Definitions

  • the invention relates to a breathing apparatus with a protective hood according to the first part of claim 1.
  • Such a breathing apparatus with protective hood is already known from DE-C-650 830.
  • Respirators with a protective hood according to the invention can be found as rescue devices, e.g. as escape devices, use. If necessary, they must both be available in a functionally reliable manner and be able to be put on by inexperienced users. Furthermore, if the filter is used for a longer period of time, it must be possible for users to replace it.
  • a respirator with a protective hood which is intended as a filter device with a half mask for escape purposes.
  • the filter is sealed against environmental influences in a packaging bag and tightly integrated with it into the half mask and the protective hood surrounding it by means of a clamp.
  • the ends of the packaging bag are divided by tear lines and connected to the folded protective hood so that when the device is started up, the packaging bag is opened on both sides at the same time as the protective hood is unfolded. Due to the difficult clamp attachment, the used filter cannot be replaced by laypersons either to extend the readiness for use during the preparation, after exercises or during use to extend the service life.
  • DE-C-650 830 describes an oxygen respirator in which a cartridge containing an oxygen-emitting, carbon-binding mass can be replaced while the device is in use.
  • the mask has a connector into which a tubular container is screwed by means of a screw connection. This is open on both sides and has openings opposite one another in its jacket. One opening creates the connection to the inside of the mask through the screw connection, while the other opening leads to the exhalation tube and above it to the breathing bag.
  • the cartridge to be inserted from the side into the tubular container has openings in its jacket which coincide with the openings in the container. If the cartridge is used up, it can be replaced by a new cartridge when the respirator is in use.
  • the object of the invention is to improve a breathing apparatus with a protective hood, which can be easily put on even by inexperienced people in the event of a disaster, in such a way that the breathing filter can be easily used by them or replaced after use.
  • the breathing connection ends in the form of a half mask in the interior of the hood and in that the breathing filter has a cutting edge with which a packaging bag surrounding the breathing filter can be separated by placing a retaining collar attached to the packaging bag on one of the open ones On the side of the insertion frame, the part of the packaging bag which is enclosed by the holding collar is pierced by inserting the breathing filter into the insertion frame.
  • the advantages achieved by the invention consist in particular in that, by simply inserting the breathing filter into the plug-in frame without complications, even inexperienced persons, especially in the event of a catastrophe, always have reliable protection.
  • the used respiratory filter can be replaced without interrupting the respiratory protection.
  • the exercise can be practiced with directly provided exercise filters. It is good if the user has noticed the breathing resistance, which unfortunately cannot be completely avoided.
  • the insertion frame carries a dust filter on the side facing away from the hood.
  • the respirator consists of a breathing connection 1, tightly inserted into a protective hood 2.
  • the breathing connection 1 ends in the inside of the mask in a half mask 3. It is designed in the manner of a cassette on the outside in such a way that it ends in a plug-in frame 4 which is open at the top and bottom and into which the desired breathing filter 5 is inserted.
  • the seals 6 seal the breathing filter 5 directly from a lateral air passage.
  • a dust filter 7 protects against ambient dust when breathing.
  • the breathing filter 5 is ventilated directly through its input walls 8.
  • the used breathing filter is replaced by inserting a replacement filter 12, which had been securely packaged until then.
  • FIG. 2 shows the respiratory filter 5 in a packaging bag 9. It has a cutting edge 10.
  • the packaging bag 9 additionally contains a holding collar 11 which fits on the plug-in frame 4.
  • the cutting edge 10 simultaneously cuts open the packaging bag 9.
