Abstract
The invention relates to a respirator mask with hygienic protection. More specifically, the invention relates to a respirator face mask (2) which provides physiological protection, comprising: an oronasal face piece (10), a semi-flexible lip element (6) which is used to position the oronasal face piece (10) on the user's face (1), and hygienic protection means (4) which are removably-positioned at least partially inside the mask (2). The aforementioned removable protection means (4) comprise (i) a first part (4a) which provides hygienic protection and (ii) a second part (4b) which maintains the hygienic protection means (4) inside the mask (2), said second part (4b) co-operating elastically with the above-mentioned semi-flexible lip element (6) or the face piece (10).
Claims31
A respirator face mask providing physiological protection, comprising:
- an oronasal face piece which is connectable to a respiratory gas source, said oronasal face piece having a semi-flexible lip with an edge designed to position said oronasal face piece on a user's face and,
- a hygienic protection system removably positioned at least partly inside said oronasal face piece and including a first part which provides hygienic protection and a second part which secures said hygienic protection system to the oronasal face piece,
- wherein the edge of the semi-flexible lip returns toward the center of the oronasal face piece, defining an internal groove in the oronasal face piece, and said second part of the hygienic protection system is disposed in the internal groove and expands radially in order to co-operate elastically with an internal face of the internal groove of the oronasal face piece.
A respirator face mask providing physiological protection, comprising:
- an oronasal face piece which is connectable to a respiratory gas source, said oronasal face piece having a semi-flexible lip with an edge designed to position said oronasal face piece on a user's face, wherein the edge of the semi-flexible lip returns toward the center of the oronasal face peace piece and,
- a hygienic protection system which is removably positioned on the oronasal face piece, wherein the hygienic protection system comprises:
- a lip insulation part which provides hygienic protection and is located over an external area of said semi-flexible lip extending up to said edge, and
- a lip securing part located outside the oronasal face piece, and which is elastic and exerts a radially compressing pressure on the oronasal face piece in order to maintain the hygienic protection system on the oronasal face piece,
- wherein the oronasal face piece has a maximum section where the section of the oronasal face piece is maximum, wherein at least a portion of the lip securing part is disposed on a first side of the maximum section and extends around an outer perimeter of the oronasal face piece, and the lip insulation part is disposed on a second side opposite to the first side with respect to the maximum section.
A respirator face mask providing physiological protection, comprising:
- an oronasal face piece which is connectable to a respiratory gas source, said oronasal face piece having a semi-flexible lip designed to position said oronasal face piece on a user's face, said semi-flexible lip having an internal face, and external face and an edge between the internal face and the external face,
- a hygienic protection system removably positioned on said semi-flexible lip and including:
- a first part comprising a hygienic protection part including a filter which is permeable to respiratory gases,
- a second part comprising an internal part in contact with the internal face of the semi-flexible lip,
- a third part comprising an edge part which forms a thin lip and prolongs the internal part,
- a fourth part comprising an external part which also forms a thin lip, wherein the external part prolongs the edge part, faces the internal part, and is in contact with a peripheral portion of the external face of the semi-flexible lip.
A respirator face mask providing physiological protection, comprising:
- an oronasal face piece which is connectable to a respiratory gas source, said oronasal face piece having a semi-flexible lip with an edge designed to position said oronasal face piece on a user's face, wherein the edge of the semi-flexible lip returns toward the center of the oronasal face piece and,
- a hygienic protection system which is removably positioned on the oronasal face piece, wherein the hygienic protection system comprises:
- a lip insulation part which provides hygienic protection and is located over an external area of said semi-flexible lip extending up to said edge, and
- a lip securing part located outside the oronasal face piece, and which is elastic and exerts a radially compressing pressure on the oronasal face piece in order to maintain the hygienic protection system on the oronasal face piece,
- wherein the oronasal face piece has a maximum section where the section of the oronasal face piece is maximum, wherein at least a portion of the lip securing part is disposed on a first side of the maximum section, and the lip insulation part is disposed on a second side opposite to the first side with respect to the maximum section,
- wherein the hygienic protection system further comprises a structural part which is in contact with an internal face of the semi-flexible lip.
