Definitions

  • the invention relates to a gas-tight protective suit with a chemical oxygen respirator to be worn under the protective suit according to the preamble of claim 1.
  • a hose connection element is arranged between a pressure relief valve of a breathing bag of the breathing apparatus and a valve defined in the protective suit, through which an overproduction of oxygen accumulated in the breathing bag can be derived from the protective suit (FR -A-2314735).
  • the invention is therefore based on the object of ensuring a safe discharge of the excess oxygen from the protective suit to the outside in a chemical oxygen device to be worn under a gas-tight protective suit.
  • a flexible hose connection element 5 is arranged between the pressure relief valve 1 of the breathing bag 2 and an exhalation valve 3 of the protective suit 4, by means of which an overproduction of oxygen accumulated in the breathing bag is blown out of the protective suit into the open air .
  • the hose connection element 5 consists essentially of a flexible hose part 6, each with fixedly arranged screw connection parts 7 at the free ends, which are provided for captive connection on the one hand to the valve holder 3a of the exhalation valve 3 in the protective suit 4 and on the other hand to a connecting piece 8, which in a Pressure valve 1 comprising elastic cap part 9 is inserted or buttoned.
  • the hose connecting element 5 with the connecting part 8 is at this end on the pressure relief valve 1 detachably fixed, while it is screwed firmly at the other end to the valve holder 3a of the exhalation valve 3 in the protective suit 4.
  • the elastic cap valve 9 is in the form of a bellows-type rubber cap 9a.
  • the cap part 9 arranged on the pressure relief valve 1 and on the outside of the breathing bag 2 can be folded because of its bellows-like design, which is also advantageous for the desired tight packing of the chemical oxygen device 12 into a container when the device is stored.
  • the cap part 9 also serves as a protective cap for the pressure relief valve 1.
  • a ring 9b protruding beyond the bellows 9a is formed, the inside diameter of which is designed as a holding bead 9b which engages in a groove 8a in the connecting piece 8 of the hose connecting element 5 which corresponds to the holding bead when the hose connecting element is inserted or buttoned into the cap part 9 becomes.
  • the seal between the cap part 9 and the connecting piece 8 takes place at a point 9d inside the cap part 9, while the retaining bead 9b is fixed by a so-called tight fit in the groove 8a of the connecting piece 8. A secure fit of the connecting piece 8 in the cap part 9 is thereby achieved.
  • the ring 9b is designed as a grip part for inserting or removing the connecting piece 8.
  • the cap part 9 is fixed on the valve holder 1 a of the pressure relief valve 1 and clamped with it on the fabric edge 2 a of the breathing bag 2.
  • the pressure relief valve 1 opens by means of a pull chain 10 arranged in the breathing bag 2 and the oxygen blown out of the breathing bag passes in the direction of arrow A via the hose connection element 5 and the exhalation valve 3 outside the protective suit 4 , wherein the exhalation valve is covered by a protective cap 11, which deflects the oxygen flow, for example downwards towards the floor.
  • the device carrier carries the chemical oxygen device 12 in front of the chest under the protective suit 4 and the hose connecting element 5 according to the invention deflects the excess oxygen accumulated in the breathing bag 2 through the protective cap 11 to the outside.
