Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electrocardiogram accessories technology, specifically relating to a multi-interface dynamic electrocardiograph ten-lead cable. Background Art
[0002] Lead wires are specialized cables used in conjunction with electrocardiographs (ECGs). A ten-core ECG lead wire transmits signals to the ECG machine, enabling data transmission for medical monitoring, diagnosis, and testing.
[0003] The prior art includes a ten-core electrocardiograph lead wire with patent publication number CN212541934U. This patent includes an outer sheath, with a wound outer shielding layer on the inner wall of the outer sheath; a wrapping layer inside the wound outer shielding layer; a ground wire between the wound outer shielding layer and the wrapping layer; ten inner core wires and one filler wire inside the wrapping layer; an extruded layer on the outer surface of the filler wire; a wound inner shielding layer on the outer surface of each inner core wire; and an inner middle sheath on the outer surface of each wound inner shielding layer. The conductor of this invention is made of silver-plated copper alloy components, which has advantages such as high conductivity, corrosion resistance, and strong heat resistance; the insulation layer is made of FEP material, which has high impact resistance; the wound outer shielding layer is made of tin-plated copper components, and the wound inner shielding layer is made of tin-plated tin-copper alloy components, with each inner core wire individually shielded, resulting in good shielding effect and excellent mechanical properties. This product transmits patient physiological signals without external interference and with accurate signal transmission. However, it still has the following shortcomings in actual use: In practice, the product lacks corresponding protection during use. When it is bent during use, due to the lack of a structure to increase its bending radius and provide protection, the internal core wire is easily damaged due to the small bending radius, thus reducing the inconvenience of using the product.
[0004] Therefore, a multi-interface dynamic electrocardiograph with ten leads is needed to solve the problem of damage caused by the lack of bending protection technology in the existing technology. Utility Model Content
[0005] The purpose of this invention is to provide a multi-interface dynamic electrocardiograph with ten leads to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-interface dynamic electrocardiograph with ten leads, comprising a lead body and an outer sheath. The outer sheath is disposed on the outside of the lead body, and an outer shielding layer is disposed on the inner side of the outer sheath. A first protective mechanism is disposed on the inner side of the outer shielding layer. Ten inner core wires are disposed on the inner side of the first protective mechanism and are evenly distributed in a circular pattern inside the lead body. A second protective mechanism is disposed on the inner side of the ten inner core wires, and a filler wire is disposed on the inner side of the second protective mechanism.
[0007] The outer surface of the inner core wire is provided with an inner middle sheath layer, the outer surface of the filler wire is provided with an extrusion layer, the inner middle sheath layer is located between the first protective mechanism and the second protective mechanism, and the extrusion layer is located inside the second protective mechanism.
[0008] It should be noted in the scheme that the first protective mechanism includes a first insulating layer and a first spring tube. The first insulating layer is located outside the ten inner core wires and is attached to the inner middle layer. The first spring tube is located between the outer shielding layer and the first insulating layer and is located outside the ten inner core wires.
[0009] It is worth noting that the first spring tube has elastic restoring properties and is made of a metallic material.
[0010] Furthermore, it should be noted that the second protective mechanism includes a second insulating layer and a second spring tube. The second insulating layer is disposed inside the ten inner core wires and is bonded to the inner liner layer. The second spring tube is disposed inside the second insulating layer and is disposed outside the extruded layer and bonded to it.
[0011] In a preferred embodiment, the second spring tube has elastic restoring properties and is made of a metallic material.
[0012] Compared with the prior art, the multi-interface dynamic electrocardiograph ten-lead cable provided by this utility model has at least the following beneficial effects:
[0013] (1) By setting the first and second protective mechanisms on the outside and inside of the ten inner core wires respectively, it can be ensured that when the main body of the conductor is used, the bending radius of the inner core wire can be increased sufficiently during the bending process, so as to avoid damage caused by the bending radius of the inner core wire being too small during the bending process, thereby ensuring the transmission efficiency after connection. At the same time, its structure is simple and easy to implement. Attached Figure Description

[0018] The present invention will be further described below with reference to the embodiments.
[0019] Please see Figure 1-3 This utility model provides a multi-interface dynamic electrocardiograph ten-lead cable, including a lead cable body 1 and an outer sheath 2. The outer sheath 2 is located on the outside of the lead cable body 1. An outer shielding layer 3 is provided on the inner side of the outer sheath 2. A first protective mechanism 4 is provided on the inner side of the outer shielding layer 3. Ten inner core wires 5 are provided on the inner side of the first protective mechanism 4 and are evenly distributed in a circle inside the lead cable body 1. A second protective mechanism 6 is provided on the inner side of the ten inner core wires 5. A filler wire 7 is provided on the inner side of the second protective mechanism 6.
[0020] The outer surface of the inner core wire 5 is provided with an inner middle layer 501, and the outer surface of the filler wire 7 is provided with an extrusion layer 701. The inner middle layer 501 is located between the first protective mechanism 4 and the second protective mechanism 6, and the extrusion layer 701 is located inside the second protective mechanism 6.
[0021] The outer sheath 2, outer shielding layer 3, inner core wire 5 and filler wire 7 have been specifically described in the patent publication number CN212541934U, and will not be elaborated further here.
[0022] By setting a first protective mechanism 4 and a second protective mechanism 6 on the outside and inside of the ten inner core wires 5 respectively, it can be ensured that when the main body of the conductor wire 1 is used, the bending radius of the inner core wires 5 can be increased sufficiently during the bending process, avoiding damage caused by the bending radius of the inner core wires 5 being too small during the bending process, thereby ensuring the transmission efficiency after connection. At the same time, its structure is simple and easy to implement.
[0023] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the first protective mechanism 4 includes a first insulating layer 401 and a first spring tube 402. The first insulating layer 401 is disposed on the outside of the ten inner core wires 5 and is attached to the inner middle sheath 501. The first spring tube 402 is disposed between the outer shielding layer 3 and the first insulating layer 401 and is disposed outside the ten inner core wires 5. The first spring tube 402 has elastic restoring properties and is made of metal material.
[0024] The first insulating layer 401 is disposed on the outside of the inner core wire 5 and is attached to the inner sheath 501. Its main function is to provide electrical insulation, prevent current from flowing from one inner core wire to another, and ensure the accuracy and safety of signal transmission. The insulating layer also provides physical protection for the inner core wire 5, preventing direct damage to the inner core wire 5 from the external environment, such as corrosion and wear, thereby extending the service life of the lead wire body 1. At the same time, the elastic characteristics of the first spring tube 402 can also play a role in buffering and shock absorption. When the lead wire body 1 is subjected to bending, stretching or vibration, the first spring tube 402 can absorb some energy, reduce the impact on the inner core wire 5 and the first insulating layer 401, and protect the stability of signal transmission. In summary, the first protective mechanism 4, through the synergistic effect of the first insulating layer 401 and the first spring tube 402, provides multiple functions such as electrical insulation, physical protection, structural reinforcement, buffering and shock absorption, and shape retention for the lead wire body 1, ensuring the stable transmission and service life of the lead wire body 1 in complex environments.
[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the second protective mechanism 6 includes a second insulating layer 601 and a second spring tube 602. The second insulating layer 601 is disposed inside the ten inner core wires 5 and is attached to the inner sheath layer 501. The second spring tube 602 is disposed inside the second insulating layer 601 and is disposed outside the extruded layer 701 and is attached to it. The second spring tube 602 has elastic restoring properties and is made of metal material.
[0026] Similarly, the second spring tube 602 can further improve the stability of the conductor body 1 in use.
[0027] This solution has the following working process: When this device is used and connected for transmission, if the main body 1 of the lead wire bends during use, the first spring tube 402 and the second spring tube 602 ensure that the ten inner core wires 5 inside maintain a large bending radius during bending, thus preventing damage to the inner core wires 5 due to a small bending radius, which would affect the data transmission. Furthermore, the first spring tube 402 and the second spring tube 602 ensure that the main body 1 of the lead wire can return to its original shape after bending, avoiding inconvenience caused by prolonged bending, thereby improving its ease of use and service life. The first insulating layer 401 and the second insulating layer 601 are located outside the inner sheath 501, ensuring that the inner core wires 5 maintain high insulation within the main body 1 of the lead wire, thereby improving its stability during use.
[0028] In summary, by setting the first protective mechanism 4 and the second protective mechanism 6 on the outside and inside of the ten inner core wires 5 respectively, it can be ensured that when the main body of the conductor wire 1 is used, the bending radius of the inner core wires 5 can be increased sufficiently during the bending process, avoiding damage caused by the inner core wires 5 having too small a bending radius during the bending process, thereby ensuring the transmission efficiency after connection. At the same time, its structure is simple and easy to implement.
[0029] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
