Abstract: A toilet-installed digital sphygmomanometer provided with retractable cuffs. A housing (36) is arranged laterally of a toilet seat and two occluding finger cuffs (62) different in size are mounted to associated respective sliders (70) in a manner movable relative to the housing (36). In use, one of the sliders is moved to permit a cuff (62), of a size suited to the size of the user's finger, to protrude out of the surface of the housing (36) for engagement by the finger. When not in use, all the cuffs are retracted within the housing so that the cuffs are kept clean. In another embodiment, a plurality of pivoting arms are hinged to the housing and the cuffs different in size are mounted, respectively, to the associated pivoting arms. In still another embodiment, a plurality of cuffs different in size are mounted to a revolving member journaled to the housing and a particular cuff is selected by rotating the revolving member.
