| 20080314388 | Flexible forehead support - A respiratory mask includes a mask frame and a forehead support provided to the mask frame. The forehead support includes a base extending from the frame. The base includes a flexible portion along at least a portion of its length including a material and/or physical characteristic that allows the base to flex from an original, unloaded position. | 12-25-2008 |
| 20080314389 | Forehead support for a facial mask - A respiratory mask includes a mask frame, a forehead support provided to the mask frame and including a forehead member, and headgear including at least one strap adapted to connect to the forehead member. The forehead member includes one or more holes configured and positioned to allow at least one strap to form a strap loop that loops around at least a portion of the forehead member and arrange one or more layers of the strap loop between the headgear member and the patient's forehead in use. | 12-25-2008 |
| 20080314390 | AUTO-ADJUSTING MASK STABILIZER - A forehead support for a facial mask is adapted to be moveable between a first position with respect to a frame of the mask and a second position with respect to the frame. The forehead support includes a biasing mechanism that urges the forehead support in the second position. A method of positioning a forehead support with respect to a frame of a patient interface includes positioning the forehead support and patient interface assembly on a face; disengaging a forehead support locking mechanism; allowing the forehead support to move from a first position to a second position; and engaging a forehead support locking mechanism. | 12-25-2008 |
| 20090014007 | PATIENT INTERFACE AND NON-INVASIVE POSITIVE PRESSURE VENTILATING METHOD - A patient interface for use in delivering a flow of breathable gas to an airway of a patient includes a first seal adapted to contact the patient's face and seal a first space between the patient interface and the patient's face at a first positive pressure; and a second seal adapted to contact the patient's face and seal a second space between the patient interface and the patient's face at a second positive pressure. The first seal also seals the first space from the second space. A leak reducing element may be provided on a seal to reduce and/or diffuse leakage of gas. A vacuum line configured to create a negative pressure may be provided in the second space to remove any gas leaking from the first space to the second space. A seal may be connected to a conduit for delivering the flow of gas that is incorporated into a frame of the patient interface. The seal may be inflatable by the flow of breathable gas to pressurize the seal against the patient's face and include a vent that directs the flow of breathable gas to a space between the patient interface and the patient's face. A cuff may be provided over the seal in the nasal bridge region to direct any leakage of the gas flow from the seal in the nasal bridge region in a direction away from the patient's eyes. | 01-15-2009 |
| 20090107508 | RESPIRATORY MASK ASSEMBLY FOR STABILIZING PATIENT INTERFACE - A respiratory mask assembly for delivering a flow of pressurized breathable gas to a patient includes a structure configured to contact a) at least one point on the patient's forehead, b) two points on the patient's temples, the two temple points being on opposite sides of the patient's face, and c) two points on the patient's cheek, the two cheek points being on opposite sides of the patient's face; a frame, being part of the structure, rigidly connected to other elements of the structure and configured to support a cushion in contact with the patient's face; and a plurality of straps connected to the other elements of the structure and configured to hold the frame against the at least one forehead point, the two temple points, and the two cheek points in a fully constrained manner. | 04-30-2009 |
| 20090194101 | RESPIRATORY APPARATUS - A flow generator for generating a flow of pressurized breathable gas includes a cylindrical housing and a motor supported in the housing. The motor has a shaft having a first end and a second end opposite the first end. The shaft is generally coincident with an axis of the motor. A first impeller is attached to the first end of the shaft and a second impeller is attached to the second end of the shaft. A stator directs an air flow from the first impeller back towards the motor axis. The housing includes an inlet adjacent the first end of the shaft having an inlet axis generally coincident with the motor axis and at least one outlet between the first and second impellers. The at least one outlet has an outlet axis generally tangential to the motor axis. An apparatus for delivering a flow of pressurized breathable gas to a patient includes a flow generator and a casing to contain the flow generator. The casing is configured to engage a part of the patient's body, for example the top of the patient's head, and/or to receive a strap adapted to encircle, for example, the patient's arm or chest. The apparatus further includes at least one delivery conduit to convey the flow of pressurized breathable gas and a patient interface to receive the flow of pressurized breathable gas from the at least one delivery conduit and deliver it to the patient's airways. | 08-06-2009 |
| 20110067704 | UNOBTRUSIVE INTERFACE SYSTEMS - An apparatus for delivering a flow of breathable gas to a patient for the treatment of Sleep Disordered Breathing (SDB) that is less obtrusive includes a nasal cannula, cannulae ( | 03-24-2011 |
