Description
-- 104~;~72 ~ackqround of the Invention Field of the Invention The present invention relates to an improved draw sheet for bedding, and more particularly, but not by way of limitation, to an improved draw ~heet having a removable and launderable water-absorbent pad attached thereto.
DescriPtion of the Prior art Many various combinations of bedding have been utilized in hospitals and the like to prevent water and other fluids deposited on the bedding from penetrating and causing damage to mattresses, etc. For example, rubber, plastic and other waterproof materials in the form of sheets have been utilized over the mattres~ beneath textile ~heets or other bedding materials. While such waterproof sheets successfully prevent water and other fluids from reaching the mattress, they cause considerable discomfort to the person or patient disposed on the bedding due to the poor heat transfer characteristics of such materials. That i~, heat and moisture generated by the patient are retained adjacent the patient's body causing considerable discomfort, particularly when such patient is required to remain on the bedding for long period~ of time.
In addition, the textile sheets and other bedding materials placed on top of such waterproof sheets must be laundered frequently.
Recently, disposable water-abosrbent pads have been developed and used which are formed of relatively thick water-ab~orbent materials and which have a waterproof base formed of a plastic material 3uch as polyethylene. In use, such water-absorbent pads are placed on top of the bedding directly beneath the patient disposed on the bedding whereby the pad can be replaced and dis-- 104~;172 oosed of when required without the nece~sity of changing and laundering textile sheets and other bedding materials utilized on the bed. While the frequent change of such disposable water-absorbent pads can prevent ~ubstantial discomfort to the patient, the w~e of ~uch pads in many ca~es i~ ineffective in that they readily become dislodged from beneath the patient or otherwise allow fluids to reach the bedding resulting in the requirement that the bedding be changed. More importantly, the use of such disposable pads involves a considerable expense in that the pads are not reusable.
In addition to the foregoing, a variety of water penetration-resistant draw sheets have been developed and used, some of which have relatively good heat transfer characteristics and thereby obviate patient discomfort, but all of which must be changed and laundered on a frequent basi~ in order to prevent the accumulation of fluids directly beneath the patient.
By the present invention an improved bedding draw sheet is provided which can be utilized directly beneath a patient on top of other bedding materials, which prevents the penetration of water and other fluids into the bedding materials, which has good heat transfer characteristics, and which includes a removable water-absorbent pad portion which can be changed and laundered when required without changing and laundering the entire draw ; sheet or other bedding materials associated thereWith.
Summarv of the Invention The present invention relates to an improved draw sheet for bedding which comprises a base sheet formed of textile materials, a panel bonded to the base sheet formed of a fine weave textile 104~
material having water penetration-resistant characteristics, a water-ab~orbent pad positioned adjacent the panel and means for remo~ably attaching the water-ab~orbent pad connected to the pad and the panel.
It is, therefore, a general object of the present invention to provide an improved bedding draw sheet.
A further object of the present invention is the provision of a bedding draw sheet which prevents the penetration of water and other fluids into the bedding material lying beneath the draw sheet, but still has good heat transfer characteristics.
Yet a further object of the present invention is the pro-vision of an improved draw sheet which includes a water-absorbent portion which can be replaced and laundered at freguent intervals without the necessity of changing and laundering the entire draw 5heet or other bedding materials associated therewith.
Other and further objects, features and advantages of the invention will be readily apparent from a reading of the description of preferred embodiments which follows when taken in conjunction with the accompanying drawing.
Brief Description of the Drawinq Figure 1 is a perspective view of a bed having the improvea draw sheet of the present invention installed thereon.
Figure 2 is a top view of the improved draw sheet of this invention.
FigUre 3 is a cross-sectional view taken along line 3-3 of Figure 2.
DescriPtion of Preferred Embodiments Referring now ts the drawing, and particularly to Figure 1, a bed generally designated by the numeral 10 is illustrated. The bed 10 is comprised of the usual box springs or equivalent means 12 having a mattre~s 14 disposed thereon. Positioned on top of the mattress 14 is the usual textile sheet 16 upon which a per-son dlsposed on the bed lies. As will be understood, any number of other conventional bedding materials, such as mattress covers, etc., can be utilized between the sheet 16 and mattress 14. The customary pillow 18 upon which a person disposed on the bed places his head i8 shown at one end of the bed 10. The improved draw sheet of the present invention, generally designated by the numeral 20, is po~itioned on top of the sheet 16 at a point substantially intermediate the ends of the bed 10.
The draw sheet 20 can take a variety of forms, e.g., the form illustrated whereby it cover~ only an intermediate portion of the sheet 16 and mattress 14, or the draw sheet 20 can be of the same size as the textile sheet 16. In a preferred embodiment, the draw sheet 20 is rectangular in shape having a length such that the end portions 22 and 24 thereof can be disposed around the sides of the mattress 14 and tucked therebeneath, and a width such ~hat when disposea on the bed 10 as illustrated in Figure 1, the portion of the bed 10 and bedding materials lying beneath the intermediate portion of a patient's body disposed on the bed are covered thereby. As best shown in Figure 3, the improved draw sheet 20 includes a base portion or sheet 26 which can be formed from any of a variety of conventional launderable textile materials of the type generally utilized for bedding, i.e., tex-tile materials or fabrics which have good heat transfer and com-fort characteristics as well as good launderability such as 50%
10~6172 cotton-50% polye~ter textile materials. A panel 28 formed of a textile material or fabric having water penetration resistance, but ~till having good heat transfer characteristics and launder-abil~ty i8 po~ltioned adjacent and bonded to the top ~urface of the base sheet 26. While the paneI 28 can be of the same shape and æize as the base ~heet 26, it is preferably of rectangular shape and of reduced size as compared to the base sheet 26. That is, the panel 28 is of a smaller size than the base sheet 26 but of a length and width such that the area of the bed 10 which normally lies beneath the intermediate portion of a patient's body disposed on the bed 10 is covered thereby.
The panel 28 is bonded to the base sheet 26 in a manner such that the base sheet 26 and panel 28 retain their flexibility, launderability and good heat transfer characteristic~. Thi~ is accomplished in accordance with the present invention by inter-posing between the base sheet 26 and the panel 28 a thin layer 30 of a binder which upon setting is flexible and adheres to the -surfaces of the textile materials 26 and 28 for long period~ of time without degradation from the subjection to moisture and high temperatures associated with the laundry of the draw sheet 20.
A particularly preferre~ binder for use in accordance with the present invention is a thermally settable plastic ha~ing char-acteristics such that it is impervious to contact with acid or alkaline fluids and high temperatures. The most preferred such thermalplastic is polyethylene.
As stated above, the panel 28 is preferably formed of a water-resistant textile material having good flexibility and heat transfer characteristics. Suitable such materials are finely - ~04617Z
woven fabrics formed of cotton and/or synthetic fibers. A
particularly suitable fabric which i8 presently preferred for use in accordance with the present invention i~ a cotton fabric having a thread count in the range of from about 264 threads per inch to about 280 threads per inch.
Po~itioned on top of the panel 28 is a pad 32 formed of water-absorbent materials having good comfort and heat transfer characteristics as well as good launderability. Preferably, the pad 32 is formed of a soft commercially available felt material having high water-absorbing properties. While the pad 32 can take a variety of shapes, it is preferably rectangular and of a size corre~ponding to the panel 28.
The pad 32 is removably attached to the panel 28 so that it is retained over the panel 28 during use of the draw sheet 20.
Any of a variety of fastening methods or connector and fastener devices ~an be utilized 80 long as the pad 32 remains relatively flat whereby discomfort is not caused a patient lying thereon.
Particularly suitable means for removably attaching the pad 32 to the panel 28 comprise a pair of elongated strips of material 32 to which felt adheres stitched or otherwise connected to opposite ends of the panel 28 positioned parallel to the sides of the bed 10. A particularly preferred such adhesive material which with-stands repeated laundering, etc., is marketed under the trade name VELCRO and includes a plurality of upwardly extending plastic barbed fingers which readily engage felt and other similar materials.
Operation In operation or use of the improved draw sheet 20 of the 104~;1'72 present invention, the draw sheet is placed on top of other bedding used on a bed and positioned so that the wator-absorbent pad 32 and panel 28 lie beneath the intermediate portion of the pati~nt's body occupying the bed. At intervals when the water-absorbent pad 32 bocomes saturated with fluid or otherwise ~oiled, the pad 32 is detached from the draw sheet 20 and replaced with a fre~h, laundered pad. Because the panel 28 beneath the pad 32 resists penetration by water, it is unnecessary to change the entire draw sheet 20 each time the water-absorbent pad 32 i9 .
changed. If the pad 32 becomes saturated with fluids prior to changing, and as a result, excess fluids accumulate on the panel 28, such excess fluids can simply be toweled up prior to installing a fresh and dry pad 32 thereon.
The draw sheet 20 has principal utility for u~e in hospitals and the like where it i~ subjected to frequent deposits of water and other fluids. In such applications, the water-absorbent pad 32 can be changed frequently and laundered without the necessity of changing the entire draw sheet 20 or any of the other bedding materials utilized therebeneath in a fast, efficient manner. In addition, because the water-absorbent pad 32 as well as the en-tire draw sheet 20 are launderableO they can be subjected to repeated use over long periods of time while retaining good heat transfer and other health and comfort characteristics.
As will be understood by those skilled in the art, the draw sheet of the present invention and the component parts thereof can take any of a variety of shapes and sizes and various textile materials can be utilized. For example, the panel 28 can be con-tiguous with the base sheet 26 and/or the base sheet 26 and panel ~04~7Z
28 can be formed of the same or different fabrics. Such sizes, shapes and materials will suggest themselves to those skilled in the art upon a reading of the foregoing description of the inven-tion, a~ will change~ in the arrangement of the various components of the invention, which are within the spirit of this invention as defined by the lawful scope of the appended claims.
