Definitions

  • the present invention relates to a hygienic mattress intended to be used in hospital care of patients who are bed-ridden during long periods of time, as well as a process for manufacturing said mattress.
  • These patients often are afflicted by bedsores which may be caused by the flat surface of the mattress.
  • These flat mattresses often also are protected by a thin protective cover of a planar plastics material in order to make the mattress waterproof and easy to clean.
  • This thin, waterproof protective cover enhances the disadvantages of the planar mattress regarding the tendency for the patient to develop bedsores.
  • hospitals and in geriatric nursing mattresses are used today intended for patients who are bed-ridden during long periods of time. These mattresses are often complicated to make and expensive to manufacture, and they are therefore not so commonly used as might be wished. Many patients do today easily develop bedsores due to the fact that they lie on even and tight materials.
  • a hygienic mattress consisting of a body or core including one or several layers and a surface layer covering generally the entire upper surface of the mattress which consists of a shaped layer of a cellular plastic, the side of said layer facing away from the core in section having a profiled surface of the form of a so-called egg-carton-shaped hump structure, i.e. having depressions and elevations mutually interconnected by saddle surfaces in such a way that an elevation is surrounded by four depressions in four mutually orthogonal directions, and connected to four elevations by means of said saddle surfaces, the surface of the layer facing the core having a planar surface.
  • the main object of the invention is to manufacture a hygienic mattress which prevents the development of bedsores, and which, if such have been developed by the use of a conventional mattress, facilitates the healing of these at the same time that a water proof mattress is obtained which is easy to keep clean and which is easy to manufacture at a reasonable cost.
  • a hygienic mattress wherein the cellular plastic is of a water repellent type, wherein the surface of the cellular plastic has a cell system which are generally closed to 100 %, forming a surface which per se is waterproof, smooth and water repellent, the mattress thus forming air cushions between the vertically seen lowest points, the hollows, and the saddle surfaces being located between adjacent elevations on which the resting body surface rests, as well as by means of a process for manufacturing the mattress wherein the relatively thin layer of similar plastic with a closed cell system is applied onto a core of polyurethane foam plastic comprising one or several layers by means of for instance glueing, and which core may comprise urethane foam, a core of metal coils or similar.
  • the cellular plastic can be heat-treated by means of hot air in order to close the cells in the plastic to 100 %, whereafter the mattress is cut to a suitable size.
  • Another process is to heat-treat the relatively thin layer of cellular plastic, cut this to a suitable size and to apply this thin layer onto a conventional mattress, for instance of the spring mattress type.
  • the present invention has many advantages.
  • the process is simple, and the invention makes it possible to give the patients a comfortable surface at a reasonable cost, and makes it easier for the staff to clean the mattress, also with cleaning and disinfectant agencies, including alcohol, simultanously that a mattress with a low weight is obtained.
  • It is relatively simple to manufacture hygienic mattresses for different weight classes and sizes.
  • the mattress functions in such a way that the urine is collected in the hollows and the person lies quite dry and does not need to use diapers.
  • the mattress can easily be flushed clean and the bed can be reused immediately. If persons, for instance hospital staff having tired backs due to the lifting and the turning of patients, rest on a mattress according to the invention, tests show that these persons feel an appreciable rest of the back. This is due to the massaging effect of the mattress.
  • the mattress is suitable for patient with wounds such as burns or similar, since air having different temperatures can be circulated in the hollows, and the healing is facilitated since the mattress decreases the contact surface of the body against the bed and distributes the pressure of the mattress in an advantageous way over the whole body, thus minimizing the formation of moisture and heat between the body and the bed.
  • the hygienic mattress has proved to have a service life being about double the service life of a conventional hygienic mattress.
  • the mattress does not need a plastic cover and/or mattress cover. No complicated accessories in the form of apparatuses or motors, requiring reparations and maintenance and which emit disturbing, droning noices, need to be used.
  • Figs. 1 and 2 show the invention wherein the surface layer consists of a profiled cellular polyethylene plastic having a cell system closed to 100 % which entirely surrounds a core or body comprising one or several layers of for instance polyurethane foam plastic.
  • This mattress core can consist of a homogenous block of polyurethane foam plastic or of two or several layers having a surface which is profiled on one side and even on the other side, the layers being located on the top of each other with the profiled surfaces facing each other and with a rigid sheet interposed between the layers, but the core may also comprise a conventional spring mattress.
  • Fig. 3 shows the invention wherein the surface layer of profiled cellular polyethylene plastic only covers part of the core or body 2. It is also shown that the body may comprise several layers, as for instance a profiled sheet 3 of polyurethane foam plastic, or a sheet of polyethene 4 and a sheet 5 of profiled polyurethane foam plastic.
  • Fig. 4 shows different profiles of humps suitable for use in connection with the invention.
  • Fig. 5 shows how the profiled cellular polyethylene plastic having a closed cell system is applied around the core or body 2, is cut and glued onto the core and is heat treated in order to seal the pores to 100 %.
  • the compressed cellular polyethylene plastic is then cut horizontially at about half its height by means of a knife 9, a permanent "egg-carton-like" configuration 10 thus being obtained on one side, and a planar, cut surface on the other side 11.
  • planar side of this layer is moved over a applicator 12 for applying an adhesive, and this surface is then attached to the mattress core, and a slight pressure 13 is applied in order to obtain a good contact so that the surface may be attached to the core.
  • a heat threatment by means of hot air 14 is performed in order to close the cells to 100 %.
  • the core with the glued, water repellent layer is then cut to a suitable size.
  • a block of cellular polyethylene plastic 6 through two profiled rollers 7, 8 which compresses the cellular polyethylene plastic with a great pressure in a zig-zag pattern.
  • the compressed cellular polyethylene plastic is then cut horizontally at about half its height by means of a knife 7 which results in a permanent "egg-carton-like" hump structure 10, i.e. elevations respectively depressions which mutually are interconnected by means of saddle surfaces in such a way that an elevation is surrounded by four depressions in mutually orthogonal directions and is connected to four elevations by means of said saddle surfaces.
  • the profiled, relatively thin layer of cellular polyethylene plastic is then heat-treated and cut into suitable lengths in order to fit a core which is to be covered by the layer.
  • This profiled, thin layer of cellular polyethylene plastic is than applied arround the core and joined for instance by its short ends by means of for instance Velcro tapes, in order the layer may be easily dismountable.
  • the core may comprise a conventional mattress of the spring mattress type, or may be other cushions, used for instance in chairs, sofas, wheel chairs or seats in cars and buses.
  • the distance between the tops in the horizontal direction may be varied in dependence of the weight and the size of the user.
  • a suitable mattress for a desired weight class can be made easily identifiable by colouring for instance the profiled plastic layer 1 in different colours, a blue colour on the profiled plastic may for instance be suitable for the weight class 75 - 85 kg, red for 65 - 75 kg, green for 55 -65 kg, yellow for 45 - 55 kg etc. In this way the storing and handling of the mattress according to the invention is facilitated both in the stores, at the large consumers, i.e. hospitals and institutions for geriatric nursing.
