Abstract
Disclosed is a screen for personal health protection, formed by one or more preferably transparent plates and one or more fans that cause air to circulate along the external surface thereof, such that possible microparticles expelled from the user's mouth are swept away, thereby preventing the air of two opposite areas from being exchanged through a service opening, preventing the spread of unwanted viruses and bacteria. The screen can be fixed or portable and can also be placed on the visors of conventional caps, also generating an air current along the external part of the visor that sweeps the microparticles towards the ground, without brushing the user's face. A second visor superposed such that the air circulates between them can be provided.
Description
MAMPARA DE PROTECCIÓN SANITARIA PERSONAL
PERSONAL HEALTH PROTECTION SCREEN
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere a una mampara de protec ción sanitaria personal para mostradores de atención al público o simila- res, fijos o portátiles, que presenta la característica de evitar la contami nación de persona a persona mediante la implantación de un sistema de ventilación interno que crea una corriente de aire circulante para estable cer una separación de ambientes y/o la separación por barrera de aire, de espacios abiertos y/o cerrados. The present invention refers to a personal health protection screen for customer service counters or the like, fixed or portable, which has the characteristic of avoiding contamination from person to person by means of the implantation of an internal ventilation system. that creates a circulating air current to establish a separation of environments and / or separation by air barrier, of open and / or closed spaces.
El objeto de la invención es conseguir evitar el contagio di recto y/o la contaminación del ambiente, por el spray o lanzamiento de micropartículas expedidas en el habla o bien el estornudo, que procedan del cliente que se encuentre al otro lado de la mampara que actúa de separación.
ANTECEDENTES DE LA INVENCIÓN The object of the invention is to avoid direct contagion and / or contamination of the environment, by the spray or launching of microparticles emitted in speech or sneezing, which come from the client who is on the other side of the screen that acts of separation. BACKGROUND OF THE INVENTION
Se conocen las mamparas simples de separación en los mostradores de atención al público, que casi siempre se crean para la protección de la seguridad de las personas que atienden al público, y que en muchos casos es para establecer una barrera de protección contra el robo o la agresión, y comúnmente estas mamparas son fabricadas de cristal blindado o plásticos transparentes que permiten la vista de las personas interlocutoras, disponiendo casi siempre de pequeñas aberturas o ventanillas para el intercambio de objetos entre ellas. También con la pretensión de que actúen a modo de barrera física para evitar el contagio, sin que se demuestre su efectividad, ya que, en la mayoría de los casos, la nube de micropartículas proyectada puede superar la barrera por todos sus lados, también por la parte superior, lo que pone en riesgo al depen- diente/es que atienden al público desde el mostrador; además de conside rar a las personas que estén presentes en otros espacios contiguos. Simple separation screens are known at customer service counters, which are almost always created to protect the safety of people who serve the public, and which in many cases is to establish a barrier to protect against theft or aggression, and commonly these screens are made of armored glass or transparent plastics that allow the view of the interlocutors, almost always having small openings or windows for the exchange of objects between them. Also with the claim that they act as a physical barrier to prevent contagion, without demonstrating their effectiveness, since, in most cases, the projected cloud of microparticles can overcome the barrier on all sides, also by the upper part, which puts at risk the clerk / s who serve the public from the counter; in addition to considering the people who are present in other contiguous spaces.
A veces se dispone de orificios a la altura de la boca para que puedan comunicarse, o bien de elementos electrónicos, como puede ser micrófonos y altavoces.
También son conocidas las mascaras faciales portátiles a modo de careta transparente que cubre el frente del rostro de las perso nas. Estos sistemas de separación tienen el inconveniente de que son incapaces de evitar que los posibles gérmenes que se expulsan por la boca a modo de micropartículas alcancen a las otras personas motivando el contagio de enfermedades, ya que el aire contaminado puede sobrepa sar la barrera, o bien, traspasar los orificios de la pantalla protectora o infectar las áreas de trabajo por reposo de las mismas una vez limitada su suspensión en el aire. Sometimes there are holes at the level of the mouth so that they can communicate, or electronic elements, such as microphones and speakers. Portable face masks are also known as a transparent mask that covers the front of people's faces. These separation systems have the disadvantage that they are unable to prevent possible germs that are expelled through the mouth as microparticles from reaching other people, causing the spread of diseases, since the contaminated air can exceed the barrier, or either, penetrating the holes in the protective screen or infecting the work areas by resting them once their suspension in the air has been limited.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
La mampara de protección sanitaria personal que se preco niza ha sido concebida para resolver la problemática anteriormente expuesta, ya que se basa en que la mampara dispone de un sistema de ventilación forzada que produce una corriente de aire de presión positiva que evita el intercambio de los dos ambientes a cada uno de los lados de esta. Actuando a modo de espacios de presión negativa para espacios de
aislamiento y, por ende, de anticontaminación. The personal health protection screen that is precocious has been conceived to solve the problems previously exposed, since it is based on the fact that the screen has a forced ventilation system that produces a positive pressure air current that prevents the exchange of the two main rooms on each side of it. Acting as negative pressure spaces for spaces of insulation and, therefore, anti-pollution.
La mampara pues, se configura de manera que dispone de uno o varios ventiladores, que provocan una corriente de aire que se desliza por su superficie, arrastrando hacia abajo, de manera lateral y superior, las micropartículas lanzadas desde la boca de la persona que se acerca al mostrador, haciendo que el spray o nube proyectada no pase al otro lado de la mampara de protección donde se encuentra el dependien te y/o la persona que quiera estar protegida. Ello se produce, bien porque el aire se conduce mediante deflectores, o bien mediante conducciones expresas o simplemente mediante corrientes de aire de dentro hacia fuera, creando una depresión o presión negativa entre ambos lados. The screen is therefore configured so that it has one or more fans, which cause a stream of air that slides across its surface, dragging the microparticles thrown from the mouth of the person downward, laterally and superiorly. approach the counter, ensuring that the spray or projected cloud does not pass to the other side of the protection screen where the clerk and / or the person who wants to be protected is located. This occurs, either because the air is guided by means of deflectors, or by express pipes or simply by air currents from the inside to the outside, creating a depression or negative pressure between both sides.
