Definitions

  • the invention relates to an emergency respirator, according to the preamble of claim 1.
  • both the 0 2 supply can fail and additional hypothermia can occur through breathing. This difficult situation should be avoided as simply and safely as possible.
  • the breathing device consists of a pack of metal sieves which are arranged in a housing made of poorly heat-conducting material on a breathing mask. Breathing takes place in the pendulum mode. The body heat transported with the exhaled air is stored in the metal sieves and then returned to the mask wearer with the inhaled air.
  • This breathing device can only be used in environments that contain air that is otherwise breathable, regardless of temperature conditions. Compensation for a lack of oxygen is not possible (GB-PS-416 409).
  • DE-B-1 259 207 describes a breathing apparatus with pendulum breathing, which has a heat exchanger between the mouthpiece and the chemical cartridge for the regeneration of the breathing air to cool the heated inhaled air.
  • the object of the invention is a simple emergency respirator that supplies the wearer with breathable inhalation air in the event of a failure of the supply systems and also prevents heat losses through breathing.
  • the main advantages of the emergency respirator can be seen in the double effect, namely the 0 2 supply for the wearer and the use of the heat of reaction from the cartridge to prevent the cooling of the respiratory organs of the wearer. This is done in a device that is safe and easy for the user.
  • the necessary amount of oxygen is released into the immediate vicinity when exhaling and then breathed in again with the next breath.
  • the amount of heat stored in the heat storage from the exhaled air is removed with the next inhalation and returned to the device carrier.
  • the construction of the device is very simple, since a breathing bag is not required.
  • the additional external heat insulation around the cartridge casing at the level of the heat store supports the heat-storing effect in a simple manner.
  • the breathing apparatus contains a C0 2 -binding and thereby 0 2 -generating cartridge 1 with a known internal structure, to which a mouthpiece 3 with a nose clip 4 is connected via a folding tube 2.
  • the cartridge 1 has on its bottom 5, held by the cartridge casing 6, a heat store 7.
  • the material of the heat store.7 is a highly porous Al cylinder.
  • the emergency respirator is protected at the mouthpiece 3 by a stopper 8 and at the end of the cartridge casing 6 by a tear-off cover 9 from the ingress of moisture during the rest period.
  • the device When the emergency situation arises, the device is opened by removing the stopper 8 and the cover 9 and can then be ventilated. Ventilation is based on the pendulum principle. During exhalation, the C0 2 is bound in the cartridge 1 from the exhaled air and 0 2 and at the same time heat is generated. The generated heat is stored in the heat accumulator 7 as it flows through during the exhalation phase, in order to then flow into the inhalation air while it is heated.
  • the user of the emergency respiratory protection device is thus supplied with 0 2 and at the same time protected against excessive cooling, since he absorbs the previous heat of reaction with the inhalation flow.

Claims (3)

1. Appareil respiratoire d'urgence, qui peut être utilisé pour la respiration d'une manière pendulaire dans un environnement présentant des températures d'air défavorables pour l'inspiration, et qui contient une cartouche (1.) fixant le C02 et produisant ainsi de l'oxygène, avec un embout buccal (3) qui lui est relié par l'intermédiaire d'un flexbile à soufflet (2), caractérisé par un accumulateur de chaleur (7) disposé sur le fond (5) de la cartouche (1) en amont de la cartouche (1) dans le sens d'inspiration, et maintenu par l'enveloppe (6) de la cartouche.
2. Appareil respiratoire d'urgence selon la revendication 1, caractérisé en ce que l'accumulateur de chaleur (7) est un cylindre d'aluminium très poreux.
3. Appareil respiratoire d'urgence selon la revendication 1 ou 2, caractérisé en ce que l'enveloppe (6) de la cartouche est munie extérieurement, à hauteur de l'accumulateur de chaleur (7), d'une isolation (10).
