tube having an elongated wall with an inner surface extending from a proximal end to a distal end, wherein the distal end of the inner surface is augmented;
- wherein the augmented distal end of the tube is configured to generate the plurality of bubbles when passing a gas saturated liquid through the tube from a source of the gas saturated liquid;
- wherein the augmented distal end forms at least one bubble nucleation site.
