DETAILED DESCRIPTION OF THE INVENTION

(36) The presently preferred embodiments of the described invention will be best understood by reference to the Figures, wherein like reference numbers indicate identical or functionally similar elements. It will be readily understood that the components of the present invention, as generally described and illustrated in the Figures, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description, as represented in FIGS. 1 through 17B, is not intended to limit the scope of the invention as claimed, but is merely representative of some presently preferred embodiments of the invention.

(37) According to some embodiments, a bed sheet may have handles that are secured to the bed sheet using an integrated webbing that allows the bed sheet to be used to transport patients from a bed to another location. The integrated webbing strengthens the interface between the handles and the top portion of the bed sheet so that patients of substantial weight can be transported within the bed sheet.

(38) As used herein, the term bed is understood to describe any surface that is capable of supporting a body, and for which it is customary to cover the surface with a sheet or other type of protective material. For example, the term bed may include a gurney, a stretcher, a table, an examination table, an operating table, a bed, or other similar surface. Further, the term bed sheet as herein is understood to describe generally any sheet or other type of protective material that is used to cover at least a portion of a bed, as described herein.

(39) FIG. 1 illustrates a first example of a bed sheet 100 that is configured in accordance with one or more embodiments of the present invention. As shown, bed sheet 100 includes a top portion 101 (i.e., the portion on which the patient lays) and a sidewall 102 that is connected along the edges of top portion 101. Bed sheet 100 is therefore an example of a fitted sheet. It is noted, however, that a bed sheet in accordance with embodiments of the present invention can also be configured as a flat sheet. In such embodiments, the depicted sidewall 102 can be viewed as the periphery of top portion 101. Accordingly, the present invention should not be limited to a fitted sheet.

(40) Some embodiments of bed sheet 100 comprise a top portion 101 consisting of a single layer. In other embodiments, bed sheet 100 comprises two or more layers of top portion 101, wherein the additional layers increase the overall strength of top portion 101.

(41) For purposes of this specification and the claims, the sides of the bed sheet should be construed as the portions of the bed sheet that would be positioned along the sides of a bed. Similarly, the ends of the bed sheet should be construed as the portions of the bed sheet that would be positioned along the head and foot of the bed. In a typical-sized hospital bed, the sides of the sheet would be longer than the top and bottom of the sheet. However, a bed sheet in accordance with embodiments of the present invention should not be limited to any particular size.

(42) As shown in FIG. 1, bed sheet 100 includes four pairs of handles 104. Each handle 104 is secured to the underside of top portion 101 as indicated by handles 104 being drawn in phantom. Accordingly, to expose handles 104 for use, sidewall 102 could be lifted up away from the sides of the bed. Once handles 104 are exposed, medical personnel (or other individuals) could use handles 104 to lift the patient (or other individual) while the patient is contained within top portion 101.

(43) To allow bed sheet 100 to be used to transport a patient, bed sheet 100 can include a webbing 103 that reinforces the connection between handles 104 and top portion 101. FIG. 1A illustrates an example of how webbing 103 could be integrated into bed sheet 100. In FIG. 1A, bed sheet 100 is shown without top portion 101 to allow webbing 103 to be seen. As shown, webbing 103 comprises strips of material that extend along the sides of top portion 101. Webbing 103 can be attached to top portion 101 in any suitable manner. For example, webbing 103 may typically be sewn to top portion 101 along the length of top portion 101 to ensure a strong connection.

(44) FIG. 1A also shows that a top portion of handles 104 is secured to webbing 103. For example, the portion of handles 104 may be sewn on top of webbing 103. In this way, handles 104 can be strongly secured to top portion 101 via top portion 101's connection to webbing 103. In the depicted embodiment, webbing 103 is shown as extending the full length of top portion 101 which can enhance the distribution of weight along the length of top portion 101 thereby minimizing the likelihood that top portion 101 may rip during transport of a patient.

(45) FIG. 1B illustrates bed sheet 100 with sidewall 102 removed. As shown, handles 104 are configured as loops. These loops are configured such that they will be covered by sidewall 102 when bed sheet 100 is placed on a bed. In this way, handles 104 are less likely to catch on a structure when a bed is transported but remain easily accessible by simply lifting up sidewall 102. The loop shape of handles 104 can facilitate lifting of a patient without placing excessive strain on the hands or wrists of the medical personnel or other lifter. In particular, the medical personnel (of which, in this embodiment, there would be four) may insert their wrists and/or hands through the loop portion of handles 104. The loop portion of handles 104 may then be secured around the wrists and/or hand so that weight is more evenly distributed towards the larger muscles of the upper arms. This is in contrast to simply grabbing a portion of the bed sheet in the hands, which places excessive force on the fingers and wrist. Accordingly, the loop-shaped design of handles 104 can facilitate lifting while also minimizing the risk of injury.

(46) Also, because handles 104 are positioned in pairs, the weight can be more evenly distributed between both arms. In some embodiments, a pair of handles 104 may be spaced close enough to allow the medical personnel to insert each arm in opposite directions through both handles so that the weight can be supported by the overlapping forearms. In this way, a large portion of the weight can be supported by the shoulders and biceps of the medical personnel. It is noted, however, that the present invention also extends to embodiments where handles 104 are not positioned in pairs. For example, bed sheet 100 could alternatively be configured with four handles 104 with one handle at each corner of the bed sheet.

(47) FIGS. 1C and 1D each illustrate different layerings of components of bed sheet 100. It is noted that these figures are not drawn to scale. In FIG. 1C, handle 104 is shown as being sandwiched between sidewall 102 and webbing 103. Although sidewall 102 is shown as extending under top portion 101 the same distance as the other components, sidewall 102 could equally extend a shorter distance. Also, sidewall 102 could also be secured to the top side of top portion 101. In any case, the manner in which sidewall 102 is secured to top portion 101 is not essential to the invention. Further, in embodiments where bed sheet 100 is a flat sheet, sidewall 102 would not be a separate component than top portion 101. FIG. 1D illustrates an alternate layering in which handles 104 are secured to the underside of webbing 103. It is noted that these are merely two example layerings and any suitable layering could be employed. Also, the distances to which handles 104 and webbing 103 extend into the interior of top portion 101 could differ. For example, webbing 103 could be wider or narrower than is shown in FIGS. 1C and 1D. Preferably, webbing 103 would have a width/area sufficient to allow the full length of the top portion of handles 104 to be secured thereto.

(48) FIG. 2 illustrates another embodiment of a bed sheet 200 having handles 104. Bed sheet 200 is similar to bed sheet 100 except that sidewall 102 of bedsheet 200 includes one or more vents 201. Vents 201 can be positioned within sidewall 102 so as to align with corresponding vents formed in a mattress on which bed sheet 200 may be placed. As such, vents 201 prevent air from becoming trapped between bedsheet 200 and the mattress.

(49) FIG. 3 illustrates another embodiment of a bed sheet 300 having handles 104. Bed sheet 300 is similar to bed sheet 100 except that bed sheet 300 includes a netting 301 that extends underneath top portion 101 (which is not shown to allow the underlying components to be visible). Netting 301 can be used to reinforce top portion 101 of bed sheet 300 thereby allowing bed sheet 300 to be used to transport patients of significant weight.

(50) FIGS. 3A and 3B illustrate two possible ways in which netting 301 could be secured to top portion 101. In FIG. 3A, netting 301 is shown as being secured between top portion 101/sidewall 102 and handles 104/webbing 103. In contrast, in FIG. 3B, netting 301 is shown as being positioned underneath webbing 103. Alternatively, netting 301 may be positioned directly underneath top portion 101. In any layering, netting 301 can be secured to webbing 103 so that the combination of webbing 103 and netting 301 can provide substantial reinforcement to top portion 101. In some embodiments, a single stitch may be employed to secure each component depicted in FIGS. 3A and 3B or FIGS. 1C and 1D (e.g., by sewing through all components at the same time). In other embodiments, multiple stitches may be employed (e.g., by first combining subsets of the components and then combining the subsets).

(51) In some embodiments, some of the components of the bed sheet may be made of different materials. For example, in some instances various components of the bed sheet may be recyclable, and other various components may be biodegradable. In other embodiments, the various components of the bed sheet may comprise different types of recyclable materials for which separation and sorting is required prior to recycling. Accordingly, to facilitate disposing of the bed sheet, the components may be interconnected in a manner that facilitates separation of the components. For example, a chain stitch (which is commonly used on sacks of food products, such as flour or dog food) can be employed. In such cases, a tab or other structure can be secured to the end of the stitch to facilitate the removal of the stitch and the separation of components. In this way, the components of different materials can be separated and disposed of properly such as by separating the different materials according to their recycling codes and/or by separating biodegradable materials from recyclable materials.

(52) In some embodiments, top portion 101 (and possibly sidewall 102) can be formed of a polyester-based material or of a biodegradable material (e.g., a cotton-based material) while the remaining components (i.e., webbing 103, handles 104, netting 301, and possibly sidewall 102) can be formed of a polypropylene material. In such cases, top portion 101 can be configured to be easily separated from the other components for independent recycling. In some embodiments, at least some of the components (including top portion 101) can be formed of lyocell (which is the generic term for Tencel) or other similar biodegradable material. Polypropylene may be used for webbing 103 and netting 301 due to its strength. In some embodiments, the webbing 103 and/or the netting 301 may include one or more of the following: polyamide, nylon, polyester, and polypropylene. In some embodiments, handles 104 may be formed of a rubber material.

(53) In some embodiments, the materials of the bed sheet are selected to provide a single-use bedsheet. In other embodiments, the materials of the bed sheet are selected to provide a reusable bed sheet.

(54) FIG. 4 illustrates another embodiment of a bed sheet 400 that includes handles 104 positioned along the ends of top portion 101. In this embodiment, up to eight medical personnel could each lift bed sheet 400 using a pair of handles 104. As shown in FIG. 4A, which illustrates bed sheet 400 with top portion 101 removed, webbing 103 can extend fully around the periphery of top portion 101 to allow each pair of handles 104 to be secured to webbing 103. Although webbing 103 is shown as a continuous piece of material, multiple pieces of material could be used to form webbing 103. However, if multiple pieces of webbing 103 are employed, it would be preferable to interconnect the multiple pieces to provide a stronger reinforced structure underneath top portion 101.

(55) FIG. 5 illustrates another embodiment of a bed sheet 500 having handles 104. Bed sheet 500 can be configured similar to any of the above-described bed sheets except that handles 104 are secured to top portion 101 at an angle. In other words, when bed sheet 500 is placed on a mattress, handles 104 would be oriented at an angle to the horizontal orientation of top portion 101, as is shown. Orienting handles 104 at an angle can be preferred in embodiments where the height of sidewall 102 is reduced. For example, in some instances a typical hospital mattress has a thickness of approximately 12 inches. A preferred length for the loop portion of handles 104 may be approximately 9 inches, although any other suitable size may be used. Therefore, the loop portion of handles 104 would be fully contained or concealed underneath sidewall 102 in a bed sheet that is configured for a 12 inch mattress. In contrast, if the mattress is less than 9 inches thick, a portion of handles 104 may extend out from sidewall 102. This could result in a handle 104 being caught on a structure during movement of a hospital bed. By angling handles 104, however, the length of the loop portion of handle 104 may be at least as long as the height of sidewall 102 while still retaining the entire handle underneath the sidewall. In particular, because handles 104 may be formed of a somewhat rigid material, the loop portion of handles 104 may remain angled at substantially the same angle as the top portion of handles 104. In other words, the angle at which handles 104 are secured to top portion 101 may prevent the loop portion of handles 104 from hanging straight downward thereby preventing the handles from being exposed outside of sidewall 102.

(56) In some embodiments, such as is shown in FIG. 5A, an inside surface of sidewall 102 may include a securing structure 501 to which the loop portion of handle 104 may be secured to further prevent the handle from being exposed outside of sidewall 102. For example, securing structure 501 may comprise a button configuration, a hook and look configuration, a pocket configuration, or any other suitable structure that would secure the loop portion of handle 104 at an angle.

(57) In summary, a bed sheet may include handles that are secured to the top portion of the bed sheet using a webbing. By including a webbing in the structure, the bed sheet can have sufficient strength to allow even heavy patients to be lifted using the bed sheet. Further, the use of loop-shaped handles can allow medical personnel to lift a patient more safely and securely with reduced risk of injury.

(58) Many hospitals and health care facilities have zero-lift programs that prohibit health care workers from manually lifting and transferring patients, in order to reduce injuries. FIG. 6A illustrates an example lift system 600 that allows patients to be transported from a bed to another location, without manual lifting.

(59) As illustrated in FIG. 6A, in some embodiments, the lift system 600 may include a bed sheet 602 having handles 104. In some embodiments, the bed sheet 602 may correspond to the bed sheet 100 of FIG. 1, the bed sheet 200 of FIG. 2, the bed sheet 300 of FIG. 3, the bed sheet 400 of FIG. 4, the bed sheet 500 of FIG. 5, or the bed sheet 700 of FIG. 7. Multiple handles 104 may be positioned on lengthwise edges 604 of the top portion 101 of the bed sheet 102. For example, as illustrated in FIG. 6A, three handles 104 may be positioned on a first lengthwise edge 604 and three handles may be positioned on a second lengthwise edge 604. As illustrated in FIG. 6, in some embodiments, the handles 104 may be positioned proximate one or more corners of the top portion 101 of the bed sheet 602. A number and arrangement of the handles 104 along the lengthwise edges 604 of the bed sheet 602 may vary.

(60) In some embodiments, the lift system 100 may include a hoist configured to raise and lower the bed sheet 602. The hoist may include one or more support straps 608 and/or one or more winches 610. In some embodiments, the support straps 608 may extend downwardly from the one or more winches 610 and may be coupled to the handles 104 of the bed sheet 602. In some embodiments, the support straps 608 may be coupled with the handles 104 by fitting, snapping, threading, connecting, attaching, fastening, clipping, hooking, or any other suitable means of coupling. For example, an end of a particular support strap 608 may include a hook, which may be inserted into a particular handle 104. As another example, the ends of the support straps 608 may include loop portions, which may be coupled with the loop portion of the handles 104 using a carabiner or similar device, as illustrated in FIG. 6A. In some embodiments, the sidewalls 102 may be lifted up away from the sides of the bed and folded back in order to access the handles 104, as illustrated in FIG. 6A.

(61) As illustrated in FIG. 6B, in some embodiments, the lift device 600 may include one or more tension rods 612 that may be parallel to the lengthwise edges 604 of the top portion 101 of the bed sheet 602 (referred to herein as lengthwise tension rods 612). The lengthwise tension rods 612 may increase rigidity and stability along a length 615 of the top portion 101, which may prevent the bed sheet 602 from or folding lengthwise or forming a taco shape such that that encloses the patient when a patient is transported using the lift system 600.

(62) In some embodiments, the lengthwise tension rods 612 may be coupled with the handles 104 by fitting, snapping, threading, connecting, attaching, fastening, clipping, hooking, or any other suitable means of coupling. For example, the lengthwise tension rods 612 may extend through the handles 104. Additionally or alternatively, the lengthwise tension rods 612 may include one or more clips 614 or similar devices configured to clip the handles 104 to the lengthwise tension rods 612, which may prevent the tension rod 612 from sliding within the handles 104. In some embodiments, the support straps 608 may be coupled with the bed sheet 602 via the clips 614 of the lengthwise tension rods 612 in addition to, or instead of, being coupled directly to the handles 104. In some embodiments, the handles 104 may include clips (not shown) or similar devices configured to couple the handles 104 with the support straps 608 and/or the lengthwise tension rods 612.

(63) In some embodiments, a particular lengthwise tension rod 612 may extend through multiple handles 104 positioned on the lengthwise edge 604. In some embodiments, a first lengthwise tension rod 612 may extend through the handles 104 positioned on a first lengthwise edge 604, and a second lengthwise tension rod 612 may extend through the handles 104 positioned on a second lengthwise edge 604. In some embodiments, the first lengthwise tension rod 612 may be parallel to the second lengthwise tension rod 612.

(64) In some embodiments, a length of a particular lengthwise tension rod 612 may be approximately equal to the length 615 of the top portion 101 of the bed sheet 602. In some embodiments, the length of the particular lengthwise tension rod 612 may be less than the length 615 of the top portion 101 of the bed sheet 602.

(65) As illustrated in FIG. 6C, in some embodiments, the lift device may include one or more tension rods 616 that may be perpendicular to the lengthwise edges of the top portion of the bed sheet (referred to herein as widthwise tension rods 616). In some embodiments, the widthwise tension rods 616 may extend along at least a portion of a width 618 of the top portion 101. In some embodiments, the widthwise tension rods 616 may be approximately equal to the width 618 of the top portion 101.
