EMBODIMENTS

[0031] FIG. 1 shows a schematic view from above of a rescue stretcher 1 according to at least one embodiment of the present invention, wherein the support litter 2 as well as the cold protection unit 4 comprising the blanket-like heat maintaining element 5 and the bodily fluid-absorbing substrate 6 detachably fixed thereon, form a cold-insulating, envelope-like bedding 7 for the person to be rescued. The envelope-like bedding 7 can be closed along longitudinal edge 8 lying opposite each other by means, for example, of a closure 16, which is a hook and loop fastener, or a first zip fastener in such a way that the upper body, in particular the head of the person to be rescued comes to lie in an opening area 9 of the envelope-like (mantle-like) bedding 7 that is accessible from outside.

[0032] As shown in FIG. 1 on the outside of the support substrate 2 six carrying loops 11 are attached in a tear-resistant manner in such a way that on the formed envelope-like bedding 7 on each of both longitudinal sides 12 three of the carrying loops 11 are positioned opposite each other, which on each longitudinal side 12 of the envelope-like bedding 7 are each arranged at an equal distance from one another, so that the person to be rescued held in the envelope-like bedding 7 of the rescue stretcher 1 can be carried by six rescuers.

[0033] In a different embodiment of the rescue stretcher 1 shown in FIG. 2, at the foot end 13 thereof a removable and/or adjustable foot sack 14 is attached to the rescue stretcher 1 in such a way that the feet of the person positioned in the envelope-like bedding 7 of the rescue stretcher 1 can be accommodated in the foot sack 14 and the person can, in particular, be carried secured towards the bottom in the envelope-like bedding 7 in the oblique or upright transporting position of the rescue stretcher 1. In the form of embodiment shown in FIG. 2, seen from above the upper part 15 of the foot sack 14 is in two parts and is closable along the centreline by means of a second zip fastener 26. For example, the dimensions of the foot sack are approximately 35 cm30 cm15 cm.

[0034] FIG. 3 shows a schematic cross-section of a further rescue stretcher 1 according to at least one embodiment of the present invention wherein on the inner receiving surface 3 of the support litter 2 of the rescue stretcher 1 the cold protection unit 4 is positioned as the envelope-like bedding 7. The latter is formed by the blanket-like heat maintaining element 5 which, for example, can comprise a layer of a maximum of three metal-coated cold protection films connected to each other by elastic threads, and the bodily fluid-absorbing substrate 6 replaceably positioned on its inside. The latter can, for example, be a highly absorbent non-woven sheet with an absorption volume of, for example, 4 litres of bodily fluids. The envelope-like bedding 7 is, as shown in FIG. 3, closed through interlinking hook and loop fastener closure elements 17 which are positioned in the area of the longitudinal edges 18 of the blanket-like heat maintaining element 5 on its undersurface or on the lowermost layer of the metal-coated cold protection film 23 of the latter.

[0035] As shown in FIG. 4 illustrating a schematic cross-sectional view of a part of a further rescue stretcher according to at least one embodiment of the present invention, the blanket-like heat maintaining element 5 of the cold protection unit 4 is formed of a layer of three metal-coated cold protection films 23 which are connected to each other by elastic threads 24. The undersurface 25 of the cold protection film 23 at the bottom of the layer is detachably connected to the inner receiving surface 3 of the support litter 2 by means of adhesive points or adhesive strips 27 positioned at a distance from one another or through full-surface adhesion. On the upper surface 28 of the three cold protection films 23 lying on top of one another in the layer a highly-absorbent non-woven sheet is positioned as the bodily fluid-absorbing substrate 6, in the centre of which a special absorbent core 21 with an absorption volume of up to 8 litres of bodily fluids is integrated. With its undersurface 28 the absorption core 21 is fastened, in a quickly replaceable manner, by means of adhesive points or adhesive strips 29, arranged at a distance from one another, on the upper surface 28 of the uppermost cold protection film 23 in the layer of the blanket-like heat maintaining element 5.

[0036] FIG. 5 shows a transparent view from above of a vacuum packaging 31 in which a further rescue stretcher 1 according to at least one embodiment of the present invention is vacuum-packed in the folded up state. The rectangular support litter 2, on the longitudinal sides of which at least two carrying loops are fixed, together with the cold protection unit 4, comprising the blanket-like heat maintaining element 5 and the bodily fluid-absorbing substrate 6 replaceably attached thereto, which is detachably fastened to the inner receiving surface 3 of the support litter 2, can be folded together to form a pack 20 with a surface area of approx. 35 cmapprox. 30 cm and a height of approx. 15 cm and the pack kept in vacuum-packed in a vacuum packaging 21 that can stacked in a small area.

[0037] It is to be understood that the embodiments of the present invention are not restricted to the special structures, process steps, or materials disclosed herein, but are extended to equivalents thereof as would be recognized by those ordinarily skilled in the relevant arts.
