Abstract

The present invention provides a dressing with anesthetic effect for use in the oral cavity that comprises a dose of an anesthetic substance for topical use contained, impregnated or embedded in a harmless envelope and/or harmless support that allows the localized release of the anesthetic substance. for topical use. With this dressing the application and release of the anesthetic substance in the oral cavity is achieved in a more localized way than with an anesthetic gel, which is easily spread throughout the mouth. The dressing, having a dose known in advance and being supported or contained or impregnated in an envelope or support, is very suitable to be individually dispensed to patients waiting to be treated in a waiting room and applied by themselves to the area to be treated for exactly five to ten minutes before going to the treatment room. In this way, the treatment time by the dentist is considerably reduced without impairing the tranquility of the patient when receiving the injection of infiltrative anesthetic after having applied a topical local anesthetic because it greatly reduces the acute pain of an injection in the gums.

Apósito oral con efecto anestésicoOral dressing with anesthetic effect

CAMPO TÉCNICO DE LA INVENCIÓNTECHNICAL FIELD OF THE INVENTION

La presente invención pertenece al campo técnico de la práctica médica, en particular de la estomatología, la odontología, la ortodoncia, periodoncia y el tratamiento de afecciones de la boca.The present invention belongs to the technical field of medical practice, in particular stomatology, dentistry, orthodontics, periodontics and the treatment of conditions of the mouth.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Es muy común, sobre todo en niños y niñas, sentir aversión o miedo a acudir al dentista. La principal causa de este miedo es la ansiedad o la aprehensión a recibir el pinchazo en la boca para administrar la anestesia local antes de comenzar el tratamiento en sí.It is very common, especially in boys and girls, to feel aversion or fear to go to the dentist. The main cause of this fear is anxiety or apprehension to receive the prick in the mouth to administer the local anesthesia before starting the treatment itself.

Una forma de disminuir esa ansiedad y la sensación dolorosa causada por el pinchazo del anestésico es la aplicación de un gel con un efecto anestésico suave en la zona de tratamiento, antes de administrar un anestésico infiltrativo más potente con una jeringuilla. Este gel se puede aplicar directamente o impregnado en un algodón. Tras la aplicación del gel, es necesario dejar transcurrir una media de cinco a diez minutos para que se produzca el efecto anestésico del gel antes de poder inyectar el anestésico infiltrativo. Tras la inyección del anestésico infiltrativo, también es necesario dejar transcurrir de cinco a siete minutos antes de comenzar el tratamiento bucal en sí.One way to reduce this anxiety and the painful sensation caused by the injection of the anesthetic is to apply a gel with a mild anesthetic effect to the treatment area, before administering a more powerful infiltrative anesthetic with a syringe. This gel can be applied directly or impregnated on a cotton ball. After the application of the gel, it is necessary to allow an average of five to ten minutes for the anesthetic effect of the gel to take place before the infiltrative anesthetic can be injected. After injection of the infiltrative anesthetic, it is also necessary to allow five to seven minutes to elapse before starting the oral treatment itself.

Sin embargo, la aplicación del gel anestésico, si bien reduce el miedo o ansiedad de los pacientes y se traduce en unas mejores condiciones emocionales para el paciente y el odontólogo para efectuar el tratamiento, también conlleva un tiempo adicional para conseguir su efecto, y esto, reduce considerablemente el número de pacientes que se pueden atender en una jornada. Por dicho motivo, en (mayoría) muchas ocasiones, para conseguir tratar a un mayor número de pacientes, numerosos odontólogos eligen no aplicar el gel anestésico, con lo que, el tratamiento se efectúa con una gran sensación de incomodidad por parte del paciente, y también, del odontólogo por haber causado un dolor muy agudo con la inyección del anestésico infiltrativo.However, the application of the anesthetic gel, although it reduces the fear or anxiety of the patients and translates into better emotional conditions for the patient and the dentist to carry out the treatment, it also takes additional time to achieve its effect, and this , considerably reduces the number of patients that can be attended in a day. For this reason, on (most) many occasions, in order to treat a greater number of patients, Many dentists choose not to apply the anesthetic gel, so the treatment is carried out with a great feeling of discomfort on the part of the patient, and also, of the dentist, for having caused very acute pain with the injection of the infiltrative anesthetic.

DESCRIPCIÓNDESCRIPTION

Descripción resumida de la invenciónSummary description of the invention

Un primer aspecto de la invención aporta un apósito con efecto anestésico para su uso en la cavidad oral que comprende una dosis de una sustancia anestésica de uso tópico contenida, depositada, impregnada o embebida en un envolvente inocuo y/o soporte inocuo que permite la liberación localizada de la sustancia anestésica de uso tópico.A first aspect of the invention provides a dressing with anesthetic effect for use in the oral cavity that comprises a dose of an anesthetic substance for topical use contained, deposited, impregnated or embedded in a harmless envelope and / or harmless support that allows the release localized anesthetic substance for topical use.

Con un apósito como el descrito anteriormente se consiguen varios beneficios. En primer lugar, se consigue la aplicación y liberación de la sustancia anestésica en la cavidad oral de forma más localizada que con un gel anestésico, que fácilmente se esparce por toda la boca debido a su débil consistencia. En segundo lugar, el apósito, al tener una dosis, que es conocida de antemano y estar soportado o contenido o impregnado en una envolvente o soporte, es muy adecuado para ser dispensado individualmente a los pacientes que esperan a ser tratados en una sala de espera, y que, además, ellos mismos pueden aplicarlo en la zona a tratar, exactamente unos cinco o diez minutos antes de pasar a la sala de tratamiento. De esta forma, se puede aplicar la sustancia anestésica localmente por parte de los mismos pacientes sin necesidad de ser aplicada por un odontólogo, con lo que el tiempo total de tratamiento por parte del odontólogo se reduce considerablemente sin menoscabo de la tranquilidad que se ofrece al paciente al recibir la inyección de anestésico infiltrativo una vez que ya se ha aplicado un anestésico que disminuye en gran medida el dolor agudo de una inyección en las encías.With a dressing like the one described above there are several benefits. In the first place, the application and release of the anesthetic substance in the oral cavity is achieved in a more localized way than with an anesthetic gel, which easily spreads throughout the mouth due to its weak consistency. Second, the dressing, by having a dose, which is known in advance and being supported or contained or impregnated in an envelope or support, is very suitable to be individually dispensed to patients waiting to be treated in a waiting room. , and that, in addition, they can apply it themselves in the area to be treated, exactly five or ten minutes before going to the treatment room. In this way, the anesthetic substance can be applied locally by the same patients without having to be applied by a dentist, thus reducing the total treatment time by the dentist considerably without impairing the peace of mind offered to the patient. patient receiving the injection of infiltrative anesthetic after an anesthetic has already been applied which greatly reduces the acute pain of an injection to the gums.

En resumen, el apósito descrito, no solo se permite una aplicación más localizada del anestésico que en el caso del gel, sino que también puede ser auto-administrado tan solo unos minutos antes del tratamiento odontológico por los mismos pacientes, a los cuales les podría ser entregado en mano en recepción, si lo necesitasen.In summary, the dressing described not only allows a more localized application of the anesthetic than in the case of the gel, but it can also be self-administered. just a few minutes before the dental treatment by the patients themselves, to whom it could be delivered by hand at reception, if they needed it.

De forma adicional, el apósito descrito también sirve para conseguir una aplicación más localizada de un anestésico tópico en tratamientos de corta duración en los que no se necesita anestésico infiltrativo, tales como limpiezas dentales, tratamientos periodónticos, retirada de suturas o drenaje de flemones. También puede ser usado para aliviar el dolor de aftas y/o llagas dentales.Additionally, the described dressing also serves to achieve a more localized application of a topical anesthetic in short-term treatments in which infiltrative anesthetic is not required, such as dental cleanings, periodontic treatments, removal of sutures or drainage of phlegmons. It can also be used to relieve pain from canker sores and / or dental sores.

Preferiblemente el apósito está contenido en un envase hermético individual cuyo interior ha sido esterilizado. De esta forma, se evitan riegos de contagio y se consigue una mayor higiene al manipular los apósitos antes de su uso por los pacientes. Contra puesto al formato del gel anestésico, esto es, un envase en tuvo cuyo contenido excede con creces una aplicación mono dosis, llegando incluso a utilizarse el mismo contenido del recipiente en muchos pacientes, un frasco puede ser suficiente para dispensar más de 100 dosis, el apósito descrito se presenta en productos que sólo servirán para ser administrados a un único paciente, minimizando considerablemente, por tanto, cualquier posibilidad de transmitir contagios y/o enfermedades.Preferably the dressing is contained in an individual hermetic container the interior of which has been sterilized. In this way, risks of contagion are avoided and greater hygiene is achieved when handling the dressings before their use by patients. Contrary to the format of the anesthetic gel, that is, a container in had whose content far exceeds a single dose application, even using the same container content in many patients, one bottle may be enough to dispense more than 100 doses, The dressing described is presented in products that will only be used to be administered to a single patient, thus considerably minimizing any possibility of transmitting infections and / or diseases.

La sustancia anestésica de uso tópico puede ser una sustancia anestésica local de baja intensidad y apta para uso oral. Por ejemplo, la sustancia anestésica puede ser benzocaína o lidocaína. Preferiblemente la sustancia anestésica de uso tópico es benzocaína.The anesthetic substance for topical use may be a local anesthetic substance of low intensity and suitable for oral use. For example, the anesthetic substance can be benzocaine or lidocaine. Preferably the anesthetic substance for topical use is benzocaine.

La benzocaína presenta ventajas frente a la lidocaína, ya que exhibe una baja absorción sistémica, es de acción más rápida y tiene una duración de anestesia de 15 a 20 minutos. La benzocaína es un anestésico tópico, indicado para el alivio sintomático de las molestias de la mucosa oral.Benzocaine has advantages over lidocaine, as it exhibits low systemic absorption, is faster acting, and lasts for 15 to 20 minutes of anesthesia. Benzocaine is a topical anesthetic, indicated for the symptomatic relief of discomfort of the oral mucosa.

La dosis de la sustancia anestésica de uso tópico puede estar contenida en una porción de gel. The dose of the anesthetic substance for topical use may be contained in a portion of gel.

La porción de gel puede contener benzocaína al 20 % en peso de concentración.The gel portion may contain benzocaine at a 20% concentration by weight.

La envolvente puede ser una capa de material inocuo semipermeable que permite la liberación de la sustancia anestésica a la cavidad oral al entrar en contacto con saliva.The envelope can be a layer of harmless semi-permeable material that allows the release of the anesthetic substance into the oral cavity on contact with saliva.

El material inocuo semipermeable puede ser una gasa o tejido similar. Alternativamente, el material inocuo semipermeable puede ser un polímero al menos parcialmente degradable por el efecto de la saliva.The harmless semi-permeable material can be gauze or similar fabric. Alternatively, the harmless semi-permeable material may be a polymer that is at least partially degradable by the effect of saliva.

El soporte inocuo puede ser una capa, banda, tira o porción de material sobre o en la cual está depositada, impregnada o embebida la sustancia anestésica de uso tópico. El soporte puede, por tanto, tener diversas formas y configuraciones.The harmless support can be a layer, band, strip or portion of material on or in which the anesthetic substance for topical use is deposited, impregnated or embedded. The support can therefore have various shapes and configurations.

Por ejemplo, el soporte puede ser una tira de material, parecido a una tirita, en la que se ha impregnado la sustancia anestésica de uso tópico. Otro ejemplo es una pasta consistente pero deformable que lleva embebida la sustancia anestésica de uso tópico y que se puede moldear con los dedos o con los dientes y la lengua para darle la forma adecuada y ser alojada en la zona localizada del tratamiento. Otro ejemplo es un soporte sólido en forma de C o arcada o mitad de C o semi arcada, para insertarlo a lo largo de toda o una parte de la alineación de piezas dentales superiores o inferiores.For example, the support can be a strip of material, similar to a plaster, in which the topical anesthetic substance has been impregnated. Another example is a consistent but deformable paste that is embedded with the anesthetic substance for topical use and that can be molded with the fingers or with the teeth and tongue to give it the appropriate shape and be accommodated in the localized area of the treatment. Another example is a solid C-shaped bracket or arch or half C or semi arch, to be inserted along all or a part of the alignment of upper or lower teeth.

El soporte puede comprender un adhesivo para fijar el apósito a una parte de la cavidad oral. Al contar con un adhesivo, el apósito puede ser fijado en la zona local donde el tratamiento debe ser aplicado. Esto es una ventaja sobre todo para aplicar el apósito a niños muy pequeños que todavía no hacen caso de lo que se les dice y que fácilmente escupirían el apósito. Con un adhesivo es más improbable que lo escupan. The backing may comprise an adhesive to secure the dressing to a part of the oral cavity. By having an adhesive, the dressing can be fixed in the local area where the treatment should be applied. This is an advantage especially for applying the dressing to very young children who are still not listening to what they are told and who would easily spit the dressing. With an adhesive they are more unlikely to spit it out.

El adhesivo es apto para uso oral y puede comprender carboximetilcelulosa y/o acetato de polivinilo. El uso de adhesivos en la cavidad oral es conocido para la fijación de dentaduras postizas.The adhesive is suitable for oral use and may comprise carboxymethylcellulose and / or polyvinyl acetate. The use of adhesives in the oral cavity is known for the fixation of dentures.

Se ha de entender que la invención incluye otras muchas formas de realización que incluyen diversas variaciones de las realizaciones aquí descritas y que el ámbito de protección es el definido por las reivindicaciones adjuntas interpretadas según el contenido de la descripción y las Figuras.The following description serves to illustrate the various embodiments of the invention represented in the attached Figures and is provided by way of example only, without intending to constitute a limitation of the scope of protection thereof. It is to be understood that the invention includes many other embodiments that include various variations of the embodiments described herein and that the scope of protection is defined by the appended claims interpreted according to the content of the description and the Figures.

La Figura 1 muestra un apósito con efecto anestésico 1 configurado para su uso en la cavidad oral que comprende una dosis de una sustancia anestésica de uso tópico 2 contenida en una envolvente inocua 3, que en este caso es una envoltura textil sustancialmente de forma cilindrica hecha de gasa tejida estéril en este caso particular, que permite la liberación localizada de la sustancia anestésica de uso tópico, cuando el apósito es colocado en la zona donde se va a administrar una inyección de anestésico infiltrativo u otro tratamiento de corta duración e intensidad, tal como, por ejemplo, una limpieza bucal o la retirada de suturas.Figure 1 shows a dressing with anesthetic effect 1 configured for use in the oral cavity comprising a dose of a topical anesthetic substance 2 contained in a harmless envelope 3, which in this case is a substantially cylindrical textile envelope made of sterile woven gauze in this particular case, which allows localized release of the anesthetic substance for topical use, when the dressing is placed in the area where an injection of infiltrative anesthetic or other treatment of short duration and intensity is to be administered, such as such as, for example, a mouth cleaning or removal of sutures.

La dosis de sustancia anestésica de uso tópico es una dosis de 1.5 gramos de un gel que contiene benzocaína al 20 % en peso y tiene sabor a fruta, a cereza, en este caso, para que el paciente sienta una sensación agradable.The dose of anesthetic substance for topical use is a dose of 1.5 grams of a gel that contains benzocaine at 20% by weight and is fruity, cherry, in this case, so that the patient feels a pleasant sensation.

La gasa tejida estéril está compuesta por dos juegos de hilo de algodón entrecruzados y forman un tejido suave y poroso, que permite la liberación rápida, gradual y contenida del gel en su interior, evitando que el gel se esparza por toda la boca y que el paciente inadvertidamente desparrame el gel por la boca con la lengua. La gasa puede haber sido esterilizada con óxido de etileno.The sterile woven gauze is composed of two sets of interwoven cotton thread and forms a soft and porous fabric, which allows the quick, gradual and contained release of the gel inside, preventing the gel from spreading throughout the mouth and that the patient inadvertently smears gel through mouth with tongue. The gauze may have been sterilized with ethylene oxide.

La Figura 2 muestra el apósito 1 de la Figura 1 envasado en una capsula de material plástico 4 precintada herméticamente con lamina de aluminio 5 y cuyo interior ha sido esterilizado mediante óxido de etileno. El gas óxido de etileno (EtO) se utiliza principalmente para esterilizar productos médicos y farmacéuticos que no soportan la esterilización convencional a alta temperatura, como dispositivos que incorporan componentes electrónicos, envases o recipientes de plástico. El gas EtO se infiltra en los paquetes así como en los propios productos para acabar con los microorganismos que quedan después del proceso de producción o envasado. Figure 2 shows the dressing 1 of Figure 1 packed in a plastic capsule 4 hermetically sealed with aluminum foil 5 and the interior of which has been sterilized by ethylene oxide. Ethylene oxide gas (EtO) is mainly used to sterilize medical and pharmaceutical products that cannot withstand conventional high-temperature sterilization, such as devices that incorporate electronic components, packaging or plastic containers. EtO gas infiltrates the packages as well as the products themselves to kill any microorganisms that remain after the production or packaging process.

Esta forma de realización de la invención es muy apta para ser administrada en mano a los pacientes antes de pasar a la salsa de tratamiento y que tengan la confianza en la higiene del producto para auto-aplicarse el apósito unos minutos antes de empezar el tratamiento o aplicar la inyección de anestésico infiltrativo.This embodiment of the invention is very suitable to be administered by hand to patients before moving on to the treatment sauce and who have confidence in the hygiene of the product to self-apply the dressing a few minutes before starting the treatment or apply injection of infiltrative anesthetic.

En este caso, la dosis de sustancia anestésica es una solución de benzocaína al 25 % en peso (aunque puede ser otra sustancia anestésica de uso tópico de intensidad leve o moderada) que ha sido impregnada o embebida en una lámina absorbente 12 de forma rectangular hecha de algodón y recubierta de una capa porosa de material antiadherente y que está unida a una tira adhesiva de plástico 14, por ejemplo, de polietileno. La tira de polietileno esta provista de un adhesivo oral para sujetar el apósito a la mucosa oral. El apósito está provisto de un recubrimiento de papel adherido a la tira de polietileno que se pela antes de ser aplicado y que sirve de protección del soporte inocuo 12 y del adhesivo. Esta forma de realización de la invención puede ser envasada en sobrecitos individuales, herméticos y esterilizados.Figures 3A and 3B show a dressing 10 with anesthetic effect for use in the oral cavity that comprises a dose of an anesthetic substance for topical use impregnated in a harmless support 12 that allows the localized release of the anesthetic substance for topical use. In this case, the dose of anesthetic substance is a 25% by weight benzocaine solution (although it may be another anesthetic substance for topical use of mild or moderate intensity) that has been impregnated or embedded in an absorbent sheet 12 of rectangular shape made made of cotton and covered with a porous layer of non-stick material and which is attached to an adhesive strip of plastic 14, for example polyethylene. The polyethylene strip is provided with an oral adhesive to hold the dressing to the oral mucosa. The dressing is provided with a paper coating adhered to the polyethylene strip which is peeled off before being applied and which serves to protect the harmless backing 12 and the adhesive.
