Abstract: The invention relates to a multifunctional applicator 6 for mobile use having an applicator plug 7, a supply tube 8, a Y-piece 9, fork tubes 10 and a nose piece 11 with prongs 12, wherein the applicator plug 7 comprises a pressure chamber 21 that has a humidifier interface 17 for connection with a high flow therapy device 1, an oxygen supply port 13 having an opening diameter of at least 1 mm, and a therapy air supply port 14 for the supply tube 8, the humidifier interface 17 and the oxygen supply port 13 within the pressure chamber 21 are both in fluid communication with an upper and a lower valve seat 23, 25 that are provided with a seal 22 and a valve body 24 being movable between said valve seats 23, 25 and said valve body 24 being subjected to a force by a helical compression spring 26 from the direction of the oxygen supply port 13 and on the other hand being pushed against the upper valve seat 25 by an actuating element 28 of the high flow therapy device 1 when the applicator plug 7 is locked in place

Abstract: The invention relates to a small, low-noise side channel compressor for producing a defined volumetric flow, such as is needed in particular for devices for ventilation therapy. This is achieved by means of a new type of shape of the blade chambers (24) in the impeller (12) and the blade chamber walls (29), which separate the blade chambers and become thicker toward the circumference of the impeller, supported by a high-speed drive and a large number of blade chambers (24) at a small impeller diameter.

Abstract: The invention at hand relates to a tracheal applicator for enabling administering high flow therapy to tracheotomy patients, as is known from transnasal insufflation by means of TNI devices and has proven successful. This is attained by an optimized physical simulation of the conditions as available when performing transnasal high flow therapy at the nostril with an inserted prong. The flow of inspiration and expiration flowing through the tracheal applicator is conducted nearly free of turbulences and vortexes owing to further constructive measures while simultaneously preserving an open ventilation system.

Abstract: The invention relates to an applicator for a nasal cannula, comprising a body (11) enclosing a hollow space (22). The applicator further comprises tube connections (20, 21) for supplying a respirable gas into the hollow space (22). The applicator further comprises prongs (18, 19) for administering the respirable gas into the nostrils of a person. A valve (15, 16, 17, 38, 42) is located in a wall of the body (11) so that respirable gas can flow from the outside through the valve into the hollow space (22), but not in the reverse direction. The invention further relates to an applicator having a top of sealing cones (23, 24), wherein the sealing cones (23, 24) may be provided with rim-shaped sealing lips on their side facing away from the body (11), which produce a tight seal with the inner wall of the respective nostril.
