Publication number: 20240017033Abstract: An interface assembly includes an interface, such as a mask, that is secured to a head using a headgear assembly. The headgear assembly can include at least one halo portion and a plurality of straps. The headgear assembly can include both a front halo portion and a rear halo portion. In some arrangements, the headgear and mask define an adjustable closed loop. In some arrangements, the headgear can include one or more rigid portions that contact the user's face to at least partially isolate a seal of the mask from tightening forces applied to the headgear. In some arrangements, the mask is an oral-nasal mask and the headgear applies a force to the mask comprising an upward force component. In some arrangements, the headgear can be contoured to the user's head.Type: ApplicationFiled: June 26, 2023Publication date: January 18, 2024Inventors: Peter David Alexander Bearne, Roheet Patel, Kirstin Elizabeth Middelkoop, Fadi Karim Moh'd Mashal, Michael John Henri Cox, Blair Raymund Dadson Murphy

Publication number: 20230086237Abstract: A patient interface can have features improving the comfort of use by reducing the perceived pressure of a nose-contacting cushion of the patient interface against the nose. The patient interface can have rigid headgear connection elements connectable to a frame of the respiratory interface. The rigid headgear connection elements can be shaped to reduce the force of the cushion against the nose. Headgear for a patient interface can also have features improving the stability of headgear of the head. The headgear can have a relatively rigid framework and a relatively pliable overlay covering the framework. The framework can have apertures defining a front portion to be positioned below or near the cheekbones, a rear portion to be positioned over the sides of the head around the ears, and a top portion to extend upward along the head towards the crown.Type: ApplicationFiled: May 5, 2022Publication date: March 23, 2023Inventors: Peter David Alexander Bearne, Blair Raymund Dadson Murphy, Kirstin Elizabeth Middelkoop, Fadi Karim Moh'd Mashal, Michael John Henri Cox, Sophie Kathryn Randles, Mark Arvind McLaren, Ronan Leahy, Roheet Patel

Publication number: 20220362502Abstract: This disclosure provides a directional adjustment unit for a headgear for a respiratory mask The directional adjustment unit provides an increased resistance to extension of one or more straps of the headgear when the headgear is under tensile forces, as compared to a lower resistance to retraction of the one or more headgear straps. The directional adjustment unit comprises a movable frictional engagement member comprising an aperture, wherein the aperture is arranged to receive a filament of a strap of the headgear therethrough, wherein the frictional engagement member in a first configuration provides a disengaged or pre-activated configuration with respect to the filament, and in a second configuration provides an engaged configuration with respect to the filament. Features are provided which improve the operation of such a directional adjustment unit.Type: ApplicationFiled: November 13, 2020Publication date: November 17, 2022Inventors: Vitaly KAPELEVICH, Christopher Gareth SIMS, David Monroy FELIX, Blair Raymund Dadson MURPHY, Matthew Robert Geoff SLIGHT, Vidhi Jayeshkumar SHAH, Kavyn MANIKKAM
