摘要： A heat and moisture exchanger (HME) media disk and associated virus and bacteria filter disk are placed in a housing of two clear plastic shells ultrasonically welded together and having ports at opposite ends of the housing for connection of flexible respiratory tubing to them. A guide vane is situated across the port at the patient end of the housing and extends into the HME and provides turbulence for efficient usage of the media for heat and moisture exchange functions. Vanes are provided in the housing adjacent the machine end port of the housing. A carbon dioxide sampling tap is provided on the machine end portion of the housing. The vanes are tapered from a small or narrow edge at the disk surface to thicker cross sections at increasing distances from the disk toward the housing end ports. Provision for connections to standard tubing is made at the ports.
