[0020] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0021] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] According to an embodiment of the present invention, a lead wire anti-entanglement device is provided, which can also be called a lead wire tidying device or a lead wire protection device. Since electrocardiographs or electrocardiograph monitors are both precision monitoring instruments, when using electrocardiographs or electrocardiograph monitors, the entanglement and knotting of multiple lead wires not only affects the work efficiency of medical staff and the accuracy of instrument use, but also causes the lead wires to wear each other when tying or untying knots, significantly reducing the service life of the lead wires. Therefore, it is necessary to provide a lead wire anti-entanglement device to avoid the problem that medical staff can only tangle and store multiple wires together after using the electrocardiograph or electrocardiograph monitor, resulting in cross-knotting between multiple lead wires.

[0023] refer to Figure 1 The lead wire anti-winding device includes a lead wire 1 and a spring coil 2, wherein one end of the lead wire 1 is a fixed end, which is fixedly connected to an electrocardiograph or an electrocardiograph monitor, and the other end of the lead wire 1 is a free end, which is fixedly connected to an electrode.

[0024] Combined with reference Figure 1 and Figure 2The spring coil 2 is a spirally bent coil that can be elastically deformed along its axis. A fixing point 21 is provided at each end of the spring coil 2. A buckle or cable tie can be provided at the fixing point 21. After the lead wire 1 passes through the spring coil 2 along its axis, the fixed end and free end of the lead wire 1 are fixedly connected to the spring coil 2 at the fixing point 21, respectively, to secure the lead wire 1 within the spring coil 2 and prevent multiple lead wires from becoming entangled and knotted. The length of the spring coil 2 when in use is greater than that of the lead wire 1, i.e., the maximum length of the spring coil 2 after elastic deformation due to stretching is greater than the length of the lead wire 1, thereby preventing the spring coil 2 from undergoing plastic deformation when the lead wire 1 is in use. It should be noted that the length of the spring coil here refers to the length of the straight line segment on the axis of the spring coil, not the unfolded length of the spring coil.

[0025] The lead wire anti-winding device specifically includes a use state and a storage state. When the lead wire anti-winding device is not subjected to external force, it is in the storage state, such as Figure 1 As shown, the spring coil 2 contracts along the axial direction so that the lead wire 1 is bent in the spring coil 2, thereby storing the lead wire 1 in the spring coil 2; when the lead wire anti-winding device is subjected to external force, that is, when the lead wire anti-winding device is stretched, it is in use, as shown in FIG. Figure 3 As shown, the spring coil 2 is stretched by an external force, causing the lead wire 1 to straighten within the spring coil 2, thereby securing the electrode at the free end of the lead wire 1 to the patient for ECG monitoring. After the patient completes ECG monitoring, the electrode is removed from the patient. The spring coil 2 is no longer subject to external tension and retracts, allowing the lead wire 1 to be bent and stored within the spring coil 2 again. Multiple hooks or storage structures can also be provided on the sidewalls of the electrocardiograph or monitor to store the lead wire anti-entanglement device while it is in storage.

[0026] When the spring coil 2 is in the storage state, the lead wire 1 is too long, which may cause its middle part to extend out of the spring coil 2, thereby causing the lead wire 1 to become entangled with other lead wires of the same (or different) electrocardiograph or electrocardiograph monitor or cables of other instruments, or a single lead wire may become entangled with itself or hooked on other instruments due to being too long. In actual use, electrocardiographs or electrocardiograph monitors are often used together with other instruments to monitor the real-time status of patients. Therefore, when stored, it is easy for cables to cross-entangle with each other or for part of the lead wire extending from the spring coil 2 to hook with other instruments or cables. In order to avoid the above situation, one or more limit points 22 may also be set in the spring coil 2. Continue to refer to Figure 2In the embodiment of the present application, there is one limiting point 22, which is located on the middle portion of the spring coil 2. In other embodiments of the present application, there may be multiple limiting points 22, which are evenly distributed on the spring coil 2. A buckle or tie may also be provided at the limiting point 22 of the spring coil 2 to securely connect the portion of the lead wire 1 between its fixed end and free end to the spring coil 2 via the limiting point 22, thereby limiting the position of the lead wire 1 within the spring coil 2 and preventing the middle portion of the lead wire 1 from extending beyond the spring coil 2 due to excessive length.

[0027] According to an embodiment of the present invention, there is also provided an ECG monitoring instrument using the above-mentioned lead wire anti-entanglement device, which can be an instrument such as an electrocardiograph or an electrocardiograph connected to multiple lead wires. Specifically, the ECG monitoring instrument includes: a host for receiving, processing and displaying electrocardiogram data and a plurality of lead wire anti-entanglement devices connected to the host, wherein the plurality of lead wire anti-entanglement devices specifically include: a plurality of lead wires and a plurality of spring coils equal in number to the plurality of lead wires. The structure of each lead wire anti-entanglement device is consistent with the above and will not be repeated here. Each lead wire passes through a spring coil along the axial direction of the spring coil and is fixed by a buckle or a cable tie provided on the spring coil, thereby fixing different lead wires in different spring coils so that each lead wire can be accommodated separately to prevent different lead wires from being entangled and knotted with each other.

[0028] In actual use, multiple lead wire anti-winding devices can first be respectively set in different storage structures on the side wall of the ECG monitoring instrument; after taking out the lead wire anti-winding device from the storage structure, each lead wire anti-winding device is stretched separately to change the lead wire anti-winding device from the storage state to the use state, so as to fix the electrodes at the free ends of the lead wires on different parts of the patient's body; after the monitoring is completed, the electrodes are removed from the patient's body, and the lead wire anti-winding device automatically retracts to the storage state, and the lead wire anti-winding device is put back into the storage structure on the ECG monitoring instrument to complete the storage.

[0029] According to the embodiments of the present application, a spring coil is provided outside the lead wire and the lead wire is fixedly connected to the spring coil, so that the lead wire can be straightened as the spring coil is stretched, and can be bent as the spring coil automatically retracts, thereby achieving the goal of storing the lead wire in the spring coil. The operation is simple and convenient, and the situation of multiple lead wires being cross-entangled due to mutual interference is avoided, which not only improves the work efficiency of medical staff when using it, but also extends the service life of the lead wire.
