Abstract: A sphygmomanometer comprises pressure detection elements for measuring an applied sphygmomanometeric pressure and providing an output indicative of the pressure, and a voice synthesizer responsive to the pressure detection elements for synthesizing voice indicative of the pressure and generating the voice.

Abstract: A carbon rod assembly is disclosed which includes a first carbon rod piece having a projection at one end thereof and a second carbon rod piece having a socket hole at one end thereof. External and internal screw threads of 1/2 to 3 turns are formed on the projection and socket hole respectively, so that the first and second carbon rod pieces are firmly connected by inserting the projection into the socket hole and thereafter rotating the carbon rod pieces relative to each other.

Abstract: A sphygmomanometer is characterized in that, upon completing the blood pressure measuring operation, it automatically informs the operator of the measured values including the systolic and diastolic pressure values stored in a memory circuit by means of synthesized speech. A repeat instruction device prompts repetition of the measured values by synthesized speech, and, when the blood pressure measuring operation is begun, it inhibits the input of the repeat signal so that repeating of verbal information of the measured value is inhibited during a period from the start of pressurizing of the measuring cuff at least until the blood pressure measuring operation is completed.
