Technical Field

[0001] This utility model relates to the field of electrocardiogram (ECG) analyzer technology, and more specifically, to an anti-tangling device for ECG analyzer connection cables. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] When using an electrocardiogram (ECG) analyzer to obtain the ECG signal of a human body, a signal transmission channel needs to be established between the ECG analyzer and the human body using connecting wires (also known as "lead wires").

[0004] The connection cables used in known electrocardiogram (ECG) analyzers typically include a main bus connected to the ECG analyzer and multiple branch lines extending from the main bus. In actual use, the electrode pads at the ends of each branch line are attached to the corresponding parts of the body to acquire ECG signals.

[0005] It is foreseeable that, due to the large number and length of the branches in the connecting cable, different branches will often become tangled or even knotted during use, increasing the difficulty of organizing the connecting cable later. Summary of the Invention

[0006] In view of this, the purpose of this utility model is to provide an anti-tangling device for the connecting cable of an electrocardiogram analyzer, so as to prevent different branches of the connecting cable from tangling with each other as much as possible, thereby facilitating quick tidying of the connecting cable after the electrocardiogram analyzer is used.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] This utility model discloses an anti-tangling device for an electrocardiogram analyzer connecting cable. The connecting cable includes multiple branch lines, and the anti-tangling device includes multiple limiting members corresponding to each branch line. Each limiting member includes:

[0012] The limiting member is further configured to apply a clamping force to the branch line passing through the limiting groove in order to hold the branch line within the limiting groove.

[0013] Furthermore, the limiting member also includes:

[0014] An opening / closing plate is provided at the inlet / outlet; the opening / closing plate is configured to open or close the inlet / outlet.

[0015] Furthermore, the first side of the opening and closing plate is hinged to the first side of the inlet and outlet, so that the opening and closing plate can pivot between the open position of the inlet and outlet and the closed position of the inlet and outlet.

[0016] The second side of the opening / closing plate is detachably connected to the second side of the inlet / outlet.

[0017] Furthermore, the second side of the opening and closing plate is provided with a first fixing hole, and the second side of the inlet and outlet is provided with a second fixing hole;

[0018] When the opening and closing plate is in the closed position, the first fixing hole and the second fixing hole are aligned, and removable fasteners are provided in the aligned first fixing hole and the second fixing hole.

[0019] Furthermore, the clamping force is an elastic force.

[0020] Furthermore, the limiting member also includes a limiting ring with an opening and a connecting seat, wherein the limiting ring is disposed on the connecting seat;

[0021] The inside of the limiting ring serves as the limiting groove, and the opening of the limiting ring serves as the inlet and outlet. The limiting ring is made of an elastic material.

[0022] The connection structure is provided on the connection seat.

[0023] Furthermore, the connecting seat has a first side and a second side that are opposite each other in a horizontal first direction;

[0024] The connection structure includes a snap-fit ​​groove and a snap-fit ​​part adapted to the snap-fit ​​groove, wherein the snap-fit ​​groove and the snap-fit ​​part are respectively disposed on one of the first side and the second side of the connection seat.

[0025] Furthermore, the snap-fit ​​groove is T-shaped and extends vertically through the connector.

[0026] Furthermore, the limiting rings located on both sides of the inlet and outlet are rounded.

[0027] Furthermore, the cross-sectional shape of the limiting groove matches the cross-sectional shape of the branch line;

[0028] The inner wall of the limiting groove is provided with an anti-slip structure.

[0029] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0030] The anti-entanglement device disclosed in this utility model, by setting a limiting member that can be temporarily fixed to the branch line, and setting a single limiting member to be connected with any other limiting member, can play a good role in limiting and preventing entanglement of multiple branch lines of the connecting line, and reduce the risk of different branch lines entangled with each other.

[0031] Meanwhile, since each limiting component is an independent part, the number of limiting components can be flexibly adjusted according to the number of branch lines in actual use, so that the anti-winding device is suitable for connecting lines with different numbers of branch lines, with a wide range of applications and strong flexibility in use.

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments. The same reference numerals in the accompanying drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0041] Compared to the embodiments shown in the accompanying drawings, feasible embodiments within the scope of protection of this utility model may have fewer components, have other components not shown in the drawings, different components, components arranged differently, or components with different connections, etc. Furthermore, two or more components shown in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0042] Example 1

[0043] Embodiment 1 of this utility model discloses an anti-tangling device for the connecting wire of an electrocardiogram analyzer (hereinafter referred to as "anti-tangling device"), which aims to prevent different branches 102 in the connecting wire from tangling with each other as much as possible.

[0044] To facilitate the explanation of the anti-tangling device disclosed in Embodiment 1, the structure of the connecting wires used in known electrocardiogram analyzers will be briefly described below.

[0045] like Figure 1 As shown, the connecting line may include a main line 101 and multiple branch lines 102 extending from the main line 101. Each branch line 102 has an electrode pad 103 at its end away from the main line 101. In actual use, the main line 101 is connected to an electrocardiogram analyzer, and the electrode pads 103 on each branch line 102 are attached to the corresponding parts of the human body to acquire electrocardiogram signals.

[0046] Example, Figure 1 The diagram shows a connecting wire including three branch lines 102, which can also be called a 3-lead connecting wire. Of course, the anti-tangling device disclosed in Embodiment 1 is not limited to connecting wires with three branch lines 102, but is also applicable to connecting wires with more or fewer branch lines 102, such as connecting wires with five branch lines 102.

[0047] Figure 2 The general structure of the exemplary anti-tangling device disclosed in Embodiment 1 is shown. Figure 2As shown, the anti-collision device may include multiple limiting members 10 corresponding one-to-one with the branch lines 102. Considering that the multiple branch lines 102 in the connecting line are generally arranged in a straight line after being led out from the bus 101, and that adjacent branch lines 102 are parallel to each other, when actually using the anti-entanglement device, the arrangement of the multiple limiting members 10 can be set to the same form as the arrangement of the multiple branch lines 102, that is, the multiple limiting members 10 can also be arranged in a straight line.

[0048] Figure 3 The general structure of a single limiting member 10 is shown. (As shown) Figure 3 As shown, the limiting member 10 may include a limiting groove 11 and an inlet / outlet 12. The limiting groove 11 extends along the axial direction of the branch line 102 and is adapted for the branch line 102 to pass through; that is, both ends of the limiting groove 11 in the axial direction of the branch line 102 are open. The inlet / outlet 12 communicates with the limiting groove 11, and is adapted for the branch line 102 to enter and exit the limiting groove 11. The axial direction of the branch line 102 described in this embodiment 1 can be understood as the length direction of the branch line 102.

[0049] It is understandable that, since the cross-sectional shape of a typical branch line 102 is usually circular, the cross-sectional shape of the limiting groove 11 can be set to be circular so that the cross-sectional shape of the limiting groove 11 matches the cross-sectional shape of the branch line 102, thereby increasing the contact area between the outer wall of the branch line 102 and the inner wall of the limiting groove 11 when the branch line 102 passes through the limiting groove 11.

[0050] The inlet / outlet 12 can be set at the top of the limiting groove 11 so that the branch line 102 can pass through the top of the limiting groove 11 from the inlet / outlet 12 and thus effectively prevent the branch line 102 entering the limiting groove 11 from coming out of the inlet / outlet 12.

[0051] Furthermore, the limiting member 10 is also configured to apply a clamping force to the branch line 102 passing through the limiting groove 11, thereby retaining the branch line 102 within the limiting groove 11 and preventing the branch line 102 from easily dislodging from the limiting groove 11. For example, a portion of the structure constituting the limiting groove 11 can be made of an elastic material so that when the branch line 102 passes through the limiting groove 11, the limiting member 10 can apply an elastic force as a clamping force to the branch line 102 passing through the limiting groove 11.

[0052] Continue to refer to Figure 3 The limiting member 10 also includes a connecting structure 13. Any two limiting members 10 can be detachably connected by their respective connecting structures 13. That is, any two limiting members 10 can be connected together or separated by their respective connecting structures 13.

[0053] Based on the above settings, when actually applying the anti-winding device disclosed in Embodiment 1, such as Figure 5 As shown, each branch line 102 first enters the limiting groove 11 from the inlet / outlet 12 of the corresponding limiting member 10 to temporarily fix each limiting member 10 to the branch line 102. Subsequently, multiple limiting members 10 can be arranged in a line, and adjacent limiting members 10 can be connected together by their respective connecting structures 13. Based on this, since each branch line 102 is limited by the corresponding limiting member 10, and adjacent limiting members 10 are connected to each other, the risk of different branch lines 102 tangling can be effectively reduced.

[0054] Understandably, we should continue to refer to... Figure 5 When the branch line 102 is long, simply arranging the anti-tangling device disclosed in Embodiment 1 at appropriate positions along the axial direction of the branch line 102 can effectively prevent the long branch lines 102 from tangling together. Furthermore, the anti-tangling device disclosed in Embodiment 1 is applicable to connecting lines with varying numbers of branch lines 102, thus having a wide range of applications. It is also simple and convenient to use, requiring no specialized knowledge.

[0055] Furthermore, since the electrode plates 103 on each branch 102 of the connecting wire need to be attached to different parts of the human body, at a certain axial position of the branch 102, one or more branch 102 may gradually move away from the other branch 102. In this case, for the branch 102 that are still adjacent to each other, using a corresponding number of limiting members 10 can still achieve a good limiting and anti-tangling effect. For example, in Figure 5 Of the three branch lines 102 shown, when one branch line 102 gradually moves away from the other two branch lines 102, the remaining two branch lines 102 can be limited by two limiting members 10. It can be seen that the anti-entanglement device disclosed in Embodiment 1 is highly flexible in use.

[0056] In some embodiments, the limiting member 10 may be further constructed in the manner described below, but is not limited to, so that the limiting member 10 has the functions described above.

[0057] Continue to refer to Figure 3 The limiting member 10 may further include a limiting ring 14 with an opening and a connecting seat 15. The limiting ring 14 may be disposed on the connecting seat 15, for example, at the top of the connecting seat 15. The limiting ring 14 and the connecting seat 15 may be an integral structure, for example, the limiting ring 14 and the connecting seat 15 may be manufactured by using a mold.

[0058] The inside of the limiting ring 14 serves as the aforementioned limiting groove 11, and the opening of the limiting ring 14 serves as the aforementioned inlet and outlet 12.

[0059] At this time, the entire limiting ring 14 can be made of elastic material so that when the branch line 102 enters the limiting groove 11 through the inlet and outlet 12, the limiting ring 14 can apply a sufficiently large clamping force to the branch line 102 to further improve the stability of the branch line 102 when it is located in the limiting groove 11.

[0060] The aforementioned connection structure 13 can be provided on the connection seat 15 so that any two limiting members 10 can be detachably connected by means of the connection structure 13 on their respective connection seats 15, thereby optimizing the structural design of the limiting members 10 as much as possible.

[0061] In some embodiments, such as Figure 3 As shown, the limiting rings 14 located on both sides of the inlet and outlet 12 are rounded. This design can effectively prevent the branch line 102 from being scratched by the limiting rings 14 when it enters the limiting groove 11 through the inlet and outlet 12.

[0062] In some embodiments, the inner wall of the limiting groove 11 may also be provided with an anti-slip structure (not shown in the figure) to increase the friction between the branch line 102 located in the limiting groove 11 and the limiting groove 11, and to prevent the limiting member 10 from easily sliding along the axial direction of the branch line 102. The anti-slip structure may be anti-slip texture, anti-slip protrusion, etc.

[0063] In some embodiments, refer to Figure 4 As shown, the connecting seat 15 also has a first side and a second side opposite to each other in a first horizontal direction. The first horizontal direction is perpendicular to the axial direction of the branch line 102.

[0064] The connecting structure 13 may include a snap-fit ​​groove 131 and a snap-fit ​​portion 132 adapted to the snap-fit ​​groove 131. The snap-fit ​​groove 131 and the snap-fit ​​portion 132 are respectively disposed on one of the first side and the second side of the connecting base 15. For example, the snap-fit ​​groove 131 can be disposed on the first side of the connecting base 15, and the snap-fit ​​portion 132 can be disposed on the second side of the connecting base 15. The snap-fit ​​portion 132 is adapted to snap into the snap-fit ​​groove 131.

[0065] Thus, when any two limiting members 10 need to be connected together, it is only necessary to align the snap-fit ​​part 132 on one limiting member 10 with the snap-fit ​​groove 131 on the other limiting member 10, and make the snap-fit ​​part 132 snap into the snap-fit ​​groove 131. The operation is simple and convenient.

[0066] Furthermore, the snap-fit ​​groove 131 can be a T-shaped groove to further improve the reliability of the snap-fit ​​part 132 after it is engaged with the snap-fit ​​groove 131. The snap-fit ​​groove 131 can also be a through groove extending vertically through the connecting seat 15, allowing the connecting seats 15 of two adjacent limiting members 10 to be snapped together using an upper and lower insertion method, facilitating operation.

[0067] Furthermore, a locking structure (not shown in the figure) can be provided between the snap-fit ​​part 132 and the snap-fit ​​groove 131 to effectively prevent the snap-fit ​​part 132, which is snapped into the snap-fit ​​groove 131, from coming out of the snap-fit ​​groove 131, thereby further improving the reliability of the snap-fit ​​part 132 after it is snapped into the snap-fit ​​groove 131.

[0068] The locking structure may include an elastic protrusion and a groove adapted to the elastic protrusion. The elastic protrusion and the groove are respectively provided on one of the inner wall of the locking groove 131 and the outer wall of the locking portion 132. For example, a groove may be provided on the inner wall of the locking groove 132, and an elastic protrusion adapted to the groove may be provided on the outer wall of the locking portion 132.

[0069] Thus, when the snap-fit ​​part 132 snaps into the snap-fit ​​groove 131, the elastic protrusion can snap into the corresponding groove to lock the position of the snap-fit ​​part 132, so that the snap-fit ​​part 132 cannot easily come out of the snap-fit ​​groove 131 without a sufficiently large external force.

[0070] In some embodiments, the limiting member 10 may further include a mounting portion, which may be magnetic or adhesive, so that the limiting member 10 can be temporarily fixed to a predetermined position (e.g., the outer wall of an ECG analyzer, a bed rail, etc.) through the mounting portion, thereby preventing the branch line 102 from shaking after being limited. The mounting portion may be a magnetic component such as a magnet, or an adhesive component such as double-sided tape. Furthermore, the mounting portion may be located at the bottom of the connecting seat 15 to optimize the structural design of the limiting member 10 as much as possible.

[0071] Example 2

[0072] Based on Embodiment 1, considering that after the branch line 102 enters the limiting groove 11, although applying clamping force to the branch line 102 and adding an anti-slip structure to the limiting groove 11 can effectively prevent the branch line 102 from coming out of the limiting groove 11, if the branch line 102 is accidentally pulled by a person, the branch line 102 still has a high probability of coming out of the limiting groove 11.

[0073] Therefore, in this embodiment 2, the structure of the limiting member 10 is further improved to reliably prevent the branch line 102 that enters the limiting groove 11 from coming out of the limiting groove 11.

[0074] like Figure 6 and Figure 7 As shown, the limiting member 10 disclosed in this embodiment 2 may further include an opening / closing plate 16. The opening / closing plate 16 is disposed at the inlet / outlet 12 and is configured to open or close the inlet / outlet 12.

[0075] It is understandable that by further providing an opening / closing plate 16 at the inlet / outlet 12 for opening or closing the inlet / outlet 12, after the branch line 102 enters the limiting groove 11 through the inlet / outlet 12, it only needs to pass through the opening / closing plate 16 to... Figure 7 By closing the inlet and outlet 12 as shown, the branch line 102 can be effectively prevented from coming out of the inlet and outlet 12, thereby reliably confining the branch line 102 within the limiting groove 11.

[0076] In some embodiments, to simplify the process of opening or closing the inlet / outlet 12, the first side of the opening / closing plate 16 can be hinged to the first side of the inlet / outlet 12, allowing the opening / closing plate 16 to pivot between an open position and a closed position of the inlet / outlet 12. The second side of the opening / closing plate 16 is detachably connected to the second side of the inlet / outlet 12 after crossing it, to lock the opening / closing plate 16 in the closed position or to release the lock on the opening / closing plate 16 in the closed position.

[0077] The first side of the opening / closing plate 16 and the first side of the inlet / outlet 12 can be hinged together by a hinge shaft 17. Specifically, the opening / closing plate 16 and the limiting ring 14 can be hinged together by a hinge shaft 17.

[0078] In some embodiments, such as Figure 6 As shown, the second side of the opening / closing plate 16 is provided with a first fixing hole 18, and the second side of the inlet / outlet 12 is provided with a second fixing hole 19. Specifically, the second fixing hole 19 can be formed on the limiting ring 14. When the opening / closing plate 16 is in the position shown... Figure 7 When in the closed position as shown, the first fixing hole 18 and the second fixing hole 19 are aligned, and a removable fastener 110 is provided in the first fixing hole 18 and the second fixing hole 19 after alignment. The fastener 110 may be, but is not limited to, a locking pin.

[0079] Thus, when the opening / closing plate 16 is in the closed position and the first fixing hole 18 and the second fixing hole 19 are aligned, simply inserting the fastener 110 into the first fixing hole 18 and the second fixing hole 19 will lock the opening / closing plate 16 in the closed position. Conversely, simply removing the fastener 110 from the first fixing hole 18 and the second fixing hole 19 will release the lock on the opening / closing plate 16, allowing it to pivot to the open position to open the inlet / outlet 12.

[0080] In some embodiments, the opening / closing plate 16 may also be an arc-shaped component, and the inner side of the opening / closing plate 16 is also provided with an anti-slip structure so that when the branch line 102 enters the limiting groove 11 and the opening / closing plate 16 is in the closed position, the inner side of the opening / closing plate 16 can abut against the outer wall of the branch line 102, thereby further reducing the possibility of the limiting member 10 moving axially along the branch line 102. Here, the inner side of the opening / closing plate 16 refers to the side of the opening / closing plate 16 facing the limiting groove 11 when it is in the closed position.

[0081] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
