Abstract
Abstract A mattress assembly for accommodating a bedpan is described to enable a patient to dispose of his human wastes without leaving his bed. A cavity is formed in the mattress for receiving a slidable insert. The insert is held in the cavity by permanent magnets. The sides of the insert are contoured to form curved ridges that slide in corresponding grooves formed in the walls of the cavity.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
226 words
A mattress assembly to accommodate a bedpan comprising: a single unitary mattress having an upper patient support surface and a parallel bottom surface; an elongated cavity of a prescribed cross section formed in the upper surface extending from the central area of the mattress to one side of the mattress for receiving the bedpan, said cavity having a bottom wall spaced upwardly of the bottom surface and substantially parallel with the top surface of the mattress for supporting the bedpan; said cavity further including two countoured side walls; a first permanent magnet mounted in the bottom wall of the cavity; a mattress insert having a cross section equal to or slightly larger than that of the cavity; said insert being slidably received in the cavity and having top and bottom surfaces and contoured sides for permitting horizontal sliding movement of the mattress insert in the cavity from a closed position totally filling the cavity and an open position to permit the placement of a bedpan in the cavity supported by the bottom wall with an upper rim of the bedpan being substantially flush with the upper surface of the mattress, and a second permanent magnet mounted on the bottom of the mattress insert for attracting the first permanent magnet to hold the mattress insert firmly in place when the mattress insert is in the closed position.

Claim 3
Dependent Claim
54 words
A mattress assembly as defined by claim 1 wherein the contoured side walls of the cavity diverge downwardly from the upper surface of the mattress to the bottom wall of the cavity to receive the complementary contoured sides of the mattress insert to prevent upward movement of the mattress insert relative to the mattress.
Claim 4
Dependent Claim
73 words
A mattress assembly as defined by claim 1 further comprising a mattress sheet having an opening complementary to the cavity; wherein the mattress sheet opening is elongated and extends over the cavity and down the side of the mattress below the mattress insert and wherein the mattress sheet has a plurality of flaps defining the opening that may be folded into the cavity between the cavity walls and the walls of the insert.
Claim 5
Dependent Claim
26 words
A mattress assembly as defined by claim 1 further comprising a case formed of sheet material for receiving the insert and covering the insert top surface.
Claim 6
Dependent Claim
51 words
A mattress assembly as defined by claim 1 wherein an additional cavity and mattress insert are included along the bottom surface of the mattress along a side opposite the one mattress side and that are substantially identical to the cavity and mattress insert provided along the upper surface of the mattress.
