    Abstract: PROBLEM TO BE SOLVED: To prevent a decrease of a sectional area of a detector. SOLUTION: In a measurement detector D, and particularly in an apparatus for measuring a pressure and/or flow rate of a respiration gas of a patient, a medication is applied to a surface of a wall 2 of a flow path 1 in direct touch with a flow of the gas to be measured and/or a surface of a limiting element 3 so as to decrease a contact angle of the surface and a water drop or a liquid drop including water to be smaller than that without the medication.

    Abstract: Measuring detector and system for the measurement of gas flow, especially for the measurement of the pressure and/or flow of a patient's respiratory gas. The surface of the wall (2) of a flow channel (1) and/or the surface of a restricting element (3), said surface being in direct contact with the gas flow to be measured, is provided with an agent for reducing the contact angle (&thetas;) of a water drop or a drop containing water to said surface in relation to the contact angle formed between a corresponding water drop and a corresponding surface not treated with such agent.

    Abstract: The application relates to an infrared radiation source for a gas analyzer and a method for generating infrared radiation. The infrared radiation source comprises a body (6), thermal insulation material (5) adapted inside the body (6), a radiant element (1) fitted inside the insulation material (5), elements (2, 3) for feeding electric energy to said radiant element (1), and a channel (7) formed in said body (6) and said thermal insulation material (5) in order to pass the radiation generated by said radiant element (1) to the gas under measurement. According to the description, at least the thermal insulation material (5) adapted in close proximity to the radiant element (1) has a low thermal conductivity and the emissivity of the radiant surface (11) adapted in close proximity to the radiant element (1) is greater than 0.5 at the operating temperature of the source.
