20120152255 | PAP SYSTEM - Systems, devices and methods of use adapted for treatment of respiratory disease or sleep disordered breathing include a patient interface ( | 06-21-2012 |
20130000647 | RESPIRATORY RESISTANCE SYSTEMS AND METHODS - A patient interface includes a mask configured to communicate with at least one airway of a patient, the mask including at least one aperture ( | 01-03-2013 |
20130160766 | METHODS AND APPARATUS FOR PREVENTING RAINOUT - Components for a respiratory treatment apparatus that is capable of providing a humidified respiratory treatment permit a reduction in condensation in a patient interface and/or its gas delivery tubing. In some embodiments, a rainout valve that may be an integrated component of a humidifier output aperture, or coupled thereto, may reduce condensation with a vapor barrier operable to selectively block and permit humidified gas transfer from the humidifier. For example, the barrier may be operable to open in response to a flow of pressurized breathable gas that may be generated by a flow generator of the respiratory treatment apparatus. In the absence of such a generation of pressurized flow, the barrier may prevent a transfer of the humidified gas such as into a conduit for a patient interface by retracting to a closed position. Example vapor barriers may include a resilient membrane, cover, bellows, flap, shutter or other suitable valve. | 06-27-2013 |
20130226020 | ACOUSTIC DETECTION MASK SYSTEMS AND/OR METHODS - Certain examples described herein relate to acoustic detection mask systems and/or methods. In certain examples, an acoustic detection mask system is provided. An example acoustic detection mask system includes a mask having a microphone located therein or thereon. The microphone is connected to a data logger that is configured to capture vibrations and/or sounds registered by the microphone. The data logger may store such information in a computer readable storage media thereof for subsequent analysis, e.g., via a computer program accessing such data after the data logger is connected to a separate computer system. The microphone may be positioned and the data analyzed so as to determine differences between oral and nasal breathing, as well as sleep-disordered breath and/or snoring. Such components may be provided as a part of a system or in any suitable combination or sub-combination. Associated methods also are described herein as a part of the technology. | 08-29-2013 |
20130324788 | METHOD AND APPARATUS FOR TREATMENT OF SLEEP DISORDERS - A system for therapy may include a mask ( | 12-05-2013 |
20140020684 | RESPIRATORY BREATHING APPARATUS - A respiratory apparatus comprising a base and removable chamber, wherein the chamber is configured to hold a supply of water and include a blower arrangement adapted to provide a supply of pressurized air or gas to the supply of water. In certain embodiments the respiratory apparatus includes a split motor, wherein the stationary components are located within a base and the rotating portions are located within a chamber. | 01-23-2014 |
20140305431 | EXCHANGER ASSEMBLY FOR RESPIRATORY TREATMENT - An exchanger conduit permits temperature and/or humidity conditioning of a gas for a patient respiratory interface. In an example embodiment, a conduit has a first channel and a second channel where the first channel is configured to conduct an inspiratory gas and the second channel configured to conduct an expiratory gas. An exchanger is positioned along the first channel and the second channel to separate the first channel and the second channel. The exchanger is configured to transfer a component (e.g., temperature or humidity) of the gas of the second channel to the gas of the first channel. In some embodiments, an optional flow resistor may be implemented to permit venting at pressures above atmospheric pressure so as to allow pressure stenting of a patient respiratory system without a substantial direct flow from a flow generator of respiratory treatment apparatus to the patient during patient expiration. | 10-16-2014 |
