DIFFERENTIAL PRESSURE SENSOR FOR RESPIRATORY MONITORING

摘要

A differential pressure sensor (100) for measuring respiratory gas flow including a tubular housing (102) having a bore containing a diametrically-oriented, longitudinally extending strut (104) containing first and second lumens (122, 126) having longitudinally spaced pressure ports (120, 124) at axially spaced locations of the strut (104), the ports (120, 124) being located on opposite sides of a bore restriction.
