20110197893 | QUICK RELEASE HEADGEAR STRAP - This invention provides a headgear for a mask assembly including straps for positioning on the head and means to minimise deviation from an optimal mask assembly setting when engaging or disengaging the mask assembly from operative use. Preferably, the disengaging means is a variable-length strap incorporating at least one length delimiter, which may be a hub in the strap or an alternative means which employ friction to remain in place. The strap surfaces may be modified to provide the delimiting means. The strap may incorporate a second delimiting means in moveable engagement with the strap. Preferably, one engagement means is in fixed engagement with the strap. One delimiting means may be a thickened strap portion. However, other means for delimiting the effective strap length may be used. | 08-18-2011 |
20110066063 | Respiratory Inductive Plethysmography Band - The invention relates to improved apparatus and methods for respiratory inductive plesthysmography. The invention includes apparatus for measuring changes in the circumference of a subject comprising of an energisable conducting wire having two ends, engagement means for engaging said ends to form a gapless conducting loop, the engagement means being in electrical communication with the conducting wire. The relationship between the elements of the apparatus provides a reduced level of noise associated with a measureable signal attributed to the changes in circumference. Signals generated in the apparatus may be processed and communicated through various means for analysis of respiratory effort. A method is disclosed for measuring respiratory effort with a gapless conducting wire energised with current. | 03-17-2011 |
20110011397 | MULTIPLE CHAMBERS MASK - The present invention provides methods and apparatuses for gas delivery, in particular, a mask including at least one porous barrier defining at least two chambers in gaseous communication. The porous barrier may include a plurality of pores, which define a tapered shape. The mask may include a pliable nasal cushion. The invention provides a method for providing pressurised gas to a subject by supplying gas from a pressurised source to a mask, transmitting the gas into a first chamber at a first pressure, transmitting the gas into a second chamber at a second pressure through a plurality of pores, and transmitting the gas from the second chamber through a mask exit. | 01-20-2011 |
20100217133 | ELECTROCARDIOGRAM DERIVED APNOEA/HYPOPNEA INDEX - The present invention provides a method and apparatus for determining the occurrence of apnoeas or hypopneas from ECG signal data alone. The method is carried out by apparatus configured to acquire ECG signals from a sleeping subject, transform the signals to data, and extract ECG features relevant to estimate breathing effort for the determination of respiratory events characteristic of apnoeas and hypopneas. The extracted ECG features are correlates of breathing efforts and are used as surrogate measures of breathing or respiratory events. The method may include calculating an AHI or apnoea/hypopnea index. The method may classify apnoeas into obstructive or central apnoeas. | 08-26-2010 |
20100170510 | WATER RESERVOIR BAFFLE - TThe present invention provides a water reservoir for humidification of the gas delivered by a gas-delivery device. The water reservoir comprises of a container having at least one opening for gas movement, and a means to prevent water escape through the aperture while allowing passage of gas to be humidified and delivered to a subject. Preferably the means to prevent water escape is a baffle. Preferably the baffle is disposed opposite at least a portion of the opening. The baffle may be continuous with a wall of the container. The container may be comprised of a deformable material. | 07-08-2010 |
