Additionally, for providing better contact force, a flexible member 26 can be arranged between electrode contact 21 and band body 10 to provide an elastic pressure to electrode contact 21.This makes in the case of band body 10 is flattened, and band body 10 can provide an enough elastic force to make electrode contact 21 can contact the most well with the skin of testee by this hollow spring to electrode contact 21.
This flexible member 26 preferably hollow spring, can be set on cylinder 23 and be arranged between electrode contact 21 and band body 10 by this hollow spring.It is highly preferred that the diameter of this hollow spring is change, such as in the middle of maximum, two ends taper into, and so, when compressing this hollow spring, the turn of minor diameter can be in the turn of indentation major diameter so that the length of compression rear spring can be extremely short.So, in the case of hollow spring has same long original length, it is provided that longer Adjustable Range.
In addition, in order to reduce the flexible member 26 abrasion to band body 10 in the case of being provided with flexible member 26, and make electrode 2 smoothly move in the slit 31 of electrode position adjustment structure 30, electrode pads 210 can be set between flexible member 26 and band body 10 on cylinder 23.In addition, on cylinder 23, electrode pads 210 also should be set outside band body 10, pad collar 211 is set in pad draw-in groove 25 simultaneously, or electrode pads 210 and pad collar 211 can also be not provided with, and directly electrode collar 200 (not shown) is directly set in pad draw-in groove 25, drop out to prevent columnar electrode 20 from departing from from band body 10.
In addition, except the columnar electrode near chest intermediate recess region 110, if the electrode 2 that other positions use also is columnar electrode, can also the suitable flexible member of installation length 26 between its electrode contact 21 and band body 10, the most hollow spring, so that electrode contact 21 can provide good contact pressure to testee's skin.
Fig. 9 illustrates the structure of the columnar electrode 20 of another kind of improvement.The length of its middle column body 23 is the shortest, is not integrally formed with electrode contact 21 or fixing, only acts the effect being fastened on electrode receiving portion 33.Flexible member 26 one end is fixed with electrode contact 21, such as pass through to be welded and fixed or be arranged on the installing hole on electrode contact 21 to fix, one end snare is positioned on the pad draw-in groove 25 inside band body 10 on cylinder 23, utilizes the electric conductivity of flexible member 26 to transmit electrode signal.
It should be understood that the detailed description of the invention of the present invention is for the present invention will be described rather than is defined.
Such as, for the weight of weight 5, as long as it will be understood by those skilled in the art that so that the electrode 2 that is arranged in belt-shaped device 1 is effectively the most permissible with the contact skin of testee, the weight that such as 200 to 1000 grams materials are had.Although bigger weight can improve the stability of belt-shaped device, make electrode more well with the contact skin of testee, but it is the most physical also to consume operator when using, and it is unfavorable that this is particularly likely to cause women operator.
And for example, the connected mode of belt body 51 with band body 10 is the most particularly limited, it is preferable to employ the movable connection method that can be conveniently connected and disconnected from, such as connected by modes such as slide fastener, the fasteners that cooperates, so that band body 10 can connect different fixtures to be suitable for different fixed forms, it is also convenient for changing the weight 5 of Different Weight to be suitable for different operators.
And for example, for columnar electrode 20, the electrode contact 21 shown in Fig. 3, Fig. 4 and Fig. 8 is a kind of smooth metal contact with arc convex, but common sucked type contact is also possible.
And for example, the electrode retainer 32 in the present invention is to form with band body 10 but it also may be that the mode fixing an electrode retainer closed with slit 31 matching form in inner surface, outer surface and the interlayer of band body 10 is formed.
And for example, not all of electrode 2 is required for using columnar electrode in belt-shaped device 1.Such as, except near the electrode in chest intermediate recess region 110, the electrode set by other positions can also be the electrode of the shortest other forms of length, such as shim-like electrode.
The present invention has significant advantage.This belt-shaped device is cheap, it is simple to use.Because there being elongated electrode position adjustment structure, this belt-shaped device is applicable to the testee of the various bodily form.The orientation of slit ensure that the exactly accurate anatomy location of electrode, and electrode retainer can avoid electrode to deviate the position of setting easily.Near the umbilicate region of chest, electrode length is slightly long and uses flexible member to provide pressure to electrode contact, makes the skin in electrode contact energy reliable contacts chest intermediate recess region.Most importantly, due to use gravity to fix this belt-shaped device, this makes the operation of fixing belt-shaped device become extremely easy, is particularly conducive to the occasion needing frequently to carry out ECG measurement for a long time.
