A headgear or headgear segments are manufactured to shape thereby producing little or no waste material. Such headgear or headgear segments (components) may comprise a unitary, substantially seamless structure. Techniques such as knitting, braiding, crocheting, and 3D printing may be used to produce the headgear. As a result, the manufacturing process may have reduced steps, the amount of material waste may be reduced, and there are virtually no seams in the headgear between adjoining sections, thereby resulting in headgear with enhanced comfort.

A mask system and an air delivery conduit for use in the treatment of respiratory disorders. The air delivery conduit may comprise a textile having an airtight arrangement. A support structure may be provided to the conduit to provide form.

A nasal interface uses asymmetrical nasal delivery elements to deliver an asymmetrical flow through the interface to both nares or to either nare, and a mouthpiece may be inserted to maintain a leak, to improve dead space clearance in the upper airways, decrease peak expiratory pressure, reduce noise, increase safety of the therapy for smaller patients and reduce resistance in the interface allowing desired flow rates to be achieved at reduced motor speeds of associated flow generating devices. Different forms of fittings, such as sleeves or inserts can be attached to nasal delivery elements to improve or optimise the therapeutic effects of nasal high flow. It may allow high pressures to be achieved at lower flow rates, reduce noise, improve patient comfort and efficiently clear anatomical dead space.

A customizable mask including a conforming seal is configured to utilize the physical process of granular jamming to enable it to adapt to a wide range of facial geometries. The mask may include a frame having a perimeter and a conduit connection, a conforming seal positioned along the perimeter of the frame. The conforming seal may include a sealing surface and a connecting surface, the connecting surface configured to mate with the perimeter of the frame, and the sealing surface configured to conform to a users' face. The conforming seal may further include an outer casing, granular material contained within the outer casing, and a vacuum connection. The mask may also include a similarly configured conforming frame. Further disclosed are methods of forming such masks.

A face mask (also called full face) for respiratory therapy, in particular for non-invasive mechanical ventilation, has a low value of CO.sub.2 rebreathing. The mask includes a shaped shell to cover at least the mouth, the nose and the eyes of a patient when the mask is worn, and includes, on said shaped shell an inlet fitting for the connection to a pipe through which a ventilation apparatus supplies the mask with a mixture of air and oxygen, and an outlet fitting, separate from said inlet fitting, for the discharge of air exhaled by the patient. With this arrangement, the mask allows drastically reducing the phenomenon of carbon dioxide rebreathing, which is very harmful for the patient subjected to ventilation.

This disclosure relates to a mask which delivers pressurized airflow to a patient. The mask includes a central portion and a wing projecting from the central portion. The wing is configured to adhere to a patient's cheek.

A patient interface includes a plenum chamber, a seal-forming structure, and a positioning and stabilising structure to provide a force to hold the seal-forming structure in a therapeutically effective position on a patient's head. The positioning and stabilizing structure includes a superior strap portion, an inferior strap portion, and a posterior connecting strap portion connected to or formed integrally with the superior strap portion and the inferior strap portion. The posterior connecting strap portion is constructed from a mesh material that is different than the material used to construct the superior strap portion and the inferior strap portion. The posterior connecting strap portion has a greater stretch capability than the superior strap portion and a lesser stretch capability than the inferior strap portion. The stretch capabilities allow the positioning and stabilizing structure to be removable from the patient's head when the loop engages the connection portion.
