It is composed of a coaxial cylindrical finger insertion guide and a cuff holder that is placed between the opposing finger insertion guides and holds the cuff in a wound state.A pressure sensor and a pressure pump are arranged side by side on the battery box. And further On the force sensor and the pressure pump, in which to arrange fixing the printed circuit board.

According to a second aspect, in the electronic blood pressure monitor for a finger according to the first aspect, air tubes extending from the pressure sensor and the air pump are connected between the battery box and the cuff holder, and a base of the cuff is connected. Then, an air socket for holding the cuff at a predetermined position in the cuff holder is fixed to the bottom surface of the case and provided in an upright state.

[0007]

[Function] Since the outer shape of the sphygmomanometer main body is a roughly egg-shaped with a palm-sized, and the finger insertion hole is provided inside the main body case, the sphygmomanometer main body is not angular, and when held in a hand or in a pocket. No discomfort when stored in. A battery box was formed on the bottom surface of the lower case of the main body of the sphygmomanometer in the longitudinal direction, and a relatively heavy air pump and pressure sensor were placed in parallel on the battery box. It is located on the bottom side of the central part in the direction, and has good stability when the sphygmomanometer body is placed and good balance when held in the hand.

Further, since the air pump and the pressure sensor having substantially the same thickness are arranged in parallel on the battery box having a predetermined planar space, and the thin printed circuit board is further arranged on the air pump, the parts are provided in the main body case. Efficiently, and the space for accommodating other parts arranged in the main body case becomes wider.
