## Title
Physical Therapy Cover

## Abstract

The present disclosure is directed to a physical therapy pillow cover including: a cover made of antimicrobial water resistant fabric, one or more seams, an opening, and a loop strap.

## Background
BACKGROUND OF THE INVENTION
A physical therapy clinic is a fast-paced and physically demanding environment. There are competing pressures to see ever more patients, while providing superior physical care, in a clean environment, while limiting the amount of trash and/or use of environmentally harmful cleaning agents.
Thus, the interests of patient comfort, patient safety and treatment compete with the realities of an increased number of patients per therapist, and the consequent increased number of disposable sheets, pillows, or other medical supplies have created both stresses on patient comfort and cost to the clinic. Moreover, even if disposable materials are not used, the cleaning requirements needed to maintain a safe and clean environment for the significant number of patients leads to an extensive use of laundering using large amounts of water and detergents.
Finally, due to the physical demands unique to the physical therapy clinic, any supplies used therein need to be easily storable and retrievable, quickly cleanable, resistant to physical stresses, and enhance patient comfort during manipulations of the patient during treatment.
The present covers provide a specific solution to address the particular needs of the physical therapy environment.

DETAILED DESCRIPTION OF THE INVENTION 
The present disclosure is directed to a cover for a physical therapy pillow or support which is made of antimicrobial water resistant fabric, and has an opening, and a loop strap.
The pillow used inside the cover can be a conventional pillow such as one used for head support on a bed, having any conventional filling, including down, polyfill, polyester, beans, buckwheat hulls, latex, foam, gel etc. The pillow may be very compressible or only somewhat compressible depending on the use it is applied to.
Pillows in physical therapy are used as supports and as active devices in the treatment of patients. For instance, a pillow can help maintain the conformation of an injured limb or body part while the limb is being treated by physical manipulation from the therapist, or during other types of treatment such as ultrasound, electrostimulation, ice or heat treatment, or infra-red treatment. The pillow in physical therapy may also actively be used as part of the treatment as a cushion between the therapist and the patient, as the therapist applies body weight to adjust the patient's injured body part (such as shoulders, backs, hips, legs etc.).
The pillow when not in active use should be storable. In one embodiment the cover is storable by hanging. In aspect of this embodiment, the pillow cover includes a strap or loop on its interior or exterior surface which allows it to hang from a hook or peg. If the strap is attached to the exterior surface it may be attached to any portion of the pillow cover, including a “flat” surface side of the cover, at a seam of the pillow cover, at a corner of the pillow cover, or attached to the closure mechanism of the pillow cover. If the strap is attached to the interior surface, the strap may be attached to the “flat” surface side of the cover, a seam of the cover, or the closure mechanism. It would be expected that the strap extend through the opening of the cover to the outside, such that the pillow and cover may be hung without turning the cover inside-out. The strap material is not limited and may be made of fabric, rope, polyester, leather, nylon, hemp, or cotton. The strap may be adhered to the pillow cover by any conventional means, such as glue, stitching, snap, or buckle. In one embodiment the strap is an extension of the pillow cover fabric shaped into a strap form.
The location and size of the strap or loop may be determined based on its use. In one embodiment, the strap or loop is at least 2, at least 3, at least 4, at least 5, at least six, at least 7, at least 8, at least 9, at least 10, at least 11, at least 12, at least 13, at least 14, at least 15, at least 16, at least 17, at least 18, at least 19, at least 20, at least 21, at least 22, at least 23, at least 24, at least 25, at least 26, at least 27, at least 28, at least 29, at least 30, at least 35, or at least 40 inches in length.
In one embodiment, there may be multiple straps or loops. In one embodiment, the multiple straps are oriented at opposite sides of the cover such that the pillow cover may be adhered to a surface or table. In an aspect of this embodiment, the straps may be tied around a surface or table to prevent movement of the pillow and cover during physical therapy manipulations or exercises. In another aspect, the multiple straps may be tied together around an object.
In a further embodiment, the strap is structured so that it ends in a loop and thus is a combined strap and loop. The loop may have further attachment devices attached to it, such as carabiners, snaps, etc.
In one embodiment, the strap or loop is able to be opened, such that it becomes a linear strap when opened, and a loop when closed. In an aspect of this embodiment, the strap/loop may include a closure mechanism, such as Velcro, snaps, hooks, male/female plastic connectors, slide release or cam buckles, rings, slides etc.
In one embodiment, the cover is reversible. That is, the inside and outside surfaces of the cover may both be used in the physical therapy context. In one embodiment, the interior and exterior surface of the cover are substantially identical. By substantially identical it is meant that the surfaces of the fabric have similar qualities in their resistance to water, texture of the surface, or “feel.” The seams may or may not be similar, and in one embodiment of the reversible cover, the seams are encased in fabric.
In one embodiment, the pillow is storable by stacking, and incorporates a textured surface which prevents sliding when stacked against other pillows, paper, sheets, towels, tables or other structures. The textured surface may be an additional coating on the outside of the pillow cover, an additional layer, or may be a feature of the fabric of the pillow cover. The textured surface may cover the entirety of the pillow, one side of the pillow (so that the patient's head contacts the untextured surface), or one portion of one or more sides of the pillow. The textured surface may be a non-slip treatment, rubberized, latex, plasticized, PVC treated or coated, vinyl treated or coated, or neoprene coated. The texturing may be in a regular pattern, a decorative pattern, or a logo, covering an adequate surface to prevent slippage of the pillow cover against an exterior surface. The textured surface may be an intrinsic property of the material of the pillow cover, sprayed on, printed on, sewn on, laminated, glued, or otherwise adhered to the pillow cover.
The pillows within the scope of the present embodiments are durable. The pillow covers in particular have a high tensile strength, high tear resistance, and resistant to physical stresses, such as shear, wear, or fraying. In one embodiment the fabric is water resistant. In one embodiment the fabric is antimicrobial or antibacterial. In addition, the fabric may be anti-static. In one embodiment, the fabric is one or more layers of vinyl, polyurethane, PVC-coated polyester, polyurethane backed with a polyester/cotton blend, silicone elastomer-coated fabrics, fluoropolymer-coated fabrics, CRYPTON®-treated fabrics, or silver ion coated or embedded fabrics. A fabric may be “backed” with a second fabric material or fibers. In one aspect the backing is adhered to the exterior fabric by glue or adhesive, stitched to the interior surface of the pillow cover at the seams, quilted, or interwoven with the exterior fabric.
In one embodiment the fabric is free of environmental contaminants. In one embodiment, the fabric is PVC free. In one embodiment, the fabric is a natural fabric which may or may not be treated for water resistance.
The shape of the pillow cover is not particularly limited. For instance it may be square, rectangular, horse-shoe shaped, cylindrical, pyramidal, triangular, or even spherical. The shape will be determined by the use to which it is put. For instance, if the pillow is intended to support the head and neck when the patient is on his or her back, then it may be roughly rectangular (as in a bed pillow), cylindrical (to support the neck), the shape of a European-style pillow (roughly square with an approximately flat upper and lower surface), suspension bridge shaped (e.g. two high peaks with a parabola shaped indentation between the two peaks, for stabilization of the neck or other body part). In an example where the patient is receiving therapy while face-down, the pillow and corresponding pillow cover may be horse shoe shaped to contact the forehead, temples and cheeks of the patient.
The size of the pillow cover is also not particularly limited and may either closely or loosely follow the contours of the pillow. For instance if the pillow is a standard 20×26′′ pillow then the pillow cover may be 21′′×32′′ (pillow sizes are typically standard: 20×26′′; queen: 20′′×30′′; king: 20′′×6′′; European Square: 26′′×26′′ etc.) Thus, there is about an inch of space for each seam. In one embodiment the cover is sized to be at least about one inch longer than each dimension of the pillow, at least about 1.5′′ longer than each dimension of the pillow, at least about 2′′ longer than a dimension of the pillow; at least about 2.5′′ longer than a dimension of the pillow; at least 3′′ longer than a dimension of the pillow; at least 3.5′′ longer than a dimension of the pillow; at least 4′′ longer than a dimension of the pillow; at least 4.5′′ longer than a dimension of the pillow; at least 5′′ longer than a dimension of the pillow; at least 5.5′′ longer than a dimension of the pillow; at least 6′′ longer than a dimension of the pillow; at least 6.5′′ longer than a dimension of the pillow; at least 7′′ longer than a dimension of the pillow; at least 7.5′′ longer than a dimension of the pillow; or at least 8′′ longer than a dimension of the pillow.
There may be more space given in the cover size to one particular dimension as opposed to another dimension of the pillow.
The pillow cover may be open at one or more seams, have a closure or may fully and permanently enclose the pillow. In one embodiment, the cover is open at one seam, permitting the replacement of the pillow. In another embodiment, the pillow cover has one or more closures. The type of closure is not particularly limited, and may be a zipper, Velcro, “zip lock,” snaps, hooks, buckles, or laces etc. The closure may cover the entire seam or may allow openings. If fully covering the entire seam, it should allow passage of air between the interior of the cover to the exterior and vice versa, as air will need to escape if the pillow is compressed. The closure may be hidden by a flap of fabric of the cover or apparent. It is preferred that the closure not be in contact with the patient when the pillow cover and pillow is in use.
The invention will now be described in non-limiting examples, which the skilled artisan will notice may be varied.
EXAMPLES
1. Physical Therapy Loop Pillow Cover
In one embodiment, the pillow cover is made of a backed fabric, where the fabric is a PVC free vinyl, and the fabric is backed with a polyester grid. In one corner a woven polyester strap having a one inch width and a 10 inch length (encompassing the whole of the loop) is sewn into the seam. The pillow cover is 22×36′′. The closure is a zipper attached to the short side of the cover and covered by a flap of fabric. The pillow and pillow cover are used to support a patient's head or limb. The pillow is cleaned after every use by a patient with a anti-microbial cleanser. The pillow cover is resistant to blood, mucous, sweat, tears, or other bodily fluids. The pillow cover after 30 plus cleanings does not show wear.
2. Physical Therapy Manipulation Pillow Cover
In another embodiment, the pillow is 9′′×13′′ and roughly rectangular in shape. A short (3′′) nylon strap is stitched to the center of the flat side of the pillow cover (e.g., the top). A second loop is threaded through the first loop and is about 12 inches in length, such that it easily fits over the wrist/lower arm of the therapist or patient. The second loop is a stabilizing loop used to position the pillow between the physical therapist and the patient for “hands on” manipulations to adjust the back and shoulders of the patient. The therapist places the pillow either on his arm or the arm of the patient. The patient lays on their back and crosses their arms over their chest with the pillow being placed between the patient and the therapist. The therapist then leans over the patient's torso, and applies force to the patient's arms and/or shoulders. The pillow cover protects both the therapist and the patient from bruising. The pillow cover may be stored by hanging on a hook, and cleaned for use with subsequent patients.
