Patent number: 10046127Abstract: A methodology and apparatus for determining ventilator settings including an end expiratory pressure setting, pressure swing, resistive unloading and target ventilation for delivering ventilatory support based upon generalized patient ventilation characteristics and/or disease classifications. An apparatus may be programmed with the instructions to accomplish the methodology interactively by prompting the user/physician during setup and calculating settings based upon measurements or input responses. Pre-assigned values associated with ventilation characteristics or disease classifications may be combined with a base pressure value or measured values to provide patient customized settings or adjustments to determine pressure levels for the delivery of ventilatory support.Type: GrantFiled: July 2, 2012Date of Patent: August 14, 2018Assignee: RedMed LimitedInventor: Michael Berthon-Jones

Publication number: 20180169361Abstract: A method, such as in a controller associated with a respiratory therapy device, determines whether high flow therapy is being used by a patient. The method may include determining whether a property of a flow of air being delivered by a respiratory therapy device along an air circuit to an unsealed patient interface contains a significant oscillation within a breathing rate frequency band. The method may also include generating, dependent on the determination, an indication of whether high flow therapy is being used by the patient.Type: ApplicationFiled: March 14, 2016Publication date: June 21, 2018Applicant: RedMed LimitedInventors: Clancy John DENNIS, Liam HOLLEY, Gordon Joseph MALOUF, Dion Charles Chewe MARTIN, Peter WLODARCZYK

Patent number: 9597479Abstract: A system for therapy may include a mask (200) for a patient having a frame, cushion, forehead support and a light (100). The mask is connectable to a respiratory treatment apparatus, such as a flow generator, to receive breathable gas for a respiratory therapy. The light may also be connected to the power system and/or control system of the apparatus. A light may also be included in a module, such as a docking station, for a respiratory treatment apparatus. The lights may be controlled by one or more processors, and may be responsive to detected conditions, to assist with therapy. For example, the light may be turned on at a predetermined time or may be synchronized with the patient's sleep state, to assist in waking up the patient or re-setting the patient's circadian rhythm. Other components, such as sound and aroma generators of the system, may also be controlled for such therapies.Type: GrantFiled: February 10, 2012Date of Patent: March 21, 2017Assignee: RedMed LimitedInventors: Liam Holley, Jeffrey Peter Armitstead, Steven Paul Farrugia, Dinesh Ramanan, Pallavi Gosain

Patent number: 9364627Abstract: A ventilator device delivers ventilatory support to a patient in a back up timed mode when patient respiration is not detected or a spontaneous mode when patient respiration is detected. The timing threshold governing the back-up mode is chosen to deviate from normal expected respiration time for the patient to promote patient initiated ventilation in the spontaneous mode but permit back-up ventilation in the event of apnea. Automated adjustments to the timing threshold during the timed mode are made from the less vigilant timing threshold to a more vigilant threshold at or near a timing of normal expected breathing of the patient. Such adjustments may be made from a minimum to a maximum vigilance timing settings or incrementally there between as a function of time in the timed mode which is preferably the number of delivered machine breaths.Type: GrantFiled: March 19, 2015Date of Patent: June 14, 2016Assignee: RedMed LimitedInventor: David John Bassin

Patent number: 9238116Abstract: A cushion for a patient interface includes an outer membrane providing a sealing structure adapted to form a seal with the patient's face in use and an underlying membrane generally spaced away from the outer membrane. The underlying membrane provides a support structure for the outer membrane. The outer membrane and the underlying membrane each have an inner edge which defines an aperture to receive the patient's nose in use. The underlying membrane is segmented along its inner edge.Type: GrantFiled: August 18, 2014Date of Patent: January 19, 2016Assignee: RedMed LimitedInventors: David John Worboys, Susan Robyn Lynch
