Patent abstract
The present invention provides a heat and moisture exchange (HME) unit that includes a housing having a fibrous media in the housing that is designed to absorb and retain moisture and heat from exhaled air passing through the housing. The HME unit is designed to transfer the moisture and heat to inhaled air passing through the HME unit. The HME unit has an internal bypass in the housing to enable air to pass through the heat HME unit without passing through the fibrous media. The present invention also provides a breathing circuit that includes a medication bypass HME unit, a medication treatment device and a ventilator that is connected in a closed system.
