The invention relates generally to bed linens and more specifically to a linen system constructed from a single piece of material for safety and comfort of the user.
Every year more than 1500 suicides take place at inpatient hospital units throughout the United States, and of that number, more than 70% of self-harm attempts are as a result of asphyxiation by hanging. Over 50% of the time the five primary items utilized for such attempts are mattress covers, sheets, pillow cases, pillows and blankets. The reasons are obvious: they are easily accessible and they are easy to manipulate. Typical bed sheets and bedding can be torn or wrapped tightly, increasing the likelihood that a suicide attempt will be lethal. The Federal National Center for Patient Safety reports that ligatures made from sheets or bedding were used in over 50% of all hanging suicides at inpatient psychiatric units.
Practical application of a linen system must not only be safe for the particular concern addressed herein but must be practical and functional for the individuals involved. With regard to a patient who suffers from self-harming or suicidal behavior and thoughts, the primary concern is to avoid opportunity for which a self-harm device may be formed from a bed sheet, blanket and/or bed linen. The comfort and care of the patient is another concern where use of a safety linen system must require minimum effort in linen changes for patients who have difficulty with movement and/or are impaired. With regard to the caregiver and institution who manage the patient and the facility environment, the safety linen system should minimize expenses and effort by a caregiver for linen changes while maximizing benefit and ease of use to the caregiver and patient.
Previous attempts to address the problem have resulted in bed linen systems having at least one blanket portion and at least one mattress cover that may be difficult to remove from the mattress and/or are made of sufficiently thick materials that reduce the ability to form a self-harm device. In these previous attempts at addressing the problem, care has been taken when attaching the blanket portion to the mattress cover in an attempt to prevent a patient who suffers from self-harming or suicidal behavior and/or thoughts from disassembling the system. For example, multiple runs of stitching, hard plastic rivets, welds, adhesives, etc., have all been suggested as being used to securely attach the blanket to the mattress cover to form a union. However, the disadvantages associated with all of these known linen systems is that there exists a union or attachment point between the two separate units forming the blanket and mattress cover. As such, a determined patient who suffers from self-harming or suicidal behavior and/or thoughts is likely to focus his or her attention at the union in order to separate the units to form a self-harm device. Additionally, because a union or attachment point exists in each of these known bed linen systems, continued application of force (i.e., through regular use, washing, and/or attempted separation) will eventually cause the union to fail since the stitching perforates the material and creates a weak point.
Further attempts have been made to locate the union or attachment point at various locations, such as at the top or bottom edges of the mattress cover or beneath the mattress, to minimize the ability to separate the blanket from the mattress cover by a determined patient. However, application of enough force to the blanket (e.g., by pulling) will eventually cause the union to fail and/or may cause the mattress to bend or bow upward allowing the linen to release from the mattress. Likewise, attempts to prevent previous linen systems from being pulled away from the mattress have included providing portions of the bedsheet cover to be folded under the mattress. While such pockets enveloping substantial portions of the mattress may inhibit removal by the patient, the amount of effort required by a caregiver to replace the linens for cleanliness is unreasonably large. Further, continuous removal/replacement of such linens by caregivers causes excess stress and premature failure at stitched or bonded unions of various materials.
Therefore, there is a need to provide a true one-piece bed linen solution that is an attractive and safe alternative to the standard bed linens and sheets used in hospitals and institutions, and eliminates the need for an attachment point or union between the blanket and mattress cover, where the linen is not easily removed from a mattress by a patient, yet allows for easy removal by a caregiver for washing/changing. The present invention accomplishes these objectives.
The invention provides a bed linen system. The bed linen system includes a one-piece panel having a top side, a bottom side, and an axis. The one-piece panel includes a bed sheet portion configured to fit on a mattress, a pair of opposing slits, each of the slits extending from a side edge of the panel toward the axis, wherein the slits form a location where the panel is folded over itself when placed on the mattress, a plurality of gussets, each gusset being formed by folding at a bottom edge of the bed sheet portion of the panel and securely attaching a side to an adjacent edge of the bed sheet portion, wherein each gusset is configured to allow the bed sheet portion to envelop a corner of the mattress, and a blanket portion configured to cover the bed sheet portion and drape over side edges of the mattress when the panel is folded over itself. Thus, the slits are configured to separate the bed sheet portion from the blanket portion and direct tension toward the axis resulting in gripping of the mattress when the blanket portion is pulled in a direction away from the fold. In various embodiments, the slits are also configured to allow a user to fold the blanket portion toward the axis for ventilation during use
In various embodiments, the gussets may be shaped to resemble a parabolic curve comprising a long edge and a short edge, and wherein the long edge is integral to the side edge of the panel and the short edge is securely attached to a headboard-side edge or a footboard-side edge of the bed sheet portion of the panel. In various embodiments, the short edge of each gusset has a length substantially equivalent to that of each slit. The bed linen system may further include a reinforcing strap fixedly attached to a corner of each gusset and extending along a side of the bed sheet portion and terminating at a lower portion of the blanket portion, wherein the reinforcing strap is configured to enhance the tension being directed toward the axis, thereby resulting in increased gripping of the mattress when the blanket portion is pulled in a direction away from the fold. In various embodiments, the bed linen system may also include a reinforcement fixedly attached to a second corner of each gusset, wherein the reinforced corners of each gusset form hinge points configured to facilitate removal of the linen system by a caregiver. In various embodiments, the reinforcing strap may also include a pair of extensions configured for attachment to a top side of the bed sheet portion. In various embodiments, the bed linen system may also include an end cap permanently attached to a footboard-side edge of the bed sheet portion of the panel.
In various embodiments, each of the reinforcing strap and reinforcement are made from a material independently selected from the group consisting of binding tape, gross grain, woven or non-woven material, nylon, cotton, cotton polyester blend, or any combination thereof. In various embodiments, the panel is made of a quilted material, such as a cotton polyester blend. In various embodiments, the bed sheet portion also includes one or more (i.e., 1, 2, 3, 4, 5, or more) flexible inserts disposed in each side and positioned to take up slack resulting from use of the system on an adjustable bed.
In certain embodiments, the bed sheet portion also includes an integrated pillow securely attached to the bottom side of the panel. The pillow includes a top layer, a bottom layer, and an underlayment, wherein the pillow is securely fastened to the panel by one or more stitches selected from the group consisting of bar-tack stitches, single stitches, double stitches, triple stitches, blind stitches, other stitches, and any combination thereof.
In another aspect, the invention provides a bed linen system. The bed linen system includes a one-piece panel having a top side, a bottom side and an axis. The one-piece panel includes a bed sheet portion configured to fit on a mattress, a pillow securely attached to the bottom side of the panel at a location corresponding to a headboard-side of the bed sheet portion, a pair of opposing slits, each of the slits extending from a side edge of the panel toward the axis, wherein the slits form a location where the panel is folded over itself when placed on the mattress, and a blanket portion configured to cover the bed linen portion and drape over side edges of the mattress when the panel is folded over itself. In certain embodiments, the slits are configured to separate the bed sheet portion from the blanket portion and direct tension toward the axis resulting in gripping of the mattress when the blanket portion is pulled in a direction away from the fold.
In certain embodiments, the bed linen system also includes a plurality of gussets, each gusset being securely attached to a corner of the bed sheet portion of the panel, wherein each gusset is configured to allow the bed sheet portion to envelop a corner of the mattress. The gussets may be shaped to resemble a parabolic curve and comprising a long edge and a short edge, and wherein the long edge is securely attached to the side edge of the panel and the short edge is securely attached to a headboard-side edge or a footboard-side edge of the bed sheet portion of the panel. In various embodiments, the short edge of each gusset has a length substantially equivalent to that of each slit. The bed linen system may further include a reinforcing strap fixedly attached to a corner of each gusset and extending along a side of the bed sheet portion and terminating at a lower portion of the blanket portion, and wherein the reinforcing strap is configured to enhance the tension being directed toward the axis, thereby resulting in increased gripping of the mattress when the blanket portion is pulled in a direction away from the fold. In various embodiments, the reinforcing strap also includes a pair of extensions configured for attachment to a top side of the bed sheet portion. In various embodiments, the bed linen system may also include a reinforcement fixedly attached to a second corner of each gusset, wherein the reinforced corners of each gusset form hinge points configured to facilitate removal of the linen system by a caregiver. In various embodiments, the bed linen system may also include an end cap permanently attached to a footboard-side edge of the bed sheet portion of the panel.
In various embodiments, the panel is made of a material having a thickness and strength to prevent tearing and hinder persons from creating a self-harm device. In various embodiments, the panel is made of a quilted material, such as a cotton polyester blend. In various embodiments, the bed sheet portion also includes one or more (i.e., 1, 2, 3, 4, 5, or more) flexible inserts disposed in each side and positioned to take up slack resulting from use of the system on an adjustable bed.
In certain embodiments, the bed sheet portion also includes an integrated pillow securely attached to the bottom side of the panel. The pillow includes a top layer, a bottom layer, and an underlayment, wherein the pillow is securely fastened to the panel by one or more stitches selected from the group consisting of bar-tack stitches, single stitches, double stitches, triple stitches, blind stitches, other stitches, and any combination thereof.
In another aspect, the invention provides a pillow for use with the linen system provided herein. The pillow includes a one-piece panel having a top portion, a bottom portion, and a hinge portion, wherein the top portion and bottom portion are filled with batting and subdivided into a plurality of channels by stitching, and wherein the channels of the top portion are formed perpendicular to the channels of the bottom portion such that when folded at the hinge portion, the hinge portion forms a side of the pillow. In various embodiments, each of the top portion and bottom portion contain 2, 3, or 4 channels. In various embodiments, the pillow includes a pillow case configured to contain the pillow, wherein the pillow case is sewn shut to prevent removal of the pillow therefrom.
The present invention provides a linen system constructed from a single piece of material for safety and comfort of the user. By providing a one-piece design, the system hinders persons from tearing the panel to create a self-harm device, and facilitates housekeeping procedures for institutions housing a plurality of persons.

Based on in-depth research, it has been found that inpatient complaints were consistent in regard to lack of sleep due to bedding. The noise and sweating that is caused by a vinyl mattress with thin sheets creates an environment that is disruptive to the normal sleep pattern. This lack of sleep makes receptiveness to treatment more difficult and can lead to a prolonged need for therapy. The present invention provides a one-piece bedding system formed from thick quilted material that is more difficult to use as a self-harm device. By bulking up the materials, a less lethal alternative to traditional sheets, pillow cases and mattress covers is provided. The use of quilted, thicker materials makes it less likely that a patient attempting to hang himself/herself will be able to generate the kind of pressure required around the carotid artery for asphyxiation. (It only takes four to five minutes of adequate pressure on the carotid artery to produce death by oxygen deprivation to the brain.)
As traditional sheets only provide a thin layer between the patient's body and the vinyl mattress, the result is a high degree of discomfort. By quilting the bottom sheet portion of the bed linen system, the invention provides a sufficient buffer between the patient's body and the mattress that allows for better heat distribution and helps in providing a good night's sleep, which in turn aids in the treatment process and overall well-being of the patient. The custom fitted bed sheet portion creates a snug fit to the mattress, thereby providing bedding that is difficult to remove but, at the same time, is still easy enough for staff to make linen changes.

In various embodiments, the panel 10 is made of a material having a thickness that hinders persons from creating a self-harm device. This bed linen system 100 is configured to eliminate the use of sheets and may therefore be used in place of sheets. Preferably, the panel 10 is made of a quilted material, with the quilting being configured to strengthen the material. In various embodiments, the material is a washable durable material, such as a cotton polyester blend, but other suitable materials with similar properties may be used. A quilted cotton material adds to a person's comfort and the quilted panel 10 may provide aesthetic and therapeutic value. Threads used for the quilting may be heavy polyester threads to make the bed linen system 100 tough and resistant to tearing. In various embodiments, the perimeter of the panel is provided with a plurality of stitching for added safety and comfort. Exemplary forms of stitching include, but are not limited to, bar-tack stitches, single stitches, double stitches, triple stitches, blind stitches, any other suitable types of stitching, and any combination thereof.
Integrated into the bed sheet portion 16 of the panel 10 are a plurality of gussets 30 located at the edges of the bed sheet portion 16. In various embodiments, the gussets 30 may be substantially shaped like a right triangle with the hypotenuse 31 being shaped to resemble a parabolic curve (

Accordingly, use of linen system 100 provides stress-free linen changes by those charged with maintaining bedding of patients. As a result of the gussets 30 being placed under each corner of the mattress 18, while allowing bed sheet portion 16 to drape over the sides of the mattress 18, a hinge H is formed along the hypotenuse of the gusset 30 by which the bedding may be removed with correct application of force, thereby reducing tension and/or stress to the seams of the linen system 100 (
Any of the above-discussed embodiments of the linen system 100 may be made formed from a panel 10 that itself is formed from two separate pieces of similarly-shaped material that are securely fastened to each other around the entire perimeter thereof to form a single piece of material. In various embodiments, the strength of the linen system 100 may be enhanced by inclusion of additional stitching at the bottom edge of the blanket portion 22 at the approximate location where the panel 10 folds over itself. In various embodiments, this corresponding area of panel 10 may be covered with binding tape and fastened using one or more of bar-tack stitches, single stitches, double stitches, triple stitches, blind stitches, and any combination thereof.

As the entire pillow 60 is washable, the pillow does not need a pillowcase, thereby eliminating the possibility of being used to cause self-harm to a patient. However, in certain embodiments, the entire pillow is provided in a pillow case 68, which is sewn shut to prevent removal thereof (
Additionally, as the pillow may be quilted and/or otherwise formed from the same material as that of panel 10, the pillow is difficult to tear open to use for suffocation. Further, the two folded pillow portions with integrated channels 65 and/or stitching 50 create a clumping-resistant stuffing that will stand up to numerous uses and washings while retaining sufficient fluff such that the pillow 60 has a thickness that is substantially equal to the thickness of typical pillows. Thus, pillow 60 may be used in conjunction with linen system 100 in hospitals or institutions that require frequent washings of pillows for infection control.
