And a cuff spring 3 having a curved shape matching at least a half circumference of the wrist pulsation portion and having the air bag disposed on the inner peripheral side, and an air bag. It comprises a connector 4 built in the cuff band 2 to connect the sphygmomanometer body 1 in communication.
[0011]
The sphygmomanometer main body 10 is mounted at a certain angle α on a mounting base portion 31 a provided on the palm side of the curved plate 31 of the cuff spring 3. That is, the sphygmomanometer body 1 is attached to the mounting base portion 31a with a predetermined angle α (= about 3 degrees) with respect to the axis L of the cuff spring 3 so that the front side B is lifted from the front side A. Has been. And by mounting in this way, the air bag of the cuff belt 2 and the supply / exhaust conduit of the sphygmomanometer body 1 are connected by the connector 4.
[0012]
The outer case 10 of the sphygmomanometer body 1 is composed of an upper case 10a and a lower case 10b, which are combined to accommodate main functional parts for blood pressure measurement. The display unit 11 is provided on the upper surface of the upper case 10a, and the vertical relationship is set so that an appropriate display is obtained when viewed from the front side A. The contents to be displayed include the maximum blood pressure, the minimum blood pressure, and the pulse that are the measurement results. These are displayed digitally.
[0013]
FIG. 2 shows the appearance of the sphygmomanometer body 1. As shown in FIG. 2A, the display unit 11 is arranged close to the front side B of the case 10, the switches 12 are arranged on the front side thereof, and the battery case 13 is arranged on the side unit. As shown in FIG. 2B, the lower surface of the case 10 has a concave curved surface 15 that matches the curved shape of the mounting base portion 31a of the cuff spring 3, and is attached in close contact with the mounting base portion 31a. ing. This serves to prevent the sphygmomanometer body 1 from floating and becoming unstable when the sphygmomanometer body 1 is attached to the mounting base portion 31a at an angle as described above.
