Definitions

  • the invention relates to a mattress that can be used with a conventional bed.
  • decubitus i.e. lying on those areas in which the body rests with greater weight on the bed. This is particularly the case in the area of the heels, lower back, shoulders and head.
  • the present invention has for its object to provide a remedy for the aforementioned problems, that is, to provide a mattress that gives the sick or old person the opportunity to sleep painlessly, avoid pressure ulcers and / or places of heavy pollution separately to clean or replace.
  • This object is achieved according to the invention by a mattress according to the subject matter of independent claim 1.
  • Preferred developments of the mattress result from the dependent claims, the description and the drawings.
  • the Claims are to be understood as a first attempt to formulate the general presentation of the invention and not as a limitation thereof.
  • the mattress according to the invention contains at least on one side at least one area in which the consistency, at least of the mattress surface, can be changed locally.
  • One side is understood to mean mattresses that have a summer and winter side and that, depending on which side of the mattress faces upwards, offers the sleeper a warmer or better-ventilated pad, the side that faces upwards in the position of use.
  • area is understood to mean a delimited coherent area inside the respective top of the mattress, which is selected such that it coincides with the point in which the feet, the lower abdomen, including the abdomen, are normally in the case of people bedded on the mattress.
  • the hips and pelvis or the shoulder including head come to rest.
  • Consistency of a surface area of the mattress is understood to mean those physical properties of the mattress in this area which are decisive for the comfort of the support, such as strength, elasticity, plasticity, thermal conductivity, absorbency, washability, etc.
  • a changed consistency is, for example, due to the selection of different ones Materials, through a different packing density of materials, through a changed structure in the thickness direction and also by omitting mattress material at appropriate points. By varying the consistency in different surface areas, it is achieved that the mattresses are adapted to the individual problems in the affected areas due to the locally targeted modifications.
  • the hip can develop in hip surgery strong pressure in the pelvic area can be alleviated by a locally limited softer mattress pad, whereas in the case of spinal disc damage, a harder pad in the area of the lower back may be preferred.
  • a locally limited softer mattress pad in the case of spinal disc damage
  • a harder pad in the area of the lower back may be preferred.
  • locally heatable areas or areas with reduced thermal conductivity can provide relief. Localized heavy soiling from saliva discharge from the mouth, bedwetting or vaginal discharge can be removed more easily with smaller machine washable inserts.
  • At least one possibly affected area such as the foot, pelvis, hip, lower back, shoulder and head area
  • a recess each of which contains an insert part which is at least separately removable and replaceable
  • the recess is completely surrounded at its edge by the residual mattress in such a way that it forms an elastically resilient, but inherently rigid frame for the at least one separately removable insert part, and the mattress surface, as long as all insert parts are inserted, forms a preferably continuous contact surface with their surface.
  • “preferably continuously” is understood to mean that elevations and indentations of the mattress surface, which can be formed by a special design of the insert parts and which are used for the special storage of certain body areas, form an essentially smooth and continuous surface. In certain embodiments of the mattress, however, it is provided that the elevations or indentations of the mattress resulting from the insert parts used have a discontinuous course. A structure of the mattress surface according to the invention formed by such elevations and indentations is not shown in the drawings shown.
  • the connection of the insert parts to one another and / or to the mattress is preferably designed in such a way that the insert parts can be easily removed from the mattress and can be reinserted firmly.
  • mattresses are provided, the individual cutouts of which are each filled by a plurality of cylindrical insert parts, the insert parts being able to have any desired geometric cross sections.
  • These mattresses can be changed in a variety of ways and are therefore particularly suitable for being adapted to the particular physical characteristics. Combinations of kidney and ellipsoidal cylinder parts are possible among many others in order to achieve an optimal adaptation to personal sleeping habits. It proves particularly favorable if the cylinder axis runs perpendicular to the lying plane and the distance between the two cover sides corresponds approximately to the mattress thickness, since this facilitates the combination of the individual cylindrical insert parts.
  • foam cylinders are each somewhat compressed in the inserted state, so that they are held in place by the lateral pressure on one another and the friction between their side surfaces without additional fastening, as long as they are still at opposite points against one another and / or against the adjacent mattress areas are clamped.
  • the recess in the mattress provided for receiving the insert parts additionally contains a liquid-impermeable trough.
  • a liquid-impermeable trough This is preferably designed such that it occupies a defined partial area or the entire recess.
  • the wall of the tub is chosen so thin that the insert parts to be received by the recess in the tub when this fills the entire recess or can be partially accommodated in the tub or outside of it if the tub occupies only a portion of the recess.
  • the tub is preferably made of a thin rubber skin or a flexible plastic basin.
  • different insert parts are made from different materials, which differ in terms of strength, thermal conductivity, plasticity, absorbency, washability, etc.
  • an insert part is conceivable, the core of which and the outer surface side of the mattress are made of a very absorbent and easily machine washable material and the other surface sides are made of water-impermeable material.
  • the insert parts are releasably connected to one another and to the mattress by means of adhesive fasteners, for example by means of Velcro fasteners.
  • the at least one area is equipped with a plurality of chambers which can be fed individually with different fluids, such as gases, liquids or sand, etc.
  • the different lying properties of the chambers can be achieved through material combinations or through density and pressure variations in the individual chambers. It is also possible to load the individual chambers with materials of different temperatures, in which case the chambers should have a thermally conductive material on the lying side and the other chamber sides should be made of heat-insulating material in order to prevent rapid heat or cold diffusion. Of course, there is also the option of heating the chambers individually and separately.
  • the locally changeable areas are particularly preferably to be arranged in the area of the foot, pelvis, back and / or head, since these are the areas most frequently affected.
  • the trough or recess runs essentially perpendicular to the longitudinal edge of the mattress over most of its width.
  • the recess can also be designed in the form of a segment of a circle, so that the person bedded on the mattress, when he moves from a position corresponding to the longitudinal direction of the mattress into an inclined position, does not have to perform a longitudinal displacement along the mattress in order to still be comfortable To achieve absorption of the feet in the area.
  • a rectangular configuration is preferable and in Head area a circular or concentric to the head arrangement.
  • special insert parts are used for the storage of certain parts of the body which, when inserted into the recesses provided in the mattress, cause elevations and indentations in the surface of the mattress. These elevations and indentations also partially create discontinuities in the surface course of the mattress.
  • FIG. 1 In the exemplary embodiment of a mattress 1 shown in FIG. 1, starting from its upper side 2, three separate areas 3, 4 and 5 are provided which are occupied in the inner area of the mattress, each of which contains at least one separately removable insert.
  • the area 3 occupied in the head area of the patient has a rectangular shape and contains three insert parts 6, 7 and 8 which form one Complement the rectangular area, the middle insert 7 having a circular or oval cylindrical shape. Adjoining it laterally are two insert parts 6 and 8 which are mirror-symmetrical to one another and which have a corresponding circular segment-shaped boundary on the side facing the insert part 7.
  • Each of the three insert parts 6, 7 and 8 can be removed separately and in the inserted state can be attached to the other insert parts and the rest of the mattress by means of interlocking Velcro elements, which are not shown in the drawing. If the insert parts are made of foam and they are made with a certain excess compared to the recess 3 of the mattress 1 delimiting the area 3, an additional fastening between the insert parts and / or the mattress is unnecessary.
  • the area 4 of the mattress 1 provided for receiving the pelvis and / or back of a patient consists of a recess of relatively extensive area with a rectangular shape, which is filled by a grid-like arrangement of a plurality of insert parts 9 of the same cuboid shape, each of which can be removed separately is, so that a recess can be produced at any desired position and in any desired size or shape, which starts from the top 2 of the mattress and makes it possible to keep a patient's pressure ulcer free from the back pressure of the mattress.
  • the area 5 is occupied at the foot end of the mattress and contains a one-piece insert part 10, which is also detachably held in the remaining area of the mattress.
  • the insert part 10 can also be replaced by a multiplicity of cylindrical insert parts, similarly as is provided in the area 4.
  • the partially sectioned longitudinal cross-sectional view of FIG. 2 shows various variants for the design of the insert parts 9 accommodated in one of the areas, in the present case in area 4. All have in common that at least some of the insert parts penetrate the entire mattress 1 in the thickness direction from its top 2 to its bottom.
  • the insert parts 9 consist of inclined cylindrical identical elements which directly adjoin each other and ensure through the inclined position that the weight of a flat surface gives the feeling of a uniform surface. If the cylinder base surfaces are circular or elliptical, there are continuous ventilation channels between the individual elements, which extend from the underside 11 of the mattress to the top 2 of the mattress, but which cannot be seen in the drawings.
  • the insert parts 9 are cuboids or cylinders with cylinder axes running perpendicular to the base area.
  • the mattress 1 contains an area 4 in which a recess 12 is made, which in the right-hand area shown in the figure completely covers the mattress 1 in the thickness direction interspersed and in the left area only a small piece reaches into the interior of the mattress 1.
  • the recess 12 is filled with a large number of insert pieces with different shapes. In the case shown, these are two insert pieces 13, 14, which only fill the lower area of the mattress, and an insert part 15, which comes to rest over the insert parts 13 and 14 and additionally fills the flat trough of the recess 12 which is occupied in the left area.
  • two insert pieces 16 and 17 are provided, which completely penetrate the entire mattress in the thickness direction, but are each divided into two, the upper region 16a, 17a of the insert parts 16 and 17 having the same thickness as the insert part 15 in the case shown.
  • This configuration Allows versatile variation options for the design of the area 4, for example the top in the area 4 can be equipped with a highly absorbent, disposable or easy-to-clean material, while the remaining insert parts can be provided with different hardness, for example, in order to adapt to special orthopedic To enable requirements.
  • Fig. 3a the entire area is formed by these uniformly filling squares, each of which can be removed individually or in combination with others.
  • Fig. 3b four curvilinear insert parts are provided, of which the middle one has the basic shape of an inverted T, which is delimited by elliptical curves each extending to the edge of the area, which in turn delimit the adjacent areas of the remaining insert parts.
  • This configuration is suitable especially for positioning patients with plastered thighs and / or damaged discs.
  • 3c contains a circular insert part which is surrounded by an annular insert part which in turn is received by a rectangular insert part with a circular central opening. This configuration is particularly suitable for positioning the head of a patient.
  • area 4 contains an absorbent plate-shaped insert 18 and an insert 19 surrounding it all around made of liquid-impermeable material.
  • This embodiment is particularly suitable for patients with incontinence, especially bedwetting.
  • the area 4 shows a further variant of the mattress according to the invention.
  • the area 4 consists of a number of chambers 20 which pass through the mattress in the transverse direction and extend to the surface 2 of the mattress.
  • At the bottom of each of the chambers 20 there is an inlet 21, through which the chambers can be acted upon by a fluid.
  • a hose or pipe 22 is connected to each of the outlets 21, which leads to a control unit 24, which in a manner not shown ensures that the individual chambers can be acted upon individually and independently of one another with a pressurized fluid to different extents , wherein the fluid from a schematically indicated pump 25 is fed to the control unit via a line 26.
  • FIG. 5 shows a longitudinal section through the mattress 1 at the point at which the residual mattress and the area 4 adjoin one another.
  • the mattress 1 contains a stable core 27, for example a spring core or a Rigid foam core can be like a core made of polyether foam.
  • a layer 28 of soft material such as, for example, pencil latex, and above it a body-friendly cover 29, for example of sheep's wool, the mattress 1 also being provided with a cover 30, which on the underside of the mattress 1 also covers recess provided in area 4.
  • the cover 30 may consist of a normal mattress cover or of an air-permeable but moisture-impermeable material.
  • the recess delimited by the area 4 contains a trough 31 lying against the wall.
  • insert elements 9 are accommodated which are made of foam, the lower part 9a generally being made of a harder material, for example polyether foam, and the upper part Part 9b consists of a softer foam, and both parts 9a and 9b are colored differently.
