As a technique for measuring this myoelectric potential, a technique of capturing myoelectric potential transmitted from the muscle to the skin surface through the body tissue, which is a conductor, is widely used by an electrode attached to the surface of the body. In particular, in the case of a forearm prosthesis, the myoelectric potential of 2 channels (hereinafter referred to as 2ch) was measured by an electrode in contact with the skin surface on the extensor group and the flexor group remaining at the stump and measured on the flexor side. The structure is such that when the strength of the myoelectric potential exceeds the threshold value, the hand is closed, and conversely, when the strength of the myoelectric potential on the extensor side exceeds the threshold value, the hand is opened.

  As an electrode device for measuring myoelectric potential by integrating such a plurality of electrodes, for example, Patent Document 1 discloses a central portion on one side of a rectangular plate (for example, a flat ceramic substrate) as an electrode support member. A myoelectric potential in which two detection electrodes are attached at a predetermined interval in the vicinity, and an annular ground electrode (reference electrode) is provided on the outer peripheral edge of one side of the plate so as to surround the two detection electrodes. Measuring electrodes have been proposed. And as said each electrode, there exists description of the structure which plated the surface of the flexible material, and the structure which formed each electrode as a conductive pattern in the flexible substrate.

Further, in Patent Document 2, a predetermined number of ground electrodes are arranged on the surface of a sheet-like electrode support member (preferably a towel cloth) having flexibility to follow the body surface, and the installation is performed. A plurality of rows of first detection electrodes and second detection electrodes arranged in parallel at equal intervals are provided on both sides of the row of electrodes, and the first detection electrodes and the second detection electrodes arranged as described above are provided on the respective sides. A myoelectric potential measuring electrode device has been proposed in which each electrode row is configured to conduct in series with an external connection wiring.
The structure shown in FIG. 11 is configured such that a myoelectric potential measuring electrode device is attached to the inside of a belt such as a towel cloth, and each electrode is exposed to the inner surface.

Furthermore, high-speed data transmission at a high frequency is possible.

  Since all the conductive fibers have an extremely small diameter, they can be woven into a woven fabric to form a textile. Since the conductive fiber does not take up space in the textile, the original texture of the textile such as flexibility can be maintained.

  Further, when the wiring is an optical fiber, crosstalk between the wirings does not occur, so that the wirings can be closely woven so as to be adjacent to each other in the textile. Since the wiring comprised of the optical fiber is excellent in light weight, the burden on the wearer when it is densely woven into the textile can be reduced. Furthermore, the wiring constituted by the optical fiber is excellent in durability because it hardly corrodes even when it is exposed to moisture by the sweat of the wearer.

There is no particular restriction. For example, it is preferable from a viewpoint of wearability that it is the cylindrical shape which covers the mounted artificial hand. More specifically, as illustrated in FIG. 3, there is a cylindrical arm cover 10 that covers a prosthetic hand portion that is attached to the forearm portion 5.
The myoelectric potential measuring artificial hand arm cover of the present invention may have a shape integrated with a sleeve portion of clothing.

  FIG. 1 is an example in which the detection electrode unit 3 is arranged to extend outside the textile 1, and FIG. 2 is an example in which the detection electrode unit 3 is installed in the textile 1. The detection electrode unit 3 may be disposed outside the textile 1 or may be disposed therein.

  As the detection electrode unit 3, a known one that can measure the myoelectric potential of the wearer's arm can be used. For example, there is known a technique in which myoelectric potential is measured by making contact with the skin surface on the extensor group and the flexor group remaining at the stump of the arm on which the prosthetic hand is worn.

  The method for holding the detection electrode unit 3 in contact with the skin surface is not particularly limited. For example, the detection electrode unit 3 is bonded to the skin surface via an adhesive containing an electrolyte, or the detection electrode unit 3 is used with an adhesive tape. Is attached to the skin surface, the detection electrode unit 3 is pressed against the skin surface with a rubber band, and the forearm portion 5 to which the arm cover 10 is attached is shaped to fit the gap between the arm cover 10 and the forearm portion 5. And a method of disposing the detection electrode unit 3 in the above.

  The wiring 2 transmits a signal input / output to / from the detection electrode unit 3, and for example, a conductive fiber (conductive wiring) that transmits an electric signal, an optical fiber that transmits an optical signal, or the like can be used.

  In FIG. 3, the connector 4 is connected to control the motor 6. A change in the myoelectric potential of the forearm portion 5 is detected (measured) by the detection electrode unit 3, and a signal conveying the change is transmitted to the connector 4 by the wiring 2. In the connector 4, the built-in signal processing IC processes the signal and further controls the motor 6 to drive the hand portion 7 of the artificial hand. That is, the wearer of the arm cover 10 of the present invention can operate the artificial hand at will by moving the muscles of his / her arm.

  The connector 4 may be separately connected to an external device for processing the input / output signals and an external device for controlling the movement of the motor 6 and the artificial hand. Examples of the connection means include telecommunications, optical communication, and wireless communication.

  1 and 2 are schematic development views of the arm cover 10. The detection electrode portions 3 are respectively connected to one end sides of the plurality of wirings 2, and the other end sides of the respective wirings 2 are collectively connected to one connector 4. Each wiring 2 is woven and arranged in the textile 1.

  Signals output from each detection electrode unit 3 are collected by the connector 4 via each wiring 2. Conversely, a signal input to the connector 4 is input to each detection electrode unit 3 via each wiring 2. That is, signals input to and output from each detection electrode unit 3 in the connector 4 can be processed together.

  FIG. 1 is an example in which the detection electrode unit 3 and the connector 4 are arranged to extend outside the textile 1, and FIG. 2 is an example in which the detection electrode unit 3 and the connector 4 are arranged in the textile 1. The detection electrode unit 3 and the connector 4 may be disposed outside the textile 1 or may be disposed therein.

As shown in FIGS. 1 and 2, the arm cover 10 of the present invention has the flexibility to follow the movement of the forearm portion 5 and the prosthetic hand 7 because the wiring 2 is woven into the textile 1. Even when the movement is intense, the wiring 2 is not likely to be detached from the textile 1.
Although not shown in FIGS. 1 to 3, the arm cover 10 is provided with a chuck (zipper), a button, an elastic rubber band, a string, etc. in order to have the same wearability as that of general clothing. May be.

  As shown in FIGS. 1 to 3, the arm cover 10 of the present invention preferably includes a plurality of wires 2 in the textile 1. It becomes easy to arrange the plurality of detection electrode portions 3 at desired positions of the arm cover 10.

As shown in FIGS. 1 to 3, the arm cover 10 of the present invention is preferably provided with at least one connector 4 connected to the wiring 2. A signal transmitted from the detection electrode unit 3 through the wiring 2 can be further transmitted to an external device such as a motor 6 through the connector 4.
The number of connectors provided on the arm cover 10 may be one connector 4 as shown in FIGS. 1 to 3, or two or more connectors 8 as shown in FIGS. 4 and 5. It may be provided.

  FIG. 4 is an example in which the detection electrode unit 3 and the connector 8 are arranged to extend outside the textile 1, and FIG. 5 is an example in which the detection electrode unit 3 and the connector 8 are arranged in the textile 1. The detection electrode unit 3 and the connector 8 may be disposed outside the textile 1 or may be disposed therein.

  In the arm cover 10 shown in FIGS. 1 and 2, the wiring 2 has a bent portion 9. Here, the bent portion 9 refers to a portion in the wiring 2 where a portion along the warp of the textile 1 and a portion along the weft of the textile 1 are switched. By having the bent portion 9, the wiring 2 whose direction is changed at a desired position in the textile 1 can be disposed. This means that the detection electrode unit 3 can be arranged at a desired position in the textile 1.

In FIGS. 1 and 2, the bent portion 9 is arranged so as to be bent at a right angle, but it does not necessarily have to be a right angle. The wiring 2 constituting the bent portion 9 may be arranged so as to draw a gentler curve (not shown) without being arranged at a right angle.
If the bent portion 9 in which the wiring 2 is switched from the warp to the weft of the textile 1 has a gentler curve than a right angle, the mechanical stress applied to the bent portion 9 is reduced, and the wiring 2 may be torn. Since it decreases, it is preferable.

  In the arm cover 10 of the present invention, the wiring 2 is preferably a conductive fiber (conductive wiring) or an optical fiber.

  When the wiring 2 is a conductive fiber, even when the wiring 2 is exposed to ultraviolet rays such as sunlight, it is difficult to be decomposed, so that the durability is excellent. Further, even when mechanical stress is generated in the bent portion 9, the wiring 2 made of conductive fibers is preferable because it can endure without tearing.

  As the conductive fiber that can be used as the wiring 2, for example, a metal fiber 11 made of copper (Cu) or a copper alloy as shown in FIG. 6 can be used. The metal fiber 11 is preferably provided with a coating layer 13 made of titanium (Ti) or titanium oxide so as to cover the outer periphery of the metal wire 12. By providing the covering layer 13, the metal wire 12 can be protected from oxidation and corrosion.

  The thickness (diameter) of the metal wire 12 is preferably 10 to 100 μm. When it is equal to or higher than the lower limit value of this range, the metal fiber 11 can have an appropriate rigidity for weaving the textile 1, and when it is equal to or lower than the upper limit value of this range, the metal fiber 11 is woven into the textile 1. Can be provided with the appropriate flexibility required. That is, from the viewpoint of giving the metal wire 12 flexibility, the metal wire 12 is preferably as thin as possible. From the viewpoint of providing rigidity to the metal wire 12, the metal wire 12 is preferably as thick as possible. What is necessary is just to set the thickness of the metal wire 12 suitably according to the intensity | strength calculated | required by the site | part, when it distribute | arranges to the arm cover 10. FIG.

  The thickness of the coating layer 13 is preferably 1.0 to 10 μm. If it is above the lower limit of this range, it is possible to prevent defects such as pinholes from occurring in the coating layer 13 and expose the internal metal wire 12, and if it is below the upper limit of this range, the metal fibers 11 Therefore, it is possible to maintain flexibility suitable for weaving into 1 and to prevent the conductivity of the metal wire 12 from being impaired.

Moreover, the following are mentioned as a suitable thing of the said conductive fiber which can be used as the wiring 2. As shown in FIG.
The conductive fiber may be a metal wire composed of at least one selected from copper wire, aluminum wire, titanium wire, gold wire, and silver wire, or may be copper wire, aluminum wire, titanium wire It may be an alloy metal wire composed of an alloy containing at least one selected from a wire, a gold wire, and a silver wire, or copper, on the surface of the metal wire or the alloy metal wire, It may be a metal composite wire formed by coating a metal or alloy containing at least one selected from aluminum, titanium, gold, and silver.

When the conductive fiber is the metal wire, the alloy metal wire, or the metal composite wire, a signal from the detection electrode unit 3 can be reliably transmitted.
Further, since these metal wires have rigidity, when the wearer wears or removes the arm cover 10, the metal wires woven into the textile 1, the alloy metal wires, and the metal composite Even if physical stress (mechanical stress) is applied to the wire, it can withstand it sufficiently.

  The metal wire, the alloy metal wire, and the metal composite wire are preferably a titanium-coated metal wire, a titanium-coated alloy metal wire, and a titanium-coated metal composite wire in which titanium is coated around the wire. By covering with titanium and preventing these metal wires from being exposed, the corrosion resistance and conductivity of these metal wires can be further increased.

The conductive fiber is a single wire or a stranded wire having a central conductor diameter of 0.030 mm or less, and is constituted by a micro coaxial cable having a coaxial structure and a jacket (jacket) diameter of 0.5 mm or less. It is preferred that
The conductive fibers having such an extremely fine structure do not take excessive space in the textile 1 when woven into the textile 1, and do not give unnecessary tension (tension) to the textile 1. Furthermore, since the conductive fiber having an extremely fine configuration has sufficient flexibility, it is excellent in detachability when the wearer wears or removes the arm cover 10 formed of the textile 1. In addition, the coaxial cable has an advantage that high-speed data communication using a high frequency is possible.

  The textile 1 in which the conductive fiber is woven is singly selected from the metal wire, the alloy metal wire, the metal composite wire, the titanium-coated metal wire, the titanium-coated alloy metal wire, and the titanium-coated metal composite wire. What weaved may be sufficient and what weaved combining 2 or more types may be sufficient.

  The wiring 2 is a conductive fiber selected from the metal wire, the alloy metal wire, the metal composite wire, a titanium-coated metal wire, a titanium-coated alloy metal wire, and a titanium-coated metal composite wire in the textile 1. The non-coaxial cable which consists of, and the said extra fine coaxial cable may be woven together. Depending on the conductive characteristics of each cable, the type of electrode (sensor) of the detection electrode unit 3 can be appropriately changed and provided, and a more functional arm cover 10 can be realized.

  When the wiring 2 is an optical fiber, crosstalk between the wirings 2 does not occur, so that the wiring 2 can be closely woven into the textile 1 so as to be adjacent to each other. Since the wiring 2 made of an optical fiber is excellent in lightness, the burden on the wearer when it is densely woven into the textile 1 can be reduced. Furthermore, the wiring 2 made of an optical fiber is excellent in durability because it hardly corrodes even when it is exposed to moisture by sweating by the wearer.

The optical fiber is not particularly limited as long as it can transmit a signal from the detection electrode unit 3 and is made of a material that can be woven into the textile 1. For example, any one of a silica-based optical fiber, a glass-based optical fiber, a plastic optical fiber, and an optical fiber obtained by combining them is preferable.
The optical fiber may be either a single mode optical fiber (SMF) or a multimode optical fiber (MMF).

  Since the silica-based optical fiber and the glass-based optical fiber have a small transmission loss, even a signal from a light source (detection electrode unit 3, connector unit 4, 8) having a small output can be sufficiently transmitted.

  As said plastic optical fiber, what consists of resin (plastic) which polymerized polymethyl methacrylate (PMMA), styrene, etc. is mentioned. The plastic optical fiber is particularly suitable when woven into the textile 1 having high flexibility because it is strong against bending and is not easily broken.

  The core diameter of the optical fiber is preferably in the range of 0.005 mm to 2 mm, more preferably in the range of 0.01 mm to 1.5 mm, and still more preferably in the range of 0.1 mm to 1.0 mm. When the optical fiber is woven into the textile 1, when the optical fiber is woven into the textile 1, when the optical fiber is woven into the textile 1, when the optical fiber is woven into the textile 5, Can be provided with the appropriate flexibility required. That is, from the viewpoint of giving flexibility to the optical fiber wiring, the thinner the optical fiber wiring is preferable, and from the viewpoint of increasing the rigidity of the optical fiber wiring and increasing the amount of signal transmission, the thicker the optical fiber wiring is preferable.

  The thickness of the optical fiber cladding is appropriately adjusted according to the core and cladding materials. Further, the optical fiber wiring may be covered with a resin or the like. The coating can protect the optical fiber wiring from impact, friction, ultraviolet rays, moisture, and the like.

  In the arm cover 10 of the present invention, it is preferable that only one detection electrode portion 3 is provided for one wiring 2. The position of the detection electrode unit 3 in the wiring 2 is not particularly limited, but it is preferable to arrange the detection electrode unit 3 at the end of the wiring 2. It is easier in manufacturing to connect the detection electrode unit 3 to the end (terminal) of the wiring 2 than to connect the detection electrode unit 3 to the middle of the wiring 2.

  In the arm cover 10 of the present invention, when only one detection electrode unit 3 is provided for one of the wires 2, the wire 2 transmits only the signal of the detection electrode unit 3, and thus the detection is performed. The signal transmitted and / or received by the electrode unit 3 (or the connector unit 4) can be made more complicated (capacity increased).

  In the arm cover 10 of the present invention, two or more detection electrode portions 3 may be provided for one of the wires 2. In this case, the wiring 2 can collectively transmit signals obtained from the detection electrode portions 3 arranged at a plurality of locations in the arm cover 10.

  In the arm cover 10 of the present invention, a plurality of wires 2 are connected to one connector 4, and the wires 2 are configured to have bent portions 9 at appropriate positions in the textile 1 (see FIG. 1 and FIG. 1). 2) Signals obtained from a plurality of detection electrode portions 3 arranged at desired positions in the arm cover 10 (textile 1) are integrated into the one connector 4 through the plurality of wirings 2. be able to. The integrated signal can be processed by an external device connected to the connector 4.

  Further, in the arm cover 10 of the present invention, one wire 2 is connected to one connector 8, and the wire 2 is substantially linear along the warp or weft in the textile 1. When woven (FIGS. 4 and 5), a signal transmitted via the wiring 2 can be further transmitted to an external device (not shown) by the connector 8. Manufacturing is easier because the wiring 2 and the connector 8 have a simple configuration with a one-to-one correspondence. Further, since the wiring 2 is substantially straight and does not have the bent portion 9, it is easier to weave into the textile 1.

<Method of weaving wiring into textile>
The textile 1 is a fabric part that constitutes the arm cover 10 for measuring the myoelectric potential prosthesis, and can be produced as a known garment fiber such as cotton or polyester is woven by plain weaving, and the wiring 2 is further woven. The weaving method of the garment fibers is not limited to plain weave {method of weaving weft (warp) and warp (weft) alternately vertically and vertically} (FIG. 7). A twill weave of a sentence (FIG. 8) or a twill weave of three sheets (FIG. 9) can be applied.

  The method for weaving the wiring 2 into the textile 1 is not particularly limited as long as it is a method for weaving the wiring 2 at a predetermined position of the textile 1. For example, it can be manufactured by weaving the wiring 2 in the textile 1 using a loom M as shown in FIG. The manufacturing method will be described below.

  The loom M includes a rod-shaped front beam 30 and a back beam 31 that are horizontally spaced apart from each other, a take-up roller type cross beam 32 installed under the front beam 30, and a A feed roller type warp beam 33 disposed in the first beam 35, a first rod 35 and a second rod 36 which are movably installed in an intermediate position between the front beam 30 and the back beam 31, and these rods 35. , 36 and the front beam 30 are disposed between the flanges 35, 36 and the front beam 30 so as to be movable in the horizontal direction, and between the flange 37 and the front beam 30, the front beam is disposed. 30 and a shuttle 39 provided so as to be movable in a parallel direction.

  In FIG. 10, the support mechanism for the front beam 30, the back beam 31, the cross beam 32, and the warp beam 33 is omitted, but the front beam 30 and the back beam 31 are fixedly supported by a portal frame or the like. The cross beam 32 and the warp beam 33 are rotatably supported around their circumferences by a rotation support mechanism such as a gate-shaped frame or a bearing (not shown). Also, the collars 35 and 36 are supported by a frame (not shown) so as to be movable in parallel up and down, and the collar 37 is also supported by a frame (not shown) so that it can be translated in the horizontal direction.

  The collars 35, 36 are configured by individually separating a plurality of wire-shaped heald members 43 between the upper frame 41 and the lower frame 42 and laying them in parallel. A wire is formed in a ring shape at the center of each heald member 43. A formed hole 44 is formed. These heald holes 44 are configured to pass the warp 51 as will be described later. In this embodiment, the flanges 35 and 36 are arranged in such a positional relationship that the heald members 43 formed on them are alternately arranged side by side, and a plurality of them are hung on the front beam 30 and the back beam 31 in parallel as will be described later. Each warp 51 to be passed is arranged so that it can be passed through the heald holes 44 of the respective ridges 35, 36.

  These rods 35 and 36 are provided so as to be individually movable up and down by a vertical drive mechanism (not shown), and the vertical movements of the rods 35 and 36 are alternately repeated. For example, as shown in FIG. 10, when the reed 35 moves downward and the reed 36 moves upward, the group of alternate warps 51 supported by the reed 35 by the heald member 43 is pulled downward. By pulling the other group of other warps 51 supported by the heald member 43 by the heel 36 upward, one group of warps 51 and the other group of warps 51 A large gap can be formed between the two. By forming this gap, the shuttle 39 can move in the direction intersecting the warp 51 as will be described later. Conversely, when the reed 35 moves upward and the reed 36 moves downward, the vertical relationship between the first group of warps 51 and the other group of warps 51 is reversed. Can pass through the warp yarns 51 in the crossing direction through a gap between the group of warp yarns 51.

  In addition, the heel 37 includes a plurality of wings 47 in parallel between the upper frame 45 and the lower frame 46, and the front beam 30 and the back beam 31 are interposed between the wings 47. A plurality of warp yarns 51 that are stretched in parallel are arranged so that they can be inserted, and the wings 47 can be moved in parallel to the front beam 30 in this state. In FIG. 10, the details of the individual support moving mechanisms of the eaves 35 and 36 and the eaves 37 are omitted, and only their operating directions are indicated by arrows.

  Of the textile 1 described above, the weft 52 is wound around the shuttle 39, and the shuttle 39 is provided so as to be movable in parallel with the front beam 30 along the length direction of the front beam 30. Thus, the weft 52 can be freely fed out from the shuttle 39 at a required length.

Next, an example of a method for manufacturing the textile 1 having the configuration shown in FIG. 7 using the loom M having the configuration shown in FIG. 10 will be described.
In order to manufacture the textile 1, a necessary number of warp yarns 51 made of clothing fibers mainly constituting the textile 1 are stretched in parallel between the front beam 30 and the back beam 31 of the loom M. At this time, the warp 51 made of the wiring 2 is stretched at a predetermined position. In the embodiment shown in FIG. 10, only an outline is shown, but a plurality of warped yarns 51 are stretched between the front beam 30 and the back beam 31 so as to pass through the respective heald holes 44 of the hooks 35 and 36. Set it up. Further, a weft 52 made of clothing fibers is wound around the shuttle 39 for a required length.

  If the hooks 35 and 36 are alternately moved up and down from the state described above, the warp 51 can be divided into two groups and moved up and down as shown in FIG. A large gap is generated between the warps 51. When the weft 52 wound around the shuttle 39 is moved together with the shuttle 39 from one end side of the front beam 30 to the opposite end side using this gap, the weft 52 is moved to one of the warp yarns 51 as the shuttle 39 moves. It can be woven in the direction of crossing every other book.

  When the shuttle 39 passes through all the rows of the warp yarns 51 and moves to the opposite end side of the front beam 30, every other warp yarn 52 can be woven into all the warp yarns 51. Is moved to the front beam 30 side and the weft 52 can be driven by performing an operation of pushing the weft 52 into the front beam 30 side. Then, after the shuttle 39 has driven the wefts 52 woven through all the rows of the warps 51 as described above, the vertical positions of the hooks 35 and 36 are reversed, and the group of the warps 51 divided into two is switched up and down. Therefore, the first shuttle 39 is moved again in the reverse direction along the front beam 30 to return it to the previous position, and the weft yarns 52 can be woven into every other warped yarn 51 stretched.

  By repeatedly performing the above operation, the wefts 51 for each woven and arranged row can be driven and brought into close contact with the wings 47 of the heel 37. Moreover, the wiring 2 can be woven as a warp 51 at a predetermined position of the textile 1 mainly composed of clothing fibers.

  In addition, the wiring 2 can be woven as a weft 52 at a predetermined position of the textile 1. In this case, a necessary length of clothing fiber is wound around the shuttle 39 and a second shuttle (not shown) around which the wiring 3 is separately wound is prepared, and appropriately interposed between the weft yarn 52 made of clothing fiber. The operation of weaving the second shuttle may be performed.

  Further, when the wiring 2 has the bent portion 9 as in the textile 1 shown in FIG. 1, the process is temporarily stopped in the process of weaving the textile 1 as described above, and only the warp 51 made of the wiring 2 is backed. Disconnected from the beam 31, removed from the heald hole 44 and the heel 37, arranged adjacent to and parallel to the weft 52, and resumes the weaving of the textile, so that the wiring 2 is moved from the warp 51 direction to the weft 52 direction at a predetermined position. It can be set as the textile 1 which has the bending part 9 bent.

  On the contrary, in the process of weaving the wiring 2 into the textile 1 as the weft 52, the wiring 2 is fixed to the back beam 31 through the heald hole 44 and the hook 37 and arranged in parallel with the warp 51. By resuming the weaving of the textile, the textile 1 having the bent portion 9 in which the wiring 2 is bent from the direction of the weft 52 to the direction of the warp 51 at a predetermined position can be obtained.

The myoelectric potential measurement of the present invention is performed by appropriately forming or sewing the textile 1 manufactured as described above by a known method and connecting the detection electrode unit 3 to one end side of the wiring 2 sewn into the textile 1. Prosthetic arm covers can be manufactured.
The detection electrode unit 3 may be arranged after being connected to the wiring 2 after the production of the textile 1 in which the wiring 2 is woven, or the wiring 2 to which the detection electrode unit 3 is connected in advance is connected to the textile 1. By weaving, it may be arranged in the textile 1 simultaneously with the wiring 2.

The invention according to claim 14 will be described below. The arm cover (textile wiring) for prosthetic hand measurement of the present invention can connect a plurality of detection electrodes that are in contact with the skin surface on the extensor group and the flexor group remaining at the stump and one connector. Therefore, when weaving the warp and weft of the textile, conductive fibers are used in a part thereof, and the conductive fibers are bent and woven in place from a plurality of detection electrode sides, so that the one connector and This is a textile wiring in which a plurality of detection electrodes can be connected.
By using the textile wiring having such a structure, a plurality of detection electrodes and one connector can be easily connected, and the myoelectric potential can be reliably measured. In addition, since the necessary number of conductive fibers can be incorporated into the textile, it will have the flexibility and strength of the textile compared to those placed on conventional toweling, etc., and it will excel in the flexibility to follow body movements. At the same time, the problem that the wiring is exposed during use is eliminated.
Furthermore, the textile wiring of the present invention can be manufactured by being woven into a sleeve portion of clothing or the like from the beginning. In addition, the detection electrode can be manufactured separately from clothing or the like so as to be fixedly attached.

  And the position which bends and weaves a conductive fiber in textiles may make all the conductive fibers the same position, or may make it a different position. In the case where bending is woven at the same position, it is advantageous from the viewpoint of manufacturing. However, when bending is woven at different positions, the flexibility of the textile wiring is improved. In the above description, the textile wiring structure is an example of connecting a plurality of detection electrodes brought into contact with the skin surface on the extensor group and the flexor group and one connector, but in the case of two connectors. Similarly, it is possible to bend and weave the conductive fibers.

Further, as the conductive fiber used for the textile wiring, a fibrous body having a thickness similar to that of the warp and weft used for the textile is used. In addition, as a material thereof, a metal wire composed of at least one selected from a copper wire, an aluminum wire, a titanium wire, a gold wire, and a silver wire, or an alloy containing at least one selected from these. Using an alloy metal wire composed of, or a metal composite wire composed by coating the surface of the metal wire or the alloy metal wire with a metal or alloy containing at least one selected from these, Also, a highly conductive fiber such as a micro coaxial cable having a central conductor diameter of 0.030 mm or less, a single wire or a stranded wire having a coaxial structure and a jacket (jacket) diameter of 0.5 mm or less A body is used. Moreover, it is good also as conductive fiber which coat | covers these fibrous bodies with plastic, or has a coating | cover like a magnet wire. The textile wiring configured as described above can measure the myoelectric potential with certainty and has sufficient flexibility to follow the movement of the body, so that the connected conductive fibers are not exposed.
Furthermore, the metal wire, the alloy metal wire, or the textile wiring in which the metal composite wire and the micro coaxial cable are woven simultaneously can be used.
The conductive fibers may be woven simultaneously with either the warp yarn or the weft yarn of the textile instead of the conductive fiber alone.

The invention of claim 14 will be described with reference to FIG. FIG. 1 is a schematic development view of a textile wiring 10 for a myoelectric potential prosthetic hand showing an example of the present invention. In the textile 1 constituting the textile wiring 10, conductive fibers 2 (wiring 2) for connecting a plurality of detection electrodes 3 (detection electrode portions 3) and one connector 4 are arranged by bending weaving. . In this way, the conductive fiber 2 is woven into the textile 1 by weaving the warp and weft of the textile 1 at the same time, or by weaving the conductive fiber 2 so that the direction of the conductive fiber 2 is changed at an appropriate position of the textile 1. Therefore, the conductive fiber 2 behaves integrally with the textile 1, and the conductive fiber 2 is not excessively stressed. For this reason, even if the conductive fibers 2 are connected to the plurality of detection electrodes 3 and one connector 4, there is no positional displacement or exposure of the conductive fibers 2 due to the movement of the body, and the conductive fibers 2 are brought into close contact with the body and the prosthetic hand. Can be used.
In addition, here, the textile 1 shows a case where the plurality of detection electrodes 3 brought into contact with the extensor group and the flexor group of the forearm portion 5 of the prosthetic wearer 5 and one connector 4 are connected. It can cope with the case of two.

  The textile 1 described above can be produced by a generally known loom. For example, when the textile wiring 10 is woven into a sleeve portion of a long-sleeved shirt or the like, a plurality of non-conductive fiber warp yarns are stretched in parallel, and the non-conductive fiber weft yarns cross the warp yarns with respect to the warp yarns. And weaving the weft yarn, weaving the conductive fiber 2 in the direction intersecting the weft yarn, and in the state where the conductive fiber 2 is changed in the weft direction and positioned in the weft direction in the middle of weaving, Obtained by weaving the conductive fibers 2 into the weft yarns or warp yarns of the non-conductive fibers by using the warp yarns of the non-conductive fibers in combination with the weaving operation including the weft yarn and the conductive fibers 2 whose direction has been changed. be able to. In this way, the conductive fibers 2 can be arranged at a necessary location of the textile by bending weaving, and are used as textile wiring.

Next, FIG. 3 shows a schematic view when the textile wiring 10 (arm cover 10) having the structure of FIG. 1 is worn on an arm to which a prosthetic hand is attached. The textile wiring 10 is configured by connecting the conductive fibers 2 to one connector 4 attached to the hand portion 7 of the prosthesis on the opposite side of the detection electrode portion 3 attached to the surface of the arm. The connector 4 is connected to a motor 6 via a myoelectric potential measuring device and a battery. Then, the myoelectric potential measuring device controls the battery current to the motor 6 in accordance with the change of the myoelectric potential from the detection electrode unit 3, thereby driving the motor 6 and moving the hand portion 7 and the finger portion of the prosthetic hand. Can be bent and stretched. With such a configuration, the mounted prosthetic hand can be covered with the textile wiring 10 so that the prosthetic hand part other than the hand part 7 is not exposed.
The textile wiring 10 as in the present invention has the flexibility and strength of the textile 1 as compared with the textile wiring 10 that is provided on the towel 1 or the like because the necessary number of conductive fibers 2 can be woven into the textile 1. Therefore, there is flexibility to follow the movement of the body, and there is no problem that the wiring connected to the detection electrode 3 and one connector 4 is exposed during use.

  The invention of claim 15 will be described with reference to FIG. The textile wiring 10 is linear on a part of the warp or the weft so that the plurality of detection electrodes 3 and the plurality of connectors 8 that are in contact with the skin surface on the extensor and flexor groups remaining at the stumps can be connected. This is the textile wiring 10 when the conductive fiber 2 is woven into the fabric. Since the textile wiring 10 having such a structure has the flexibility and strength of the textile 1 because the conductive fibers 2 need only be woven into the textile 1 as the required number of warps or wefts, it is flexible to follow the movement of the body. In addition to being excellent in performance, there is no problem that the conductive fibers 2 are exposed whether the connector 3 is connected to a plurality of connectors 8 during use. Moreover, it is most preferable that the textile wiring 10 is made into the textile wiring 10 so as to be woven into a portion corresponding to a prosthetic hand when manufacturing clothing.

  Although the invention of claim 14 and the invention of claim 15 described above are cases where conductive fibers are used as the wiring 2 of the textile 1, an optical fiber may be used as the wiring 2 of the textile 1.

  A textile wiring having a structure as shown in FIG. 1 was produced by bending weaving as the arm cover 10 shown in FIG. As the conductive fiber, an ultrafine coaxial cable (AWG46) was used. The arm cover 10 was placed on the artificial hand attached to the arm, and the conductive fibers of the arm cover 10 were connected to the six detection electrodes 3 attached to the surface of the arm and one connector of the artificial hand. In this state, the subject was instructed to bend and stretch the wrist, and the hand portion of the technician was operated to measure the myoelectric potential and observe the state of the conductive fibers of the textile wiring. As a result, it was confirmed that the myoelectric potential was reliably measured, and had sufficient flexibility to follow the movement of the body, and the conductive fibers connected to the electrodes were not exposed. As described above, it was confirmed that the arm cover for a prosthetic arm for measuring myoelectric potential was sufficiently useful in practice.

  The myoelectric measurement prosthetic arm cover according to the present invention can be widely used in the field of myoelectric prostheses and the like.
