Abstract

Respiratory protection mask, in particular a medical disposable mouth and nose protection mask (12), comprising an at least single-layer filter layer (14) made of polypropylene SMS or SSMMS nonwoven, lateral elastic drawstrings (20) made of a latex-free material and a nasal clip (14) a wire that is flattened at least on the side facing the user.

Description

The innovation relates to a respiratory protection mask, in particular a medical disposable mouth and nose protection mask.

From the DE 20 2020 101 979 U1 a respiratory protection mask designed as a half mask is known, in which at least one outer layer and at least one inner layer are provided, the outer layer and the inner layer each having at least one breathable textile fabric and / or consisting of such a fabric and wherein between the outer layer and the inner layer at least a mask pocket is formed for the exchangeable reception of at least one disposable filter layer. The half mask also has lateral drawstrings.

The task of the innovation is to propose a simpler production of the mask with increased wearing comfort and comparable filter effectiveness.

The object is achieved by the features of claim 1.

The respiratory protection mask according to the invention, in particular a medical disposable mouth and nose protection mask, comprises a preferably single-layer filter layer made of polypropylene SMS or SSMMS non-woven fabric, lateral elastic drawstrings made of latex-free material and a nosepiece made of a wire that is flattened at least on the side facing the user, with the material of the filter layer has a weight per unit area of 35-60 g / m ² . With a weight per unit area of 43 g / m ^{2, the} pressure difference of this filter material is 24 Pa / cm ² , so that easy breathing is made possible. At the same time, it is sufficient with regard to the liquid resistance of DIN EN 14683 and the germ tightness in moisture of DIN 58 953-6.

The drawstrings of the mask consist of a composite of PP spunbond and a Lycra thread. They are free of latex, but elastic and gentle on the skin.

The nasal clip consists of a flattened wire on the side facing the wearer of the mask, in particular an oval aluminum wire. The material is only light in weight, is easily deformable and therefore easily adaptable to the contour of the face, and the flattening distributes the pressure over a larger area of skin.

Further features and advantages of the invention emerge from the following description which, in conjunction with the attached drawing, explains the invention using an exemplary embodiment.

The only figure in the drawing shows the head 10 a mask wearer with a mask 12 . The latter consists of a single layer of filter 14th made of polypropylene SMS or SSMMS nonwoven. It is made in a known manner from a substantially rectangular piece of material and in several folds 16 placed that on the margins 18th the mask 12 with the rest of the material 14th are connected.

On the margins 18th are also the drawstrings 20th (only a drawstring can be seen) attached. They are loop-shaped and used to attach the mask 12 on the ears 22nd certainly. In the nasal area a nasal clip extends from one side to the other 24 made of a flattened (not shown) wire on the side facing the wearer of the mask, in particular oval aluminum wire.
