Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a shadowless lead electrode clip. Background Art

[0002] In electrocardiogram (ECG) lead wires, electrode plates are placed at two points on the body surface. The wires are connected to the positive and negative terminals of the ECG machine's galvanometer, allowing the potential difference (i.e., voltage) between the two points to be measured. This connection method and the method of placing the electronic plates in an ECG machine are called leads. The patient-side electrode of the lead wire clamps the electrode posts to obtain changes in the body's electrical potential. Shadowless leads are used in X-ray environments, requiring lead wires made of no metal. Existing shadowless lead electrode clamps have a small deformation range under pressure, require high clamping pressure, are inconvenient to install, and the front support is prone to cracking or deformation after repeated use, rendering them unusable. Utility Model Content

[0003] To address the problems of inconvenient operation and susceptibility to cracking or deformation in existing shadowless lead electrode clips, this invention provides a shadowless lead electrode clip that is easy to operate and not easily damaged.

[0004] This utility model provides a shadowless conductive electrode clamp, including a conductive clamp. The conductive clamp includes a left clamping arm and a right clamping arm. The left clamping arm has a left clamping head at its front end, and the right clamping arm has a right clamping head at its front end. The left clamping head and the right clamping head are respectively provided with a left clamping groove and a right clamping groove arranged opposite to each other. A support beam for connecting the left clamping arm and the right clamping arm is provided between the left clamping arm and the right clamping arm and near one end of the left clamping head and the right clamping head. A curved elastic element is provided between the tail end of the left clamping arm and the tail end of the right clamping arm. A gap groove is provided between the support beam and the left clamping head and the right clamping head.

[0005] As a further improvement of this utility model, both the supporting beam and the spacer groove are arc-shaped structures.

[0006] As a further improvement of this utility model, the curved elastic element is provided with an elastic bending portion that bends toward one end of the supporting beam.

[0007] As a further improvement of this utility model, the inner side of the middle portion of the left clamping arm and the inner side of the middle portion of the right clamping arm are provided with two protrusions.

[0008] As a further improvement of this utility model, the shadowless lead electrode clamp also includes a lead cable, which is fixedly connected to the tail end of the right clamp arm.

[0009] As a further improvement of this utility model, a label pasting groove is provided on one side of the right clamping arm.

[0010] As a further improvement of this utility model, the distance between the tail end of the left clamping arm and the tail end of the right clamping arm and the supporting crossbeam is greater than the distance between the left clamp and the right clamp and the supporting crossbeam.

[0011] As a further improvement of this utility model, the width of the tail end of the right clamping arm is greater than the width of the tail end of the left clamping arm.

[0012] As a further improvement of this utility model, the curved elastic element has a Z-shaped structure.

[0013] As a further improvement of this utility model, the connecting cable is a carbon fiber cable.

[0014] The beneficial effects of this utility model are: it can separate the left and right clamps by applying a small force, and it can also increase the number of deformations, making it less prone to breakage, extending its service life, and providing a better clamping effect.

[0017] In the description of this utility model, it should be understood that if there are descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientation or positional relationship, the orientation description may be based on the orientation or positional relationship shown in the accompanying drawings. This is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0018] In the description of this utility model, if there is a description of quantity, "several" means one or more, "more than" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the number itself, while "above," "below," "within," etc. are understood to include the number itself. If there is a description of "first" or "second," it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] like Figure 1 As shown, this utility model discloses a shadowless conductive electrode clamp, including a conductive clamp. The conductive clamp includes a left clamping arm 1 and a right clamping arm 2. The front end of the left clamping arm 1 is provided with a left clamping head 3, and the front end of the right clamping arm 2 is provided with a right clamping head 4. The left clamping head 3 and the right clamping head 4 are respectively provided with a left clamping groove and a right clamping groove arranged opposite to each other. A support beam 5 for connecting the left clamping arm 1 and the right clamping arm 2 is provided between the left clamping arm 1 and the right clamping arm 2 and near the left clamping head 3 and the right clamping head 4. The support beam 5 is an elastic support beam. A curved elastic element 6 is provided between the tail end of the left clamping arm 1 and the tail end of the right clamping arm 2. A gap groove 7 is provided between the support beam 5 and the left clamping head 3 and the right clamping head 4.

[0021] In use, press the tail ends of the left clamping arm 1 and the right clamping arm 2 to overcome the elastic force of the curved elastic element 6. The support beam 5 forms a lever fulcrum, and the left clamp 3 and right clamp 4 will open simultaneously due to elastic deformation. Then, the left clamp 3 and right clamp 4 are clamped onto the electrode post. After releasing, the left clamp 3 and right clamp 4 will clamp the electrode post under the rebound and reset action of the support beam 5 and the action of the curved elastic element 6 at the tail end, achieving a stable conductive effect. The spacer groove 7 can provide deformation space and can also increase the length of the support beam 5 without affecting the clamping effect of the left clamp 3 and right clamp 4. Increasing the length of the support beam 5 can give it a larger deformation range, so that the left clamp 3 and right clamp 4 can be separated by applying a small force. It can also increase the number of deformations, making it less prone to breakage and extending the service life.

[0022] In this invention, both the supporting beam 5 and the spacer groove 7 are arc-shaped structures, which can more easily deform when pressed, allowing the left clamp 3 and the right clamp 4 to separate quickly.

[0023] In this utility model, the curved elastic element 6 is provided with an elastic bending part that bends toward one end of the supporting beam 5, which can effectively expand the left clamping arm 1 and the right clamping arm 2, thereby ensuring the clamping force of the left clamping head 3 and the right clamping head 4.

[0024] In this utility model, the inner side of the middle portion of the left clamping arm 1 and the inner side of the middle portion of the right clamping arm 2 are provided with two protrusions 8, which not only ensure the strength of the left clamping arm 1 and the right clamping arm 2, but also limit the compression deformation of the left clamping arm 1 and the right clamping arm 2, preventing the support beam 5 from breaking due to excessive compression deformation of the left clamping arm 1 and the right clamping arm 2.

[0025] In this utility model, the shadowless lead electrode clip also includes a lead cable 9, which is fixedly connected to the tail end of the right clamping arm 2. The lead cable 9 is a carbon fiber cable, and the lead cable 9 and the right clamping arm 2 are injection molded structures, which can ensure reliable connection and stable conductivity.

[0026] In this invention, a label pasting groove 10 is provided on one side of the right clamping arm 2, which can be used to paste electrode color marks for easy differentiation.

[0027] In this invention, the distance between the tail ends of the left clamping arm 1 and the right clamping arm 2 and the supporting beam 5 is greater than the distance between the left clamp 3 and the right clamp 4 and the supporting beam 5. This, combined with the curved elastic element 6, ensures clamping force while allowing for effortless separation of the left clamp 3 and the right clamp 4.

[0028] In this invention, the width of the tail end of the right clamping arm 2 is greater than the width of the tail end of the left clamping arm 1, so that it can be fully connected with the connecting cable 9.

[0029] In this invention, the curved elastic element 6 has a U-shaped structure.

[0030] This utility model has a simple structure, provides stable and reliable clamping, is easy to operate, and has a longer service life.

[0031] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
