Device for increasing the humidification of the air stream breathed by a patient

摘要

A device for increasing the humidification of the air stream breathed by a patient, having a tubular body (2) that can be coupled to a heat and moisture exchange filter (3) and forms a channel (10) for the passage of an air stream. At least one portion of the channel (10) is provided by a membrane (11) impermeable to gases and permeable to ions and molecules with a partial charge. The membrane (11) delimits an interspace (15) that is external to the channel (10) and allows passage of a water vapor flow.
