Abstract
A machine washable wedge shaped support structure is formed from a fabric envelope loosely filled with lightweight, preferably polystyrene, beads which shape it. The fabric may have a non-skid surface to resist sliding in use. The wedge conforms to a patient's or infant's body. When compressed, the fabric envelope and beads lock into a roll-preventing support structure. One alternate version has a stabilizing panel extending from the pointed end of the wedge on which a patient lies. Another version has a connecting panel between two opposing triangular shaped wedges. It provides roll preventing support for a pregnant woman and doubles as an anti-roll pad for infants.
Claims20
A freestanding machine washable wedge shaped support structure for use as a roll-preventing, patient support, comprising:
- an open mesh fabric base panel defined by spaced apart substantially parallel longitudinal edge portions and transverse edge portions between the ends of said longitudinal edge portions;
- a pair of open mesh non-skid fabric support panels having longitudinal edge portions coextensive with the longitudinal edges of the base panel, said panels converging toward each other to meet at a longitudinal front edge spaced away from said longitudinal edge portions, each of said support panels having transverse edge portions extending between ends of one of said longitudinal edge portions and said front edge;
- opposite triangular shaped open mesh fabric side panels, each side panel having a base edge coextensive with one transverse edge of the base panel and converging side edges coextensive with the transverse edge portions of the pair of support panels extending between said base panel and said front longitudinal edge portion to form an envelope;
- and
- a multiplicity of discrete lightweight nonabsorbent plastic floatable foam beads contained within the envelope by said open mesh fabric to form a wedge, substantially filling said envelope to a degree that allows free movement of said beads within the envelope so that the wedge can be molded to fit the contour of the patient's body, yet having the characteristic that when the envelope and plastic beads are compressed by a patient's weight, they interact to lock together in the previously molded shape to provide a firm support which restricts movement of the patient and allows circulation of air and moisture to help keep the patient dry

A machine washable roll preventing support structure for use as a roll preventing patient support comprising:
- a fabric base panel defined by spaced apart substantially parallel longitudinal edge portions and transverse edge portions between the ends of said longitudinal edge portions;
- a pair of fabric support panels having longitudinal edge portions coextensive with the longitudinal edges of the base panel, said support panels converging toward each other to meet at a longitudinal front edge portion spaced away from said base panel, each of said support panels having side edge portions extending between one of the ends of the longitudinal edge portions of the base panel and said front edge portion;
- opposite fabric side panels, each side panel having edges coextensive with each of the side edges of the support panels and a transverse edge of the base panel, having a triangular shape and together with the support panels and base panel forming a fillable wedge shaped fabric enclosure;
- a multiplicity of discrete lightweight nonabsorbent plastic floatable foam beads contained within the wedge shaped fabric enclosure to form a wedge, substantially filling said enclosure to a degree that allows free movement of said beads within the fabric enclosure so that the wedge can be molded to fit the contour of the patient's body, yet having the characteristic that when the fabric enclosure and plastic beads are compressed by a patient's weight, they interact to lock together in the previously molded shape to provide a firm support which restricts movement of the patient, and
- at least one fabric extension panel extending from said front edge portion a substantial distance away therefrom to form a stabilizing pad for placing under a patient to help hold the wedge shaped support in place.

A combination machine washable roll preventing support structure for a pregnant woman which doubles as a baby changing pad, comprising:
- a first fillable wedge shaped fabric support structure defined by a fabric envelope having a triangular cross section and upper and lower support panels converging to meet a pointed edge of the first fillable wedge;
- an opposite second fillable wedge shaped fabric support structure defined by a fabric envelope having a triangular cross section and upper and lower support panels converging to meet at a pointed edge of the second fillable wedge;
- a multiplicity of discrete lightweight nonabsorbent plastic floatable foam beads contained within the fabric envelope to form first and second wedges, substantially filling said envelopes to a degree that allows free movement of said beads within said fabric envelopes so that each wedge can be molded to fit the contour of the patient's body, yet having the characteristic that when the fabric envelope and plastic beads are compressed by a patient's weight, they interact to lock together in the previously molded shape to provide a first support which restricts movement of the patient, and
- a flat connecting panel connecting the pointed edges of the oppositely arranged first and second wedge shaped support structures of a length chosen to hold said first and second wedges cradled against the front and back of a pregnant woman lying on her side in partial support thereof and usable after delivery as a baby's changing pad to prevent a baby from rolling off a surface.

The combination of claim 18 wherein the beads have variation in size of about at least an order of magnitude for purposes of good close packing characteristics.
A freestanding machine washable wedge shaped support structure for use in positioning a patient on a support surface comprising:
- an elongated wedge shaped envelope having a generally triangular cross-section, said envelope having a base panel for placing on a patient support surface and an opposite support panel for contact with a patient;
- said wedge shaped envelope being an open mesh fabric having a non-skid surface on at least said base panel, for inhibiting slippage when in contact with a patient support surface, said fabric having visible air and water permeable openings;
- a multiplicity of discrete lightweight nonabsorbent plastic foam beads contained within the envelope by said open mesh fabric to form a wedge, substantially filling said envelope to a degree that allows free movement of said beads within the envelope so that the wedge can be molded to fit the contour of the patient's body, yet having the characteristic that when the envelope and plastic beads are compressed by a patient's weight, they interact to lock together in the previously molded shape to provide a firm support which restricts movement of the patient;
- and
- the combination of the open mesh fabric and discrete lightweight nonabsorbent plastic beads being able to provide free flow of moisture and air through the structure to facilitate quick drying.
