Abstract: In a sphygmomanometer of the present invention, a cuff is attached to a rotating shaft on a rear surface side opposite to a front surface side arranged facing a subject during blood pressure measurement. A swing mechanism maintains a tilt angle of a central axis of the cuff with respect to a horizontal plane at a certain standby angle in a standby state of an upper arm not being inserted into the cuff, and also allows the tilt angle of the cuff to become either larger or smaller than the standby angle by the upper arm being inserted into the cuff.

Abstract: A pair of heat exchangers of generally cylindrical shape are coaxially coupled to the opposite ends of a cylindrical air-water separator. Each heat exchanger has a stack of heat transfer disks brazed together to define two alternating sets of intercommunicating flow paths. The first set of flow paths of the first heat exchanger receives high-temperature, high-humidity air under pressure, which is precooled by low-temperature, low-humidity air flowing to the second set of flow paths from the air-water separator. The precooled high-humidity air is directed through an internal passageway in the separator into the second heat exchanger, in which the air is cooled by heat exchange with a coolant. The cooled high-humidity air is then directed into the separator for reduction of the moisture. The low-temperature, low-humidity air is then afterheated by precooling the incoming high-temperature, high-humidity air in the first heat exchanger, for subsequent delivery to a load.
