摘要：
PURPOSE: A respiratory air flow sensor for the hospital pre-phase Cardiopulmonary Resuscitation is provided to enable an accurate air current measurement by using a pitot tube applied principle which converts the kinetic energy of fluid into the dynamic pressure.CONSTITUTION: The two pitot tubes are perpendicularly positioned in the air current direction. A sensing load is mounted on a front of a part in which a respiratory air flow sensor and an oxygen unit are connected. The sensing load forms three holes. In a left side of the sensing load, a tap for measuring the pressure inside the institution is mounted. A chamber in which the diameter is three to four time bigger than the diameter of the airflow path is positioned in a part which is connected with the tube inside the institution. A mesh is installed in the chamber.COPYRIGHT KIPO 2013본 발명은 기체유량센서에 관한 것으로서, 기류의 운동에너지를 동압력으로 변환하여 기류를 측정하는 속도형 변환기(Velocity-type transducer) 형태에 병원전 단계에서 중환자들이 수시로 배출할 수 있는 이물질로부터 센서 소자를 보호할 수 있도록 구조를 보완하여 새로운 형태의 호흡기류센서를 제공한다.
