OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un artículo absorbente para incontinencia con indicador de saturación que tiene aplicación en el ámbito de Ia industria dedicada a Ia producción de productos absorbentes para incontinencia, y en particular para pérdidas de orina producidas como consecuencia de afecciones de incontinencia urinaria, permitiendo evitar fugas o escapes mediante un indicador visual que indica cuando es necesario reemplazar el artículo por otro nuevo de manera previa a que se produzca una fuga, debido a que el artículo se encuentra en un nivel de saturación previo a que se produzca un escape de flujo a absorber hacia una zona exterior del artículo.The present invention relates to an absorbent article for incontinence with saturation indicator that has application in the field of the industry dedicated to the production of absorbent products for incontinence, and in particular for urine losses produced as a result of urinary incontinence conditions, allowing to avoid leaks or leaks by means of a visual indicator that indicates when it is necessary to replace the article with a new one before a leak occurs, because the article is at a saturation level prior to the escape of flow to be absorbed towards an outside area of the article.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
La incontinencia urinaria supone un trastorno en los hábitos diarios de las personas que padecen dicha afección, que actualmente afecta a un considerable número de personas y que se manifiesta sobre todo en Ia madurez, y en particular de manera mayoritaria en Ia población femenina.Urinary incontinence involves a disorder in the daily habits of people who suffer from this condition, which currently affects a considerable number of people and which manifests itself especially in maturity, and in particular mostly in the female population.
La incontinencia urinaria tiene como consecuencia, que el aparato urinario pierda de manera parcial o total su función de control, con Io que se producen fugas o escapes de orina de manera no deseada, llegando a producirse e incluso una falta total de control sobre dicha función, con el consiguiente trastorno para Ia persona que padece esta afección, mayoritariamente personas de edad madura que en algunos casos requieren cuidados y atenciones para Ia realización de tareas cotidianas, teniendo como consecuencias una desagradable sensación de humedad y malos olores.The urinary incontinence has, as a consequence, that the urinary system partially or totally loses its control function, resulting in unwanted leakage or leakage of urine, leading to occur and even a total lack of control over said function. , with the consequent disorder for the person suffering from this condition, mostly people of mature age than in some cases They require care and attention to perform daily tasks, resulting in an unpleasant sensation of moisture and bad odors.
En Ia actualidad, con el objeto de paliar y mejorar las condiciones de vida de las personas que padecen incontinencia urinaria, son conocidos diferentes productos absorbentes desechables cuya estructura básica consta de un cuerpo absorbente que por su parte superior tiene una capa compuesta por un material tejido no tejido, y por su parte inferior tienen una capa aislante de polietileno, que a su vez puede estar exteriormente recubierta por otra capa de material tejido no tejido con el objeto de proporcionar a Ia superficie externa del producto absorbente un aspecto estético atractivo que imita un material textil y que resulta agradable al tacto.At present, in order to alleviate and improve the living conditions of people suffering from urinary incontinence, different disposable absorbent products are known whose basic structure consists of an absorbent body that has a layer composed of a woven material nonwoven, and on the lower part they have an insulating layer of polyethylene, which in turn can be externally covered by another layer of nonwoven woven material in order to provide the external surface of the absorbent product with an attractive aesthetic appearance that mimics a textile material and that is pleasant to the touch.
Sobre todo en el caso de que los pacientes y usuarios de estos productos se encuentren incapacitados para Ia utilización autónoma por sí solos de estos productos absorbentes, para cuyo cambio requieren de Ia ayuda de personal apto para retirar y reemplazar los productos utilizados por otros nuevos, existen productos que comprenden medios indicadores del nivel de humedad del mismo, de forma que no es necesario su retirada paraEspecially in the event that patients and users of these products are incapacitated for the autonomous use of these absorbent products alone, for which change they require the help of qualified personnel to remove and replace the products used with new ones, there are products that include means indicating the humidity level of the same, so that its removal is not necessary to
Ia comprobación de necesidad de retirar el producto, permitiendo identificar tal situación de manera rápida.The need check to remove the product, allowing to identify such situation quickly.
En estos casos los productos tienen situado, sobre Ia capa de material impermeable, Io que se denomina un indicador de humedad o indicador de nivel de saturación del producto, que está constituido por diversos medios indicadores, si bien todos ellos cumplen Ia misma función, es decir permitir identificar el instante en el que se requiere reemplazar o cambiar el producto absorbente, debido a su saturación de flujo a absorber, habitualmente orina. En algunos productos dichos medios indicadores de humedad consisten en líneas de cola de color amarillo, de grosores diversos, situadas de manera paralela entre sí en el centro del producto según una dirección longitudinal del mismo, considerando que dicha dirección longitudinal se corresponde con Ia dirección de Ia dimensión más alargada del producto dada su configuración para su utilización en Ia zona de Ia entrepierna.In these cases the products have located, on the layer of impermeable material, what is called a moisture indicator or saturation level indicator of the product, which is constituted by various indicator means, although they all fulfill the same function, it is say allow to identify the moment in which it is required to replace or change the absorbent product, due to its saturation of flow to be absorbed, usually urine. In some products, said moisture indicator means consist of yellow tail lines, of varying thicknesses, located parallel to each other in the center of the product according to a longitudinal direction thereof, considering that said longitudinal direction corresponds to the direction of The elongated dimension of the product given its configuration for use in the crotch area.
Estos indicadores están configurados para cambiar de color, es decir para transformar de manera paulatina su color amarillo por un color azul intenso cuando están en contacto con el flujo a absorber, habitualmente orina, de acuerdo con su composición química que está configurada para reaccionar con dicho flujo a absorber cuando entran en contacto.These indicators are configured to change color, that is, to gradually transform their yellow color to an intense blue color when they are in contact with the flow to be absorbed, usually urine, according to their chemical composition that is configured to react with said flow to absorb when they come into contact.
Asimismo son igualmente conocidos indicadores de humedad que consisten en bandas de tinta que están posicionadas longitudinalmente a Io largo de Ia parte central del producto o bien transversalmente en Ia parte anterior y posterior del mismo, de forma que cuando Ia orina entra en contacto con Ia tinta, dicha tinta desaparece, permitiendo así advertir externamente por parte de una persona distinta del usuario del producto, sin Ia necesidad de retirar el producto, conocer si el producto requiere ser cambiado o no.Likewise, moisture indicators are also known, which consist of ink bands that are positioned longitudinally along the central part of the product or transversely in the front and back of the product, so that when the urine comes into contact with the ink , said ink disappears, thus allowing externally warn by a person other than the user of the product, without the need to remove the product, know if the product needs to be changed or not.
Por otro lado es un hecho conocido y comprobado que durante Ia utilización de productos absorbentes, Ia práctica totalidad de los escapes de flujo a absorber se produce por los laterales del producto, concretamente enOn the other hand, it is a known and proven fact that during the use of absorbent products, almost all of the flow leaks to be absorbed are produced by the sides of the product, specifically in
Ia mayoría de los casos en Ia parte trasera del mismo, por efecto de difusión de Ia orina por el núcleo absorbente que es atravesado por fenómeno de capilaridad, superando incluso barreras laterales de contención, por debajo de las mismas, en aquellos casos en los que el producto absorbente dispone de ellas. El principal inconveniente que presentan los productos absorbentes existentes en Ia actualidad que incorporan los anteriormente referidos medios indicadores del nivel de humedad, consistentes en bandas longitudinales que cambian de color cuando el producto ha sido usado y el núcleo absorbente ha absorbido un determinado flujo de orina, es que dichos medios indicadores de humedad están dispuestos en Ia zona central del producto, que es una zona por Ia que no se producen las fugas de orina hacia el exterior del producto absorbente, las cuales se producen precisamente por los laterales de Ia zona de Ia entrepierna. ,The majority of the cases in the back part thereof, due to the diffusion effect of the urine through the absorbent core that is crossed by capillary phenomenon, even overcoming lateral containment barriers, below them, in those cases in which the absorbent product has them. The main drawback presented by the absorbent products currently present that incorporate the aforementioned moisture level indicator means, consisting of longitudinal bands that change color when the product has been used and the absorbent core has absorbed a certain urine flow, is that said humidity indicator means are arranged in the central area of the product, which is an area where urine leaks outside the absorbent product do not occur, which are produced precisely by the sides of the area of the Ia crotch. ,
La consecuencia de este inconveniente es que en un gran número de ocasiones se producen escapes de orina hacía el exterior, que no son detectados por los medios indicadores de humedad, puesto que a menudo Ia celulosa interior que forma el núcleo absorbente dicha zona central, o bien Ia zona extrema de los medios indicadores, no han sido aún empapadas o impregnadas suficientemente con orina, mientras que en cambio los laterales del producto sí han sido empapados, produciéndose fugas, incluso en caso de que el producto comprenda barreras laterales, sin que se produzca ninguna advertencia, aviso o cambio en los medios indicadores de humedad, no delatan Ia necesidad de cambiar el producto absorbente cuando dicha necesidad sí existe.The consequence of this inconvenience is that on a large number of occasions urine leaks to the outside are produced, which are not detected by the humidity indicating means, since often the inner cellulose that forms the absorbent core said central area, or either, the extreme zone of the indicator means has not yet been soaked or impregnated sufficiently with urine, while instead the sides of the product have been soaked, causing leaks, even if the product comprises side barriers, without being Produce any warning, warning or change in the humidity indicator means, they do not betray the need to change the absorbent product when said need does exist.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
La presente invención se refiere a un artículo absorbente para incontinencia con indicador de saturación, preferentemente para incontinencia urinaria aunque también puede ser utilizado para Ia absorción de flujo corporal, que permite evitar que se produzcan fugas o escapes mediante un indicador visual que indica cuando es necesario reemplazar el artículo por otro nuevo de manera previa a que se produzca una fuga, debido a que el artículo se encuentra en un nivel de saturación previo a que se produzca un escape de flujo a absorber hacia una zona exterior del artículo, en el caso de que el artículo continúe siendo usado.The present invention refers to an absorbent article for incontinence with saturation indicator, preferably for urinary incontinence although it can also be used for the absorption of body flow, which allows to avoid leaks or leaks by means of a visual indicator that indicates when it is necessary replace the item with a new one before a leak occurs, because the item is at a saturation level before there is a leakage of flow to be absorbed towards an outside area of the article, in the event that the article continues to be used.
El artículo absorbente desechable para incontinencia urinaria con indicador de saturación comprende una capa superior que es una lámina permeable a los líquidos de material tejido no tejido hidrófilo y que está situada en una zona o capa extrema interior del artículo, es decir en contacto con Ia piel del usuario en Ia zona de Ia entrepierna.The disposable absorbent article for urinary incontinence with saturation indicator comprises a top layer that is a liquid permeable sheet of hydrophilic nonwoven material and that is located in an inner end zone or layer of the article, that is to say in contact with the skin of the user in the crotch area.
Por otro lado el artículo absorbente comprende un núcleo o cuerpo absorbente que está situado debajo de Ia capa superior, siendo el elemento principal del artículo destinado a Ia absorción del flujo, es decir de las fugas de orina.On the other hand, the absorbent article comprises an absorbent core or body that is located below the upper layer, the main element of the article being destined for the absorption of the flow, that is to say of urine leaks.
Asimismo el artículo comprende una capa inferior que es una lámina de material impermeable, es decir un material hidrófobo, preferentemente polietileno, que está situada debajo del cuerpo absorbente y actúa como aislante del flujo, siendo esta capa inferior Ia que está destinada a estar en contacto, o al menos en proximidad, con Ia prenda interior del usuario, evitando así que el flujo a absorber pueda calar a Ia ropa del paciente al salir del artículo absorbente.Likewise, the article comprises a lower layer that is a sheet of impermeable material, that is to say a hydrophobic material, preferably polyethylene, which is located under the absorbent body and acts as an insulator of the flow, this lower layer being that which is intended to be in contact , or at least in proximity, with the wearer's undergarment, thus preventing the flow to be absorbed from being able to penetrate the patient's clothing upon exiting the absorbent article.
Con el objeto de atender al efecto estético del artículo, y hacerlo más atractivo para el usuario, o bien para una mejor combinación con Ia ropa que use el paciente, se contempla Ia posibilidad de que esta capa inferior sea de diferentes colores, incluyendo el blanco, permitiendo así un mejor camuflaje del artículo, contemplándose igualmente Ia posibilidad de que una cara inferior de dicha capa inferior, es decir Ia cara externa del artículo opuesta a Ia de contacto con el usuario, tenga impresos motivos diversos. De acuerdo con Ia invención el artículo comprende al menos dos indicadores de saturación, que son marcas indicadoras de nivel de saturación de humedad, que pueden tener configuración de banda, estando situados dichos indicadores longitudinalmente en una cara inferior de Ia capa inferior que resulta visible cuando el artículo está colocado en una posición de uso.In order to meet the aesthetic effect of the article, and make it more attractive to the user, or for a better combination with the clothes worn by the patient, the possibility that this lower layer is of different colors, including white, is contemplated , thus allowing a better camouflage of the article, also contemplating the possibility that a lower face of said lower layer, that is to say the external face of the article opposite to that of contact with the user, has various motifs printed. In accordance with the invention, the article comprises at least two saturation indicators, which are indicative marks of humidity saturation level, which may have a band configuration, said indicators being located longitudinally on a lower face of the lower layer that is visible when The item is placed in a position of use.
Los indicadores de saturación están dispuestos en correspondencia, es decir en una misma zona y en paralelo con dos barreras laterales, que comprende el artículo, situadas en Ia capa superior.The saturation indicators are arranged in correspondence, that is to say in the same area and in parallel with two lateral barriers, which the article comprises, located in the upper layer.
Cada barrera lateral está situada en un lateral del artículo, estando configuradas para estar en contacto directo con el usuario, por Io que cada barrera lateral tiene dispuesto en correspondencia al menos un indicador de saturación, por Ia cara opuesta a Ia capa superior, es decir por Ia capa inferior.Each side barrier is located on one side of the article, being configured to be in direct contact with the user, so that each side barrier has at least one saturation indicator, corresponding to the face opposite the upper layer, that is to say by the lower layer.
Las barreras laterales actúan como medios antiescape o diques de contención, y son de material tejido no tejido hidrófobo, transpirable y suave, estando configuradas para contener el flujo a absorber e impedir fugas de dicho flujo provenientes del cuerpo absorbente por Ia parte lateral del artículo.The side barriers act as anti-escape means or containment dikes, and are made of hydrophobic, breathable and soft nonwoven woven material, being configured to contain the flow to be absorbed and prevent leakage of said flow from the absorbent body through the lateral part of the article.
