Abstract

Abstract A device connectable to a suction source for drawing off particulate matter from the air about a burning site comprises a flexible hose provided along an end segment with a plurality of spaced apertures, a fastener for detachably connecting the hose at an end opposite the apertured end segment to the suction source, and a coupling element for securing a free tip of the hose, at the free end of the apertured end segment, to the hose along a middle portion thereof to thereby form a loop including at least a portion of the apertured end segment.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 167 words
A method for use in surgery to reduce air borne particles carrying infectitious micro-organisms, comprising the steps of: providing a substantially flexible hose with at least one linear end segment and a plurality of apertures spaced along said end segment; detachably connecting said hose at an end opposite said segment to a suction source; forming at least a portion said hose into a substantially loop-shaped configuration; disposing said portion of said hose on a skin surface of a patient so that said loop-shaped configuration at least partially surrounds a surgical site on the patient; exerting a force on said portion of said hose to maintain said portion of said hose in said loop-shaped configuration during a surgical procedure; surgically removing organic tissues from said surgical site; generating air-borne particulate matter as a by-product of said step of removing; and during said step of removing, operating said suction source to apply suction to said hose and thereby draw off particulate matter from the air about said surgical site.
Claim 2
Independent Claim 167 words
A method for use in surgery to reduce air borne particles carrying infectitious micro-organisms, comprising the steps of: providing a substantially flexible hose with at least one linear end segment and a plurality of apertures spaced along said end segment; detachably connecting said hose at an end opposite said segment to a suction source; forming at least a portion said hose into a substantially loop-shaped configuration; disposing said portion of said hose on a skin surface of a patient so that said loop-shaped configuration at least partially surrounds a surgical site on the patient; exerting a force on said portion of said hose to maintain said portion of said hose in said loop-shaped configuration during a surgical procedure; surgically removing organic tissues from said surgical site; generating air-borne particulate matter as a by-product of said step of removing; and during said step of removing, operating said suction source to apply suction to said hose and thereby draw off particulate matter from the air about said surgical site.
Claim 3
Dependent Claim 23 words
The method defined in claim 1, further comprising the step of releasably attaching said portion of said end segment to said skin surface.
Claim 4
Dependent Claim 36 words
The method defined in claim 2 wherein said step of releasably attaching includes the step of applying an adhesive strip to said skin surface, said adhesive strip being attached to said portion of said end segment.
Claim 5
Dependent Claim 26 words
The method defined in claim 3 wherein said portion of said hose is maintained in said loop-shaped configuration at least in part via said adhesive strip.
Claim 6
Dependent Claim 57 words
The method defined in claim 1 wherein said portion of said hose is provided with bendable means attached to said hose for maintaining said hose in an at least partially arcuate configuration formed by manipulation of said hose, said portion of said hose being maintained in said loop-shaped configuration at least in part via said bendable means.
Claim 7
Dependent Claim 15 words
The method defined in claim 5 wherein said bendable means is an elongate metal member.
Claim 8
Dependent Claim 15 words
The method defined in claim 6 wherein said metal member is disposed inside said hose.
Claim 9
Dependent Claim 46 words
The method defined in claim 1, further comprising the step of fastening a free end of said end segment to a middle portion of said hose, said end segment being maintained in said loop-shaped configuration at least in part by virtue of said step of fastening.
Claim 10
Dependent Claim 30 words
The method defined in claim 8 wherein said step of fastening includes the step of clipping said free end of said end segment to said middle portion of said hose.
Claim 11
Dependent Claim 30 words
The method defined in claim 8 wherein said step of fastening includes the step of tying said free end of said end segment to said middle portion of said hose.
Claim 12
Dependent Claim 39 words
The method defined in claim 1, further comprising the steps of providing said hose with a spacer element and attaching said spacer element to said skin surface to control the distance of said loop-shaped configuration from said surgical site.
Claim 13
Dependent Claim 50 words
The method defined in claim 1 wherein said hose is bifurcated along said end segment into two hose sections each provided with a plurality of spaced apertures, said step of forming including the step of bending at least a portion of one of said hose sections into an arcuate shape.
