Embodiments of the present invention

The technical solution of the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention.

As shown in Figures 1 and 2, an integrated ECG acquisition device includes a main body part 1, a limb guide part 2, a chest guide part 3 and an electrode 4.

There are four limb guide parts 2, one end of which is connected with the main body part 1.

The breast guide part 3 is connected to the main body part 1 at one end.

There are several electrodes 4, which are respectively arranged on one end of the limb guide part 2, the main body part 1 and the chest guide part 3.

As shown in Figure 3, the limb guide part 2 and the chest guide part 3 and the main body part 1 are connected in a detachable manner.

Such a detachable structure is convenient for storage, packaging and transportation, and at the same time, it is convenient for the main body part 1 to be connected with the lead pin electrode, so that the functions are diversified and the use is more flexible.

As shown in Fig. 4, the limb guide part 2 is provided with a circular plug-in button. When the limb guide part 2 needs to be removed from the main body part 1, the button needs to be pressed.

As shown in FIG. 5, the main body part 1 may also be connected to the lead pin electrode 5.

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 other end of 22 is telescopically connected with the telescopic arm 21.

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

As shown in Figure 7, the electrode 4 includes a mounting base 41 and a collecting head 42, the mounting base 41 is mounted on the limb guide part 2, the chest guide part 3 and the main body part 1, and the collecting head 42 is detachably connected to the mounting base 41. A number of pits 426 are provided on the outside.

The mounting seat 41 protrudes outward to form a cylindrical protrusion 411, and 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 collecting head 42 is formed with a first mounting hole 421 that is adapted to the cylindrical protrusion 411, and a circular ring-shaped mounting hole 422 that is adapted to the circular ring-shaped protrusion 412 is formed.

The design of the pit 426 forms some tiny suction cups, so that when the electrode 4 is in contact with the human body, a tiny negative pressure is formed locally, which increases the stability of the contact between the electrode 4 and the human body and ensures the stability and accuracy of information measurement.

The detachable connection of the collecting head 42 and the mounting seat 41 makes the replacement of the collecting head 42 convenient. Since the collecting head 42 has a short life, it needs to be replaced in time, and the detachable connection form is convenient to replace.

Regarding the connection between the collecting head 42 and the mounting seat 41, the first annular protrusion 424 is inserted into the first cavity 414, and is in a compressed state, which serves as a fixing function to prevent the collecting head 42 from falling off.

The first annular protrusion 424 is divided into two parts by the opening 425, which provides sufficient deformation space to make it easier to insert into the first cavity 414.

The cooperation of the positioning protrusion 413 and the positioning groove 423 prevents the collecting head 42 and the mounting seat 41 from rotating loose during use.
