Definitions

  • This invention relates to a foam mattress intended particularly for orthopaedic use.
  • a known mattress has springs of differing spring rates in different areas of the mattress but this mattress does not exhibit the re ⁇ quired differential resilience along its length and width. It. is also known to introduce sections of board inside the middle of a mattress to increase the hardness in a selected area, but this, has similar disadvantages. Neither construction allows the resilience to be adjusted according to the particular requirements of each individual patient.
  • Foam has commonly been used as a material for both non-orthopaedic and orthopaedic mattresses. It
  • a mattress comprising an internal body of plastics foam material and a flexible cover surrounding the body, wherein the body includes a plurality of foam sections of at least two different hardnesses, the cover being removable to allow foam sections to be replaced thereby to alter the hardness characteristics of the mattress.
  • the foam sections are cuboid or cubic blocks of different hardnesses which are arranged on a foam base layer to produce a rectangular mattress interior with the required distribution of relatively hard and relatively soft areas.
  • the blocks are interchangeable so that the arrangement can be altered to suit various different patients.
  • the cover fits closely around the internal foam body to hold the blocks in abutting relationship.
  • FIG. 1 is a perspective view of a first mattress in accordance with the invention with a portion of the cover cut away to show the interior;
  • Figs. 2a and 2b are diagrammatic plan views of the interior of the mattress for two different patient conditions
  • Fig. 2c is a key to the symbols used in Figs. 2a and 2b;
  • Fig. 3 is a diagrammatic plan view of a mattress interior comprising elongate foam blocks
  • Fig. 4 is a cut-away perspective view of an alternative mattress interior
  • Fig. 5 is a cut-away perspective view of a furthe alternative mattress interior.
  • a first embodiment of mattress in accordance with the invention has an internal body of foam material comprising a plurality of foam blocks 1 laid on a soft foam base layer 2.
  • the blocks are approximately 150 mm square by 120 mm thick, and are made of fire retardant polyether foam with a maximum closed cell and minimum open cell arrangement.
  • the blocks are of'different hardnesses and may be colour coded for easy identification. Hardness of the foam blocks may be expressed in terms of an indentation hardness index as specified for example in British Standard No. BS4443
  • polyether foam being available in different hardnesses with indexes in the range 20N to 180N.
  • foam blocks in the range 50N to 180N a used in a variety of arrangements depending on the patient condition. If firmer blocks are required, re ⁇ constituted foam having a hardness index of 340N to 380N may be used.
  • the base layer 2 is approximately 25 mm thick and extends over the whole area of the mattress.
  • a similar upper sof foam layer (not shown) may be placed over the blocks 1 to reduce any discomfort for the patient caused by the edges of adjacent blocks of different hardnesses.
  • the whole internal foam body of the mattress is enclosed in a closely fitting flexible cover 3 of mattress ticking material which holds the blocks 1 in abutting relationship.
  • a zip 4 in the side of the cover 3 is provided for removing the cover if the blocks 1 are to be replaced or cleaned.
  • a further feature of the cover 3 in the embodi ⁇ ment of Figure 1 is a multiple-layer upper portion providing an escape path for moisture accumulated in the cover.
  • the mattress ticking preferably has a water ⁇ proof upper surface, and this is covered by an outer sheet 5 of ventile material such as Gore-Tex (Registered Trade Mark) and a sheet 6 of water vapour transmitting material, the latter conducting any accumulated moisture ' " * to " the edges of the mattress where openings 7 are pro ⁇ vided.
  • ventile material such as Gore-Tex (Registered Trade Mark)
  • a sheet 6 of water vapour transmitting material the latter conducting any accumulated moisture ' " * to " the edges of the mattress where openings 7 are pro ⁇ vided.
  • this is but one possible arrangement, and perspiration and incontinence can be dealt with by alternative means such as loose covers which do not form part of the mattress.
  • FIG. 1 has square section foam blocks 1.
  • Two exemplary arrangements of these blocks are shown in Figs. 2a and 2b, the relative hard ⁇ nesses of the blocks being shown by symbols explained in Fig. 2c.
  • Fig. 2a shows a typical arrangement for a patient with the following condition: Reduced Anterior-Posterior Curves, Periostitis (both feet) - Calcaneum.
  • the arrangement of Fig. 2b is suitable . for a patient with Exaggerated Anterior-Posterior Curves.
  • a feature which is common to both arrangements is the relatively hard side edge portions produced by the rows of firm blocks on either side of the central region of the mattress.
  • a mattress in accordance with the invention may comprise a main body of foam having several voids which are filled by foam insert sections of different hardnesses. Examples of such a mattress are shown in Figs. 4 and 5.
  • the mattress interior shown in Fig. 4 has a main foam section 8 with a series of parallel transversely extending channel voids filled by corresponding shaped removable elongate insert sections 9 of a different hardness or hardnesses.
  • three of the insert sections are shown partly removed.
  • FIG. 5 Another embodiment is illustrated in Fig. 5, with cylindrical insert sections 10 (some shown partly removed) in corresponding cylindrical voids extending from the bottom face to the top face of the main section 11.
