  • FIG. 1 represents an elastically deformable nasal tip
  • the nosepiece comprises a conduit 3 opening into an opening 4 located at a first end 5 of the nosepiece intended to be introduced into the nose of an individual, and into an opening 6 located at a second end 7 of the endpiece equipped with means for sealing and removable fastening in an opening of the body of a device for suctioning nasal secretions.
  • the opening 6 of the second end is closed by an impermeable membrane 8 elastically deformable under the effect of a depression created in the body of the suction device by a vacuum source and intended to form reservoir for nasal secretions.
  • the nosepiece 2 comprises non-return means avoiding the emptying of the nosepiece when a depression ceases to be exerted on the elastically deformable waterproof membrane.
  • the non-return means comprise a substantially cylindrical elastically deformable body 9 sealingly fixed in a housing 11 formed axially in the nosepiece and comprising a longitudinal bore 12 forming part of the free section of the duct 3.
  • the piercing 12 of the body 9 is in fluid communication upstream with the opening 4 of the first end of the nosepiece and downstream with the opening 6 of the second end of the nosepiece, and therefore with the space inside delimited by the membrane 8.
  • the elastically deformable body 9 comprises a non-return valve 13 bearing on a valve seat 14, the valve / valve seat assembly being displaceable and / or deformable between a closed position of the conduit and a draining position of the nozzle. nasal under pressure from the nosepiece.
  • the non-return valve is movable between a shutter position of the conduit and a non-shutter position of the conduit under the effect of a vacuum created in the body of the suction device.
  • the non-sealing position of the duct is shown in dashed lines in FIG.
  • the non-return valve 13 is formed substantially at the end of the body 9 facing the first end of the nosepiece, the valve seat 14 being formed by an inner shoulder formed on the walls of the conduit.
  • the non-return valve consists of a circular flap 15 fixed to the inside wall of the body 9 by a flexible tongue 16.
  • impermeable membrane 8 comprises a peripheral bead 17 intended to be retained in an annular groove 18 formed on the outer surface of the body 9.
  • the body 9 comprises annular ribs 19 formed on its outer surface and for clamping the membrane 8 against the walls of the housing 11 so as to ensure the strength and tightness of the assembly.
  • Figure 3 shows a nasal secretion suction device 21 comprising a nasal tip.
  • the suction nasal secretion device also comprises a hollow body 22 delimiting a vacuum chamber 23 connected to an electric pump 24 intended to create a depression in the latter.
  • the electric pump is driven by an electric motor 25 powered by batteries 26 housed in the hollow body.
  • the hollow body 22 comprises, at the level of the vacuum chamber, an opening 25 intended to cooperate with the fastening means provided on the nosepiece.
  • These fixing means comprise an annular rib 26 formed on the outer surface of a cylindrical portion 27 formed at the second end of the nosepiece.
  • the annular rib 28 is intended to cooperate with an annular groove 29 formed at the opening of the hollow body.
  • annular ribs 30 are formed on the outer surface of the cylindrical portion, these two ribs being intended to cooperate with the opening of the hollow body to seal the attachment of the nosepiece on the hollow body.
  • a push button 31 is provided on the hollow body 22 to allow the power supply of the electric motor 25 by the batteries 26 in its depressed position.
  • the electric pump 24 creates a vacuum in the vacuum chamber 23 which causes the deformation of the impermeable membrane 8.
  • the deformation of the impermeable membrane transmits the depression in the bore 12 of the body 9. This results in a deformation of the non-return valve 13 which allows aspiration of the nasal secretions.
  • the non-return valve 13 resumes bearing against the shoulder 14 and again closes the duct 3 under the effect of the pressure exerted by the membrane which tends to resume its initial form.
  • the non-return valve 14 thus makes it possible to avoid unwanted emptying of the nosepiece and the reservoir intended to receive the secretions.
  • the membrane 8 returns to its original shape and the pressure performed with the finger on the nosepiece is stopped.
  • the valve / valve seat assembly then resumes its original shape and the check valve again closes the duct 3 of the nosepiece. At this time, the nosepiece can be reused.
  • valve / valve seat assembly systematically empties the reservoir formed by the membrane 8, before removing the nosepiece of the suction device. Therefore, it is no longer necessary to provide an opening 25 of large diameter in the suction device to allow the passage of a tank of big size. Thus, it is possible to make nasal tips of smaller diameter, and thus reduce the manufacturing costs of the latter and the volume of waste.
  • the cylindrical portion 27 is removed and the annular ribs 28 and 30 are formed directly on the cylindrical portion 32 partially defining the conduit 3.
  • This structure of the tip allows the realization an opening 25 of the suction device of very small diameter.
  • the edge of the flap 15, opposite to that connected to the tongue 16, is slightly flattened to facilitate the emptying of the tank.
  • the elastically deformable body 9 has a mark intended to be positioned opposite a complementary mark on the nosepiece.
  • the invention is not limited to the embodiments of this nosepiece, described above by way of example, it encompasses all the variants.
