Abstract
Abstract A fluid absorption mat is applied to the floor of a surgery room during medical procedures. Patient body fluids drip onto the mat while medical personnel stand on the mat. The fluids are absorbed by the mat through an upper and lower non-woven non-cellulose fibrous material and into a copolymer intermediate layer. The upper and lower layer dry while the intermediate layer retains any fluids absorbed by the mat. The mat is then disposed into a waste container. Medical personnel are thereby exposed to minimal patient body fluids and the clean up of the surgery room is more efficient and cleaner.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
165 words
A method of protecting surgery room personnel from exposure to patient body fluids or irrigation fluids comprising applying to a surgery room floor in an area into which patient body fluids can drip, and over which surgery room personnel must stand, a floor mat having at least three layers on which surgery room personnel stand, an upper layer and bottom layer of the floor mat made from a fluid absorbing non-woven, non-cellulose, fibrous material and an intermediate layer containing a fluid absorbent and retaining cross-linked polyacrylic acid/polyalcohol grafted copolymer mechanically interlocked between the two fibrous layers, an edge of the two fibrous layers joined together on all sides to hold together permanently the edges of the two fibrous layers to prevent outward migration of the copolymer and retaining the absorbed body fluids in the mat, drying upper and bottom layers of the floor mat, and disposing of the floor mat after a medical procedure without the outward migration of body fluids from the floor mat.
Claim 2
Independent Claim
165 words
A method of protecting surgery room personnel from exposure to patient body fluids or irrigation fluids comprising applying to a surgery room floor in an area into which patient body fluids can drip, and over which surgery room personnel must stand, a floor mat having at least three layers on which surgery room personnel stand, an upper layer and bottom layer of the floor mat made from a fluid absorbing non-woven, non-cellulose, fibrous material and an intermediate layer containing a fluid absorbent and retaining cross-linked polyacrylic acid/polyalcohol grafted copolymer mechanically interlocked between the two fibrous layers, an edge of the two fibrous layers joined together on all sides to hold together permanently the edges of the two fibrous layers to prevent outward migration of the copolymer and retaining the absorbed body fluids in the mat, drying upper and bottom layers of the floor mat, and disposing of the floor mat after a medical procedure without the outward migration of body fluids from the floor mat.
Claim 3
Dependent Claim
34 words
A method of protecting surgery room personnel from exposure to patient body fluids or irrigation fluids according to claim 1 wherein the copolymer is impregnated into a paper base to form the intermediate layer.
Claim 4
Dependent Claim
33 words
A method of protecting surgery room personnel from exposure to patient body fluids or irrigation fluids according to claim 1 wherein the edge of the two fibrous layers is enclosed by a binding.
Claim 5
Dependent Claim
34 words
A method of protecting operating room personnel from exposure to patient body fluids or irrigation fluids according to claim 1 wherein the edge of the two fibrous layers is joined together by a stitching.
