Description

  The present invention relates to a biometric device equipped with a sensor for measuring biological information, for example, a pulse wave measuring device for measuring a pulse wave, a body temperature measuring device for measuring body temperature, and a sweat measurement for measuring the degree of sweating. The present invention relates to a biometric device for mounting a device or the like on, for example, a wrist, an ankle, or a neck.

  2. Description of the Related Art Conventionally, in exercise training, as one of methods for realizing exercise training without excess or deficiency, a method of adjusting exercise amount using a heart rate calculated from exercise intensity as an exercise training index is known.

  In other words, the exercise intensity is an index indicating the intensity of exercise and the load on the body, and indicates the percentage of exercise with the maximum oxygen intake taken as 100%. When exercise training is performed using such exercise intensity, a target exercise intensity, which is the target exercise intensity, is set, and the target heart rate, which is the heart rate corresponding to the target exercise intensity, Is a way to manage.

  In such exercise intensity, the greater the value of exercise intensity, the greater the energy consumption, the greater the load on the body, the sugar accumulated in the liver and muscles as the energy source, and vice versa. Uses lipid as an energy source.

  In view of these, there is much debate about whether to use carbohydrates or lipids as energy sources, and proposals to apply this idea to improving physical strength, diet, prevention of lifestyle-related diseases, etc. Many.

  By the way, the value of exercise intensity is not specified by the exercise to be performed and its type, and even if the same exercise is performed, the value varies depending on the individual. Since energy consumption during exercise is roughly proportional to oxygen intake, it is necessary to measure oxygen intake during exercise. However, this requires a large-scale device and specialized knowledge, and it is generally difficult to know the numerical values.

  For this reason, in recent years, instead of measuring oxygen intake during exercise, it is quantified based on the heart rate of the heart that is roughly proportional to the oxygen intake, and the load on the body is grasped by the heart rate. ing.

  You can measure your heart rate by placing your finger on the inside or neck of your wrist and feeling the skin vibrating with the heartbeat. When heart rate is set to be used as an exercise training index, there is a demand for measuring heart rate even during exercise or immediately after training. However, a heart rate monitor that can easily measure the heart rate has been demanded. In recent years, many electronic heart rate monitors have been proposed.

  As such an electronic heart rate monitor, generally an electrocardiogram detection method is widely known.For example, a belt-like pulse wave detection unit having an electrode for detecting a pulse wave is attached to a finger or a chest. Some display information is transmitted to a separate display unit by wire or wireless. The display unit obtains and displays the heart rate from the cycle of the pulse wave detected by the pulse wave detection unit attached to the arm or the like. Of course, there is also an integrated pulse wave detection unit and display unit.

In the pulse wave detector, in addition to the electrode type using such electrodes, an optical type that captures changes in blood flow with light and a pressure that measures changes in blood pressure with pressure using an electrostatic pressure sensor There are also formulas.
By the way, in such an electronic heart rate monitor, in order to be able to measure the heart rate even during exercise or immediately after training, Patent Document 1 (Japanese Patent Laid-Open No. 53-32765) discloses a pulse. A wrist-worn biometric device equipped with a pulse wave measurement sensor for measuring waves has been proposed.

That is, as shown in FIG. 20, a health management wristwatch 100 of Patent Document 1 has been proposed as a wrist-worn biometric device. In this health management wristwatch 100, a pulse wave measurement sensor 104 and a body temperature measurement sensor 106 are arranged on the back side of the wristwatch body 102 on the wrist side. Then, as shown in FIG. 21, by attaching a wristwatch band 108, which is a conventional type watchband, to the wrist, and by positioning the wristwatch body 102 on the palm side, the body temperature measured by the body temperature measuring sensor 106 The heart rate obtained from the pulse wave period detected by the pulse wave measuring sensor 104 is displayed on the display unit 110 of the wristwatch body 102.
Japanese Patent Laid-Open No. 53-32765 Utility Model Registration No. 2553097 JP-A-11-239506 Japanese Patent Laid-Open No. 10-146322 JP 2007-143812 A Japanese Patent No. 3487919

  By the way, in such a health management wristwatch 100 as disclosed in Patent Document 1, in order to perform accurate measurement by the pulse wave measurement sensor 104 and the body temperature measurement sensor 106, It is necessary to press the pulse wave measuring sensor 104 and the body temperature measuring sensor 106 arranged on the back surface in close contact with the palm side of the wrist.

  However, since this health management wristwatch 100 uses a wristwatch band 108 that is a conventional type wristwatch band, it cannot cope with the difference in the thickness of the wrist of the wearer.

  That is, when the wearer's wrist is thinner than the wristwatch band 108, the pulse wave measurement sensor 104 and the body temperature measurement sensor 106 arranged on the back side of the wrist of the wristwatch body 102 are placed on the palm side of the wrist. It is impossible to carry out accurate measurement by the sensor without being in close contact and being pressed with an appropriate pressing force. In this case, the wristwatch main body 102 may be displaced during exercise, training, or the like, and the pulse wave measurement by the pulse wave measurement sensor 104 cannot be performed.

  In order to measure the pulse wave with the pulse wave measurement sensor 104, it is necessary to position the wristwatch band 108 at the position of the ulnar process, and the wristband 108 and the watch body 102 are lifted by the ulnar process. It becomes a state. As a result, the pulse wave measurement sensor 104 and the body temperature measurement sensor 106 are in close contact with the palm side of the wrist and are not pressed with an appropriate pressing force, so that accurate measurement by the sensor cannot be performed.

Furthermore, the wristwatch band 108, which is a conventional type of watch band, lacks fit during exercise and training, and may impede exercise and training. The operation of attaching the wristwatch band 108 to the wrist also requires a complicated operation such as locking with an intermediate stop member or the like, and cannot be attached with a so-called one-touch operation.

  Instead of the conventional type wristband 108 of Patent Document 1, it is also conceivable to use a wrist sphygmomanometer cuff as disclosed in Patent Document 2 (Utility Model Registration No. 2553097).

  As shown in FIG. 22, the wrist sphygmomanometer cuff 200 disclosed in Patent Document 2 includes an air bag 208 disposed between an outer sheet 204 and an inner sheet 206 forming a belt body 202. A special-shaped curler 210 having a cross-section “T” shape is arranged between 208 and the outer sheet 204.

  However, the wrist sphygmomanometer cuff 200 of Patent Document 2 measures the blood pressure by inflating the band 202 by injecting air into the air bag 208, thereby tightening the wrist and measuring the blood pressure. In addition to this, a device for injecting air is also required separately.

Therefore, it cannot be applied to a wrist-worn biometric device equipped with a sensor that measures biological information such as heart rate and body temperature during exercise and training.
It is also conceivable to use a watch band as disclosed in Patent Document 3 (Japanese Patent Laid-Open No. 11-239506) instead of the conventional type wristband 108 of Patent Document 1.

  As shown in FIG. 23, the watch band 300 is constituted by an integral member 302 made of leather or the like, and a core member 304 made of a shape memory alloy wire, which is fixed in a substantially C shape in advance, is formed therein. The watch band 300 has a substantially C shape similar to the shape of the core material 304.

  As a result, it can be easily attached with one hand simply by pressing the opening 306 of the watch band 300 against the wrist, and is naturally held by the wrist due to the superelastic effect of the shape memory alloy. The mechanism for adjusting the height can be omitted.

  However, since the watch band 300 of Patent Document 3 is substantially C-shaped, the wrist is generally tightened by the superelastic effect of the shape memory alloy, and biological information such as heart rate and body temperature is measured. When applied to a wrist-worn biometric device equipped with a sensor that does this, there will be a lack of fit during exercise and training, and sometimes the wrist is thick and the tightening force is strong and painful In some cases, it may interfere with exercise and training.

  The wrist is not circular and its thickness is smaller than the length in the width direction. In most cases, the so-called thick wrist is long in the width direction when the wrist is viewed from the palm side or the back side of the hand. In other words, when viewed as such, the wrist shows a greater individual difference in the length in the width direction than in the thickness.

  For this reason, in the watch band 300 of Patent Document 3, the opening 306 opens in the width direction of the wearer's wrist, so that the wristwatch body 301 is further floated. In other words, the fit changes greatly depending on the wearer.

  Further, in order to measure the pulse wave with the pulse wave measurement sensor, the watch band 300 needs to be positioned at the position of the ulnar process. However, since the watch band 300 is substantially C-shaped, it covers the entire wrist. Thus, the watch band 300 and the watch body 301 are floated by the ulna process. As a result, the pulse wave measurement sensor is in close contact with the palm side of the wrist and is not pressed with an appropriate pressing force, so that accurate measurement by the sensor cannot be performed.

For this reason, Patent Document 4 (Japanese Patent Laid-Open No. 10-146322) proposes a carotid artery wave detecting device 400 having a structure as shown in FIG.
The carotid artery wave detecting device 400 of Patent Document 4 includes a gripping device 402 that is curved and biased in the direction of diameter reduction by an elastic restoring force.

The gripping device 402 includes a curved first arm 404 and a second arm 408 that is rotatably connected to the first arm 404 by a hinge mechanism 406.
A plurality of pulse wave detection probes 410 are connected to one end portion of the first arm 404 so as to be slidable and swingable in the protruding direction.

  However, in the carotid artery wave detection device 400 of Patent Document 4, a plurality of pulse wave detection probes 410 are connected to one end portion of the first arm 404 so as to be slidable and swingable in the protruding direction. The structure is complicated and large, and the cost is high. Even if it can be applied to relatively large diameter parts such as the neck, it can be applied to wrists, ankles, fingers, etc. It is not suitable for application to a relatively small diameter portion of a living body.

  In this case, since the plurality of pulse wave detection probes 410 slidable in the projecting direction and swingable are provided, the feeling of wearing is not good, and the shape and size differ depending on individual differences. Depending on the attachment site, it is difficult for the pulse wave detection probe 410, which is a sensor part, to stably contact and press the part to be measured.

  Further, as shown in FIG. 25, Patent Document 5 (Japanese Patent Laid-Open No. 2007-143812) proposes a wearable electronic device 500 that can prevent a dropout from a wearing target and has improved wearability. Has been.

  The wearable electronic device 500 of Patent Document 5 is configured in an annular shape in which a belt-like belt body 502 is curved and partly opened. A flexible auxiliary belt 506 is connected to one end portion 504 of the belt main body 502, and the front end portion of the belt main body 502 is overlapped with the other end portion of the belt main body 502, tightened, and fastened. The opening 508 is configured to be closed.

  However, in such a structure that is fastened and fastened by the flexible auxiliary belt 506, the pressing force of the sensor changes depending on the tightening condition of the user. As a result, a stable sensor output cannot be obtained, and accurate measurement data cannot be obtained. In other words, when the tightening force is strong, the sensor sensitivity becomes saturated and cannot be measured. Conversely, when the tightening force is weak, the sensor output is insufficient or the distribution is deteriorated. Therefore, in any case, accurate measurement data cannot be obtained.

Further, Patent Document 6 (Japanese Patent No. 3487919) proposes a portable pulse wave measuring device 600 having a structure as shown in FIG.
The portable pulse wave measuring device 600 of Patent Document 6 includes a calculation processing means in a main body 602, and a pulse wave detection sensor 606 is provided in a first band 604 attached to one side of the main body 602. ing.

  A second band 608 is attached to the other side of the main body 602, and a force in a direction in which the pulse wave detection sensor 606 is brought into close contact with the living body 610 is generated in the vicinity of the support portion of the second band 608. An elastic member 612 is provided.

However, the portable pulse wave measuring device 600 of Patent Document 6 has a structure in which the first band 604 and the second band 608 are fastened together.
Therefore, the pressing force of the sensor changes depending on the tightening condition of the user. As a result, a stable sensor output cannot be obtained, and accurate measurement data cannot be obtained. In other words, when the tightening force is strong, the sensor sensitivity becomes saturated and cannot be measured. Conversely, when the tightening force is weak, the sensor output is insufficient or the distribution is deteriorated. Therefore, in any case, accurate measurement data cannot be obtained.

  Further, in the portable pulse wave measuring device 600 of Patent Document 6, the pulse wave detection sensor 606 is provided in the first band 604, so that it can be electrically connected to the main body 602 provided with arithmetic processing means. It is necessary to provide the lead wire 614 on the first band 604, which is complicated and expensive. In addition, the lead wire 614 may be disconnected during exercise, training, etc., and accurate measurement data can be obtained. There is a possibility that it cannot be obtained.

  In view of such a current situation, the present invention has a good wearing feeling, and even in a worn part having a different shape and size depending on individual differences, it does not float, and a sensor such as a sensor for measuring pulse waves, An object of the present invention is to provide a biometric device capable of performing accurate measurement using a sensor without being displaced during exercise, training, or the like while being in close contact with a wearing site and being pressed with an appropriate pressing force. And

  In addition, the present invention can cope particularly with the difference in the thickness of the wrist of the wearer, the band does not float due to the ulnar process, and a sensor such as a pulse wave measurement sensor is used on the palm side or the back of the hand. Providing wrist-worn biometrics that can be pressed with an appropriate pressing force with close contact with the wrist side, and that can be accurately measured with a sensor without shifting position during exercise, training, etc. The purpose is to do.

  Furthermore, the present invention has a good fit during exercise and training, and even when the wrist is thick, it does not cause pain, does not interfere with exercise and training, and can be attached and detached with a so-called one touch. An object of the present invention is to provide a wrist-worn biometric device.

The present invention has been invented in order to achieve the problems and objects in the prior art as described above.

Accurate measurement by the sensor can be performed without shifting the position during training or training.

  In addition, since it is only necessary to provide such a sensor and a pressing means that opposes the sensor and the attached portion of the living body, the other portions can be appropriately opened, so that it is attached to the wrist, for example. In some cases, the wrist may have a structure in which the ulna side or the rib side is opened, and the biometric device can be attached to and detached from the wrist from the open portion of the wrist on the ulna side or the rib side by one-touch.

Moreover, by adopting a configuration in which the ulna side of the wrist is open, the biometric device is not brought into a floating state by the ulna process, and accurate measurement by the sensor can be performed.
In addition, since the mounting part is supported by such a sensor and the pressing means facing the sensor and the mounting part of the living body, the rotation of the biometric device around the mounting part, for example, the wrist Therefore, accurate measurement by the sensor can be performed without shifting the position during exercise or training.

Even in this case, there is no pain and there is no risk of obstructing exercise or training.

Moreover, the biometric apparatus of the present invention is characterized in that the pressing means is formed from a protruding pad.
In this way, if the pressing means is formed of a protruding pad, the mounted portion is supported by the sensor and the protruding pad that faces the sensor and the mounted portion of the living body, and the sensor is the measuring portion of the living body. Will be pressed.

  Therefore, for example, by configuring the projecting pad from an elastic member, the feeling of wearing by the projecting pad is good, and the projecting pad is projecting, so the shape and size of the projecting pad varies depending on individual differences. Sensors such as pulse wave measurement sensors do not float even at different wearing parts, and the sensors are in close contact with the wearing parts and pressed with an appropriate pressing force, and the position is shifted during exercise, training, etc. Therefore, accurate measurement by the sensor can be performed.

  In addition, for example, by constructing the protruding pad from an elastic member, the fit is good during exercise and training, and even if the wrist is thick, there is no possibility of pain and obstructing exercise or training Nor.

  The biometric device of the present invention is characterized in that the protruding pad functions as a positioning means when the biometric device is mounted on the mounted portion of a living body.

Moreover, the biometric device of the present invention is characterized in that the pressing means is provided in a band connected to one end of the measuring device main body.
In this way, if the pressing means is provided in the band connected to one end of the measuring apparatus main body, the sensor and the pressing means provided in the band facing the sensor and the living body mounting portion sandwich the sensor. The mounting site is supported, and the sensor is pressed against the measurement site of the living body with a constant pressing force, for example, by giving elasticity to the band itself.

  Therefore, the wearing feeling is also good, and even the wearing parts of different shapes and sizes due to individual differences do not float, and the sensor such as a pulse wave measurement sensor is in close contact with the wearing part and is appropriate. Accurate measurement by a sensor can be performed without being displaced during exercise, training, and the like by being pressed by a pressing force.

  In addition, for example, by giving elasticity to the band itself, the fit feeling is good during exercise and training, and even when the wrist is thick, there is no pain and there is no possibility of obstructing exercise or training .

The biometric apparatus according to the present invention is characterized in that the pressing means is formed from a part of a band.
Thus, by forming the pressing means from a part of the band, for example, by projecting the end of the band, the pressing means can be easily configured by injection molding or the like, resulting in a complicated configuration. The cost can also be reduced.

  In this way, by forming the pressing means from a part of the band, the mounted portion is supported by the sensor and the band facing the sensor and the mounted portion of the living body, and, for example, the band itself is elastic. By holding the sensor, the sensor is pressed against the measurement site of the living body with a constant pressing force.

  In addition, by adopting a configuration in which the ulna side of the wrist is opened at the portion between the plurality of band members, the biometric device does not float due to the ulnar protrusion, and accurate measurement by the sensor can be performed. .

  As described above, since the band main body is composed of a plurality of band members, the plurality of band members can be composed of members made of different materials. The side is made of a relatively hard material that does not slide against the skin, and the wrist side can be made relatively slippery against the skin, making it deformable with a relatively soft material to improve the fit. Can handle subtle shapes such as wrists, and can expand design variations by combining the colors of the materials.

Further, even when an individual band member is damaged or damaged, the band member of that part can be exchanged, which is convenient.
Moreover, the biometric apparatus of the present invention is characterized in that the plurality of band members are configured to be movable with respect to each other.

  By configuring in this way, even if the mounted part has a different shape and size depending on individual differences, and the movement of the band members can move and follow each other. The sensor, such as a sensor for measuring the pulse wave, does not float and is pressed against the wearing part with an appropriate pressing force, and the position is not shifted during exercise or training. Accurate measurements can be performed.

The biometric apparatus according to the present invention is characterized in that the pressing means is composed of a plurality of pressing means.

In addition, even on worn parts with different shapes and sizes due to individual differences, the sensor does not float, and the sensor such as a pulse wave measurement sensor is in close contact with the worn part and pressed with an appropriate pressing force. It is possible to carry out accurate measurement with a sensor without displacement during exercise, training, and the like.

The biometric apparatus according to the present invention is characterized in that the sensor includes a plurality of sensors.
In this way, if the sensor is composed of a plurality of sensors, the mounted part is supported by, for example, three or more points of the sensor and the pressing means, so that the wearing feeling is good, and Even if the wearing part is different in shape and size depending on individual differences, it does not float, but the sensor such as a pulse wave measurement sensor is in close contact with the wearing part and is pressed with an appropriate pressing force. Accurate measurement by the sensor can be performed without shifting the position during training or training.

  In addition, since the sensor is composed of a plurality of sensors, accurate measurement data can be obtained even if the same type of biometric data is provided if different types of sensors are provided. If provided, different types of biometric data can be measured at once.

  Further, the biometric device of the present invention is characterized in that the band and the measuring device main body are connected to the measuring device main body by a hinge that rotatably connects the band.

The band is rotated with respect to the measuring device main body with a constant urging force, regardless of the degree of opening, by the urging means, even for the mounted parts having different shapes and sizes depending on the movement. It will be.

  Therefore, the so-called damper effect does not cause a floating state, and a sensor such as a pulse wave measurement sensor is brought into close contact with the part to be attached and pressed with an appropriate constant pressing force by a constant urging force by the urging means.

It is characterized by combining with an urging means that increases the urging force at a predetermined ratio with respect to the opening amount with respect to the main body.

  Since it is only necessary to combine these two different urging means, the structure does not become complicated, the so-called damper effect does not cause a floating state, and a sensor such as a pulse wave measurement sensor is fixed by the urging means. Due to the urging force of the sensor, it is pressed against the part to be worn with an appropriate and constant pressing force.In addition, during exercise, training, etc. Measurements can be performed.

  Hereinafter, embodiments (examples) of the present invention will be described in more detail with reference to the drawings.

  FIG. 1A is a schematic side view of the biometric device of the present invention as viewed from the elbow side when worn on the left wrist of a living body, FIG. 2 is an end view of the biometric device of FIG. FIG. 4 is a perspective view of the living body measuring apparatus of FIG. 1A attached to the left wrist of the living body, FIG. 4 is a graph showing the opening size and pressing force of the hinge 26, and FIG. It is an end elevation similar to FIG. 2 of an Example.

In FIG. 1A-FIG. 3, the code | symbol 10 has shown the biometric apparatus of this invention on the whole.
Note that FIG. 1A shows a state where the wrist of the left hand is mounted so that the palm is on the upper side in FIG. 1A and the fingertip is located on the back side in FIG. 1A.

  The biometric device 10 includes a measurement device main body 14 having a shape curved along the outer shape of a wrist, which is a mounted portion of a living body. Further, on the wrist side of the measuring apparatus main body 14, there is provided a projecting portion 18 for height adjustment that extends along the longitudinal direction and projects slightly on the wrist side.

  Note that the measuring device main body 14 side is positioned on the palm side. However, it is of course possible to attach the measuring apparatus main body 14 side to the back side of the hand. In other words, it can be used upside down from FIG. 1A, that is, with the palm attached to the lower side.

  The material of the projecting portion 18 is not particularly limited. For example, a polyurethane resin, a polyvinyl chloride resin, or a polyethylene resin can be used to fit the wrist shape and improve the feeling of wearing. Polyolefin resins such as polypropylene resin, silicone resin, polyamide resin (nylon), polycarbonate resin, various synthetic resins such as polytetrafluoroethylene resin (fluororesin), nitrile elastomer, urethane rubber, fluororubber, NBR, acrylic rubber It is desirable to employ a flexible member having elasticity, such as various elastomers.

  Further, a sensor 20 is provided on the radial vein side of the projecting portion 18 so as to project slightly on the wrist side (note that the projecting amount is small, in FIG. 1A, In order to make the drawing easier to see, the sensor 20 and the protruding portion 18 are not expressed as protruding.) Information on the living body of the wrist from the sensor 20 is measured, and various arithmetic processes, display, and the like are performed by the arithmetic processing unit provided in the measurement apparatus main body 14.

  In this case, the sensor 20 for measuring biological information provided in the measurement apparatus main body 14 is not particularly limited. For example, the pulse wave measurement apparatus for measuring the pulse wave, the body temperature for measuring the body temperature, and the like. Desirably, the measuring device is a body temperature measuring device, at least one of the sweating measuring devices for measuring the degree of sweating, or a combination thereof, but is not limited to these measuring devices. It is also possible to mount a measuring device. This configuration is extremely convenient because it can cope with pulse wave measurement, body temperature measurement, and sweating degree measurement.

  Although not shown, the sensor 20 has a protective film made of, for example, a polyurethane resin, a polyester resin, a polystyrene resin, a silicon resin, or the like in order to prevent the sensor detection surface from being worn or damaged. Is preferably formed. In this case, the protective film can be formed on the sensor detection surface of the sensor 20 by, for example, adhesion, thermal welding, or painting.

  In addition, this protective film can be formed in the shape of a protective member so that it can be detachably attached to the detection surface of the sensor 20 so that it can be replaced with a new protective member in the event of wear damage or the like. Is very convenient.

  Further, the measurement apparatus main body 14 may have other functions such as a timekeeping function and a communication function (for example, a mobile phone function) in addition to mounting a sensor for measuring such biological information. .

  Further, as shown in FIGS. 1A to 3, a displacement prevention pad 22 is projected from an end portion 14 a on the ulna side of the measurement apparatus main body 14. In addition, in order to make this pad 22 for preventing slippage fit into the shape of the wrist and to improve the wearing feeling, various synthetic resins made of the same material as the protruding portion 18 described above, flexible having elasticity It is desirable to employ a member.

In addition, a concave portion 24 is formed in the vicinity of the end portion 14b on the rib side of the measuring apparatus main body 14 to accommodate the protruding portion of the rib portion of the wrist when it is attached to the wrist.
On the other hand, a band 28 having a curved shape along the outer shape of the wrist is connected to the end 14b on the rib side of the measuring apparatus main body 14 via a hinge 26 so as to be rotatable.

  As shown in FIG. 1A, the band 28 is formed such that the end portion 28b on the radius side is thick and the thickness is reduced toward the end portion 28a on the ulna side. When it is worn on the wrist, the pressure on the wrist is increased.

  In addition, the band 28 has various synthetic resins made of the same material as that of the protruding portion 18 and an elastic force in order to effectively apply a spring force and to fit the shape of the wrist to improve the wearing feeling. It is desirable to employ a flexible member having

In addition, similar effects can be obtained by adopting, for example, a shape memory alloy such as Ti—Ni instead of the band 28 made of a flexible member having elasticity.

By configuring the band 28 from a flexible member having an elastic force in this way, when the biometric device 10 is worn on the wrist, the end portion 28a on the ulna side of the band 28 and the measuring device main body 14 are arranged. It can be spread against the urging force directed inward in the direction in which the open ends between the end portions 14a on the ulna side approach each other, and can be easily attached to the wrist.

  When the biometric device 10 is worn on the wrist, the open ends between the ulna-side end portion 28a of the band 28 and the ulna-side end portion 14a of the measuring device main body 14 are inwardly approached. The state where the biometric device 10 is attached to the wrist can be stably maintained, and rotation, dropout, and the like of the biometric device 10 around the wrist can be effectively prevented. it can.

Although not shown, an elastic member such as a leaf spring can be interposed in the band 28, for example.
Further, as shown in the direction of arrow B in FIG. 1A by the hinge 26, the band 28 is rotated with respect to the measurement apparatus main body 14, so that, for example, when the wrist 28 is worn on the wrist, the ulna side of the wrist or It can be set as the structure which open | released the radius side, and can attach or detach a biometric apparatus to a wrist with what is called a touch from the ulna side of this wrist, or the open part 40 of the radius side.

  In addition, even in a worn part having a different shape and size depending on individual differences, and also with respect to its movement, it can follow by rotating the band 28 with respect to the measuring device main body 14 and does not float. A sensor 20 such as a pulse wave measurement sensor is in close contact with the part to be worn and is pressed with an appropriate pressing force, and the sensor 20 performs accurate measurement without being displaced during exercise or training. Can be done.

The hinge 26 is preferably provided with a biasing means (not shown) for biasing the band 28 in the direction of the measuring apparatus main body 14.
By providing the urging means in this way, the band 28 can be rotated with respect to the measuring apparatus main body 14 by the urging means even at the mounted part having a different shape and size depending on individual differences, and also for the movement. The sensor 20 such as a pulse wave measurement sensor is brought into close contact with the part to be attached and pressed with an appropriate constant pressing force by the urging force of the urging means, and can follow the movement by moving. In addition, accurate measurement by the sensor can be performed without shifting the position during exercise or training.

  Further, in this case, as shown in FIG. 4C, the urging means has a constant urging force up to a certain opening amount with respect to the opening amount of the band 28 with respect to the measuring device main body 14, and exceeds that amount. It is desirable that the biasing means is configured to increase the biasing force at a predetermined rate with respect to the opening amount.

  In this way, the biasing force is constant up to a certain opening amount with respect to the opening amount of the band 28 with respect to the measuring device main body 14, and the biasing force increases at a predetermined ratio with respect to the opening amount exceeding the opening amount. The band 28 is attached to the measuring device main body 14 with a constant urging force by the urging means, regardless of the degree of opening, even in the mounted parts having different shapes and sizes depending on individual differences. It will be rotated.

  Therefore, the sensor 20 such as a pulse wave measurement sensor does not float due to the so-called damper effect, and the sensor 20 is in close contact with the portion to be mounted and pressed with an appropriate constant pressing force by the constant biasing force by the biasing means. In addition, accurate measurement by the sensor can be performed without displacement during exercise, training, or the like.

  Furthermore, in this case, as shown in FIG. 4 (A), the urging means includes an urging means for reducing the urging force at a predetermined ratio with respect to the opening amount of the band with respect to the measuring apparatus body, and FIG. As shown in (2), it is desirable to combine with an urging means that increases the urging force at a predetermined ratio with respect to the opening amount of the band 28 with respect to the measuring device main body 14.

  Since it is only necessary to combine these two different urging means, the structure is not complicated, the so-called damper effect does not cause a floating state, and a sensor 20 such as a pulse wave measurement sensor is provided by the urging means. Due to the constant urging force, it is in close contact with the part to be worn and pressed with an appropriate constant pressing force.In addition, during exercise, training, etc., for example, resonance action does not occur, the position does not shift, and the sensor accurately Measurement can be performed.

  As an urging means having such a property as shown in FIG. 4A, for example, urging of a hinge structure as disclosed in JP-A-10-153214 and JP-A-10-252739 is employed. For example, a coil spring can be adopted as the biasing means having the properties shown in FIG. 4B.

  Moreover, as a hinge structure provided with an urging means having such a property as shown in FIG. 4C in combination with such an urging means, for example, JP-A-10-153214 and JP-A-10-252739 are disclosed. Can be employed, and is available, for example, from Strawberry Corporation.

  Further, as shown in FIG. 2, the band 28 has a shape in which two (two) parallel band members 30 are extended from both sides of the end portion 28 b on the rib side. They are connected to each other by the formed connecting portion 32.

  As a result, a substantially rectangular opening 34 is formed on the side of the end portion 28b on the rib side, thereby preventing stuffiness and reducing the weight when worn on the wrist. Yes.

  In addition, an open end 31 is formed at the end portion 28a on the ulna side, whereby it is possible to avoid the ulnar process, and the band member 30 is not floated by the ulna process. ing.

The open end 31 also functions as a positioning means for positioning so as to be positioned on the ulnar process when being worn on the wrist.
Therefore, since it functions as a positioning means when the biometric apparatus 10 is mounted on the living body mounting portion, the sensor 20 and a protruding pad 38 (described later) facing the sensor 20 with the living body mounting portion interposed therebetween are provided. For example, it can arrange | position to an exact position with respect to the radial vein which is a to-be-measured part of a to-be-attached site | part, and can perform the exact measurement by the sensor 20. FIG.

Furthermore, it is desirable that the end portions of these band members 30 in the short direction have a round-shaped cutout portion 30c so as not to hinder the movement of the wrist when worn on the wrist.
Thus, since the band 28 is composed of a plurality of strip members 30 in this embodiment, for example, the plurality of band members 30 can be composed of members of different materials, and its elasticity Due to the difference in the characteristics and frictional force, for example, the back side of the hand is made of a relatively hard material without slipping against the skin, the wrist side can be relatively slipped against the skin, and can be deformed with a relatively soft material With this configuration, it is possible to improve the fit and adapt to delicate shapes such as wrists, and to expand design variations by combining the colors of the materials.

  As shown in FIG. 5, the band member 30 can also be composed of three or more plural band members 30. FIG. 5 shows an embodiment in which three band members 30 are provided for convenience of explanation. However, this number is not limited, and although not shown, for example, two bands on each side. The number, the arrangement position, the length, and the like can be changed as appropriate, such as providing the members 30 or providing different numbers of band members 30 on both sides.

  Further, a pad portion 36 made of an elastic member is formed on the end portion 30a on the ulna side of each band member 30, and a pressing means that protrudes from the wrist side of the pad portion 36 on the wrist side. The projecting pad 38 is formed integrally.

  The material of the pad portion 36 should be a frictional force and elasticity in order to function as a pressing means, be painless, have a good wearing feeling, and prevent misalignment and dropout. For example, although not particularly limited, it is desirable to employ a flexible member having elasticity, such as various elastomers such as nitrile elastomer, urethane rubber, fluorine rubber, NBR, and acrylic rubber.

In addition, although the main-body part of the pad part 36 and the protruding pad 38 can be made of the same material, they can be formed of different materials.
By forming the protruding pad 38 as the pressing means from the band 28, that is, a part of the band member 30, the pressing means can be easily configured by injection molding or the like, resulting in a complicated configuration. The cost can also be reduced.

  By forming the protruding pad 38 as a pressing means from a part of the band in this manner, the sensor 20 and the protruding pad 38 of the band 28 facing the sensor 20 with the living body mounted portion interposed therebetween are covered. The attachment site is supported, and the sensor 20 is pressed against the measurement site of the living body with a constant pressing force, for example, by giving elasticity to the band 28 itself.

In addition, the main body portion of the pad portion 36 and the protruding pad 38 can be configured to be detachable.
Further, it is desirable that the pad portion 36 is configured to be detachable with respect to the main body portion of the band 28, so that depending on the individual, the size and shape of the wrist, particularly the size of the ulnar process, The band 28 can be exchanged, the design variation can be expanded, and it can be exchanged when the pad portion 36 is worn and damaged.

  Further, it is desirable that the band 28 itself is also configured to be detachable with respect to the measuring apparatus main body 14 via the hinge 26, so that the wrist, which is different in size and shape depending on individual differences, particularly the size of the ulnar process. Accordingly, the measurement device main body 14 can be exchanged, the design variation can be expanded, and the measurement can be exchanged when the pad portion 36 is worn and damaged.

  The biometric device 10 configured as described above is configured to resist the urging means of the band 28 with respect to the measurement device main body 14 via the hinge 26 in order to be worn on the wrist that is a worn portion of the living body. Open the wrist and insert the wrist from the open end formed between the ulna side end 28a of the band 28 and the ulna side end 14a of the measuring device body 14 from the rib side of the wrist. Just do it.

  By mounting in this way, the biometric device 10 of the present invention is provided when the protruding pad 38 of the pad portion 36 and the sensor 20 are mounted on the wrist as shown in FIG. 1A. The sensor 20 is pressed against the radial vein, which is the measurement site of the living body, as indicated by the arrow C because it is provided on the opposite side of the wrist, which is the mounting portion of the living body.

  Therefore, the wrist which is the attachment site is supported by such a sensor 20 and the protruding pad 38 which is a pressing means facing the sensor 20 with the attachment portion of the living body interposed therebetween, and the sensor 20 is the measurement portion of the living body. Because it is pressed against the radial vein, the feeling of wearing is good, and even in the worn part with different shape and size due to individual differences, it does not float and the sensor 20 such as a sensor for measuring pulse waves, It is possible to carry out accurate measurement with a sensor without being displaced during exercise, training, or the like while being in close contact with the part to be worn and being pressed with an appropriate pressing force.

  In addition, since it is only necessary to provide such a sensor 20 and a protruding pad 38 that is a pressing means that faces the sensor 20 across a wrist that is a worn portion of a living body, the other portions are appropriately opened. Therefore, for example, even when the wrist is attached to the wrist, the structure can be such that the ulna side or the radius side of the wrist is opened. Can be attached to and detached from the wrist with a so-called one-touch operation.

In addition, by adopting a configuration in which the ulna side of the wrist is opened, the biometric device 10 is not lifted by the ulnar process, and accurate measurement by the sensor 20 can be performed.
In addition, since the sensor 20 and the protruding pad 38 that is a pressing means facing the sensor 20 across the mounting portion of the living body are supported by the mounting portion, the mounting portion, for example, The rotation of the biometric device 10 around the wrist can be prevented, and accurate measurement by the sensor 20 can be performed without shifting the position during exercise or training.

  In addition, since the sensor 20 and the protruding pad 38 that is a pressing means facing the sensor 20 with the wearing part of the living body sandwiched between the sensor 20 and the wearing part, the wearing part is supported. Also, the fit is good, even when the wrist is thick, there is no pain and there is no risk of obstructing exercise or training.

Although not shown in the drawings, a concavo-convex portion may be formed on the wrist-side surface of a member that contacts the wrist, such as the height adjusting protrusion 18, the displacement prevention pad 22, and the protrusion pad 38.
By forming the concavo-convex portion in this way, a frictional force is generated between the concavo-convex portion and the wrist, thereby effectively preventing rotation, dropout, and the like of the biometric device 10 around the wrist. it can. In addition, moisture such as sweat due to the sweating action of the wrist can be evaporated through the gaps and grooves formed by the concave and convex portions at the time of wearing, and a reduction in wearing feeling due to stickiness due to sweat or the like can be prevented.

  In this case, the concavo-convex portion is partially formed even if it is formed over the entire wrist-side surface of a member that contacts the wrist, such as the height adjusting protruding portion 18, the displacement preventing pad 22, and the protruding pad 38. You may do it. In addition, the shape of the concavo-convex portion can be changed as appropriate, such as a minute concavo-convex shape, a groove shape, a columnar shape (columnar shape, prismatic shape), a dome shape, or a combination thereof.

Although not specifically described, the formation of the concavo-convex portion can be similarly applied to the following embodiments.
Further, in this embodiment, the sensor 20 is provided with one sensor on the radial vein side. However, although not shown, the sensor 20 may be composed of a plurality of sensors.

  In this way, if the sensor 20 is composed of a plurality of sensors 20, it is supported on the wrist that is the attachment site, for example, at three or more points of the sensor 20 and the protruding pad 38 that is the pressing means. Will be.

  Therefore, the wearing feeling is also good, and even the wearing parts of different shapes and sizes due to individual differences do not float, and the sensor 20 such as a pulse wave measurement sensor is in close contact with the wearing part and is moderate. Accurate measurement by the sensor 20 can be performed without being displaced during exercise, training, or the like.

  In addition, since the sensor 20 is composed of a plurality of sensors, if a plurality of sensors of the same type are provided, accurate measurement data can be obtained even with the same type of biometric data, and different types of sensors can be obtained. If it is provided, different types of biometric data can be measured at once.

In this case, the size, shape, arrangement position, etc. of the plurality of sensors can be changed as appropriate.
In this embodiment, the sensor 20 is provided on the radial vein side on the palm side, but the sensor 20 may be provided on the radial side on the back side of the hand or on the ulna side. It is also possible.

  In the embodiment of FIG. 1A, the position of the pad portion 36 formed on the ulna end 28a of the band 28 is substantially the same as the position of the ulna end 14a of the measuring device main body 14. The length of the band 28 is set.

  However, as shown in FIG. 1B, the position of the pad portion 36 formed on the ulnar side end portion 28 a of the band 28 is positioned at a position shorter than the position of the ulnar side end portion 14 a of the measuring device main body 14. Thus, the length of the band 28 can be set short.

  In this case, as indicated by the arrow in FIG. 1B, at least the positions of the sensor 20, the projecting pad 38, and the displacement prevention pad 22 form a substantially triangular shape with respect to the attachment site. Thus, a uniform pressing force is applied.

  Accordingly, the sensor 20 is supported at three or more points of the projecting pad 38 that is the pressing means and the displacement preventing pad 22, so that the wearing feeling is good, and the shape and size vary depending on individual differences. Even when the wearing part is different, the sensor 20 such as a pulse wave measurement sensor is not in a floating state and is pressed against the wearing part with an appropriate pressing force, and is also positioned during exercise, training, etc. Accurate measurement by the sensor 20 can be performed without shifting.
