Definitions

  • the invention relates to a mattress for bedsores with at least one two formed from foams of different compression hardness Layered mattress core.
  • pressure ulcers are skin ulcers that develop can, if bedridden people are in a position for a long time and the contact pressure is increased in certain areas of the body. There can there is an undersupply of blood in the relevant outer tissue regions come. The cells die and an ulcer forms. To do this To prevent or treat them therapeutically, it is known mattresses like this to design that the pressure load selectively or over larger areas is reduced. In one from the German utility model 296 04 831 known mattress this is to be achieved in that the mattress a mattress core from a comparatively hard hard Foam material and a pad made of a temperature foam.
  • the temperature foam shows one between the room temperature and the human body temperature range of softening, so that when the foam is pressed by a warm one Body softening is greatest in those areas where the highest load. Therefore, the body partially sinks into the foam one that is larger in less heavily used areas Compression hardness retains, so that a large-area support is created. The wished However, the goal of maximum pressure relief is only partially achieved because the body in the highly stressed areas down to the bottom Layer of the harder foam sinks and the pressure relief is reduced.
  • the object of the present invention is to provide a mattress of the type mentioned at the outset which is the best possible Pressure relief guaranteed under all circumstances. In particular should be prevented that pressure peaks occur at certain parts of the body.
  • the invention is based primarily on the idea that the best possible Pressure relief while maintaining the orthopedic support function the mattress can be reached if a soft storage if necessary can be combined with a hollow bearing.
  • the one mattress core with at least two Layers of foam with different compression hardness at least one from the mattress core to form one upwards open recess has removable material block.
  • Prefers is a plurality of removable blocks of material with adjacent Side surfaces arranged side by side to form at least one block zone, the individual blocks of material expediently essentially are cubic or cuboid.
  • a first block zone with, for example, three times four blocks with a square Base area of 15 to 25 cm side length in an area that one in the longitudinal direction from about the lower back to the knees extends the person lying, be arranged.
  • a second Block zone with, for example, three blocks with a rectangular base area with side lengths of 50 to 70 cm and 10 to 20 cm, the blocks with its longer side arranged transversely to the longitudinal extent of the mattress in the head and shoulder area of a person lying on the mattress be arranged.
  • a lower layer of the mattress core consists of a polyurethane foam, preferably of polyether foam, with a density of 40 to 55 kg / m 3 and a compression hardness of 150 to 180 N according to the standard EN ISO 2439, method B ("ISO 2439B ").
  • an upper layer of the mattress core made of a viscoelastic foam with a density of 40 to 80 kg / m 3 and a compression hardness of 60 to 120 N according to ISO 2439B.
  • the layer of viscoelastic foam preferably has a thickness from 5 to 7 cm, so that on the one hand a sufficient layer thickness for the Soft storage is available, but on the other hand the sinking depth does not increase is large, so that the supporting effect of the underlying polyurethane layer preserved.
  • the polyurethane layer can have a layer thickness of 8 to 15 cm, so that the sum of the two layer thicknesses within the usual mattress thicknesses. By a relative shift of the two Excluding layers from one another, these are preferably flat with one another glued or welded.
  • the at least a removable block of material in cross section from the top layer and part of the lower layer Opposite one conventional hollow storage, in which the removable blocks the mattress core fully enforce, d. H. when removing a block If there is a continuous opening in the mattress core, one will follow here indentation delimited below by polyurethane material. hereby a body can sink into the viscoelastic layer or will the hollow storage by removing one or more blocks selectively or completely relieved of area, but is always sufficient in cross section Much material is available to ensure the dimensional stability of the layer structure. This also has the advantage that the mattress does not sag and has a longer lifespan.
  • the individual blocks more dimensionally stable if they are made of both viscoelastic foam and polyurethane foam consist.
  • the polyurethane layer increases the dimensional stability of the blocks, what handling especially when removing multiple times and reinserted into the mattress improved permanently.
  • the degree of hardness of the viscoelastic to be used Foam is to ensure a sufficient depth of penetration selected so that it is very compressible. If only Blocks would be removed from the viscoelastic layer in the case of a hollow position, the patient would also lie on the one below Lay on polyurethane layer and the desired benefit of hollow storage would only occur diminished or not at all. But when a certain layer thickness of the polyurethane is also removed, arises a sufficient cavity that ensures optimal pressure relief. The pressure peaks that otherwise occur at the edge areas of the removed blocks avoided by the viscoelastic Foam in the area of the edge of the polyurethane layer on the body hugs a person lying on the mattress and thus the effective one Support area significantly enlarged.
  • the mattress core has areas made of a firmer material on its long sides.
  • These lateral edge areas preferably consist of a polyurethane foam, preferably a polyether foam with a density of 35 to 50 kg / m 3 and a compression hardness of 220 to 300 N according to ISO 2439B and each have a width of 80 to 120 mm.
  • a Pad made of viscoelastic foam provided that the mattress core together with the removable blocks covered.
  • This edition can have a thickness in the range of 10 to 30 mm.
  • the adjoining surfaces of the mattress core and the support complementary profiled for example studded, corrugated or ribbed, so that at Movements of a person lying on the mattress have no relative shifts can take place between the mattress and the pad.
  • the Material parameters of the overlay with regard to density and compression hardness correspond to those of the viscoelastic layer of the mattress core.
  • the Pad hinders the effect of hollow storage when removed from the core Blocks do not, but additionally reduces the risk of pressure peaks at the edge areas of the cavity.
  • the mattress core can be in a dimensionally stable Tub arranged from a nylon fabric and with a breathable Be covered with polyurethane, the middle of a circumferential Overlapping zipper can be attached to the tub.
  • the mattress core 10 shown schematically in the drawing consists essentially of a first, lower layer 12 made of a polyurethane foam, in particular of polyether foam with a density of 40 to 55 kg / m 3 and a compression hardness of 150 to 180 N according to ISO 2439B, a second , Upper layer 14 made of a viscoelastic foam with a density of 40 to 80 kg / m 3 and a compression hardness of 60 to 120 N according to ISO 2439B, and longitudinal edge areas 16 made of a comparatively harder polyurethane foam, in particular made of polyether foam with a density of 35 to 50 kg / m 3 and a compression hardness of 220 to 300 N according to ISO 2439B.
  • the upper and lower layers 12, 14 and the edge regions 16 are glued or welded to one another at their contact surfaces.
  • the mattress core 10 has different zones that the soft and / or hollow positioning of a person for the prophylaxis or therapy of pressure ulcers serve.
  • the upper, viscoelastic layer 14 ensures this basically for soft storage, while the bottom polyurethane layer 12 forms a stable base for orthopedic support.
  • Zone 20 in the head-shoulder area a person lying on the mattress has three blocks 20 'with a rectangular base with side lengths of 50 to 70 cm and 10 to 20 cm, with the blocks with their longer side transverse to Longitudinal extension of the mattress are arranged.
  • the blocks 18 ', 20' consist in cross section from the material of the viscoelastic layer 14 and one Part of the polyurethane layer 12, so that when a block is removed a recess for the hollow storage is created, the mattress core however, is stabilized by the residual layer thickness of the polyurethane layer 12.
  • the viscoelastic layer 14 is in the hollow storage at the edges the recess is strongly compressed, as by means of the dashed line 22 in Fig. 3 is shown as an example. It forms at the transition to the one below Edge 24 of the polyurethane layer 12 a squeeze pad, so that there is a pressure distribution area and on the corresponding Body area of the person lying on the ground a new formation of pressure ulcers is avoided.
  • edge regions 16 made of the comparatively harder polyurethane foam enable improved support behavior when standing up out of bed and while lying in bed.
  • the invention relates to a Mattress for pressure ulcer patients with at least two made of foam layers 12, 14 formed with different compression hardness Mattress core 10. To get the best possible pressure relief from all Circumstances to be guaranteed and pressure peaks during hollow storage To prevent, it is proposed according to the invention that at least one from the mattress core 10 to form an upwardly open recess removable material block 18 ', 20' is provided.
