the electrocardiograph 1000 may include a stretchable upper limb portion 10, a stretchable thoracic cavity portion 20, and a stretchable lower limb portion 30.
The telescopic upper limb part 10 is used for collecting electrocardiosignals of a preset part of an upper limb of a human body through the electrode plate 40 arranged on the telescopic upper limb part 10. The telescopic upper limb 10 comprises a first connection part 11 and a collecting cartridge 60. The arm generally includes a left arm and a right arm, so two first connecting portions 11 are usually provided, and the two first connecting portions 11 are symmetrically provided. The two first connecting portions 11 are disposed along the horizontal direction in different directions with the position of the collecting box 60 as the center, and may be disposed along the direction forming different angles with the horizontal direction, which is not limited herein. That is, the two first connecting portions 11 extend from the point where they meet the collecting box 60, and at least one first stretching structure 12 is formed during the extension until the distal electrode sheet 40 is reached. The two first connecting portions 11 may have the same or different structures, and the present application is not limited thereto. Each of the first connection portions 11 includes a signal transmission portion 50 and at least one electrode pad 40 disposed corresponding to the signal transmission portion 50. Wherein the signal transmitting portion 50 comprises at least one first elongated structure 12. The signal transmission part 50 is formed with at least one first stretching structure 12, and the first stretching structure 12 can not only be horizontally stretched, but also can move up and down, and can be restored to the original position after the use is completed, so that the electrocardiosignal acquisition device can be adapted to users with different arm lengths to acquire electrocardiosignals, and is convenient to store. It should be noted here that the number of the first connecting portions 11 is not limited to two, and the arrangement manner of the first connecting portions 11 is not limited to the above-mentioned arrangement manner, for example, the first connecting portions 11 may also be arranged at an angle with the horizontal line. At least one signal transmission unit 50 of the plurality of signal transmission units 50 corresponding to the plurality of first connection units 11 is provided with a first stretching structure 12, which is not limited in the present application. Illustratively, one first tensile structure 12 may be provided on both 50.
Illustratively, when the user a uses the first connecting part 11, the extension length is 13 cm; the height of the user B is higher than that of the user A, and the arm of the user B is longer than that of the user A; b user, the extended length of the first connecting portion 11 is 15cm when in use. After the user A finishes the electrocardiographic acquisition, the horizontal lengths of the two signal transmission parts 50 can be recovered to 10cm after the two electrode plates 40 of the upper limb part 10 are taken down.
The signal transmission part 50 includes a substrate 51 and a plurality of conductive lines 52, and the plurality of conductive lines 52 may be printed on the substrate 51 by using a composite paste such as conductive silver paste, conductive carbon paste, conductive copper paste, silver-clad copper paste, or the like. The plurality of lead lines 52 and the metal layer 43 of the electrode sheet 40 may be encapsulated by the printing method. As shown in fig. 3, the substrate 51 includes a first encapsulation layer 511, a first shielding layer 512, a second base material layer 513, an insulating layer 514, a second shielding layer 515, and a second encapsulation layer 516. The sequence close to the skin of the human body is as follows: the first encapsulation layer 511-the first shielding layer 512-the second substrate layer 513-the conductive line 52-the insulating layer 514-the second shielding layer 515-the second encapsulation layer 516. The materials selected for the first packaging layer 511 and the second packaging layer 516 can be medical-grade skin-friendly materials, which are soft and comfortable and can improve the use experience of users. The material of the second substrate layer 513 may be one of a polyester film, a polyimide film, a silicone film, and the like. The plurality of lead lines 52, the electrode sheet 40, the first shielding layer 512, and the second shielding layer 515 are integrated by a printing process using printing paste of composite paste such as conductive silver paste, conductive carbon paste, conductive copper paste, silver-clad copper paste, or the like. The insulating layer 514 may be made of a resin material such as acrylate or urethane. The plurality of lead wires 52 are packaged in the substrate 51, so that external noise signal interference can be avoided, and the transmission quality of the electrocardiosignals is improved.
As shown in fig. 4, the electrode sheet 40 is attached to the skin of a human body to collect an electrocardiographic signal. The electrode sheet 40 includes a metal layer 43, a first substrate layer 44, a conductive hydrogel 42, a backing 45, and a release sheet 41. The sequence from being close to the skin of the human body to being far away from the skin of the human body is as follows: release sheet 41-conductive hydrogel 42-metal layer 43-first substrate layer 44-backing 45. The release sheet 41 is used for protecting the conductive hydrogel 42; the conductive hydrogel 42 can be attached to human skin to collect electrical signals on the surface of the skin; the metal layer 43 transmits the electrical signal collected by the conductive hydrogel 42 to the corresponding lead wire 52; the first substrate layer 44 provides a substrate for the metal layer 43, and the backing 45 can serve for protection on the one hand and for adhesion and fixing on the other hand. When the electrode plate 40 is used, the release sheet 41 is removed to expose the conductive hydrogel 42; the conductive hydrogel 42 is then placed in contact with the human skin and the backing 45 is adhesively secured to the human skin.
The collecting box 60 comprises a lead wire interface, a power signal interface and a shielding interface; the lead wire interface is connected with each lead wire; the power signal interface is connected with the power signal transmission line; the shield interface is coupled to the first shield layer 512 and/or the second shield layer 515. The collecting box 60 transmits the electrocardiosignals transmitted by the electrode plate 40 through the lead wire 52 to the electrocardiograph.
Optionally, the width of the first connection portion 11 ranges from 0.2 mm to 20mm, and the inner bending diameter 70 of the first stretching structure 12 is set in a first preset proportion to the width of the first connection portion 11.
Optionally, the ratio of the first preset ratio ranges from 0.1 to 10.
Because the first connecting portion 11 of the retractable upper limb portion 10 is disposed in the horizontal direction, the positions of the two arms of different users may be different during the usage of the electrocardiograph electrode 1000, for example, the two arms of the user a are in the horizontal extension state, and the two arms of the user B are in the vertical extension state; moreover, for users with different heights and weights, the lengths of the arms of the users are different, and the collection points of the electrocardiograph electrode 1000 are also different, so that the frequency of the stretching operation of the first stretching structure 12 is relatively high. Then, in order to avoid that at least one first stretching structure 12 arranged in the telescopic upper limb part 10 is torn and damaged in the frequent stretching process, the wider the stretching strength is, the larger the inward bending diameter 70 is, the wider the width of the first stretching structure 12 is, and the larger the inward bending diameter 70 of the first stretching structure 12 is, so as to achieve the technical effects of improving the stretching strength of the first connecting part 11, avoiding tearing, and prolonging the service life of the electrocardio-electrode 1000. Further, the first tensile structure 12 may be any one of an S-type structure, a U-type structure, a W-type structure, an M-type structure, and an N-type structure.
As shown in fig. 1, the electrocardio-electrode further comprises a telescopic thoracic cavity 20, wherein the telescopic thoracic cavity 20 is used for acquiring electrocardio-signals of a predetermined part of the thoracic cavity of a human body through an electrode plate 40 arranged on the telescopic thoracic cavity 20. The collapsible chest portion 20 is positioned based on the position of the human heart. The collapsible chest portion 20 includes a second connecting portion 21.
Illustratively, the number of the second connecting portions 21 may be three, and two of the three second connecting portions 21 may be symmetrically disposed about a center line of the position of the collecting box 60. And the two second connecting portions 21 which are symmetrically arranged are inclined downwards by 30 degrees from the horizontal plane, (or have different orientations, which is not limited herein), and at least one second stretching structure 22 is correspondingly arranged on the two second connecting portions 21. The two symmetrically arranged second connecting parts 21 can have the same structure or different structures; as shown in fig. 1, the stretchable thoracic cavity 20 is disposed based on the position of the heart of the human body, and the heart of the human body is located on the left side of the human body, so that when the electrocardiographic signal of the human body is collected, the electrocardiographic signal of the heart is mainly collected, the second connecting portion 21 is further provided with one second connecting portion 21 in addition to the two second connecting portions 21 symmetrically disposed, and the second connecting portion 21 is located on one side of the left ventricle and is disposed close to the lower limb portion, and has a certain distance from the other two second connecting portions 21. Therefore, the electrocardiosignal of the heart position can be better acquired, and a more accurate electrocardiogram can be obtained. The number of the second connection portions 21 is not limited to three, and may include a plurality of second connection portions 21, and the arrangement manner of the second connection portions 21 is not limited to the above arrangement manner, as long as a desired electrocardiographic signal can be acquired, which is not limited in the present application.
Each of the second connection portions 21 includes a signal transmission portion 50 and at least one electrode pad 40 disposed corresponding to the signal transmission portion 50. The signal transmission portions 50 may each include at least one second stretching structure 22, any two of the signal transmission portions 50 may include at least one second stretching structure 22, and any one of the signal transmission portions 50 may include at least one second stretching structure 22, which is not limited herein. For example, only one second stretching structure may be provided on the signal transmission section of the second sub-connection section other than the two symmetrically provided second sub-connection sections.
It should be noted that the structures of the signal transmission part 50 and the electrode plate 40 in the stretchable thoracic cavity part 20 are the same as those of the signal transmission part 50 and the electrode plate 40 in the stretchable upper limb part 10, and are not described herein again.
Optionally, the width of the second connection portion 21 ranges from 0.2 mm to 20mm, and the incurved diameter 70 of the second stretching structure 22 and the width of the second connection portion 21 are set in a second preset ratio.
Optionally, the ratio of the second preset ratio ranges from 0.1 to 10.
Since the position of the human heart is relatively fixed and does not shift according to the change of the human body shape, and the plurality of second connecting portions 21 are provided, in the process of performing electrocardiographic acquisition on the human heart through the electrode sheet 40 provided in the telescopic chest portion 20, the frequency of stretching operation performed on the second stretching structure 22 is relatively low, so that the width of the second connecting portion 21 can be set to be smaller than that of the first connecting portion 11, and the inner bending diameter 70 of the corresponding second stretching structure 22 is also smaller than that of the first stretching structure 12. The corresponding stretching requirement can be met, the tearing is avoided, and resources can be saved. Of course, the width of the second connection portion 21 may be the same as the width of the first connection portion 11, and the inner bending diameter 70 of the second stretching structure 22 may also be the same as the inner bending diameter 70 of the first stretching structure 12, so that the tensile strength of the entire electrocardiograph electrode 1000 can be further improved, the electrocardiograph electrode 1000 is prevented from being torn, and the service life of the electrocardiograph electrode 1000 is prolonged.
As shown in fig. 1, the electrocardiograph electrode further includes a telescopic lower limb 30, and the telescopic lower limb 30 is used for acquiring electrocardiograph signals of a predetermined portion of the lower limb of the human body through an electrode plate 40 disposed on the telescopic lower limb 30.
The telescoping lower limb 30 is set based on the position of the human leg. The telescopic lower limb part 30 comprises a third connecting part 31, and the third connecting part 31 can comprise two parts; the two third connecting portions 31 may be symmetrically disposed about a center line of the position of the collecting box 60. And the two third connecting portions 31 symmetrically arranged start to extend in the direction of 45 degrees downwards obliquely (or in different directions, without limitation thereto) from the point where the two third connecting portions converge with the central line, and form at least one third stretching structure 32 in the extending process until the third stretching structure reaches the terminal electrode sheet 40. The two symmetrically arranged third connecting portions 31 may have the same structure or different structures.
