[0002]

2. Description of the Related Art As a grip portion of this kind of health management guideline advice device, there is one as shown in FIG.
The pair of grip portions 100, 110 have a cylindrical shape, and each of the grip portions 100, 110 has a constant current application electrode 101, 1 along the axial direction.
11 and voltage detection electrodes 102 and 112, and caps 103 and 113 are put on electrode ends. The grip portions 100 and 110 are joined in a straight line by a connector 120, and a connector 121 for connecting the apparatus main body is connected to the connector 120 by a cable 122.

The grip portion is used by extending the arm straight forward in a direction substantially perpendicular to the body, and holding the grip portions 100 and 110 with left and right hands (see FIG. 4). FIG. 17 shows a state where the grip portion 100 is gripped with the left hand LH. At this time, the four fingers of the left hand LH other than the thumb contact the constant current application electrode 101, and the thumb contacts the voltage detection electrode 102.

[0004]

However, the apparatus provided with the grip portion having the above structure has the following problems. In the electrode mounting position of the basic measurement method for measuring between the right wrist and the ankle shown in FIG. 18, when the constant current application electrode 130 and the voltage detection electrode 131 are mounted on predetermined portions of the right wrist, the wrist projection bone (ulnar bone) Since there is a marker for measuring the impedance measurement site of the body like the stalk 132)
While the influence of the measurement position deviation is small, when the measurement is performed by gripping the grip portion as shown in FIG. 16, the measurement is performed by simply gripping the cylindrical grip portion with the palm. Depending on the size, the thickness of the palm, etc., the measurement position may be displaced. The size of the palm varies depending on gender, age, and the like, which is also a factor of the influence of the measurement position deviation. In particular, for a person with a large palm with a long finger like a man and a person with a small palm like a woman, a plurality of current application conduction paths may occur depending on the electrode structure, and the conduction paths may differ depending on the size of the hand. is there. In the basic measurement method shown in FIG.
Is attached to the back of the hand near the base of the index finger. If the constant current drive circuit is not secured, the capability of the constant current drive circuit (the upper limit of the constant current drive load) may be reduced, and a constant current application error may occur. In particular, in the case of a grip portion in which a constant current application electrode is attached to a fingertip or the like, since the finger joint and the finger portion are thin, the resistance increases, and there is a possibility that a constant current application error may occur. Also, due to differences in the current flow paths, there is a possibility that problems may arise in the consistency of the measurement method with the basic measurement method shown in FIG. 18, and in the reproduction and stability of the measurement. Also in the voltage detection electrode, as the distance from the back of the wrist in the basic measurement method in FIG. 18 and the distance from the main current path increase, a problem may occur in the measurement method consistency with the basic measurement method and a measurement error may occur. There is. If both electrodes are made of a thick metal plate such as SUS or copper, the heat capacity will be large. Capillary atrophy on the skin surface of the part may affect the measured resistance value. In many cases, the shape of the electrode having good fit to the palm is a complicated shape, and it may be quite difficult to process a corrosion-resistant metal plate such as SUS to achieve good fit.

However, in the following, the vertical grip is taken up and only the grip on the right hand side is shown in principle, but the horizontal grip may have the same structure, and the grip on the left hand side is symmetrical. Needless to say, it is necessary to do so. Note that the same elements are denoted by the same reference numerals.

First, a grip portion 70 shown in FIG.
A is a basic type (see FIGS. 1 and 2), and includes a constant current application electrode 71 in an upper portion, a voltage detection electrode 72 in a lower portion, and a separating portion (non-electrode portion) for separating both electrodes 71 and 72. A spacing portion 73, a positioning flange 74 at the upper end, and a positioning flange 75 at the lower end. When such a grip portion 70A is gripped by hand, the left hand LH shown in FIG.
In the palm surface, a shaded area a from the index finger to the thumb is a contact surface with the constant current application electrode 71, and a shaded area b including the ring finger and the little finger to the palm bank c is the voltage detection electrode 7.

It is important that the size is such that the thumb and the index finger are located when the A is gripped. The axial width of the separating portion 73 is approximately equal to the width d of the middle finger, and it is important that the middle finger is located at the separating portion 73 when the grip portion 70A is gripped.
It is important that the axial width of the voltage detection electrode 72 is a dimension that can cover most of the palm-side bank, or a dimension that can ensure contact with the palm-bank near the wrist.

The grip portion 70B shown in FIG. 6 has a convex portion 76 as a finger guide for positioning a finger when grasping. The convex portion 76 is used for positioning the index finger, the index finger and the middle finger. belongs to. That is, the grip part 70B is gripped such that the index finger is located on the constant current application electrode 71 above the convex part 76, and the convex part 76 is located between the index finger and the middle finger. It is preferable that the finger guide is limited to the index finger, the middle finger, or the index finger and the middle finger, and does not restrict the grip position of the other ring finger or the little finger from the viewpoint of measurement accuracy and the like.

The grip portion 70C shown in FIG. 7 has a concave portion 77 as a finger guide for finger positioning. This recess 77 functions as a guide groove for the middle finger when grasping,
It is shared with the separation part 73 of both electrodes 71 and 72. Since the grip portion 70C is cylindrical and vertically symmetrical like the grip portion 70A of FIG. 5, the gripping position is not limited by enabling both electrodes 71 and 72 to rotate, and from which direction. Even if the user grips, the same contact is made, and no grip error occurs.

A grip portion 70D shown in FIG. 8 has a structure corresponding to the grip portion 70B shown in FIG. here,
The portion facing the palm bank from the lower part of the voltage detection electrode 72 to the lower flange 75 is a projection 78 that protrudes in a curved shape. When the grip portion 70D is grasped, the palm bank portion surely contacts the protruding portion 78.

The grip portion 70E shown in FIG. 9 has a protruding portion 79 which has a longer overall length in the axial direction and which protrudes in a curved shape from the separating portion 73 to the lower flange portion 75. When the grip portion 70E is gripped, not only the palm bank portion but also the wrist portion reliably contact the protruding portion 79. A grip part 70F shown in FIG. 10 is a modified example of the grip part 70E of FIG. 9, and has a voltage detection electrode 72 provided only on the contact surface with the palm. Of course, also in this case, the grip 70
When F is grasped, the palm bank and the wrist are securely brought into contact with the voltage detection electrode 72.

The grip part 70H shown in FIG. 7 has tapered expansion parts 80 and 81 in the lower half and the upper half. By the way, each of the grip portions 70A to 70H has a cylindrical shape, and its diameter is set to about 30 to 45 mm. If the grip is cylindrical, a grip shift in the rotation direction may occur depending on how the grip is held. To prevent the grip in the rotation direction, as shown in FIG.
I may have an eccentric cylindrical shape, or the grip portion 70J may have an elliptical cylindrical shape as shown in FIG. Each of the grip portions 70I and 70J has a finger guide groove 82 for the index finger, and when grasping the index finger, the finger guide groove 8 is provided.
Position 2

Further, the grip portion 70K shown in FIG.
It is cylindrical, but the diameters of the upper half and the lower half are different. That is, the diameter φ2 of the voltage detection electrode 72 is set to be larger than the diameter φ1 of the constant current application electrode 71. In this case, the palm bank portion surely contacts the large-diameter voltage detection electrode 72. Also in this grip portion 70K, both electrodes 71 and 72 may be rotatable, respectively, to prevent the gripping displacement in the rotation direction.

In the above-described embodiment, the positioning flanges are provided at the upper end and the lower end of the grip, but only one of them may be provided. In addition, although a convex portion or a concave portion is provided as a finger guide for finger positioning, a finger guide having an uneven shape may be used.
