    [0001] The present invention relates to a face mask for inhalation, adapted for the administration of a gas or a therapeutic molecule in the context of an inhalation treatment, in particular in children. A face mask for inhalation is a medical device that promotes the entry of respiratory gas into the body of a person with temporary or permanent difficulties in taking the respiratory reflex. It can also be used to diffuse a therapeutic molecule into a patient's body through his or her respiratory tract. The airways leave the nose and mouth and extend to the pulmonary alveoli. They provide breathing for an individual, and are therefore essential for survival. The entry of respiratory gas is at the level of the nose and / or mouth, and the pulmonary alveoli are the seat of gas exchange with the internal environment of the human body. Oxygen is absorbed by the body while carbon dioxide is released into the air.
    [0002] The lungs collect all the pulmonary alveoli. In order to ensure their function, the exchange surface with the internal environment is particularly large in these organs. This specificity makes the lungs a privileged area for the absorption of therapeutic molecules. The nose is lined with mucous membranes rich in blood vessels. The mucosa is particularly covered with nasal mucus, which traps the incoming molecules and allows their presentation to nerve endings for purposes of olfaction. The nose is also provided with a ciliary system whose role is to filter the inspired air to avoid the inspiration of organisms or foreign molecules. It should therefore be understood that the nose is an obstacle to the propagation of therapeutic molecules to the lungs, and therefore, the inhalation of a drug must be preferably by oral respiration. However, nasal inhalation is a reflex, so it is difficult to force the patient to inhale through the mouth, especially when the patient is a child or a baby. By way of example, a conventional inhalation face mask such as that described in patent application EP 1 389 482 is an oro-nasal respiratory mask, that is to say which surrounds the mouth and the nose when is applied to the patient's face. It has a single cavity and an opening allowing the entry of an element on the mask such as a source of 02 diffusion. This mask therefore makes it possible to promote the patient's breathing, but is not very suitable for inhaling therapeutic molecules because they can not be directed preferentially towards one or the other of the inputs of the respiratory system. The patent application WO 2012/173 992 discloses a face mask for inhalation having a portion housing the nose and a portion housing the patient's mouth and an opening aligned with the nose for inhalation of therapeutic molecules by the patient. This solution promotes the inhalation of therapeutic molecules through the nose, which is an obstacle to optimal deposition of therapeutic molecules in the lungs of the patient. US Patent Application 2005/217678 discloses a face mask for inhalation having an intraoral part. As a result, the inspiration constraint by the mouth is ensured, but the intraoral part generates a real discomfort for the patient, and is particularly unsuitable when this patient is an infant. Application for a utility certificate CN 203090169 U includes a respirator to reassure the child and administer medication. The mask includes a pipe penetrating into the oral cavity of the patient, which however is not a fully comfortable solution especially in children and infants. Currently, there are therefore inhalation masks forcing the patient to breathe through the mouth via mouthparts. These devices are nevertheless uncomfortable for the patient and particularly unsuitable for young patients, which hampers the inhalation of the drug and inconveniences the patient. In addition, such devices are complex to manufacture and / or use. The object of the invention is to overcome the aforementioned drawbacks. In particular, one of the aims of the invention is to provide a face mask for inhalation designed to allow inhalation and pulmonary deposition of the optimal therapeutic molecules without generating strong constraints or discomfort during the use of the mask by the patient. In particular, an object of the invention is to provide such a mask allowing inhalation of the gas or the therapeutic molecule only by the mouth.
    [0003] Another object of the invention is to propose such a mask in order to reduce the risk of the patient refusing to use the mask. Another object of the invention is to provide such a mask which is simple to design and use.
    [0004] For this purpose, the present invention relates to a mask comprising a body of which at least one wall delimits an interior volume intended to engage a portion of the face of a user including his nose and his mouth, the body having a first opening in communication with a user. connecting means to a source of gas or a therapeutic molecule, and a second opening bordered by a lip intended to be applied against said portion of the face of the user, characterized in that it comprises a watertight partition delimiting, in the interior volume, an upper chamber intended to house the user's nose and a lower chamber containing said first opening and intended to house the mouth of the user when said mask is worn. The mask encompasses both the patient's nose and mouth. The partition allows to separate in a sealed manner the chamber receiving the nose, the chamber receiving the mouth of the user. Only the mouth-receiving chamber communicates the user's airway with the source generating the respiratory gas or the therapeutic molecule via the connecting means R1. The inhalation of the individual is therefore forced to be done only by the mouth. According to one embodiment of the invention, the bulkhead is bordered by a second lip intended to be applied above the upper lip of the user. Advantageously, the second lip merges at its ends with the first lip. The lips of the mask thus joined make it possible to seal the labial perimeter and the nose. This feature enhances the seal between the two chambers and helps to constrain inhalation of the gas or therapeutic molecule through the mouth. Preferably, the mask consists of a single piece molded ergonomically for example by an injection molding process. According to one embodiment of the invention, the upper chamber comprises a expiratory unidirectional valve. The expiratory unidirectional valve is intended to allow the exit of exhaled air by the patient, to prohibit the entry of air into this part of the mask and is intended to improve the comfort of the patient. The valve helps promote the inspiratory effort of the patient through the mouth.
    [0005] According to one embodiment of the invention, the lip has an overall trilobic shape. The trilobal section mask is specifically adapted for very young children, since in this population, the nose-to-mouth distance is very small. This adaptation of the mask model makes it possible in particular to limit gas exchanges directly between the nasal chamber and the ambient air. According to one embodiment of the invention, the lip has an overall piriform shape. The piriform lip mask is particularly suitable for adults and children. In fact, these individuals have physiognomic features in the oro-nasal sphere, and more particularly as regards the nose-mouth distance, but the distance is greater than that observed for infants and very young children. The mask of this type thus makes it possible to take into account these imperatives of the user's face, in particular by ensuring the tightness of the contact 15 between the lips of the mask and the face. According to one embodiment of the invention, the two chambers are interconnected by connecting means. The body of the mask may, for example, be split in such a way that the two chambers are disjointed, for example, to facilitate storage. In such a case, connecting means ensure the unity of the mask. According to one embodiment of the invention, the mask is made of a plastic material or an elastomeric material. When the plastic material is an elastomer, the use of a silicone-based material is preferred. The silicone has the advantage of being as neutral as possible from a biological point of view, making it an ideal material for the manufacture of an element intended to be in contact with the human body. There are nevertheless on the market synthetic elastomers which also have all the characteristics necessary for the development of such a mask. Such elastomers are of course considered in the context of the present invention. The invention also relates to an inhalation device as described above comprising an inhalation mask as described above and an inhalation chamber or a nebulizer, the inhalation chamber and the nebulizer being connected to the connecting means of the invention. mask.
    [0006] The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment. Fig. 1 is a front perspective view of a face mask for inhalation according to an embodiment of the invention, FIG. 2 shows a rear perspective view of a face mask for inhalation according to an embodiment of the invention; FIG. 3 shows a cross-sectional view of a face mask for inhalation according to one embodiment of the invention, FIG. 4 shows a rear view of a face mask for inhalation according to one embodiment of the invention, FIG. 5 shows a rear view of a first embodiment of a face mask for inhalation adapted to the facial physiognomy of an infant according to one embodiment of the invention, Figs. 6 and 7 show two rear views of two inhalation masks according to FIGS. 4 and 5, and provided with an exhalation valve. Fig. 8 is a view of a face mask for inhalation according to one embodiment of the invention, coupled to an inhalation chamber. The invention presented in connection with FIGS. 1 to 7 relates to a mask (M) comprising a body (C) of which at least one wall (P1, P2, P3) delimits an interior volume (Vi) intended to engage a portion of the face of a user including his nose and its mouth, the body (C) having a first opening (01) in communication with a connecting means (R1) to a source of gas or a therapeutic molecule, and a second opening (02) bordered by a lip ( L1) intended to be applied against said portion of the face of the user, characterized in that it comprises a watertight partition (C1) delimiting, in the interior volume (Vi), an upper chamber (B1) intended to house the nose of the user and a lower chamber (B2) containing said first opening (01) and intended to accommodate the mouth of the user when said mask is worn.
    [0007] It is a face mask for inhalation, suitable for the administration of a gas or a therapeutic molecule in the context of an inhalation treatment. The facial mask for inhalation according to the invention is, in particular but without limitation, designed for use by a child, an infant and / or a premature infant.
    [0008] In Figs. 1 to 7, the inhalation face mask M comprises a body C having a volume Vi opening through an opening O1 in connection means R1 to a device, such as an inhalation device, a nebulizer or any other source generating a gas or a therapeutic molecule in volatile form.
    [0009] In the embodiment shown in connection with FIGS. 1, 2, 3 and 4, the body C has the overall shape of a pyramid section with three faces and curved edges. It is thus delimited globally by three walls P1, P2 and P3. This embodiment is particularly relevant for producing a mask according to the invention that meets the morphological requirements of an adult or a child.
    [0010] In the embodiments shown in relation to FIGS. 5 and 7, the body C has the overall shape of a sphere section. It is thus defined globally by three identical walls P1, P2 and P3. This embodiment is particularly relevant for producing a mask that meets the morphological requirements of an infant or premature baby.
    [0011] The connection means R1 consists in these embodiments, in a hollow cylinder portion allowing the engagement of the mask with a complementary device, such as an inhalation chamber as shown in FIG. 8 or a nebulizer. As can be seen in FIG. 2, the body C is defined by an opening 02 bordered by a lip L1 intended to be applied around the oro-nasal sphere of the user. The lip L1 is curved towards the inside of the body C of the mask M, so that the free edge of the lip L1 is not in contact with the user of the mask. The lip L1 of the inhalation facial mask M shown in FIG. 4 shows in its rear view a pear-shaped geometry. It is particularly suitable for children whose nose-mouth distance begins to increase significantly. In a different way, FIG. 5 presents a version of the mask of the invention, adapted to users whose nose-mouth distance is shorter, that is to say adapted to infants and premature. The lip L1 of this mask has in its rear view of FIG. 5, a trilobic geometry. We observe in Figs. 2 to 7, the presence of a partition Cl, delimiting inside the body C of the mask M, two chambers, one upper B1 and the other lower B2. The upper chamber B1 is designed to receive the nose of the user while the lower chamber B2 is provided to receive the mouth of the user when the mask M is worn. Cl partition extends as shown in Figs. 2 and 4 to 7, over the entire width of the mask, from the wall P1 to the wall P2. It can be seen in FIG. 3 that the partition C1 also extends over the entire depth of the mask. It is connected, in the laying position of the mask by a person in standing position, above the connection means R1. The free edge of the partition C1 is delimited by a second lip L2 (FIG 3). The lip L2 is intended to be placed in contact with the face of the user and precisely above his upper lip, and offset his nostrils.
    [0012] Fig. 3 also shows that the second lip L2 is connected at both ends with the lip L1. As a result, lips L1 and L2 are in continuity. This provides a seal around the lip and around the nose. The upper chamber B1 includes only the nose, while the lower chamber B2 includes only the mouth of the user of the mask. The chambers B1 and B2 are separated in a sealed manner from one another. The connecting means R1 communicates with the mouth chamber B2 of the face mask for inhalation M. The inhalation is thus forced to be done exclusively by the mouth of the user. It is performed without casing likely to penetrate the mouth. The use of the mask M is particularly easy, especially for caring for infants and infants. According to another variant shown in Figs. 6 and 7, an expiratory valve V1 is disposed at an opening in the upper chamber or nasal chamber B 1. It is a unidirectional valve which is positioned at a rounded wall junction between the wall P1 and the wall P2. It allows the user of the mask to expel out of the mask and without hindrance the air contained in his lungs. The mask of the invention does not cause any discomfort because of its use, especially in the oral cavity. It reduces the risk of patient refusal to use the mask.
    [0013] It facilitates its use by carers, whether professional or non-professional. It will be noted that the mask of the invention may consist, in a variant embodiment not shown, of two disjoint chambers, the two chambers being joined by connecting means.
    [0014] In FIG. 8 is an inhalation device D. A face mask for inhalation M, such as one of those described in FIGS. 1 to 7, is connected via its connecting means R1 to a C1 inhalation chamber. A source generating a gas or a therapeutic molecule, such as an aerosol dispensing bottle, can be connected to the second E2 end of the inhalation chamber to allow the diffusion of the molecule or gas inside the C inhalation chamber during treatment and after actuation of the aerosol. During the inspiration / inhalation phase caused by the patient, the therapeutic molecule will diffuse from the inhalation chamber Ci to the lower chamber B2 of the mask M via the connecting means R1. The partition C1 will prevent the therapeutic molecule or the gas from reaching the upper chamber B1, thus permitting the inhalation of the therapeutic molecule or gas only by the mouth of the user.
