Publication number: 20110162647Abstract: A respiratory treatment apparatus provides respiratory treatment with improved power management control to permit more efficient power consumption and power supply units, such as battery powered operation. In one embodiment, power management prioritizes the flow generator (104) over other accessories such as the heating elements (111, 135) of a humidifier (112) and/or a delivery tube. The flow generator may control operations of the heating elements as a function of a detected respiratory cycle. For example, the timing of operation of the heating elements may be interleaved with the portion of an inspiratory phase of the respiratory cycle to permit the flow generator to operate during a peak power operation without a power drain or with a lower power drain from these components. Operations of distinct sets of components of the system (e.g., different heating elements) may also be interleaved to prevent simultaneous peak power operations.Type: ApplicationFiled: September 7, 2009Publication date: July 7, 2011Applicant: RESMED LIMITEDInventors: Ronald James Huby, Andrew Roderick Bath, John David Oates

Patent number: 7958890Abstract: A dry powder inhaler has a dispersion chamber containing beads. A dose of dry powder is released into the chamber, or into an inlet tangentially joining into the chamber. As the patient inhales on a nosepiece or mouthpiece, air moves circularly through the dispersion chamber to drive the beads. The beads roll, bounce, and collide repeatedly with the drug particles on the chamber surfaces or on the beads. The smaller active drug particles are separated from larger carrier particles and from each other, and a powder aerosol is created and inhaled by the patient. The beads are preferably lightweight, so that they can be rapidly accelerated and moved, even with nominal inspiration. The flow resistance of the inhaler is also reduced via the beads, allowing greater airflow and powder dispersion, without any increased effort by the patient.Type: GrantFiled: December 4, 2008Date of Patent: June 14, 2011Assignee: Quadrant Technologies LimitedInventors: Andrew W.

Patent number: 6708688Abstract: A metered dosage inhaler system with variable positive pressure settings has a hollow housing with a front portion with a cylindrical protruding user adaptor portion, a top face having apertures, a user controlled air resistance dial, a bottom face having a handle/input, and a cylindrical downwardly extending hollow handle portion. The first end of the handle portion is adapted to form an airtight removable coupling with the handle/input adaptor. An end piece with holes is adapted to couple to the second end of the handle portion. A spherical ball has a diameter less than that of the handle portion and removably rests in the handle portion. The ball rises in response to a vacuum caused by a,patient. A mouth piece portion has a cylindrical first portion removably coupled to the adapter portion and a tapered second portion adapted to fit comfortably within the mouth of a patient.Type: GrantFiled: December 11, 2001Date of Patent: March 23, 2004Inventors: Darren Rubin, Howard Rubin
