Abstract
A suction catheter and method of using same in which oxygenated irrigating fluid is provided to the suctioning site. The oxygenated fluid can be formed using a Y-connector to mix oxygen and fluid in a single conduit, a reservoir of fluid having oxygen bubbled into it, or through the use of an oxygen exchanger. Pressurized oxygen-containing gas may be fed to the Y-connector to force the gas and irrigating fluid out through the catheter. The suction may be a dual lumen catheter or a tube within a tube.
Claims8
A suction catheter suitable for use in removing undesirable fluid from a patient, said suction catheter comprising:
- a tube having a proximal end and a distal end, said distal end being suitable for insertion into a patient wherein said tube includes a primary conduit for removing fluid from a patient upon application of a vacuum and a secondary conduit for providing liquid for lavaging said patient;
- a cross piece mounted so as to surround said tube in the vicinity of the distal end of said tube;
- a suction control means attached to said tube in the vicinity of the proximal end of said tube;
- a vacuum connector at the proximal end of said suction control means;
- an input tube, connected to said secondary conduit, for providing oxygenated liquid to said secondary conduit;
- and
- a reservoir of irrigating fluid connected to said input tube, said reservoir having oxygen bubbled in through said irrigating fluid.

- and
- a source of irrigating fluid connected to the other of said two input ends of said Y-connector.
A method for removing undesired debris from a cavity in a patient comprising the steps of:
- inserting a suction catheter into said cavity;
- dissolving oxygen in an irrigating fluid solution to produce oxygenated irrigating fluid by bubbling oxygen in a reservoir of irrigating fluid;
- delivering the oxygenated irrigating fluid through a first conduit in said catheter to said cavity so as to dislodge debris;
- and
- administering a vacuum through a second conduit in said catheter so as to remove dislodged debris and irrigating fluid from said cavity.
A method for removing undesired debris from a cavity in a patient comprising the steps of:
- introducing a catheter into said cavity;
- feeding an irrigating fluid into one arm of a Y-connector which feeds said irrigating fluid through said catheter;
- feeding a gas under pressure into a second arm of said Y-connector to mix said gas with said fluid and to eject said mixture of fluid and gas under force from said catheter and into said cavity;
- and
- administering a vacuum in said catheter to remove dislodged debris and irrigating fluid.
