Description

DESCRIPTION

EPIRNIUS ACCESSORIES ANISOTROPIC MULTI-USE ADJUSTMENT FOR ADJUSTING AND HOLDING HALF-FACE PROTECTIVE MASKS TO THE USER'S FACE.

The present invention relates to a multi-purpose Epirinion Attached Anisotropic Insert used to fit and retain half-face protective masks on the wearer's face.

Such masks are surgical protective masks which are medical technological products manufactured on a case-by-case basis, according to National, European and International standards.

Such are also cloth protective masks which are not medical devices, but are widely used in place of surgical protective masks.

The degree of protection provided by the use of half-face protection masks depends on the materials with which they are made, on the design of their construction, but mainly depends on the degree of adaptation and retention on the user's face, which is also the parameter that determines the percentage of air inhaled and exhaled by the user that will be filtered.

The design proposal and choice of incorporating a soft and flexible metal sheet into the well-known half-face protective masks is a well-known solution to the problem of adapting these masks to the "abnormal" area of the nose.

From the study of the design and the experience from the use of the known half-face protective masks, it is found that the protection provided by this solution is insufficient.

The adaptation of an integrated soft and flexible lamina only temporarily minimizes the contact gaps between the face and the mask in the "abnormal" area of the nose. And this is because, the solution contains an obvious design contradiction. The lamina must be flexible and soft so that it can to be molded over the nose, but at the same time it must be hard and rigid so as not to deform, from the combined forces developed on it by the way the mask is held and the movements of the lower jaw when the wearer begins to speak.

Experience has shown that when the user begins to speak, the configuration of the soft integrated piriform metal plate does not "stand" the forces exerted on it, resulting in its gradual deformation and the appearance of contact gaps between the face and the mask, resulting in a large percentage of the air inhaled and exhaled by the user, to leak without being filtered.In fact, most of this leakage is directed towards the user's eyes, blurring, in low temperature conditions, the lenses of the glasses he is likely to use. Deformation is often followed by sliding the mask down and exposing the nose, thereby not only increasing the percentage of the user's inhaled and exhaled air that leaks unfiltered, but also forcing the user to repeatedly corrective movements in order to replace the mask, an action that can contaminate his hands and favor the spread of infectious and pathogenic agents.

Solutions are also known which propose rigid external additions to the masks to deal with the aforementioned problems.

The outer of these cheek extensions have the disadvantage of being fitted to the wearer's face by the mask rather than fitting the mask to the face. Thus a part of the addition is in contact with the face, excluding the contact of the mask with the face. Also, due to their isotropic construction, they cannot follow the changes that appear in the face during speech and from all kinds of grimaces of the user.

The external of these additions that work like common pegs in order to ensure stable retention and contact of the mask in the "abnormal" area of the nose exert constant pressure on it, which strains the nose and in some cases even causes shortness of breath.

Also none of said additions provide the possibility of configuring its central part based on the exact curvature of the nose of the user who will use the mask in which it will be used.

The purpose of the present invention is to minimize or even eliminate the above mentioned problems.

The minimization and even elimination of the above-mentioned problems is achieved, according to the present invention, by placing inside the half-face protection masks, in the abnormal area of the nose, a multi-purpose Attached Anisotropic Attachment Epirinion.

The present invention can be fully understood from the following detailed description and two examples of application, with reference to the accompanying drawings.

Figure 1 shows a multi-purpose Epirinium Accessory Anisotropic Add-on (10) according to the present invention, characterized in that: It can be made of one or more suitable materials, in such a form and in such a manner that the characteristics and properties that obtains along its longitudinal axis to differ between its central part and its two ends. Its central part presents such rigidity (11) that when it is shaped (12), in a suitable way, based on the curvature of the nose of the user who will use the mask on which it will be placed, the combined forces developed on it due to the way retention of the mask and the movements of the lower jaw when the wearer begins to speak, they cannot deform it. The combination of its shape and rigidity, obliges the mask to firmly embrace the "abnormal" area of the user's nose, to be firmly constituted by it, covering the nose and mouth and to remain adjusted without gaps in contact with the face. Its two ends (13) exhibit a scaled spring behavior (14) such that they copy the relief of the user's face and by firmly pressing the mask against it, they complete the adaptation of gapless contact to the "abnormal" area of the nose and cheeks.

It is also characterized by the fact that: It provides the user with the possibility to choose it, as the case may be, with its central part shaped or unshaped and to shape it in an appropriate way based on the curvature of his nose. It is placed on masks that have a suitable slot with an entrance for its placement. It also provides the user with the ability to multi-use by himself.

Figure 2 shows a half-face protective mask (21) according to the present invention, characterized in that it has a suitable Receptacle (22) with an Inlet (23) for the placement of the Attached Multi-Purpose Anisotropic Attachment.

The attachment of the Multi-Purpose Anisotropic Add-On Epirin on half-face masks, due to the rigidity and the way of shaping of its central part, and the graduated spring behavior of its two ends, which ensure a stable contact without gaps in the "abnormal" area of the nose and the cheeks, and the firm retention by the nose, which prevents it from sliding down and exposing the nose, gives them a number of advantages over known half-face protective masks.

Specifically: The percentage of unfiltered air inhaled and exhaled by the user is minimized. Eliminates the problem of blurring of the lenses in case the user uses glasses. The user is released from the obligation to carry out corrective movements with his hands to return the mask to the position that covers the nose and mouth. It also provides the user with the ability to multi-use by himself.

Example I

Figure 3 shows, in accordance with the present invention, an Epirinio Complementary Multipurpose Anisotropic Adduct (31), which is characterized in that:

Its central part is a Component (32) shaped on the basis of the curvature of the nose of the user who will use the mask in which it will be placed and is made of a suitable metal plate in a form and manner so that the combined forces developed on it due to the manner retention of the mask and the movements of the lower jaw when the wearer begins to speak, they cannot deform it.

Its two identical end parts are Attachments (33) integrated at the two ends of the central attachment and made of a suitable polymeric material in such a form and manner as to exhibit a stepped spring behavior (14) such as to copy the relief of the user's face and pressing firmly the mask on it, they complete the adjustment of the gapless contact in the "abnormal" area of the nose and cheeks.

Example II

Figure 4 shows, in accordance with the present invention, a Surgical Mask of type EN 14683/11 (41), with a Multi-Purpose Anisotropic Attachment (31) attached to it, and adapted to the user's face, which is characterized in that :

It has a suitable socket (22) into which the Epirinios Accessory Multi-Purpose Add-On (31) is fitted, from inlet (23).

With the help of the included Multi-Purpose Anisotropic Attachment Epirinium (31), it firmly hugs the wearer's nose, forms and firmly covers the nose and mouth, and remains firmly fitted without gaps in contact with the face in the "abnormal" area of the nose (42); and on the cheeks(43).
