Definitions

  • the present invention relates to an intermediate connector for a breathing apparatus nozzle.
  • these fittings are screw fittings, the female socket of which is carried by the mask while the male socket is carried by the air supply device.
  • one of the sockets has spouts capable of engaging behind the stop face of a lip complementary to these spouts carried by the other socket.
  • the spouts are movable perpendicular to the axis of the fitting either by the effect of a pressure directly exerted on them or by means of buttons accessible from the outside, so as to allow the latching and unclipping of the fitting.
  • Such connections are for example described in patent FR-2,537,695.
  • Some of the air supply devices are connected to a source of pressurized breathing air and a slight overpressure is provided inside the mask so as to avoid the penetration of toxic gases possibly present outside.
  • a slight overpressure is provided inside the mask so as to avoid the penetration of toxic gases possibly present outside.
  • the movable probe parallel to the axis of the tip is free or depressed depending on whether the tip is disassembled or mounted on the mask.
  • the end piece of the respiratory device is not directly fixed on the mask but by an intermediate connector.
  • the objective of the invention is to solve this problem by proposing an intermediate connector which allows the connection between a snap-on end fitting comprising a feeler and a female screw socket while ensuring proper operation of the feeler.
  • an intermediate connector for the end piece of a breathing apparatus intended to allow the connection between a snap-on end piece comprising a movable feeler parallel to the axis of the end piece and a first screw socket of the type comprising a body provided at one of its ends of a snap-on socket complementary to that of the end piece and at the other end of a second screw socket intended to cooperate with the first screw socket.
  • this intermediate connection comprises an inner ring movable in translation parallel to the connection axis between two extreme positions. The probe is actuated by the inner ring only when the connection is completely and correctly made.
  • the intermediate connector 1 intervenes in the connection between the mask 2 and the snap-on endpiece 3 of the respiratory system.
  • the mask 2 is generally provided with a female screw socket 4.
  • the snap-on end piece 3 comprises a probe 31 movable parallel to the axis 5 of the end piece 3.
  • This probe 31 is held in position when it is free, by a spring 32. When it is in this free position, it controls the shutdown of the air supply to the respiratory system. When under the effect of an external action the feeler is pressed against the spring 32, it controls the supply of pressurized air into the nozzle of the respiratory system.
  • the respiratory system and the mask 2 can have various origins, so it is often difficult to provide for direct adaptation of one to the other.
  • the intermediate connector of the invention allows this adaptation and ensures the operation of the probe 31.
  • the connector 1 comprises a body 11 provided at one of its ends with a snap-on socket 12 intended to cooperate with the socket 33 of the nozzle 3 of the air supply and at its other end a male screw socket 13 intended to cooperate with the female screw socket 4.
  • the female screw socket 4 is either directly carried on the mask or carried by an additional element fixed on the mask. In the latter case, this additional element is firmly fixed on the mask so that it does not risk being dismantled during the practical use of the mask. These two configurations are therefore analogous.
  • the female screw socket can be assumed to be worn by the mask.
  • the sealing of the snap-on socket is carried out by the O-ring 15 and the sealing of the screw socket by the seal 16 placed in abutment on a shoulder 41 of the female part of the screw socket and on which comes to bear. the end of the male socket 13.
  • the intermediate connector 1 has an inner ring 14 movable relative to the body 11 parallel to the axis of the connection 5.
  • the body 11 of the intermediate connector 1 has an internal stop 111.
  • This stop 111 cooperates with two external shoulders 141, 142 of the inner ring 14. They are each located on one side of the stop 111 and therefore limit the movements of the ring 14.
  • a spring device 5 recalls the inner ring 14 in its rest position in which the shoulder 141 is in support on the stop 111 when the inner ring is free, that is to say that it is not subjected to any external action.
  • the configuration of the body 11 is determined relative to that of the end piece 3 of the air supply so that, in the absence of an inner ring 14, no element of the body 11 can be present facing the movable probe 31 against by the inner ring 14 has a configuration which allows it to act on the probe 31 when it is in the active position and to release it when it is in the rest position.
  • the internal radius of the body 11 is greater than the distance from the probe 31 to the axis 5 so that it is inside the body 11.
  • the inner radius of the ring 14 is less than this same distance from the probe 31 to the axis 5.
  • the stroke of the inner ring in its movement parallel to the axis 5 inside the body 11 is such that when the snap-in sleeve is closed, the inner ring presses on the probe when it is close to it and releases it when it is far away.
  • the inner ring 14 has a flat surface in the shape of a crown towards the feeler which enables it to fulfill its function whatever its angular position around the axis 5.
  • the snap-on socket 3, 12 When the snap-on socket 3, 12 is closed, two situations are possible. If the screw socket 4, 13 is open, the intermediate ring 14 is held by the spring 6 in its free position and the probe 31 has enough space inside the body 11 to remain itself in the free position . If, on the contrary, the screw socket 4, 13 is closed, the inner ring 14 being, as we have seen, moved against the spring 5, is brought closer to the nozzle 3 of the respiratory system. It exerts pressure via its face 143 on the probe 31, moves it against the spring 32 in its depressed position in which it controls the supply of air to the respiratory system.
  • the air supply to the respiratory system is only controlled by the movable probe 31 when simultaneously the snap-on socket 3, 12 and the screw socket 4, 13 are closed. that is to say when the connection between the snap-on end piece 3 and the screw socket 4 is suitably and completely made.
  • the body 11 comprises a skirt 112 which covers the screw socket when the latter is closed. This prevents the screw socket from being subjected directly to difficult external conditions, for example splashing liquids.
  • the body 11 has perforations 113 which allow liquids which could have accumulated between the skirt 112 and the female screw socket 4, either by condensation or following projections, to flow and not not stay in the vicinity of the screw socket.
  • At least one of the shoulders of the ring 14 is elastically deformable so as to allow the positioning of the ring 14 in the body 11.
  • the spring device 5 consists of a coil spring surrounding the ring 14 and placed during the mounting of the ring 14 inside the body 11 bearing on the one hand on the stop 111 and on the other hand part on the shoulder 142.
  • a housing can be provided inside the shoulder 142 in which the coil spring partially engages.
  • the intermediate connector of the invention therefore ensures a reliable connection between a mask and a respiratory device while allowing the use for all desired purposes of a movable probe parallel to the axis of the nozzle and detecting closure of the junction.
  • This intermediate connection makes it possible to associate a breathing apparatus and a mask of different origins.
