SK9376Y1 - Respiratory protective aid - Google Patents

Abstract

The respirator with clamping elements and a nose clip consists of a body (1) formed by a filter material and at least one one-way inspiratory valve (2) for the release of inhaled air, located in the body (1) of the respirator.

Description

SK 9376 Υ1

Field of technology

The technical solution relates to a respiratory protective device, in particular a face mask or half mask, which serves to prevent the spread of bacteria, vines and other pathogens.

Prior art

A number of respiratory protective devices are currently known, whether respirators, drapes, or face masks. Their common feature is that they should primarily protect their users from the negative effects of the environment, such as dust, pollen and other contaminants dispersed in the air, as well as harmful pathogens, bacteria and viruses.

Valve-free respirators filter both air supply and exhaust. They provide good two-way protection. Their disadvantage is the high breathing resistance, which is reflected in low comfort when using them. This is particularly difficult for the elderly and those with respiratory problems, especially during increased physical exertion and during the summer heat.

Respirators with one or more exhalation valves use one-way exhalation valves to reduce their mean respiratory resistance, remove heat and moisture from respirators. The result is an increase in user comfort. However, such respirators and protective masks provide protection only to their user. They cannot be used to protect a healthy environment from potentially infected users, which is their major disadvantage, especially during a pandemic, when we use them in most countries.

The essence of the technical solution

The respirator comprises a body 1, at least one one-way inspiratory valve 2 located in the body 1, preferably to the right or left of the central part of the body 1. The respirator is equipped with clamping elements 3 to secure the body 1 to the user's face and a nose clip 4 adapting the shape of the body 1 so that it adheres to the user's face as best as possible.

The body 1 is made of a filter material enabling the filtration of the exhaled air by the user of the breathing apparatus in the closed position of the one-way valve. The one-way breathing valve located in the body 1 of the breathing apparatus is open towards the user and closed away from the user, which allows the user to inhale unfiltered ambient air without resistance. In the closed position of the one-way breathing valve 2, the air exhaled by the user passes through the filter material of the body 1 and the filtered air enters the surroundings. The filter material of the body 1 is made of a filter material with a suitable filtering ability depending on the required properties for the purpose of capturing, whether viral, bacterial, dust or other particles harmful to the organism. For example, the filter material used can be a variety of woven and nonwoven materials, such as polypropylene, polyester, polyamide, polyacrylic, graphene, chiffon, silk, cotton, and the like, as well as any combination thereof.

The one-way inspiratory valve is of any design, provided that it is in the closed position when exhaled and in the open position when inhaled.

Such a respiratory protective arrangement has the advantage in particular of facilitating breathing and reducing moderate pressure breathing while maintaining the protection of a healthy environment from a potentially infected user.

Overview of figures in the drawings

In FIG. 1 is a schematic illustration of a single breathing valve breathing apparatus, showing the breathing phase when air flows through the one-way breathing valve toward the user.

In FIG. 2 shows a protective device with one inspiratory valve, showing the exhalation phase when the exhaled air flows through the filter material away from the user.

In FIG. 3 shows a protective device with two inspiratory valves.

Examples of embodiments

Example 1

The protective breathing apparatus consists of four parts, namely a body 1 formed by a filter material of polypropylene nonwoven fabric, which is cut and formed into the desired shape, an inspiratory valve 2 located to the right of the central part. In the part of the body 1 intended to accommodate the inspiratory valve, an opening is formed for fitting the inspiratory valve 2 into the filter material. Holes are also formed in the body 1 of the breathing apparatus for accommodating the clamping elements 3, which have sufficient force to ensure the required tightness of the body 1 on the user's face. Silicone microporous rubber bands are preferably used as clamping elements.

In the area of the nose, the body 1 has a nose clip 4 fitted, which helps to adapt the shape of the body 1 so that the body 1 adheres to the user's face as best as possible. The clamp is made of a pair of plastic-coated metal wires.

Example 2

The protective breathing apparatus consists of four parts, namely a body 1 formed by a multilayer filter material of cotton and polyester nonwoven fabric, which is cut and formed into the desired shape, the inspiratory valves 2 located to the right and to the left of the central part.

An opening for fitting the inspiratory valve 2 in the filter material is formed in the part of the body 1 intended to accommodate the inspiratory valve. Holes are also formed in the body 1 of the breathing apparatus for accommodating the clamping elements 3, which have sufficient force to ensure the required tightness of the body 1 on the user's face. Silicone microporous rubber bands are preferably used as clamping elements. In the area of the nose, the body 1 has a nose clip 4 fitted, which helps to adapt the shape of the body 1 so that the body 1 adheres to the user's face as best as possible. The clamp is made of a pair of plastic-coated metal wires.

Industrial applicability

The respirator is useful when there is a need to protect the public from a potentially infected wearer, especially during a pandemic.
