Abstract
A wound irrigation device designed for use with a standard syringe and suction trap comprises a shield (10) which incorporates an irrigation tube (12) and nozzle (14) to deliver fluid at high pressure to a wound. The shield protects the operator from splashback, and includes a suction tube (16) to scavenge effluent, thus preventing spillage back into the wound or onto the patient and environs. A portable lavage/suction unit (28) may be used with the irrigation shield to provide fluid under pressure for irrigation, or to provide anesthetic under higher pressure for wound infiltration.
Claims18
A wound irrigation device, comprising:
- (a) a shield having a hollow shape, said shield having an interior surface, an exterior surface, a perimeter, and an interior volume,
- (b) a tubular irrigation nozzle protruding into said interior of said shield, said nozzle extending in a predetermined direction from said interior surface into said interior volume, wherein said nozzle further comprises means for varying said predetermined direction and the degree of protrusion of said nozzle into said interior volume;
- and
- (c) at least one suction aperture at said perimeter of said shield, whereby said wound will be irrigated without splattering or dripping dangerously contaminated fluids.
A wound-cleansing device, comprising:
- (a) a shield shaped to cover a predetermined area of a patient's integument and enclose said predetermined volume of space, wherein said shield further comprises an inner wall and an outer wall so as to provide a gap between said inner wall and said outer wall;
- (b) said shield having a perimeter where it contacts said integument;
- (c) a nozzle for conveying fluid to a wound on said predetermined area of said integument, said nozzle being attached to said shield and protruding into said predetermined volume, wherein said nozzle further comprises means for varying said predetermined direction and the degree of protrusion of said nozzle into said interior volume;
- (d) a suction aperture at said perimeter of said shield, and
- (e) effluent means connected to said suction aperture for conveying fluid, via said aperture, away from said predetermined volume, whereby a wound can be cleansed without the leakage of dangerously contaminated fluids and without the spread of contaminants from one part of a wound to another part of the wound.
