<P>PROBLEM TO BE SOLVED: To provide a medical heat and moisture exchanger. <P>SOLUTION: This medical heat and moisture exchanger (HME) 10 includes a septum (or a filter) 15 formed by pleating a sheet 150 of material capable of retaining and releasing heat and moisture. The HME 10 is characterized in that walls 15a, 15b, 15c of the septum (or filter) 15 are coated partly or completely with sealing material to define at least two exposed areas A1, A2 through which inhaled gas F1 and exhaled gas F2 flow respectively. Moreover, each sheet 150 of material is divided into identical units 150a, fan-folded, in use, one on top of another to form a first set of passages150b through which only the inhaled gas F1 flows, and a second set of passages 150c through which only the exhaled gas F2 flows. <P>COPYRIGHT: (C)2009,JPO&INPIT |
