  • Patent number: 8978178
    Abstract: The present invention relates to a fabric arrangement and pillow designed to prevent skin lines and wrinkle formation while improving sleep using combinations of fabrics, cooling technologies and scents. The present invention is designed with a specific fabric and materials combination that create a surface in which the shear stresses causing skin lines and wrinkles are eliminated. Multiple layers make up the fabric arrangement include a top layer comprising a stretchable material and a second layer comprising a low friction material relative to the first layer. Supporting the first two layer is a support layer such as foam. Lower layers may comprise a cooling material, an antimicrobial or anti-allergenic material and a scent layer.

  • Patent number: 8850634
    Abstract: A device for use with a bed having a frame and a supporting surface includes a flexible sheet with a tether strap connected to the sheet and extending from the sheet. The flexible sheet has opposed top and bottom surfaces, with the top surface having a high friction material with a higher coefficient of friction as compared to the bottom surface, which includes a low friction material. The tether strap is configured for connection to the frame of the bed to secure the sheet in place. A system incorporating the flexible sheet may also include an absorbent pad configured to be placed on the top surface of the sheet, where the high-friction top surface resists sliding of the absorbent pad, as well as one or more wedges having a base wall that the wedge rests on and a ramp surface configured to confront the sheet when the wedge is placed under the sheet. The base wall and the ramp surface may also contain high friction and low friction materials, respectively.

  • Patent number: 8601624
    Abstract: This invention relates to mattresses such as a pressure relieving mattress and in particular ones for profiling beds. The mattress comprises a base portion 11, a carriage portion 12, an upper portion 13 and an inflatable pressure relieving underlay 14 disposed between the carriage 12 and the upper portion 13. The facing surfaces 15 and 16 of the base portion 11 and the carriage portion 12, respectively, are coated with a low friction material so that the two slide easily relative to one another. This sliding movement is restricted to longitudinal relative movement by the engagement of co-operating formations 17, 18. The combination provides particularly flexible mattress arrangement which also avoids the problem of the leg section of the mattress kicking upwardly when a profiling bed is articulated.

    Abstract: Disclosed is a physical therapy support, comprising a planar structure having a first and second end and an upper and lower surface that reduces friction between the lower body of a patient and a hospital bed. The device is positioned between a patient's hips and the underlying bed sheets, whereby the patient is elevated and separated from the sheets to allow freedom of movement and increased support when engaging in hip and lower body movements for recovery and physical therapy sessions. The shape of the device includes a first rounded end and a second flat end to form a triangular shape having tapering longitudinal sides. The cross section comprises a thin, rigid and uniform material having a low friction upper surface and a high friction lower surface. A slot penetration along the one of the tapering sides allows for handling of the device and for transporting between patients.

The baby hairapy pad is a stain-resistant, satin-covered foam and cotton/polyester pad designed to minimize hair breakage, loss, and tangling, help maintain scalp moisture balance, and protect hairstyles in infants and toddlers. Unlike pillows and linens with satin cases or aromatherapy pillows, its foam and cotton/polyester interior is both thin and firm to be safe for infants. Further, it is small and flexible enough to be easily transported and used in multiple areas: cribs, beds, carriers, floors, strollers, etc. Plus, it provides for the options to include the soothing, calming scents of chamomile and lavender within it and to use it as a nursing pad for breastfeeding mothers and their babies.

  • Patent number: 7240384
    Abstract: The patient positioning aid assists a caregiver in rotating and positioning immobile patients. Such patients require periodic movement to prevent the development of ulcers. Conventional methods use rolled blankets or pillows to support such patients. Such improvizations are often crushed by the patients, especially by bariatric patients. The present invention has a strong resilient foam core which resists compression by a patient, yet also has a yielding surface foam layer which avoids trauma to the patient's skin. The cover is removable for cleaning, waterproof, and utilizes an anti-slip, high friction coating on the bottom which resists sliding on the bed. In addition, handles on the caregiver side of the aid assist in the maneuvering of the aid to position it properly.

  • Patent number: 5280657
    Abstract: A sheet position adjustment assembly comprises a sheet that overlies a support element such as a mattress on a relatively moveable frame of an adjustable bed. A pair of lengthwise adjustable straps connect the sheet adjacent the head portion of the mattress to a relatively stationary base of the adjustable bed. The straps are securely sewn to the sheet by nylon stitching. A mat of reinforcement material is sewn to the sheet at the attachment interface with the straps. A low-friction fabric panel is provided on the underside of the sheet that slides on the mattress. An upstanding rail is attached to the bed frame adjacent the head portion of the mattress to prevent collapse as the connecting straps extend thereover during the position adjustment operation. The method of adjusting the position of the sheet comprises connecting the sheet to the fixed base portion of the adjustable bed. The position of the moveable frame is then vertically adjusted upwardly by lifting or pivoting.

  • Patent number: 5201780
    Abstract: A mattress pad primarily intended for use with a standard hospital bed frame to reduce the development of decubitus ulcers or bed sores in patients using the pad. The pad is multi-layered and includes a cover or casing containing interior strata of a plastic film layer atop a fluid bladder layer supported on an underlying layer of foam. The pad is specially designed to reduce lateral and normal pressures and forces on the patient which can lead to the development of such ulcers. The reduction of the lateral shearing forces is accomplished in a number of ways including by oversizing the plastic film layer and fluid bladder layer on the underlying layer of foam and by positioning microbeads between the plastic film layer and fluid bladder layer to dramatically reduce the frictional drag or lateral shearing forces between the layers.
