[Means for solving the problem]

In order to solve the above-described problems, the present invention provides a main body and a band with a sensor provided with a pulse wave detection sensor as separate bodies.
Further, the material of the band with the sensor is made elastic so that the mounting state is stabilized.

[Action]

In the arm-measurement type pulse wave measuring device configured as described above, the band with the sensor completely follows the wrist including the radius, and the wearing state is stabilized, so that the sensor detection sensitivity can be improved. Was.

Further, by separating the main body and the band with the sensor, the relative positions of the main body and the band with the sensor at the time of mounting become free.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the pulse wave measuring device of the present invention.
The sensor 12 is attached to the sensor band 14 and the connection cord
It is connected to the main body 11 by 15. The connection cord 15 may be connected to the main body 11 and the sensor band 14 with a connector so as to be detachable. In the body 11,
As shown in FIG. 2, a pulse wave calculating means 22 and a display means 23 are built in. The signal transmission means 24 is connected between the sensor 21 and the pulse wave calculation means 22.

The sensor band 14 is made of a stretchable material, for example, a rubber-containing fiber such as a supporter.

The mounting state of the pulse wave measuring device of the present invention will be described with reference to FIG.

 The main body 31 is attached to the wrist by the band 33.

The sensor band 34 is worn so as to hit the upper part of the artery 38 on the side surface of the radial part 35 of the wrist. Sensor band 34
Since is a stretchable material, it completely conforms to the radial portion 35, and no gap is formed between the radial portion 35 and the sensor band 34, so that a stable mounting state is achieved.

FIG. 4 shows one embodiment of attaching the sensor to the sensor band.

In FIG. 4, a lead wire is provided inside the sensor band 43.
44 are installed inside. The connector 41 is a lead terminal
A lead wire 45 and a lead terminal 45 are connected, and then integrally connected to the sensor band 43.

The sensor capsule 42 has a sensor 47 at one end,
The sensor 47 and the capsule electrode 46 are electrically connected inside. The sensor capsule 42 is
It can be inserted and connected, and can be freely removed.

When the sensor capsule 42 is inserted, the capsule electrode 46 and the lead terminal 45 are brought into contact with each other.

 FIG. 5 shows another embodiment of the sensor band.

The sensor band body 51 may be formed of a stretchable material such as a supporter, or may be an expansion band having a stretchable structure. A gel-like resin cover 54 is provided so as to form a bag-like void on the inner surface of the sensor band 51. A gel resin is sealed in a bag-shaped space formed between the sensor band body 51 and the gel resin cover. A seicer 55 is attached to the gel resin cover 54.

〔The invention's effect〕

The present invention, as described above, comprises a sensor band with a sensor, a pulse wave measuring device main body with a band, the sensor band with a sensor, and a connection cord for connecting the pulse wave measuring device main body with a band. Thus, the sensor position of the sensor band with sensor can be freely adjusted to the artery near the radius bone without being restricted by the mounting position of the pulse wave measuring device body with band.

By making the sensor band with the sensor extendable and contractible, there is no gap between the radius part and the band, so that the mounting state is stabilized and the pulse wave detection can be stabilized.

The sensor portion is a capsule configured separately from the band of the band with the sensor, the capsule with the sensor has a structure that can be detached from the band, and the connection cord is connected to the main body with a connector to have a detachable structure. It is possible to attach only the main unit. For example, when the main body is provided with a function such as a clock, there is an effect that the main body alone can be used.

In addition, by forming the sensor portion in a capsule shape separately from the band of the band with the sensor and the capsule with the sensor being detachable from the band, if the sensor mounting band becomes dirty, only the band is washed. There is also an effect that can be done.
