Abstract: A breathing mask includes a relatively rigid shell and an elastomeric sealing lip mounted to the relatively rigid shell. The elastomeric sealing lip has a contact zone configured to bear against the face of the person. The elastomeric sealing lip further includes a nose bridge region, a first nostril region and a second nostril region. The nose bridge region has a first zone of lower load-bearing capability. The first nostril region has a first zone of higher load-bearing capability. The second nostril region has a second zone of higher load-bearing capability. The first zone of lower load-bearing capability has a lower load-bearing capability than the first and second zones of higher load-bearing capability. In addition, the contact zone is configured to pivot about an articulation axis that extends through the first and second nostril regions.

Abstract: An elastomeric cushion for a breathing mask is configured for sealed delivery of a flow of breathable gas at a positive pressure with respect to ambient air pressure to an entrance of a patient's airways including at least an entrance of the patient's nares. The elastomeric cushion includes a sealing lip with an elastomeric wall configured to form a seal with the patient's face. An elastomeric wall thickness of the sealing lip is varied so that when the sealing lip sealingly engages the patient's face, a portion of the seal at the patient's nose bridge is formed by a relatively thin-walled portion of the sealing lip and other portions of the seal are formed by relatively thick portions of the sealing lip.

Abstract: A breathing mask includes an elastomeric cushion with a sealing lip having an outer engagement surface configured to sealingly abut against the patient's face. The sealing lip has a plurality of zones. A first zone has an elastomeric wall and includes a portion of the elastomeric cushion adapted to abut against a bridge of a patient's nose. A second zone has an elastomeric wall and includes a portion of the elastomeric cushion adapted to abut against the patient's face at a location opposite the first zone. A pair of intermediate zones include portions of the elastomeric cushion adapted to abut against the patient's face between the first and second zones and have relatively thick elastomeric walls compared to the elastic walls of the first and second zones so that the pair of intermediate zones has a higher load-bearing capability than the first and second zones.

Abstract: A sealing lip device for a breathing mask includes a receiving opening for receiving at least the nose tip region of a mask wearer, a sealing lip which is formed from an elastomeric material and which surrounds the receiving opening and which is configured to cross the bridge of the nose and which has a contact zone provided for bearing against the face of a mask wearer in use. The sealing lip is elastically and yieldingly arranged in such a way that a first sealing lip zone which in use seals the region of the bridge of the nose has a higher degree of flexibility than a second sealing lip zone which in use is adjacent to at least one of the nostrils and the upper lip of the mask wearer in the application position of the breathing mask. The sealing lip includes a folding bellows structure that suspends the sealing lip in the region of the first zone provided for sealing of the region of the bridge of the nose. The folding bellows structure includes a fold indentation having zones of differing wall thickness.

Abstract: The invention relates to a sealing lip device for a respiratory mask, to a respiratory mask per se and to a method and mould for producing the same. According to the invention, the respiratory mask has an orifice (2) for receiving at least the nose tip of the mask wearer and a sealing lip (3) consisting of an elastomeric material, which surrounds the orifice and crosses the bridge of the nose. Said sealing lip has a supporting zone which lies against the face of a mask wearer. The elastic pliability of the sealing lip (3) is such that the sealing lip zone (a) which seals the area around the bridge of the nose has a greater pliability than the sealing lip zone (b1, b2, c) which lies adjacent to the nostrils and/or the upper lip of the mask wearer, when the mask is applied to the face of the latter. From a production method viewpoint, the synthetic material is introduced in two separate injection-moulding steps, a support structure (4) with thick walls being preferably configured in the first step.
