Patent number: 11497880Abstract: Systems, methods, and devices for humidifying a breathing gas are presented. The system includes a source of pressurized breathing gas, a vapor transfer unit external to the source of pressurized breathing gas, a first gas tube connecting the source of pressurized breathing gas to the gas inlet of the vapor transfer unit and having a first length, a liquid supply having a heater that heats liquid, a first liquid tube coupling the liquid supply to the liquid inlet of the vapor transfer unit, and a second gas tube having a second length and connecting the gas outlet to a patient interface. The first length is greater than the second length. The vapor transfer unit includes a gas passage, a liquid passage, and a membrane separating the gas passage and the liquid passage. The membrane is positioned to transfer vapor from the liquid passage to the gas passage.Type: GrantFiled: July 23, 2019Date of Patent: November 15, 2022Assignee: VAPOTHERM, INC.Inventors: Felino V. Cortez, Jr., Charles Busey, George C. Dungan, II

Patent number: 11364358Abstract: Systems, devices, and methods are disclosed for nasal cannulas allowing simultaneous flow of humidified breathing gas and aerosolized medicament for use in respiratory therapy. Utilizing separate flow paths and separate cannula outlets for the heated and humidified breathing gas and for the aerosolized medicament, these systems, methods, and devices reduce condensation of the aerosolized medicament by delaying mixing of the flow of aerosolized medicament and the flow of heated and humidified breathing gas until the flows exit the cannula.Type: GrantFiled: June 30, 2016Date of Patent: June 21, 2022Assignee: Vapotherm, Inc.Inventors: Felino V. Cortez, Jr., Charles Busey, George C. Dungan, II

Publication number: 20220054791Abstract: Apparatus and methods for delivering a heated and humidified mixture of oxygen and air are provided. The apparatus includes an air compressor and oxygen concentrator enclosed in the housing of a vapor transfer system. The air compressor supplies air at a first pressure to a gas inlet. The oxygen concentrator provides oxygen at a second pressure to the gas inlet. The oxygen concentrator and the air compressor are in fluid communication and are configured such that the first pressure of the compressed air and the second pressure of the oxygen are about equal. The apparatus includes a vapor transfer system having a gas passage, a liquid passage having heated liquid and vapor, and a membrane that separates the gas passage and liquid passage. The membrane is positioned to transfer vapor from the liquid passage to the gas passage.Type: ApplicationFiled: June 29, 2021Publication date: February 24, 2022Inventors: Felino V.
