Abstract:
A pad for a forehead support includes an outer wall having a first side configured to engage a user's forehead and a second side having engaged surfaces configured to rest against engaging surfaces of the forehead support; at least one retaining wall provided between the first side and the second side; and at least one retained portion configured to be retained by a retainer formed on the forehead support, wherein a space is defined between the outer wall and the engaged surfaces. The space has a substantially constant cross sectional profile, and the outer wall, the at least one retaining wall, and the engaged surfaces are formed of a deformable elastomeric material. Deformation of the pad occurs by deflection of at least the outer wall and the at least one retaining wall.
Abstract:
A connector system for use with an apparatus that delivers a supply of pressurized breathable air to a patient includes an air delivery conduit including an auxiliary conduit. The air delivery conduit and auxiliary conduit have a first end and a second end. A connector is provided to at least one of the first and second ends. The connector includes an inner tubular wall and an outer tubular wall surrounding the inner tubular wall and being concentric with the inner tubular wall. The inner and outer tubular walls define first and second passages that are isolated from one another. One of the first and second passages is configured to communicate with the air delivery conduit and the other of the first and second passages is configured to communicate with the auxiliary conduit.
Abstract:
Systems, devices and methods of use adapted for treatment of respiratory disease or sleep disordered breathing include a patient interface (10) adapted to be secured to and sealed against a portion of a patient's face, in use. A flow generator is adapted to be connected to the patient interface and to be secured by a portion of the patient's body. The flow generator includes a blower (50) adapted to provide pressurized breathable gas to a patient through the patient interface. The blower is adapted to be at least partially vibrationally isolated from the patient's body by at least one dampening system (49) or device. The dampening device or system is adapted to reduce the amount of transmitted vibration received by the patient. A PAP system includes a patient interface including sealing arrangement (30) adapted to form a seal with the patient's nose and/or mouth and headgear (40) to support the sealing arrangement in position on the patient's head. A blower is structured to generate a supply of pressurized air. The blower is supported by the patient interface on the patient's head and in communication with the patient interface. The headgear forms one or more ducts (42) to communicate pressurized air from the blower to a breathing cavity defined by the sealing arrangement.
Abstract:
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.
Abstract:
A headgear assembly for a mask system includes a two-dimensional first headgear section and a two-dimensional second headgear section, wherein the two-dimensional first and second headgear sections are attached to one another to form a three-dimensional anatomically-shaped headgear assembly.
Abstract:
A method of operating a device for treating sleep disordered breathing (SDB), wherein the device provides continuous positive airway pressure during sleep, includes determining whether treatment pressure at the patient interface is below a desired value, in response to the determining, increasing pressure generated by the flow generator, in response to the increasing, making a determination that the increase in flow generator pressure has resulted in less than a desired increase in treatment pressure at the patient interface, and in response to the determination, reducing or inhibiting further increase of the flow generator pressure.
Abstract:
Systems and/or methods for assessing the sleep quality of a patient in a sleep session are provided. Data is collected from the patient and/or physician including, for example, sleep session data in the form of one or more physiological parameters of the patient indicative of the patient's sleep quality during the sleep session, a subjective evaluation of sleep quality, etc.; patient profile data; etc. A sleep quality index algorithm, which optionally may be an adaptive algorithm, is applied, taking into account some or all of the collected data. Sleep quality data may be presented to at least the patient, and it may be displayed in any suitable format (e.g., a format useful for the patient to be appraised on the progress of the treatment, a format useful for a sleep clinician to monitor progress and/or assess the effectiveness of differing treatment regimens, etc).
Abstract:
A respiratory mask assembly for delivering breathable gas to a patient includes a frame having a front surface and a rear surface, opposite the front surface, and adapted in use to face the patient. The frame defines an inner wall and an outer wall extending from the rear surface, the inner and outer walls being spaced to define a channel therebetween. A cushion is removably attachable to the frame such that the cushion and frame are repeatably engagable with and disengagable from one another. The cushion includes a side wall to be inserted into the channel of the frame, the side wall having a first interlocking surface that engages a second interlocking surface provided in the channel when the cushion and frame are engaged with one another. The first and second interlocking surfaces interlock with one another to removably attach the cushion to the frame.
Abstract:
A cushion for a respiratory mask assembly includes a breathing chamber forming portion and a face contacting portion formed in one piece of an elastomeric material, and a gusset portion including one or more folds. The breathing chamber forming portion includes a mask interior breathing chamber and the face contacting portion is structured to engage a patient's face. The gusset portion is structured to provide flexibility to the face contacting portion. The breathing chamber forming portion includes a front side of the mask and the face contacting portion includes a rear side of the mask. The breathing chamber forming portion, when provided to a mask frame, includes an exterior surface exposed at the front side of the mask.
Abstract:
A mask system for use between a patient and a device to deliver a breathable gas to the patient includes a mouth cushion, a pair of nasal prongs, an elbow, and a headgear assembly. The mouth cushion is structured to sealingly engage around an exterior of a patient's mouth in use, and the pair of nasal prongs are structured to sealingly communicate with nasal passages of a patient's nose in use. The elbow delivers breathable gas to the patient. The headgear assembly maintains the mouth cushion and the nasal prongs in a desired position on the patient's face. The headgear assembly provides a substantially round crown strap that cups the parietal bone and occipital bone of the patient's head in use.
