Hereinafter, the sensor mounting band 40 and the biological information device 1 according to the embodiment of the present invention will be described. The biometric information device 1 shown in this embodiment uses a pulse as biometric information and detects a pulse rate as a biometric information value. For example, the biological information device 1 is capable of confirming biological information (in this embodiment, the pulse rate) even when the user is exercising (running or the like).

FIG. 1 is a schematic diagram showing a state in which the biological information device 1 according to the present embodiment is mounted on a user's arm T (list part).
The biological information device 1 includes a main body 10 having a wristwatch structure, a cable 20 connected to the main body 10, a pulse sensor 30 provided at the tip of the cable 20, and the pulse sensor 30 as a user's arm.

As shown in FIG. 1, the sensor mounting band 40 is mounted in the vicinity of the main body portion 10 in the extending direction of the arm portion T.

The main body 10 is provided with a wristband 12 that is wound around the arm from the twelve o'clock direction of the wristwatch and fixed in the six o'clock direction. With this wristband 12, the main body 10 is detachably attached to the arm. A connector portion 70 is provided on the 6 o'clock side of the main body portion 10, and a connector piece 80 provided on one end side of the cable 20 is detachably attached to the connector portion 70. .

FIG. 2 is a plan view showing the main body 10 as a single unit, and shows a state in which the wristband 12 and the cable 20 are removed.
The main body 10 includes a resin watch case 11 (main body case). Watch case 11
In addition to the current time and date, a liquid crystal display device 13 (display device) with an EL backlight for displaying pulse wave information such as a pitch during running or walking and a pulse rate is provided on the surface side of the display. ing. The liquid crystal display device 13 includes a first segment display area 1 located on the upper left side of the display surface.
31, a second segment display area 132 located on the upper right side, a third segment display area 133 located on the lower right side, and a dot display area 134 located on the lower left side,
In the dot display area 134, various types of information can be displayed graphically.
A body movement sensor (not shown) for obtaining the pitch is built in the watch case 11. As this body motion sensor, an acceleration sensor or the like can be used.

In addition, a control unit 5 that performs various types of control and data processing is provided inside the watch case 11. The control unit 5 analyzes the pulse rate of the user who is the measurement subject based on the detection result (body motion signal) by the body motion sensor and the detection result (pulse wave signal) by the pulse sensor 30 described above, and the liquid crystal Displayed on the display device 13. In this case, since the control unit 5 is also configured with a timer circuit, the normal time can be displayed on the liquid crystal display device 13.

On the outer periphery of the watch case 11, there are provided button switches 111 to 115 that constitute an input device and perform external operations such as time adjustment and display mode switching. Further, on the surface of the watch case, a large button switch 116, 1 which constitutes the input device is also provided.
17 is configured.
The power source of the biological information device 1 is a button-shaped small battery 59 built in the watch case 11, and the cable 20 supplies power from the battery 59 to the pulse sensor 30 and detects the pulse sensor 30. The result is input to the control unit 5 of the watch case 11.

FIG. 3 is a cross-sectional view of the pulse sensor 30.
The pulse sensor 30 has a circuit board 35 disposed inside the case body, and an LED 31, a phototransistor 32, and other electronic components are mounted on the circuit board 35. In the pulse sensor 30, a light transmission window is formed by a light transmission plate 34 made of a glass plate on an upper surface portion (substantial pulse wave signal detection unit) of the sensor frame 36. The LED 31 and the phototransistor 32 have the light emitting surface and the light receiving surface directed toward the light transmitting plate 34 with respect to the light transmitting plate 34, respectively. For this reason, when the finger surface is brought into close contact with the outer surface 441 (contact surface / sensor surface with the finger surface) of the translucent plate 34, the LED 31 emits light toward the finger surface side. At the same time, the phototransistor 32 can receive light reflected from the arm of the user among the light emitted from the LED 31.

In the present embodiment, the LED 31 is an InGaN system (indium-gallium-nitrogen system).
Blue LED, and its emission spectrum has an emission peak at 450 nm. Furthermore, the emission wavelength region of the LED 31 is in the range from 350 nm to 600 nm.
In this example, a GaAsP-based (gallium-arsenic-phosphorus-based) phototransistor is used as the phototransistor 32 in correspondence with the LED 31 having such light emission characteristics. The light receiving wavelength region of the phototransistor 32 itself has a main sensitivity region of 300 nm to 600 nm.
There is also a sensitivity region at 300 nm or less.

When the pulse sensor 30 configured as described above is mounted on the arm T by the sensor mounting band 40 and light is emitted from the LED 31 toward the finger in this state, the light reaches the blood vessel and is caused by hemoglobin in the blood. Part of the light is absorbed and part is reflected. The light reflected from the finger (blood vessel) is received by the phototransistor 32, and the change in the amount of received light corresponds to the change in blood volume (blood pulse wave). That is, when the blood volume is large, the reflected light is weakened, while when the blood volume is small, the reflected light becomes strong. Therefore, if a change in the reflected light intensity is detected, various biological information including the pulse rate can be measured.

FIG. 4A is a front view showing the sensor mounting band 40 as a single unit, and FIG. 4B is a side view of FIG. FIG. 5 is a perspective view showing a state in which the sensor mounting band 40 is wound around the arm portion.
The sensor mounting band 40 includes a band part 41 wound around the arm part T in the circumferential direction, a buckle part 42 to which the band part 41 is hooked when the band part 41 is tightened, and the buckle part 42. A holding part 43 for attaching to the band part 41 is provided. In FIG. 4A, the back surface 41X of the band unit 41 is a surface in contact with the user's arm T, and the front surface 41Y is attached to face outward.

As shown in FIG. 4A, the buckle portion 42 is formed by bending a rod-shaped member to form a substantially rectangular ring. The length of the ring in the width direction is larger than the length of the band part 41 in the width direction, and the band part 41 can be inserted into the ring.
The holding portion 43 is a band-shaped member that forms a ring, and a base end portion 43 a of the holding portion 43 is fixed to the band portion 41. Further, the holding portion 43 is held by winding one side of the buckle portion 42 in the above-described ring. Thereby, the buckle part 42 is attached to the band part 41 through the holding part 43.

The band part 41 has elasticity. That is, when the band portion 41 is wound around the arm portion T and tightened, the band portion 41 extends in the longitudinal direction. Also,
The length L in the longitudinal direction of the band portion 41 is sufficiently long in consideration of the thickness of the arm portion T or the circumferential length of every user. On the other hand, the length L2 of the band portion 41 in the width direction (direction orthogonal to the longitudinal direction) is formed to be sufficiently longer than the length L1 of the pulse sensor 30 (see FIG. 3). That is, when the pulse sensor 30 is mounted, the entire pulse sensor 30 is covered with the sensor mounting band 40. As a result, the pulse sensor 30 is mounted on the user's arm T in a state where the pulse sensor 30 is shielded from the outside of the sensor mounting band 40.

In addition, the band portion 41 includes an external light blocking portion 41a that extends from the base end portion 43a to which the holding portion 43 described above is fixed to the band portion 41 toward one end in the longitudinal direction. Are integrally formed. As shown in FIG. 5, the external light blocking portion 41 a is positioned in a state of being sandwiched between the arm portion T and the buckle portion 42 when the band portion 41 is wound around the arm portion T. Further, the extending length D1 of the external light blocking portion 41a is formed longer than the length D2 of the buckle portion 42, and the external light blocking is performed on the lower side of the buckle portion 42 (the side facing the arm portion T). The part 41a is laid such that there is no gap.

On the surface 41Y side of the band portion 41, a hook portion 44 of Velcro (registered trademark) is provided at a tip portion 41b opposite to the external light blocking portion 41a. On the other hand, between the terminal end of the claw part 44 and the base end part 43a, the Velcro (registered trademark) to which the claw part 44 is attached.
Fabric portion 45 is provided. As is known, the claw portion 44 and the fabric portion 45 can be fixed and peeled freely by human power. Thereby, the fixed position of the band part 41 can be freely adjusted and changed.

As a procedure for winding the band portion 41 around the arm portion T, as shown in FIG.
1 is wound around the arm portion T, the front end portion 41b of the band portion 41 is inserted into the ring of the buckle portion 42, the front end portion 41b is folded back and pulled in the direction opposite to the winding direction, and the claw portion 44 described above is pulled. Is attached to the fabric portion 45. By pulling the band portion 41 in the opposite direction to the winding direction in this way, tension can be generated in the band portion 41. On the other hand, a pressing force F that presses against the arm portion T acts on the pulse sensor 30 by the tension generated in the band portion 41.

On the other hand, the pulse sensor 30 needs to be pressed against the arm portion T with a pressure capable of accurately detecting the pulse rate. Therefore, in order to apply an appropriate pressing force F to the pulse sensor 30 on the band portion 41, as shown in FIG. 4A, the measurement is performed to measure the circumferential length of the arm portion T before winding. And a fixing instructing unit 210 that displays a fixing position (a fixing position at which an appropriate tension can be applied to the band unit 41) based on the length measured by the measuring unit.

As shown in FIG. 4A, the measurement unit 200 includes three measurement regions 201 (indicated by reference numerals 201a, 201b, and 201c from the right side of FIG. 4A). These measurement regions 201a, 201b, and 201c are divided into predetermined lengths in the longitudinal direction of the band portion 41 (the winding direction of the band portion 41), and the respective regions are displayed in different colors.
On the other hand, as shown in FIG. 4A, the fixing instruction unit 210 has three fixing instruction areas 2.
11 (indicated by reference numerals 211a, 211b, and 211c from the right side of FIG. 4A). These fixing instruction areas 211a, 211b, and 211c are divided into predetermined lengths in the longitudinal direction of the band part 41 (the winding direction of the band part 41), and each area is displayed in a different color. Yes.

These three fixed instruction areas 211a, 211b, and 211c correspond to the respective measurement areas 201a, 201b, and 201c. Specifically, the measurement area 201a (green) and the fixed instruction area 211a (green), the measurement area 201b (blue) and the fixed instruction area 211b (blue), the measurement area 201c (red), and the fixed instruction area 211c (red)
And the band portion 41 is fixed to the fixing instruction portion 210 so as to correspond to the color portion displayed in the same color as the color of the measuring portion 200, so that an appropriate pressing force F is applied to the pulse sensor 30. Can act.

Moreover, the pulse sensor 30 is arrange | positioned in the vicinity of the base end part 43a of the holding | maintenance part 43, as shown in FIG. This is because when the pressing force F is applied to the pulse sensor 30, the buckle portion 42 (more specifically, the base end portion 43 a) serving as a reference point for adjusting the tension of the band portion 41 is arranged in the vicinity. This is because a more accurate pressing force F can be managed.

FIG. 6 is an enlarged perspective view showing the external light blocking portion 41a. FIG. 7 is an enlarged cross-sectional view of the external light blocking portion 41a shown in FIG. 5, and shows a state where a gap 48 is generated.
In the process of applying an appropriate tension to the band part 41, when the band part 41 inserted through the buckle part 42 is pulled in the direction opposite to the winding direction, the back surface 41X of the band part 41,
As shown in FIG. 7, friction is generated on the surface 41 </ b> Z of the external light blocking portion 41 a, and the external light blocking portion 41 a is bent upward in the shape of a circle, and between the arm portion T and the external light blocking portion 41 a. There is a possibility that the gap 48 is generated. When this gap 48 occurs, light enters the gap 48 from the outside of the sensor mounting band 40, and when this light hits the pulse sensor 30, a detection error occurs.
Therefore, as shown in FIG. 6, the external light blocking portion 41a is formed in a bag shape having an opening 46 at the end thereof, and a core material 47 having a function as a reinforcing member is inserted into the bag shape inside. It has become so. By inserting the core material 47, the external light blocking portion 41 a becomes the band portion 4.
Compared with the other part of 1 (the part other than the external light blocking part 41a), it becomes hard to bend and prevents the gap 48 described above from occurring.

As shown in FIG. 6, the core material 47 has a substantially rectangular shape, and is formed to have a length D3 that is the same as or slightly smaller than the length D1 that the external light blocking portion 41a extends. The length D4 in the width direction of the core material 47 is formed to be the same length as the inner width of the bag-like portion or slightly smaller. By forming in these dimensions, the core material 47 can be inserted from the opening 46 of the external light blocking part 41a. On the other hand, the material and thickness of the core material 47 can suppress the bending of the external light blocking portion 41a described above, and can be deformed along the shape of the arm portion T when attached to the arm portion T. It can be freely determined within the range. For example, plastic can be used as the material.

Further, the surface 41Z of the external light blocking part 41a has a smaller coefficient of friction than the back surface 41X and the surface 41Y other than the external light blocking part 41a in order to reduce the friction generated between the band 41 and the back surface 41X. Made of low friction material. Also, in order to reduce friction, the surface 41Z
Is formed on a smooth surface without unevenness.
The structure for reducing the friction may be a structure in which a sliding member formed of a low friction material is provided on the surface 41Z, and further, a low friction material may be applied to the surface 41Z. .

According to the sensor mounting band 40 and the biological information device 1 according to the embodiment of the present invention, the buckle portion 42 is provided on one end side in the winding direction, and the tip end portion 41b on the other end side is inserted into the buckle portion 42 to Since the external light blocking part 41a that blocks light incident on the pulse sensor 30 is provided so as to be sandwiched between the arm part T and the buckle part 42 when wrapped around the part T, the buckle part 42 has A gap in the buckle portion 42 generated when the sensor mounting band 40 is inserted can be blocked by the external light blocking portion 41a, and external light does not enter the pulse sensor 30 from the gap portion. it can. As a result, the detection error of the pulse sensor 30 can be prevented from occurring due to light entering from the outside.

Further, since the external light blocking portion 41a is integrally formed in such a manner that the band portion 41 extends from the base end portion 43a toward one end in the longitudinal direction, the external light blocking portion 41a is separated from the band portion 41. The number of parts can be reduced as compared with the case of using a body. Band part 4
When manufacturing 1, since the external light blocking portion 41 a can be manufactured together, the manufacturing becomes easy.

Furthermore, since the external light blocking portion 41a is formed in a bag shape and the core material 47 as a reinforcing member is inserted into the external light blocking portion 41a, the external light blocking portion 41a is the other part of the band portion 41. Compared with (a part other than the external light blocking part 41a), it becomes harder to bend, and the external light blocking part 41a is bent upward in a U-shape so that the arm part T and the external light blocking part 41a It is possible to prevent the gap 48 from occurring between them. As a result, the detection error of the pulse sensor 30 can be prevented from occurring due to the light entering from the gap 48.

Furthermore, since the surface 41Z of the external light blocking portion 41a is formed of a low friction material, it is possible to reduce friction when contacting the back surface 41X of the band portion 41. For this reason, it is possible to prevent the external light blocking portion 41a from bending upward and forming a gap 48 between the arm portion T and the external light blocking portion 41a. As a result, the detection error of the pulse sensor 30 can be prevented from occurring due to the light entering from the gap 48.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made based on the technical idea of the present invention.
In the present embodiment, the sensor mounting band 40 is wrapped around the user's arm T, but may be wound around the user's finger S as shown in FIGS. In this case, the finger part S indicates an arbitrary finger suitable for measurement among the five fingers. The pulse sensor 30
Is wound in a manner that is sandwiched between the finger portion S by the sensor mounting band 40 and covers the entire pulse sensor 30 so as to be shielded from the outside, as in the case of being worn on the arm portion T. The pulse sensor 30 is pressed against the finger S by the tension generated in the sensor mounting band 40. Thus, by attaching the pulse sensor 30 to the base of the finger, the cable 20 can be shortened, and the cable 20 can be prevented from getting in the way during running.

Further, in the present embodiment, as shown in FIG. 1, the sensor mounting band 40 and the main body 10 are mounted side by side in the extending direction of the arm, but the main body 10 is attached to the sensor mounting band 40. You may attach and comprise these integrally. According to this, it is not necessary to provide the wristband 12 for mounting the main body 10, and the manufacturing cost of the biological information device 1 can be reduced. Further, by embedding the cable 20 in the band portion 41, the cable 2
It is also possible to reduce the cost by eliminating the need for zero routing. Also, cable 2 to the user
There is no discomfort due to 0 being bulky.

On the other hand, in the present embodiment, the external light blocking portion 41a is configured to be integrally formed in a mode in which the band portion 41 extends from the base end portion 43a toward one distal end in the longitudinal direction. It may be a separate body from 41. For example, the external light blocking portion 41a may be sewn to the base end portion 43a of the band portion 41 in a subsequent process. This also makes it difficult for light from the outside to enter the pulse sensor 30 as in the structure described in the embodiment.

Furthermore, although the dimension D4 of the core material 47 is formed to be substantially equal to the inner width of the bag-shaped portion formed in the external light blocking portion 41a, the core material 47 is formed by extending the external light blocking portion 41a. In order to prevent bending in the direction, if the dimension D3 of the core material 47 is secured, it is not necessary to increase the dimension D4 of the core material 47 to the full inner width of the bag-like portion. That is, it may be a part of the core material 47 in the width direction. Furthermore, a plurality of core materials may be provided by being divided in the width direction.

Further, even if the external light blocking portion 41a is not formed in a bag shape and the core material 47 is inserted, the hardness of the external light blocking portion 41a is less likely to bend than the portions other than the external light blocking portion 41a. It can also be formed into a solid. For example, when the band portion 41 and the external light blocking portion 41a are integrally manufactured, the thickness of the external light blocking portion 41a is thicker than that of the other portions, so that it is harder than the other portions. can do. Alternatively, a core material can be embedded in the external light blocking portion 41a in advance. Moreover, the core material 47 as a reinforcing member can be sewn or attached to the outer side of the external light blocking portion 41a. Further, the core material is formed in a bag shape and inserted into the outside of the external light blocking portion 41a, or the core material is formed in a strip shape and is detachably wound around the external portion of the external light blocking portion 41a (attachment) You may do it. Thereby, the external light blocking part 41a can be formed to a hardness that is difficult to bend.
In addition, when providing this core material 47 in the outer side of the surface 41Z of the external light shielding part 41a, the surface of this core material 47 is formed with a low friction material, and the external light shielding part 41a is a dogleg shape on the upper side. Bent to
It is also possible to prevent the gap 48 from being generated between the arm portion T and the external light blocking portion 41a.

In the present embodiment, the surface 41Z of the external light blocking portion 41a is formed of a low friction material, but the back surface 41X of the band portion 41 that is in contact with the surface 41Z is formed of a low friction material. Also good. Thereby, it is possible to make it difficult to bend the external light blocking portion 41a.

On the other hand, in this Embodiment, it demonstrated that the pulse rate was displayed as biometric information, but it is not restricted to a pulse rate. For example, as biological information, body temperature, blood pressure, pulse wave, oxygen saturation in arterial blood, body movement, and the like can be given as specific examples.
