Definitions

  • the present invention relates to a bedding or seat element, more particularly an anti-decubitus cushion for bedridden persons threatened with bedsore or having bedsores in the seat or another part of the body.
  • US-A-4 225 989 discloses an inflatable mattress with two separate overlapping seats.
  • the upper seat has two series of alternating inflatable tubes while the lower one inflates separately and serves as a base. Aeration is provided by small perforations in some of the tubes of the upper seat.
  • the tubes of the upper seat extend transversely to the longitudinal axis of the mattress (col. 1, line 46; col. 2, line 41).
  • This device certainly tries to soften the contact and the pressure of a wound, or of a vulnerable region of the skin, with the support of the body while preserving with the alternative mattress a certain flexibility at the time of the reversal of insufflation in the tubes. of the upper seat, thanks to the system.
  • This system does not remove this contact and this pressure, which is medically essential.
  • the transverse arrangement of the flanges of the alternating inflatable upper seat can be unpleasantly felt by the patient (crossbar effect), especially if the patient is emptied.
  • US-A-4,206,524 discloses a fundamentally different approach from the document cited above.
  • it is a foam mattress or cushion comprising at least one hole in a predetermined position to be placed opposite a wound to be treated, the dimensions and the hole or holes being adapted to each particular case.
  • An air supply is provided in the hole (s).
  • Adaptation to each case is possible with a foam cushion, but obviously excludes any transformation of the individual foam cushion into a cushion with alternating inflation also individual.
  • the cushion really offered the same advantages as the invention, there would be no reason to make this transformation.
  • this system offers the disadvantage of a constant pressure exerted around the ulcerated area without activating, by a massage, the circulation of blood to the wound.
  • the invention aims to eliminate the drawbacks of the previously known devices described above by alternately ensuring compression-decompression of the areas around the pressure ulcer, while avoiding compressing the pressure ulcer itself and while ensuring ventilation of the wound.
  • the anti-decubitus device of the invention has the additional characteristics, compared to the device of US-A-4 225 989, which are defined in the second part of claim 1.
  • the crown-shaped cushion shown in Figures 1-3 has a fixed part 1 made of polyurethane foam.
  • This fixed part has a corrugated surface 2, coated with a polyethylene sheet 3.
  • the corrugations are concentric and continuous.
  • the bottom of the recesses 4 comprises a second polyethylene sheet 5 which adheres to the first 3 only by the edges 6 and thus forms by inflating a pocket or tube 7.
  • the air is supplied from a pump 8, through a conduit 9 passing through the polyurethane body 1.
  • the pump 8 brings and removes the air and therefore alternately ensures the inflation and deflation of the tubes 7.
  • the cushion In its central part, the cushion has a recess 10 which also leads to an air inlet 11. This has an orifice small enough not to cause an annoying loss when filling the tubes 7, while ensuring ventilation at the level of the recess 10.
  • the air inlet 11 is provided with a valve (not shown) which closes when the pump begins to draw the air out of the tubes 7. Said valve opens, on the contrary, when the pump starts to inflate the tubes 7 or when these are more or less inflated, as required.
  • the thickness of material is obtained by an inflated or full part, of material similar or different from that of the adjoining parts of the cushion.
  • the filling of the hole may or may not be integral with the rest of the cushion.
  • FIG. 4E illustrates a case where the blind recess is also filled with an absorbent material 17 such as cotton wool, gauze or a foam, or else a medicinal product.
  • an absorbent material 17 such as cotton wool, gauze or a foam, or else a medicinal product.
  • the recess can obviously have any suitable shape: round, square, rectangular, polygonal, ovoid, etc.
  • FIGS. 1 to 3 relate to a device ensuring local compression-decompression which comprises a block of foam with corrugated surface coated with a flexible sheet welded to the block at the crests of said corrugated surface, forming thus inflatable pockets or tubes delimited by the hollows of the corrugations and said sheet.
  • these tubes are inflated, their upper parts provide compression.
  • they are deflated, it is the ridges of the foam block which provide compression but at locations offset from the previous ones.
  • FIGS. 5A and 58 illustrate a variant of the previous system, in which the foam block is replaced by a cushion 1 permanently inflated and forming a series of ridges 6 on which a sheet 5 is welded to form a series of inflatable pockets 7 represented deflated in Figure 5A and inflated in Figure 5B.
  • FIG. 7 illustrates a way of nesting the inflatable circuits one inside the other around the recess 22. We also see the air inlet-outlet, respectively 23 and 24, of each of these circuits. Air can also be brought to the recess 22 by a conduit 25.
  • circuits 20 and 21 and the air supply 25 can be obtained by simple superposition and welding of sheets, one designated 26, the other 27.
  • Reference notation 28 designates the weld lines of these sheets.
  • FIG. 9 represents a set of two superimposed cushions 29 and 30.
  • the upper cushion 29 is here similar to that of FIG. 7. It comprises two nested circuits 20 and 21 capable of inflating-deflating alternately, and each comprising an inlet -air outlet 23 and 24 respectively.
  • the lower cushion or basic cushion 30 on the other hand comprises a single set or circuit of tubes and remains inflated 31. Both of them have a recess 22. Fasteners 32 make it possible to secure them to one another . An air intake duct to the recess can be interposed between the two cushions.
  • the base cushion may not have a recess.
  • circuits made up of strands or elongated pockets can also be modified to present series of cells, FIG. 10.
  • a honeycomb arrangement can be obtained from two sheets 40 and 41, the sheet 41 being shaped to present cells 42, these two sheets being welded to each other along weld lines 43 so as to define two independent circuits a and b which will inflate and deflate alternately
  • FIGS. 10A to 10C illustrate the different phases of this swelling-deflation.
  • circuit a deflated and circuit b inflated we pass through an intermediate phase shown in FIG. 10B (circuit a being inflated and circuit b being deflated) to result in the state shown in FIG. 10C (circuit fully inflated and circuit b deflated) and vice versa.
  • FIG. 11 Another arrangement of circuits with cells as shown in FIG. 11 can be obtained from three sheets 40, 41 and 44. As shown schematically in FIGS. 11A-11C, the sheets 40 and 41 delimit a first circuit a while sheets 41 and 44 define a second b. Each of these circuits has at its upper part cells 42.
  • FIGS. 11A-11C also illustrate the process of inflation / deflation of the system, similar to that of FIGS. 10A-10C.
  • FIG. 12A An interesting form of cell manufacturing is illustrated in Figures 12A and 12B.
  • a half-cell x is welded by its edge (at 45) to another half-cell y which has a hole 46 in its center.
  • the edges of the hole 46 are welded to the edges of the hole corresponding 47 of the inflation-deflation circuit.
  • FIG. 13 one sees in perspective a part of another variant of the alveolar cushion.
  • circuits c inflated in perma nence and alternative circuits a and b and swelling-deflation.
  • On each hole 47 of circuits a and b is applied a cell which inflates and deflates at the same time as the corresponding circuit. Note that the cells are staggered.
  • the supply of air to the recess can be done by pipes at the level of the wound, such as the pipe 9 shown in FIG. 1.
  • the supply-exit pipes air can pass through a layer if it is, for example, a block of foam. They can also pass between two layers as in the embodiment illustrated in FIG. 8.
  • Valves can be provided at the start or at the end of the air intake-outlet ducts, as one may not foresee or even foresee d '' other equivalent means.
  • the cushion combines the advantages of known devices while avoiding their disadvantages. It eliminates, by its compression-decompression system, the disadvantages of the "round” of rubber or foam, which exerts on the flesh adjacent to the pressure ulcer a continuous compression harmful to the blood circulation. On the other hand, the invention maintains the advantage of said "round” thanks to its empty central zone.
  • the cushion according to the invention offers the advantages of so-called alternative mattresses (alternative compression-decompression) while eliminating the drawback of these mattresses, namely contact with bedsores, persistence of compression relative to this place and the absence or lack of ventilation of the wound.
  • alternative mattresses alternative compression-decompression
  • the air forced into the recess remedies the maceration of pressure ulcer wounds.
