Definitions

  • the present invention is comprised within respiratory protection mask devices.
  • the masks usually protect the mouth, nose and mucosa of the user from splashes of body fluids, blood or other, but to be effective they must be self-filtering and must be discarded in most cases once used.
  • allergic elements such as pollen particles or mites can be found in the air
  • different types of microorganisms, germs or bacteria can be found in the air
  • polluting elements such as fumes, liquids or gases, which can penetrate most masks through gaps, wrinkles or lack of sealing or adjustment of these, since they are not ergonomic and watertight to the face of the wearer, as well as the inability of the material to filter the elements or microorganisms pathogens.
  • Typical masks are made with fabrics or fabrics, which cannot be hermetically adapted to the wearer's face, because the fabrics used are not elastic or ergonomic, therefore it is impossible to achieve total contact with the skin of the wearer's face. and it cannot be avoided that there are open areas with gaps or wrinkles, between the face of the user of the mask and the mask itself, consequently, the nose or mouth of the wearer are exposed to microorganisms and these masks cannot offer total protection of the respiratory tract, that is, of the mouth and nose of the user.
  • Another problem with typical masks is that they fit either too loose, not protecting properly or too tight, causing discomfort.
  • Some masks can be so loose and woven so flimsy that they move during head movements or common facial movements associated with speech, even moving with the wearer's breath and exhalation. This requires the user to be forced to perform the action of readjustment and repositioning of the mask, which is extremely dangerous to touch and have to readjust the mask with possibly dirty or contaminated hands.
  • contact of a mask with a gloved hand during a medical procedure is a violation of sanitary protocol, as the mask is not considered sterile and may contaminate the sterile glove or soiling or contamination of the mask itself by the gloves may occur. .
  • the movement of the mask can be so significant that it partially blocks the ocular region, which can lead to a decrease in the field of vision and the exposure of the wearer's nose and / or mouth to pathogenic microorganisms.
  • respiratory protection masks are not in any case enough to avoid contagion, since viruses can penetrate through the eye area, that is why eye protection, glasses, face shields or domes must be used additionally, which act as a barrier and protect the user by means of a physical barrier, especially in the cases of medical professionals who must be within walking distance of infected persons.
  • These protective barriers act by avoiding direct contact, for example, secretion or saliva caused by a cough or sneeze of a patient, directly on the mask or glasses of the health worker or people in general, which makes a user at risk of contagion , you must use at least two or more pieces, for respiratory and eye protection.
  • each individual protection element PPE
  • PPE protection element
  • these protections can be worn for long working hours, not being comfortable and disturbing in each of the areas where they are held.
  • PPE independent protective pieces
  • each one must be placed in a position and done alternately, that is, first the mask and adjusting it, secondly the glasses, having to adjust correctly and thirdly the face shield. and also adjust it correctly, to avoid that all of them move from the correct position or move independently of each other.
  • Typical masks include a body that covers the wearer's nose and mouth and one or two fixed tapes or straps, which are attached to the body and which the wearer must tie or adjust behind their head, or on their ears, to secure the fit. mask to your face.
  • the fact of having two sets of fixed straps that are more or less elastic does not provide the masks with adaptability, since the wearer can place the straps according to their comfort and preference, and they may not be sufficiently elastic or they may not be in the right place. and this can generate, unwanted displacements of the mask, or as we have explained previously, there are gaps or wrinkles in the adjustment with the face of the person.
  • the adjustment systems of the protective glasses are usually supported on the upper part of the ears, by means of "temples", in this case, the glasses cannot have a correct seal to the user's skin, therefore, the protection against Infection is only frontal, but it does not protect against the possible entry of viruses through the lateral areas and around the eyes.
  • hermetic protective goggles In the case of hermetic protective goggles, they usually have an elastic strap as an adjustment that is placed behind the user's head, and said elastic strap must be placed above or below the mask fastening rubbers, which makes To remove or reposition one of the pieces, the other must be removed, producing an extra manipulation, something not recommended compared to prevention, since prevention protocols advise that the least possible manipulation should be carried out with the hands and in the if necessary, hands should be thoroughly washed prior to handling the PPE elements.
  • the adjustment systems of the face protection screens are usually plastic pieces or elastic bands that are placed around the user's head and are adjusted at the back. These positioning systems are usually uncomfortable, since if they are tightened a lot, the pressure that is exerted around the head and on the forehead is very annoying, in addition the sweat that occurs on the user's forehead, causes it to cause discomfort, chafing and itching in the area, in addition to complicating the sweat-drying action during medical, surgical and / or professional work, if, on the contrary, the circular adjustment of the screen on the head is not tightened correctly, the screen may fall of the head by tilting the user or it can turn on itself by movements, ceasing to protect the front part of the face.
  • a user who must be properly protected against contagions, for example as in the case of health workers or other professionals, must wear at least three pieces of protection, a mask, glasses and a protective face shield, with their fixing elements. each of them tied or adjusted behind their head and around it, or even in their ears, each of these protective pieces are independent and must be placed in an orderly and independently, likewise and in the same order must be removed. Being very cumbersome and uncomfortable to carry so many independent elements on the head for a long period of time and especially being very difficult, complicated and uncomfortable to prevent at least one of them from moving or moving, without having to move or remove another, to return to reset the one that had moved and vice versa. In short, a user with three pieces of protection on the head, must be continually aware of and concerned about the correct placement of each of them.
  • the material with which protective masks are usually made do not allow washing, they are usually made of fabrics, fabrics or fibers that are not suitable for contact with water, soaps, detergents or disinfectants. In addition, they are not normally resistant to high disinfection temperatures, causing deterioration in the case of washing, rendering them useless.
  • a common disadvantage of typical masks is that a wearer's goggles can fog up when vapor from the wearer's exhaled breath escapes through the fabric or material from which it is made, or condensation or vapor escapes from the top. of the mask and go up to the glasses or screen, because the masks are not fully adjustable to the skin, and they are not hermetically sealed in the contact area. This problem is exacerbated when there is a large gap between the top of the mask and the wearer's face or when the wearer's breath passes through the top of the mask or through its tissue.
  • wearers To prevent fogging and reduce heat build-up in a typical mask, wearers often do not secure the tie assembly tightly and allow steam to escape through the bottom of the mask, which is a serious problem of safety, they also have to carry out cleaning tasks of the glasses often, to be able to see correctly through them, with the serious danger of handling the glasses with hands or gloves that may be contaminated.
  • the masks are divided into two groups, those for protection and those for medical treatments.
  • Those of protection are usually depending on the quality of filtering of one type or another and level of security and try to prevent an infected person from expelling microorganisms into the air together with remains of saliva or air that they exhale, as well as those with greater protection , try to prevent an individual from inhaling microorganisms through respiration.
