Abstract

A frame of foam polymer with a rectangular cutout, positioned to underlie the major part of the body of a patient recumbent thereon, rests on a baseplate serving as a support for a multiplicity of square or rectangular inserts of like foam material detachably pasted onto the base so as to be removable at locations proximal to a pressure-sensitive part of the patient'"'"''"'"'s body. A transverse pad at the foot end of the mattress has vertical recesses open toward the head end to receive the feet of the patient whose legs rest on anatomically shaped wedge pieces which extend into these recesses but terminate short of their closed ends to leave room for the unsupported heels of the patient.

Claims

1. A mattress comprising a generally rectangular horizontal frame of resilient material provided with a central longitudinal cutout positioned to underlie the major part of the body of a patient recumbent thereon, a multiplicity of resilient inserts closely juxtaposed in said cutout to form a continuous surface with said frame, said inserts being selectively removable from said frame to relieve pressure on a sensitive part of the patient'"'"''"'"'s body, a transverse pad extending entirely across said frame at the foot end thereof, said pad having a pair of vertical recesses open toward and defined in part by a vertical wall facing the head end for receiving the feet of the patient, and two elongate wedge pieces shaped to support the legs of the patient up to the thighs, said wedge pieces rising from said surface and extending into said recesses while being spaced from the respective walls thereof by a distance sufficient to accommodate the unsupported heels of the patient.

2. A mattress as defined in claim 1, further comprising a baseplate underlying said cutout and supporting said inserts.

3. A mattress as defined in claim 2 wherein said inserts are adhesively but detachably secured to said baseplate, said pad is adhesively but detachably secured to said frame and said wedge pieces are adhesively but detachably secured to and overlie said inserts.

4. A mattress as defined in claim 3 wherein said baseplate has an outline substantially registering with that of said frame.

5. A mattress as defined in claim 4 wherein said inserts are provided with pressure-activated adhesive layers on their undersides.

6. A mattress as defined in claim 3 wherein said inserts are rectangular.

7. A mattress as defined in claim 3 wherein said pad, said wedge pieces, said frame and said inserts consist essentially of foam polymer.

8. A mattress as defined in claim 3, further comprising a headrest at the head end of said frame, said cutout terminating substantially at said headrest.
