Patent number: 11602608Abstract: A method and device are used for administering a humidified aerosol to a patient interface by providing and guiding a first gas flow having a humidified aerosol, a second gas flow having humidified respiratory gases, and a liquid flow of a thermally balancing liquid, thermally balancing the first and second gas flow by parallel guiding the first and second gas flow such that the first and second gas flow are guided in a manner that they are at least partially surrounded by the liquid flow of the thermally balancing liquid, mixing the first and second gas flow to obtain enriched respiratory gases having the humidified aerosol, and administering the enriched respiratory gases to the patient interface. The method and the device avoid the administration of dry or re-dried powdered aerosols and unwanted accumulation of and blockage by powdered material. The device is useful in respiratory support of preterm infants.Type: GrantFiled: September 17, 2018Date of Patent: March 14, 2023Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FÖRDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Gerhard Pohlmann, Peter Iwatschenko, Jelena Pankalla
