<p>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. <IMAGE></p> |
