Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




Applicant's invention relates to methods and devices to prevent bed soiling. More specifically, Applicant's invention is a waterproof device removably attached to a bed to block body fluid and prevent the fluid from reaching the lower bed sheet and the mattress.




2. Background Information




It is well known certain types of stains, such as blood or urine stains, are difficult to remove. The cleaning job becomes even more difficult if the stained article is large and heavy, such as a mattress. However, bed sheets and mattresses often do become stained if the person resting on the bed is incontinent; if a child sleeping on the bed is prone to bed wetting; or, if the person is a woman, the person is menstruating. Yet it is impractical and too expensive to simply throw away a stained mattress. Further, it is also not economically practical to throw away a set of bed sheets or mattress pad covers every time they become stained.




Since it is impossible or impractical to remove stains by throwing away the bed sheets, the mattress, or the mattress pad cover, an alternate solution is to prevent the lower bed sheet or mattress from becoming stained in the first place. For example, hospitals generally prevent body fluid from reaching the mattress by simply enclosing the entire mattress in a plastic cover and foregoing the mattress pad cover. However, this plastic cover makes the bed extremely hot and uncomfortable to lie on. Further, while plastic covers may prevent mattresses from becoming stained, they do not prevent bed sheets from being stained. Therefore, while hospitals no longer have to replace stained mattresses, they often do have to replace stained sheets. Finally, the plastic covers make it very difficult for the bed sheets to stay securely tucked underneath the mattress. Thus, in addition to being hot and uncomfortable, a hospital patient often has to lie in a bed where the bed sheet covers only half the bed.




Of course, bed sheet and mattress staining do not only occur in hospitals. Children wet beds, people experience incontinence, and women menstruate—all of which may stain bed sheets and mattresses—outside of hospitals. A common way to prevent bed sheet and mattress staining at home is to simply place additional bedding material on the bed, in areas where staining is likely to occur. However, because this bedding material is not secured into place, it tends to bunch up as a person tosses and turns in his or her sleep. Further, bulky bedding material placed on top of bed sheets is uncomfortable. Thus, a person who is incontinent or is menstruating must either risk staining an expensive mattress or expensive bed sheets or endure a relatively thick layer of uncomfortable, additional bedding material in areas where staining is likely to occur.




SUMMARY OF THE INVENTION




It is an object of the present invention to provide a novel device and method that can prevent body fluid from soiling bed sheets or mattresses.




It is another object of the present invention to provide a device that is breathable and comfortable to lie on while preventing body fluid from soiling bed sheets or mattresses.




It is another object of the present invention to provide a device that can be secured in place while preventing body fluid from soiling bed sheets or mattresses.




It is another object of the present invention to provide a device that only covers the area on the bed sheet or mattress that is likely to be soiled by body fluid.




It is another object of the present invention to provide a device that can be easily removed and replaced once it is soiled by body fluid.




It is another object of the present invention to provide a device that can be easily cleaned once soiled by body fluid.




It is another object of the present invention to provide a device and method to prolong the sheet life of bed sheets by having to wash them less requently.




It is another object of the present invention to provide a device that is both decorative and able to prevent body fluid from soiling the bed sheet or mattress.




In satisfaction of these and related objectives, Applicant's present invention provides a stain prevention apparatus that can be secured to a portion of a bed that is most likely to be stained by body fluid. This stain prevention apparatus is generally comprised of a waterproof panel, a panel anchor, and two tuck panels. In the preferred embodiment of the present invention, the waterproof panel is a generally rectangular bedding having an upper layer and a lower layer made of cloth, with a waterproof layer secured to and sandwiched between the upper layer and the lower layer. The waterproof panel is removably attached to a panel anchor. The panel anchor is made of cloth and is of the same general dimensions as the waterproof panel. Two tuck panels, one attached to each side of the panel anchor, are used to secure the stain prevention apparatus to the mattress.




To practice Applicant's invention, a practitioner first tucks both tuck panels underneath the mattress while making sure the area covered by the stain prevention apparatus is in the same general area where the person lying on the bed is most likely to soil the bed sheet or mattress. The waterproof panel can be attached to the panel anchor either before or after the panel tucking step. Thereafter, the person lies on the bed. After the stain prevention apparatus has been soiled, the practitioner removes the waterproof panel from the panel anchor. The waterproof panel is then washed. A replacement waterproof panel without stains can be attached to the panel anchor while the first waterproof panel is being cleaned.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT





FIG. 1

shows a preferred embodiment of a stain prevention apparatus


10


being used by a practitioner


20


. Stain prevention apparatus


10


generally consists of a waterproof panel


11


, a panel anchor


12


(shown in FIG.


2


), a first tuck panel


13


, and a second tuck panel


14


(shown in FIG.


2


). Waterproof panel


11


is removably attached to the top of panel anchor


12


(shown in FIG.


2


). First and second tuck panels


13


and


14


(shown in

FIG. 2

) are attached to panel anchor


12


.




To practice the present invention, stain prevention apparatus


10


is spread along the width of a bed


21


, in an area where bed


21


is most likely to be stained. While

FIG. 1

shows first and second tuck panels


13


and


14


(shown in

FIG. 2

) tucked underneath a mattress


22


, as will be discussed below, the present invention may be practiced without tucking first and second tuck panels


13


and


14


underneath mattress


22


. After securing stain prevention apparatus


10


to bed


21


, practitioner


20


simply lies on top of stain prevention apparatus


10


. When stain prevention apparatus


10


is stained, either the entire stain prevention apparatus


10


or only waterproof panel


11


may be removed for cleaning.





FIG. 2

shows a perspective view of panel anchor


12


and first and second tuck panels


13


and


14


. Panel anchor


12


is a generally rectangular piece of material, at least one layer in thickness. In the preferred embodiment, panel anchor


12


is made of cloth. However, panel anchor


12


maybe made of any pliable material. A plurality of buttons


19


are located along the two shorter sides of panel anchor


12


. Buttons


19


are used to secure waterproof panel


11


to panel anchor


12


(See FIG.


4


). While buttons


19


are shown in the preferred embodiment of the present invention, it should be noted that any type of fasteners available in the marketplace such as Velcro® brand fasteners or zippers may be used to attach waterproof panel


11


to panel anchor


12


.





FIG. 2

also shows first tuck panel


13


and second tuck panel


14


attached to panel anchor


12


along the width of panel anchor


12


. While, in the preferred embodiment, first and second tuck panels


13


and


14


are generally rectangular in shape, first and second tuck panels


13


and


14


can be of any shape and size as long as a portion of first and second tuck panels


13


and


14


can be tucked underneath mattress


22


to stabilize stain prevention apparatus


10


. In the preferred embodiment, first and second tuck panels


13


and


14


are made of cloth. However, first and second tuck panel


13


and


14


can be made of any flexible material of any thickness strong enough to prevent stain prevention apparatus


10


from being displaced on bed


21


.




First and second tuck panels


13


and


14


may be removably attached to panel anchor


12


. The ability to detach first and second tuck panels


13


and


14


from panel anchor


12


allows panel anchor


12


to be washed separately from first and second tuck panels


13


and


14


. The removability of first and second tuck panels


13


and


14


from panel anchor


12


prevents first and second tuck panels


13


and


14


from being worn by repeated and unnecessary washing.




In an alternate embodiment, a plurality of small weights (not shown) may be attached or sewn into first and second tuck panels


13


and


14


for additional weight at their respective ends farther from panel anchor


12


. With the weights, practitioner


20


may choose not to tuck first and second tuck panels


13


and


14


underneath mattress


22


and instead use only the weights to keep stain prevention apparatus


10


from being displaced.




Alternate embodiments of the present invention (not shown) may further include additional small weights attached or sewn into the edges of panel anchor


12


, near buttons


19


. These additional small weights will serve as additional means to stabilize and prevent stain prevention apparatus


10


from being moved around bed


21


.





FIG. 3

shows waterproof panel


11


as detached from panel anchor


12


. In the preferred embodiment, waterproof panel


11


is generally rectangular and generally consists of an upper layer


15


, a waterproof layer


16


, and a lower layer


17


. Waterproof layer


16


is sandwiched and secured between upper layer


15


and lower layer


17


. Upper layer


15


and lower layer


17


can be made of any soft, water permeable, breathable, and fluid absorbent material such as cloth. Waterproof layer


16


can be made of any waterproof and preferably washable material available in the marketplace. However, waterproof layer


16


must be made of a pliable material so a person lying on waterproof panel


11


will not experience discomfort caused by the stiffness of waterproof layer


16


.




A plurality of buttonholes


18


are placed along both sides of waterproof panel


11


. Buttonholes


18


are used to attach waterproof panel


11


to panel anchor


12


. While buttonholes


18


are used in the preferred embodiment, it should be noted any method of removably attaching one object to another may be used to attach waterproof panel


11


to panel anchor


12


.




While waterproof panel


11


may be of any size or shape, in the preferred embodiment, waterproof panel


11


is rectangular in shape. Finally, waterproof panel


11


may be decorated with various types of indicia for aesthetic purposes.





FIG. 4

shows a perspective view of stain prevention apparatus


10


just prior to waterproof panel


11


being attached to panel anchor


12


. Waterproof panel


11


is removably attached directly on top of panel anchor


12


by using attaching devices such as buttons


19


and buttonholes


18


.




To practice the present invention, practitioner


20


first spreads stain prevention apparatus


10


along the width of her bed, on an area likely to be stained. Tuck panels


13


and


14


may be tucked underneath mattress


22


. She then lies on the bed, on top of stain prevention apparatus


10


. (See

FIG. 1.

) After stain prevention apparatus


10


is soiled, practitioner


20


simply detaches waterproof panel


11


from panel anchor


12


and washes waterproof panel


11


. Because of waterproof layer


16


, the body fluid, while soiling upper layer


15


, will not reach lower layer


17


. Body fluid will also not reach panel anchor


12


. Therefore, panel anchor


12


will not need to be cleaned. Instead, panel anchor


12


may be left on the bed and a clean replacement waterproof panel


11


may be immediately attached to panel anchor


12


. Alternatively, the entire stain prevention apparatus


10


may be removed and cleaned after waterproof panel


11


is soiled.
