Is disclosed.

[0004]

The arm bands of the sphygmomanometer described in the above-mentioned prior art are all manufactured according to a standard in which the diameter at the time of release of the core is almost constant for ordinary persons. For this reason, it is tight when worn by people with thick arms,
If you are a thin person, you will be in a loose state. Particularly in the case of an extremely thin person, a gap is easily formed between the arm and the arm. When used by such a person, it is necessary to wrap the band-shaped part of the arm band to eliminate the gap, which is difficult to use, and sometimes it is difficult to wrap it alone, and the help of an attendant is required. Sometimes things didn't happen.

[0005] The present invention is devised and even a thin person with arms to be used in the absence of inconvenience as described above
An object of the present invention is to provide an arm band of a new blood pressure meter and facilities to other ideas.

[0006]

In order to achieve the above object, a cuff for a sphygmomanometer according to the present invention is composed of a core main body 1 made of an elastically deformable material such as polypropylene or hard polyvinyl chloride having a curved shape with a superior arc. When a one side edge the same material made of core Fukukarada 2 exhibiting a curved shape of the inferior arc linked as lifting擺動inward and outward through the hinge-like portion 3 to the core body 1, with respect to the core Fukukarada 2 The core is in a state of applying restoring force in the direction of inward tilt
The core 5 composed of the elasticity imparting portion 4 provided on the main body 1 is disposed outside the air bag, or the point 7 corresponding to the measurement point 6 in the core is replaced with the point 6. It is curved in a state of close contact.

[0007]

When a person with a thin arm is used, as shown in FIG. 5, the position is determined by temporarily holding the core sub-body 2 on the thin arm using the pinching force due to the restoring force of the core sub-body 2, and this positioning state is maintained. It forms the wound of the strip-shaped portion 8 in the乍Ra arm band
When the band-shaped portion 8 is wound, there is no gap because the core sub-body 2 is in contact with the arm in advance by the restoring force, and the curved portion 7 is in close contact with the measuring point portion 6. I do.

[0008]

The arm band of the sphygmomanometer according to the present invention can be temporarily held and positioned even on a thin arm by the action of the restoring force of the core sub-body 2 as described in the above operation. In addition, when the band-shaped portion 8 is wound, the core sub-body 2 is restored by the restoring force of the elasticity applying portion 4 and
The restoring force causes the curved portion 7 to be in a state of being in close contact with the arm in advance, and it is not necessary to wind the arm band portion while maintaining the gap as in the above-described conventional example ( There is a little.)
It can be easily wound around a correct position without an attendant, and is much more convenient than the above-mentioned conventional one.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in the drawings, a core body 1 having a prominent arc-shaped curved shape is constituted by polypropylene.
A core sub-body 2 having an inferior arcuate curved shape is provided on one side edge of the core main body 1 via a bendable thin hinge-like portion 3 and is capable of sliding inward and outward. The elastic applying portion 4 is provided by a U-shaped leaf spring 9 for applying a restoring force in a direction of inwardly tilting inward, and a portion 7 corresponding to the measurement point portion 6 in the core main body 1 is provided. The core body 5 is obtained by curving the core body 5 as closely as possible to the point location 6, and this core body 5 is air-bagged (not shown).
And placed in the belt-shaped body 10.

Claims (2)

(57) [Claims] 1. A core body 1 made of an elastically deformable material, such as polypropylene or hard polyvinyl chloride, having a curved shape with an excellent arc, and a free-sliding inward and outward direction via a hinge-like portion 3 on one side edge of the core body 1. a core Fukukarada 2 made the material exhibiting a curved shape of the inferior arc linked as was provided in the core body 1 in a state to impart a restoring force in a direction tilted inward with respect to the core Fukukarada 2 An arm band for a sphygmomanometer, wherein a core body 5 composed of an elasticity applying part 4 is disposed outside an air bag. 2. A wristband for a sphygmomanometer, wherein a point 7 corresponding to a measurement point 6 in a core body is curved so as to be in close contact with the point 6.
