Definitions

  • the present invention relates to portable hyperbaric chambers, provided with an auxiliary compartment, intended for the transport and first aid of a victim of a decompression accident.
  • the technical sector of the invention is that of the construction of rescue equipment for divers victims of decompression sicknesses.
  • hyperbaric chambers which are fixed chambers permanently located in hospitals or in rescue centers for victims of too rapid decompression sicknesses.
  • German document DE-A-1 506 787 describes a diving bell intended to be immersed in depth and then brought outside on land or on a boat.
  • a single-seater box is adapted in a manner as described in the preamble of claim 1 of the present invention to thus introduce personnel into the bell without the latter being brought back to ambient pressure.
  • British patent 294,749 describes a hyperbaric chamber intended for transferring divers from the workplace to a rest chamber maintained at the same pressure or to another chamber.
  • the objective of the present invention is to provide such a hyperbaric chamber, light and compact, which can be brought quickly to the scene of an accident, so that a diver victim of a decompression accident is placed quickly in the lying position in the caisson, under a pressurized atmosphere and can thus be easily transported to a rescue center while being accompanied by a trainer who can assist the accident victim throughout the journey, and as is done in the caissons multiplace.
  • a transportable hyperbaric chamber a single-seat box capable of receiving a lying victim and an auxiliary compartment intended for a healer, which auxiliary compartment has a single opening which is closed by one end of the single-seat box. , which end is assembled at the opening by a removable and watertight fixing, said single-seater box has an access which is closed in a leaktight manner by a removable shutter pad and which is located at the end of the single-sided box which is assembled with the compartment auxiliary, characterized in that said shutter pad is located inside the auxiliary compartment when the single-seat box is assembled with the auxiliary compartment and the single-seat box serves as a door for closing the opening.
  • the single-seat box has the general shape of a cylindrical enclosure which has two axially opposite ends, a first end which is closed by a curved bottom welded to the side walls of the enclosure and a second end which comprises at its internal periphery a bayonet socket into which engages the edge of the shutter plug for access to the single-seat box and which further comprises, at its external periphery, a crenellated flange which engages in a bayonet socket located at the periphery of the access opening of the auxiliary compartment.
  • the single-seat box comprises two coaxial cylindrical ferrules, of different diameter
  • the ferrule of larger diameter comprises at one of its ends the access to the box and at the other end it comprises, at its internal periphery, a socket with bayonet in which engages a crenellated flange located at the external periphery of one end of the ferrule of smaller diameter
  • the sleeve being provided at its external periphery with a crenelated flange intended to engage in a bayonet sleeve to assemble the larger diameter ferrule with a box.
  • the invention relates to a new portable and space-saving hyperbaric chamber intended for the transport of divers victims of a decompression accident to a rescue center comprising a fixed and multiplace hyperbaric chamber.
  • An advantage of the box according to the invention lies in the fact that the single-seat box containing the accident victim can be temporarily dissociated from the auxiliary compartment containing the attendant so that a single-seat box made of an aluminum alloy or any other metal or light alloy resistant to a pressure of 5 bars, with the accident it contains, reaches a total weight of around 150 kg to 200 kg and can be transported by four people.
  • the internal walls of the single-seater box can be fitted with slides on which the stretcher or berth supporting the accident victim is placed and the trainer can pull the latter towards him and have better access to the accident's upper airways.
  • the attendant Upon arrival at the rescue center, the attendant closes the shutter pad.
  • the entire device including the single-seater box, the auxiliary compartment, an accident victim and an attendant, weighs around 300 to 350 kg and can be carried by six or seven men.
  • FIGS. 1, 2 and 3 represent a hyperbaric chamber intended for the transport of a victim of a decompression accident to a treatment center comprising a fixed multiplace hyperbaric chamber.
  • the box according to the invention comprises, on the one hand, a single-seat box 1 which can contain a single accident 2 lying on a stretcher or a berth 3 placed on side rails 4. It comprises, on the other hand, an auxiliary compartment 5 or airlock which may contain a companion 6 seated on a seat 7, which companion can give care to the accident victim during transport.
  • the two compartments 1 and 5 can be pressurized for example to 5 or 10 bars and they are constructed to withstand this pressure.
  • they are constructed of metal or of a light alloy having good mechanical properties, for example of aluminum and magnesium alloy.
  • the means for pressurizing the two compartments for example compressed air bottles which are connected to orifices provided with valves, are not part of the invention and are not shown.
  • the auxiliary compartment 5 has a window 8 and a single access opening 9 through which the attendant 6 enters and leaves the compartment.
  • the single-seater box has the general shape of an elongated cylindrical enclosure 1, of axis x x1, the total overall length of which is approximately 2 m so that a man can be placed there in the extended position.
  • the feet of the victim are placed towards the end which is furthest from the auxiliary compartment and this end is closed by a sheet metal bottom 10 which is welded to the side walls of the enclosure.
  • the other end of the enclosure 1 has an access opening which is closed by a removable obturator pad 11, which comprises for example a crenellated peripheral flange 12 which engages in a bayonet socket 13 situated at the internal periphery of access opening.
  • Figure 5 shows on a larger scale the detail of the assembly of the shutter pad 11 in the bayonet socket 13.
  • An O-ring 14 placed in a groove cooperates with the non-crenellated part of the flange 12 to seal the assembly.
  • the pad 11 has handles 15 which allow it to be inserted into the bayonet socket and to be rotated to engage the slots of the flange through the notches of the socket and then behind the locking notches of the latter.
  • the end of the single-seat box which is closed by the obturator pad 11 is that where the patient's head 2 is located, which is engaged in the box 1, the feet towards the bottom 10.
  • the end closed by the pad 11 is assembled in the opening 9 for access to the compartment and serves as a door for closing this opening.
  • the assembly between the box 1 and the compartment 5 is carried out by means of a removable and waterproof fixing.
  • the opening 9 has at its external periphery a crenellated flange 17 which engages in the socket 16 to carry out this assembly.
  • An O-ring 18, placed in a groove cooperates with the non-crenellated part of the flange 17 to seal the assembly.
  • the guide replaces the shutter pad 11, so that the single-seater box is isolated from compartment 5 and can then be disassembled from it and transported separately.
  • the total weight of the single-seater box containing an accident victim is around 150 to 200 kg for an aluminum alloy box resistant to an internal pressure of 5 bars and this box can therefore be easily transported by four men, to go by example of an ambulance or helicopter with a fixed multi-seat hyperbaric chamber.
  • the single-seater box 1 is composed of two separable parts, for example two coaxial ferrules, a ferrule 1a located on the side of the head and a ferrule 1b whose diameter is smaller than that of the ferrule 1a and which is closed by the bottom welded 10.
  • the ferrule 1a has at its end placed on the side of the ferrule 1 a conical reduction 1c which makes it possible to make up for the difference in diameter.
  • Figure 4 shows the assembly of the shell 1b on the shell 1a on a larger scale.
  • the conical reduction 1c has at its end a bayonet socket 19.
  • the ferrule 1b has at the outer periphery of its end opposite the welded bottom 10, a crenellated flange 20 which engages in the socket 19 to produce a removable assembly.
  • FIG. 4 shows a partial section of a hyperbaric chamber 22 which is a multiplace prolonged treatment chamber permanently located in a rescue center or a hospital.
  • the access opening of this box comprises a bayonet socket 23.
  • the bayonet socket 19 has at its outer periphery a crenellated flange 24 which engages in the bayonet socket 23 to assemble the ferrule 1 a with the box 22.
  • the one-piece box 1 has a small airlock 26 which allows objects or medicines to be introduced into box 1 without decompressing it.
  • the interior door of this airlock is located near the shutter pad 11 so that it can be handled by the attendant 6.
  • the box 1 also includes a porthole 27.
  • the ferrule 1a of the monobloc box is surrounded by a tubular structure 28 which protects it from shocks and which is extended, on each side, by a handle 29a, 29b used to transport the monobloc box.
  • a handle 30 is fixed to the welded bottom 10.
  • the auxiliary compartment 5 is placed on a tubular frame 31 which is provided with two hand carrying handles 32a and 32b.
  • the one-piece box 1 is assembled to the frame only by its end provided with the buffer 11, so that it is in a console above the frame 31, which makes it possible to engage the ferrule 1 b in a fixed box 22, without be hindered by the frame 31.
  • the auxiliary compartment has on its side walls handles 33a and 33b.
  • six or seven men can transport the assembly formed by the monobloc box 1, by the auxiliary compartment 5 and by the frame 31 by gripping it by the handles 33a, 33b, 29b, 32a, 32b and 30.
