Abstract
Abstract A surgical floor mat having a plurality of compressed sponge sections with a low profile in a dry condition and a expanded profile in a wet condition for absorbing fluids which fall onto the sponge sections over the course of a surgical procedure. Furthermore, the compressed sponge sections are adhered to a waterproof and foldable sheet with a gap between each of the sponge sections to allow the foldable sheet and sponge sections to be easily folded for purposes of storage or later disposal. The waterproof and foldable sheet has a non-slip undersurface for secure engagement between the operating room floor and the surgical floor mat. Additionally, an adhesive strip can be used and affixed to the undersurface of the foldable sheet for greater securement to the floor and a number of different configurations for the surgical floor mat can be used.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
199 words
A surgical floor mat comprising: (a) a plurality of compressed sponge sections each having a low profile and being generally compact allowing a chair or stool with rollers to easily roll over said sections, and wherein said compressed sponge sections are sized and arranged so as to easily fold onto one another in a dry condition, and having an expanded profile in a wet condition for absorbing fluids which fall onto said plurality of compressed sponge sections over the course of a surgical procedure; and (b) a waterproof and foldable sheet having a top surface dimensioned to hold said sponge sections, wherein said sponge sections are adhered to said foldable sheets in side-by-side relationships allowing said sponge sections to be folded on top of each other; and wherein said foldable sheet having a non-slip bottom surface, whereby said surgical floor mat can be kept in a folded condition prior to surgical use, unfolded and placed on a floor in a safe condition for surgery, so as to be easily rolled over or walked over, and later refolded and discarded with any of the surgical fluid absorbed over the course of the operation trapped within said folded surgical floor mat.
Claim 2
Dependent Claim
199 words
A surgical floor mat comprising: (a) a plurality of compressed sponge sections each having a low profile and being generally compact allowing a chair or stool with rollers to easily roll over said sections, and wherein said compressed sponge sections are sized and arranged so as to easily fold onto one another in a dry condition, and having an expanded profile in a wet condition for absorbing fluids which fall onto said plurality of compressed sponge sections over the course of a surgical procedure; and (b) a waterproof and foldable sheet having a top surface dimensioned to hold said sponge sections, wherein said sponge sections are adhered to said foldable sheets in side-by-side relationships allowing said sponge sections to be folded on top of each other; and wherein said foldable sheet having a non-slip bottom surface, whereby said surgical floor mat can be kept in a folded condition prior to surgical use, unfolded and placed on a floor in a safe condition for surgery, so as to be easily rolled over or walked over, and later refolded and discarded with any of the surgical fluid absorbed over the course of the operation trapped within said folded surgical floor mat.
Claim 3
Dependent Claim
38 words
A surgical floor mat as claimed in claim 1, wherein said plurality of compressed sponge sections having a composition of cellulose, cloth fiber, and salt and having a dry profile ranging between 1 and 2 millimeters in thickness.
Claim 4
Dependent Claim
40 words
A surgical floor mat as claimed in claim 2, wherein said plurality of compressed sponge sections are separate and apart from each other by a distance of between 2 and 4 millimeters, thereby allowing foldability of said surgical floor mat.
Claim 5
Dependent Claim
31 words
A surgical floor mat as claimed in claim 3, wherein said non-slip bottom surface of said foldable sheet having an adhesive strip which can be adhered to a floor during use.
Claim 6
Dependent Claim
39 words
A surgical floor mat as claimed in claim 4, wherein said non-slip bottom surface of said foldable sheet having stippling for engagement between the floor and said surgical mat to provide engagement therebetween and a high coefficient of friction.
Claim 7
Dependent Claim
33 words
A surgical floor mat as claimed in claim 5, further comprising additional drainage canals interrupting each of said plurality of compressed sections to allow transport of surgical fluid throughout said compressed sponge sections.
Claim 8
Dependent Claim
