DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the embodiment shown in the drawings. As shown in FIG. 4, the sphygmomanometer of the illustrated example is used by attaching it to a wrist, As shown in FIG. 1, the compression band 2 includes a blood-blocking bag 20 having a length substantially around the wrist, and a circular arc-shaped clip plate 21 surrounding the outer periphery of the blood-blocking bag 20. Surface fasteners 22 and 23 are attached to the outer surface at one end and the inner surface at the other end so as to be freely engageable with each other. The clip plate 21 here has elasticity made of a synthetic resin, and makes it easy to attach the compression band 2 to the wrist.
The inflation of the blood bag 20 to the outer surface side is restricted.

On the other hand, the main body 1 has a battery housing 11 on one side.
A display unit 15 and switches 16 and 17 are disposed on the upper surface of the center, and the circuit boards 13 and 13 and the liquid crystal are disposed in the center. A display plate 14 is provided, and the compression band 2 is provided to project from the outer surface of the
At this time, the pump unit 3 and the blood bag 20 communicate with each other through the nozzle 30 and are provided on the circuit board 13 as shown in FIG. The pressure sensor 18 and the blood bag 20 are communicated through the nozzle 19. In the figure, reference numeral 25 denotes a packing for preventing air leakage from the nozzles 19 and 30.

Here, the battery storage section 1 of the main body 1 is provided.
The pump housing 1 and the pump housing 12 are configured to project obliquely downward from the center of the main body 1 on both sides, respectively, so that the bottom surface of the center of the main body 1 becomes a recess between the housings 11 and 12. When the compression band 2 is connected to the bottom surface, the main body 1 is attached in the circumferential direction to the outer surface of the compression band 2 which is kept in an arc shape by the clip plate 21. For this reason, when the clip plate 21 is bent when the compression band 2 is wound around the wrist, the bending of the clip plate 21 is limited by the main body 1 as shown by a chain line in FIG.
The hook 24, which may occur when the clip plate 21 is largely bent, does not come off. That is, although the connection assembly of the compression band 2 and the main body 1 can be easily performed by using the hook 24, the connection by the hook 24 is not easily released.

In the main body 1, a heavy battery 6 is accommodated in a battery housing portion 11 protruding to one side, and a pump unit 3 similarly heavy is accommodated in a pump housing portion 12 protruding to the other side. Since the center of gravity as a whole is located at the lower center of the main body 1, when the compression band 2 is wound around the wrist, the clip plate 21 is bent with the wrist facing upward and put on the wrist. Time, FIG. 6
As shown in the figure, the center of gravity Pa of the battery 6 and the center of gravity Pb of the pump unit 3 are distributed to the left and right, and a stable state can be maintained.
It is easy to perform the winding operation by engaging the one hand with one hand. Furthermore, the planar fastener 2
Even if the position of the main body 1 is slightly shifted as shown in FIG. Therefore, the center of gravity of the entire main body 1 is also a low center of gravity, so that the main body 1 does not slip off from the wrist.

The sphygmomanometer is set on a desk in view of the relationship between the shape of the main body 1 and the fact that the compression band 2 has an excellent arc shape due to the built-in clip plate 21 and the protection of the display unit 15. As shown in FIG. 8, when placing the main body 1, the center of gravity of the entire main body 1 is set as described above so that a stable state is maintained regardless of which of the main bodies is placed. In addition to being placed at the center in the width direction, it is also located at the center in the orthogonal direction. In order to satisfy this condition, in the illustrated example, the battery 6 is placed on one side of the main body 1 and the other side. The pump unit 3 is arranged in the main body 1
Electronic components are arranged in the upper part of the central part, and air piping is arranged in the lower part. As a result, as shown in FIG. 5, the convenience of assembling the electric system member C with the pneumatic pump unit 3 and piping is also improved.

Further, as shown in FIG. 2, in addition to the motor 31 and the pressurizing pump 32, the pump unit 3 includes a quick exhaust valve 33 and a gradually exhausting valve 34 connected to the pressurizing pump 32 by tubes 35, respectively. The quick exhaust valve 33 is formed as an electromagnetic valve including a yoke 330, a coil bobbin 331, a coil 332, and a plunger 334, as shown in FIG. Is used, the valve portion 336 is closed when suction is performed against the return spring 335. When the moving direction of the plunger 334 for closing the valve portion 336 is M, FIGS. As shown in Fig. 5, when the device is worn on the wrist, this direction M is directed obliquely downward. That is, the direction is such that the plunger 334 compresses the return spring 335 by its own weight. For this reason, the return spring, which is a closing operation of the rapid exhaust valve 33, between the time when the blood pump 20 is pressurized by the pressurizing pump 332 and the time when the blood pressure is measured by gradually exhausting from the exhaust valve 34. In the suction movement of the plunger 334 against the 35, there is no need to oppose the own weight of the plunger 334, and a small amount of current flows through the coil 332, and the life of the battery 6 can be extended.

FIGS. 10 and 11 show another embodiment. The clip plate 21 provided on the compression band 2 has a length that surrounds a little over half of the circumference of the wrist, and the main body 1 is connected to a position near one end of the clip plate 21. When air is sent to the inflatable bag 20 to inflate it, the portion of the blood bag 20 that is not surrounded by the clip plate 21 is expanded more than the region that is surrounded by the clip plate 21. ,
The main body 1 is tilted by the angle θ, and as a result, the display unit 15 of the main body 1 in the sphygmomanometer attached to one hand is easy to see for the subject.

[0014]

In the present invention as described above, according to the present invention, heavy in the body are those that are disposed distributed across along the circumferential direction of the compression zone, upper body has a low center of gravity
