Abstract
A mouth-nose mask for reducing the transmission of pathogens via droplets of secretion is disclosed. The mouth-nose mask includes a central fold which defines a chin-nose line of the mouth-nose mask and separates the mouth-nose mask into two substantially congruent halves. A fastening means for fastening the mouth-nose mask to a wearer's ears or back of the head is attached to the ends of the two halves remote from the central fold. The mouth-nose mask includes at least two superposed layers of a filter material, the at least two layers defining the outer shape of the mouth-nose mask and being only partially joined to one another at their edges.
Claims46
A mouth-nose protection for reducing the transmission of pathogens by secretion droplets, the mouth nose protection comprising:
- a central folds defining a chin-nose line of the mouth-nose protection and configured to divide the mouth-nose protection into two substantially congruent halves;
- hand
- fastening means configured to fasten the mouth-nose protection to ears of a wearer or to a back of a head of the wearer, the fastening means further configured to attach to the ends of the two substantially congruent halves facing away from the central fold;
- and
- at least two superimposed layers of a filter material defining an outer shape of the mouth-nose protection and arranged only partially connected at their edges.

A method of producing a mouth-nose protection, the method comprising the steps of:
- providing a one-piece first layer of a filter material having an axisymmetric shape and a substantially congruent one-piece second layer of a filter material;
- arranging the one-piece first layer and one-piece second layer one above the other;
- folding of the one-piece first layer and one-piece second layer along an axis of symmetry so as to create a central fold;
- partial joining the one-piece first layer and one-piece second layer at their edges;
- and
- attaching one means of securing the mouth-nose protection to the ears or to the back of the head of a wearer at each end of the two halves facing away from the central fold.
