Abstract
Abstract A surgical collection unit includes an inlet conduit, an outlet conduit, and an enclosed container. The inlet and outlet conduits have portions extending within and opening into the container. Means are associated with the outlet conduit for withdrawing air from the container to reduce the atmospheric pressure therein so that fluent material is forced through the inlet conduit into the container. A bypass conduit may be provided between the inlet conduit and the outlet conduit. A valve may be provided for directing the fluent material alternatively either through the bypass valve or into the container.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
135 words
A surgical trap comprising container means having flexible side walls, the outer portions of which are exposed to ambient air, said container means further including container inlet duct means and container outlet duct means each having at least one duct opening in communication with the interior of said container means, said inlet duct means adapted to be placed in communication with a source of substantially fluent material, said container means adapted to be placed in communication with suction means for drawing said fluent material into said container means, said trap further including a resilient protective member disposed in said container means across said inlet duct means to shield said inlet duct opening from blockage by the flexible side walls of said container means, such that said side walls remain spaced from said inlet duct opening.
Claim 2
Dependent Claim
135 words
A surgical trap comprising container means having flexible side walls, the outer portions of which are exposed to ambient air, said container means further including container inlet duct means and container outlet duct means each having at least one duct opening in communication with the interior of said container means, said inlet duct means adapted to be placed in communication with a source of substantially fluent material, said container means adapted to be placed in communication with suction means for drawing said fluent material into said container means, said trap further including a resilient protective member disposed in said container means across said inlet duct means to shield said inlet duct opening from blockage by the flexible side walls of said container means, such that said side walls remain spaced from said inlet duct opening.
Claim 3
Dependent Claim
42 words
A surgical trap as claimed in claim 1 wherein said resilient protective member is porous and extends dependingly across said inlet duct opening, such that fluent material passes from said inlet duct opening through said resilient porous member of said container means.
Claim 4
Dependent Claim
48 words
A surgical trap as claimed in claim 1 wherein said resilient protective member extends across said outlet duct opening to shield said outlet duct opening from blockage by the flexible side walls of said container means, such that said side walls remain spaced from said outlet duct opening.
Claim 5
Dependent Claim
19 words
A surgical trap as claimed in claim 1 wherein said resilient protective member is formed of a screen-like material.
Claim 6
Dependent Claim
37 words
A surgical trap as claimed in claim 4 wherein said protective member is also disposed across said outlet duct opening, said screen-like material being of a mesh that permits passage of said fluent material through said screen.
Claim 7
Dependent Claim
58 words
A surgical trap as claimed in claim 1 wherein said container means are collapsible into a flattened condition, entry of said fluent material into said container through said inlet duct opening causing said container to expand from said collapsed flattened condition, said expansion corresponding to the volume of said fluent material entering the interior of said container means.
Claim 8
Dependent Claim
52 words
The surgicAl trap of claim 1 wherein said container means is suspended from said inlet and outlet duct means, said trap further including a box having upper edges, said inlet and outlet duct means resting on said upper edges such that said container means hangs from said duct means within said box.
Claim 9
Dependent Claim
26 words
The surgical trap of claim 7 wherein said box includes vertical slots therein for permitting observation of the level of fluent material within said container means.
Claim 10
Dependent Claim
23 words
The surgical trap of claim 8 wherein said slots include indicia means for indicating the volume of fluent material within said container means.
Claim 11
Dependent Claim
11 words
The surgical trap of claim 7 wherein said box is collapsible.
Claim 12
Dependent Claim
20 words
The surgical trap of claim 9 wherein said box is open, said upper edges defining the border of said opening.
Claim 13
Dependent Claim
92 words
The surgical trap of claim 1 wherein said outlet duct means opens into the upper end of said container means, and said protective member extends across said outlet duct means, said container means and said outlet duct means being rotatable to an inverted position wherein a substantial portion of said container means is placed over said outlet conduit, said protective member shielding said outlet duct opening from blockage by the flexible side walls of said container means, thereby permitting fluent material in said container means to exit through said outlet duct means.
Claim 14
Dependent Claim
47 words
The surgical trap of claim 1 wherein bypass duct means extend between said inlet and outlet duct means providing communication therebetween, said trap further including valve means between said inlet and bypass duct means for making and breaking the communication between said inlet and outlet duct means.
Claim 15
Dependent Claim
38 words
The surgical trap of claim 1 wherein said inlet and outlet duct means are joined by bypass duct means, and valve means are provided between said bypass and inlet duct means for opening and closing the communication therebetween.
Claim 16
Dependent Claim
117 words
A surgical trap comprising an inlet conduit and an outlet conduit; an enclosed container; said inlet and outlet conduits having portions extending within and opening into said container; and means associated with said outlet conduit for withdrawing air from said container to reduce the pressure within said container; said inlet conduit being adapted to be placed in communication with a source of substantially fluent material; whereupon the reduction of pressure within said container causes the atmospheric pressure outside said container to force said fluent material through said inlet conduit into said container wherein said container is a collapsible bag suspended within a receptacle, said receptacle having at least one opening extending from its interior to the atmosphere.
Claim 17
Dependent Claim
117 words
A surgical trap comprising an inlet conduit and an outlet conduit; an enclosed container; said inlet and outlet conduits having portions extending within and opening into said container; and means associated with said outlet conduit for withdrawing air from said container to reduce the pressure within said container; said inlet conduit being adapted to be placed in communication with a source of substantially fluent material; whereupon the reduction of pressure within said container causes the atmospheric pressure outside said container to force said fluent material through said inlet conduit into said container wherein said container is a collapsible bag suspended within a receptacle, said receptacle having at least one opening extending from its interior to the atmosphere.
