A respiratory air humidifier comprises a housing having a flow passage therethrough for the flow of respirator air with a respirator air inlet at one end of the flow passage and a respirator air outlet at the other end of the passage. A plurality of U-shape tubules are disposed in the flow passage and they have walls made of a material permeable to water vapor but impermeable to water. A tubule holder plate closes the flow passage and it is provided with a plurality of bores therethrough of a number corresponding to the tubules located at two spaced locations and into which extend the respective ends of the tubules which are sealed at these ends to the tubular holder plate. A water inlet conduit extends into the inlet of the flow passage and connects the respective inlet end of the tubules, and a water discharge conduit extends out of the flow passage inlet for the discharge of the water from the outlet end of the tubules. The construction includes respective air flow conduits connected through the holder plate and having perforations or air openings along their length which are directed over the surfaces of the tubules so as to pickup the water vapor which advances through the tubular walls in order to humidify the respiratory air.

A respirator air humidifier, comprising a housing having a flow passage therethrough for the flow of respirator air with a respirator air inlet at one end of said flow passage and a respirator air outlet at the other end of said flow passage, a plurality of U-shaped tubules disposed in said flow passage having walls made of a material permeable to water vapor but impermeable to water, a tubule-holder plate closing said flow passage and having a plurality of bores therethrough of a number corresponding to said tubules located at two spaced apart locations, said tubules having respective inlet and outlet ends extending into respective bores at respective locations of said holder plate and being sealed to said plate, water inlet and outlet conduit means extending into said flow passage and connecting the respective inlet and outlet ends of said tubules for circulating water therethrough, and air inlet and outlet conduit means extending through said tubular holder plate for circulating the respiratory air from the inlet of said flow passage over the surfaces of said tubules between said respiratory air inlet and said respiratory air outlet so as to pick off water vapor passed through said tubules to humidify said respiratory air.
