Abstract

1,186,984. Anaesthetising apparatus. O. H. DRAGER [trading as DRAGERWERK, HEINR. & BERNH. DRAGER]. 27 June, 1968, No. 30750/68. Heading A5T. An evaporator for evaporating liquid anaesthetic has an evaporating surface of a waterrepelling porous plastics. Preferably the evaporator has separate evaporating and supply chambers (for the anaesthetic), and also has a water repelling porous plastics element which provides the evaporating surface in the evaporating chamber and also extends from the supply chamber to the evaporating chamber to convey the liquid anaesthetic by capillary action to the evaporating chamber. This embodiment is illustrated in the Figure, wherein the anaesthetic is conveyed from supply chamber 3 by capillary action up the waterrepelling porous plastic wick 5 into the evaporating chamber 4 which is lined with the water repelling porous plastic material 6 as an additional evaporating surface. The screw thread 2 connects to the lower portion of an anaesthetising apparatus, and the internally threaded piece 1 screws into a meter for measuring the anaesthetic content of the breathing gas. This arrangement of connecting pieces is such that the evaporator cannot be used in the apparatus unless the meter is connected into the breathing circuit. The valve 7 controls this gas flow.
