In addition, in order to reduce the wearing and tearing of flexible member 26 pairs of band bodies 10 when being provided with flexible member 26, and electrode 2 is smoothly moved in the slit 31 of electrode position adjustment structure 30, on cylinder 23, electrode pads 210 can be set between flexible member 26 and band body 10.In addition, on cylinder 23, outside band body 10, also electrode pads 210 should be set, pad collar 211 is set in pad draw-in groove 25 simultaneously, or electrode pads 210 and pad collar 211 also can not be set, and directly electrode collar 200 (not shown) is directly set in pad draw-in groove 25, depart from from band body 10 to prevent columnar electrode 20 and drop out.
In addition, except the columnar electrode near chest intermediate recess region 110, if the electrode 2 that other positions use also is columnar electrode, also can the suitable flexible member 26 of installation length between its electrode contact 21 and band body 10, such as hollow spring, can provide good contact pressure to testee's skin to make electrode contact 21.
Should be appreciated that, the specific embodiment of the present invention is for the present invention will be described but not limit.
Such as, for the weight of weight 5, can make to be with the electrode 2 on shape device 1 effectively just passable with the contact skin of testee by being arranged on as long as it will be understood by those skilled in the art that, the weight that such as 200 to 1000 grams of materials have.Although larger weight can improve the stability of band shape device, make electrode more well with the contact skin of testee, also can consume operator when using more physical, it is unfavorable that this especially may cause women operator.
And for example, special restriction is not done to the connected mode of belt body 51 and band body 10, but preferably adopt the movable connection method that can conveniently connect and disconnect, such as connected by modes such as slide fastener, the fasteners that cooperatively interacts, to make band body 10 can connect different fixtures to be suitable for different fixed forms, the weight 5 being also convenient for changing Different Weight is suitable for different operators.
And for example, are a kind of smooth metal contact with arc convex for the electrode contact 21 shown in columnar electrode 20, Fig. 3, Fig. 4 and Fig. 8, but common sucked type contact is also fine.
And for example, the electrode retainer 32 in the present invention forms with band body 10, but also can be that the mode of fixing the electrode retainer that closes with slit 31 matching form in the inner surface of band body 10, outer surface and interlayer is formed.
And for example, and electrodes 2 all on non-band shape device 1 all need use columnar electrode.Such as, except near the electrode in chest intermediate recess region 110, the electrode set by other positions also can be the very short other forms of electrode of length, such as shim-like electrode.
The present invention has significant advantage.This band shape device is cheap, easy to use.Because there is elongated electrode position adjustment structure, this band shape device is applicable to the testee of the various bodily form.The orientation of slit ensure that the very accurate anatomy location of electrode, and electrode retainer can avoid electrode to depart from the position of setting easily.Near the umbilicate region of chest, electrode length is slightly long and use flexible member provides pressure to electrode contact, makes the skin in electrode contact energy reliable contacts chest intermediate recess region.The most important thing is, owing to adopting gravity to fix this band shape device, this makes the operation of fixing band shape device become very easy, is particularly conducive to the occasion needing frequently to carry out ECG measurement for a long time.
