Definitions

  • the invention relates to a positioning mattress, in particular for hospital beds, consisting of foam with several layers of the same or different specific density and different compression hardness, the lower surface of an upper layer having a corrugated structure which extends into a corresponding corrugated structure of the upper surface of a lower layer and cooperates with this elastically.
  • the spring properties are the same across the length and width of the lying surface in systems with slats and base frames and also the spring mattresses, so that different pressure loads occur despite the geometric adaptation to the body. If the external contact pressure is greater than the pressure of the blood circulation, there are circulatory disorders, which in a healthy person are of relatively short duration during the sleep phase, since the body is continuously rearranged during sleep. A bedridden person who is disabled, for example in an intensive care unit or after an operation, has body pressure points that can lead to a life-threatening condition.
  • the object of the invention is therefore to propose a mattress of the type mentioned, which has a progressive spring behavior depending on the partial load on the parts of the body, which at the same time provides adequate ventilation and breathability over the entire lying surface.
  • the lying surface of the upper layer is divided by longitudinal and transverse grooves or incisions in cuboids of a defined size, depending on the physical load, and the amplitudes A of the waves of the lower layer are greater than the amplitudes B of the waves the upper layer and that the wave crests are each wider than the opposite wave troughs (C> D), such that the waves form air channels, jam each other under load and have a progressive spring action.
  • the corrugated structure of the upper layer can penetrate into the corrugated structure of the lower layer with increasing pressure, the corrugated system also increasing Counterforce develops and thus develops a progressive force curve.
  • the two layers are not glued to one another, so that a movement is made possible between the layers which is braked by the uneven waveforms.
  • the cross sections of the grooves are rectangular, and / or pear and / or teardrop-shaped according to the invention, so that different sized supports of a cuboid and thus different spring force effects are present. At the same time, horizontal air channels of different sizes are created, which significantly promote the breathability of the mattress.
  • the cross-sectional shapes mentioned can be combined as required, for example in such a way that a rectangular groove is provided on the surface, the base of which has a dome or pear shape.
  • the lower layer of the mattress has a higher specific density and strength and thus a lower spring elasticity than its upper layer, so that a progressive increase in spring elasticity is achieved.
  • the layers can also be glued at points. With this measure, however, the following must be observed.
  • a thermal treatment is carried out to disinfect the mattresses, at which temperatures of up to 105 ° C are reached. Different behavior can occur between the adhesive and the foam, which must be avoided as far as possible by selecting the adhesive. The solvent released can also have an adverse effect.
  • the foam of the mattress has open-pore cells in at least one layer, which ensures sufficient breathability in addition to the air channels.
  • the entire mattress is located in an elastic network in such a way that all foam layers are fixed. This completely avoids the use of glue.
  • the net is so elastic that the surface tension of the mattress foam is not increased, but its surface friction is reduced to a minimum. This significantly improves the covering and removal of the mattress cover, since the foam surface exerts a high level of friction on the textile.
  • the lying surface 1 of the foam layer 2 is traversed in the longitudinal and transverse directions with grooves or incisions 4 and 3, as a result of which cuboids 10 are formed.
  • the longitudinal and transverse grooves 4 and 3 have mutually identical and partly different distances, as will be explained in more detail with reference to FIG. 3.
  • the shape of the grooves or the cuts contributes significantly to the resilient property of the cuboids 10 formed.
  • Pear-shaped or teardrop-shaped grooves or grooves with parallel side walls can be formed. Combinations of these forms of training can also be produced, depending on which resilient sizes are desired.
  • the groove can be shaped as a rectangle with a base in the form of a spherical cap or pear.
  • the pear-shaped, dome-shaped and also teardrop-shaped incisions or grooves 7 and 8 form a cuboid with a narrow root or foot region 9, which causes a correspondingly lower spring force.
  • any desired spring force variation can be produced in the required areas.
  • the pear or dome shape provides a correspondingly large air channel, which advantageously promotes ventilation and thus breathability.
  • the mattress consists of two parts or layers 2 and 11, which are connected without adhesive by means of a wave-shaped structure.
  • the wave structure 12 of the upper layer which is located on the opposite side of the lying surface 1, engages in the wave structure 13, which is located on the upper surface of the lower layer 11.
  • the material of the lower layer 11 has a higher specific density and strength and thus a lower spring elasticity than the material of the upper layer.
  • the smaller air channels 15 first close when pressure is applied, as a result of which the contact surfaces and thus the spring forces increase progressively. The same applies if the load increases further until the channels 14 also close. In addition to this advantageous spring action, these air channels also contribute to ventilation and thus to increased breathability.
  • Figure 3 shows the mattress in plan view.
  • the spacing of the grooves or incisions 4, which extend in the longitudinal direction over the lying surface 1, is different in size from the grooves or incisions running parallel to it, depending on the different loads on the different body parts.
  • the distance between the grooves 4 in the central region is approximately the same size over three cuboid areas and decreases towards the edge of the mattress, so that smaller cuboid areas are formed.
  • the outer cuboid areas running around the mattress again have a larger cuboid area, which corresponds approximately to the size of the central areas of each transverse row. This measure increases the seat stability.
  • the spacing of the grooves or incisions 3 extending transversely to the lancing surface 1 is greater in the region of the heavy body parts, namely in the head 16 and buttocks region 17, so that larger cuboids 18 are formed, while in the shoulder and leg regions 19 and 20 of the lying surface 1, the distance between the transverse grooves 3 is smaller, and as a result smaller cuboids 19 are present.
  • the part of the lying surface 1 of the mattress provided for the lighter shoulder area 19 is thus softer than the lumbar spine and buttocks area 17.
  • the mattress is adapted to the different loads caused by the body parts lying on it, so that all the body parts lying on it are carried along and the specific surface load is thereby reduced.
