Abstract: A device is provided for measuring the velocity of flow of a fluid in a respiration system and includes a first thermal sensor element (5) provided with a controllable heating element (50) and a second thermal sensor element (6). The thermal sensor elements (5, 6) are arranged at spaced locations from one another at a path of flow, so that a thermal signal generated by the first sensor element (5) with the heating element (50) is transmitted to the second sensor element (6), and the second sensor element (6) is designed to detect the thermal signal from the fluid flow. The second sensor element (6) is connected to the first sensor element (5) via feedback (12) which triggers another thermal signal. A controlling and analyzing device (13, 15) is connected to the sensor elements (5, 6) to start the generation of a first thermal signal and to read and analyze the signal frequency as an indicator of the velocity of flow.

Abstract: A gas inlet is disposed in a lower portion of a reaction chamber, a copper substrate is disposed in an upper portion thereof, and a tungsten catalytic body heated to 1600° C. is disposed midway between the two. Ammonia gas introduced from the gas inlet is decomposed by the tungsten catalytic body, a chemical species generated by the decomposition reacts with a surface of the copper substrate, and reduces and removes a contaminant on the copper surface, and a Cu3N thin film is formed on the copper substrate surface. This Cu3N film has the action of a film which prevents the oxidation of copper. This Cu3N film is thermally decomposed and removed when heated to temperatures of not less than 300° C., leaving a clean copper surface behind.

A pre-inspiratory inspiratory gas flow is set, which flows off via the expiration valve (9). The closing pressure pv of the expiration valve is measured with a pressure sensor (11) in the process. The gas flow is increased in case of an inspiratory effort of the patient to the extent that the closing pressure pv of the expiration valve (9) is restored. Breath support is generated when the difference between the preset gas flow and the gas flow that is needed to maintain the closing pressure pv at a constant level exceeds a predetermined threshold value.
