Mat Type Patents (Class 4/581)
  • Patent number: 11779425
    Abstract: A color-coded surgical table covering or floor mat and/or a surgical color-coded skin marker can be used in a medical setting to identify a bodily location of patient for which a medical procedure is to take place. The surgical color-coded skin marker may be used to mark the location of the medical procedure site on a patient. The medical patient would be oriented to match the surgical table covering or floor mat body form that identifies, through color and orientation, or text, the bodily location of a medical procedure to take place. The combination of the two (table covering/floor mat and skin marker) provides an unmistakable indication that will help limit or reduce wrong-site medical procedures. A surgical mat using a color-coded system or using visual indicia may be used to identify the medical procedure site to medical practitioners, in order to reduce wrong-site medical procedures.

  • Patent number: 6455123
    Abstract: In a preferred embodiment, the present invention comprises a layer having carpeted upper surface and/or other rubber-like padding material covered by a translucent, elastomeric sheet. The upper elastomeric layer may have downwardly depending projections that engage the carpeted upper surface of the inner padding layer, thereby reducing the likelihood of the upper elastomeric layer from slipping relative to the inner padding layer. The upper elastomeric layer is sewn or otherwise affixed to the carpeted surface to prevent slipping and creasing of the upper elastomeric layer relative to the padding during use. In addition, in a preferred embodiment for use on carpeted surfaces, the lower elastomeric layer may have downwardly depending projections that engage in the underlying carpet surface to reduce slipping of the device relative to the underlying surface. An overcovering material may be provided to further protect the upper elastomeric layer from excessive soiling.

  • Publication number: 20020061693
    Abstract: The present invention provides a liquid absorbent fibrous substrate having a plurality of discontinuous cells in which a second material is disposed. This second material is selected from a broad variety of organic or inorganic solids which may provide a reinforcing effect such that a sharp instrument is prevented from passing through the new composite structure. The reinforcing materials are disposed in a discontinuous array, in a cellular form in the fibrous substrate thus providing a path for liquids to be absorbed into said fibrous substrate, while said reinforcing materials provide resistance to penetration by sharp edged instruments. When disposed in this manner, flexibility is maintained since the reinforcing materials are not disposed in a continuous pattern. Preferably, the pattern disposed is free of linear regions that provide a continuous line of penetration for sharp edges.

  • Patent number: 6372323
    Abstract: A slip control article including a backing layer having a first surface with an array of at least 100 upstanding stems per square inch and a second surface. At least a portion of the upstanding stems is an elastomeric material and the stems have an aspect ratio of at least 1.25. The first surface has a static coefficient of friction when dry of at least 0.6 and a static coefficient of friction when wet within 20% of the static coefficient of friction when dry. The first surface has a peel strength and a tensile strength of substantially zero when engaged with another slip control article. The first surface has a relatively high shear strength when engaged with another slip control article. The high shear forces are due primarily to the frictional properties of the elastomeric materials, not a mechanical interlock of the stems, such as on a mechanical fastener.

  • Patent number: 5173346
    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.

  • Patent number: 5069951
    Abstract: A magnetized bath mat removably connectable atop the magnetically attractive bottom of a bathtub or shower stall including a thin, flexible magnetic base sheet permanently adhered to and beneath a thin, flexible non-magnetic upper sheet. The base sheet is permanently magnetized so that its bottom surface is releasably attractable to the tub or shower bottom to provide a high degree of slip resistance between the bath mat and the tub or shower bottom during normal use. The upper sheet is coextensive with the base sheet and has a top surface which is generally slip resistant to a user standing or sitting thereatop under wet conditions of use. A very thin intermediate sheet having an opaque coloring similar to that of the upper sheet and permanently adhered between the base and upper sheets may be provided to prevent visual color bleeding of the dark-colored base sheet through to the upper sheet.

  • Patent number: 4894875
    Abstract: A sink mat is set forth wherein the mat is of a generally rectangular configuration formed of laminated polymeric layers. The layers are mechanically or adhesively secured together to capture coil springs therein. THe coil springs are formed in a plurality of circular patterns originating from the center of the mat to cushion and absorb impact when positioned. Furthermore, a plurality of bendable elongate wires are captured within spaced peripheral positions within the laminated layers to enable deformation and recontouring of the mat to accommodate variations in associated sink contours.

  • Patent number: 4860510
    Abstract: A modular tile for interlocking with other similar tiles to form a surface covering which provides a cushioned surface suitable for use in an outdoor playground environment which allows water to substantially flow thereunder for purposes of draining free from the tile. The tile includes a flat support grid having a top and bottom surface and including a repeating pattern of inersection cross members which are integrally formed with interstitial openings therebetween. A plurality of support legs are attached at the bottom surface of the support gird to raise the grid above the supporting surface of concrete or other material. Means are provided around the perimeter of the support grid to allow attachment of additional grids in an interlocking manner.

  • Patent number: 4630323
    Abstract: An improved bathtub liner. The bathtub liner includes resilient pads encapsulated by a covering having a smooth continuous surface which detachably adheres to the inner surfaces of a bathtub and resists shear forces which tend to cause the continuous surface to slide over the inner surfaces of the bathtub. The bathtub liner includes a bottom pad shaped to cause water to flow under the force of gravity down the pad toward the bathtub drain when the tub is being emptied of water.

  • Patent number: 4625715
    Abstract: A whirlpool bath massaging apparatus having a bubble mat, a distributor having a control switch for regulating the air supply, and control means including a blower which is in communication with the bubble mat through an aerator tube and the distributor. The distributor is in the form of a self-contained structural unit separate from the bubble mat and is provided with inlet connecting means for the aerator tube and with outlet connecting means in the form of connector studs equal in number as there are partial sections of the bubble mat. The distributor with the control switch thereon forms an insertable unit which is installed in a receptacle provided in the bubble mat, whereby connector studs are directly plugged into sockets provided in the receptacle and in communication to the partial sections of the bubble mat. The distributor/control switch unit constitutes an easily exchangeable, inexpensive replacement part.
