Publication number: 20240285883Abstract: A positive exhalation pressure device (1) is described. The device (1) comprises a housing (2) having an annular chamber (5), a chamber inlet (6) configured to permit air into the chamber, a chamber outlet (7) configured to permit air out of the chamber, and a mouthpiece (8) in fluid communication with the chamber inlet. A movable body such as a ball (3) is disposed in the housing within the annular chamber and configured to revolve around the annular chamber in response to flow of air through the chamber from the chamber inlet to the chamber outlet. The movable body is configured to at least partially block the chamber outlet as it revolves around the annular chamber causing cyclical fluctuations in airflow resistance.Type: ApplicationFiled: March 7, 2024Publication date: August 29, 2024Applicant: Solopep LimitedInventors: Kevin J. O'SULLIVAN, Leonard W. O'SULLIVAN, Colum DUNNE, Barry LINNANE, Deirdre McGRATH

Patent number: 8774898Abstract: The present invention relates to a method of characterising tissue function in a subject in need of such characterization. The method comprises performing an imaging technique, on a voxel defined within a tissue space of interest, wherein image data is generated over a time period during which the subject inhales gases with at least two different partial pressures of a paramagnetic gas. A compartmental model algorithm is applied to the image data generated for the voxel to provide information on metabolic function of the tissue.Type: GrantFiled: April 17, 2009Date of Patent: July 8, 2014Assignee: BIOxyDyn LimitedInventors: Deirdre McGrath, Geoffrey Parker

Patent number: 8255036Abstract: The present invention relates to a method of characterizing lung function in a subject in need of such characterization. The method comprises performing an imaging technique, on a voxel defined within a lung space of interest. Image data is generated over a time period during which the subject inhales gases with at least two different partial pressures of a paramagnetic gas. A compartmental model algorithm is applied to the image data generated for the voxel to provide information on ventilation, diffusion and perfusion of a lung. The paramagnetic gas is preferably Oxygen. The imaging technique is preferably Oxygen Enhanced Magnetic Resonance Imaging (OE-MRI).Type: GrantFiled: April 18, 2008Date of Patent: August 28, 2012Assignee: The University of ManchesterInventors: Deirdre McGrath, Geoffrey Parker
