Definitions
- the present invention relates to a breathing tip. More particularly, the present invention relates to a mouthpiece for delivering gases to a user and intended to be used with a device for breathing under water, for example a diving regulator or a snorkel.
- the present invention aims to solve the various technical problems mentioned above.
- the present invention aims to provide a mouthpiece to limit the recurring inconvenience due to traditional mouths, including irritation of the gums and muscle pain, facilitating its proper maintenance and use in the mouth of the user.
- a mouthpiece comprising: a U-shaped vestibular flap having a central portion having a through opening for the passage of gas, and two side portions extending on each side of the central portion; to form the two branches of the U,
- a lingual flap comprising a central portion and two lateral portions extending on each side of the central portion
- a vestibulo-lingual tray intended to be positioned in the occlusal plane of the user's jaw, the vestibulo-lingual tray connecting at least partially the vestibular flap and the lingual flap,
- central portion of the lingual flap is devoid of an upper portion extending above the vestibulo-lingual tray.
- the mouth has a central portion of the lingual flap positioned only behind the mandibular incisors: such a central portion allows, in particular, when positioning the mandibular incisors in front thereof and when positioning the tongue on that to provide anteroposterior guidance of the closing movement of the jaw on the mouth, which promotes the relaxation of the muscles of the jaw.
- the central portion of the lingual flap may comprise a height less than or equal to that of the mandibular incisors, so as not to come into contact with the gingiva or with the sub-lingual brake of the user.
- the lateral portions of the lingual flap are devoid of bottom portion extending below the vestibul lingual plateau. This provides a greater lateral space for the tongue, especially when it bears on the central portion of the lingual flap. This preserves a freedom of movement of the tongue, while maintaining the mandible relative to the mouth.
- the central portion of the vestibul lingual plateau is a recessed portion of the vestibul lingual plateau, so as to leave free the portion of the occlusal plane located between at least a portion of the central incisors of the user, preferably between at least one part of the central and lateral incisors of the user.
- the absence of a central portion of the vestibulo-lingual tray improves the circulation of air in the mouth, when the mouth is positioned there.
- the positioning of the tongue on the central portion of the lingual flap does not close the opening through the circulation of gas between the outside and the mouth.
- the gases can flow freely under or next to the central portion of the lingual flap, without being impeded by the language of the user.
- the central portion of the vestibul lingual plate has a width equal to that of the central portion of the lingual flap.
- the lateral portions of the buccolingual plateau comprise a light in continuity with the central portion of the vestibul lingual plateau.
- the lateral portions of the vestibul lingual plateau thus make it possible to extend the opening present at the central portion of the vestibul lingual plateau, for example to facilitate the air circulation between the through opening for the passage of gases and the inside of the mouth of the user.
- the central portion of the vestibulo-lingual plate and the lights of the lateral portions of the vestibul lingual plate have a width equal to that of the through opening for the passage of gases.
- the vestibulo-lingual plate has an oblong slot, opposite the through opening for the passage of gases, to facilitate the flow of gas through the mouth, while limiting the risk of obstruction of the mouth by the language of the user.
- the lateral portions of the vestibular flap have a convex outer surface.
- a convex surface increases the comfort of the internal faces of the cheeks of the user on the outer lateral faces of the mouth.
- the curved surface also contributes to the stability of the mouth in the mouth, via the muscles of the muscles and the muscles that form the internal muscular structure of the cheeks and provide the bulk of the tonicity and volume of the cheeks.
- the vestibular flap is formed by two materials: a first material forming a median portion of the vestibular flap, and a second material forming a peripheral portion of the vestibular flap.
- a first material forming a median portion of the vestibular flap
- a second material forming a peripheral portion of the vestibular flap.
- the second material may be a flexible material, for example silicone.
- the second material is that arranged peripherally around the vestibular flap, that is to say the material intended to come into contact with the gums and mucous membranes of the user.
- the second material is so chosen flexible, to limit the attacks on these sensitive and fragile areas of the mouth.
- the second material is chosen so as to spare the attached gingiva and provide a soft contact with the free gingiva.
- the first material may be a rigid material, for example
- the first material makes it possible to confer on the mouthpiece its robustness and a small deformation, which makes it possible to guarantee the good mechanical cooperation of the mouthpiece with a regulator or with a snorkel, to avoid leaks.
- the first material has a curved outer surface at the side portions of the vestibular flap.
- the lateral portions of the vestibular flap may have a surface exposed first material, for example at the bulging parts coming into contact with the inside of the cheeks. These are less fragile areas than the gums or lateral brakes that are in contact with the upper and lower peripheral parts of the vestibular flap.
- the central portion of the lingual flap is intended to be positioned behind at least a portion of the lower central incisors of the user.
- the lateral portions of the vestibular flap have a height which decreases away from the central portion.
- a whistle-like emergence profile is thus obtained, which limits the contact with the upper and lower lateral brakes.
- FIG. 1 is a perspective view, three quarters front view, of a mouthpiece according to the invention
- FIG. 2 is a perspective view, rear three quarter view, of the mouth shown in FIG. 1, and
- FIGS. 3, 4 and 5 are respectively rear, top and bottom views of the mouthpiece shown in FIG. 1. DETAILED DESCRIPTION OF THE INVENTION
- FIGS 1, 2, 3, 4 and 5 show different views of an embodiment of a mouth 1 according to the invention.
- the mouth 1 comprises, at one end, a coupling portion 2, standard, for connecting the mouth 1 to a gas conveying means, for example an expander or a tuba.
- the coupling portion 2 thus comprises an inner through opening 4 allowing the flow of gas from the gas conveying means to the inside of the mouth.
- the mouth 1 comprises a U-shaped portion 6 intended to be positioned in the mouth.
- the U-shaped part 6 comprises a vestibular flap 8, a lingual flap 10 and a vestibul lingual tray 12.
- the vestibul lingual tray 12 connects, at least partially, the vestibular flap 8 and the lingual flap 10, and is intended for to be positioned in the occlusal plane of the user's jaw, that is to say to be positioned substantially in a horizontal plane when the user stands upright, right.
- the gases traveling in the through opening 4 of the mouth 1 flow in a direction included in the plane of the buccolingual tray 12.
- the mouth extends in a plane P (see Figures 4 and 5) corresponding to that of the vestibulo-lingual tray 12.
- the plane P of the mouth 1 corresponds to the occlusal plane of the jaw of the user.
- Figures 4 and 5 show the mouth 1 seen from above and below respectively, with respect to this plane P.
- the vestibular flap 8 also has a U shape.
- the vestibular flap 8 comprises a central portion 14 integral with the coupling portion 2, which is traversed by the through opening 4 to allow the passage of gases through the vestibular flap 8
- the vestibular flap 8 also comprises two lateral portions 16, 18, extending on each side of the central portion 14 so as to form the two branches of the U of the vestibular flap 8.
- the vestibular flap 8 extends on either side of the vestibul lingual plateau 12, that is to say above and below said vestibul lingual plateau 12, in a direction substantially transverse to the plane P.
- the vestibular flap 8 may be substantially symmetrical relative to the plane P.
- the central portion 14 of the vestibular flap 8 may comprise a notch 15 on the upper and lower ends.
- the lateral portions 16, 18 of the vestibular flap 8 have a height, that is to say a dimension perpendicular to the plane P, which decreases towards the distal end of each lateral portion 16, 18, that is to say, which decreases when one moves away from the central portion 14. A whistle emergence profile is thus obtained which limits the contacts and the injuries on the lateral brakes of the user.
- the outer surface of the lateral portions 16, 18 of the vestibular flap 8, that is to say the surfaces located near the plane P but opposite the vestibul lingual plateau 12, have a convex shape, so as to present a contact that is both important but soft, with the inside of the user's cheeks.
- the lingual flap 10 also has, viewed from above (see FIG. 4), a U shape.
- the lingual flap 10 comprises a central portion 20, and two lateral portions 22, 24.
- the central portion 20 extends below the vestibulo-lingual plateau 12, that is to say below the plane P, while the side portions 22, 24, or palatal flaps, extend above the buccolingual plateau 12, that is, to say above the plane P.
- the central portion 20 of the lingual flap 10 has a curved shape, with upper and lower surfaces rounded so as not to damage the gingiva located under the incisors, and secondly to provide a space for accommodating a portion. of the language.
- the central portion 20 of the lingual flap is intended to be positioned on the rear part of the mandibular incisors of the user. Thanks to the central portion 20, the mouth is thus locked in anteroposterior position by the positioning of the incisors between the lower portion of the central portion 14 of the vestibular flap 8 and the central portion 20 of the lingual flap 10.
- the central portion 20 of the lingual flap 10 also makes it possible to form a support zone on which the tongue can rest, without this blocking the flow of gases through the through opening 4, as is more specifically described. lower.
- the lateral portions 22, 24, or palatal flaps have a flattened and curved shape to be positioned on the inner surface of premolars, as well as a portion of the palate, to maintain the mouth in position in the mouth.
- the lateral portions 22, 24 and central 20 of the lingual flap 10 are arranged in continuity with each other, so as not to create a rupture zone, and form, seen from behind, a U-shape wherein the central portion 20 forms the lower portion of the U and the side portions 22, 24 form the two upper parts of the U branches (see Figure 3).
- the buccolingual tray 12 is disposed in the plane P of the mouthpiece, and is intended to be positioned in the occlusal plane of the user.
- the vestibul lingual tray 12 also has, seen from above (see FIG. 4), a U-shape.
- the vestibul lingual tray 12 has a central portion 26 and two lateral portions 28 30.
- the central portion 26 is positioned between the central portion 20 of the lingual flap and the through opening 4.
- the central portion 26 is empty, that is to say that it is devoid of material and only corresponds to a volume
- the central portion 26 allows in particular to let air circulate between the through opening 4 and the inside of the mouth.
- the side portions 28, 30 have a flattened shape disposed in the plane P of the mouth. They are intended to come into contact with the occlusal surfaces of the pre-molars and molars of the user.
- the lateral portions 28, 30 may also comprise a light, respectively 32 and 34, arranged at the junction with the central portion 26. The combination of the central portion 26 and the slots 32, 34 thus makes it possible to form an oblong recess in the vestibulo-lingual tray 12 whose width corresponds, preferably, to the width of the through opening 4 and which is opposite said through opening 4.
- the mouth 1 may be formed of a single material, preferably plastic and moldable, for example of TPU, or may comprise a second material, flexible, arranged along the upper and lower peripheral contour of the vestibular flap 8.
- the second material can be overmoulded, bi-injected, etc., on the first material.
- the second material aims to limit aggression of the user's gums, making the contact with the mouth softer. It is thus possible to choose a second silicone material.
- the mouthpiece according to the present invention makes it possible to improve the comfort of the user, while limiting the aggressions of the sensitive areas of the mouth, such as the gums or the brakes.
- This provides a mouthpiece of universal type with a limited manufacturing cost and a minimum of inconvenience for the user.
