Definitions

  • the present invention relates to a breathing apparatus according to the preamble of claim 1.
  • the breathing bag worn in front of the chest can reach temperatures in the course of ventilation as a result of the released heat of reaction of the oxygen-developing chemical, which leads to a heat build-up between the breathing bag and the chest area, which can cause skin irritation or reddening on the device wearer.
  • the invention is therefore based on the object of creating a breathing bag which lowers the contact temperature between the breathing bag and the chest area of the device wearer using simple and space-saving means.
  • the advantages achieved by the invention are in particular that the special design and arrangement of the hollow body on the breathing bag ensures optimal heat dissipation between the breathing bag and the chest area of the device wearer.
  • an oxygen-evolving chemical cartridge 2 to which a breathing tube 3 is connected, is arranged inside a breathing bag 1.
  • the end of the breathing tube is provided with a mouthpiece, not shown in the drawing.
  • a heat formed as a hollow body 4 protection attached On the side of the breathing bag facing the device carrier is a heat formed as a hollow body 4 protection attached. The attachment takes place via two webs 5 which are arranged on the hollow body 4 and are led out laterally and which can be inserted into tabs 6 which are appropriately designed and attached to the breathing bag 1.
  • the tabs 6 are made of the same material as the breathing bag 1.
  • the hollow body 4 consists of a compressible material with low thermal conductivity, preferably made of silicone elastomers.
  • the hollow body 4 is cuboid and has thin-walled ribs 7 which are arranged at a distance from one another and divide the hollow body 4 into chambers (FIG. 2). These chambers serve as air channels A, the so-called. The cooler ambient air can flow through the chimney.
  • the contact surface B of the hollow body 4 is enlarged on the body side of the device carrier with respect to the contact surface C on the breathing bag 1 by a flap part 8 which projects somewhat beyond the upper edge of the breathing bag and covers it. This measure deflects the heat flow from the chin area of the device carrier.
