    The invention relates to a device for supporting and stabilizing an injured, with a flexible, on the injured or on an injured body part fixable film element, the two films and a granule containing, evacuatable interior aulweist, the two films along the edge and in places in Domes are substantially point-shaped interconnected so that channels remain parallel to at least one side edge.
    Such also referred to as vacuum mattresses and vacuum rails stabilizing means for transport and immobilization of the injured have a shell of an airtight plastic film and a filling of a plastic granules, in particular of foamed polystyrene beads, and after adjustment and fixation to a sedentary body part by means of a mammal pump be evacuated. This leads to a dense packing of the loosely filled granules and thus to a stiffening of the flexible element, which in this way forms a substantially rigid shell or cuff. For a possible universal fixation on the body part fastening straps are arranged in the circumferential direction of the body part and provided with conventional adjustable connection fittings. Vacuum mattresses and rails are mainly suitable for horizontal use. When used in a non-horizontal position, such as seated casualties, there is a risk that the filling will form a thinner layer in a higher area, or even be absent, because it has shifted from top to bottom during handling. It has therefore been proposed (US Pat. No. 5,154,185 A) to subdivide the interior space into narrower chambers by means of horizontal partitions, wherein the partitions have apertures which are just so large that parts of the filling can only be forced through manually.
    From WO 99/16392 A a device of the type mentioned is known, which is also suitable for an upright transport of an injured person, wherein an upper body support cushion and a headrest cushion can be fastened to a stiffening frame. The cushions each consist of two air-tight foils which are joined together along their edges and at three points inside.
    The internal connections hinder the free movement of the granules, so that it remains substantially in place despite the upright use.
    Apart from caused by the internal connections difficulties in the production of the support facilities inevitably everywhere there are areas without granules where the two films are directly connected and thus areas where despite the vacuum stiffening of the support is poor and unfavorable mobility preserved.
    WO 01/30280 has proposed a solution in which the granules have been filled into insert elements divided into chambers, which are made of an air-permeable material and, after filling, are inserted into the film element. In this case, an approximately uniform granular layer in the entire support means can be achieved if two such insert elements are arranged offset one above the other within the films.
    The invention has now set itself the task of finding a practicable compromise, which represents a simple, material-saving production, a satisfactory, full-surface stiffness of the evacuated support element and a rapid and the requirements corresponding adaptability to the circumstances.
    According to the invention, such a compromise is achieved in that the inner connections are arranged in a four-point grid.
    It has been shown that compounds which are distributed in a four-point pattern over the entire film element, due to the friction between the particles of the granules are completely sufficient to maintain an approximately uniform layer thickness even in a vertical arrangement, but with a manual displacement of particles to make it relatively easy to adapt to the site. The preparation of punctiform compounds can be used in the commonly used weldable
    Plastic films from the outside, and the filling with granules can be achieved according to the invention in a simple way that inserted into each channel a filling lance and granules through the filling lances, the filling lances are pulled out again according to the filling progress, and that finally the films on the open connected to the upper transverse edge.
    Since the filling lances or tubes protrude in a row next to each other from a filled with granules VorratsbehäHer down, preferably to be filled foil elements are pushed from below onto the filling lances and lowered again as the filling progresses.
    Of course, the compounds arranged in the four-point grid also have the disadvantages mentioned at the outset, namely that no granules can be present at each connection point and that the connection points in each row or column represent a line-shaped weak point along which the stiffness after evacuation is lower than in FIG remaining areas. However, due to the localized nature of the punctiform junctions and the relatively large spacing between the junctions through the intersecting channels, sufficient strength of the evacuated sheet member is maintained. The channels located between the joints have, for example, a width of about 10 cm and a thickness of about 3 cm, and the filling consists mainly of granules of foamed polystyrene with a weight between 20 kg / m3 and 70 kg / m3 , in particular 60 kg / m3, wherein the average diameter of the individual particles between 0.4 mm and 5 mm, in particular between 0.5 mm and 2 mm. A preferred embodiment of the connection provides that the four-point grid is oblique to the channels, wherein the four points are in each case in particular at the corners of a square. The distance of the connecting points in the longitudinal and transverse direction is thereby increased to the length of the diagonal, and the stability is good in both directions.
    Hereinafter, the invention will be described in more detail with reference to the figures of the accompanying drawing, without being limited thereto. They show: • »· · t **« · ·· «* • · · * * Μ · 9 9 · * 9 9 · · · V« f · 9 9 *
    1 is a schematic view of a rectangular foil element,
    Fig. 2 is a section along the line II-II of Fig. 1 and
    Fig. 3 is a schematic representation of the filling of the film element of Fig. 1 with granules.
    A film element 1, which is suitable depending on the size and shape for immobilization and stabilization of an injured body part, such as a broken arm or leg, or an injured person has two films 2 of an airtight plastic, for example, a polyurethane, along along the edge circumferentially and connected to each other at points 3 inside, in particular welded. The interior 4 contains a granulate 7 made of a lightweight plastic, in particular of a foamed polystyrene, wherein the diameter of the individual balls is in particular between 0.5 and 2 mm.
    One of the two foils 2 is provided with a valve, not shown, via which the trapped air in the interior 4 can be sucked, whereby the loosely filled and displaceable in the interior 4 by external action or displaceable granules 7 is transferred into a dense packing, the the film element 1 stiffened sufficiently to prevent movement of the injured body or body part. Since the film element 1 can not only be used in a horizontal position, the connection points 3 are arranged in the interior so that the granules also when lifting the film element 1 or when used in a vertical position, such as the upper body stabilization of a seated injured, not down can slip, but remains approximately evenly distributed. The arrangement of the connection points 3 follows a four-point grid, as can be seen from the dashed lines 5 shown in broken lines in FIG. 1, wherein the grid lines 5 are shown running obliquely to the side walls of the film element 1. However, the grid lines 5 can also be parallel to the side edges as well. The distance between each two connection points 3 is preferably the same size, that is, the grid is square, possibly rhombic, and is about 10 cm. The dimensions and arrangement may vary somewhat, but in any case they are such that continuous, parallel channels 6 remain in the longitudinal direction of the film element. Such a film element can be produced as follows:
    Two cut into the appropriate size slides 2 are welded together at three side edges and at the predetermined by the four-point grid connection points 3 inside, so that an open-top bag-like structure is formed. As can be seen from FIG. 3, filling lances 9 parallel to one another or filling tubes are introduced into the channels 2 of the film element 1 which is open at the top and emanate from the bottom of a granulate 7 containing container 8. If the bottom outlets, not shown, of the container 8 are opened, the granulate 7 trickles down through each filling zone 9 into the film element 1, which is lowered slowly downwards, and thereby fills with the granules 7. Subsequently, the films 2 are also connected along the upper edge. As can be seen from FIG. 3, the filling lances 9 can pass over the entire height of the film element 1, the joints 3, and the filling is distributed during lowering of the film element in the free spaces between the channels 6, which lie directly between two superimposed joints 3 ,
