Description

The present invention relates to a wristband that protects the wrist.

Conventionally, for example, as disclosed in Patent Document 1, a wristwatch has an arm fixing band that can be fixed around the wrist, a wristwatch is arranged on the outer peripheral surface of the arm fixing band, and the wristwatch belt is used as the arm fixing band. There was an additional wristwatch band that could be fixed. This add-on watch band allows the watch to be worn without direct contact with the skin, causing the watch to rub against the skin and feel uncomfortable, or certain materials of the watch to touch the skin for allergies, rashes or rashes. It is possible to prevent symptoms such as eczema from appearing.

In recent years, due to the growing health consciousness, a wristwatch-type health management device having a function of easily measuring the wearer's pulse has been attracting attention. This type of pulse measurement is performed by an optical method that identifies the pulse by irradiating the surface of the wrist with irradiation light, receiving the reflected light reflected from the wrist, and analyzing the change in the amount of irradiation light and the reflected light. Is common. For example, Patent Document 2 discloses a wristwatch-type heart rate detecting device that performs optical pulse measurement.

Since the additive wristwatch band of Patent Document 1 does not consider not to block the irradiation light or the reflected light of the pulse measurement, it cannot be used for a health management device that performs an optical pulse measurement. ..

The present invention has been made in view of the above background technique, and is a wristband that enables a wristwatch-type health management device equipped with an optical pulse measurement function to be safely worn by a person with sensitive skin. The purpose is to provide.

The present invention has a function of irradiating the surface of the wrist with irradiation light, receiving the reflected light reflected from the wrist, and analyzing the change in the amount of the irradiation light and the reflected light to measure the pulse of the wearer. A wristband used in conjunction with a wristwatch-type health care device.

A removable band body is provided around the wrist, a light transmitting portion capable of transmitting the irradiation light and the reflected light in the thickness direction is provided at a specific portion of the band body, and the health management device is worn on the wrist. The band body is mounted so as to overlap the outer peripheral surface of the band body, and the light transmitting portion is arranged at a position where the irradiation light and the reflected light pass between the health management device and the wrist.

The light transmitting portion is formed of a sheet-like member having light transmitting property. Alternatively, the light transmitting portion is formed by a through hole penetrating the band body in the thickness direction. In this case, the thickness of the inner peripheral edge portion of the light transmitting portion formed by the through hole is such that the band main body is attached to the wrist and the health management device is attached so as to overlap the outer peripheral surface of the band main body. , It is preferable that the health management device is set so as not to come into contact with the skin.

The band body is a band-shaped member longer than the wrist circumference, and the band body can be wrapped around the wrist and fixed by a fixing tool provided on the band body. Alternatively, the band body is a band-shaped member made of an elastic fabric, and the band body and the light transmitting portion are formed in an annular shape as a whole, and the wrist is inserted into the inside of the ring by extending the band body. It can be configured to be fixed around the wrist due to the shrinkage property of the band body.

The wristband of the present invention can be worn on a watch-type health care device in a state where it is difficult to touch the skin, so that the health care device may rub against the skin and feel uncomfortable, or a specific material of the health care device may be applied to the skin. It is possible to prevent symptoms such as allergies, rashes, and eczema from appearing when touched. Moreover, since the light transmitting portion is provided at a predetermined portion of the band body, the optical pulse measurement by the health management device can be performed without any trouble.

It is a perspective view which shows the 4th modification of the wristband of the said embodiment.

Hereinafter, an embodiment of the wristband of the present invention will be described with reference to FIG. The wristband 10 of this embodiment is used in combination with a wristwatch-type health management device 12 having a so-called optical pulse measurement function.

The wristwatch-type health management device 12 includes a main body portion 14 and a belt portion 16. The main body 14 incorporates a light emitting device 14a that irradiates the irradiation light SK toward the wearer's wrist T and a light receiving device 14b that receives the reflected light HK from the wrist T, and the irradiation light SK and the reflected light HK. Pulse measurement is performed by analyzing changes in the amount of light. The belt portion 16 is a member for mounting the main body portion 14 on the back side of the wrist T, and is similar to a belt of a general wristwatch.

The wristband 10 includes a removable band main body 18 around the wrist T, and a light transmitting portion 20 is provided at a specific portion of the band main body 18. The band body 18 is a band-shaped member made of an elastic fabric, and for example, a fabric such as a decorative band worn on a wrist when playing sports can be used. The light transmitting portion 20 is a sheet-like member capable of transmitting the irradiation light SK from the health management device 12 and the reflected light from the wrist TK in the thickness direction, and is, for example, a mesh-like fabric having a certain or higher light transmittance. Or a transparent film or the like can be used.

In the wristband 10, both ends of the band body 18 are connected via a light transmitting portion 20, and the wristband 10 is formed in an annular shape as a whole. It is fixed around the wrist T due to the shrinkage of the main body 18.

As shown in FIGS. 1A and 1B, when the health management device 12 and the wristband 10 are attached to the wrist T, the wristband 10 is first attached to the wrist T, and the health management device 12 is attached to the wristband 10. It is mounted so that it overlaps the outer peripheral surface of the. Then, the light transmitting portion 20 is arranged at a position where the irradiation light SK and the reflected light HK pass between the main body portion 14 of the health management device 12 and the surface of the wrist T.

According to the wristband 10, the wristwatch-type health management device 12 can be worn without touching the skin, so that the health management device 12 may rub against the skin and feel uncomfortable, or a specific material of the health management device 12 may be worn. It is possible to prevent allergies, rashes, eczema and other symptoms from coming into contact with the skin. Moreover, since the light transmitting portion 20 is provided at a predetermined portion of the band main body 18, the optical pulse measurement by the health management device 12 can be performed without any trouble.

The wristband of the present invention is not limited to the form of the wristband 10 described above. For example, the wristband 22 of the modified example shown in FIG. 2A has a band main body 24 made of a band-shaped member made of an elastic fabric formed in an annular shape, and opens a specific portion inside the band main body 24. The structure is such that the above-mentioned light transmitting portion 20 (sheet-like member having light transmitting property) is arranged in the opening thereof. Since the wristband 22 has a structure in which stress when worn on the wrist T is unlikely to be applied to the light transmitting portion 20, there is a feature that a sheet-like member having a relatively weak strength can be used as the light transmitting portion 20.

Further, in the wristband 26 of the modified example shown in FIG. 2B, the light transmitting portion 20 of the wristband 22 is replaced with a light transmitting portion 28 formed of a through hole. The light transmitting unit 28 has a feature that the pulse measurement can be performed with higher accuracy because the transmittance of the irradiation light SK and the reflected light HK becomes very high. However, if the wristband 26 and the health management device 12 are worn and vigorous exercise is performed, the main body 14 of the health management device 12 may touch the skin through the light transmitting portion 28, so that the thickness of the band main body 24 is thick. It is preferable to make the body portion 14 thicker than a certain level so that the main body portion 14 does not easily come into contact with the skin. Alternatively, as in the wristband 26s of the modified example shown in FIG. 2 (c), a flexible resin or rubber having a predetermined thickness formed in a ring shape is formed on the inner peripheral edge of the light transmitting portion 28 made of through holes. A spacer member 30 may be attached so that a certain gap or more is secured between the main body portion 14 and the skin.

Further, in the wristband 30 of the modified example shown in FIG. 3, the band main body 24 of the wristband 22 is replaced with a band main body 34 made of a band-shaped member longer than the wrist circumference, and the band main body 34 is wound around the wrist T and fixed. It can be fixed with the tool 36. The fixative 36 can use, for example, a pair of hook-and-loop fasteners that engage with each other or a pair of magnets that attract each other.
