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 present invention relates to a method of compensating the pressure drop in an ordinary ventilator tube. The method comprises the measurement of a first air flow at a first pressure on the apparatus' side of the ventilator tube and with the respiratory mask taken off. Moreover, a parameter is calculated in a function which provides the pressure drop in the ventilator tube in dependence on the air flow. The parameter for the air flow and pressure is calculated. Later, the air flow is calculated with the respiratory mask being put on. By means of the function a correction pressure is calculated from the air flow. Finally, a target pressure is set which results as a sum of the selected mask pressure and the correction pressure. The invention moreover relates to ventilator for performing the aforementioned method and to a memory medium for storing a corresponding program.
