Patent number: 11826506Abstract: A method for controlling operation of a CPAP apparatus. The apparatus has a blower, a patient interface, an air delivery conduit for delivering air from the blower to the patient interface, a sensor for determining the pressure in the patient interface, and a control mechanism that causes air to be delivered at a desired pressure to the patient interface and that detects transitions between inhalation and exhalation of a respiratory cycle of a patient in order to synchronise the blower output with the patient's efforts. In one form the CPAP apparatus provides pressure in accordance with a bi-level waveform with at least one characterising parameter of the waveform being automatically adjusted in accordance with indications of sleep disordered breathing. The indications of sleep disordered breathing can be one or more of snoring, apnea, hypopnea, and flow limitation.Type: GrantFiled: July 23, 2019Date of Patent: November 28, 2023Inventors: Robert Douglas, Anthony John Ujhazy, Glenn Richards, Mark David Buckley, Klaus Henry Schindhelm

Publication number: 20230172610Abstract: Devices, systems, and methods for combinatorial treatment of a condition with an implantable damping device and biologic therapeutic agent are disclosed herein. Methods for treating one or more effects of the condition, such as a neurological condition, include providing the implantable damping device and at least one other therapy, such as a biologic therapeutic agent, that treats the condition to the patient. The implantable damping device includes a flexible damping member and an abating substance and can be placed in apposition with a blood vessel. The flexible damping member forms a generally tubular structure having an inner and an outer surface, the inner surface formed of a sidewall having a partially deformable portion. The abating substance is disposed within the partially deformable portion and moves longitudinally and/or radially within the partially deformable portion in response to pulsatile blood flow.Type: ApplicationFiled: April 2, 2021Publication date: June 8, 2023Inventors: David Stephen Celermajer, Zoran Milijasevic, Anthony John Ujhazy, Mark Carnegie, Rachel Ashley Levin

Patent number: 10856802Abstract: Methods and apparatus for assessing the condition of and treating patients for heart failure by the delivery of continuous positive airway pressure are disclosed. Treatment of obstruction due to reflex vocal cord closure often experienced by heart failure patients is distinguished from treatment of upper airway obstruction typically associated with Obstructive Sleep Disorder. Treatment may also be implemented by delivering synchronized cardiac pressure oscillations superimposed on a respiratory pressure level to provide assistance for the heart. Heart treatment pressure dose indicator may be calculated for prescribing and monitoring the delivery of treatment. The apparatus may also generate data to track heart failure condition that may be indicative of the degree of severity of heart failure based upon breathing patterns to assist in the diagnosis and management of heart failure patients.Type: GrantFiled: February 8, 2016Date of Patent: December 8, 2020Inventors: Anthony John Ujhazy, Jonathan Caldwell Wright, Glenn Richards, David John Bassin, Michael Berthon-Jones

Patent number: 8622057Abstract: The invention features methods and apparatus for the treatment of asthma patients. A controlled supply of breathable air delivered to a patient interface or mask (4) is controlled for patient comfort to maintain a steady pressure level in a range 2 to 4 cm H2O to accommodate patient respiration. The breathable air is cleaned by a high efficiency particulate arresting filter (10) to remove allergens from the air supply. The apparatus may be programmed to automatically detect asthma-related symptoms such as an asthma attack by analyzing the respiratory flow of the patient. In response to the detection of such an attack, the apparatus may provide an audible warning or if configured with a treatment delivery module (14A, 14B), the device may administer a therapeutically effective dose of a drug or substance, for example, a broncho-dilator, to alleviate the patient's breathing difficulty. Preferred mask designs allow for proper CO2 washout to accommodate the low pressures supplied to the mask and prevent asphyxia.Type: GrantFiled: February 15, 2002Date of Patent: January 7, 2014Assignee: ResMed LtdInventors: Anthony John Ujhazy, Jonathan Caldwell Wright, Joanne Elizabeth Drew, Michael Berthon-Jones
