Abstract

1,086,806. Respiratory appliances. O. H. DRAGER, [trading as DRAGERWERK, HENR. & BERNH. DRAGER]. March 29, 1965 [March 28, 1964], No. 13312/65. Heading A5T. Apparatus (5) for use in a closed-circuit respiratory appliance comprises a flexible inhalation hose 6, 8 in which is a cooling device in the form of a container 12 for the coolant, the device having a thermally conductive wall portion and the apparatus including a duct 10, 14, 15 serving to lead inhalation gas past, and in contact with, the wall portion. As shown an outer container 11 fits about the container 12 to provide the duct 14 and is also formed with a cap 16 for withdrawing condensate and saliva. An optional duct 7 allows gas to by-pass the device depending on the position of a valve 9 which is controlled manually or by a thermally responsive spring 18. Carbon dioxide snow may be used as the coolant and, as in Figure 1 (not shown), the appliance may also include in a pack (1) a source of breathing gas under pressure, a breathing bag, and a carbon dioxide absorbing cartridge.
