RU199561U1 - FACIAL PROTECTIVE MASK - Google Patents

Abstract

The utility model refers to medical and other products that provide a barrier to direct transmission of infectious agents between people and between people and the environment, as well as to protect the human respiratory system from dust, smoke, fog and other harmful aerosols: Polish cotton, ranfors fabric, etc. etc. The technical problem solved with the proposed utility model consists in the unification of protective masks, which will allow, depending on the field of application and protection class, to apply one or another filter material and hooks, leaving unchanged the method of fixing the masks on the head. The technical problem is implemented as follows: in the proposed design of the mask, special removable reusable devices are used to secure the filter material and hooks. Each removable device includes one central and two symmetrical side petals. On the petals there are riveted buttons, by means of which the filter material and hooks are fixed on removable devices. In this case, both parts of the same rivet button are installed on the central petal, one part of the rivet button (for example, a pin) is fixed on one of the side petals, and the counterpart of the same rivet button is installed on the second side petal (cover with a lock ). The removable device itself is made of elastic material. For example, leather. The use of removable devices will allow unifying the design of protective masks, completing it, depending on the purpose and protection class, with various filter materials and hooks. In addition, it provides an opportunity for the wearer of the mask in emergency cases, when a standard mask is missing or its resource is exhausted, and there is nothing to replace it with, to independently select the material for the filter using available means. For example, gauze, handkerchief, or other woven or non-woven material. Of course, such a mask will not be completely equivalent to a factory one, but it will still provide some protection. For example, a mask made from fabric with your own hands can help with seasonal allergies. For those who are allergic to flowering plants, doctors recommend wearing such a mask when going outside. It can limit the entry of the allergen into the body during breathing.

Description

The utility model refers to medical and other products that provide a barrier to the direct transmission of infectious agents between people and between people and the environment, as well as to protect the human respiratory system from dust, smoke, fog, and other harmful aerosols.

Respirators are known from the prior art (GOST 12.4.294-2015) - personal respiratory protection equipment (RPE) from the ingress of hazardous aerosols (dust, smoke, fog, harmful gases, etc.), including for protection against bacteria and viruses. A respirator structurally, like a medical mask, consists mainly of a filter material and a device for attaching to a person's head.

There is also a known medical mask (GOST R 58396-2019), which by design features is close to the proposed utility model, so it can be taken as a prototype. A medical mask is a disposable medical device that covers the mouth and nose of the wearer and provides a barrier for the direct transmission of infectious particles from the wearer to other people, as well as for protecting the wearer's face from large splashes. The medical mask is not intended to protect the wearer from inhalation of bacterial and viral particles. A medical mask structurally consists of a filter material and hooks fixed on it from both sides. The term "hooks" in this case means ear loops, ties, elastic bands, etc., made of various materials, and designed to fix the mask on the head of a person. Usually the hooks are permanently attached to the filtering material (glued, sewn on, or fixed in another way). There are a lot of designs of protective masks, they use all kinds of filtering materials and they are attached to the head of a person in various ways.

The disadvantage of the above design is that the mask, after being used for its intended purpose, is disposed of as a whole, together with the ties, since they are permanently attached to the filter material. This method of attaching strings is not economically viable. In addition, due to the fact that there are many designs of protective masks, and they are not unified, their cost remains high.

Various woven and non-woven materials are used as the filtering material of the mask, depending on its purpose and protection class. For example, gauze, neoprene, polish cotton, ranfors fabric, etc.

The technical problem solved with the proposed utility model consists in the unification of protective masks, which will allow, depending on the field of application and protection class, to use one or another filter material and hooks, leaving unchanged the method of fixing the masks on the head.

The technical task is implemented as follows:

In the proposed design of the mask, special removable reusable devices are used to secure the filtering material and hooks. Each removable device includes one central and two symmetrical side petals. On the petals there are riveted buttons, by means of which the filter material and hooks are fixed on removable devices. At the same time, both parts of the same rivet button are installed on the central petal, one part of the rivet button (for example, a pin) is fixed on one of the side petals, and the counterpart of the same rivet button is installed on the second side petal (cover with a lock ). The removable device itself is made of elastic material. For example, leather.

The use of removable devices will make it possible to unify the design of protective masks, completing it, depending on the purpose and protection class, with various filter materials and hooks. In addition, it provides an opportunity for the wearer of the mask in emergency cases, when a standard mask is missing, or its resource has been exhausted, and there is nothing to replace it with, to independently select the material for the filter using available means. For example, gauze, handkerchief, or other woven or non-woven material. Of course, such a mask will not be completely equivalent to a factory one, but it will still provide some protection. For example, a mask made from fabric with your own hands can help with seasonal allergies. For those who are allergic to flowering plants, doctors recommend wearing such a mask when going outside. It can limit the entry of the allergen into the body during breathing.

For reference: Rivet buttons represent a metal platform in most cases of a round shape with two components: a protruding (bolt-shaped) pin and a cap with an internal retainer for the "bolt". The button is fixed by the spring force or the material of the button itself. The main advantage of the fastener is the ability to install on dense materials (tarpaulin, leather). Thanks to the automation of the fastening process, labor productivity and product quality are significantly increased.

One of the possible design solutions for a protective mask is shown in the drawings.

Figure 1 shows the design of a reusable removable device.

Figure 2 shows a method of attaching the filter material and hooks to the removable device.

The removable device, reusable, includes a central 1 and two side lobes 2 and 3, located symmetrically to the central lobe. On the central and side petals there are 4 pins and 5 fasteners. Side tabs 2 and 3 are designed to clamp the filter material 7 by bending them and snapping parts 4 and 5 of the button-fastener. Two parts 4 and 5 of the second button-clasp installed on the central petal 1 are intended for clamping the hook 8.

The face shield is assembled and used as follows:

Both ends of the filter material are folded like an accordion, laid along the central petal and fixed in this position with clasp buttons mounted on the side petals by folding them. Hooks (eg rubber rings) also fit between the two snap-fastener parts mounted on the center petal and are fixed in the same way as the filter material. After that, the assembled mask is installed on the face, and the hooks (for example, ear hooks) are wound behind the auricles. In this case, the mask should cover the nose, cover the chin and cheeks.

Claims (1)

A face protective mask containing a filtering material and hooks for fixing the mask on a person's head, characterized in that removable reusable devices are used to fix the filtering material and hooks, equipped with snap fasteners installed on the central and symmetrical side petals of the removable device, and removable the device is made of elastic material.
