Definitions

  • the invention relates to a mattress system according to the preamble of claim 1.
  • a mattress system with a fluid container offers improved comfort when compared to a mattress that only uses padding material made of solids.
  • the surface of the liquid container adapts to the body shape by displacing the liquid as a function of the partial weight of a person lying down. This creates a more even back pressure on the overlying body surface. This property benefits particularly bedridden persons in need of care, who tend to develop pressure sores.
  • the restriction of the liquid container to a central part of the mattress system reduces the volume of the required liquid compared to a waterbed mattress and thus the weight of the mattress system. Furthermore, it is avoided that, when the head part, middle part or foot part inclines, liquid flows out of the respective higher regions of the mattress system into deeper regions and thus reduces the upholstery of the higher regions.
  • the invention is based on the object to improve a mattress system in that its weight is further reduced, a drainage of the liquid from higher regions is reduced at inclinations and that the body of a reclining person better when changing the inclination of parts of the mattress system is fixed.
  • At least one liquid-absorbent, storage-and-dispensing mat is arranged in the liquid container.
  • This mat forms a stabilizer which reduces the tendency of the liquid to escape under pressure. This happens because the mat is endeavored by elastic properties and by capillary action to absorb liquid and vollzusaugen.
  • the mat with the liquid absorbed thus provides resistance to pressure on the liquid container. Only when this resistance is overcome by increasing the pressure does the mat release the stored liquid.
  • the liquid is thus largely left in place even under pressure or inclination, ie tilting of the liquid container.
  • a reduction of the upholstery of the upper regions by Leakage of the liquid and slackening of the shell of the liquid container is thus avoided.
  • the amount of liquid and thus the weight can be limited to a minimum volume.
  • the volume of the material of the mat reduces the liquid volume of the liquid container.
  • Liquid container arranged and the surfaces of these mats correspond approximately to the base of the liquid container.
  • the mats can easily move each other and so also perform small bending radii without kinking.
  • the mats optimally fill the volume of the liquid container and can not slip off one another.
  • the mats can be made of polyester fleece.
  • This material is chemically resistant to liquid additives, flexible, absorbent and elastic.
  • the liquid may be water, gel or water with a gelling additive.
  • the viscosity of the liquid can be changed and adapted to the needs of a person lying down.
  • the dimensions of the liquid container may have a width between 70 cm and 1, 10 m, a length between 1, 10 m and 1, 40 m and a height between 4 cm and 1 1 cm.
  • the footboard and the headboard may each have a width between 70 cm and 1, 10 m, a length between 20 cm and 50 cm and a height between 4 cm and 1 1 cm, the total length of the mattress system being the sum of the lengths of footboard, Middle part and headboard between 1. 90 m and 2.10 m.
  • standard designs can be created that provide optimal comfort for the majority of people. Within the specified ranges, however, custom-made products can also be created to supply even short-lived or very tall people.
  • the foot part and the head part may consist of a foam filled with foam or foam plates shell.
  • this embodiment also offers adaptation properties which, while not approaching those of a liquid container, allow a pressure equalization on the contact surfaces of the stored limbs and of the head.
  • the foot part, the middle part and the head part are arranged in an openable and closable cover and designed as a support on an existing bed mattress.
  • the liquid container four parallel mats are arranged and the foot part and the head part have a length of 40 cm, a width of 90 cm and a height of 6 cm and the liquid container of the middle part has a length of 120 cm, a width of 88 cm and a Height of 5 cm.
  • the liquid container on an additional safety cover.
  • the foot part, the middle part and the head part are arranged in a flexible body and formed as a separate mattress instead of an existing bed mattress. in the
  • Liquid container six parallel mats are arranged and the foot has a length of 30 cm, a width of 73 cm, a height of 9 cm, the headboard has a length of 40 cm, a width of 73 cm, a height of 9 cm and the Liquid container of the middle part has, together with an additional safety cover, a length of 135 cm, a width of 73 cm and a height of 9 cm.
  • the foot part, the middle part and the head part on a common coating on which is connected to the flexible body.
  • the liquid container may be made of a vinyl material.
  • the flexible body is made of a foam, preferably Neopolen. This is a commercial material from BASF, for which a trademark is registered.
  • a heating surface can be arranged below the liquid container.
  • the heating surface is part of a thermostatically controlled heating system which heats the normally room-temperature-accepting liquid to such an extent that the surface of the mattress assumes a comfortable temperature between room temperature and body temperature.
  • the foot part, the middle part and the head part can be arranged on a porous mat, by means of which condensate can be discharged laterally.
  • This mat ensures that condensate is not enriched by Wegausplasticstungen in the material of the mattress system, but can be discharged to the outside and disposed of.
  • the foot part, the middle part and the head part together with a bed mattress or a body are adjustable in height or inclination, the way that the foot part, the middle part and the head part rests in any height position or inclination of the bed mattress or on the body , Due to their flexible nature, the foot part, the middle part and the head part as a support on an existing bed mattress or in a body allow full control of all adjustable positions of an adjustable bed frame.

  • the middle part 12 comprises a liquid container 16 made of vinyl material in a safety envelope 22.
  • a liquid 18 mats 20 which consist of polyester fleece and have liquid-absorbent, liquid-storing and liquid-dispensing properties.
  • Fig. 3 four parallel superimposed mats 20 are shown and this number is also present in the edition of FIG. 1.
  • FIG. 2 there are six mats 20 lying parallel one above the other.
  • the base area of the mats 20 approximately corresponds to the base area of the liquid container 16, so that these mats 20 can not slip off one another. At a bend of the liquid container 16 but they can slide on each other and take tight bending radii without kinking.
  • the stored volume of liquid thus remains in the mats 20.
  • the mats 20 ensure that the liquid 18 in the liquid container 16 can move only very sluggishly and thus largely retains its position even when tilting the lying surface of the upper body or the legs of a person in an adjustable bed frame with a bed mattress.
  • the viscosity of the liquid 18 can be changed by additives and thereby a more viscous behavior similar to gel can be achieved.
  • the foot part 10, the middle part 12 and the head part 14 are arranged in a cover 28 which holds the three parts together.
  • This cover 28 is openable via zippers or hook and loop fasteners and lockable to access the To obtain liquid container 18.
  • the coating 28 can be washed by itself. For reasons of hygiene, it is made of a material that is compatible with cooking laundry.

  • the mattress system for light and normal weight persons is arranged as a support on a bed mattress 34.
  • the additional weight is essentially determined by the amount of liquid 18. This is here about 60 I.
  • the increased load is absorbed by a conventional bed mattress 34 and a conventional bed frame 36 normally without reinforcing elements. Adjustable beds in hospitals and old people's homes also absorb the increased burden.
  • From the mattress system here the foot part 10, the middle part 12 and the head part 14 are shown.
