When performing the measurement using the technique described in Patent Document 1 described above, the measurement unit (wearing unit) including the light emitting unit and the light receiving unit is brought into close contact with the skin of the person who performs the training (measurement target person). Need to be fixed. On the other hand, during training, the measurement subject moves each part to perform exercise, and thus there is a problem that it is difficult to fix the exercise assisting device at an appropriate position. That is, there is a problem that the fixed position is displaced due to the movement, and it is difficult to measure at the same place. In addition, if there is a slight gap between the mounting portion and the skin due to exercise, extraneous light unnecessary for measurement enters through the gap, which makes it impossible to perform accurate measurement. ..

If the mounting portion of the exercise assisting device is firmly fixed using a belt or the like so that it does not come in close contact with the skin of the measurement subject, the above problems can be prevented. However, if fixed in this way, the portion where the measurement is performed is unnecessarily tightened, and the person being measured feels uncomfortable, or the skin blood flow is obstructed, which hinders training. There will be problems.

The present disclosure has been made to solve the above problems, and provides a fixing belt capable of appropriately fixing a biometric information collection sensor to a measurement target site of a person who performs exercise such as training. The purpose is to

The fixed belt 1 is made of a flexible and stretchable thin plate material processed into a predetermined band shape. The fixed belt 1 is made of a light-shielding material. More specifically, the fixed belt 1 is made of a material that shields at least light in the near infrared region. More specifically, the fixed belt 1 is preferably made of a material that at least blocks light in the wavelength range of about 700 nm to 1.2 μm.

In the present embodiment, the fixing belt 1 is formed by laminating a thin plate-like material into a band shape, in which a front surface portion 11 formed of a cloth-like material and a back surface portion 12 formed of a rubber thin plate material having a light-shielding property are bonded together. The description will be made by applying it to an example (see FIG. 1B).

More specifically, in the present embodiment, the front surface portion 11 is made of a cloth material to which the hook portion of the surface fastener (male side of the surface fastener) can be attached and peeled off. The following description is applied to an example made of a thin plate material made of chloroprene rubber. Note that, hereinafter, the side on which the front surface portion 11 of the fixed belt 1 is arranged is referred to as the front side or the front surface, and the side on which the rear surface portion 12 is arranged is also referred to as the back side or the rear surface. By using a rubber material for the back surface portion 12 as described above, contact resistance is generated due to the nature of the material, so that slippage of the portion where the biometric information collection sensor 60 and the fixed belt 1 are in contact is unlikely to occur. , It becomes easy to obtain accurate biometric information.

The fixing belt 1 has flexibility, elasticity, and a light-shielding property that shields at least near-infrared rays, and its front side surface is made of a material that can be fixedly attached and peeled off by a fixing portion 5 described later in detail.

The fixed belt 1 mainly includes a sensor placement portion 2, a first strip-shaped portion 3, a second strip-shaped portion 4, and a fixed portion 5. The sensor placement section 2 is a section that is placed so as to cover the entire biometric information collection sensor 60 when fixing the biometric information collection sensor 60 placed at the measurement target site.

More specifically, referring to FIG. 1A, the sensor placement portion 2 includes a substantially trapezoidal first strip-shaped portion 3 extending in the longitudinal direction of the fixed belt 1 (the left-right direction in FIG. 1A). It is a portion sandwiched between the second belt-shaped portions 4 and located substantially at the center of the fixed belt 1 in the longitudinal direction. The sensor placement portion 2 includes sides 22 and 23 extending parallel to the longitudinal direction, sides 24 and 25 extending substantially parallel to the direction diagonally intersecting the longitudinal direction, and a width direction of the fixed belt 1 (upper and lower sides in FIG. 1A). Direction) and has a substantially hexagonal shape surrounded by virtual lines 21a and 21b extending substantially parallel to the (direction).

The virtual line 21a is a virtual line at the boundary between the sensor placement part 2, the first strip-shaped part 3 and the sensor placement part 2, and the virtual line 21b is a virtual line at the boundary between the sensor placement part 2 and the second strip-shaped part 4. Is the line of. The sensor placement unit 2 has a size capable of covering the entire biometric information collection sensor 60 so as to prevent unnecessary light from entering between the mounting unit 61 and the measurement target site. Note that, in FIG. 1A, the arrangement position of the biological information collection sensor 60 in the sensor arrangement unit 2 is indicated by a broken line for the sake of explanation.

When fixing the biometric information collection sensor 60 arranged at the measurement target site such as the upper limb or the lower limb of the measurement target person, the first strip-shaped section 3 and the second strip-shaped section 4 are wrapped around the measurement target site and fixed. It is the part that is done.

The first strip-shaped portion 3 extends in the longitudinal direction away from the sensor placement portion 2 from a portion closer to one side in the width direction of the sensor placement portion 2 on the side of the imaginary line 21a (upper side in FIG. 1A). It is extended. In addition, the second strip-shaped portion 4 is opposite to the first strip-shaped portion 3 from the portion closer to the other side (lower side in FIG. 1A) in the width direction on the side of the virtual line 21b of the sensor placement portion 2. It also extends in the same direction.

Each of the first strip-shaped portion 3 and the second strip-shaped portion 4 has a substantially trapezoidal shape whose width becomes narrower as the distance from the sensor placement portion 2 increases. To be more specific, the first strip-shaped portion 3 is configured such that the long side 32 that extends obliquely in the same direction as the side 22 of the sensor placement portion 2 and the long side 32 that approaches the long side 32 as the distance from the sensor placement portion 2 increases. It has a substantially trapezoidal shape having an extended long side 31 (see FIG. 1A). The long sides 31 and 32 are examples of the first long side.

In addition, the second strip-shaped portion 4 includes a long side 42 extending in the same direction as the side 23 of the sensor placement portion 2 and a long side 41 extending obliquely so as to approach the long side 42 as the distance from the sensor placement portion 2 increases. It has a substantially trapezoidal shape (see FIG. 1A). The long sides 41 and 42 are an example of the second long side.

That is, the first strip-shaped portion 3 and the second strip-shaped portion 4 are substantially trapezoidal strip-shaped portions that extend in the longitudinal direction from the respective portions that are offset in the width direction and that face the longitudinal direction of the sensor placement portion 2. Is. Then, when wrapped around the measurement target site, the long side 31 of the first strip-shaped portion 3 on the side of the second strip-shaped portion 4 extends obliquely so as to approach the long side 32 as the distance from the sensor placement portion 2 increases. There is.

Similarly, the long side 41 of the second strip-shaped portion 4 on the side of the first strip-shaped portion 3 when being wound around the measurement target portion is also inclined so as to approach the long side 42 as the distance from the sensor placement portion 2 increases. It is extended. That is, the long sides 31 and the long sides 42 extend so as to be separated from each other when the first strip-shaped portion 3 and the second strip-shaped portion 4 are wound around the measurement target site.

On the back surfaces of the end portions of the first strip-shaped portion 3 and the second strip-shaped portion 4 on the side remote from the sensor placement portion 2, there are provided fixing portions 5 that can be attached to the surface portion 11 and detachably fixed. Has been. The fixing portion 5 is a portion that fixes the first strip-shaped portion 3 and the second strip-shaped portion 4 wound around the measurement target site.

In the present embodiment, the fixing portion 5 is applied to an example which is a portion on the hook side of a known surface fastener (the side that is raised in a hook shape, that is, the male side of the surface fastener), and will be described below. The fixing portion 5 may be a fixing member having another known structure as long as it can be attached to the front surface of the fixing belt 1 and can be peeled off and fixed.

<2. How to use>
Next, a method of using the fixed belt 1 according to this embodiment will be described. In the following description, the fixing belt 1 is applied to an example used for fixing the biological information collection sensor 60 mounted on the thigh of the measurement subject, and the following description will be given. The fixing belt 1 may be used to fix the biological information collecting sensor 60 arranged on the lower leg or the upper arm.

First, the biometric information collection sensor 60 is placed at the measurement target site on the thigh of the measurement target person. Specifically, the not-shown mounting portion 61 of the biometric information collection sensor 60 is arranged so as to be in close contact with the portion of the measurement subject's thigh where the measurement is performed.

Then, the fixing belt 1 is arranged so that the sensor arrangement unit 2 covers the entire biological information collection sensor 60. Specifically, the fixing belt 1 is oriented so as to intersect the thigh of the measurement subject, and the sensor placement unit 2 is placed so as to cover the entire biological information collection sensor 60 (see FIG. 2A). .. At this time, the back surface of the fixed belt 1, that is, the back surface portion 12 is directed toward the biological information collecting sensor 60 side.

Then, the first strip 3 is wrapped around the thigh. At this time, the first strip portion 3 is wound such that the long side 32 is substantially parallel to the side 22. That is, the first strip-shaped portion 3 is wrapped around the thigh so that the portion on the long side 31 side of the first strip-shaped portion 3 does not protrude as much as possible into the region around which the second strip-shaped portion 4 is wrapped. After the first strip 3 is wrapped around the thigh, the fixing portion 5 at the end thereof is attached to the corresponding portion of the surface (surface portion 11) of the fixing belt 1 to fix the first strip 3 ( See FIG. 2B.).

Then, the second strip 4 is wrapped around the thigh. At this time, the portion of the second strip-shaped portion 4 on the long side 41 side is wound so as not to overlap the already wound first strip-shaped portion 3. After the second band-shaped portion 4 is wrapped around the thigh, the fixing portion 5 at the end thereof is attached to the surface of the fixing belt 1 to fix the second belt-shaped portion 4 (see FIG. 3).

Alternatively, the second strip portion 4 may be wound first, and then the first strip portion 3 may be wound around the thigh. After the fixing belt 1 is wrapped around the thigh, it is confirmed whether the biometric information collection sensor 60 is correctly fixed at a desired position, and if necessary, the fixing by the fixing belt 1 is adjusted.

Specifically, it is confirmed that the biometric information collection sensor 60 is sandwiched between the skin of the measurement subject and the sensor placement unit 2 and is appropriately placed at a desired position. Also, it is confirmed that the entire biometric information collection sensor 60 is completely covered by the sensor placement unit 2 and is placed so that external light does not enter. When the fixing belt 1 is tightly wound and the person to be measured is hard to exercise, the fixing portion 5 is peeled off and the first strip-shaped portion 3 and the second strip-shaped portion 4 are rewound. Adjust the winding strength.

Since the fixed belt 1 configured as described above has a band shape having flexibility and elasticity, it is possible to easily arrange the biological information collection sensor 60 by winding the fixed belt 1 around the measurement target site. Can be fixed to. Further, since the fixing portion 5 which is attached to the front surface of the first strip-shaped portion 3 and the second strip-shaped portion 4 and which can be peeled off is provided, the fixing belt 1 can be fixed and removed. It's easy. Further, since the fixed belt 1 expands and contracts even in a state of being wound around the measurement target site, the measurement target person can easily perform a desired exercise.

The fixed belt 1 is made of a light-shielding material. Therefore, it is possible to prevent extraneous light that hinders accurate measurement from entering between the measurement target portion and the mounting portion 61. Therefore, it is possible to perform accurate measurement using the biometric information collection sensor 60 even while the measurement subject is exercising such as training.

Further, the first strip-shaped portion 3 and the second strip-shaped portion 4 extend from positions displaced in the width direction of the sensor placement portion 2. Therefore, the first strip-shaped portion 3 and the second strip-shaped portion 4 can be independently wound around the measurement target site. For example, the thickness of the thigh or upper limb is usually different on the trunk side and the peripheral side. For this reason, when the biological information collection sensor 60 arranged in those portions is fixed by winding a known belt having a substantially rectangular shape, the trunk side is tightened too much or the peripheral side is tightened. It becomes too loose and it is difficult to fix it sufficiently.

On the other hand, in the fixed belt 1 according to the present embodiment, the first strip-shaped portion 3 and the second strip-shaped portion 4 can be independently wound. That is, each can be independently wrapped around the measurement target site according to the thickness of the thigh or the upper limb. Therefore, even when the biometric information collection sensor 60 is arranged in a portion having a different thickness depending on its location, such as a thigh or an upper limb, the biological information collection sensor 60 can be properly fixed. Further, since the biological information collecting sensor 60 is firmly fixed, it is possible to prevent the tightening of the biological information collecting sensor 60 from being unnecessarily tight.

Further, the long side 31 of the first strip-shaped portion 3 is provided so as to be inclined in a direction away from the second strip-shaped portion 4 as it is wound around the measurement target site. The long side 41 of the second strip portion 4 is also provided so as to be inclined in a direction away from the first strip portion 3 as it is wound around the measurement target site.

Therefore, the biometric information collection sensor 60 can be fixed by wrapping the fixing belt 1 around the target site without the first strip 3 and the second strip 4 overlapping. If the first belt-shaped portion 3 and the second belt-shaped portion 4 overlap when the fixing belt 1 is wound, when the person to be measured exercises, the overlapped portion is displaced, so that the winding becomes loose and the living body There is a possibility that the information collection sensor 60 may be unfixed.

On the other hand, since the fixed belt 1 can be wound around the measurement target site without the first strip-shaped portion 3 and the second strip-shaped portion 4 overlapping with each other, there is no such possibility. Further, in order to prevent the winding from becoming loose, it is also possible to prevent a portion where the winding of the fixed belt 1 becomes unnecessarily strong.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the invention. For example, a plurality of through holes 6 may be provided in the first strip-shaped portion 3 and the second strip-shaped portion 4 (see FIG. 4).

By providing a plurality of such through holes 6, it is possible to secure the air permeability of the portion around which the fixed belt 1A is wound, and reduce the discomfort of the measurement subject. In addition, when the through holes 6 are provided, it is preferable to provide a predetermined interval so as not to reduce the strength of the fixing belt 1A. For example, as shown in FIG. 4, it is preferable that each through hole 6 be provided at a position displaced in the width direction and the longitudinal direction to ensure a certain distance. The number of through holes 6 is not limited to the number shown in FIG. 4, and it is possible to provide a larger number of through holes 6 or a smaller number than the illustrated numbers. Good. Further, the through hole 6 may be provided in only one of the first strip-shaped portion 3 and the second strip-shaped portion 4.

In the above embodiment, the fixing belt 1 is described as being applied to an example in which the entire fixing belt 1 is made of a light-shielding material. However, for example, only the sensor placement portion 2 is made of a light-shielding material. May be For example, the sensor placement portion 2 is made of a thin plate material made of a rubber material having a light shielding property, and the first strip-shaped portion 3 and the second strip-shaped portion 4 are made of a material having excellent breathability and elasticity. It may be composed of a certain material. Alternatively, the portion of the sensor placement portion 2 that covers the entire biological information collection sensor 60 when fixed is made of a light-shielding material, and the other portion is made of a material having excellent breathability and elasticity. You may. By doing so, it is possible to obtain the inexpensive fixed belt 1 having excellent air permeability.

A rubber material having a light blocking property is used on the back side of the sensor placement portion 2. By doing so, the contact resistance when the sensor placement portion 2 and the surface of the biological information collection sensor 60 (the portion on the side opposite to the mounting portion 61) contact is increased, and the biological information collection sensor 60 and the fixed belt 1 are connected. Are integrated, and the deviation is less likely to occur. Therefore, the biometric information collecting sensor 60 is accurately fixed, and accurate biometric information is easily obtained. It should be noted that other known material having a large contact resistance with the biometric information collection sensor 60, such as light-shielding property, flexibility, and stretchability, may be used for the portion on the back side of the sensor placement unit 2.

In the above-described embodiment, the description has been given by applying to the example in which the sensor placement portion 2 has a substantially hexagonal shape, but it may have another shape. For example, the sensor placement unit 2 may have a substantially rectangular shape. That is, the sides 24 and 25 may have a shape extending in a direction substantially orthogonal to the sides 22 and 23. Alternatively, it is possible to prevent unnecessary extraneous light from entering the biometric information collection sensor 60, and the first strip-shaped portion 3 and the second strip-shaped portion 4 can extend from portions that are offset in the width direction. Any other known shape may be used as long as it can be formed.

In the above-described embodiment, the fixing belt 1 is applied to the example in which the biological information collecting sensor 60, which is the tissue oxygen concentration monitor, is fixed. On the other hand, the fixing belt 1 may be used to fix another known biological information collecting sensor. For example, the fixed belt 1 is a pulse oximeter or other type of biometric information collection sensor, and other known biometric information collection that measures biometric information using ultraviolet light, visible light, near infrared light, infrared light, or the like. It may be used to fix a sensor or the like. Alternatively, the fixing belt 1 may be used to fix other known biological information collecting sensors that are attached to the measurement target site and collect biological information, and that do not use light.

Further, for example, the present invention is not limited to the application to the above-described embodiments, and may be applied to an embodiment in which these embodiments are appropriately combined, and is not particularly limited.
