Definitions

  • the present invention relates to a mountable and removable connection nozzle for insulating breathing apparatus in open circuit, belonging to the device for connecting the mask to a bottle of pressurized breathing gas.
  • connection devices include one or two stage regulators, and, in the case of two stage regulators, the second is fixed to the mask. This second stage is then integrated into a connection endpiece which is either fixed on the snout of the mask, or more generally mountable and dismountable on it.
  • assembly and disassembly can be carried out for example by screwing (and unscrewing) or by interlocking.
  • the operation is provided under overpressure, so as to avoid the introduction of toxic gas inside the mask.
  • connection devices have been designed which allow manual operation to pass first through an operating phase under vacuum, then to the operating phase under overpressure.
  • connection end piece mountable and dismountable on the snout of a respiratory mask, said nozzle having an interior chamber adapted to communicate with the mask in the mounting position, a connection tube to a source of pressurized respiratory gas, a valve to allow or prevent the flow of gas under pressure, a manometric means sensitive to the relative pressure prevailing inside the chamber, and means for controlling said valve by manometric means, endpiece characterized in that it comprises a free or depressed probe according to whether the endpiece is mounted or dismounted on the mask, this probe being associated with the servo means by means of modifiers of the operating regime, which modifying means are adapted to establish an operating regime in vacuum or an operating regime in overpressure depending on whether the probe is in the free or depressed position.
  • the endpiece has a device making it possible to be automatically in depression when it is not connected to the mask and in overpressure from the connection, makes it possible to avoid all the drawbacks mentioned above.
  • the end piece 1 which can be mounted and dismounted on the snout 3 of a respiratory mask, comprises an interior chamber 11 adapted to communicate with the mask in the mounting position, a 'connection tube 12 to a source of pressurized breathing gas (not shown), a valve 13 to allow or prohibit the flow of gas under pressure, a gauge membrane 14 sensitive to the relative pressure inside the chamber 11, and means for controlling the valve 13 to the pressure gauge.
  • these control means consist of a lever 15 slightly inclined relative to the longitudinal axis of the valve 13 and fixed to it, and a rod 16 fixed to the membrane 14 and standing in the chamber 11 perpendicular to this membrane, the lever 15 and the rod 16 being secured so that a depression in the chamber 11 causes the valve 13 to move away from its seat 131 despite the action of a return spring 132, at least in a region of the contact surface between these two members 13, 131.
  • the end piece 1 comprises a probe 17 protruding outside the chamber 11 and movable in translation between a "free” rest position which it occupies when the end piece is not connected to the snout 3, and a "pushed in” position when the tip is connected to the snout;
  • this probe 17 is associated with the control means by means of modifiers of the operating regime, which are adapted to establish an operating regime in depression or in overpressure depending on whether the probe 17 is respectively in the free or depressed position.
  • the modifying means comprise a bent spring 18, with two branches, consisting of a metal wire of the piano string type, mounted pivoting around a central axis 181 carried by a plate 19 passing through the chamber 11 substantially parallel to the position occupied by the lever 15 when the valve 13 is applied to its seat.
  • the spring 18 is positioned so that, on the one hand, one of its branches is near the end of the probe opposite to that in prominence of the chamber, when it is in the "free” position, and that the other branch is then near the lever 15 for actuating the valve, and on the other hand that the first branch is pushed by the end of the feeler in the "depressed” position, the second branch then pushing the lever 15 laterally to move the valve away from its seat over part of the contact surface of these two members.
  • the plate 19 can also carry abutment members to limit the stroke of the first branch of the spring 18 during its tilting around the pivot axis 181 under the action of the feeler 17; it is, of course, provided with an opening 191 for the passage of the rod 16 and possibly for a distribution of the pressures on both sides, this distribution being able to be ensured by the fact that the opening 191 has a substantially cross section greater than that of the rod 16, or / and by additional openings (not shown in Figures 1 and 2).
  • the plate 19 also comprises, in the region of the pressure distribution opening, a deflecting tab 192 intended to channel the air leaving the valve and to cause a Venturi effect to temporarily create a depression near the membrane 14 when this is necessary, as will be seen later.
  • the end piece 1 also includes a direct passage pusher 21 provided for manually actuating the membrane 14 and consequently the control means 15, 16 in the direction of opening of the valve 13 if necessary.
  • the probe 17 is mounted movable in translation in a support barrel 22 intended to penetrate into a receptacle piece 31 provided in the snout 3 of the mask, more specifically inside a fixing ring 32.
  • the receptacle 31 comprises a front abutment shoulder 311 intended, when the end piece is mounted on the snout, to cause the depression of the probe 17; to seal the connection, an O-ring 312 is provided inside the receptacle 31.
  • an interlocking member 23 constituted in the form of an elastic collar with levers provided with an external peripheral lip 231 intended to be housed in a groove annular 313 produced in the receptacle 31 to maintain the fitting 1 in the snout 3 of the mask in the fitting position by fitting.
  • the valve 13 is kept applied against its seat by the spring 132 and the overpressure in the connection tube 12, and the end piece does not deliver respiratory gas. Only a vacuum in the chamber 11, or an action on the direct passage pusher 21, causes the lever 15 to tilt and, consequently, the valve 13 to open, the spring 18 being out of contact with the lever 15 -due that the probe 17 is in the free position. It is therefore a regime of operating in depression.
  • the feeler 17 goes into the depressed position, and causes the spring 18 which actuates the lever 15 to tilt, which causes the valve 13 to open; the action of the spring 18 is then compensated by the overpressure which is exerted on the membrane 14, which closes the valve 13, which does not open again until the overpressure tends to decrease during an inspiration.
  • the structure and the arrangement of the nozzle allow that, during a violent inspiration of User, there exists under the membrane a sufficient depression to maintain the opening of the valve 13 and, consequently, a very slight overpressure in the mouthpiece and in the mask, even preventing in this case the introduction of harmful ambient gas against which the respiratory system is intended to protect itself. There is therefore then permanently overpressure operation.
  • the nozzle can operate as a permanent vacuum valve, or as a screw-in valve, by simple modification of some of the parts making it up (the probe 17 in the first case, the member 'nesting 23 in the second).
  • the tip 1 comprises a micro-regulator of a known type housed in a housing 10 the upper part of which has been shown torn off, comprising, in communication with the connection tube 12 to the source of respiratory gas, a respiratory gas intake channel whose external walls constitute the seat of a valve (not visible on the Figures 3 to 5) produced in the form of a flexible diaphragm short-circuited by a calibrated nozzle; the surface of the diaphragm delimited by the intake channel on the side of this channel being smaller than on the other side, the diaphragm is therefore normally in abutment against its seat.
  • the side of the diaphragm opposite the intake channel defines a chamber where the calibrated nozzle opens; in this chamber, also opens a control nozzle 41 communicating on the one hand with a control chamber 42 and, on the other hand, with the outside by a channel 43;
  • this control chamber 42 comprises on one side the manometric control membrane 14, subjected on the side opposite to the control chamber 42 to the action of a return spring 45 placed in an internal control chamber 46 in communication with the inside of the mask snout; the manometric control membrane 44 is normally pushed by the return spring 45 so as to close off the servo-jet 41;
  • a communication tube 47 connects the space surrounding the intake channel, also inside the snout of the mask, all of the cavities in direct communication with the snout constituting the chamber 11.
  • the modifying return means of the operating regime also include a lever 51 bearing against a shoulder 52 produced on the outer wall of the control chamber 46, this lever being actuated at one of its ends by the feeler 17 and actuating at its other end, produced in the form of a fork, a slider 53 interposed between the return spring 45 and the additional spring 50, by means of außnse54 rod connecting the two branches of the fork and secured to this cursor 53; in practical terms, the movement of the wandering rod is allowed by slides made in the walls of the chamber 46.
  • the return spring 45 and the additional spring 50 are placed in series between the pressure gauge 14 and the screw setting 48.
  • the cursor 53 is subject to the action of two springs, and they exert on the manometric membrane 14 a fraction of the total force, in proportion to their respective stiffness; when the probe 17 is pressed, the lever 51 compresses the additional spring 50, and the return spring 45 then acts practically alone against the movement of the pressure gauge membrane 14.
  • the two springs 45, 50 are in service and there is a vacuum operation, while, when the probe 17 is depressed by the front stop shoulder of the mask snout, the additional spring 50 of the modifying return means of the speed of operation is put directly out of service D raticu and directly, only the return spring 45 acting / on the control diaphragm is in service and there is an overpressure operation.
  • the tip may also include additional rings allowing the connection of the input of the micro-regulator to the mask, for example by screwing or fitting.
