Description

  The present invention relates to a biological information measuring apparatus applicable to, for example, a body composition meter or a weight scale that measures biological information based on biological impedance.

  Biological information measuring devices that measure biological information such as body weight and body fat are widely used. For example, Patent Document 1 described below describes a living body measuring apparatus with a weight scale in which a colorless transparent conductive film is formed on a colorless transparent plate-like outer stage such as methacrylic resin or glass.

JP 2001-228013 A

  When the conductive film is formed on the platform in the apparatus described in Patent Document 1, generally, after placing the platform in the chamber, the inside is evacuated, and the conductive film is deposited over the entire surface of the platform. . Then, unnecessary conductive films are removed by etching. In this method, when the size (size) of the platform is different, there is a problem that the efficiency in the manufacturing process may be reduced because the number of platforms that can be stored in the chamber varies.

  Therefore, the present invention provides a biological information measuring apparatus in which a conductive film is formed only on the electrode portion of the electrode unit, not on the entire surface of the mounting table, thereby improving efficiency in the manufacturing process and reducing costs for maintenance. One of the purposes is to provide.

  In order to solve the above-described problems, the present invention provides biological information including an electrode unit in which an electrode part is formed, a wiring part connected to the electrode part, and a mount on which a mounting part to which the electrode unit is attached is formed. It is a measuring device. With this configuration, it is not necessary to form a conductive film over the entire upper surface of the mounting table.

  In the biological information measuring device, a plurality of attachment portions may be formed on the mounting base. In the biological information measuring device, the electrode unit may be detachable from the attachment portion. With this configuration, even when a problem occurs in some of the electrode units, only the electrode unit can be removed from the mounting portion and replaced.

  In the biological information measuring apparatus, a through hole that communicates with the inside and outside of the platform may be formed on the top surface of the platform, and the electrode unit may be exposed through the through hole. With this configuration, the electrode portion can be disposed in the vicinity of the toe of the foot or in the vicinity of contact with the heel.

  In the biological information measuring device, the attachment portion may be a recess formed on the upper surface of the mounting table. Moreover, the open end may be formed in the recessed part because the recessed part leads to the side surface of the mounting base. With this configuration, the electrode unit can be attached to and detached from the platform without removing the cover member of the platform.

  In the biological information measuring device, the electrode unit may include a base portion on which the electrode portion is formed, and the electrode portion may have a transparency that allows the base portion to be visually recognized. With this configuration, the user can recognize the color, pattern, and the like of the base portion of the electrode unit.

  According to the present invention, it is possible to improve the efficiency in the manufacturing process of the biological information measuring device and reduce the cost for maintenance. Note that the contents of the present invention are not construed as being limited by the effects described in the present specification.

In the embodiment described below, an example in which the present invention is applied to a body composition meter having a function of measuring biological information will be described. As biological information, height, weight, fat percentage, visceral fat level, body water content, muscle mass, basal metabolism, bone mass, lean mass, somatic cell volume, blood pressure, visceral fat area, BMI, obesity, intracellular Examples of the liquid amount and the amount of extracellular fluid can be given.

"Appearance of body composition meter"
First, an example of the external shape of a body composition meter (body composition meter 1) according to an embodiment of the present invention will be described with reference to FIGS. 1 is a plan view of the body composition meter 1, FIG. 2 is a left side view of the body composition meter 1, and FIG. 3A is a perspective view of a cover member (cover member 10a) included in the body composition meter 1. 3B is a cross-sectional view showing a cross section when the cover member 10a is cut along the cutting line AA in FIG. 3A.

  The body composition meter 1 has a platform 10. The platform 10 includes a cover member 10a having a longitudinal direction and a short side direction, and a bottom plate member 10b attached to the cover member 10a. The cover member 10 a has an upper surface 11, lateral sides 13 and 14, and longitudinal side surfaces 15 and 16, and has a U-shaped cross section in the longitudinal direction and the lateral direction. . The upper surface 11 of the cover member 10a is substantially flat for the user of the body composition meter 1 to be placed (stand). The cover member 10a and the bottom plate member 10b are made of, for example, a resin member (for example, ABS resin (acrylonitrile / butadiene / styrene copolymer)). The cover member 10a and the bottom plate member 10b are not limited to resin, and may be metal or the like.

  In the vicinity of the four corners of the upper surface 11 of the cover member 10a, rectangular through holes (through holes 20a, 20b, 20c, 20d) communicating with the inside and outside of the mounting table 10 are formed. When there is no need to distinguish individual through holes, they are appropriately referred to as through holes 20. The size of the through hole 20 is set to be approximately the same as the size of the protruding portion of the electrode unit described later.

  A blindfold 21a is formed near the left end of the through hole 20a, a blindfold 21b is formed near the right end of the through hole 20b, a blindfold 21c is formed near the left end of the through hole 20c, and the right end of the through hole 20d. A blindfold 21d is formed in the vicinity. When there is no need to distinguish between the individual blindfolded portions, they are appropriately referred to as blindfolded portions 21. The blindfold 21 has a shape in which a part of the cover member 10a is slightly raised upward, and a part of the raised part is disposed above the through hole 20 so as to hide a part of the through hole 20. (See FIGS. 3A and 3B). The blindfolded portion 21 may be formed integrally with the cover member 10a, or may be formed separately by welding, bonding, joining members such as screws, assembly, or the like.

  The conductive film is exposed through the through hole 20. Specifically, the conductive film 52a is exposed through the through hole 20a, the conductive film 52b is exposed through the through hole 20b, and the conductive film 52c is exposed through the through hole 20c. The conductive film 52d is exposed through the through hole 20d. When there is no need to distinguish between the individual conductive films, they are appropriately referred to as conductive films 52. 1, 4, 5, 6, and 7, dot-like hatching is given to the conductive film 52.

  The conductive film 52 exposed through the through hole 20 functions as an electrode. The conductive film 52a and the conductive film 52b function as a current supply electrode for supplying a current to the user's body from a body part (for example, a sole on the toe side) in contact with the user. On the other hand, the conductive film 52c and the conductive film 52d are voltage detections for detecting a voltage generated between the parts of the body in contact with the user (for example, between the right heel side and the left heel side body). Functions as an electrode. Based on the value of the supplied current and the detected voltage, the bioimpedance of the user can be obtained. During normal use of the body composition meter 1, the sole on the toe side of the user's left foot is in contact with the conductive film 52a, and the sole on the heel side of the user's left foot is in contact with the conductive film 52c. Further, the sole on the toe side of the user's right foot is in contact with the conductive film 52b, and the sole on the heel side of the user's right foot is in contact with the conductive film 52d.

  A space is formed inside the cover member 10a and the bottom plate member 10b, and the display unit 23, the load cell, the control board, and the like are accommodated in this space. A rectangular opening 28 corresponding to the shape of the display unit 23 is formed at the approximate center of the cover member 10 a, and the display unit 23 is configured to be visible through the opening 28. The display unit 23 includes an LCD (Liquid Crystal Display) organic EL (Electro Luminescence) or the like, and the weight, body fat, etc. of the user after measurement are displayed on the display unit 23.

  The body composition meter 1 has, for example, four leg portions (leg portions 25a, 25b, 25c, 25d). When there is no need to distinguish individual legs, they are appropriately referred to as legs 25. For example, holes corresponding to the leg portions 25 are formed at the four corners of the bottom plate member 10b, and the leg portions 25 protrude downward through the hole portions.

  A weight sensor (not shown) is disposed in the mounting base 10. As the weight sensor, for example, a load cell composed of a strain body and a strain gauge can be used. One end of the strain body is supported by an inner surface (a surface opposite to the upper surface 11) 12 of the cover member 10 a, and the other end of the strain body is supported by the leg portion 25. When the strain generating body bends due to a load when the user is placed on the upper surface 11 of the platform 10, the strain gauge expands and contracts and the resistance value (output value) changes according to the expansion and contraction of the strain gauge. The body weight can be measured by using this resistance change as a change in the load signal output.

  The body composition meter 1 has an operation input unit (not shown). The operation input unit is formed on the upper surface 11 of the cover member 10a, for example. The operation input unit is a touch switch (also referred to as a touch panel or the like) that can be operated by approaching or touching a finger. Although the touch switch method is not limited to a specific method, an example is a capacitance method that detects a change in capacitance caused by bringing a finger close to or in contact with the finger. The operation input unit is not limited to a touch switch, and may be a mechanical switch (for example, a push switch pressed by a user).

  The mounting table 10 of the body composition meter 1 is formed with a mounting portion to which an electrode unit to be described later is mounted. On the mounting table 10 of the body composition meter 1, for example, attachment portions are formed at four locations (four) corresponding to the number of electrode units.

About the electrode unit
Next, the electrode unit included in the body composition meter 1 will be described. FIG. 4 is an exploded perspective view for explaining a configuration example of the electrode unit 40 according to the embodiment of the present invention. The electrode unit 40 generally includes an electrode part 41 and a base part 42 that supports the electrode part 41.

  The electrode part 41 has a substantially plate-like film 51. The film 51 is formed of polyethylene terephthalate (PET), polyimide, or the like, and a conductive film 52 is formed on a predetermined surface (for example, an upper surface).

  As the material of the conductive film 52, for example, one or more selected from the group consisting of a metal oxide material having electrical conductivity, a metal material, a carbon material, a conductive polymer, and the like can be used. Examples of the metal oxide material include indium tin oxide (ITO), zinc oxide, indium oxide, antimony-added tin oxide, fluorine-added tin oxide, aluminum-added zinc oxide, gallium-added zinc oxide, silicon-added zinc oxide, and zinc oxide. -Tin oxide system, indium oxide-tin oxide system, zinc oxide-indium oxide-magnesium oxide system, etc. are mentioned.

  As the metal material, for example, metal nanoparticles, metal wires, and the like can be used. Specific examples of these materials include copper, silver, gold, platinum, palladium, nickel, tin, cobalt, rhodium, iridium, iron, ruthenium, osmium, manganese, molybdenum, tungsten, niobium, tantel, titanium, bismuth, Examples thereof include metals such as antimony and lead, and alloys thereof. Examples of the carbon material include carbon black, carbon fiber, fullerene, graphene, carbon nanotube, carbon microcoil, and nanohorn. As the conductive polymer, for example, substituted or unsubstituted polyaniline, polypyrrole, polythiophene, and one or two (co) polymers selected from these can be used. As a method for forming the conductive film 52, for example, a PVD (Physical Vapor Deposition) method such as a sputtering method, a vacuum deposition method, or an ion plating method, a CVD (Chemical Vapor Deposition) method, a coating method, a printing method, or the like is used. Can do.

  The base portion 42 has a base 61 and a protruding portion 62. The base 61 is, for example, a thin plate-shaped member having a longitudinal direction and a short direction, and a cross section in the short direction is a U-shape. The base 61 has an upper wall 611 and side walls 612 and 613 that stand downward from both ends of the upper wall 611.

  The protruding portion 62 is a thin plate-like member that protrudes upward from the approximate center of the upper wall 611, and the size of the upper surface thereof is set substantially the same as the outer shape of the film 51. The base 61 and the projecting portion 62 are made of resin or the like, and both may be integrally formed, or those formed separately may be joined by welding, bonding, joining members such as screws, assembly, or the like. A rectangular attachment hole 63 is formed in the upper wall 611 of the base 61. The attachment hole 63 is formed from one end surface 614 of the upper wall 611 toward the center of the base 61 and communicates with the end surface 622 of the protruding portion 62.

  Next, an example of an assembly method of the electrode unit 40 will be described. First, the conductive film 52 is formed on the upper surface of the film 51 to form the electrode portion 41. Then, the electrode portion 41 is bonded to the upper surface 621 of the protruding portion 62 so that the conductive film 52 faces upward. The electrode unit 41 may be bonded to the upper surface 621 using a double-sided tape or an adhesive, or may be bonded to the upper surface 621 using a vacuum bonding apparatus (OCR method) or the like. The electrode unit 40 is completed by joining the electrode part 41 to the base part 42.

  FIG. 5A shows a wiring portion 43 according to an embodiment of the present invention. The wiring portion 43 has a clip portion 71 having a U-shape and made of metal or the like, and a cable 72 connected to the clip portion 71. The clip part 71 is in contact with at least the conductive film 52. The cable 72 is connected to a control board housed in the platform 10. The clip portion 71 is set to a size that can sandwich the protruding portion 62 to which the film 51 is bonded.

  The wiring part 43 is attached to the electrode unit 40 as follows, for example. The clip portion 71 of the wiring portion 43 is inserted from the attachment hole 63, and the clip portion 71 is sandwiched near the end surface 622 of the protruding portion 62. As a result, as shown in FIG. 5B, the wiring portion 43 is connected to the electrode unit 40, and the conductive film 52 and the clip portion 71 come into contact with each other to be electrically connected.

"Example of electrode unit installation"
The example which attaches the electrode unit 40 mentioned above to the mounting base 10 is demonstrated. As shown in FIG. 6, four electrode units 40 (electrode units 40a, 40b, 40c, 40d) to which the wiring portion 43 is connected are prepared, and a pair of left and right electrode units (for example, electrode units 40a, 40b) are prepared. Align them in opposite directions. In the following description, the electrode unit 40a is described as an example, but the same applies to the other electrode units 40b and the like. The electrode unit 40a has the same configuration as that of the electrode unit 40, and the reference numerals attached to the electrode unit 40 and the wiring unit 43 are referred to as the respective parts of the electrode unit 40a and the wiring unit connected to the electrode unit 40a. A reference sign with “a” is attached.

  The electrode unit 40a is attached to the inner surface 12 of the cover member 10a so that the conductive film 52a of the electrode unit 40a is exposed from the through hole 20a of the cover member 10a. On the inner surface 12 of the cover member 10a, attachment portions such as claws, screws, and hooks are formed near the periphery of the through hole 20a. There may be a plurality of claws, screws, etc. in each mounting portion. The electrode unit 40a is attached to the inner surface 12 of the cover member 10a by this attachment portion.

  As shown in FIG. 7, when the electrode unit 40a is attached, the vicinity of the clip portion 71a is hidden by the blindfold portion 21a, and the clip portion 71a and the cable 72a are not exposed. Thereby, it is preventing that the designability (design property) of the body composition meter 1 is impaired. The body composition meter 1 is formed by connecting the cable 72a of the electrode unit 40a to the control board and combining the cover member 10a and the bottom plate member 10b. Note that the cable 72 a may be connected to the control board after the electrode unit 40 a is attached to the platform 10.

  In addition, you may attach the base 42a of the electrode unit 40a to the attaching part provided in the baseplate member 10b instead of the cover member 10a. For example, a frame-shaped attachment portion is formed at a position corresponding to the lower side of the through hole 20a on the inner surface of the bottom plate member 10b. You may insert and attach the electrode unit 40a to this attaching part. By attaching the cover member 10a after attaching the electrode unit 40a to the attachment portion of the bottom plate member 10b, the conductive film 52a is exposed from the through hole 20a.

  In one embodiment of the present invention, after removing the cover member 10a and the bottom plate member 10b, the electrode unit 40a can be removed from the mount 10 by releasing the attachment state by the attachment portion. That is, the electrode unit 40a is detachably attached to the mounting portion of the mounting base 10. Furthermore, for example, only the electrode unit 40a among the four electrode units 40 can be independently attached to and detached from the mounting portion of the mounting base 10.

According to the body composition meter 1 in one embodiment of the present invention described above, the effects exemplified below can be obtained.
There is no need to form a conductive film directly on a platform made of a glass substrate or the like as in the prior art.
When a defect occurs in an electrode due to a scratch on a specific conductive film, only the electrode unit may be removed and replaced (including the wiring portion). That is, it is not necessary to replace all the platforms made of glass substrates or the like, and the cost for maintenance (maintenance cost) can be reduced.
By sharing the electrode unit according to one embodiment as a common component, it is possible to cope with a difference in the size of the mounting table and the arrangement of the electrodes in the body composition analyzer with different designs. Become.
A common electrode is often a base color of a metal plate such as stainless steel or an oxide film color (black) formed on the metal plate for rust prevention. However, for example, by making the conductive film and the film transparent and changing the color and the pattern of the base, the electrode portion of the mounting table can be set to various colors and patterns. Moreover, the combination of the color of a mounting base and the color of an electrode part can be changed easily, and the design property of a body composition meter can be improved. In this case, the conductive film and the film may be transparent so long as the color and pattern of the base portion of the electrode unit can be visually recognized.
