  • Patent number: 11602608
    Abstract: 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.

  • Patent number: 11571524
    Abstract: A system for respiration-controlled application of aerosol in powder form during artificial respiration or assisted respiration of a patient including an interface contacting the patient's respiratory tract, a unit for generating a respiratory gas flow, at least one inspiration line through gas flow is conducted to the interface, an aerosol generator, at least one aerosol line through which the generated aerosol is conducted from the aerosol generator to the interface, and a respiration sensor that detects the patient's respiration signal. A valve in the at least one aerosol line is controlled based on the detected respiratory signal. An intermediate store for generated aerosol in powder form is arranged between the valve and the aerosol generator. The gas flow has a first pressure that is higher than or equal to ambient pressure and the aerosol has a second pressure that is higher than or equal to the first pressure.

  • Patent number: 9765292
    Abstract: A bioreactor for preferably three-dimensional cell culturing comprises a scaffold chamber, a first tube, a second tube and a first valve with a scaffold adapter, a tube adapter and a medium adapter. The first valve has a housing with a longitudinal female portion ending in an opening and a longitudinal actuator being arranged through the opening of the female portion of the housing such that the actuator is arranged partially inside the housing and partially outside the housing, wherein the actuator of the first valve is axially moveable relative to the housing of the first valve between a first position in which the first valve is in the operation position and a second position in which the first valve is in the medium change position. By providing the actuators in the first valve which is applied by axial movements, operation of the bioreactor can be comparably simple and safe.
