  One embodiment of the present invention is an electrode unit. The electrode unit is an electrode capable of detecting a biological signal emitted from the measured object, a penetrating portion that penetrates clothing worn by the measured object, and a first surface of the clothing that is in contact with the skin of the measured object. A fixing portion that is disposed on a different second surface and that detachably fixes the electrode to the clothing by interposing the clothing with the electrode via the penetrating portion. The electrode or the fixed portion is configured to be connectable to a cable that sends a biological signal detected by the electrode to the biological signal measuring device.

  The object to be measured is, for example, a human body or an animal. The biological signal emitted from the measured object is, for example, a heartbeat, brain wave, pulse, respiration, and the like. The shape of the electrode unit is, for example, a pin badge type or a safety pin type. The pin badge includes a badge portion including a pin and a fastening portion having an insertion hole for the pin. The safety pin is a U-shaped pin having a sharp end formed at one end and a retaining portion for accommodating the other end. When the electrode unit is of a pin badge type and the badge portion is provided with an electrode, for example, the penetrating portion corresponds to a pin included in the badge portion, and the fixing portion corresponds to a fastening portion having a pin insertion hole. When the electrode unit is of a pin badge type and an electrode is provided on the fastening portion, for example, the penetrating portion corresponds to a pin included in the badge portion, and the fixing portion corresponds to a main body portion connecting the pins of the badge portion. . When the electrode unit is a safety pin type, for example, the electrode is connected to the side where the fastening portion is installed, a portion having one end formed sharply corresponds to the through portion, and the fastening portion corresponds to the fixing portion. I do.

  According to one aspect of the present invention, the electrode unit is detachably fixed to the clothes, so that the degree of freedom of the arrangement of the electrode unit is improved. Further, the electrode unit is fixed to the clothes by the penetrating portion penetrating the clothing, and the electrode and the fixing portion sandwiching the clothing through the penetrating portion. Therefore, it is possible to prevent the electrode unit installed on the clothes from coming off the clothes. Thus, it is possible to prevent the activity of the measured object from being limited by mounting the electrode unit.

  In one aspect of the present invention, the penetrating portion and the fixing portion may be conductive, and the fixing portion may be configured to be connectable to a cable. As a result, the cable is connected to the outside of the clothes, so that the cable does not come into contact with the skin of the measured object, and discomfort caused by the cable being in contact with the skin of the measured object can be reduced.

Further, when the penetrating portion and the fixing portion are conductive and the fixing portion is configured to be connectable to a cable, the fixing portion has a shape to which a conductive terminal provided at the end of the cable can be connected. Good. For example, the fixing portion may be formed so as to have a shape in which the terminal of the cable can be fitted. Specifically, when the terminal of the cable has the concave shape of the snap button, the fixing portion is formed to have the convex shape of the snap button. Further, for example, when the terminal of the cable has a shape having a pair of gripping members, the fixing portion is formed to have a shape that can be gripped by the pair of gripping members. The shape having a pair of gripping members is, for example, a shape of a clip that can pinch the fixing portion by a force of a spring or the like.

  When the fixing portion has a shape that allows connection of a conductive terminal provided at the end of the cable, the cable and the electrode unit can be separated from each other. When the clothes are attached and detached while being attached, by removing the cable, the cable can be prevented from hindering the operation.

  In one embodiment of the present invention, the electrode may have a shape connectable to a first electrode provided in contact with the skin of the measured object. For example, when the first electrode has the convex shape of the snap button, the electrode of the electrode unit is formed in the concave shape of the snap button. By connecting the electrode of the electrode unit to the first electrode installed on the skin of the object to be measured, the electrode of the electrode unit is hardly displaced from the installation position of the object to be measured, and the biological signal can be stably measured. Can be.

  In one aspect of the present invention, the electrode unit includes an electrode capable of detecting a biological signal emitted from the measured object, a penetration portion penetrating clothes worn by the measured object, and a measured object of the clothes. A fixing portion that is disposed on a second surface different from the first surface that is in contact with the skin of the subject, and that fixes the electrode to the clothing by sandwiching the electrode and the clothing through the penetrating portion; A wireless communication unit that transmits a signal to the biological signal measuring device. As a result, a cable for connection to the biological signal measuring device is not connected to the electrode unit, and thus, operations such as attachment to clothes and attachment / detachment of clothes with the electrode unit attached are facilitated.

  Another aspect of the present invention is a garment having a cable capable of connecting any one of the plurality of electrode units described above and a biological signal measuring device. In the clothing, the cable is wired and fixed so that a plurality of electrode units can be installed at predetermined positions on the measured object. Thereby, for example, since the rough arrangement of the electrode units is indicated or the wiring of the cable is not required, the measurement of the biological signal can be performed more easily. Further, since the cable is fixed to the clothes, it is possible to prevent the operation from being hindered by the cable.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The configuration of the following embodiment is an exemplification, and the present invention is not limited to the configuration of the embodiment. In addition, the drawings are schematic, and hatching is omitted even in a portion showing a cross section.

<First embodiment>

The electrode unit 1A according to the first embodiment has a so-called pin badge shape, and is detachably attached to clothing of a measured object. The electrode unit 1A includes a badge part 11A and a fastening part 12A.

  The badge portion 11A includes an electrode 111 and a pin 112. The electrode 111 and the pin 112 are each formed of a conductive member. The conductive member is, for example, a metal, a member plated with metal, or the like. The metal used for the electrode 111 and the pin 112 is not limited to a specific metal.

The surface of the electrode 111 that comes into contact with the skin of the measured object has a substantially flat plate shape in order to ensure contact with the skin of the measured object. However, the present invention is not limited to this, and a plurality of protrusions may be provided on the surface of the electrode 111 that contacts the skin of the measured object in order to further ensure contact with the skin of the measured object. The pin 112 is provided on the surface of the electrode 111 opposite to the surface in contact with the skin of the measured object. The pin 112 is installed substantially perpendicular to the electrode 111. In addition, the electrode 111 and the pin 112 may be integrally formed, or may be separate members. The pin 112 has a shape capable of penetrating the clothes worn by the measured object.

  The fastening portion 12A has an insertion hole 121 for the pin 112. When the pin 112 is inserted into the insertion hole 121, the pin 112 is gripped by the retaining portion 12A. The fastening portion 12A is formed of a conductive member. The conductive member is, for example, a metal, a member plated with metal, or the like. The metal used for the fastening portion 12A is not limited to a specific metal. The cable 2 connected to the electrocardiograph is connected to the fastening portion 12A. Note that the fastening portion 12A only needs to be conductive at least in a portion that is in contact with the pin 112 of the insertion hole 121 and to which the cable 2 is connected.

  The badge portion 11A is located inside the garment, the pin 112 penetrates the garment, and the pin 112 is inserted into the insertion hole 121 of the fastening portion 12A on the outside of the garment, whereby the fastening portion 12A grips the pin, Electrode unit 1A is fixed to clothes. As a result, the electrode unit 1A is detachably fixed to the clothes.

  When the electrode unit 1A is attached to clothes as described above, the electrodes 111 come into contact with the skin of the measurement target wearing the clothes. Therefore, the biological signal emitted from the measured object can be detected by the electrode 111. The biological signal detected by the electrode 111 is transmitted from the electrode 111 to the pin 112, from the pin 112 to the fastening portion 12A, from the fastening portion 12A to the cable 2, and is transmitted over the cable 2 to be input to the electrocardiograph. Is done.

<Operation and Effect of First Embodiment>
In a use case of the electrode unit 1A, for example, a doctor may manage the state of a patient based on a biological signal of the patient. In this case, for example, a doctor attaches the electrode unit 1A to the patient's clothes at the hospital. At this time, by marking the attachment position of the electrode unit 1A on the clothes, even if the electrode unit 1A is removed, the patient himself can attach the electrode unit 1 to the same position again. The marking of the mounting position of the electrode unit 1A may be performed, for example, by leaving a hole formed by the pin 112 at the mounting position, or may be performed by coloring clothes.

  When the measurement of the biological signal is interrupted, the patient may take off his or her clothes with the electrode unit 1A attached. When restarting the measurement of the biological signal, the patient only needs to wear the clothes on which the electrode unit 1A is installed again.

  When an attempt is made to detect a biological signal emitted from an object to be measured by an electrode, an appropriate mounting position of the electrode on the object to be measured differs for each individual. Here, as described above, in the first embodiment, the electrode unit 1A is of a pin badge type, and is detachably fixed to clothing. Therefore, the degree of freedom in arranging the electrode unit 1A with respect to clothing is high. Therefore, according to the electrode unit 1A, it is possible to install the electrode at an appropriate position according to the individual of the object to be measured wearing clothes. Further, the installation position can be easily changed. Further, since the clothes on which the electrode unit 1A is installed are not limited to predetermined clothes, it is not necessary to create a dedicated clothes for installing the electrodes. Further, the electrode unit 1A can be worn on any clothes owned by the subject. Thus, it is possible to reduce the cost when measuring the biological signal using the electrode unit 1A.

  In addition, since the pin badge-type electrode unit 1A is fixed to clothes, the object to be measured can lead a daily life while wearing the electrode unit 1A. In addition, since the pin badge-type electrode unit 1A sandwiches the clothes, the pin badge-type electrode unit is unlikely to be displaced from the attached position, and is less likely to be detached from the clothes. Also, by inserting and removing the pin 112 from the insertion hole 121 of the fastening portion 12A, the electrode unit 1A can be attached to and detached from clothes, so that attachment and detachment are easy.

  Further, in the first embodiment, the cable 2 is connected to the fastening portion 12A, but the cable 2 may be connected to the electrode 111. When the cable 2 is connected to the electrode 111, the fastening portion 12A may be formed of a non-conductive material.

  In addition, since the electrode unit 1A is attached to clothes, for example, it may be difficult to ensure the contact between the electrode 111 of the electrode unit 1A and the skin of the measured object due to the operation of the measured object. Therefore, as a method of further increasing the contact between the electrode 111 of the electrode unit 1A and the skin of the measured object, for example, the following method is available.

  FIG. 2 is a diagram illustrating an example of a method for further increasing the contact between the electrode 111 and the skin of the measured object. In FIG. 2, the badge portion 11A is covered with an adhesive tape 50, and the tape 50 is attached to the skin of the measured object, so that the contact between the electrode 111 and the skin of the measured object is enhanced. . The tape 50 is, for example, a nonwoven fabric, a foam tape, or the like.

  FIG. 3 is a diagram illustrating an example of a method for further increasing the contact between the electrode 111 and the skin of the measured object. In FIG. 3, the electrode unit 1 </ b> A is fixed from the outside by attaching the belt 60 from above clothing on which a plurality of electrode units 1 </ b> A are attached. Thereby, the contact between the electrode 111 and the skin of the measured object is enhanced.

  FIG. 4 is a diagram illustrating an example of a method for increasing the contact between the electrode 111 and the skin of the measured object. In FIG. 4, a depression is formed inside the contact surface of the electrode 111 with the skin to be measured so that a space 70 is formed between the skin and the electrode 111. By increasing the air pressure in the space 70, the contact between the electrode 111 and the measured object is ensured. As a method of increasing the air pressure in the space 70, for example, a suction cup is formed of silicon or the like around the electrode 111, or a tube (a fruit) connected to the space 70 is attached to the electrode 111, There are ways to deflate.

  Further, as a method of further increasing the contact between the electrode 111 and the skin of the measured object, there is a method of using clothing that makes tight contact with the subject, in addition to the above-described method.

<Second embodiment>
In the second embodiment, the cable is not directly connected to the fixing portion of the electrode unit, but the cable has a terminal at the tip, and the fixing portion of the electrode unit is configured to be connectable to the terminal. You. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 5 is a diagram illustrating an example of a schematic configuration of an electrode unit 1B according to the second embodiment. In the second embodiment, the electrode unit 1B is of a pin badge type, and has a badge portion 11A and a fastening portion 12B. A terminal 21 is provided at the end of the cable 2. The terminal 21 is formed of, for example, a conductive material.

The retaining portion 12B has a pin insertion hole as in the first embodiment. The fastening portion 12 </ b> B has a shape to which a terminal 21 provided at the tip of the cable 2 can be connected. In the example shown in FIG. 5, the terminal 21 provided at the tip of the cable 2 and the fastening portion 12B of the electrode unit 1B form a snap button. In the example shown in FIG. 5, the terminal 21 provided at the tip of the cable 2 is formed in a concave shape of a snap button, and the fastening portion 12B of the electrode unit 1B is formed in a convex shape of the snap button. . By fitting the concave terminal 21 to the convex fastening portion 12B, the fastening portion 12B and the cable 2 are connected, and as a result, the cable 2 is connected to the electrode 111. Thereby, the biological signal detected by the electrode 111 can be transmitted to the cable 2. Note that the terminal 21 may be formed in a convex shape, and the fastening portion 12B may be formed in a concave shape.

  FIG. 6 is a diagram illustrating another example of the shape of the retaining portion of the electrode unit 1B according to the second embodiment. In the example shown in FIG. 6, the terminal 21B provided at the tip of the cable 2 is formed in a clip shape. Specifically, the terminal 21B is formed of a pair of conductive members, and is formed so that a predetermined object can be gripped by the pair of members. The fastening portion 12C of the electrode unit 1B has a main body 123 and a sandwiched portion 122 sandwiched between the clip-shaped terminals 21B. The pinched portion 122 has a U-shape, for example, so as to be easily pinched by the clip-shaped terminal 21B. Since both the clip-shaped terminal 21B and the fastening portion 12C are formed of a conductive material, the clip-shaped terminal 21 sandwiches the sandwiched portion 122 of the fastening portion 12C, thereby connecting the fastening portion 12C and the cable 2. Thus, the cable 2 is connected to the electrode 111. Thereby, the biological signal detected by the electrode 111 can be transmitted from the pinched portion 122 to the cable 2 through the terminal 21B.

  According to the second embodiment, the electrode unit 1B does not directly connect the cable 2, and the fastening portions 12B and 12C have shapes that match the shapes of the terminals 21 and 21B provided at the end of the cable 2. Thereby, for example, the existing cable 2 having the terminals 21 and 21B at the distal end can be used.

  In addition, since the electrode unit 1B and the cable 2 are separated, for example, by removing the terminals 21 and 21B from the fastening portions 12B and 12C, it becomes easy to attach and detach clothes while the electrode unit 1B is attached.

  Further, the cable 2 can be connected to the electrode unit 1B after the mounting position of the electrode unit 1B is determined and the electrode unit 1B is mounted on clothes. Further, after removing the cable 2 from the electrode unit 1B, the electrode unit 1B can be removed from the clothes. This makes it easier to attach and detach the electrode unit 1B to and from clothing.

In the example shown in FIG. 7, the electrode 8 attached to the measured object is formed in a convex shape, and the electrode 111B is formed in a concave shape into which the convex portion of the electrode 8 can be fitted. By fitting the concave electrode 111B to the convex electrode 8, the electrode 8 and the electrode 111B are connected. Thereby, the biological signal detected by the electrode 8 is transmitted to the electrode 111B, the pin 112, the fastening portion 12A, and the cable 2. Note that the electrode 8 may be formed in a concave shape, and the electrode 111B may be formed in a convex shape.

  According to the third embodiment, when there is an existing electrode attached to the measured object, the existing electrode can be used. Further, since the electrode unit 1C is connected to the electrode 8 attached to the measured object, the electrode unit 1C is hardly detached from the electrode 8, and the biological signal of the measured object can be stably measured.

  In addition, by attaching the electrode 8 to the measured object first and then attaching the clothes and the electrode unit 1C to the measured object, the positioning accuracy of the electrode 8 and the electrode unit 1C is improved.

The potential detection unit 102 may generate a synchronization signal for synchronizing the biological signal with another electrode unit 1 and transmit the generated synchronization signal to the communication terminal 4 together with the biological signal.

  The communication terminal 4 includes a control unit 41, a storage unit 42, a first wireless communication unit 43, and a second wireless communication unit 44. The biological signal transmitted from each electrode unit 1 is received by the second wireless communication unit 44 and output to the control unit 41. The control unit 41 realizes the function of the electrocardiogram generation unit 411 by executing an application of the biological signal measurement system. The electrocardiogram generation unit 411 generates electrocardiogram data from the biological signal from each electrode unit 1 input from the second wireless communication unit 44. At this time, when a synchronization signal is received together with the biological signal from each electrode unit 1, the electrocardiogram generation unit 411 synchronizes the biological signal from each electrode unit 1 using the synchronization signal, and outputs the electrocardiogram data.

  According to the sixth embodiment, by providing the electrode unit 1 with the wireless communication function, the connection between the electrode unit 1 and the cable 2 is eliminated, so that the attachment and detachment of the electrode unit 1 to and from clothing can be made lighter by the amount of the cable 2. Or move easily when attached to clothing.

<Seventh embodiment>
In the seventh embodiment, the cable 2 is previously wired and installed on clothes according to the arrangement of the electrode unit 1. The method of installing the cable 2 on the clothes is, for example, a method of sewing the cable 2 on the clothes, sewing a conductive material on the clothes according to the wiring of the cable 2, and using the wiring of the conductive material as the cable 2. There is a way. In the case of the method of sewing the cable 2 to the garment, for example, by sewing the cable 2 on the lining of the garment, the presence of the cable 2 can be hidden from the appearance. In the case of using a wiring made of a conductive material as the cable 2, the pin 112 of the electrode unit 1 is made to penetrate the wiring of the conductive material on the clothes so that the conductive material can be used as a living body. A signal is transmitted. However, in this case, the surface where the conductive material is wired is covered with a non-conductive material.

  FIG. 13 is a diagram illustrating an example of clothes in which a cable has been installed. The cable 2 that connects the plurality of electrode units 1 is installed on the garment 6 by any of the methods described above. As the electrode unit 1, any of the electrode units 1A, 1B, 1C, and 1D of the first to fourth embodiments may be used. When the electrode units 1B and 1D are used, the cable 2 (clothing 6) and the electrode units 1B and 1D can be separated.

  The other end of the cable 2 connecting each electrode unit 1 is connected to an electrocardiograph 3. The electrocardiograph 3 may be attached to the clothing 6, or may be put in a pocket of clothing (for example, pants or the like) different from the clothing 6 worn by the measurement subject, or may be attached to the clothing 6. May be fixed to another belt or the like.

  When the cable 2 is sewn into clothes, for example, it is attached so that the tip to which the electrode unit 1 is connected has a predetermined movable range. Thereby, the mounting position of the electrode unit 1 can be adjusted according to the measured object.

  When a cable is connected between the electrode units 1, the cable may be installed on the clothes 6. For example, when the electrode unit 1 having the wireless communication function as in the sixth embodiment is adopted, the electrode units 1 may be connected by a cable in order to synchronize the electrode units 1.

  According to the seventh embodiment, since the cable 2 is previously installed on the clothing, the clothing is worn, the electrode unit 1 is connected to the end of the cable 2, and the electrode unit 1 is attached to the clothing. Can be easily measured. In addition, since the cable 2 is fixed to the clothes, it is possible to suppress the operation being restricted by the cable 2 during the activity.

  In the seventh embodiment, it has been described that the cable connected to the electrode unit 1 is installed on clothes. The present invention is not limited to this. For example, a plurality of electrode units 1 having a wireless communication function according to the sixth embodiment, which do not need to be connected by a cable between the electrode units 1, may be used for measuring a biological signal. The clothing may be pre-installed at the attachment position (for example, FIG. 13 and the like). In addition, even when the electrode unit 1 according to any of the embodiments is adopted, a mark of a mounting position of the electrode unit 1 may be provided on clothes.

<Others>
In the above embodiment, a human body is assumed as the measured object. However, the measured object is not limited to a human body, and may be, for example, an animal such as a dog or a cat. When the object to be measured is a small animal, not all the electrodes used for measurement need to be the electrode unit 1, some of the electrodes are attached to the extremities of the animal to be measured, and the other electrodes are clothing. May be attached to the moving body of the animal together with the clothes.

  The plurality of electrode units may not be connected by the cable 2 but may be connected by wireless communication. Thereby, it can be suppressed that the operation is restricted by the cable 2 during the activity.
