[0028] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0029] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0030] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0031] In the description of this embodiment, the terms "upper", "lower", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0032] like Figure 1-Figure 3As shown, this embodiment provides a magnetic ECG electrode, including a patch 1 and a conductive sheet 2. The first side of the patch 1 is used to fit with the patient, and the second side of the patch 1 is provided with a first annular protrusion 11, which surrounds and forms a first accommodating cavity 10, and a first magnetic attraction portion 12 is provided at the bottom of the first accommodating cavity 10. A first conductive portion 13 that can be extended and retracted along the axial direction of the first annular protrusion 11 is convexly provided on the top surface of the first annular protrusion 11, and a plurality of first conductive portions 13 are provided, and the plurality of first conductive portions 13 are arranged at intervals along the circumference of the first annular protrusion 11. A cylindrical protrusion 21 and a second annular protrusion 22 surrounding the cylindrical protrusion 21 are provided on the first side of the conductive sheet 2, and a second accommodating cavity 20 is formed between the second annular protrusion 22 and the cylindrical protrusion 21. A second magnetic attraction portion 23 is provided on the top surface of the cylindrical protrusion 21, and a second conductive portion 24 is provided at the bottom of the second accommodating cavity 20, and the second conductive portion 24 covers the cavity bottom of the second accommodating cavity 20. The first annular protrusion 11 can be inserted into the second accommodating cavity 20, and the first magnetic attraction portion 12 and the second magnetic attraction portion 23 are magnetically attracted to each other, so that the second conductive portion 24 compresses the first conductive portion 13. It can be understood by those skilled in the art that when the first annular protrusion 11 is inserted into the second accommodating cavity 20, the cylindrical protrusion 21 is also inserted into the first accommodating cavity 10. The internal structure of the patch 1 and the conductive sheet 2 is the prior art in the art and will not be described here.
[0033] The magnetic ECG electrode provided in this embodiment has a first magnetic portion 12 at the bottom of the first accommodating cavity 10, and a second magnetic portion 23 on the top surface of the cylindrical protrusion 21. When the magnetic ECG electrode is in use, the suction force between the first magnetic portion 12 and the second magnetic portion 23 keeps the patch 1 and the conductive sheet 2 engaged. At this time, the first annular protrusion 11 on the patch 1 is inserted into the second accommodating cavity 20, which can limit the relative movement between the conductive sheet 2 and the patch 1 to a certain extent, so that the conductive sheet 2 and the patch 1 are not easily separated when the patient twists his body, thereby improving the stability of the magnetic ECG electrode when in use. In addition, when the conductive sheet 2 is buckled on the patch 1, the second conductive part 24 compresses the first conductive part 13, that is to say, when the magnetic ECG electrode is in use, the first conductive part 13 is in a compressed state, so that when the patient twists his body and causes one side of the conductive sheet 2 to slightly tilt, the first conductive part 13 can also maintain electrical connection with the second conductive part 24 by stretching, avoiding poor contact between the patch 1 and the conductive sheet 2 and affecting the ECG waveform, further improving the stability of the magnetic ECG electrode when in use.
[0034] Furthermore, if Figure 2 and Figure 3 As shown, the cylindrical protrusion 21 is cylindrical, the first annular protrusion 11 and the second annular protrusion 22 are both circular, and the cylindrical protrusion 21 and the second annular protrusion 22 are coaxially arranged, so that the conductive sheet 2 can be snapped with the patch 1 without deliberately adjusting the angle of the conductive sheet 2 around the axis of the patch 1.
[0035] Furthermore, if Figure 2 As shown, a first groove 101 is provided at the bottom of the first accommodating cavity 10, and the first magnetic attraction portion 12 is provided at the bottom of the first groove 101. When the conductive sheet 2 is buckled on the patch 1, the second magnetic attraction portion 23 extends into the first groove 101. The second magnetic attraction portion 23 cooperates with the first groove 101 to further increase the limiting effect on the conductive sheet 2 and ensure the stability of the magnetic force between the first magnetic attraction portion 12 and the second magnetic attraction portion 23.
[0036] Furthermore, if Figure 2 and Figure 3 As shown, the second magnetic portion 23 and the first groove 101 are both cylindrical, the second magnetic portion 23 is coaxially arranged with the cylindrical protrusion 21, and the first groove 101 is coaxially arranged with the first annular protrusion 11, so that the second magnetic portion 23 can be inserted into the first groove 101 without deliberately adjusting the angle of the second magnetic portion 23 around the axis of the patch 1.
[0037] Alternatively, if Figure 2 As shown, the first annular protrusion 11 is arranged in the middle of the patch 1, that is, the size of the main part of the patch 1 is larger than the size of the first annular protrusion 11, so that the patch 1 can be more firmly attached to the patient. The specific method of attaching the patch 1 to the patient is the prior art and will not be repeated here.
[0038] Alternatively, if Figure 2 As shown, a plurality of second grooves 111 are arranged on the top surface of the first annular protrusion 11, the bottom of the first conductive part 13 is arranged in the second groove 111, and the top protrudes from the top surface of the first annular protrusion 11. When the conductive sheet 2 is buckled on the patch 1, the second conductive part 24 presses the part of the first conductive part 13 protruding from the top surface of the first annular protrusion 11 back into the second groove 111. At this time, the first conductive part 13 maintains contact with the second conductive part 24 under the action of the elastic deformation recovery force. The arrangement of the second groove 111 enables the first conductive part 13 to have a sufficiently large deformation margin. The larger the elastic deformation of the first conductive part 13, the greater the elastic force of the first conductive part 13 after deformation, and the more stable the contact between the first conductive part 13 and the second conductive part 24.
[0039] Furthermore, if Figure 2 As shown, the second conductive part 24 is a compression spring contact (also called a compression spring flat contact or a compression spring terminal). The compression spring contact is a contact that can produce elastic deformation. Its specific structure and working principle are common knowledge in the field and will not be repeated here.
[0040] Optionally, the first magnetic attraction portion 12 is a neodymium magnet, and the second magnetic attraction portion 23 is an iron part, and the neodymium magnet and the iron part cooperate to form magnetic attraction.
[0041] Alternatively, if Figure 1 and Figure 3 As shown, the second side of the conductive sheet 2 is a plane. When the magnetic ECG electrode is in use, the second side of the conductive sheet 2 faces the outside of the patient's body. Setting the second side of the conductive sheet 2 as a plane can prevent the conductive sheet 2 from hooking and pulling the patient's clothes and surgical sterile towels.
[0042] Alternatively, if Figure 3 As shown, the second annular protrusion 22 extends along the periphery of the conductive sheet 2, thereby reducing the volume of the patch 1 and further preventing the periphery of the conductive sheet 2 from hooking and pulling on the patient's clothes and surgical sterile towels.
[0043] Alternatively, if Figure 1 and Figure 3 As shown, the outer periphery of the conductive sheet 2 is provided with a plurality of third grooves 25, and the plurality of third grooves 25 are arranged at intervals along the circumference of the conductive sheet 2. After the magnetic ECG electrode is used, the medical staff can use the fingertips to insert into the third grooves 25 to pull the conductive sheet 2 to remove the conductive sheet 2 from the patch 1, thereby facilitating the medical staff to disassemble the magnetic ECG electrode and avoiding damage to the magnetic ECG electrode by pulling the wire on the conductive sheet 2 to separate the conductive sheet 2 from the patch 1. Specifically, in the present embodiment, three third grooves 25 are provided.
[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
