An x-ray diagnostic instrument for taking an X-ray photograph of a patient includes a condition detecting device for detecting a condition of the instrument; a display device for displaying light in multicolor or flushing light; a memory device for storing predetermined display mode data of the display device for each condition of the instrument; and a control device for controlling the display device based on the display mode data stored in the memory device corresponding to a result from the condition detecting device.

An X-ray device includes a cart, a pole vertically provided on the cart, and a telescopic-type extendable supporting arm. The extendable supporting arm is formed of a hollow first arm with one end attached to the pole, a hollow second arm inserted in the first arm to be horizontally movable therein, and a third arm inserted in the second arm to be horizontally movable therein. Also, an X-ray tube device is provided on one end of the third arm. The extendable supporting arm has a synchronous moving mechanism for horizontally moving the third arm according to a horizontal movement of the second arm, and an extension/contraction operating handle attached to the second arm.

An electronic blood pressure meter determines, in an inflation process, pressure Ps correlated to systolic pressure, pressure Pd correlated to diastolic pressure and pulse wave period Pc, and then calculates deflation rate def&minus;v in a deflation process based on a first formula (def&minus;v&equals;(Ps&minus;Pd&minus;mb1)&times;Pc/N, where N represents the number of required beats). Further, maximum inflation value Inf&minus;max is calculated based on a second formula (Inf&minus;max&equals;def&minus;v&middot;(np&times;Pc&plus;&agr;)&plus;Ps&plus;&bgr;1). The pressure is increased to reach the calculated maximum value and then deflation is started at the calculated deflation rate . The blood pressure meter can thus perform a precise measurement in a shortest time.

A sphygmomanometer includes a body and a cuff which is integrally attached to the body and wrapped around the wrist. The body is attached to the cuff such that the body is located on the thumb side of the arm L when the sphygmomanometer is fitted on the wrist. Consequently, a precise blood pressure measurement and precise blood pressure fluctuation can be obtained without restriction on the location where the blood pressure measurement is conducted.
