Dispositivo para la desinfección de prendas de vestir Garment disinfection device
CAMPO TÉCNICO TECHNICAL FIELD
La presente invención se refiere un dispositivo capaz de inactivar en un inferior a 60 segundos microorganismos como bacterias, virus y protozoos mediante radiación UV en prendas de vestir, y más particularmente a un dispositivo que puede ser instalado en establecimientos de venta de ropa, al objeto de que las prendas sean desinfectadas a alta velocidad tras ser manipuladas en los probadores o en el momento de la compra, de manera que el usuario tenga la certeza que adquiere una prenda en óptimas condiciones de higiene sin necesidad de esperas. The present invention refers to a device capable of inactivating microorganisms such as bacteria, viruses and protozoa in less than 60 seconds by means of UV radiation in clothing, and more particularly to a device that can be installed in clothing stores, to the object that the garments are disinfected at high speed after being manipulated in the changing rooms or at the time of purchase, so that the user is sure that they acquire a garment in optimal hygienic conditions without the need to wait.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
La luz Ultravioleta es un tipo de radiación electromagnética. Se trata de una luz invisible para el ser humano al estar su longitud de onda por encima del espectro visible. Dicha longitud de onda se encuentra entre los 100 y los 400 nanómetros. Este rango de energía electromagnética puede a su vez subdividirse en las siguientes bandas (UV/UV-C/UV-B y UV-A). Ultraviolet light is a type of electromagnetic radiation. It is an invisible light for humans as its wavelength is above the visible spectrum. This wavelength is between 100 and 400 nanometers. This range of electromagnetic energy can in turn be subdivided into the following bands (UV / UV-C / UV-B and UV-A).
El Ultravioleta germicida UVG se refiere a la luz ultravioleta de longitud de onda corta que resulta eficaz en la eliminación de las bacterias y esporas e inactiva los virus. Las longitudes de onda en Ultravioleta conocida como «UV-C», de 200 a 280 nanómetros (nm), han demostrado ser las más efectivas para la desinfección, aunque los rayos UV más largos y menos energéticos también pueden desinfectar si se aplican en dosis mucho mayores. Germicidal UVG refers to short wavelength ultraviolet light that is effective in killing bacteria and spores and inactivating viruses. The wavelengths in Ultraviolet known as "UV-C", from 200 to 280 nanometers (nm), have been shown to be the most effective for disinfection, although longer and less energetic UV rays can also disinfect if applied in doses. much older.
La energía radiante de UVG provoca desajustes y daños en los ácidos nucleicos (ADN y ARN) del microorganismo, causando mutaciones que impiden su reproducción, lo que provoca la muerte de prácticamente todas las bacterias y la inactivación de todos los virus, tanto ADN como ARN. The radiant energy of UVG causes mismatches and damage to the nucleic acids (DNA and RNA) of the microorganism, causing mutations that prevent their reproduction, which causes the death of practically all bacteria and the inactivation of all viruses, both DNA and RNA .
Por tal motivo, la radiación UV-C es utilizada comercialmente como medio germicida y desinfectante. For this reason, UV-C radiation is used commercially as a germicidal and disinfectant medium.
Los factores clave para la utilización como medio germicida de la radiación UV-C son intensidad de radiación y dosis de Ultravioleta. The key factors for the use as a germicidal medium for UV-C radiation are radiation intensity and UV dose.
La dosis UV (energía por unidad de área) es el producto de la intensidad de UV (potencia por unidad de área) por el tiempo de exposición (expresado en segundos), siendo su The UV dose (energy per unit area) is the product of the UV intensity (power per unit area) and the exposure time (expressed in seconds), being its
HOJA DE REEMPLAZO (REGLA 26) expresión: SUBSTITUTE SHEET (RULE 26) expression:
Dosis UV (mJ/cm2) = I (mW/cm2) x T (seg) UV dose (mJ / cm2) = I (mW / cm2) x T (sec)
10 J/m2 = 1 mJ/cm2 10 J / m2 = 1 mJ / cm2
Así pues, la distancia de la lámpara UV-C al elemento a desinfectar es decisiva para calcular el tiempo de exposición necesario para alcanzar la dosis que garantice la inactivación de los microorganismos. Thus, the distance from the UV-C lamp to the element to be disinfected is decisive in calculating the exposure time necessary to reach the dose that guarantees the inactivation of the microorganisms.
La siguiente tabla realizada a partir de datos empíricos muestra la disminución de la irradiancia en función de la distancia:

The following table made from empirical data shows the decrease in irradiance as a function of distance:

A nivel informativo, cabe destacar que, empíricamente se ha determinado que la dosis efectiva para reducir el 90% de la carga de coronavirus se sitúa entre 7 a 241 J/m2, sin embargo, las dosis aplicativas varían logarítmicamente al incrementar la reducción de carga viral. Por ejemplo, para acercarse a un 99% la dosis puede llegar a ser cuatro veces superior. También la dosis aplicativa varía notablemente en función del microorganismo a eliminar.At an informative level, it should be noted that, empirically, it has been determined that the effective dose to reduce 90% of the coronavirus load is between 7 to 241 J / m2, however, the application doses vary logarithmically as the load reduction increases. viral. For example, to approach 99% the dose can be four times higher. Also the application dose varies remarkably depending on the microorganism to be eliminated.
Uno de los usos más comunes de los UV-C es la esterilización y desinfección de aire y agua para lo cual se utilizan lámparas UV-C estratégicamente dispuestas en depósitos y canalizaciones. One of the most common uses of UV-C is the sterilization and disinfection of air and water, for which UV-C lamps strategically placed in tanks and pipes are used.
Un ejemplo de este tipo de uso se describe en la patente US3975790 donde una lámpara ultravioleta es utilizada en combinación con un sistema de filtración convencional con el propósito de purificar el aire dentro de una habitación. An example of this type of use is described in patent US3975790 where an ultraviolet lamp is used in combination with a conventional filtration system for the purpose of purifying the air inside a room.
HOJA DE REEMPLAZO (REGLA 26) También se han descrito aplicaciones de UV-C para la esterilización y desinfección de elementos textiles consistentes en lámparas de mano y dispositivos de aspiración que incorporan lámparas UV. SUBSTITUTE SHEET (RULE 26) UV-C applications have also been described for the sterilization and disinfection of textile elements consisting of hand lamps and suction devices incorporating UV lamps.
La patente US4907316 describe una aspiradora para desinfectar cortinas, alfombras y similares que presenta en la boquilla de aspiración un emisor UV que emite una radiación de acción desinfectante. Patent US4907316 describes a vacuum cleaner for disinfecting curtains, carpets and the like that has a UV emitter on the suction nozzle that emits radiation with a disinfecting action.
La patente EP1879491 describe un esterilizador para ropa de cama capaz de moverse sobre el objeto a limpiar para matar bacterias e insectos dañinos que habitan en su superficie y retirarlos una vez muertos. Para ello incluye un medio emisor de luz UV que mata insectos e inactiva virus y bacterias, así como medios de succión que retiran por aspiración los insectos muertos, los cuales son retenidos en una unidad de filtro instalada en un paso de aire. Patent EP1879491 describes a sterilizer for bedding capable of moving over the object to be cleaned to kill bacteria and harmful insects that inhabit its surface and remove them once dead. For this, it includes a UV light emitting medium that kills insects and inactivates viruses and bacteria, as well as suction means that remove dead insects by aspiration, which are retained in a filter unit installed in an air passage.
Estos dispositivos no son adecuados para desinfectar prendas de ropa tales como chaquetas, blusas, camisas o pantalones ya que los medios de aspiración tienden a atascarse con el tejido tratado. These devices are not suitable for disinfecting garments such as jackets, blouses, shirts or pants as the suction means tend to get clogged with the treated fabric.
Por otro lado, la desinfección con lámparas de mano resulta lenta y dificultosa al ser necesario recorrer manualmente la superficie de las prendas. Por otro lado, como no cuentan con ningún tipo de protección contra la radiación, son equipos de muy baja irradiancia, de manera que para que las desinfecciones resulten efectivas, el tiempo de exposición debe ser muy elevado corriéndose el riesgo de tener una falsa seguridad en su efectividad. On the other hand, disinfection with hand lamps is slow and difficult as it is necessary to manually go over the surface of the garments. On the other hand, as they do not have any type of protection against radiation, they are equipment with very low irradiance, so that for disinfections to be effective, the exposure time must be very high, running the risk of having a false safety in its effectiveness.
Por ejemplo, un equipo cuyas características técnicas indiquen una irradiancia de 8 mW/cm2 a 5 cm de la superficie a tratar, necesitará del orden de 3/4 segundos para alcanzar la dosis UV de 30 mJ/cm2. En cambio, si alejamos la misma lámpara unos 50 cm de la superficie, la irradiancia bajará hasta los 0,080 mW/cm2 y, por tanto, el tiempo de exposición debiera aumentar hasta los 275 segundos. For example, a device whose technical characteristics indicate an irradiance of 8 mW / cm2 at 5 cm from the surface to be treated, will need about 3/4 seconds to reach the UV dose of 30 mJ / cm2. On the other hand, if we move the same lamp about 50 cm from the surface, the irradiance will drop to 0.080 mW / cm2 and, therefore, the exposure time should increase to 275 seconds.
Por otro lado, la exposición a la luz UV-C es altamente perjudicial para la piel y los ojos siendo necesario tener ciertos conocimientos y entrenamiento, así como utilizar equipos de protección individual (EPIs) adecuados para manejar lámparas de mano. On the other hand, exposure to UV-C light is highly damaging to the skin and eyes, making it necessary to have certain knowledge and training, as well as to use appropriate personal protective equipment (PPE) to handle hand lamps.
Por lo expuesto, la operación de descontaminación de prendas de ropa es complicada, laboriosa y no exenta de peligro. Therefore, the decontamination of clothing is complicated, laborious and not without danger.
No se ha descrito ningún dispositivo capaz de inactivar bacterias, virus y protozoos en No device capable of inactivating bacteria, viruses and protozoa has been described in
HOJA DE REEMPLAZO (REGLA 26) prendas de vestir de una manera rápida y automatizada, el cual pueda ser instalado y utilizado en un establecimiento de venta de ropa por personal no especializado en desinfección de microorganismos con total efectividad y seguridad. SUBSTITUTE SHEET (RULE 26) garments in a fast and automated way, which can be installed and used in a clothing store by personnel not specialized in disinfection of microorganisms with total effectiveness and safety.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
La presente invención se refiere a un dispositivo para la desinfección de prendas de vestir que solventa los problemas descritos en el apartado anterior ya que es un aparato capaz de irradiar de forma automatizada y muy efectiva con UV-C todo tipo de prendas de vestir, de manera que en menos de sesenta segundos puede realizar una higienización en la que otros dispositivos invertirían varios minutos. The present invention refers to a device for the disinfection of clothing that solves the problems described in the previous section since it is an apparatus capable of automatically and very effectively irradiating with UV-C all types of clothing, of So in less than sixty seconds you can perform a sanitization in which other devices would spend several minutes.

La invención parte de la premisa que la radiación UV, en un punto, es inversamente proporcional al cuadrado de la distancia que hay entre la lámpara y dicho punto, siendo su expresión matemática (10/11 =d12/d02). The invention starts from the premise that UV radiation, at a point, is inversely proportional to the square of the distance between the lamp and said point, its mathematical expression being (10/11 = d12 / d02).
Por lo tanto, cuanto más cerca del foco sea posicionado el elemento a desinfectar, más rápidamente se alcanzará la dosis letal de radiación UV. Therefore, the closer to the focus the item to be disinfected is positioned, the faster the lethal dose of UV radiation will be reached.
Concretamente, el nuevo dispositivo comprende un cuerpo rectangular dotado de una base para colocarlo sobre el suelo, un mueble o una peana, que presenta en su cara frontal una puerta de acceso y cuyo interior presenta uno o más compartimentos verticales de entre 15 y 30 cm de ancho, separados por tabiques conformados por una pluralidad de lámparas UV-C en cada caso. Cada compartimento presenta en su parte superior un soporte donde se cuelga la prenda a tratar con la ayuda de una percha. Specifically, the new device comprises a rectangular body equipped with a base to place it on the floor, a piece of furniture or a pedestal, which has an access door on its front face and the interior of which has one or more vertical compartments of between 15 and 30 cm. wide, separated by partitions made up of a plurality of UV-C lamps in each case. Each compartment has a support in its upper part where the garment to be treated is hung with the help of a hanger.
De esta forma, las prendas se mantienen a una distancia de las lámparas inferior a 15 cm, por lo que la dosis recibida se mantiene en el rango de máxima de irradiancia posible para la potencia que ofrecen las lámparas UV-C. In this way, the garments are kept at a distance of less than 15 cm from the lamps, so the dose received is kept within the maximum irradiance range possible for the power offered by UV-C lamps.
Utilizando lámparas apropiadas, la dosis letal para los microorganismos presentes en la prenda se alcanzará con una exposición inferior a 60 segundos. Using appropriate lamps, the lethal dose for the microorganisms present in the garment will be reached with an exposure of less than 60 seconds.
La invención además incorpora medios de seguridad destinados a impedir que la radiación UV-C pueda emitirse hacia el exterior de la máquina. The invention also incorporates security means intended to prevent UV-C radiation from being emitted towards the outside of the machine.
