  • Patent number: 8663782
    Abstract: A floormat for handling fluids is formed, at least in part, of compressible and resilient material. The topside of the floormat has a spaced plurality of channels feeding one or more gutters. The topside also has a central region and a border region. The central region occupies most of the topside and is substantially flat throughout except for the channels. One or more gutters in the floormat communicate with the distal ends of the channels. One or more discrete outlet gutters in the floormat allow drainage off the floormat. After placing the floormat where a user is expected to stand during the procedure, fluids that fall onto the floormat will flow from the channels to the one or more gutters for removal from one or more discrete locations on the one or more gutters.

  • Patent number: 7785692
    Abstract: A floormat arranged to shed fluids has a topside and an underside. The floormat is placed where a user is expected to stand during a procedure. Fluids released during the procedure are allowed to fall onto and be shed off the floormat before being removed. The floormat may be discarded before starting another procedure. The mat is formed, at least in part, of compressible and resilient material. The topside of the mat has a spaced plurality of channels. In one instance, each of the channels has a floor sloping in opposite directions from a central peak. In another instance, the mat has a tapered apron bordering a central section that is convexly crowned to shed fluids. In other embodiments the topside of the central region is substantially flat except for the spaced plurality of channels. The floormat may be placed where an operator is expected to stand during the procedure. Fluids that fall onto the floor mat are shed therefrom and then removed. The floormat is discarded before starting another procedure.
