Publication number: 20180078752Abstract: 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: October 11, 2017Publication date: March 22, 2018Inventors: Laurence Gulliver, Michael Paul Ronayne, Charles William Douglas Irving

Publication number: 20180078726Abstract: A user interface convertible between a nasal configuration and an oral configuration. The user interface has a nasal cannula and a mouthpiece. The nasal cannula has a body portion and at least one prong extending from the body portion, the prong being adapted to direct a flow of gas into a nare of a user's nose. The mouthpiece is adapted to engage the mouth of the patient and direct a flow of gas into a user's mouth. In the nasal configuration the prong of the nasal cannula is adapted to direct a flow of gases into a nare of the patient. In the oral configuration, the nasal cannula is engaged with the mouthpiece such that a gases flow is provided to at least the mouth of the user.Type: ApplicationFiled: March 31, 2016Publication date: March 22, 2018Inventors: Michael Robert Barraclough, Matthew Jon Payton, Callum James Thomas Spence, Laurence Gulliver, Samantha Dale Oldfield, Dexter Chin Lun Cheung, Geraldine Frances Keogh, Milanjot Singh Assi, Alicia Jerram Hunter Evans, Craig Kari White

Publication number: 20170281051Abstract: 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: ApplicationFiled: September 4, 2015Publication date: October 5, 2017Inventors: 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
