Abstract
1,242,694. Humidification of air. FISHER & PAYKEL Ltd. 27 Sept., 1968 [27 Sept., 1967], No. 46082/68. Heading AST. [Also in Divisions B1 and F4] An apparatus for heating and humidifying air for use in respirators comprises heating and humidifying means for heating air to an output temperature not exceeding a maximum desired delivery temperature and for humidifying the air to at least 85% saturation with water vapour at that output temperature, further heating means distributed along the length of a flexible hose which receives the humidified and heated air for heating if further to a temperature above the output temperature, means for conveying the air from the flexible hose including an expiratory valve and means for ensuring that the heated and humidified air is delivered from the apparatus at no more than the said maximum desired delivery temperature. The further heating means prevents cooling of the humidified air with consequent precipitation of water in an unheated expiratory valve and breathing mask of a respiratory apparatus. Preferably the heating and humidifying means comprises a pressurisable and removable water container 31, having a lid 30, sealable water inlet 55, water absorbent material, e.g. filter paper along the spiral passage formed by a spiral heating plate 33, air inlet and outlet passages 52 (Fig. 6, not shown) and 51 at opposite ends of the spiral passage, at least the outlet passage being above water level the absorbent material and spiral plate being partially immersed in water providing a lower seal to the passage, the top of the passage being sealed by the bonding of plate 33 to disc 34 with, as shown, rubber annulus 35 providing a seal to the lid. The spiral plate may have a heating element attached or may, as shown, be the heating means. The water temperature is controlled by thermostat 49; a thermistor 58 controls the temperature of the output all. Stepdown transformer 60 provides output voltages to operate the thermostat, warning lights and flexible hose heater and the input voltage for stepdown transformer 63 which provides the current for treating spiral plate 33.
