(a) Field of the Invention
The present invention relates to a cover for a mattress and bed deck. More particularly, the present invention relates to a mattress and bed deck cover for an adjustable bed that reduces the exposure of the mattress and bed deck to unsanitary conditions.
(b) Description of the Prior Art
Mattress covers are commonly used to protect mattresses from staining, soiling, or other results of contact with unsanitary conditions. The need for effective mattress covers is greater in a healthcare setting, where contact with large scale contaminants, such as blood or waste products, and small scale contaminants, such as bacteria or fungi, is a daily occurrence. Mattress covers must be cleaned on a regular basis to maintain a sanitary environment.
Mattresses are supported by bed decks. Bed decks may come into contact with the same unsanitary conditions as mattresses and mattress covers. For example, waste produced by a patient may flow off the mattress or mattress cover and accumulate on the supporting bed deck. Under current techniques, the cumbersome mattress must be manually raised from the bed deck, the bed deck cleaned by hand using a germicidal solution, and the mattress replaced atop the bed deck. However, hospital workers may neglect to clean the bed deck, or may not fully clean the entire surface of the bed deck. Alternatively, a worker may insufficiently clean a mattress then transfer contaminants from the mattress when he moves on to clean the bed deck. Furthermore, manual cleaning may not be sufficient to eliminate bacteria embedded in the bed deck or kill fungal spores. Any contamination on the bed deck may be passed to clean mattress covers or bed sheets, from which the contaminants may contact a patient.
A need exists for a removable cover that protects both mattresses and bed decks from unsanitary conditions and is capable of being laundered. This need is complicated in a healthcare environment, where mattresses and bed decks are incorporated into adjustable beds. Adjustable beds used in healthcare settings include bed decks and mattress which can be raised, lowered, and articulated into various configurations. A need exists for a removable cover for the mattress and bed deck of an adjustable bed that is capable of protecting and remaining attached to the mattress and bed deck while the adjustable bed adopts different configurations.
The aforementioned problems have been solved in the present invention, which provides a mattress and bed deck cover. More particularly, the present invention relates to a mattress and bed deck cover for an adjustable bed that reduces the exposure of the mattress and bed deck to unsanitary conditions.
Conventional bedding utilizes a fitted sheet that encapsulates the top and sides of a mattress, and a flat sheet and one or more blankets that are tucked into the space between the mattress and the supporting bed deck or box spring. One difficulty with using a single cover to protect both the mattress and the bed deck is that access to the space between the mattress and bed deck would be lost and bedding material could not be tucked into that space. The present invention solves this problem by including a channel at the foot end of the cover, whereby a flat sheet and blankets may be tucked between the mattress and bed deck. In some embodiments, the present invention may also include a channel at the head end of the cover, whereby a fitted sheet may be wrapped around both the head end and foot end of the mattress. In some embodiments, the present invention may also include at least one flap extending from the cover and used to cover specific features of the bed deck.
Adjustable beds, as used in hospitals and other healthcare settings, can be raised, lowered, and adjusted into various configurations. The present invention is capable of remaining in position on the mattress and bed deck while the adjustable bed adopts different configurations. While the bed is positioned horizontally, the mattress and bed deck cover fits tautly over the bed. A taut cover eliminates folds and gathers in which waste may accumulate and which may cause pressure ulcers.
Adjustable beds, as used in hospitals and other healthcare settings, may incorporate devices, controls, and fittings such as, for example, controls to raise or lower parts of the bed or fittings for I.V. poles to be removably attached to the bed. Access to these devices, controls, and fittings cannot be restricted by the mattress and bed deck cover. The present inventions solves this problem by providing a sufficient number of apertures to grant access to devices incorporated into the bed deck, while still protecting the bed deck from contamination and remaining securely attached to the mattress and bed deck. Apertures may also be included to allow the mattress and bed deck cover to fit around bed rails, handles, other structural features of adjustable beds.
Certain inorganic agents, such as metal ions, are known to have antimicrobial and antifungal activity. Silver is known as a broad spectrum antibiotic with minimal health concerns. Copper is known to have antifungal activity and a synergistic effect with silver against bacteria. Zinc has weak antimicrobial activity and the ability to moderate the release of silver from a carrier. While there is a low frequency of bacteria developing resistance to silver, exposure to sub-lethal concentrations of silver may increase the chance of resistance development.
The present invention combines the antimicrobial and antifungal properties of metal ions with the need for more hygienic surfaces in bedding. In this embodiment, the present invention relates to the incorporation of metal ions into a film coating applied to a mattress and bed deck cover. More particularly, the present invention relates to a mattress and bed deck cover coated with a film coating material incorporating soluble glass carriers containing silver. A particular advantage of this embodiment of the present invention over surface treatment of bedding material with antimicrobial agents is that metal ions are not released into the environment, but kill by directly contacting the microbes or fungi. By providing a substantially nonleaching film coating, metal ions are not released into the environment, reducing the risk of bacteria developing resistance due to exposure of sub-lethal concentrations of metal ions. Thus the present invention provides the antimicrobial effectiveness of metal ions while minimizing the chances of creating bacterial strains resistant to the antimicrobial activity of metal ions. Another particular advantage of this embodiment is that incorporation of antimicrobial and antifungal properties into the present invention reduces odors.
The mattress and bed deck cover is designed to be laundered using U.S. Center for Disease Control-approved healthcare laundering techniques, e.g., washing with detergent in water at a temperature greater or equal to 160° F. (71° C.) for at least 25 minutes. Quality conventional mattress covers for hospital use are manufactured using fabric welds to prevent fluids from wicking through the cover to the mattress. However, standard fabric welds tend to break during repeated laundering cycles. In addition, standard healthcare laundering techniques may not be sufficiently intense to eliminate bacteria embedded in a conventional mattress cover. In the present invention high strength welds are used which are capable of withstanding the agitation and high temperature of the laundering process. Furthermore, the antimicrobial film coating of the cover kills bacteria and prevents them from becoming embedded in the cover. Therefore, a standard healthcare laundering process is sufficiently intense to decontaminate the present invention, whereas it may not be sufficient to decontaminate a cover without such a film coating.
In one embodiment, the present invention is a mattress and bed deck cover comprising a top surface, a head end descending from the top surface, a foot end descending from the top surface and opposing the head end, a pair of opposing sides descending from the top surface and substantially perpendicular to the head end and the foot end and connected thereto, means for removably fixing the cover in relation to a mattress and a bed deck, and a foot end channel extending the width of the foot end and a portion of the length of the sides, wherein the cover is sized to enclose the mattress and at least a portion of the bed deck, with the foot end channel oriented to interpose a portion of the mattress and the bed deck.
