Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to an electrocardiogram electrode clip. Background Technology

[0002] Electrocardiogram (ECG) monitoring is a crucial tool for the clinical diagnosis of heart disease. Its core function is to transmit electrocardiographic signals from the human body to a monitoring device via electrodes, enabling real-time monitoring of cardiac activity. ECG electrode clips, as key components connecting the body to the electrode leads, typically use a clamping structure to secure the electrode pads to the patient's body surface.

[0003] Existing ECG electrode clips are typically designed to a fixed size. While they can achieve the clamping function, they are difficult to adapt to arms or other body parts of varying sizes. This results in situations where the clamping force is insufficient for thinner arms, leading to slippage, while for thicker arms, the clamping force may be too tight, causing discomfort. Consequently, the applicability of these devices is limited. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electrocardiogram electrode clip.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An electrocardiogram electrode clip includes a first clamping arm, a second clamping arm, and an electrode pad disposed on the side of the first clamping arm near the second clamping arm;

[0007] The first clamping arm and the second clamping arm are each provided with a beveled block on the opposite side. The relative distance between the two beveled blocks on the side closer to the clamping arm is smaller than the relative distance on the side farther from the clamping arm.

[0008] The inclined surfaces of the two inclined blocks facing each other are provided with equally spaced locking posts;

[0009] The two aforementioned inclined blocks are constrained by a locking block. The locking block has a locking groove, and the locking post can rotate and fit into the locking block through the locking groove. The locking block also constrains the position of the locking post by a clamp.

[0010] The side of the aforementioned card block away from the clamping arm is fitted with an elastic piece via a second slot.

[0011] Each of the aforementioned inclined blocks has a first slot on the side of each locking post away from the clamping arm, and the other end of the aforementioned elastic piece is engaged in the first slot.

[0012] Preferably, a first inclined surface, a second inclined surface, and a third inclined surface are provided at intervals on the inclined surfaces of the two inclined blocks facing each other;

[0013] The first inclined surface is located on the side of the locking post near the clamping arm, the third inclined surface is located on the side of the locking post away from the clamping arm, and the first slot is opened on the second inclined surface.

[0014] Preferably, the first inclined surface is configured to initially fit the inclined block against the slot of the card block on the side close to the clamping arm, and the third inclined surface is configured to fit the inclined block against the slot of the card block away from the clamping arm after rotation, and the angle between the first inclined surface and the third inclined surface is 20°-30°.

[0015] Preferably, the side of the aforementioned locking block away from the clamp is fitted with a baffle that constrains the position of the locking post.

[0016] Preferably, the second slot passes through the side of the card block away from the clamp, and the first slot passes through the side of the beveled block near the clamp. The passage method is configured to facilitate the insertion of the card block with the elastic piece into the first slot of the two beveled blocks.

[0017] Preferably, the two elastic sheets described above are arranged symmetrically about the card block.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. When performing ECG examinations on individuals with wrists or ankles of varying thicknesses, adjust the position of the clamping blocks according to the thickness of the individual's wrists and ankles, ensuring the blocks are positioned to fit the appropriate size for the individual. The distance between the first and second clamping arms of this ECG electrode clamp can be adjusted according to actual usage needs, facilitating clamping of wrists or ankles of different thicknesses.

[0020] 2. When the first clamping arm and the second clamping arm are rotated, the rotation angle of the first clamping arm and the second clamping arm is limited by the cooperation between the third inclined surface on the inclined block and the slot on the card block away from the clamping arm, preventing the first clamping arm and the second clamping arm from rotating excessively, thus improving the stability of the ECG electrode clip during use.

[0033] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0034] Example

[0035] like Figures 1-6 As shown, an electrocardiogram (ECG) electrode clip includes a first clamping arm 11, a second clamping arm 12, and an electrode plate 13 disposed on the side of the first clamping arm 11 near the second clamping arm 12. The first clamping arm 11, the second clamping arm 12, and the electrode plate 13 are conventional settings for existing ECG electrode clips, used to clamp the wrist and ankle of the person performing the examination.

[0036] In one embodiment, such as Figures 1-3As shown, both the first clamping arm 11 and the second clamping arm 12 have inclined blocks 21 on opposite sides. The relative distance between the two inclined blocks 21 on the side closer to the clamping arm is smaller than the relative distance on the side farther from the clamping arm. The inclined surfaces of the two inclined blocks 21 are equally spaced with locking posts 22. Multiple sets of locking posts 22 are provided on the inclined blocks 21, so that the locking block 31 can be connected to different locking posts 22 to adjust the distance between the first clamping arm 11 and the second clamping arm 12 of the ECG electrode clamp, adapting to people with different arm sizes, thereby meeting the needs of people of different ages who need to perform ECG examinations.

[0037] When the locking block 31 is moved toward the clamping arm, the distance between the first clamping arm 11 and the second clamping arm 12 can be increased to meet the needs of people with thicker arms for electrocardiogram examinations; when the locking block 31 is moved away from the clamping arm, the distance between the first clamping arm 11 and the second clamping arm 12 can be decreased to meet the needs of people with thinner arms for electrocardiogram examinations.

[0038] In one embodiment, such as Figures 1-3 , Figure 5 As shown, the locking posts 22 of the two inclined blocks 21 are constrained by locking blocks 31. Locking blocks 31 have locking slots 32, allowing the locking posts 22 to rotate and fit against the locking blocks 31. The locking blocks 31 also constrain the position of the locking posts 22 via clamps 33. On the inclined surfaces of the two inclined blocks 21 facing each other, a first inclined surface 211, a second inclined surface 212, and a third inclined surface 213 are spaced apart. The first inclined surface 211 is located on the side of the locking post 22 closer to the clamping arm, and the third inclined surface 213 is located on the side of the locking post 22 away from the clamping arm. A first slot 23 is formed on the second inclined surface 212. The first inclined surface 211 is configured to allow... The inclined block 21 initially fits against the slot 32 of the clamping block 31 on the side near the clamping arm. The third inclined surface 213 is configured so that after the inclined block 21 rotates, it fits against the slot 32 of the clamping block 31 on the side away from the clamping arm. The angle between the first inclined surface 211 and the third inclined surface 213 is 20°-30°. This angle range is used to limit the rotation angle of the inclined block 21 relative to the clamping block 31, thereby constraining the rotation angle of the first clamping arm 11 and the second clamping arm 12 around the clamping block 31, preventing the first clamping arm 11 and the second clamping arm 12 from rotating excessively, and improving the stability of the first clamping arm 11 and the second clamping arm 12 when rotating.

[0039] Each locking post 22 is equipped with a first inclined surface 211, a second inclined surface 212, and a third inclined surface 213. The locking post 22 cooperates with the locking block 31 through the inclination angle of the first inclined surface 211 and the third inclined surface 213, so that the inclined block 21 can rotate around the locking block 31 with the first clamping arm 11 and the second clamping arm 12. When rotating, the locking post 22 rotates in the locking groove 32 of the locking block 31. The relative position of the locking post 22 and the locking block 31 is constrained by the clamp 33 and the baffle 36, so that the locking block 31 will not separate from the locking post 22, thereby improving the stability of the first clamping arm 11 and the second clamping arm 12 when rotating.

[0040] In one embodiment, such as Figure 6 As shown, after the first clamping arm 11 and the second clamping arm 12 rotate, when the inclined block 21 rotates to its maximum extent, the third inclined surface 213 is attached to the side of the slot 32 on the card block 31 away from the clamping arm, thereby constraining the maximum rotation distance of the first clamping arm 11 and the second clamping arm 12, and further improving the stability of the first clamping arm 11 and the second clamping arm 12 when rotating.

[0041] In one embodiment, such as Figures 3-5 As shown, the side of the clamping block 31 away from the clamping arm is connected to an elastic piece 35 through a second slot 34. The inclined block 21 has a first slot 23 on the side of each clamping post 22 away from the clamping arm. The other end of the elastic piece 35 is engaged in the first slot 23. When the force applied to the first clamping arm 11 and the second clamping arm 12 is released, the first clamping arm 11 and the second clamping arm 12 are reset under the action of the elastic piece 35, so that the first inclined surface 211 of the inclined block 21 fits against the side of the clamping groove 32 on the inclined block 21 near the clamping arm.

[0042] The second slot 34 penetrates the side of the locking block 31 away from the clamp 33, and the first slot 23 penetrates the side of the beveled block 21 near the clamp 33. The penetration method is configured to facilitate the insertion of the locking block 31, carrying the elastic pieces 35, into the first slots 23 of the two beveled blocks 21. This allows the two elastic pieces 35 to be first secured in the second slot 34 of the locking block 31, and then, through the locking block 31, secured in the first slots 23 of the two beveled blocks 21. Subsequently, the elastic pieces 35 can act on the two beveled blocks 21, and consequently, on the first clamping arm 11 and the second clamping arm 12. The two elastic pieces 35 are symmetrically arranged about the locking block 31 to ensure that the force exerted by the elastic pieces 35 on the first clamping arm 11 and the second clamping arm 12 is equal.

[0043] The elastic sheet 35 causes the two inclined blocks 21 to be initially positioned such that the first inclined surface 211 is attached to the side of the slot 32 on the card block 31 near the clamping arm.

[0044] In one embodiment, such as Figure 5As shown, a baffle 36 that constrains the position of the locking post 22 is engaged on the side of the locking block 31 away from the clamp 33. Through the cooperation of the baffle 36 and the clamp 33, the constraint effect of the locking block 31 on the locking post 22 is improved.

[0045] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
