  • the pressure distribution cushion from individual, air-filled, arranged side by side in parallel There are chambers, which chambers prefer with their longitudinal axis are arranged perpendicular to the longitudinal axis of the lying surface.
  • chambers which chambers prefer with their longitudinal axis are arranged perpendicular to the longitudinal axis of the lying surface.
  • pressure distribution is not inevitable; in another Embodiment can be provided that the longitudinal axis of the Chambers is arranged parallel to the longitudinal axis of the bed surface. Both embodiments can also be combined with one another become. It is advantageous here that parallel to the longitudinal axis arranged chambers on the lateral, outer boundaries to arrange the lying surface or the seating surface to the user to give a lateral hold.
  • These pressure distribution pillows are with appropriate Combined ventilation elements, these ventilation elements are arranged within one or more chambers, or but can be between the chambers.
  • Ventilation elements are located in the respective chamber and no air from the chambers in it Ventilation element can escape. Through this Ventilation elements lead through ventilation openings an air passage from the top to the bottom of the Allow pressure distribution pillow and vice versa.
  • the chambers can be controlled separately and with separate Air pressure can be applied. But it is also one application in groups possible.
  • each chamber will have a corresponding one Line is connected, with all lines in one Pressure distributor converge, in which several shut-off valves are arranged. One opens into the pressure distributor Supply line, which a controlled amount of air into the individual lines distributed.
  • valve actuation of the individual valves in the pressure distributor can individual lines of each Chambers are interconnected or from each other be sealed off to be filled with air or separately to be vented.
  • the longitudinal axis of the chambers of the Pressure distribution cushion perpendicular to the longitudinal axis of the Lying area are arranged and about 1/3 of the lying area in the cover the middle area.
  • Such an arrangement of the pressure distribution cushion on the Mattress core is suitable for appropriate Mattress problems in the lumbar region, in the Fix the coccyx and buttocks area.
  • the entire pressure distribution pillow on top of the mattress can be moved to support for the to form parts of the body to be treated accordingly.
  • the length the pressure distribution cushion can also be designed in this way be that both problem areas - without shifting the Pillows - to be covered.
  • you can use the pressure distribution pillows according to the invention can be achieved, by targeting individual chambers of the pressure distribution cushion deflated and other chambers inflated to create one certain desired body contour on the lying surface generate, which the body lying on it must then accept.
  • the air supply to the individual ventilation chambers can be chosen arbitrarily; in the simplest embodiment all chambers are connected in parallel to each other and lie on a common air supply. It goes without saying possible by arranging appropriate throttle valves Throttle air supply to the individual chambers as well.
  • Such a completed pressure distribution system with Associated ventilation is also most difficult to treat Suitable skin injuries, such as those used in intensive care units Treatment of skin burns are necessary.
  • Air, a gas or a suitable one is the pressure medium Liquid provided.
  • This pressure distribution system can with any Mattresses and any oils can be used and consequently this pressure distribution system either above can be arranged on a mattress and inside or is outside of a shell, or below a mattress can be arranged and then also located inside and outside the mattress cover.
  • the pressure distribution system In all cases where the pressure distribution system is fixed to the Sheath to be connected, it can be provided in the Envelope to provide a corresponding bag in which the Pressure distribution system is arranged.
  • the entire bag is detachably connected to the case and on certain points of the shell is attachable.
  • the pressure distribution cushion 1 consists of four different ones Chambers, namely longitudinal chamber parts 2 and 3 and to cross-transverse parts 4,5, the said Parts hermetically separated from each other by dividers 6 - 8 Are completed. I.e. the air in each Chamber parts 2 - 5 cannot be in the other chamber part escape because appropriate sealing separators 6 - 8 are arranged between the chamber parts 2-5.
  • the invention is not based on the arrangement limited by four different chamber parts 2 - 5, it more or fewer chamber parts can also be provided; it can e.g. one or more cross members 4,5 are also omitted.
  • a further development of the invention also provides that the dividers 6 - 8 are not hermetically sealed between the Chamber parts 2 - 5 are arranged, but that these have defined leakage recesses in order to controlled air transfer from one chamber part to another to enable.
  • this runs lengthwise Chamber part 2 two ventilation elements 9, while in the other chamber parts 3 - 5 only one ventilation element 10 - 12 is arranged.
  • Each ventilation element is in the form of a cuboid, separate element within each Chamber formed, the side walls of each Ventilation element 9 - 12 are hermetically sealed, so that over the ventilation elements 9 - 12 no air from the chambers 2 - 5 can escape into the ventilation element 9-12.
  • Each ventilation element 9-12 has a number of Vents 13 on the shown in Exemplary embodiment in an orderly sequence lie. However, this is not absolutely necessary; this Openings 13 can also be arbitrary over the area of the respective ventilation element 9 - 12 can be distributed.
