    • An HME (heat and moisture exchanger) (10) having a septum (or 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 passages (150b) through which only the inhaled gas (F1) flows, and a second set of passages (150c) through which only the exhaled gas (F2) flows.
    • 具有隔膜(或过滤器)(15)的HME(热和湿气交换器)(10),其通过打褶能够保持和释放热量和湿气的材料的片材(150)而形成。 HME(10)的特征在于隔膜(或过滤器)(15)的壁(15a,15b,15c)部分或全部用密封材料涂覆以限定至少两个暴露区域(A 1,A 2)吸入气体(F 1)和呼出气体(F 2)分别通过其流动。 此外,每个片材(150)在使用中被分成相同的单元(150a),一个在另一个之上,以形成第一组通道(150b),通过该通道仅吸入的气体 F 1)流动的第二组通道和仅呼出气体(F 2)流过的第二组通道(150c)。
