In addition, since the upper and lower front fixing portions 8a are fixed to the outer fastening member 7, the second belt 4R is in a stable state with the first belt 4L as compared with the case where only one front fixing portion 8a is provided. can be fixed in the proper position. Furthermore, since the total width of the front fixing part 8a is set to be smaller than the width of the main fixing part 8b, it is possible to reduce the force required to separate the front fixing part 8a from the outer retaining body 7. Since a portion that is not attached to the outer fastening member 7 is formed between the outer fastening members 8a, the front fixing portion 8a can be easily peeled off from the outer fastening member 7. As shown in FIG.

If the front fixing portion 8a is formed inside the width region in the vertical direction of the main fixing portion 8b, the width of the front fixing portion 8a can be reduced as necessary so that the front fixing portion 8a can be attached to the outside. Since the tightening area can be reduced when temporarily fixed to the body 7, the tightening force can be optimized and the wearing comfort can be improved.

When the main fixing portion 8b is formed continuously with the front fixing portion 8a, the end of the front fixing portion 8a connected to the main fixing portion 8b is fastened to the outer fastening body 7 together with the main fixing portion 8b, The fixing force when the belt body 1 is worn around the chest can be improved.

If the main fixing portion 8b and the front fixing portion 8a are formed separately in the longitudinal direction of the belt body 1, the attachment and detachment operations of the front fixing portion 8a and the main fixing portion 8b with respect to the outer fastening member 7 are independent. can be done. Therefore, in a state where only the front fixing portion 8a is temporarily fixed to the outer fastening member 7, the positions of the electrocardiographic electrodes 36 are confirmed, or the degree of tightness of the belt body 1 is checked, and then the main fixing portion 8b is externally fastened. It can be permanently fixed by being attached to the attachment body 7 . In addition, since the presence of the gap 55 in the separated portion allows confirmation that the entire main fixing portion 8b has been separated from the outer fastening body 7, the front fixing portion 8a can be separated from the outer fastening body 7 with a smaller force thereafter. As compared with the case where the main fixing portion 8b and the front fixing portion 8a are separated from the outer fastening member 7 at once, the second belt 4R can be easily removed from the first belt 4L.

When the front fixing portion 8a is formed outside the vertical width region of the main fixing portion 8b, a large portion that is not fastened to the outer fastening body 7 is formed near the center of the width of the main fixing portion 8b. Therefore, the main fixing portion 8b can be easily peeled off from the outer fastening member 7. As shown in FIG.

A belt body 1 is composed of a first belt 4L and a second belt 4R, and an electrode unit 2 having a plurality of electrocardiographic electrodes 36 and a pair of upper and lower non-slip tapes 12 are provided on the skin contact surface side of the first belt 4L. is provided, and a pair of upper and lower anti-slip tapes 25 are provided on the skin contact surface side of the second belt 4R, and the anti-slip tapes 12 and 25 of the first and second belts 4L and 4R are attached to the first and second belts. 2, the entire non-slip tapes 12 and 25 can be brought into close contact with the skin surface from the back to the sides of the chest when the belt body 1 is worn around the chest. As a result, it is possible to reliably prevent the belt body 1 from slipping up and down, and to improve the close contact feeling of the belt body 1.例文帳に追加

The electrode unit 2 held by the electrode holding portion 11 of the belt body 1 is composed of a base mat 34, a plurality of electrode mats 35, a plurality of electrocardiographic electrodes 36 fixed to each electrode mat 35, and the like. If the base mat 34 between the mats 35 is provided with the bending promoting portion 40, when the belt body 1 is worn around the chest, the bending promoting portion 40, which is more likely to be curved and deformed than other parts, is placed around the chest. Since it can be curved along the skin surface, each electrode mat 35 can be reliably brought into close contact with the skin surface.

If the bending promoting portion 40 provided in the base mat 34 is composed of any one of a notch portion, one or more openings, a thin portion, and a low density portion, the bending strength of the base mat 34 in the bending promoting portion 40 can be reduced, the bending of the first belt 4L can be facilitated, and the fit when the belt body 1 is worn around the chest can be improved.

The electrode holding part 11 is formed by the belt body 1 and the pocket body 16 to form a pocket into which the electrode unit 2 can be put in and taken out, and the pocket body 16 has a plurality of electrode windows through which the respective electrocardiographic electrodes 36 are individually exposed. 17 is opened and each electrocardiographic electrode 36 is accommodated in the pocket main body 16, the skin-contacting surface side of each electrocardiographic electrode 36 is exposed from each electrode window 17, and the skin-contacting surface side is detachable from the pocket main body 16.

In the inner fastening body 8 of FIG. 12(a) according to the second embodiment, similarly to the inner fastening body 8 of the first embodiment, the front stage fixing portion 8a is formed at the vertical width center of the main fixing portion 8b. However, it differs from the inner fastening member 8 of the first embodiment in that the main fixing portion 8b and the front fixing portion 8a are formed separately in the longitudinal direction of the belt body 1. As shown in FIG. By disposing the main fixing portion 8b and the front fixing portion 8a separately in this manner, a gap 55 is formed between the both 8a and 8b so that the outer fastening member 7 is not attached. Since other parts are the same as those of the first embodiment, the same reference numerals are given to the same members, and the description thereof will be omitted. The same applies to each of the following embodiments.

As described above, when the main fixing portion 8b and the front fixing portion 8a are arranged separately through the gap 55, the front fixing portion 8a and the main fixing portion 8b can be attached to and detached from the outer fastening body 7 independently. It can be carried out. Therefore, after confirming the positions of the electrocardiographic electrodes 36A, 36B, and 36C or checking the degree of tightness of the belt body 1 in a temporarily fixed state in which only the front fixing portion 8a is fixed to the outer fastening member 7, the main fixing portion is fixed. 8b can be attached to the outer fastening member 7 for permanent fixation. In addition, since the presence of the gap 55 makes it possible to confirm that the entire main fixing portion 8b has been separated from the outer fastening member 7, the front fixing portion 8a can be separated from the outer fastening member 7 with a smaller force thereafter. , the operation of peeling the second belt 4R from the first belt 4L can be performed more easily than when the main fixing portion 8b and the front fixing portion 8a are peeled off from the outer fastening member 7 at once.

In the inner fastening body 8 of FIG. 12(b) according to the third embodiment, the front stage fixing portion 8a is provided below the width center of the main fixing portion 8b and near the width center of the main fixing portion 8b. In this way, when the front stage fixing portion 8a is provided near the width center of the main fixing portion 8b, the second belt 4R is temporarily fixed to the first belt 4L in the same manner as the electrocardiographic signal measurement belt of the first embodiment. In this state, since the vicinity of the center of the vertical width of the belt body 1 can be tightened, the main fixing portion 8b can be fixed to the outer fastening member 7 in good balance.

In the inner fastening body 8 of FIG. 12(c) according to the fourth embodiment, the main fixing portion 8b is formed separately into a square upper portion 8b1 and a rectangular lower portion 8b2.

Attachment/detachment of the second belt 4R to/from the first belt 4L can be performed more easily.

In the fifth embodiment, as shown in FIG. 12(d), the front fixing portion 8a of the inner fastening body 8 is formed continuously with the upper end and the lower end of the main fixing portion 8b. Further, the total width dimension of the front stage fixing portion 8a is set smaller than the width dimension of the main fixing portion 8b. By providing the front fixing portion 8a at two locations above and below the main fixing portion 8b in this manner, the fastening force when the front fixing portion 8a is temporarily fixed to the outer fastening member 7 is increased to about twice that of the second fixing portion 8b. The belt 4R can be firmly temporarily fixed to the first belt 4L. Further, since the upper and lower front stage fixing portions 8a are fixed to the outer fixing member 7, the second belt 4R can be fixed to the first belt 4L in a stable state and at an appropriate position. Incidentally, when only one front fixing portion 8a is provided, the second belt 4R is likely to be obliquely fastened to the first belt 4L. Furthermore, since the total width of the front fixing portion 8a is set smaller than the width of the main fixing portion 8b, and the front fixing portion 8a is provided at two upper and lower portions of the main fixing portion 8b, the front fixing portion 8a can be attached to the outer fastening body. In addition to reducing the force when peeling off from 7, a portion that is not attached to the outer fastening body 7 is formed between the upper and lower front fastening parts 8a, so the front fastening part 8a can be easily removed from the outer fastening body 7. Can be stripped.

In the electrocardiographic signal measurement belts of the second to fifth embodiments, the front fixing portion 8a is formed inside the vertical width region of the main fixing portion 8b, so that the width dimension of the front fixing portion 8a is not required. By reducing the size accordingly, the tightening area when the front fixing portion 8a is temporarily fixed to the outer fastening member 7 can be reduced. As a result, it is possible to optimize the tightening force and improve the wearing comfort. Moreover, the material cost can be reduced by the amount of reduction in the width dimension of the front stage fixing portion 8a.

In the electrocardiographic signal measurement belts of the third to fifth embodiments, as in the first embodiment, the front fixing portion 8a is formed continuously with the main fixing portion 8b. It can improve the fixing force when worn around the chest.
