Various embodiments provide a speech diaphragm module comprising: a body; a lid secured to the body to form an enclosed volume therein; a resilient film secured within the enclosed volume along an attachment join formed around a periphery of the resilient film; and a tensioning feature arranged to displace an operative portion of the resilient film relative to the attachment join to apply a tension across the resilient film. Some other embodiments provide a method of manufacturing a speech diaphragm module, a respirator, and a kit of parts for forming a speech diaphragm module.

Masks for various uses and methods for manufacture thereof, including masks for use in continuous positive air pressure (CPAP) therapies. An example includes a mask having a first, relatively softer material for contact with the face of the user, and a second, relatively harder or more structural material used away from the face of the user, with a gradient therebetween. The mask can be produced by additive manufacturing to avoid a discernible boundary between the first and second materials.

The mask can be produced by additive manufacturing to avoid a discernible boundary between the first and second materials. The mask may include a foam element, which can be removable for replacement in some examples, for contacting the patient's skin.

A mask configured to deliver pressurized airflow according to an exemplary aspect of the present disclosure includes, among other things, a central portion configured to surround a nose of a patient, a first pair of wings projecting from opposite sides of the central portion, and a second pair of wings projecting from opposite sides of the central portion. The disclosed mask has particular benefits to pre-term infants. A system and method are also disclosed.

A respiratory apparatus may employ ultrasonic welds. The ultrasonic welding may be used to join a variety of headgear, mask and accessory components. This process may enhance comfort, fit and/or performance of the joined components and/or overall mask assembly. A component may be a single layer component such as a textile or fabric, or a composite or multiple layer component such as fabric and foam composites, or outer fabric layers and inner spacer fabrics. Further, a component may be a strap, some other headgear component, a mask component, an accessory component or the like.

A molded face mask for treating a user's face, the molded face mask comprising a rigid, inflexible polycaprolactone body molded to the user's face, the body comprising: i) two opposed, slightly tapered end portions; ii) a generally straight lower edge; and iii) an upper edge having a concave portion disposed approximately half-way along a length of the upper edge. A kit for providing therapeutic relief and reducing redness and bumps associated with facial shaving.

A method of determining facial metrics of a person includes: receiving a request that the person requires a mask; navigating an autonomously operable vehicle to the person using at least one imaging device; capturing a number of images of the person using the at least one imaging device; and determining facial metrics of the person from the number of images. The method may be further employed in a method for identifying a mask for the person which further includes determining a mask for the user from the facial metrics; and identifying the mask to the person.

A molded face mask for treating a user's face, the molded face mask having a rigid, inflexible body molded to the user's face, and a way to couple the molded face mask to the user's face. The body has a top edge, a bottom edge, a left side edge and a right side edge and at least one nostril opening disposed proximate the user's nostrils.

A breathing mask device, a sealing lip device for a breathing mask device, a molding tool and a method for producing a corresponding breathing mask device and sealing lip device are described. Also disclosed are ways that make it possible to create a breathing mask device that, with sufficiently strong tightness is distinguished by particular wearing comfort and which moreover can be produced advantageously in times of industrial production standpoints. A breathing mask device for administering a breathable gas is provided and includes a body structure that is sealed against a contact surface of a user's face, a sealing lip device that in combination with the body structure in part defines a breathing mask interior, a gel structure for at least intermittent and partial transmission of the retention forces, acting on the body structure, to the user's face area, and a gel material defining the gel structure is received in a gel receiving chamber defined at least in part by an elastically deformable receiving wall.

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.
