Patent number: 10549063Abstract: A flow cassette has a housing with an inlet and an outlet and a passage therebetween. The flow cassette also has a temperature sensor disposed within the passage and configured to measure the temperature of a fluid flowing through the passage, a flow rate sensor disposed within the passage and configured to measure a flow rate of the fluid flowing through the passage, and a processor coupled to the temperature sensor and flow rate sensor. The processor is configured to accept measurements of temperature and flow rate from the temperature sensor and flow rate sensor, respectively, and provide a compensated flow rate.Type: GrantFiled: July 17, 2017Date of Patent: February 4, 2020Assignee: Vyaire Medical Capital LLCInventors: Adrian D. Desilva, Huy Thanh Vu, Richard Le, Jeffrey Harold Miller, Hector Gonzalez, Raul Valdez, Chiun Wang

Patent number: 10539444Abstract: A flow sensor comprises a flow restriction disposed within a passage such that a fluid passing through the passage must pass through the flow restriction. The flow sensor also has an upstream pressure sensor coupled to the passage at a point upstream of the flow restriction and configured to measure and provide an upstream pressure of the fluid within the passage, a downstream pressure sensor coupled to the passage at a point downstream of the flow restriction and configured to measure and provide a downstream pressure of the fluid within the passage, and a temperature sensor coupled to the passage and configured to measure and provide a temperature of the fluid within the passage. The flow sensor also includes a flow sensor processor coupled to the upstream and downstream pressure sensors and the temperature sensor and configured to accept measurements therefrom and calculate a compensated flow rate based at least in part on the measured pressures and temperature.Type: GrantFiled: August 25, 2017Date of Patent: January 21, 2020Assignee: Vyaire Medical Capital LLCInventors: Adrian D.

Patent number: 9962514Abstract: Described herein is a flow control valve for a ventilator that controls gas flow through a patient line in response to a target pressure within the line. The valve controls gas flow by (i) providing both a high frequency signal and a low frequency signal through a coil positioned in a fixed magnetic field, (ii) determining a position of the coil by detecting the high frequency signal, and (iii) controlling a position of the coil by adjusting the low frequency signal based on the determined position and/or velocity of the coil.Type: GrantFiled: June 27, 2014Date of Patent: May 8, 2018Assignee: VYAIRE MEDICAL CAPITAL LLCInventors: Malcolm R. Williams, Adrian D. DeSilva, Huy Thanh Vu
