Abstract

1479773 Gas humidifiers DRAGERWERK AG 15 July 1974 [14 July 1973] 31321/74 Heading AST An apparatus for humidifying respiration gas comprises a housing 1 defining a gasduct for inhalation gas and exhalation gas, an evaporating device 2 for supplying water vapour to the respiration gas including an electric heating element 3 and a water supply conduit 4 open to said gas duct, a water collecting device 11 disposed below said housing, and a surplus water outlet 12 communicating the interior of housing 1 with said device 11. The housing 1 has a connector 9 for connection to a respirator which provides inhalation gas, a connector 10 for passing inhalation gas to, and exhalation gas from, the patient, and a connector 9a for discharging exhalation gas. The evaporation device 2 has insulated walls. The water collecting device 11 may be formed with a water outlet 16 and/or with overflow apertures 15. The outlet 12 may comprise a nozzle, upstream of which is a dirt filter 13. In a modification, Fig. 2 (not shown), the outlet is defined by a neck projecting upwardly from the bottom of housing 1 and controlled by a float valve. The flow of water from the water supply 6 may be controlled by a regulating valve (not shown).
