As shown in Figure 6, the limb guide part 2 is composed of a detachable arm 23, a rotating arm 22 and a telescopic arm 21. One end of the detachable arm 23 is detachably connected to the main body part 1, and the other end is rotatably connected to the rotating arm 22. The rotating arm The other end of 22 is telescopically connected to the telescopic arm 21 .

The two functions of the limb guide part 2 here, one is retractable, which is adjusted for patients of different heights to find a suitable collection point to ensure the accuracy and precision of the collection; the other is bendable, which is for According to the degree of fatness and thinness of different patients, by bending, the electrode 4 can be more accurately fitted to the human skin, so that the collected data is more stable and accurate.

As shown in FIG. 7 , the electrode 4 includes a mounting base 41 and a collection head 42 . The mounting base 41 is installed on the limb guide part 2 , the chest guide part 3 and the main body part 1 , and the collection head 42 is detachably connected to the installation base 41 . Several dimples 426 are provided on the outside.

The mounting seat 41 protrudes outward to form a cylindrical protrusion 411, which protrudes outward to form an annular protrusion 412. The annular protrusion 412 surrounds the cylindrical protrusion 411 in the middle position, and there is a gap between the two. In the first cavity 414 , the outer side of the annular protrusion 412 protrudes radially outward to form a plurality of positioning protrusions 413 .

The collection head 42 is formed with a first installation hole 421 that matches the cylindrical protrusion 411, and an annular installation hole 422 that matches the annular protrusion 412.
