MASCARILLA BIOSANITARIA ANTIÚLCERALANTIULCERAL BIOSANITARY MASK
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a una mascarilla facial biosanitaria antiúlceral a base de silicona biosanitaria antiúlceral para dispositivos de inhalación que puedan ocasionar lesiones por presión y fricción. Esta mascarilla ha sido concebida y realizada para obtener numerosas y notables ventajas respecto a otros medios existentes de análogas finalidades.The present invention relates to an anti-ulcer biosanitary face mask based on anti-ulcer biosanitary silicone for inhalation devices that can cause pressure and friction injuries. This mask has been conceived and made to obtain numerous and notable advantages over other existing means of similar purposes.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Se conocen varias mascarillas biosanitarias antiúlceras para dispositivos de inhalación. En tal sentido pueden citarse mascarillas basadas en silicona de alta densidad esterilizada para uso sanitario, la cual presenta propiedades elásticas y una baja reactividad en los tejidos, lo que supone una leve deformación bajo la presión. Sin embargo, estos materiales presentan diversos inconvenientes, tales como la presión que ejercen sobre el usuario, la cual es proporcional a la ejercida sobre el mismo, lo que a largo plazo lo hace inviable, ya que una presión continua sobre el usuario acabaría produciendo una úlcera. En este punto pueden citarse problemas para el desarrollo de una interfase entre los materiales y el organismo, dada la mínima deformación del material que sufre bajo presión y la agresión que sufren los tejidos de los organismos al recibir esta presión constante. Various anti-ulcer biosanitary masks for inhalation devices are known. In this sense, masks based on sterilized high-density silicone for sanitary use can be mentioned, which has elastic properties and low tissue reactivity, which implies a slight deformation under pressure. However, these materials have various drawbacks, such as the pressure they exert on the user, which is proportional to the pressure exerted on it, which makes it unfeasible in the long term, since continuous pressure on the user would end up producing a sore. At this point, problems can be cited for the development of an interface between the materials and the organism, given the minimal deformation of the material that suffers under pressure and the aggression suffered by the tissues of the organisms when receiving this constant pressure.
Igualmente se conocen otros sistemas basados en mascarillas inflables, a los cuales se inyecta un fluido a presión durante el tiempo que se requiere aumentar la presión del material, desplazando el material hacía el usuario. Éstos reducen la presión de forma que solo aparece cuando se requiere para compensar alguna otra fuerza. Si bien nunca llega a desaparecer del todo la presión del tejido, ésta se cambia por fricción. Sin embargo el aumento de los costes y de complejidad, unido al peligro de fugas de las paredes elásticas del material por las continuas deformaciones, no compensa la mejora de aumentar el margen de tolerancia, ya que el problema de fondo sobre la aparición de úlceras, que condiciona su viabilidad económica, no se resuelve.Other systems based on inflatable masks are also known, to which a pressurized fluid is injected during the time it is required to increase the pressure of the material, moving the material towards the user. These reduce the pressure so that it only appears when it is required to compensate for some other force. Although the pressure of the tissue never completely disappears, it is changed by friction. However, the increase in costs and complexity, together with the danger of leaks from the elastic walls of the material due to continuous deformations, does not compensate for the improvement of increasing the margin of tolerance, since the underlying problem of the appearance of ulcers, that determines its economic viability, is not resolved.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
La mascarilla biosanitaria antiúlceral comprende cinco piezas: el recubrimiento elástico, el fluido no newtoniano, el polímero, el precinto y la estructura rígida, acoplables entre sí, formando un único objeto que es capaz de adoptar la forma del usuario, y mantener esta posición sin ocasionar molestias mientras recibe ventilación.The anti-ulcer biosanitary mask comprises five parts: the elastic coating, the non-Newtonian fluid, the polymer, the seal and the rigid structure, which can be coupled together, forming a single object that is capable of adopting the shape of the user and maintaining this position without cause discomfort while receiving ventilation.
Dicha prótesis presenta una nueva estrategia a la hora de adaptar la prótesis, aprovechando las múltiples propiedades presentes en los fluidos no newtonianos y los cambios producidos en los polímeros. A partir de unas propiedades adecuadas para la adaptación de la mascarilla al rostro, obtenemos unas propiedades adecuadas para la función de la mascarilla.Said prosthesis presents a new strategy when it comes to adapting the prosthesis, taking advantage of the multiple properties present in non-Newtonian fluids and the changes produced in the polymers. Starting from suitable properties for the adaptation of the mask to the face, we obtain suitable properties for the function of the mask.
Según los diferentes polímeros existentes, se eligen los que polimerizan en contacto con la atmósfera y se añaden partículas que mejoren la interfase con los tejidos y que faciliten su amasado, como las microesferas poliméricas expandibles en polvo de 40 micras de diámetro. Además, se ha previsto que el polímero permanezca aislado hasta haber adoptado la forma adecuada, momento en el que se debe retirar el precinto permitiéndole entrar en contacto con el aire, y por consiguiente iniciando la polimerización, completándose el sistema con un recubrimiento elástico que estará en contacto con la piel.Depending on the different existing polymers, those that polymerize in contact with the atmosphere are chosen and particles are added that improve the interface with the tissues and that facilitate their kneading, such as the 40-micron diameter expandable polymer microspheres in powder form. In addition, it has been planned that the polymer remains isolated until it has taken the appropriate shape, at which time the seal must be removed, allowing it to come into contact with the air, and therefore starting the polymerization, completing the system with an elastic coating that will be in contact with the skin.
Por todo ello las propiedades físicas finales de la mascarilla biosanitaria antiúlceral son las de un sólido suspendido en un fluido no newtoniano y recubierto por un elástico, mientras que las propiedades físicas iniciales serán las de un fluido casi perfecto dentro de un elástico.For all these reasons, the final physical properties of the anti-ulcer biosanitary mask are those of a solid suspended in a non-Newtonian fluid and covered by an elastic, while the initial physical properties will be those of an almost perfect fluid inside an elastic.
Además, se ha previsto que la mascarilla biosanitaria antiúlceral cuente con dos regiones de composición reforzada sobre el hueso nasal y bajo el cartílago del septo.In addition, it has been planned that the anti-ulcer biosanitary mask has two regions of reinforced composition on the nasal bone and under the cartilage of the septum.
