Description

The claimed invention relates to medical devices, in particular to devices that provide the user with the ability to provide safe and hygienic clean artificial ventilation of the lungs. The claimed device can be used by ambulance teams, traffic police units, firefighters, emergency services, as part of first-aid kits in institutions, as well as for retail.

State of the art

A solution is known ((Resuscitation mask »US 5161523 A comprising a protective cloth and a filter in the central part, while the protective cloth consists of two parts external rigid and adjacent to the filter transparent not rigid enough.

The disadvantage of this solution is that the protective fabric is made rigid preferably from celluloid and has an arcuate shape enveloping the face of the patient. Another drawback is the implementation of the canvas consisting of two different materials external hard and transparent adjacent to the filter. This leads to production complexity and requires different materials for production. Another disadvantage is that the face shape of patients is different and the shape of the hard part of the canvas can interfere with the implementation of artificial ventilation (breathing from mouth to mouth). Another disadvantage is that due to the hard fabric, it is inconvenient to transport it in anticipation of first aid. (US 5161523 A https://patents.google.com/patent/US20160243323A1/en?oq=US3626936A)

The closest analogue can be considered a device ((Barrier Device »US 20160243323 A1 including an upper element and a lower element connected to the middle element located between the upper and lower elements; the middle element contains a hole located in it; the upper element includes a hole located through it, and the hole of the upper element is smaller than the hole of the middle element; while the valve cuts into the lower element by cutting one or more lines through it; while the hole of the upper element is usually superimposed on the hole of the middle element when the upper element is located above the middle element while the valve and the hole of the upper element together form a one-way valve.

A disadvantage of the known solution is the complexity of the design, the increased density of the web obtained from the connection of three parts, which causes inconvenience when using, in particular, it does not envelope the shape of the face. Manufacturing costs. (US 20160243323 A1 https://patents.google.com/patent/US5161523A)

Disclosure of the invention.

The objectives of the claimed invention is the development of the design of the mask for artificial ventilation of the lungs, which provides protection to the user with the simplicity of the design, which would be convenient for storage and transportation and does not require a large set of materials and complex technological processes in production.

Within the framework of this decision, as a user, it is worth understanding a person who, due to emergency, provides medical assistance to the victim in the form of mechanical ventilation (breathing from mouth to mouth). Such users can be ordinary citizens who purchase this device as an element of first-aid kits, or an independent element of retail sale, as well as service employees whose duties include performing mechanical ventilation.

The tasks are achieved due to the design consisting of a solid protective fabric (1) with an air hole (1.1) with a closed filter (2) of FIG. 1-3.

The protective fabric (1) and the filter (2) are interconnected by a connecting layer (3) of FIG. 3.

An adhesive layer and / or a welded and / or solder joint can act as a connecting layer.

The connecting layer may extend along the entire contour of the hole (1.1) or along the contour of the filter (1.1) or fill the entire space between the edge of the hole (1.1) and the outer edge of the filter (2) of FIG. 3. May be continuous and / or located fragmentarily or pointwise.

The protective sheet (1) along the external contour can have a complex shape, for example, repeating the shape of a face, or in the form of any geometric shape, for example, a circle, oval, square, rectangle of FIG. 2, a triangle, a trapezoid, a hexagon, including having a shape based on the conjugation of simple geometric shapes. In this case, the canvas (1) should have a size at least covering the lower part of the patient’s face, with a preferred width to length ratio of 1 / 1.5. A preferred shape is the horizontally oriented rectangle of FIG. 1, 2 including with rounded corners

The canvas (1) in the central part has at least one through breathing hole (1.1) of FIG. 2, designed to circulate air during artificial respiration. It should be noted that the shape of the hole (1.1) may take the form of a geometric figure, the circle of FIG. 2, rectangle, oval.

The protective cloth is made of thin polyethylene and allows you to bend around the bends of the victim’s face and at the same time reliably protect both the user and the victim, as well as easily apply a mask to the victim’s mouth with a filter.

The protective cloth in the particular case of execution can be made transparent or translucent, and / or have printed images and / or text, for example, demonstrating and / or describing the process of artificial respiration and / or marking the correct position of the mask. All this is aimed at the correct masking and artificial ventilation of the lungs (breathing from mouth to mouth).

The filter (2) on the web is aligned with the breathing hole (1.1) and closes it completely beyond the edges of the hole in FIG. 2. This design allows you to make the product thin, in the process of using enveloping any face relief, without reducing the protective functions.

The filter (2) may be in the form of a geometric shape, the circle or rectangle of FIG. 2, or an oval or figures of complex shape, but it should close the hole (1) and go beyond its edges.

The filter (2) can be made of both fabric and non-woven, and / or may have one layer or several. Also in the particular case of execution can be performed with impregnation with disinfectants.

Due to the thin malleable fabric and the filter occupying an insignificant part, the mask can be conveniently stored until use, for example, folded several times along and / or across.

As a result, the claimed mask has a simple structure consisting of two elements that are securely mated with each other, it envelops the face of the victim, is convenient for storage and transportation, and protects both the user and the victim during mouth-to-mouth artificial respiration.

Brief Description of the Drawings:

FIG. 1 is a schematic illustration of a mask of a front view from above;

FIG. 2 is a schematic illustration of a mask top view;

FIG. 3 is a schematic representation of magnification (B) of FIG. 2 in section AA;

A brief description of the structural elements:

1 - a protective cloth;

1.1 - hole;

2 - filter;

3 - a connecting layer;

Principle of operation.

The claimed device does not require additional devices for use. Before starting, it is necessary to open the victim’s mouth and clean the oral cavity from secretions, if any. Further, the claimed device is placed in such a way that the filter (2) fits snugly on the lips of the victim, to spread the protective sheet (1). After this, you can proceed to provide emergency medical assistance to the victim by performing mouth-to-mouth artificial respiration.

In the case of eating before use, the mask was folded several times along and / or across for convenience of storage; the mask is unfolded before being placed on the victim’s face.

It should be noted that it is preferable to install the mask with a filter from the patient.
