  By the way, in the belt type body fat measuring device of Patent Document 1, all of the first electrode 4, the second electrode 5, and the pair of third electrodes 6 a and 6 b are fixedly installed on the belt member 3.

  For this reason, in particular, the pair of third electrodes 6a and 6b contacting the flank position 1c is strongly pressed against the abdomen 2 when the wrapping force around the abdomen 2 of the belt member 3 is too strong. Changes and tends to affect measurement accuracy. On the other hand, if the winding force of the belt member 3 is too weak, it is difficult to contact the abdomen 2, and similarly, the measurement accuracy is likely to be affected.

  The present invention has been made to remedy the above problems, and provides a belt type body fat measuring device devised so that a pair of third electrodes can be installed on a belt member so as not to affect the measurement accuracy. It is for the purpose.

  In order to solve the above problems, the present invention provides a belt member that is wound around the abdomen of the subject, a first electrode that contacts the umbilicus position on the body surface of the subject, a second electrode that contacts the back position, A pair of third electrodes that are in contact with the flank positions are installed, a current is passed between the first electrode and the second electrode, and the measurement subject's measurement is performed based on the voltage value generated between the pair of third electrodes. A belt type body fat measuring device for measuring abdominal fat mass, wherein the first electrode and the second electrode are brought into contact with the umbilicus position and the back position by the wrapping force of the belt member, and near the flank position of the belt member. An opening is formed, and a pair of third electrodes are attached to and contacted with the measurement subject's flank from the opening to provide a belt-type body fat measurement device. .

  As in claim 2, in claim 1, the vicinity of the flank position of the belt member is formed wide, and the rectangular opening extending in the longitudinal direction of the belt member is formed in the wide portion. It is preferable.

  As in claim 3, in claim 1 or 2, the second electrode is provided so as to be slidable in the longitudinal direction of the belt member, and the belt member includes a first electrode to a second electrode. In addition to forming a mark indicating the distance, a positioning mark for a pair of third electrodes is provided on the inner edge of the opening at a position corresponding to approximately half the length of the distance between the first electrode and the mark. It is preferable to form.

  As in a fourth aspect, in the third aspect, each of the marks is preferably a scale of the circumferential length of the belt member between the first electrode and the second electrode. Here, the circumferential length of the belt member means a length measured along the longitudinal direction of the belt member, and when the belt member is wound around the abdomen of the person to be measured, the length is the circumferential length of the abdomen. Corresponds to.

  As in claim 5, in any one of claims 1 to 4, the pair of third electrodes are attached to a flexible plastic plate at a predetermined interval, and the pair of third electrodes has a person to be measured. It is preferable that a gel that can be attached with an adhesive force is adhered to the surface of the body.

  According to the present invention, the first electrode and the second electrode are brought into contact with the umbilicus position and the back position by the winding force around the abdomen of the belt member. On the other hand, the pair of third electrodes are attached to and contacted with the measurement subject's flank position through an opening formed near the flank position of the belt member. That is, the pair of third electrodes is simply attached to the measurement subject's flank position from the opening of the belt member and brought into contact therewith. Therefore, even if the winding force of the belt member is too strong, it is not strongly pressed against the abdomen, and conversely, even if the winding force of the belt member is too weak, it does not become difficult to contact the abdomen. In this way, the pair of third electrodes can be installed on the belt member so as not to affect the measurement accuracy.

  According to claim 2, by forming the rectangular opening in the wide part of the belt member, when the belt member is wound around the abdomen and pulled, the tensile force acts equally on the wide part. It won't be kinked.

  According to the third aspect, when the second electrode is slid to the back position, a mark indicating the distance from the first electrode to the second electrode is learned. Then, with reference to the mark, the pair of third electrodes are attached to the position of the measurement subject's flank according to the positioning mark of the opening. Since the positioning mark for the opening is formed at a position corresponding to half of the circumferential length of the belt member between the first electrode and the second electrode, the pair of third electrodes is connected to the first electrode. At the intermediate position between the electrode and the second electrode, it can be accurately attached to the flank position of the measurement subject.

  According to claim 4, if each mark is a scale of the circumferential length of the belt member between the first electrode and the second electrode, it is possible to easily measure the entire circumferential length of the abdomen of the measurement subject. it can.

  According to the fifth aspect, by attaching the pair of third electrodes to the flexible plastic plate at a predetermined interval, the interval between the pair of third electrodes can be accurately maintained. Further, by attaching the gel to the pair of third electrodes, the pair of third electrodes can be easily and quickly attached to the body surface of the person to be measured, and can be easily and quickly removed from the body surface of the person to be measured. be able to. Furthermore, since the plastic plate is flexible, it is easy to become familiar with the curvature of the body surface of the measurement subject.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings. Note that portions having the same configuration and operation as those of the background art are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 1 is a developed view of the belt member 13 wound around the abdomen 2 of the person 1 to be measured as viewed from the front. A buckle 20 is fixed to the base end portion 13 a of the belt member 13, and a hook-and-loop fastener (for example, a hook portion) 21 a is attached to the front surface of the buckle 20. Further, a hook-and-loop fastener (for example, a loop portion) 21b as a mating member is attached to the back surface of the front end portion 13b of the belt member 13.

  Here, in the hook-and-loop fastener, when the hook portion and the loop portion are paired and strongly pressed together, the hook portion and the loop portion are locked so that they are not easily detached from each other. Moreover, when the hook part and the loop part are strongly peeled off by hand, the hook part and the loop part are unlocked, which is also called a mechanical fastener.

  Then, as shown in FIG. 4 (a), the buckle 20 is directed to the umbilicus position 1a on the body surface of the person to be measured 1, and the belt member 13 is rotated clockwise, while the surface fastener (loop portion) 21b of the distal end portion 13b. Is affixed to the hook-and-loop fastener 21a of the buckle 20. Thereby, the belt member 13 can be wound around the abdomen 2 of the person to be measured 1 as shown in FIGS.

  Returning to FIG. 1, the back surface of the buckle 20 of the belt member 13 is provided with a first electrode 4 that contacts the umbilicus position 1 a on the body surface of the person 1 to be measured. The belt member 13 is fitted with a cursor member 22 slidable in the arrow direction a along the belt member 13, and the back surface of the cursor member 22 is positioned at a back position 1 b on the body surface of the person 1 to be measured. The 2nd electrode 5 which contacts is provided. The second electrode 5 can be adjusted in position by sliding to the back position 1b. A plurality of first and second electrodes 4 and 5 may be provided.

  The vicinity of the belly position 1c of the belt member 13 is formed wide, and a rectangular opening 13d extending in the longitudinal direction of the belt member 13 is formed in the wide portion 13c.

  As shown in FIG. 3, a flexible plastic plate 23 that can be fitted into the opening 13d of the belt member 13 with a margin is provided separately, and a pair of third electrodes 6a and 6b are provided at a predetermined interval on the plastic plate 23. Installed in. A gel that can be attached to the body surface of the person to be measured 1 with an adhesive force is adhered to the pair of third electrodes 6a and 6b. The pair of third electrodes 6a and 6b is formed by fitting the plastic plate 23 into the opening 13d of the belt member 13 and sticking the plastic plate 23 to the body surface of the measurer 1 with a gel. It comes in contact with the position 1c. An arrow mark b is printed on the plastic plate 23 between the pair of third electrodes 6a and 6b. The plastic plate 23 is sandwiched and held between the wide portion 13c with a clip or the like before being attached to the body surface of the measurer 1. In addition, a release sheet is attached to the gel attached to the pair of third electrodes 6a and 6b, and the release sheet is peeled off immediately before application.

  Here, the umbilicus position 1a is preferably in the vicinity of a position shifted from the true center by several centimeters in the circumferential direction because the first electrode 4 is unlikely to contact the body surface at the true center of the umbilical hole. Similarly, the back position 1b is preferably in the vicinity of a position shifted by several centimeters in the circumferential direction from the true center of the spine. Further, the flank position 1 c is a position near a position corresponding to approximately half the circumference of the belt member 3 between the first electrode 4 and the second electrode 5.

  A wire connecting terminal 24 is suspended from a lower edge portion of the opening 13d of the belt member 13 by a hanging strap 24a so as to be movable in the arrow direction a. The terminal 24 includes a first electrode 4 and a second electrode 5. Electric wires 25a and 25b are connected to each other. Moreover, the electric wires 25c and 25d of a pair of 3rd electrodes 6a and 6b are also connected, respectively. Furthermore, the electric wire 25e of the control part 7 installed separately from the belt member 13 is connected.

  Then, the controller 7 is operated to input physical information such as the waist length and sex of the person 1 to be measured, and a measurement start button or the like of the controller 7 is pressed. Thereby, the measuring means provided in the control unit 7 causes a current to flow between the first electrode 4 and the second electrode 5, and measures a voltage value generated between the pair of third electrodes 6a and 6b. Next, the fat amount of the abdomen of the person to be measured 1 is calculated based on the measured voltage value and the input physical information, etc. by the calculating means provided in the control unit 7, and the calculated fat amount is displayed on the display device. 8 is displayed.

  As shown in FIG. 2, the belt member 13 is printed with a scale 26 indicating the circumferential length of the belt member 13 from the first electrode 4 of the buckle 20 to the second electrode 5 of the cursor member 22. . The unit of the numbers 31, 32,... Of the scale 26 is cm. Therefore, for example, if the protrusion 22a of the cursor member 22 is at the position of numeral 38, it means that the circumferential length of the belt member 13 between the first electrode 4 and the second electrode 5 is 38 cm. From this, it can be visually confirmed that half of the abdomen circumference of the person to be measured 1 is about 38 cm and the total length of the abdomen circumference is about 76 cm.

  Further, as shown in FIG. 3, the inner edge of the opening 13 d of the belt member 13 corresponds to a length approximately half of the circumferential length of the belt member 13 between the first electrode 4 and the second electrode 5. A third electrode positioning scale 27 is printed at the position. At this time, the scale 27 points to a position that is half the distance from the first electrode 4 to each scale of the scale 26. In order to understand this relationship at a glance, the scale 27 is given the same numbers 31, 32,... As the corresponding scale 26. For example, if the projection 22a of the cursor member 22 is at the position of the numeral 38 of the scale 26, the arrow mark b is set to the third electrode of the opening 13d while the plastic plate 23 is fitted into the opening 13d of the belt member 13. Align with the number 38 on the positioning scale 27. In this state, the pair of third electrodes 6a and 6b are attached to the body surface of the measurer 1 with a gel together with the plastic plate 23.

  In the case of the belt type body fat measuring device as described above, the first electrode 4 and the second electrode 5 are installed integrally with the belt member 13. Therefore, when the person to be measured 1 winds the belt member 13 around the abdomen, the first electrode 4 and the second electrode 5 are moved to the umbilicus position 1a and back position 1b on the body surface of the person 1 to be measured by the winding force of the belt member 13. Come into contact.

  In contrast, the pair of third electrodes 6 a and 6 b come into contact with the plastic plate 23 by being attached to the flank position 1 c of the person 1 to be measured from the opening 13 d of the belt member 13.

  In other words, the pair of third electrodes 6 a and 6 b is simply attached to the flank position 1 c of the measurement subject 1 from the opening 13 d of the belt member 13 and brought into contact therewith. Therefore, even if the winding force of the belt member 13 is too strong, the belt member 13 is not strongly pressed against the abdomen 2.

  In this manner, the pair of third electrodes 6a and 6b can be installed on the belt member 13 so as not to affect the measurement accuracy.

  Further, by forming the rectangular opening 13d in the wide portion 13c of the belt member 13, when the belt member 13 is wound around the abdomen 2 and pulled, the tensile force acts on the wide portion 13c evenly. 13d is not twisted.

  Further, when the second electrode 5 is slid to the back position 1b, a scale 26 (for example, numeral 38) indicating the position of the second electrode 5 is memorized. Then, the pair of third electrodes 6 a and 6 b are attached to the flank position 1 c of the measurement subject 1 together with the plastic plate 23 in accordance with the scale 27 (for example, the number 38) having the same number. Since the positioning scale 27 of the opening 13d is formed at a position corresponding to half the circumferential length of the belt member 13 between the first electrode 4 and the second electrode 5, a pair of third The electrodes 6a and 6b can be accurately affixed to the flank position 1c of the measurement subject 1 at an intermediate position between the first electrode 4 and the second electrode 5.

  Further, since the scales 26 and 27 are scales of the circumferential length of the belt member 13 between the first electrode 4 and the second electrode 5, the entire circumferential length of the abdomen 2 of the person to be measured 1 can be easily measured. can do.

  Further, by attaching the pair of third electrodes 6a, 6b to the flexible plastic plate 23 at a predetermined interval, the interval between the pair of third electrodes 6a, 6b can be accurately maintained. Further, by attaching the gel to the pair of third electrodes 6a and 6b, the pair of third electrodes 6a and 6b can be easily and quickly attached to the body surface of the person 1 to be measured. It can be easily and quickly removed from the body surface. Furthermore, since the plastic plate 23 is flexible, it is easy to become familiar with the curvature of the body surface of the person 1 to be measured. The plastic plate 23 may be either transparent or opaque. However, when the plastic plate 23 is transparent, the plastic plate 23 can be attached to the body surface of the measurement subject 1 while seeing through the pair of third electrodes 6a and 6b.

  In the embodiment described above, the scales (marks) 26 and 27 are numbers (scale scales), but may be characters such as A, B, and C, or pictographs.

  The above embodiment measures the fat mass of the abdomen 2, and is particularly suitable for the measurement of visceral fat mass. However, if the signal processing of each electrode is performed, the subcutaneous fat mass can also be measured.
