<p>This disclosure relates to a heat-moisture exchanger (10) comprising first and second parts which are secured together to form a hollow housing (16,17). Ports (18,19) are formed in the housing for connection to a patient and to a source of breathable gas, and the hollow interior of the housing (16,17) forms a passageway for inhalation and exhalation gases to and from the patient. An insert (20) is mounted within the housing (16,17) and across the passageway, and comprises first (31) and second (32) materials. The first material forms a large surface area for the exchange of heat and moisture by condensation and evaporation. The second material is hydrophilic and absorbs moisture and then releases it by evaporation. The insert (20) further acts as a filter of bacteria and virus.</p> |
