Abstract
Abstract A shield for eliminating smoke created during electrocautery surgery includes an elongated base member and an upwardly extending concave wall secured to one edge thereof. Located on the upper surface of the base member is an elongated suction tube which extends along the base member. A plurality of vertical openings in the upper surface of the tube create an air flow when the tube is connected to a vacuum source. Air and smoke in the vicinity of the shield are drawn inwardly toward the top of the shield, down the inner surface of the concave wall and into the suction tube. The bottom surface of the base member has a pressure sensitive adhesive thereon so that the shield can be mounted on a patient or on the patient's surgical gown or covering adjacent the surgical area.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
156 words
A shield for eliminating smoke generated during electrocautery surgery comprising: an elongated substantially flat and flexible base member, said base member having a pressure sensitive adhesive on the lower surface thereof; a flexible sheet-like material attached to one edge of said base member and extending substantially upwardly therefrom; rigid support means connected to the upper surface of said base member and extending between said base member and the upper portion of said sheet-like material for maintaining said material in a substantially concave configuration; an elongated suction tube mounted on the upper surface of said base member and extending throughout at least the central portion thereof, said tube having a plurality of vertically oriented openings therein, and means for connecting said tube to a vacuum source to thereby create a flow of air from in front of said shield inwardly toward the top of the shield and down the inner surface of said material to said tube.
Claim 2
Dependent Claim
156 words
A shield for eliminating smoke generated during electrocautery surgery comprising: an elongated substantially flat and flexible base member, said base member having a pressure sensitive adhesive on the lower surface thereof; a flexible sheet-like material attached to one edge of said base member and extending substantially upwardly therefrom; rigid support means connected to the upper surface of said base member and extending between said base member and the upper portion of said sheet-like material for maintaining said material in a substantially concave configuration; an elongated suction tube mounted on the upper surface of said base member and extending throughout at least the central portion thereof, said tube having a plurality of vertically oriented openings therein, and means for connecting said tube to a vacuum source to thereby create a flow of air from in front of said shield inwardly toward the top of the shield and down the inner surface of said material to said tube.
Claim 3
Dependent Claim
26 words
The invention as claimed in claim 1 further including means for connecting the upper corners of said sheet-like material to the ends of said base member.
Claim 4
Dependent Claim
36 words
The invention as claimed in claim 1 wherein said connecting means is centrally located with respect to said tube and wherein said openings increase in size from the center of said tube to the ends thereof.
Claim 5
Dependent Claim
35 words
The invention as claimed in claim 1 wherein said rigid support means are pivotally connected to said base member so that they can be pivoted between a lower inoperative position and an upper operative position.
Claim 6
Dependent Claim
37 words
The invention as claimed in claim 1 wherein said rigid support means are comprised of a pair of supports, each of said supports including a substantially vertically extending portion and a portion extending upwardly and rearwardly therefrom.
Claim 7
Dependent Claim
77 words
A shield for eliminating smoke generated during electrocautery surgery comprising: an elongated substantially flexible base member; adhesive means on the lower surface of said base member for securing the same to a patient; an upwardly extending concave wall connected to said base member; a rigid support means attached to said base member and extending between said base member and said concave wall; suction means associated with said wall for drawing air and smoke inwardly toward said wall.
Claim 8
Dependent Claim
77 words
A shield for eliminating smoke generated during electrocautery surgery comprising: an elongated substantially flexible base member; adhesive means on the lower surface of said base member for securing the same to a patient; an upwardly extending concave wall connected to said base member; a rigid support means attached to said base member and extending between said base member and said concave wall; suction means associated with said wall for drawing air and smoke inwardly toward said wall.
Claim 9
Dependent Claim
20 words
The invention as claimed in claim 6 wherein said suction means is located adjacent the lower portion of said wall.
Claim 10
Dependent Claim
24 words
The invention as claimed in claim 7 wherein said suction means is comprised of a tube having a plurality of vertically oriented openings therein.
Claim 11
Dependent Claim
17 words
The invention as claimed in claim 6 wherein said wall is comprised of a flexible sheet-like material.
