Definitions

  • 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 patients 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 tenninate short of their closed ends to leave room for the unsupported heels of the patient.
  • the general object of my present invention to provide a mattress construction which can be quickly and easily adapted to specific requirements for the purpose of relieving local pressure on the body of a patient.
  • a related object is to provide means in combination with such a mattress for keeping the feet of the patient free from pressure of both the underlying mattress and an overlying blanket.
  • a further object is to provide a mattress, e.g., for hospital beds, which can be quickly restored to use by a replacement of certain parts upon being soiled or otherwise damaged.
  • I provide a mat tress in the form of a generally rectangular horizontal frame, commensurate with the body measurements of a patient whom it is intended to support, which has a central longitudinal cutout positioned to underlie the major part of the patients body in a recumbent position, this cutout being filled by a multiplicity of preferably rectangular (e.g., square) inserts closely juxtaposed therein to form a continuous surface with the frame.
  • Both the frame and the inserts are made of resilient cushioning material, preferably a foam polymer, as is a headrest carried by the mattress.
  • the inserts are individually and selectively removable from the frame to relieve the pressure upon sensitive parts of the patients body.
  • the frame and the inserts are supported on a baseplate which underlies the cutout and may have an outline substantially registering with that of the frame.
  • the inserts may be detachably pasted onto that baseplate, as with the aid of a pressure-activated adhesive.
  • the foot end of the mattress frame carries a transverse pad formed with a pair of vertical recesses which are open toward the head end to receive the feet of the patient.
  • a blanket covering the lower body of the patient can then be draped over this pad so as to stay clear of his toes for the avoidance of possible discomfort.
  • the pad may be made of the same polymeric foam material as the rest of the mattress structure.
  • FIGS. 2, 4 and 6 are plan views of three different embodiments of my invention.
  • FIGS. 1, 3 and are cross-sectional views taken on lines I- l, lllIII and V-V of FIGS. 2, 4 and 6, respectively.
  • the mattress shown in FIGS. 1 and 2 comprises a rectangular frame 2 of foam plastic resting on a rigid baseplate l coextensive therewith.
  • Frame 2 has a rectangular central cutout 7, occupied by an array of substantially identical inserts 3 of like foam plastic and square outline.
  • the inserts 3 are detachable cemented onto the baseplate l by a pressure-activated adhe' sive which also serves to hold the frame 2 in position.
  • a headrest 4, also of foam plastic, is similarly cemented onto the right-hand end of frame 2 just beyond the cutout 7.
  • FIGS. 5 and 6 show a mattress similar to that of FIGS. I and 2 with the addition of a pad 5, likewise of foam plastic, detachably cemented onto the frame 2 just beyond the end of cutout 7.
  • a part of the frame 2 and some of the inserts 3 are overlain by two pieces wedge pieces 6 which are anatomically shaped to conform to the hollow of the knees of the patient and to support his shanks down to the region of the ankles.
  • Two forwardly open vertical recesses 5a in pad 5 receive the ends of the wedge pieces 6 with enough clearance to accommodate the heels of the patient whose toes do not quite reach the top of the pad so that they will not be contacted by an overhanging blanket 8.
  • the wedge pieces 6 may be strips of foam plastic also detachably cemented to the underlying mattress portions.
  • 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 pa tients 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.
  • a mattress as defined in claim I further comprising a baseplate underlying said cutout and supporting said inserts.
  • said pad, said wedge pieces, said frame and said inserts consist essentially of foam polymer.
