Abstract
Abstract A disposible visualization wand for removal of bodily fluids from a graft, wound or other target site on a patient. The wand includes a barrel having a fan tip outlet, and a inlet end secured to a filter for removing contaminants from a gas stream feed for the wand. Also included is a liquid feed into the wand, for moisturizing the gas stream and preventing dehydration of the patient's tissue at the target site.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
131 words
A wand for delivering a fluid stream having at least a gas component to a target site on a patient, comprising: a first conduit defining a tubular barrel having an inlet end for receiving said gas component of said fluid stream from a gas source, and an outlet end; a flexible tip at said outlet end of said first conduit and defining a laterally elongated aperture for directing said fluid stream in a planar configuration to said target site; and a second conduit having an inlet end exterior to said first conduit for receiving a liquid component of said fluid stream, and an outlet end located beyond said first conduit outlet end and substantially within said tip for delivery of said liquid component into said gas component of said fluid stream.
Claim 2
Dependent Claim
131 words
A wand for delivering a fluid stream having at least a gas component to a target site on a patient, comprising: a first conduit defining a tubular barrel having an inlet end for receiving said gas component of said fluid stream from a gas source, and an outlet end; a flexible tip at said outlet end of said first conduit and defining a laterally elongated aperture for directing said fluid stream in a planar configuration to said target site; and a second conduit having an inlet end exterior to said first conduit for receiving a liquid component of said fluid stream, and an outlet end located beyond said first conduit outlet end and substantially within said tip for delivery of said liquid component into said gas component of said fluid stream.
Claim 3
Dependent Claim
40 words
The wand of claim 1, further including gas filter means in communication with said inlet end of said first conduit barrel for filtering microorganism contaminants from said gas component of said fluid stream prior to entry thereof into said barrel.
Claim 4
Dependent Claim
16 words
The wand of claim 1 further including valve means for selective occulsion of said second conduit.
Claim 5
Dependent Claim
12 words
