    DESCRIPTION
    Auxiliary device for dental procedure, method and uses thereof Technical field
    The present invention concerns in general the field of dental devices. In particular, the invention concerns an auxiliary device for dental procedures, a method, and uses of the auxiliary device. The aforementioned auxiliary device does not obstruct the oral opening of a patient, thus allowing a healthcare professional to work normally during the dental procedure, being able to treat any accessible space or tissue through the patient's mouth.
    Background of the invention
    A device for dental use is known from US-B2-7300401 which is placed in the mouth of a patient during the dental procedure for retraction of the mouth and expulsion of saliva. The aforementioned device includes a suction front part, a right cheek retraction part, a left cheek retraction portion, and a suction portion. Likewise, the device is constructed by a single, rigid piece of elastic and tubular material, with a cylindrical shape or other cross-sectional shape.
    A device for keeping the operating field dry during a dental procedure is known from US-B2-7785105. The device includes a U-shaped element to hold the patient's tongue during the dental procedure. In addition, it includes some lip retractors that extend arched by the cheeks. In some embodiments, the device also includes a saliva ejector.
    By the Chinese utility model CN-Y-201115660 a device for opening a patient's mouth is known during a dental procedure equipped with lateral retractors and also includes a saliva aspiration function by means of two tubular mechanisms, for filtration / Evacuation of saliva, which are positioned in the back of the patient's mouth during the procedure. With the aforementioned suction function, contamination can be reduced due to the air present in the room or due to an inhaler.
    From EP-B1-1131015 a dental device of intraoral illumination is also known that allows to illuminate the interior of the oral cavity of a patient during a dental procedure and thus avoid problems of illumination. The device

    Illumination includes an occlusion device designed to fit the patient's teeth so that, during the dental procedure, he can rest his jaws and the device is fixed in his mouth. Also, the dental device has a retractor for the tongue and cheeks that allows to isolate and protect the tongue and tissue of the patient's cheeks during the medical procedure. The device can also incorporate fluid evacuation channels that allow the extraction of the fluids present inside the patient's oral cavity during the dental procedure.
    However, at present there is no known device for dental procedure that is held in or in the mouth of a patient during the dental procedure and that includes a barrier mechanism, between the inside and outside of the patient's mouth, through the generation of a flow of a gaseous fluid, or air curtain, providing greater protection by allowing the filtration of pathogens during the dental procedure.
    Exposition of the invention
    According to a first aspect, the present invention provides an auxiliary device for dental procedure, intended to be applied in a peribucal area of a patient, or adjacent to it, that is, the space comprised by the volume of 3 cm around the entire length of the vermilion lip, commissure included. The proposed auxiliary device does not obstruct the oral opening so that a healthcare professional can work normally by treating any accessible space or tissue through the patient's mouth (such as the oral cavity, nasal cavity, larynx, pharynx, esophagus or maxillary sinuses) .
    Typically, the proposed auxiliary device comprises a member generating a flow of a gaseous fluid, or air curtain, which exerts a barrier effect between an interior area of the patient's mouth and the outside of the mouth, and a support of the said generating member of a flow of a gaseous fluid that keeps it arranged in an area close to said peribucal zone.
    In this way, the proposed auxiliary device prevents or minimizes the passage of sprays, microdroplets, drops, or other particles, as well as pathogenic agents (such as viruses, fungi, bacteria, prions, etc.) from inside the oral cavity to external and vice versa, thus avoiding direct cross contamination between patient-healthcare professional, and vice versa, as well as indirect contamination (that is, the one that is carried out through the environmental contamination of a dental box or work area of a healthcare professional or by the tooling, instruments, etc. in such a way that the infection of the patient or healthcare professional can originate due to a previous patient).

    Likewise, the proposed auxiliary device allows the healthcare professional to work normally and without obstructions in the entire oral cavity, and can be used autonomously or in conjunction with a rubber dam.
    The proposed auxiliary device also prevents the exit of the patient's mouth from particles resulting from the removal of dental restorative materials potentially dangerous to health (for example dental amalgams) which is solved today using methodical methods based on a combination of suction hoods, rubber dikes and specialized masks.
    Preferably, the gas flow is a laminar flow.
    In an example of realization, said support includes an oral expansion element comprising at least one portion that provides supports in distal areas of the mouth for cheek separation (oral expansion) during the dental procedure. Alternatively, in another exemplary embodiment, the support includes an oral expansion element comprising at least one portion that provides supports in labial areas for lip retraction during the dental procedure.
    The aforementioned oral expansion element may be formed by two portions or pieces, identical and arched, which are coupled in distal, lateral, or alternatively, labial, lateral, areas of the patient's mouth.
    Said member generating a flow of a gaseous fluid is formed by an annular development duct (for example of a plastic or silicone material, among other materials), which can be continuous or discontinuous, which extends along the less a part of the patient's peribucal area, and comprising a plurality of holes arranged substantially in the same plane.
    The annular development conduit in an exemplary embodiment is a tubular element. In this case, the tubular element includes a conduction of annular development, continuous, and also includes a tubular section, in its central area that extends outwards from the patient's mouth, connectable to a suction pump or pressure insufflation of a gaseous fluid (for example air or other neutral gas with an anti-pathogenic chemical agent), or alternatively to one or multiple suction or insufflation sockets available in a dental chair, and one or more tubular sections connectable (s) to a connector of a compressor of a dental box (for example for fluid extraction and / or creation of a pressure).

    Likewise, the suction or pressure insufflation pump may be associated with a flow control means, and a circuit in which said chemical anti-pathogen agent is provided.
    Examples of realization of the present invention also provide according to a second aspect a method for dental procedure. The method comprises using the device of the first aspect of the invention to apply a flow of a gaseous fluid (for example a laminar flow) that exerts a barrier effect between an inner area of a patient's mouth and the outside of the mouth, wherein said flow of a gaseous fluid remains disposed in an area close to a peribucal area of said patient during said dental procedure.
    Examples of realization of the present invention also provide a use of the device of the first aspect of the invention for protection between the patient and a healthcare professional, and vice versa, due to a biological cross-contamination by direct contagion including Flugge microdroplets or microdroplets. produced by a refrigeration spray, or indirectly via contamination of surfaces, clothing or instruments of a dental box.
    Similarly, in other examples of embodiment of the present invention a use of the device of the first aspect of the invention is also provided for a protection between the patient and the healthcare professional, and vice versa, due to a chemical contamination of the chemical type by means of a direct contact or intoxication including suspended particles of dental dust or dental reconstruction material such as resins, amalgams, composites or gases produced by incineration of gutta-percha, or indirect via contamination of surfaces, clothing or instruments of a dental box.
    Also, in still other examples of embodiment, a use of the device of the first aspect of the invention is provided to avoid soaking or wetting by means of water from a dental instrument to the patient's oral cavity including materials, surfaces, tissues and instruments, or even to protect the healthcare professional from halitosis of the patient.

    In the exemplary embodiment of Fig. 5, said tubular element, preferably cylindrical, without being limiting since any tubular material could be used without deviating from the scope of this invention, includes tubular section 15, connectable to one or multiple suction or air insufflation sockets available in a dental chair or, alternatively, a suction or pressure insufflation pump of a gaseous fluid, and two tubular sections 18 intended for the direct aspiration of saliva from the intraoral cavity. Alternatively, the auxiliary device according to this embodiment could include a single tubular section 18 for intraoral saliva aspiration.
    Said suction or pressure insufflation pump of a gaseous fluid is preferably associated with a means of flow control, and a circuit responsible for providing said chemical agent anti-pathogen.
    In other alternative embodiments of the proposed auxiliary device 1, not illustrated by simplicity of the figures, the auxiliary device 1 also includes an illumination system for illuminating the interior of the oral cavity of the patient's mouth during the
    Dental procedure In an exemplary embodiment, said lighting system comprises lighting elements for example of the LED type (light emitting diode) and is powered by batteries included well in the proposed auxiliary device itself well external to it. Alternatively, said lighting system comprises a light wave glutton 5 such as an optical fiber.
    The proposed auxiliary device can come in different sizes and accommodate different shapes and sizes of the mouth.
