Publication number: 20200338293Abstract: Nasal cannulas for providing respiratory therapy to patients can have a body, two prongs extending from the body, and a gases inlet on one side of the body. There can be a throttle or internal localized reduction in the cross-sectional area of a cavity defined by the internal walls of the cannula body in between the prongs. In at least some arrangements, the throttle can partially or substantially fully equalize flow between the prongs of the cannula.Type: ApplicationFiled: July 7, 2020Publication date: October 29, 2020Inventors: Laurence GULLIVER, Mark Thomas O'CONNOR

Patent number: 10722143Abstract: The present disclosure relates to determining a corrected exhaled gas measurement during high flow respiratory therapy. Measuring exhaled gas concentration during high flow respiratory therapy is difficult and inaccurate due to a phenomenon known as flushing. The high flows delivered to the patient flush the dead space in the conducting airways, which causes a dilution effect that results in underestimated or overestimated exhaled gas measurement depending on the gas composition delivered by the high flow system. This can lead to incorrect clinical measurements and diagnoses. Various algorithms are disclosed herein to account for the dilution effect caused by flushing, allowing for the method of measuring gas concentrations to still be used accurately for clinical measurements.Type: GrantFiled: September 4, 2015Date of Patent: July 28, 2020Assignee: Fisher & Paykel Healthcare LimitedInventors: Alicia Jerram Hunter Evans, Callum James Thomas Spence, Craig Karl White, Geraldine Keogh, Matthew Jon Payton, Laurence Gulliver, Milanjot Singh Assi, Samantha Dale Oldfield, Laith Adeeb Hermez

Patent number: 10688268Abstract: A component useable with one or more tube comprises a body engageable with one or more external surface recesses of the one or more tubes. The component has a pair of jaws extending from the body for gripping an item. The component is configured, such that, in use, in a first orientation of the body relative to the respective tube(s) recesses, the component is movable along a length of the tube(s); and, in a second orientation of the body relative to the respective tube(s) recesses, the component is resistive to movement along a length of the tube(s).Type: GrantFiled: December 20, 2018Date of Patent: June 23, 2020Assignee: Fisher & Paykel Healthcare LimitedInventors: Laurence Gulliver, Michael Paul Ronayne, Puqing Zhang, Andrew Paul Maxwell Salmon, Rex Gordon Faithfull

Publication number: 20200054851Abstract: This invention relates to a headgear component as a part of a headgear. The component comprising a backstrap, a first ear loop extending from one end of the backstrap, the first ear loop following a path defining a first ear opening, and a second ear loop extending from another end of the backstrap, the second ear loop following a path defining a second ear opening. A first pair of connection zones is on the first ear loop, each connection zone spaced an equal distance from the backstrap and spaced from each other, and a second pair of connection zones on the second ear loop, each connection zone spaced an equal distance apart from the backstrap and spaced from each other. A connection zone of the first pair and a connection zone of the second pair are on a first side of the backstrap, and a connection zone of the first pair and a connection zone of the second pair are on a second (other) side of the backstrap, wherein the headgear component is substantially of a symmetrical shape.Type: ApplicationFiled: September 25, 2019Publication date: February 20, 2020Inventors: Laurence Gulliver, Michael Paul Ronayne, Charles William Douglas Irving

Publication number: 20190321617Abstract: In an embodiment, a connector or connector assembly for attaching a nasal cannula with a gas delivery hose includes a sensor port for a sensor probe positioned near an end of a nasal cannula, which can allow the sensor probe to be placed closer to the patient's nostrils than previous connector parts allowed. The connector can be configured to advantageously allow the nasal cannula to rotate relative to the gas delivery hose, thereby allowing a patient or healthcare provider to untangle or otherwise straighten the hose or the cannula. The connector assembly can be configured to automatically align locking protrusions on a first component with locking recesses on a second component, where insertion of the second component within the first component causes the second component to rotate relative to the first component, thereby aligning the locking protrusions with associated locking recesses.Type: ApplicationFiled: May 23, 2019Publication date: October 24, 2019Inventors: Laurence Gulliver, Michael Paul Ronayne, Charles William Douglas Irving
