Definitions

  • the invention relates to an expandable respirator against breathable airborne epi- and pandemic diseases, which can be worn by healthy and sick users and which protects both the wearer from infectious contamination and the environment from the possibly infectious wearer.
  • scenario 3 Sick user suffering from the pandemic disease: As in scenario 2, the breathing mask is bypassed during the sneezing process and an infectious cloud of secretion is also released.
  • the present invention enables carriers and passers-by to be protected against infection for all three of the above scenarios and at the same time opens up a simple and cost-effective way of interrupting chains of infection and thus stopping or preventing pandemics.
  • Usual respiratory half masks are worn over the mouth and nose. They consist of a flexible face part to which a replaceable filter cartridge is flanged.
  • the face piece consists of a flexible, soft rubber material that rests on the face by means of sealing lips along a closed sealing line. With straps that are pulled over the head, the mask is gently pressed against the face and thus lies tightly on it.
  • Conventional particle-filtering masks consist of a hemispherical filter fleece, which is also worn with straps over the mouth and nose and which is shaped in such a way that a sealing line is created.
  • the invention relates to an expandable breathing mask which consists of four functional components (see FIG. 1):
  • Components 2 the cough and sneeze modulator [2] and 3, the secretion and sputum absorber [9] and their arrangement together with the other two components to form an expandable breathing mask are particularly innovative.
  • the face part [1] of the mask according to the invention is worn as usual over the mouth and nose and is designed similar to that of a respiratory half mask described above, preferably with rubber-like sealing lips.
  • the face part is fixed over the head by means of a holding strap.
  • it In contrast to conventional respiratory half masks, however, it has a flange with a relatively large diameter, preferably directly in front of the mouth and nose.
  • An innovative core of the invention is the sneeze-and-cough modulator [2], which is arranged between the sealing face part and the (particle) filter.
  • the stationary side it is attached to the flange of the face piece; on the other, expandable side, a (particle) filter is attached.
  • the sneeze-and-cough modulator itself consists of an expandable hollow body, which can assume two target states with corresponding transitions: the resting state and the expanded state. In the resting state it comprises the rest volume, in the expanded state it comprises the expanded volume which, in relation to the resting volume, has a factor of at least 0.5 and preferably 2 and higher. During normal inhalation and exhalation, the sneeze-and-cough modulator is in a state of rest and allows the breath air to flow from the mouth and nose to the (particle) filter.
  • the breathing air passes into the environment and is filtered at the same time.
  • Virus-containing contaminants droplets, particles, secretions
  • corresponding virus-containing contaminants are retained in the exhaled air of an infected carrier, whereby the environment is protected from the infected carrier.
  • the usufruct modulator changes to the expanded state. This process is triggered by the sudden increase in pressure, which is disproportionate in comparison to inhalation and exhalation, due to the sniffing or flowing process.
  • the sneeze-and-fluff modulator thus removes a large part of the increased amount of breath air that suddenly escapes and thus prevents too high a flow rate at the (particle) filter or a brief detachment of the mask with side exit and entry of possibly contaminated air.
  • After the sneezing or coughing event it retreats back into its original state of rest, with the volume of air conveyed during the sneezing or coughing process escaping via the air filter with a delay.
  • the secretion and sputum absorber [9] is another innovative core of the invention. It is arranged in the interior of the sneeze-and-cough modulator and possibly the (particle) filter. It picks up the droplets, secretions, lumps of mucus or sputum conveyed during the sneezing and coughing process.
  • It consists of loose, breathable fleece or sponge material and is preferably also designed to be expandable - in the manner of a handkerchief, which unfolds briefly during the sneezing or coughing process, absorbs the secretions and then moves back with the sneeze-and-cough. Folds the modulator back together. This is achieved in that one side of the secretion-and-sputum absorber is connected to the stationary end of the sneeze-and-cough modulator and the other side is connected to the expanding end. The same applies to a possible mustache process. A secretion that is sometimes secreted by the nose with colds during normal breathing (runny nose) is also absorbed by the secretion and sputum absorber.
  • the secretion and sputum absorber can be equipped as a consumable part together with the (particle) filter, which is inserted and / or clicked into the sneeze and cough modulator. In this way, this combined consumption unit can be changed regularly when the intake capacity is exhausted. Furthermore, a pushed together film tube can be used up in a ring on the outside and connected to the consumption unit on one side, which is pulled over the consumption unit when it is removed, so that an infection-protected bag is in place, which can be closed and properly disposed of.
  • the invention thus provides reliable protection against infection even for sick carriers and at the same time prevents the creation of a viral load in the ambient air as a result of this. If the invention is consistently worn by all or a majority of passers-by, public and working life in the event of a wave of illness or a pandemic can go without a hitch disproportionate risks to life and limb are maintained. Chains of transmission can be effectively and easily interrupted and pandemics can be prevented or stopped (pandemic stopper). Preferred variants of the invention

Abstract

L'invention concerne un masque de protection respiratoire expansible pour utilisateurs sains et malades, qui, lors d'un processus d'éternuement ou de toux intempestif de la personne qui le porte, peut en un temps limité se dilater à l'aide d'un modulateur d'éternuement et de toux, et ainsi prendre en charge les sécrétions émises lors de l'éternuement ou de la toux au moyen d'un absorbeur de sécrétions et d'expectorations, sans que la fonction de filtrage des particules et gouttelettes chargées en virus ne se trouve interrompue. Les personnes saines porteuses du masque peuvent ainsi se protéger activement, alors que les personnes malades porteuses du masque évitent d'infecter leur environnement. Lorsque les personnes portent le masque, qu'elles soient malades ou non, les chaînes de contamination aéroportée peuvent être rompues de façon active et économique, et les pandémies correspondantes peuvent être circonscrites (stoppeur de pandémie).
