A sphygmomanometer cuff has inflatable, different-sized chambers (2,3), each having an air-supply duct (10,11). A selector valve means (14) has a number of manually adjustable valve positions, corresponding in number to the chambers, and has one side connected to the air-supply ducts (10,11) of the chambers and another side connectible to an air pump (17). When the sphygmomanometer cuff is applied in position round an arm (40) or a thigh for measuring the blood pressure, indicating means (31-34) give the user a visual indication ("CHOOSE 12","CHOOSE 15"), which depends on the circumference of the arm or the thigh, for manually adjusting the selector valve means (14) to a valve position permitting selective inflation of a chamber of suitable size in view of the circumference of the arm or the thigh at issue. <IMAGE> |
