A motor, a pump, a rapid evacuation means, a constant speed evacuation means, a battery, a pressure sensor, a control circuit section, etc., which are required for blood pressure measurement, are housed and arranged in the main body case 1, and the lower surface is in a flat state. Thus, by making the lower surface part flat in this way, the main body case 1 is made thin.

The cuff band 2 is mainly constituted by a clip plate 3 and a blood bag 6 inside the cuff band main body 2a, and the engaging hooks 4 extend from the clip plate 3 toward the outside of the cuff band main body 2a.
Is projected. As shown in FIG. 1, the arrangement state of the clip plate 3 and the blood vessel bag 6 in the cuff band 2 is such that the clip plate 3 is arranged on the upper side of the blood vessel bag 6 and covers the blood vessel bag 6 and the clip plate 3. The cuff band body 2a is arranged. When the cuff band 2 is attached to a body blood pressure measurement site such as the upper arm, wrist or arm, the cuff band body 2a, the blood flow blocking bag 6 and the clip plate 3 fit well along the human blood pressure measurement site having a substantially circular cross section. It is formed in an arc shape so that it can be mounted.

Engaging hook 4 projecting from clip plate 3
Are a pair of protrusions from the outer surface of the upper portion of the clip plate 3,
Retaining protrusions 4a are respectively provided on the upper portions so as to project outward. A pair of through holes 7 are formed in the bottom plate of the body case 1 so as to be adjacent to each other. The engaging hooks 4 are inserted into the through holes 7 to prevent the engaging hooks 4 from coming off.
By engaging with the opening edge of the through hole 7, the engaging hook 4
The cuff band 2 is attached to the lower part of the main body case 1 via.

A protrusion 5 for preventing the engagement hook 4 from coming off is provided on the outside of the engagement portion a between the main body case 1 and the cuff band 2 which are formed by inserting and connecting the engagement hook 4 into the through hole 7. Has been. 1 to 3, a protrusion 5 is provided on the upper surface of the outer end portion of the clip plate 3 outside the engaging portion a between the main body case 1 and the cuff band 2.

Even if the protrusions 5 are provided so as to be continuous along the longitudinal direction at both ends of the clip plate 3 as shown in FIG. 3 (a), they are arranged at predetermined intervals as shown in FIG. 3 (b). A plurality of them may be provided separately from each other. Further, even if the protrusion 5 is made of the same material as the clip plate 3 and integrally protrudes from the outer surface of the clip plate 3, a separate member such as rubber is attached afterwards to the clip plate 3.
Either of them may be attached to the outer surface of the.

When the blood pressure is measured by mounting the cuff band 2 on the body blood pressure measurement site, when the blood vessel bag 6 in the cuff band 2 is inflated, both ends of the clip plate 3 are indicated by arrows B in FIG. However, the protrusion 5 abuts the lower surface of the main body case 1 via the cuff band main body 2a to prevent the clip plate 3 from spreading, and the engagement hook 4 of the clip plate 3 is inserted from the through hole 7. It prevents you from getting out. That is, when the lower surface of the main body case 1 is made flat in order to reduce the thickness dimension of the main body case 1, when the blood vessel bag 6 swells and the end portion of the clip plate 3 is widened, it is projected from the clip plate 3. The engaging hook 4 moves in the outward direction as shown by the arrow C in FIG. 2 along with the spread of the clip plate 3, the blood vessel bag 6 swells, and the end of the clip plate 3 is flat along the lower surface of the main body case 1. If it spreads until it hits in such a state, the retaining hook 4a locked to the opening edge of the through hole 7 will be disengaged from the opening edge, and the engaging hook 4 will slip out of the through hole 7. When the protrusion 5 hits the lower surface of the main body case 1 via the cuff band main body 2a as described above, the bending of the clip plate 3 is limited, and the engagement that may occur when the clip plate 3 bends The hook 4 comes off It is that there is no that you can. Therefore, even if the thickness of the main body case 1 is reduced by making the lower surface of the main body case 1 flat, the cuff band 2 and the main body case 1 are connected and assembled by using the engaging hooks 4 provided on the clip plate 3. However, the connection by the engagement hook 4 cannot be easily released, and the main body case 1 is made thin while the connection between the main body case 1 and the cuff band 2 is made reliable, thereby improving portability. It can be done.

FIG. 4 and FIG. 5 show another example, in which both ends of the lower surface of the body case 1 are projected as the outside of the engaging portion a between the body case 1 and the cuff band 2. A section 5 is provided. 5B, even if the protrusion 5 is provided continuously at both ends of the lower surface of the main body case 1 along the longitudinal direction as shown in FIG. 5A, as shown in FIG. 5B. A plurality of them may be provided in a state of being separated by a predetermined interval, and any of them may be provided. Also,
The protrusion 5 is made of the same material as the lower surface of the body case 1, and the body case 1
It does not matter whether it is provided so as to integrally project from the lower surface of the main body 1 or it may be attached to the lower surface of the main body case 1 by a separate member such as rubber afterwards.

Also in this case, even if the thickness of the main body case 1 is reduced by making the lower surface of the main body case 1 flat, the linking assembly of the cuff band 2 and the main body case 1 is provided on the clip plate 3. Although it can be easily performed by using the combined hook 4, the connection by the engagement hook 4 cannot be easily released, and the main body case 1 is made thin while ensuring the connection between the main body case 1 and the cuff band 2. It is possible to improve portability.

[0015]

According to the first aspect of the present invention, the engaging hook projecting from the clip plate in the cuff band is connected and fixed to the lower portion of the main body case, and is engaged outside the engaging portion between the main body case and the cuff band. Since the protrusions are provided to prevent the engagement hooks from coming off, the engagement hooks can be prevented from coming off by the protrusions even if the lower surface of the main body case is not formed in a shape along the outer peripheral shape of the cuff band. Therefore, the main body case can be made thinner, and the main body case and the cuff band can be prevented from coming off without deteriorating the portability.
