Definitions
- the invention relates to a breathing apparatus with a protective hood with a breathing connection ending inside in the form of a half mask and carrying a replaceable breathing filter on the outside.
- Respirators with a protective hood according to the invention can be found as rescue devices, e.g. as escape devices, use .. To do this, they must be available in a functionally reliable manner, put on by inexperienced people, and then used breathing filters can also be replaced by these users after a long period of use.
- a respirator with protective hood has become known, 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 also unfolds when the protective hood is unfolded bag is opened on both sides. 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.
- the E-PS 650 830 describes an oxygen breathing apparatus, in which an an oxygen-releasing, carbonic acid-binding mass containing cartridge can be replaced during use of the device.
- 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 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 catastrophe, in such a way that the breathing filter can be easily used by them or replaced after use.
- the breath connection has a plug-in frame which is open on opposite sides and in which the breathing filter to be inserted, which is sealed on both sides by seals and is ventilated by its input walls, is accommodated.
- the insert frame can carry a dust filter on the outside in front of the breathing filter.
- 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 breathing filter has a cutting edge with which it is also in the packaging bag after it has been put on Lichen holding collar on the insertion frame cuts open the packaging bag, this process of inserting it into the insertion frame is immediately connected to the removal from the packaging bag.
- the breathing apparatus consists of a breathing connection 1, tightly inserted in a protective hood 2.
- the breathing connection 1 ends in the inside of the mask in a half mask 3. It is designed on the outside in a cassette-like manner 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.
