  • 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.

  • Patent number: 8479326
    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.

    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: 5740567
    Abstract: A blanket with waterproof frictional backing comprising an upper layer attached to a lower layer, and frictional strips attached to the lower layer. The upper layer is a non-abrasive textile such as canvas or terrycloth, and is intended to provide a comfortable seating surface for an occupant. The lower layer is a waterproof material such as plastic or nylon, and serves to protect an occupant from a wet surface upon which the blanket with waterproof frictional backing rests. The frictional strips are fabricated of a material such as rubber or other suitable material, and are intended to prevent the blanket with waterproof frictional backing from slipping on a wet surface, thus enhancing the comfort of an occupant as well as decreasing safety risk.

  • Patent number: 5638558
    Abstract: A pad is located on a bed between a human patient and the bed sheet. The pad has a slick, smooth bottom wall, such as satin. The bottom wall reduces the friction between the pad and the bed sheet, whereby the patient together with the pad can be smoothly moved on the bed or off of the bed and onto a waiting gurney. The pad has a top wall and padding interposed between the top and bottom walls, the layers joined together with channels of quilting stitches and digital eyelets which prevent caregivers accidentally dropping a patient when the patient is being moved to or from a bed/gurney, or turned, the pad is made of materials which are permeable to air and dissipate body perspiration and bodily fluids, thus promoting sanitation and can be position under the patient for indefinite periods of time to reduce the incidence of bed sores.

  • Patent number: 5632051
    Abstract: The invention is a cooling pillow container insert which provides a continuous cool pillow surface and absorbs a pillow user's lost metabolic heat. Preventing thermal discomfort which causes pillow flipping and tossing and turning is the primary goal of the invention. The container slides between a conventional pillow and pillow case. The container is composed of a soft vinyl bag which snugly surrounds a fluid saturated porous foam core. A resealable valve allows fluid to be added or removed at will and the container's temperature to be adjusted. The container promotes heat transfer from the pillow user to the container. The heat is then dispersed uniformly throughout the container's fluid ensuring a uniformly cool pillow surface. Heat is also continuously lost to the surrounding environment. A pillow user's sleep is enhanced in warm temperatures without using an energy source. The container insert can also be used with or without a pillow, as a cooling bed for an animal or a pet.

  • Patent number: 5621931
    Abstract: A bedskirt assembly made up of a non-slip grip deck made from non-slip fabric with releasable fasteners. The grip deck is installed between the mattress and box springs of the bed and stabilizes the location of the mattress relative to the box springs and provides for easy attachment of segments of skirting, in one panel or several panels. The position of the panels is adjustable for height and length and to suit individual bedframes. The skirt panels can be quickly and easily removed and replaced without having to remove the mattress from the box springs.

  • Patent number: 5542137
    Abstract: A contour skirt for mattress pads or covers and the like is provided with a high friction inner surface to hold the pad or sheet firmly in place on a mattress. Foam material such as polyurethane may be stitched to the inner surface of the skirt in a pattern that produces "puffs" of foam that act as "treads" to grip the mattress. Alternatively, high friction polymeric material such as latex or neoprene may be bonded in strips to the inner surface of the skirt.

  • Patent number: 5471689
    Abstract: The bed handle system of the present invention, which includes a pair of handle elements, is used for facilitating movement into and out of a bed. Each handle element can be anchored to a bed mattress and has an upwardly extending handle section dimensioned to extend above the bed mattress. In use the handle portion is positioned adjacent a first side of the mattress, and the pair of handle elements are positioned in spaced relation to each other. The spacing between the handle elements may be adjusted to permit a user to grasp one handle section with each hand and to sit between the elements on the mattress preparatory to moving into or out of the bed.
