    ORAL PROTECTOR DEVICE WITH LINGUAL DEPRESSOR
    DESCRIPTION
    5 OBJECT OF THE INVENTION
    The present invention falls within the technical field of the instruments to proceed to the medical examination through the mouth that have a tongue depressor, as well as that of the devices to act on the respiratory system of the patients 10 by means of a gas-based treatment, and refers in particular to a device for the protection of lips and teeth of a patient undergoing examination or intervention through the oral cavity, which incorporates a tongue depressor.
    BACKGROUND OF THE INVENTION
    fifteen
    In routine clinical practice there are various interventions and diagnostic tests, such as endoscopy, fibrobronchoscopy, transesophageal ultrasound, etc., in which it is necessary to introduce different instruments, both in the digestive tract and in the airway, through from the patient's mouth. To this end, numerous devices are known in the state of the art, which are usually limited to protecting the medical material introduced into the mouth and, to a lesser extent, the dentures of the patients.
    It is also usual that during the performance of these diagnostic tests it is necessary to use sedation for a better tolerance of the procedure, which inhibits and hinders the normal respiration of the patients, largely due to the depressing effect that the drugs exert on the Oropharyngeal and lingual musculature. The usual mouthguards, when inserted into the patient's mouth, move the tongue towards the back, so that it protrudes and hinders both the correct ventilation of the patient and the maneuver of introducing the exploratory material in question from the oral cavity to the digestive tract or the lower airway.
    On the other hand, one of the main reasons for claiming in patients who have undergone anesthesia is derived from the breakage of teeth by the use of
    laryngoscopy for the orotracheal intubation necessary for the installation of mechanical or assisted ventilation for any type of general anesthesia, since there is no systematic use of protective measures to avoid such breaks. In addition, the increased morbidity and mortality of general anesthesia is associated with complications related to difficult access to the airways in certain patients.
    DESCRIPTION OF THE INVENTION
    The object of the invention is a mouth guard that incorporates a
    10 lingual depressant, intended to enter the patient's mouth and keep it open during diagnostic tests or surgical interventions that require the introduction of instruments through the oral cavity, which avoids the problems described above.
    15 To this end, the device comprises firstly two structures, preferably made of soft consistency materials, designed to define an access to the patient's oral cavity by separating the jaws, while protecting the lips and the denture. To this end, it covers them by means of sheath type pieces with a shape similar to the dental arch and a thickness such that it allows it to cover from the
    20 outer face of the lips to the inner surface of the teeth. A first cover protects both the lip and the arch of teeth corresponding to the upper part of the mouth, while a second cover is intended to protect the lip and the arch of teeth from the lower part.
    25 Said first and second covers have standardized dimensions to the usual for the mouth of an adult user, but can be made in any size, including the pediatric, and additionally comprise lateral extensions to also protect the rows of premolars and molars both in the mandible or lower jaw as in the upper jaw.
    30
    Both covers are articulated with each other by means of a mechanism, preferably of the cogwheel type, which regulates the degree of separation between them and, therefore, the degree of opening of the oral cavity, so that, once the separation between is achieved jaws needed to define sufficient access for the
    Exploration or intervention instruments access the inside of the mouth, block said opening by fixing the articulation of the structures in the patient's mouth so that they do not close it, thus reducing the risk of injury.
    5 In an alternative embodiment, the mechanism that regulates the degree of separation between sleeves consists of a serrated saw-like structure practiced at the rear lateral ends of the second sheath, to which oscillating flanges practiced at the corresponding posterior lateral ends of The first case.
    10 On the other hand, the second sheath, designed to protect the lip and the arch of lower teeth, has a groove-shaped through opening in the center of its front part, sized to introduce a semi-rigid lingual depressor through it, which, exceeding the upper part of the second sheath that protects the lip and the arcade of teeth of the jaw, and following the curvature of the tongue, advances towards the pharynx 15 of the patient, being able to reach the epiglottic valley, depressing in turn the tongue so that it does not obstruct the oral cavity or the oropharynx and, therefore, does not hinder the patient's breathing. Said depressant thus favors the introduction of diagnostic instruments of different types, such as endoscopes, fibrobronchoscopes, probes, and even a laryngoscope, reducing the risk of obstructing the airway. The groove also allows anchoring of the tongue depressor once its desired level of depression is achieved, leaving it fixed and thus facilitating the operations to be performed.
    Each of the protectors, lower and upper, can be fitted with an adjustable rubber band or tape that joins the rear lateral ends of each protector surrounding the back of the head, thereby helping the stabilization of the device and preventing mobilization. desired of the same.
    The device thus described, therefore consisting essentially of a dental and labial protector 30 that incorporates a mouth opening and tongue depressor system, thus solves the main problems derived from the explorations and interventions performed through the mouth, since :
    - Avoid protrusion of the tongue, or displacement of the tongue against the
    5
    10
    fifteen
    twenty
    25
    teeth, thanks to the anchoring of the lingual depressant, before diagnostic and therapeutic tests, as well as its posterior fall towards the oropharynx due to the effects of anesthetic drugs and the instruments introduced.
    - Maximizes the oral opening before the need to introduce devices, which allows easy access to the oropharyngeal cavity and allows the introduction of instruments such as endoscopes, fibrobronchoscopes, probes of different application and even laryngoscopes, minimizing damage to the oral and pharyngeal level.
    - Improves spontaneous ventilation through the oral cavity, and protects teeth and lips.
    All this thanks to a simple device to place and remove from the patient's mouth, which also avoids the usual discomforts of remaining with the mouth open for prolonged periods of time. On the other hand, it is designed for a single use, so it is preferably made of economical and easily disposable and recyclable materials such as low density polyethylene or flexible polyvinylchloride, so in addition to comfortable, this device is hygienic and safe for the patient .
    DESCRIPTION OF THE DRAWINGS
    To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of the same, a set of drawings is accompanied as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:

    PREFERRED EMBODIMENT OF THE INVENTION
    10 Next, a detailed explanation of an example of preferred embodiment of the object of the present invention is provided with the aid of the aforementioned figures.
    As can be seen in Figure 1, the oral protective device with tongue depressor 15 described below basically comprises a first sheath (1) and a second sheath (2), joined and articulated together by means of an opening regulating mechanism and blockage (3), which are introduced into the patient's mouth. Both the first cover (1) and the second cover (2) have the shape, similar to an arch, and the dimensions necessary to cover the patient's lips and dental arches; The first cover (1) 20 covers the upper lip and the arch of the teeth of the upper jaw, while the second cover (2) covers the lower lip and the arch of teeth of the mandible or lower jaw.
    The opening and locking regulating mechanism (3), located on the sides of the 25 rear ends of the first sheath (1) and the second sheath (2), creates an articulated joint between both sleeves, thereby also regulating the degree opening of the oral cavity by separating the upper and lower jaws. Once said jaws have been separated, defining an access opening to the oral cavity with the appropriate dimensions for the introduction of the necessary instruments, the opening and locking regulating mechanism (3) fixes said separation between first sheath (1) and second case (2), thus preventing the closure of the jaws. In a preferred embodiment as shown in Figure 1, said opening and locking regulating mechanism (3) comprises a gearwheel, in which each turn defines a degree of separation between the first sheath (1) and the second sheath (2) until, once
    Once the necessary opening of the mouth is reached, the rotation of said wheel is blocked, thus fixing the separation between jaws.
    As shown in Figures 1, 2 and 3, the second sheath (2) additionally comprises a groove (4), preferably made in the center of its front face and through into the oral cavity, through the which introduces a semi-rigid lingual depressant (5) and with a degree of curvature at its initial end appropriate to the lingual and pharyngeal anatomy that, exceeding the upper part of the lower lip and the jaw teeth arch, as detailed in Figure 3, follows the curvature of the tongue and 10 advances towards the oropharynx, which is the anatomical region that includes the posterior third of the tongue and extends from the soft palate to the hyoid, and can even reach the need epiglottic vallecula. The groove (4) allows the anchoring of the tongue depressor (5) once it is arranged in the desired position of depression and immobilization of the tongue, fixing it without the need of restraint by the healthcare professional 15 and thus facilitating exploration operations.
    Both the first sheath (1) and the second sheath (2) additionally comprise lateral extensions (6) to cover and protect the row of molar and premolar teeth of both the upper and lower jaw, as well as, optionally, a tape (7) or adjustable rubber made of flexible material that joins the respective rear ends of the first case (1) and the second case (2) surrounding the back of the patient's head, as shown in the figure 4, thereby stabilizing the device and ensuring its immobility.
    25 The first case (1), the second case (2) and its lateral extensions (6), are made of disposable materials of soft consistency that cover without damaging the patient's lips and teeth; In a preferred embodiment, said material is low density polyethylene which, in addition, can carry a silicone coating in the areas that are in direct contact with the most fragile parts, such as the lips and the endas.
    The oral protective device with tongue depressor thus described is a hygienic, safe and simple device to place and remove from the patient's mouth, which avoids the usual discomforts of staying with the mouth open and protects the lips and lips.
    teeth of the damages that usually occur during the explorations and interventions carried out through the oral cavity. In addition, in the case of those patients who must undergo sedation, avoid the efforts of the professional staff involved to maintain the necessary openness.
