Definitions

• the present invention relates to the general technical field of medical devices for the oxygenation of a patient. More specifically, the present invention relates to an intraoral device that can be inserted into the mouth of a patient suffering from trismus and having a limited or even non-existent mouth opening.
• the mask according to WO 2005/097245 can be inserted into the mouth of a patient with a limited mouth opening.
• the mask according to WO 2005/097245 is liable to cause discomfort for the patient.
• Document FR 2 700 473 describes an intra-oral respiratory mouthpiece having a vestibulo-lingual plug extending projecting from the rear face of the upper and lower vestibules.
• US 3,107,667 discloses a mouthpiece bearing dental impressions projecting from the rear face of the outermost area of said mouthpiece.
• US 3,107,667 teaches to provide a custom molded device from the user's dentition, which makes it impossible for people with trismus to insert it.
• the height of the device is "preferably 56 mm", while the average mouth opening in the population is 50 mm. It is therefore suitable for the general population, but not for the target population for the mouth opening is nil or reduced, because its insertion would become traumatic or even impossible due to the morphological mismatch between the vestibular space and the device.
• An object of the present invention is to propose an intraoral device making it possible to overcome the aforementioned drawbacks.
• the invention provides an intraoral device configured to be inserted into the oral cavity of a patient, the device comprising:
• the central rear face having a first radius of curvature and the peripheral rear face having a second peripheral radius of curvature, the first radius of curvature being greater than the second radius of curvature
• Preferred but non-limiting aspects of the intraoral device according to the invention are the following:
• the intraoral device includes:
• the intraoral device has an overall Y shape. It extends globally along a longitudinal axis A-A' forming an axis of revolution for the tubular element 2.
• the tip 1 comprises an oval and curved body composed of a central part 11 and a peripheral part 12.
• the height of the central 11 and peripheral 12 parts is between 15 and 25 millimeters. This makes it possible to limit the discomfort associated with the insertion of the endpiece 1 in the mouth of the patient, in particular when the mouth opening of the patient is limited or non-existent.
• the tip 1 also includes a through opening 13 formed in the center of the body. More specifically, this through opening 13 extends between the front 14 and rear 15 faces of the central part of the body. This through opening 13 defines a conduit for the passage of a gas to the oral cavity of the patient.
• the central and peripheral parts 11, 12 of the end piece 1 are preferably made of a flexible material, that is to say a material whose Shore hardness is between 10 and 70 Shore A, preferably between 20 and 60 Shore A, and even more preferably between 30 and 50 Shore A. This makes it possible to have a tip 1 that is sufficiently rigid to facilitate its insertion into the patient's mouth, while being flexible enough to conform to the contour of the arch dental.
• the material constituting the tip 1 is for example a medical grade polymer (polyethylene, polypropylene, polycarbonate, etc.), a medical grade elastomer, a silicone, a polyurethane, an epoxy, a parylene.
• the thickness of the central and peripheral parts 11, 12 is advantageously between 1 and 10 millimeters, preferably between 2 and 6 millimeters, and even more preferably between 3 and 5 millimeters, in particular substantially equal to 4 millimeters.
• the inventors have in fact discovered that these ranges of thickness make it possible to minimize the risk of gas leaking at the level of the patient's mouth when the device is inserted into the oral cavity and a gas is injected through the tubular element. 2.
• the central part 11 When the device is inserted into the oral cavity, the central part 11 extends between the patient's lips and teeth. More specifically, the central part 11 includes:
• the front face 14 of the central part can be curved in two directions to adapt to the shape of the patient's mouth and thus limit the risk of leakage during the injection of gas through the intraoral device.
• upper and lower grooves 17 can be made in the front face 14 of the central part. These grooves 17 extend transversely to the central part between its side edges. Each groove 17 is configured to receive a respective lip of the patient:
• upper and lower grooves 17 in the central front face 14 makes it possible to limit discomfort for the patient while limiting the risks of leakage during the injection of gas through the intraoral device.
• the rear face 15 of the central part 11 is smooth.
• the fact that the rear face 15 of the central part 11 has no component extending protruding allows the insertion of the intraoral device in the mouth of a patient whose mouth opening does not exist.
• the rear face of the central part 11 has a first radius of curvature R c .
• This first radius of curvature R c is chosen to conform the rear face of the central part 11 to the curvature of the dental arch portion delimited by the patient's canines.
• the peripheral part 12 is composed of two fins each extending from a respective side edge of the central part 11.
• each fin joins a respective side edge of the central part at the level of a respective edge 18.
• the free end 16 of each fin corresponds to the area of the fin closest to the bottom of the oral cavity when the device is inserted into the patient's mouth.
• the distance L between the edges is between 30 and 60 millimeters, preferably between 40 and 50 millimeters. This allows a fine adaptation of the tip 1 to the morphology of the patient's mouth.
• the peripheral part 12 extends between the cheeks and the teeth of the patient. More precisely :
• the rear face of the peripheral part 12 has a second radius of curvature R p less than the first radius of curvature R c .
• This second radius of curvature R p is chosen to conform the rear face of the peripheral part to the curvature of the dental arch portions extending between the canines and the molars of the patient.
• the fact that the rear faces of the central and peripheral parts 11, 12 have different radii of curvature R c , R p (with R c > R p ) allows the endpiece to have a shape that is particularly complementary to the shape of the buccal vestibule in which the tip is intended to be housed, which makes it possible to limit the risks of leakage while guaranteeing acceptable comfort for the patient.
• the distance between the free ends of the fins is between 40 and 80 millimeters, preferably between 50 and 70 millimeters, and even more preferably between 55 and 65 millimeters, in particular substantially equal to 60 millimeters. This makes it easier to insert the device into the mouth of a patient with a limited mouth opening while guaranteeing the tip a curvature allowing it to conform to the oral morphology of the patient.
• the rear face 15 of the peripheral part 12 is smooth to allow insertion of the intraoral device in the mouth of a patient whose mouth opening is non-existent.
• the tubular element 2 makes it possible to connect the intraoral device to an oxygen source (not shown).
• the tubular element 2 comprises:
• the tubular element 2 can be removable.
• the tubular element 2 can be secured to the end piece by shape cooperation, for example by force-fitting the proximal end 21 into the through opening 13.
• the tubular element 2 can be irremovably fixed to the end piece 1.
• the proximal end 21 of the tubular element 2 comprises a substantially planar base intended to be embedded in the mass of the endpiece 1 during the molding of the intraoral device.
• connection means configured to be connected to oxygen delivery means (not shown).
• the invention described above makes it possible to have an intraoral device that can be inserted into the mouth of a patient suffering from trismus and having a limited or even non-existent mouth opening.
• the material constituting the tip can be flavored in order to limit the risks of rejection of the intraoral device by the patient.
