DESCRIPTION:
BRIEF SUMMARY
The invention relates to articles such as cradles or surgical neck braces for supporting members or the head of persons or animals.
Numerous articles of this kind have long been known, but they present a certain number of drawbacks. Thus for the immobilisation of a fractured leg the Jeanbrau blind is known which comprises parallel wooden slats interconnected like those of a blind and permits the urgent manufacture of an emergency surgical cradle, but it possesses the drawback of being bulky and necessitates the positioning of a padding for the protection of the injured member. Kramer's splint, formed from metallic latticework, is deformable in only one plane and also necessitates a protective padding the positioning of which is quite lengthy; moreover it is opaque to X-rays. The pneumatic splint surrounds the member and effects it immobilisation by the fact that it is inflatable, but it does not permit of giving regard to a deformation and it is relatively fragile. The Metallic cradle formed of latticework necessitates a protective padding, it does not permit of giving regard to a deformation greater than the width of the cradle, and it is opaque to X-rays.
The purpose of the invention is to realise supporting articles which do not possess the above-stated drawbacks of the articles referred to above.
To this end it has first of all for object a new material from which it is possible to manufacture such articles.
This material is characterised in that it is constituted by a layered panel formed by the assembly of a layer of plastic material in the form of hard foam, a sheet of easily deformable but inelastic metal, a layer of plastic material in the form of flexible foam and a flexible and smooth protective internal sheet. The layer of plastic material in the form of hard foam can be covered, either with an external flexible and smooth sheet in which case the articles manufactured from such a material will be supported by means of bands or straps equipped with fixing means (buckles, "Velcro", etc.), or with a material in flexible loops, such as knitted fabric or brushed fabric, and in this case it will then be possible to utilise straps equipped with elements adapted to hook themselves directly into the said looped material.
Most often the panel and especially the metallic sheet which it includes will be cut out in accordance with predetermined shapes corresponding to the conformations of the various articles to be manufactured, various surgical cradles or surgical neck braces for exemple. In any case as will be understood better hereinafter, in the course of the following statement, it is immediately now understood that the material in question permits of manufacturing articles easy to put into position without precise adjustment, by reason of the plasticity of the product which renders it modellable and consequently of great flexibility in use, especially giving regard to significant deformations of a member, possessing an integrated padding, which articles are solid, light, usable on mountains since they are unaffected by cold, reliable during displacements and transparent to X-rays.
The invention will be better understood on reading of the following description and examination of the accompanying drawing which show, by way of examples, the structure of a panel of material according to the invention and several supporting and protective articles manufactured from such a material.
IN THE DRAWINGS
FIG. 1 represents, in section along the line I--I in FIG. 2, a panel for the manufacture of a surgical cradle according to the invention, for a fractured lower member;
FIG. 2 is a section on a larger scale along the line II--II in FIG. 1;
FIG. 3 and 4 are profile and plan views respectively of a surgical cradle manufactured from the panel according to FIG. 1 and 2, modelled and fixed on a fractured lower member;
FIG. 5 represents from the front a panel (the layer of plastic material in the form of flexible foam and the internal protective sheet of which are assumed to be transparent) for the manufacture of a c
