Patent number: 10255647Abstract: Disclosed are methods, systems, apparatus, and products, including a method for operating a respiratory care device that includes collecting at a respiratory care device data representative of operation of the respiratory care device, and communicating to a computing-based device external to the respiratory care device at least some of the collected data to control the operability of the respiratory care device. In some embodiments, the method may further include communicating to the respiratory care device data to controllably change one or more operation parameters of the respiratory care device to cause a change in the operation of the respiratory care device, changing the operation parameters of the respiratory care device according to the communicated data, and communicating to the external computing-based device resultant data representative of operation of the respiratory care device resulting from the controllable change to the one or more operation parameters.Type: GrantFiled: September 28, 2010Date of Patent: April 9, 2019Assignee: Caire Inc.Inventors: Terrell Lee Rodman, Ningda Andy Dai, Patrick T. Bird, Paul L. Edwards, Ronald F. Richard, Peter Armstrong

Publication number: 20100313898Abstract: This disclosure relates generally to a method and an apparatus for delivering a gas to a subject in need thereof, for instance, for the treatment of an unhealthy condition, such as sleep apnea. The method may include sensing the onset of a subject's inhalation and delivering a gas, such as a pulse of gas, in response to the subject's inhalation. For instance, the method may include providing the subject with a gas delivery device configured for delivering a quantity of gas to the subject, such as in response to the subject's need, and instructing the subject to use the device. The device may include a mechanism for generating and delivering the quantity of gas to the subject, as well as a sensor for sensing the subject's need for the gas. A controller for controlling the delivery of the gas to the subject in response to the subject's sensed need for the gas may also be included. The device may further include a cannula to facilitate delivery of the gas to the subject.Type: ApplicationFiled: May 14, 2010Publication date: December 16, 2010Inventors: Ronald F. Richard, Paul L. Edwards, Patrick Dunne, Adrian Knight

Publication number: 20100116270Abstract: A medical ventilator system that allows the use of pulse flow of oxygen to gain higher FIO2 values and/or conserve oxygen is described. In one embodiment, the ventilator system includes an oxygen concentrator, a medical ventilator and a breathing circuit between the ventilator and a patient. In one embodiment, the oxygen concentrator includes a controller module that is configured to generate a trigger signal to initiate the distribution of one or more pulses of oxygen from the oxygen concentrator to the patient circuit at the onset of a ventilator supplied breath. A small flow of oxygen can be added in between pulses to aid in gaining higher FIO2.Type: ApplicationFiled: November 9, 2009Publication date: May 13, 2010Inventors: Paul L. Edwards, Peter S. Armstrong, Richard D. Branson
