MULTI-PURPOSE REUSABLE PROTECTIVE MASK

USE

Description

The invention relates to medicine, namely to the protection of the respiratory organs and mucous membranes of the eyes from mechanical and other particles, including pathogenic and viral infections.

An analogue of the invention is a known medical (surgical) mask - a disposable medical product that covers the mouth and nose of the wearer and provides a barrier for direct transmission of infectious particles from the wearer of the mask to other people. The mask also protects the wearer's face from large drops.

The specified mask consists of a filter layer (gauze or non-woven bandage) with rubber loops for attaching to the ears.

Use the mask for two to three hours (according to information from the source - the free encyclopedia Wikipedia)

The disadvantages of this mask are as follows:

1. Complicates the wearer's breathing

2. Moisturizes from breathing, creates a favorable focus for the development of infection;

3. Does not protect against small viral infections;

4. Has a very short term of use;

5. Pollutes the environment after use;

6. Cannot be used by carriers with breathing problems; 7. When used by women, it damages makeup, which leads to inconvenience;

8. Difficult to put on and take off;

9. It spoils the aesthetic appearance of the wearer

10. Due to contact with the face and nose, it is not possible to apply an antiseptic.

The invention is based on the goal:

1. Make the mask a reusable item;

2. Do not obstruct the wearer's breathing

3. Reduce environmental pollution;

4. Simplify putting on and taking off with one hand;

5. Do not spoil the aesthetic appearance of the carrier

6. Do not damage makeup when used by women.

The technical result of the invention is that when using a multi-purpose protective mask of repeated use, the air that the wearer inhales and exhales does not come into direct contact with the air of the interlocutor, but is withdrawn after exhalation, and is removed for inhalation from behind the wearer's face (from the shadow zone).

In addition, if the carrier is a source of infection, filtering elements with an applied antiseptic installed in the front protective part will neutralize the infection.

In addition, in the manufacture of a face shield, together with goggles, the mucous membrane of the eyes will be protected from dust and infections. The technical result is achieved due to the fact that the protective plate is made of impenetrable transparent plastic and has the main purpose of diverting exhalation air and supplying inhalation air from behind the face, excluding direct contact of air masses.

An essential feature is that a reusable multi-purpose protective mask made of impermeable transparent plastic makes it possible to fold the mask and use it whenever necessary, with minimal functional costs after storage.

The invention is illustrated by drawings, where figure 1 shows a reusable multi-purpose protective mask where 1 is the front protective plate connected to the ear loops - 2, through the hinge - 3. On the inside of the face mask, special brackets are made - 4 for attaching the filter element.

Figure 2 shows a reusable multipurpose face shield (side view).

Fig. 3 shows a reusable multipurpose face shield, where the face shield is made of goggles 6.

Figure 4 shows a multi-purpose reusable face shield where the face shield is made of goggles 6 (side view).

Figure 5 shows a reusable multipurpose protective mask with a filter element 5 installed (side view).

6 shows a reusable multipurpose face shield where the face shield is made of goggles 6 with a filter element 5 installed (side view). Usage example.

The wearer puts on a reusable multipurpose protective mask by attaching the ear loops 2 to the ears.

During breathing, exhalation and inhalation air is guided by a face shield at the back of the head, eliminating direct contact of air masses with the interlocutor.

In the case of installing the filter element 5 (Figs. 5 and 6), inhaling and exhaling air contacts the filter element, as a result of which the heavier parts of moisture settle and condense on the porous surface of the filter element, where it is neutralized with an antiseptic.

After a short period of use, the mask is removed from the face, the filter element is removed from the mask, rinsed with water, the filter element is replaced.

It is also possible to apply logos, marks and various patterns on the transparent molded plastic of the mask.
