Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.

The numbering of the components as such, e.g., "second", "first", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).

The embodiment provides an electrocardiogram lead wire which is used for being connected with a signal acquisition part and transmitting an electric signal acquired by the signal acquisition part to host equipment.

Referring to fig. 1-3, the electrocardiograph lead wire includes an electrode clip 100, a limiting member 200, a sheath 300 and a connecting wire 400. The electrode clamp 100 is used for directly contacting with the electrode connector and transmitting the electric signal collected by the electrode connector to the connecting wire 400, and then transmitting the electric signal to the host part for processing through the connecting wire 400.

The electrode clamp 100 includes a left electrode 110, a right electrode 120 and a connecting member 130, at least one of the left electrode 110 and the right electrode 120 is connected to the connecting member 130, and the connecting member 130 is used to connect with a connecting wire 400 for transmitting electrical signals. The left electrode 110 and the right electrode 120 are stacked and together define a receiving hole 101 (shown in fig. 1) for an electrode tab to pass through. When the electrode tab is fixed, the hole wall of the housing hole 101 clamps the electrode tab by the change in the hole diameter, thereby fixing the electrode tab.

At least one of the left electrode 110 and the right electrode 120 is made of an elastic material and/or is driven by an elastic member, so that the left electrode 110 and the right electrode 120 can relatively move under the action of an external force to enlarge the accommodating hole 101, so as to facilitate the placement of an electrode joint. When the external force disappears, the left electrode 110 and the right electrode 120 can move relatively under the elastic force to shrink the accommodation hole 101 for clamping the electrode joint.

Since the size of the receiving hole 101 may vary, the electrode holder 100 can be adapted to various sizes of electrode tabs on the market, such as one of the electrode tabs 500 shown in fig. 4. The left electrode 110 and the right electrode 120 can be relatively moved by an external force to increase the size of the receiving hole 101, so that the electrode tabs 500 of different sizes can be inserted into the receiving hole 101. When the external force disappears, the elastic restoring force of the electrode clamp 100 resets the left electrode 110 and the right electrode 120 to reduce the accommodating hole 101, and the electrode connector 500 is clamped to be firmly connected, so that stable and reliable signal transmission is ensured.

The sheath 300 is wrapped around the electrode clip 100 and the connecting wire 400, wherein at least a portion of the left electrode 110 and at least a portion of the right electrode 120 are exposed from the sheath 300. The sheath body 300 can wrap the electrode clip 100 and the connecting wire 400 therein through injection molding, so that the electrode clip 100, the connecting wire 400 and the sheath body 300 are integrated, the manufacturing and the processing are convenient, and the electrode clip 100 and the connecting wire 400 are firmly and reliably connected. The sheath 300 is usually made of an insulating material, which can ensure that the electrode clip 100 is disconnected from the outside, and can also make the connecting wire 400 have certain toughness when swinging, thereby avoiding damage to the sheath of the connecting wire 400.

Further, referring to fig. 1-3, the position-limiting member 200 forms a position-limiting structure in the stacking direction of the left electrode 110 and the right electrode 120, so that the position-limiting structure is formed in the stacking direction of the left electrode 110 and the right electrode 120, and the left electrode 110 and the right electrode 120 are prevented from separating during the relative movement, so that the left electrode 110 and the right electrode 120 are attached together, thereby ensuring that the left electrode 110 and the right electrode 120 can smoothly form the desired accommodating hole 101.

In one embodiment, the position limiting member 200 includes an upper position limiting member 201 and a lower position limiting member 202. The upper and/or

lower retainers

201, 202 may be fixedly disposed in the stacking direction of the left and

right electrodes

110, 120, for example, the upper and/or

lower retainers

201, 202 may be disposed in the stacking direction separately from the left and

right electrodes

110, 120, and of course, the upper and/or

lower retainers

201, 202 may also be fixedly connected to or integrally formed with one of them.

Referring to fig. 1-3, in one embodiment, the upper limiting member 201 and the lower limiting member 202 are fixedly connected to or integrally formed with the right electrode 120. The upper and lower limiting

members

201 and 202 are both arranged to protrude from the right electrode 120 to the left electrode 110, and the left electrode 110 is located in the area between the upper and lower limiting

members

201 and 202 and the right electrode 120.

Of course, in one embodiment, the upper limiting member 201 can be folded from the upper edge of the right electrode 120 to the side of the left electrode 110. The lower stopper 202 may be folded from the lower edge of the right electrode 120 to the left electrode 110.

Referring to fig. 2, in an embodiment, the upper limiting member 201 and the lower limiting member 202 are folded to form a U-shaped space with the right electrode 120, for example, a portion of the upper limiting member 201 and a portion of the lower limiting member 202 are parallel to the right electrode 120, so as to form an upper U-shaped space and a lower U-shaped space, and the left electrode 110 is accommodated in the U-shaped space. In addition, the upper limiting member 201 and the lower limiting member 202 arranged in a folded manner can effectively avoid the electrode joint 500 from being misplaced.

Similarly, in an embodiment, the upper limiting member 201 and the lower limiting member 202 may be fixedly connected to or integrally formed with the left electrode 110. The upper limiting piece 201 and the lower limiting piece 202 are arranged in a protruding mode from the left electrode 110 to the right electrode 120, and the right electrode 120 is located in the area between the upper limiting piece 201 and the lower limiting piece 202.

Further, in one embodiment, the upper limiting member 201 is folded from the upper edge of the left electrode 110 to the side of the right electrode 120. The lower stopper 202 is formed by folding from the lower edge of the left electrode 110 to the side of the right electrode 120.

Further, in an embodiment, the upper limiting member 201 and the lower limiting member 202 are folded to form a U-shaped space with the left electrode 110, for example, a portion of the upper limiting member 201 and a portion of the lower limiting member 202 are disposed parallel to the left electrode 110, so as to form an upper U-shaped space and a lower U-shaped space. The right electrode 120 is accommodated in the U-shaped space.

Of course, the upper stopper 201 and the lower stopper 202 may be provided at other positions than the left electrode 110 or the right electrode 120, as long as the upper stopper and the lower stopper can limit the left electrode 110 and the right electrode 120 in the stacking direction.

Further, continuing with fig. 1-3, in one embodiment, the left electrode 110 and the right electrode 120 are sheet-shaped. The left electrode 110 has a first through hole 111, and the right electrode 120 has a second through hole 121 (as shown in fig. 2, the second through hole 121 is not labeled in fig. 1 because the second through hole 121 partially overlaps the accommodating hole 101 defined in the present embodiment to indicate the position of the accommodating hole 101). The first through hole 111 and the second through hole 121 are stacked and offset so that the first through hole 111 and the second through hole 121 at least partially overlap, and the overlapping portion forms the accommodation hole 101. When the left electrode 110 and the right electrode 120 move relatively, the overlapping portion of the first through hole 111 and the second through hole 121 will become larger or smaller, i.e. the accommodating hole 101 can change its size with the relative movement of the left electrode 110 and the right electrode 120, so as to adapt to the electrode contacts 500 with different sizes.

Further, referring to fig. 2 and 3, in an embodiment, the edge of the second through hole 121 protrudes toward the first through hole 111 to form an aperture limiting portion 122. The aperture-limiting portion 122 passes through the first through hole 111 to limit the closest position where the left electrode 110 and the right electrode 120 approach each other and the farthest position where they depart from each other.

With continued reference to fig. 2 and 3, in one embodiment, the wall of the first through hole 111 includes a large hole portion 112 and a small hole portion 113 smaller than the large hole portion 112. The large hole portion 112 may be considered as a partial hole wall of a larger through hole, and the small hole portion 113 may be considered as a partial hole wall of a smaller through hole. The large hole portion 112 is abutted against the small hole portion 113, and encloses or encloses with other members the first through hole 111 described above. A transition landing is formed at the junction of the large aperture portion 112 and the small aperture portion 113. The aperture stop 122 extends into the large bore portion 112. The aperture-limiting portion 122 and the small hole portion 113 define a housing hole 101. The aperture stopper 122 has a shape and a size that can move in the space surrounded by the large hole portion 112 and can be caught by the transition catch. That is, the aperture stopper 122 is movable in the space surrounded by the large hole portion 112 by an external force, so that the accommodation hole 101 surrounded by the aperture stopper 122 and the small hole portion 113 is enlarged. When the external force disappears, the aperture limiting portion 122 abuts against the transition clamping table and cooperates with the small hole portion 113 to define the minimum aperture of the accommodating hole 101.

Further, referring to fig. 1-3, in an embodiment, the accommodating hole 101 defined by the left electrode 110 and the right electrode 120 is a closed hole structure. The closed accommodation hole 101 is formed by the left electrode 110 and the right electrode 120. Compared with an open groove body structure, the closed hole body structure can ensure that the electrode joint 500 is difficult to fall from the containing hole 101 after being installed, and the convenience of operators is improved.

Referring to fig. 3, in an embodiment, the connecting member 130, the left electrode 110 and the right electrode 120 are separate structures and are finally connected into a whole by a fixing manner. In other embodiments, the connecting member 130, the left electrode 110 and the right electrode 120 may be integrally formed by using a conductive metal material.

Further, referring to fig. 3, in an embodiment, the connecting member 130 includes a connecting body 132 and two connecting legs 131 connected to the connecting body 132, and the left electrode 110 and the right electrode 120 are respectively connected to one connecting leg 131. The sheath 300 is sleeved on the connecting body 132 and the connecting leg 131, and forms two sheath legs.

The connecting member 130 has a substantially Y-shaped configuration. The connecting body 132 is a lower supporting portion of a Y-shaped structure, and the two connecting legs 131 are two branches of the Y-shaped structure respectively. When the left electrode 110 and the right electrode 120 are relatively moved, the two connection legs 131 are deformed accordingly. The connection leg 131 provides an elastic restoring force to help the left and

right electrodes

110 and 120 to be reset when the external force is removed (the left and

right electrodes

110 and 120 may have an elastic restoring force themselves).

The connection member 130 has a connection groove in which the connection wire 400 is fixedly installed. Specifically, the connection groove may be provided on the connection body 132. The electrode clip 100 may be connected to the connection wire 400 by riveting, thereby improving the firmness and reliability of the connection.

The electrode clip 100 will typically have a large number of voids, both to save cost and to adapt to part shape and movement. It is easy for an operator to mis-insert the electrode tabs 500 into these voids, resulting in misassembly of the electrode tabs 500. In one embodiment, the electrode holder 100 has an anti-misloading stop extending into the gap beyond the receiving hole 101 to prevent the electrode tab 500 from being misloaded.

Further, referring to fig. 1 and 2, in one embodiment, the sheath 300 may be provided with a label 301, and the label 301 is used to guide the medical staff to connect the electrode connector 500 according to the label. The label 301 can be directly engraved on the mold (displayed when the sleeve body 300 is injection molded) by being adhered or being an insert so as to guide medical personnel to connect the corresponding electrode connectors 500 according to the marks of the characters, thereby improving the accuracy and efficiency of the operation.

The present invention has been described in terms of specific examples, which are provided to aid understanding of the invention and are not intended to be limiting. For a person skilled in the art to which the invention pertains, several simple deductions, modifications or substitutions may be made according to the idea of the invention.
