Abstract

1461291 Respiratory gas conditioner KOMBINAT MEDIZINUND LABORTECHNIK LEIPZIG VEB 3 April 1974 [3 April 1973] 14830/74 Heading A5T In a respiratory appliance for warming and humidifying respiratory air, comprising a casing 8 having an inlet 7 and an outlet 5, an evaporation body 2 in the casing, a heat source 1 located within the evaporation body 2, a sensor responsive to the temperature of the air at a patient connector connected to the outlet 5, for controlling the heating of the evaporation body and means for supplying a liquid to the external surface of the evaporation body, the external surface has one or more helical grooves and part of the external surface bears sealingly against the internal surface of the casing. The liquid which is fed through 6 by a dosing pump (15, Fig. 2 not shown) flows over the hot evaporation body and as a result, the respiratory air stream flowing from 7 to 5 is humidified and warmed. A device (16) along with a temperature sensor (18), the latter measuring the temperature of the air near the patient, controls the temperature of the evaporation body. The liquid collected at the bottom of the casing is recycled through the dosing pump (16). The evaporation body is made of a liquid-absorbent flexible or elastic material or is coated with such a material.
