Publication number: 20190111228Abstract: An expiratory limb for a breathing circuit includes an enclosing wall defining a flexible singular expiratory flow passage between an inlet and an outlet and bounding the flexible singular expiratory flow passage and ambient air. The expiratory limb includes one or more regions of the enclosing wall that made from a material that allows passage of water vapor without allowing passage of liquid water, thereby forming a water vapor flow path from the flexible singular expiratory flow passage to the ambient air through the material. The expiratory limb is configured to allow diffusion of water vapor along the flexible singular expiratory flow passage and dry the flow of expiratory gases between the inlet and the outlet.Type: ApplicationFiled: December 6, 2018Publication date: April 18, 2019Inventors: Daniel John Smith, Gavin Walsh Milar, Kevin Blake Powell, David Peter Baldwin

Publication number: 20190111229Abstract: A wye connector has a patient coupling end. The patient coupling end has a first connector surface and a second connector surface. The first connector surface has a first diameter at an axial location along the patient coupling end. The second connector surface has a second diameter at the same axial location along the patient coupling end. The first diameter is larger than the second diameter. The second connector surface projects axially outward beyond the first connector surface.Type: ApplicationFiled: November 1, 2018Publication date: April 18, 2019Inventors: Madeleine Bess Martin, David Robert Kemps

Publication number: 20190111232Abstract: A respiratory valve, such as a positive end expiratory pressure valve, permits pressure control for respiratory apparatus such as a ventilator or positive airway pressure device. The valve may include a flexible gas passage cover. The cover may be configured with a first side surface to operatively block and open an aperture of the gas passage at a valve seat to respectively prevent and permit gas flow through the aperture defined by the valve seat. The cover may include a second side surface opposite the first surface. The second surface may include at least one drop section forming a reduction in thickness of the cover between the first surface and the second surface. The first surface may include a coating to reduce friction of a membrane material of the first surface. The rim of the valve seat may comprise a variation in height relative the flexible cover.Type: ApplicationFiled: May 16, 2017Publication date: April 18, 2019Applicant: ResMed LimitedInventors: Liam Holley, Simon Robert Cork, Sebastien Deubel

Publication number: 20190111233Abstract: A method for producing a distal-end assembly of a medical device, the method includes disposing a first layer on at least part of a given section among one or more sections of a flexible substrate. At one or more selected locations on the given section, which are to serve as electrodes on the distal-end assembly of the medical device, a second layer is disposed so that, when brought into contact with tissue, the second layer has a reduced impedance for transferring electrical signals to or from the tissue at a predefined frequency range, relative to the first layer. The given section is shaped to form the distal-end assembly.Type: ApplicationFiled: October 18, 2017Publication date: April 18, 2019Inventors: CHRISTOPHER THOMAS BEECKLER, Joseph Thomas Keyes

Publication number: 20190111235Abstract: A multi-lumen catheter hub with a plurality of attachment members is provided. The catheter hub allows removal of the external fluid connections of an elongated percutaneous medical article, such as a catheter or cannula. The percutaneous medical article suitably contains a clamping mechanism that prevents fluid movement within the intraluminal space of the percutaneous medical article when the fluid connections are removed. The attachment members are single-use, disposable components that provide intraluminal access for a variety of medical articles and are removed following clinical use. Retaining the catheter transition allows the catheter to be secured using methods common to the art.Type: ApplicationFiled: April 26, 2017Publication date: April 18, 2019Inventor: Cameron C. Jones
