Definitions

  • An inflatable shaped structure comprising an assembly of pneumatic tubular elements, characterized by the combination of a number of inflatable tubes made from elastic material and a fabric casing forming adjacent elongated cells which contain the tubes, each pair of adjacent cells having plane sides. joined by stitching along at least one generator to the vicinity of a continuous wall which closesthe cells.
  • Such a structure will only support relatively weak inflation pressures, of the order of 200 g/cm (2.84 pounds per square inch) for example, and provides no continuous plane surface.
  • the structure of the invention can support inflation pressures which may reach, for example, several kg/cm (1 kg/cm 14.2 pounds per square inch).
  • the cells are in the form of square-section pipes, closed on one side by a sheet of fabric to which they are stitched, and at least one second line of stitching joins adjacent cells on the opposite side, forming plane sides in mutual contact between the cells, which act as braces after inflation.
  • FIG. 1 is a perspective view, with a transverse section, of a shape conforming to a preferred mode of execution of the invention
  • FIG. 2 is a section of a leg dressed in an orthopaedic costume using such a shape
  • FIG. 3 is a back view of such a costume
  • FIG. 4 is the front view.v
  • FIG. 1 shows a part of an elongated section comprising. by way of example, three latex tubes 1-3 contained in a fabric casing.
  • the latter consists of a plane side 4 and three parts 5-7 forming pipes.rThe parts 5-7 are stitched to the side 4 at 8, 9, l0, 11, 12 and 13. They also are stitched to each other, on the one hand in the vicinty of the side 4 (at and 11, for example), and on the other hand at their opposite side (at 14 and 15, for example). This results in the adjacent plane sides of the pipes being in mutual contact and acting as braces.
  • Zip fasteners may be provided to allow the tubes to be threaded in the casing, previously sewn 2 so as to be an integral part of the assembly to which they are applied.
  • FIG. 2 shows a leg 16 of an orthopaedic costume in which each leg is provided with two sections 17 and 18.
  • the section 17' comprises three tubes and is intended for application to the back of the patients leg, while the section 18, with only two tubes, is applied to the front part of the leg.
  • each'tubular cell has a length which upon inflation of the infaltable tubes 1,
  • the rigidity is very much greater'than would be the case if the tubes were completely separated from each other.
  • the fabric used is an aerated linen and preferably fireproofed.
  • the structure is then permeableto air, which is important in the case of an orthopaedic costume. It is clearly much lighter and more flexible than a metal or plastic frame, yet possesses sufficient rigidity to replace them in most cases.
  • the orthopaedic costume shown in FIGS. 3 and 4 made from a light strong fabric, aerated and preferably fireproof, consists of a garment fitted around the legs and the body up to a certain height. It is supported by shoulder-straps or other means, not shown, and can be puton easily thanks to zip fasteners 19, 20 and 21 (FIG. 4.) or otherv quick fastenings, so positioned that it can be laid flat when the fasteners are open: the user can then lie on the costume and put it on unaided.
  • lacings 22, 23 allow adjustment for differing body sizes, so as to fit closely without impeding the circulation.
  • Two openings, posterior 24, and anterior 25, are provided so that the femoral artery will not come under any pressure, which would cause serious problems in the case of prolonged wearing of the costume.
  • This arrangement is not limitative; nor is the number of tubes which comprise each tubular section.
  • the ante rior tubular sections FIG. 4 are shown with three tubes in their upper part and two tubes in their lower part. It may be preferable in some cases to prolong the third tube to the bottom of the section.
  • the tubes are closed at either end, as is the casing, and are joined to each other and to the tubes of the other sections of the costume by a flexible tube 32 (FIGS. 3 and 4).
  • a feeding device (not shown) comprises preferably a micro-valve, a striker and a valve fixed to the tube 32.
  • a bottle of carbonic gas or a compresser with a presl5 sure-reducer may be joined to the valve to ensure inflation.
  • the inflation pressure needed to ensure bodily sup port for an adult is of the order of 2 bars or 29.4 pounds per square inch.
  • the costume thus inflated exerts a light pressure on the members, which suppresses hypotension.
  • An inflatable shaped structure comprising an assembly of pneumatic tubular elements, characterized by the combination of a number of parallel inflatable tubes made from gas tight elastic material and a fabric casing forming adjacent elongated cells which contain the tubes, each pair of adjacent cells having plane sides joined along at least one side to the vicinity ofa continuous wall which closes-the cells characterized in that the cells have the form of square-section pipes, closed on one side by a sheet of air permeable fabric to which they are stitched, and by at least a second line of stitching which joins adjacent cells on the opposite side, forming plane sides in mutual contact between the cells, which act as braces after inflation.
  • An orthopedic brace of high pneumatic rigidity comprising:
  • each said cell having radially extending sidewalls in contact with like sidewalls of each adjacent cell;
  • each said sidewall to said fabric to form elongated braces some of which are of double fabric thickness and all of which extend parallel to the long axes of said tubular wall structures;
  • means including gas-impervious wall structure for induces rigidity of said tubular wall without increase in inward pressure upon said extremities sufficient to impede blood circulation.
  • tubular cells are each of generally rectangular shape before inflation, said fabric of said tubular enclosures forming corresponding wall portions of each said cell, and means securing each said sidewall to said fabric of said tubular enclosures.
  • An orthopedic brace of high pneumatic ridigity for an extremity of the body comprising:
  • extremity enclosing means adapted for close contorfitting; a tubular wall structures, on the outer surface of said enclosing means, at least one of which is adapted to be disposed in front of and another of which is adapted to be disposed behind the knee; each said tubular wall structure being a dimensionally stable fabric casing having therein at least a pair of elastic inflatable tubular cells closed at both ends and extending lengthwise of said extremity;' each said cell having radially extending sidewalls in contact with the sidewalls of an adjacent cell; and
  • means including gas-impervious wall structure for inflating said tubular cells to a pressure which pro Jerusalem rigidity of said tubular wall structures without increase in inward pressure upon said extremities sufficient to impede blood circulation.
  • extremity enclosing means of flexible sheet material adapted for close contor-fitting
  • tubular wall structures of flexible sheet material on the outer surface of said enclosing means at least one of which is adapted to be disposed in front of and another of which is adapted to be disposed behind the knee;
  • each said tubular wall structure having therein at least two tubular cells closed at both ends and extending lengthwise of said extremity
  • each'said cell having a radially extending sidewall in contact with a like sidewall of an adjacent cell
  • a costume according to claim 7 in which the flexities sufficient to impede blood circulation. 5 ble sheet material of the extremity enclosing means is 8.
  • the orthopedic bracing costume of claim 7 in permeable to body fluids and vapors. which said enclosing means in the region of the crotch v
