Abstract
Disclosed is an apparatus for measuring respiratory gas flow, which provides a high accuracy in measurement of the respiratory gas flow and reduces the manufacturing cost of the apparatus, in comparison with the conventional disposable apparatus for measuring respiratory gas. The apparatus includes a measurement module and a respiratory tube assembly. The respiratory tube assembly comprise a cylindrical tube body and a sensing rod inserted through the cylindrical tube body. The sensing rod is shaped like the number “1” and has a plurality of sampling pores and two air passages. Locations of the sampling pores are determined by equal area division method in which a circular section of the cylindrical tube body is divided into a plurality of annuluses with equal areas and the sampling pores are formed at the positions also equally dividing the annuluses to which the sampling pores belong.
