Definitions

  • the invention relates to a dual compartment bag for use as an artificial lung.
  • exhaled breath still contains sufficient oxygen to allow a person to breathe in and out few times using the same breath. It could therefore be of vital importance to enable a person to breath his own breath via an artificial lung in case of an emergency situation e.g in case of fire or when he is cast in the sea.
  • a dual compartment bag for use as an artificial lung comprises: - a breathing compartment, which is fitted with a mouthpiece so as to allow a person carrying the bag to breathe in and out using the same breath, - a buoyancy compartment which is inflatable with a gas, and - means for securing the bag below the wearers neck in a central position in front of the wearers body.
  • the buoyancy compartment at least partly surrounds the breathing compartment so that the buoyancy compartment forms a protective cage around the breathing compartment.
  • the means for securing the bag below the wearers neck are formed by a non inflatable collar which can be pulled around the wearers neck and a clip for securing the lower end of the bag to the clothes in the region of the wearers crotch.
  • the bag remains central along a line from the chin to the crotch upon inflation of the buoyancy compartment.
  • the central positioning of the bag in front of the body is an essential part of the bags function in creating a turning moment to bring the wearer into the face up position upon immersion.
  • FIG. 1 there is shown a person wearing an inflatable overall immersion suit 1 to which a dual compartment bag 2 according to the invention is secured.
  • the bag 2 is equipped with a non-inflating collar 3 which is pulled around the neck of the wearer and a clip 4.
  • the clip 4 is locked to an eye 5 which is secured to the suit 1 in the region of the crotch.
  • the collar 3 and clip 4 enable a quick attachment of the bag 2 to the suit in such a manner that the bag 2 is maintained in a central position in front of the body of the wearer.
  • the bag 2 comprises a buoyancy compartment 7 and a breathing compartment 8.
  • the buoyancy compartment at least partly surrounds the breathing compartment 8 and thereby protects the fragile wall 10 of the breathing compartment 8.
  • the buoyancy compartment 7 is provided with a so-called Roberts valve 11 which can be used to actuate a CO2 cartridge (not shown) to inflate the buoyancy compartment with CO2.
  • the breathing compartment 8 is connected via a flexible hose 12 to a mouthpiece 13.
  • the hose 12 is secured to the bag 2 by a base ring 14 which simultaneously serves to anchor the wall 10 of the breathing compartment to the bag 2 of the buoyancy compartment 7.
  • the bag 2 has an elongate box-like mid portion and tapered end portions to which the collar 3 and clip 4 are secured.
  • the operation of the dual compartment bag is as follows. During normal travelling circumstances the un-inflated bag 2 is attached by the collar 13 and clip 4 to an inflatable immersion suit 1 of e.g. a helicopter passenger. However, when the wearer is cast in the sea following an accident, he will use the breathing section of the dual compartment bag whilst underwater.
  • an inflatable immersion suit 1 e.g. a helicopter passenger
  • the wearer By subsequently exhaling and inhaling his own breath again several times via the mouthpiece and the artificial lung provided by the breathing compartment 8 the wearer is able to breathe while he is escaping to the water surface. Once the survivor reaches the surface he may inflate the buoyancy compartment of the bag by means of the Roberts valve 11, to ensure that he floats with his head clear of the water in an upright position.
  • the breathing compartment 8 can be fitted with a dual hose having non-return valves which are set in opposite directions. If the wearer breathes out through the mouthpiece his breath circulates through the hose and breathing compartment 8 rather than the pendulum action described above.
  • the buoyancy compartment may upon immersion be automatically inflated with any suitable gas instead of filling this compartment with CO2 by actuating the Roberts valve. Accordingly it is to be understood that the foregoing description with reference to the accompanying drawings is illustrative only.
