Abstract
A mattress cover for use with air inflated mattresses that includes an integral hand check tunnel formed as part of the cover. The cover includes a top, a bottom, and sides extending between the top and bottom. Openings are formed along the longitudinal sides of the cover and permit access to an enclosed tunnel that extends between the sides of the mattress cover. Flaps are attached to the sides of the mattress cover over the openings along with devices for selectively opening and closing the openings. A caregiver can verify proper inflation of an air mattress placed within the cover by opening the flaps and extending a hand into the tunnel. The cover can be used with a single air inflated air mattress with the tunnel overlying the mattress, in a dual configuration where one air mattress is placed over the other with the tunnel being placed between the mattresses, or with an air mattress placed upon a foam base with the tunnel being placed between the mattress and foam base.
Description




The present invention relates to mattress covers generally, and more particularly to mattress covers for air inflated mattresses for therapeutic uses.




BACKGROUND OF THE INVENTION




Patients that are bedridden for appreciable periods of time often develop persistent and painful bedsores. The relatively inactive bedridden patients in hospitals, nursing homes, and home care have a high incidence of decubitus ulcers or bedsores. It is generally recognized that this phenomenon is caused by the relatively high pressures experienced at crucial points on the patient's body where body weight is concentrated but the thickness of the flesh between the skeletal structure and the supporting surface is minimum.




SUMMARY OF THE INVENTION




The present invention is directed toward a new mattress cover for air inflated mattresses for therapeutic uses, having an integral hand check tunnel to allow a caregiver to verify proper patient support of an air inflated mattress within the mattress cover. The hand check tunnel allows such verifications with minimal disruption to the patient and without the caregiver coming into contact with patient contaminates and excrements.




The invention will be used when a single air inflated mattress is placed within a mattress cover, in a dual configuration where one air inflated mattress is placed on top of another and then both placed within a mattress cover, or where an air inflated mattress is placed on top of a foam base and then both are placed within a mattress cover. In a mattress system using a single air inflated mattress, the air mattress is placed on top of the hand check tunnel of the present invention. In a mattress system using dual air inflated mattresses, the hand check tunnel of the present invention is placed between the two mattresses. In a mattress system using a single air inflated mattress with a foam base, the hand check tunnel of the present invention is placed between the mattress and the foam base.




One preferred embodiment of the present invention is a hand check tunnelled mattress cover comprising, a mattress cover for air inflated mattresses for therapeutic use, having a top, a bottom, and sides therebetween defining the cover, including its width and length dimensions; corresponding openings in the opposing sides of the cover midway along its length dimension; an enclosed tunnel within and independent of the top and bottom of the cover connecting the openings in the opposing sides of the cover; and flaps attached to the cover above the openings with devices for selectively opening and closing the openings.




A principal object of the present invention is to allow a caregiver to verify proper inflation of an air inflated patient mattress (support) with minimal disruption to patient.




It is a further object of the present invention to minimize contamination within an air inflatable mattress cover by providing an isolated passage to verify proper support between materials.




It is a further object of the present invention to minimize contamination within container, yet still allow a hand check to be performed without opening of the mattress cover.




It is a further object of the present invention to provide an area to install a heating or cooling device (fluid as medium) to adjust body temperature.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




A 200 Denier Oxford Nylon 4.6 oz. polyurethane coated fabric with ABFR additives is the preferred fabric used to date to construct the hand check tunnelled mattress cover


10


of the present invention. This preferred fabric is also low vapor permeable (LVP) and moisture impermeable, which releases heat generated by the body. The LVP fabric keeps moisture from entering the mattress cover, thus eliminating a breeding ground for living organism and eliminating bioaerosols. The hand check tunnel


12


of mattress cover


10


provides a means to check for proper inflation of air inflated matresses placed within the cover, thereby eliminating the need for a caregiver to come into direct contact with any patient contaminates and excrements on the cover


10


. The hand check tunnel


12


also eliminates any possible contamination within the mattress cover


10


, thus reducing or eliminating bioaerosols.




To form the hand check tunnel


12


, the preferred fabric is cut into a long rectangular form, folded in half lengthwise, and then sewn together along the open lengthwise side, resulting in a tunnel configuration. This is then turned inside out. The fabric is then attached at the open ends


14


,


16


of the hand check tunnel


12


by conventional sewing techniques, to a conventionally formed mattress cover


18


. Both open ends


14


,


16


of hand check tunnel


12


are attached along their top


20


, sides


22


, and bottom


24


to the sides of the mattress cover


18


, where a rectangular opening has been cut in the cover corresponding to the dimensions of open ends


14


,


16


of the hand check tunnel


12


. The hand check tunnel


12


is orientated centered and perpendicular to the length of the mattress cover


18


. The openings at both ends


14


,


16


of hand check tunnel


12


are coverable with fabric flaps


26


,


28


, which have been fabricated like pillow covers. These fabric flaps


26


,


28


are sewn to the outside of the mattress cover


18


, above the tunnel openings


20


. The fabric flaps


26


,


28


are removably securable to the sides


30


,


32


of the cover


18


by means of a hook material


34


on both sides of the openings


14


,


16


and a loop material


36


on the backside of the corresponding side edges of the tunnel flaps


26


,


28


. The open ends


14


,


16


of hand check tunnel


12


may then be covered with flaps


26


,


28


to close the hand check tunnel openings


14


,


16


.




The hand check tunnel


12


is used to verify proper inflation for proper support of a patient, by a caregiver, of a single air inflated mattress


38


placed within mattress cover


18


(FIG.


2


). The hand check tunnel


12


may also be used to verify proper inflation for proper patient support when placed between two air inflated mattresses


38


,


40


(FIG.


3


). The hand check tunnel


12


may also be used to verify proper inflation when placed between a foam base


42


and a single air inflated mattress


38


(FIG.


4


).




A patient caregiver opens one of the flaps


26


,


28


of hand check tunnel


12


and inserts either their right or left hand, palm up, into one of the open ends


14


,


16


of hand check tunnel


12


. The caregiver inserts their hand into the hand check tunnel


12


until their hand is under the patient's buttocks. This operation is performed in this way to verify proper inflation of the air inflated mattress beneath and supporting the patient for proper support of the patient. In this regard, note that the views of

FIGS. 1-4

are bottom views. Once the bottom of the mattress cover


44


is closed and zipped shut, using typical zipper


46


, the entire mattress cover


10


of

FIGS. 1-4

is inverted top to bottom from the orientation shown in

FIGS. 1-4

before a patient is placed on the top surface of the cover


18


. It can then be appreciated that the hand check tunnel


12


will always have a single air inflated mattress


38


between a patient and the hand check tunnel


12


.
