CROSS-REFERENCE TO RELATED APPLICATION

[0001]This application claims priority to U.S. provisional application entitled, "THERAPEUTIC MATTRESS," having Ser. No. 60/756,988, filed Jan. 6, 2006, which is entirely incorporated herein by reference.

FIELD OF THE INVENTION

[0002]The present invention is generally related to a mattress, and more particularly is related to a therapeutic mattress used as a bed or a cushion which reduces pressure and compression forces for non-critical support areas.

BACKGROUND OF THE INVENTION

[0003]Decubitus ulcers, pressure ulcers, pressure sores, bedsores, or other localized tissue damage are risks for persons who are otherwise immobile or bedridden, or left to sit or lie in one position for a period of time. These injuries are at greatest risk to occur in the bony areas of the body, including the back of the head and shoulders, the tailbone region, arms, elbows, hips, heels and feet. The sores can occur with minimal pressure and compression forces, rubbing or friction that causes the deprivation of oxygen and nutrients to tissue, causing the formation of such sores. In some instances, these sores begin as minor skin irritations that are simply exacerbated by the compression, heat and moisture created by the body's weight and the mattress. These injuries can occur in persons of all ages during times of prolonged illness or immobility. The elderly are especially at risk because of the increased likelihood of debilitating medical condition with immobility. The development of these sores can lead to serious infection, which in some cases become life threatening.

[0004]The good news is that these injuries are preventable and such sores do occur, they do not have to get worse. Bedding or other cushioning that reduces or relieves compression effectively addresses the skin's vulnerability to injury. A variety of bedding and cushion arrangements have been proposed to reduce and relieve compression while in use. Generally these bedding and cushioning options include alternate design mattresses, foam, gel, or low pressure inflatable overlays, which lie on top of a regular mattress, or alternating pressure mattresses. However, these bedding and cushioning options are often expensive to implement and have not fully addressed the continuing problem of decubitus ulcers and associated injuries. Therefore, there remains an unaddressed need to address these deficiencies and inadequacies. The present invention is made in consideration of these identified circumstances and it is an object thereof to provide a mattress, as bedding or cushioning, which is economical to implement for the prevention, reduction and healing of decubitus ulcers and associated injuries.

SUMMARY OF THE INVENTION

[0005]The mattress of the present invention has a structure that provides a plurality of support to areas of the body of a user, as critical support areas and utilizes a plurality of voids, as air pouches, in non-critical support areas such as the back of the head and shoulders, the tailbone region, arms, elbows, hips, heels and feet, thereby to prevent, reduce and heal decubitus ulcers. In the preferred embodiment, the mattress is comprised wholly fire-retardant, anti-microbial, variable density foam. The preferred embodiment of the present invention utilizes angular shapes in modular sections for the gradual support maximization in the critical support areas and reduction of pressure and compression force in the non critical support areas. Other systems, methods, features and advantages of the present invention will be or become apparent to one with skill in the art upon examination of the incorporated drawings and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description, be within the scope of the present invention, and be protected by the accompanying claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0012]It is a principle object of the present invention to provide a mattress that is economical to implement for the prevention, reduction and healing of decubitus ulcers and associated injuries. More particularly, it is a principle object of the present invention to provide a therapeutic mattress which provides a plurality of support to areas of the body of a user, as critical support areas and utilizes a plurality of voids, as air pouches, in non-critical support areas such as the back the back of the head and shoulders, the tailbone region, arms, elbows, hips, heels and feet, thereby to prevent, reduce and heal decubitus ulcers.

[0013]Referring now to FIG. 1, a therapeutic mattress 10 of the present invention is shown. To achieve the object of providing an economical mattress for the prevention, reduction and healing of decubitus ulcers and associated injuries, the mattress 10 of the present invention has a top layer 12 and a critical support layer 14, providing pressure and compression force reduction in non critical structure support areas. More specifically, and referring to FIG. 1, a preferred embodiment of the present invention is a therapeutic mattress 10 includes foam top layer 12, which has is substantially rectangular shape as a one piece construction. This top layer 12 has a substantially continuous perimeter comprised of end walls 16, 18 and sidewalls 20, 22. Additionally, the top layer 12 has a foundation body 24 with a downwardly-facing bottom surface 26. The top layer 12 has dimensions similar to any commercially available single user mattress, including any single user mattress used by the medical community. In the preferred embodiment 10 of FIG. 1, the bottom surface 26 of the foundation body 24 comprising the top layer 12 is approximately 80 inches long as the horizontal length of the side walls 20, 22 and 36 inches wide as the horizontal length of the end walls 16, 18. The thickness of the foundation body 24 comprising the top layer 12 is dependent on actual use and can range from 0 inches to 8 inches, but is preferably approximately 2 inches. The top layer 12 is preferably comprised of durable, fire-retardant, anti-microbial foam, but it is conceived that another material capable of providing support to a user could be utilized in construction. The density of the foam of the top layer 12 is dependent on expected and actual use and can range from 1.0 lb. per cubic foot density foam to 5.8 lb. per cubic foot density foam, but is preferably approximately 1.8 lb. per cubic foot density foam. The top layer 12 has an upwardly-facing top surface, with contour which is preferably smooth, but may be of any of slashed, smooth, egg crate or any other design known in the industry.

[0014]The top layer 12 is in combination with the critical support layer 14 to form the mattress 10. Referring now to FIG. 5, it is also envisioned that in an alternate embodiment, a base layer 80 could be fixed firmly with direct contact with the critical support layer 14, as an intermediate layer in direct contact with the top layer 12, to form the mattress 10. In yet additional alternate embodiments, not represented by drawings, the mattress of the present invention could be made with solely a base layer 80 and the critical support layer 14, as disclosed or solely the critical support layer 14. The thickness of the base layer 80 is dependent on actual use and can range from 0 inches to 8 inches, but is preferably approximately 2 inches. The base layer 80 is preferably comprised of durable, fire-retardant, anti-microbial foam, but it is conceived that another material capable of providing support to a user could be utilized in construction. In the preferred embodiment of FIG. 1 and the alternate embodiment of FIG. 5, the mattress 10 is optionally encased in a removable waterproof and anti-microbial cover.

[0015]As shown in FIG. 4, the critical support layer 14 is fixed firmly with direct contact to the bottom surface 26 of the foundation body 24 with a means sufficient to prevent or reduce shifting between the critical support layer 14 and the top layer 12, after they have been aligned. The affixing of the critical support layer 14 to the bottom surface 26 of the foundation body 24 can occur by numerous means, including bonding during construction process by an adhesive agent known in the industry. Alignment between the critical support layer 14 and the top layer 12 results when the critical support layer 14 is substantially configured to the dimensions of the top layer 12. Additionally, it is conceived that the top layer 12 and the critical support layer 14 could be a unified piece, wherein the detail of the critical support layer 14 is made by cuts during the construction process.

[0016]Referring now to FIGS. 2 and 3, the critical support layer 14 is further comprised of a plurality of support zones 28, 30, 32, which provide support to the body of a user. The support zones 28, 30, 32 can act independent or in concert. The support zones 28, 30, 32 are preferably comprised of durable, fire-retardant, anti-microbial foam, but it is conceived that another material capable of providing support to a user could be utilized in construction. The density of the foam of the support zones 28, 30, 32 is dependent on expected and actual use and can range from 1.0 lb. per cubic foot density foam to 5.8 lb. per cubic foot density foam, but is preferably approximately 1.8 lb. per cubic foot density foam. The foam density of the top layer 12 and the support zones 14 do not need to be the same. Additionally, the foam density need not be uniform in any or all or support zones 28, 30 and 32. Support zones 28, 30 and 32 are comprised of angular shapes to achieve critical support. In the preferred embodiment shown in FIGS. 1, 2 and 3, these shapes are substantially formed to triangles, squares and rectangles, however the present invention conceives that any angular shape can be implemented with the zone configuration for proper support to critical areas and creation of the pressure and compression force reduction zones in non-critical support areas. As shown in FIG. 2, the upper surfaces 28a, 30a, 32a of the support zones 28, 30, 32 have contour, which is preferably smooth, but may be any of slashed, smooth, egg crate or any other design known in the industry.
