Description

Technical Field

[0001] The utility model relates to the technical field of medical cables, in particular to an anti-mutual interference type cardiac ultrasound coaxial cable. Background Art

[0002] ICE cardiac ultrasound cable requires 64 signal channels, which means 64 wires are needed for transmission. There are currently two methods on the market. One is that all 64 wires are coaxial cable structures, which has stable signal transmission, but the overall cable outer diameter is too large and cannot be used for catheters with smaller inner diameters. The other is a Y-shaped transmission structure, with an electronic wire in the middle and electronic wires and ground wires around. Since the 64-channel signals are transmitted simultaneously, the middle electronic wire is interfered by the signal transmission of the adjacent electronic wires when transmitting the signal, resulting in partial distortion of the image, affecting the doctor's diagnosis. Therefore, a mutual interference-proof cardiac ultrasound coaxial cable is needed. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide an anti-mutual interference cardiac ultrasound coaxial cable, which is used to solve the problem of mutual interference between isolation signals in the prior art.

[0004] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0005] A mutual interference-proof cardiac ultrasound coaxial cable, comprising:

[0006] A coaxial line, wherein the coaxial line is wrapped with a shielding layer;

[0007] Electronic wires, the electronic wires are equally divided and arranged around the coaxial line in the circumferential direction of the coaxial line;

[0008] Ground wires, which are equally divided and arranged around the coaxial line along the central signal line, and are arranged between adjacent signal lines;

[0009] The outer shield is wrapped around the electronic wire and the ground wire.

[0010] To implement the above technical solution, by wrapping a shielding layer on the coaxial line, the signal interference of the electronic wires and the ground wires that are aligned with the coaxial line and arranged equally circumferentially during use can be isolated, thereby ensuring the stability of use between the coaxial line and the electronic wires and the ground wires. The outer shielding can wrap the electronic wires and the ground wires, thereby avoiding the thicker outer protective layer used in traditional cables. The outer shielding is thinner in thickness and can meet the needs of use in narrower spaces.

[0011] In one embodiment of the present invention, the shielding layer on the coaxial line is copper winding, copper foil or aluminum foil tape to isolate the coaxial line from signal interference between adjacent electronic wires.

[0012] To implement the above technical solution, copper winding, copper foil or aluminum foil wrapping is used on the coaxial cable to isolate the signal interference between the coaxial cable and the adjacent electronic wires, and to reduce the radial dimension of the wrapped coaxial cable, thereby ensuring that the outer diameter of the entire cable is minimized, which is conducive to inserting the blue catheter with a smaller outer diameter.

[0013] In one embodiment of the present invention, the axes of the coaxial line, the electronic line and the ground line are arranged in parallel.

[0014] The implementation of the above technical solution can facilitate the wrapping of the coaxial line, electronic wire and ground wire by the outer shield, ensure the uniformity of the radial dimension of the outer shield, and utilize the outer shield wrapping to improve the stability of the coaxial line, electronic wire and ground wire during use.

[0015] In an embodiment of the present invention, the outer shielding layer is a copper foil tape.

[0016] To implement the above technical solution, the use of copper foil tape can ensure the wrapping of the outer shielding, minimize the thickness of the outer screen, and minimize the outer diameter of the entire cable, which is conducive to the insertion of the blue catheter with a smaller outer diameter. The blue catheter needs to enter the heart from the human blood vessels to realize the ultrasonic imaging function. It can also ensure the strength of the outer shielding and is not easy to be damaged after deformation.

[0017] In an embodiment of the present invention, the electronic wire is wrapped with an insulating layer, and the insulating layer is made of Teflon material.

[0018] To implement the above technical solution, the insulating layer of Teflon material is used to improve the use stability of the electronic wire and reduce the signal interference generated during the use of the electronic wire.

[0019] As described above, the utility model provides an anti-mutual interference cardiac ultrasound coaxial cable, which has the following beneficial effects: by wrapping a shielding layer on the coaxial line, the signal interference of the electronic wires and the ground wires aligned with the coaxial line and arranged circumferentially equally can be isolated during use, thereby ensuring the stability of use between the coaxial line and the electronic wires and the ground wires; the outer shielding can wrap the electronic wires and the ground wires, thereby avoiding the thicker outer protective layer used in traditional cables; the outer shielding is thinner in thickness and can meet the use requirements in a narrower space; by wrapping copper, copper foil or aluminum foil tape on the coaxial line, the signal interference between the coaxial line and adjacent electronic wires can be isolated, and the radial size of the coaxial line after winding can be reduced, thereby ensuring that the outer diameter of the entire cable is minimized, which can facilitate the insertion of a blue catheter with a smaller outer diameter.

[0024] The following specific embodiments illustrate the implementation of the present invention, and those familiar with the technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Specific embodiment 1:

[0026] See also Figure 1 The utility model provides an anti-mutual interference cardiac ultrasound coaxial cable, including a coaxial line 1 wrapped with a shielding layer 2, electronic wires 3 are equally arranged around the coaxial line 1 along the circumference of the coaxial line 1, and ground wires 4 are equally arranged around the coaxial line 1 along the circumference of the central signal line. In addition, the ground wire 4 is arranged between adjacent signal wires, and an outer shielding layer 5 is wrapped around the electronic wire 3 and the ground wire 4.

[0027] By wrapping the shielding layer 2 on the coaxial line 1, the signal interference of the electronic wire 3 and the ground wire 4 which are equally spaced circumferentially aligned with the coaxial line 1 during use can be isolated, thereby ensuring the use stability between the coaxial line 1 and the electronic wire 3 and the ground wire 4. The outer shield 5 can wrap the electronic wire 3 and the ground wire 4, thereby avoiding the thicker outer protective layer used in traditional cables. The outer shield 5 is thinner and can meet the use in a narrower space.

[0028] The shielding layer 2 on the coaxial cable 1 is copper winding, copper foil or aluminum foil tape to isolate the signal interference between the coaxial cable 1 and the adjacent electronic wire 3. By winding copper winding, copper foil or aluminum foil tape on the coaxial cable 1, the signal interference between the coaxial cable 1 and the adjacent electronic wire 3 can be isolated, and the radial dimension of the coaxial cable 1 after winding can be reduced, thereby ensuring that the outer diameter of the entire cable is minimized, which can facilitate the insertion of a blue catheter with a smaller outer diameter.

[0029] The axes of the coaxial line 1, the electronic wire 3 and the ground wire 4 are arranged in parallel, which can facilitate the wrapping of the coaxial line 1, the electronic wire 3 and the ground wire 4 by the outer shield 5, ensure the uniformity of the radial dimensions of the outer shield 5, and use the outer shield 5 to wrap and improve the stability of the coaxial line 1, the electronic wire 3 and the ground wire 4 during use.

[0030] The outer shield 5 is a copper foil tape. The copper foil tape can ensure the wrapping of the outer shield 5 and minimize the thickness of the outer screen, so that the outer diameter of the entire cable can be minimized, which is conducive to the insertion of the blue catheter with a smaller outer diameter. The blue catheter needs to enter the heart from the human blood vessels to realize the ultrasonic imaging function. It can also ensure the use strength of the outer shield 5 and is not easy to be damaged after deformation. Moreover, during the wrapping process of the outer shield 5, the outer shield 5 will be deformed so that the inner wall of the outer shield 5 can stick to the electronic wire 3 and the ground wire 4, thereby minimizing the outer diameter of the finished product and facilitating the insertion of the blue catheter.

[0031] The electronic wire 3 is wrapped with an insulating layer made of Teflon material. The insulating layer made of Teflon material is used to improve the use stability of the electronic wire 3 and reduce signal interference generated during the use of the electronic wire 3. Specific embodiment 2:

[0033] like Figure 2 As shown, the difference between the specific embodiment 2 and the specific embodiment 1 is that the number of the electronic wires 3 and the ground wires 4 is different. The number of the electronic wires 3 of the present application can be adjusted according to the needs, but the layout of the electronic wires 3 and the ground wires 4 remains unchanged.

[0034] The utility model can isolate the signal interference of the electronic wires and the ground wires which are aligned with the coaxial line and arranged equally in the circumferential direction during use by wrapping a shielding layer on the coaxial line, thereby ensuring the use stability between the coaxial line and the electronic wires and the ground wire. The outer shielding can wrap the electronic wires and the ground wire, thereby avoiding the thicker outer protective layer used in traditional cables. The outer shielding thickness is smaller and can meet the use requirements in a narrower space. By wrapping copper, copper foil or aluminum foil tape on the coaxial line, the signal interference between the coaxial line and the adjacent electronic wires can be isolated, and the radial size of the coaxial line after winding can be reduced, thereby ensuring that the outer diameter of the entire cable is minimized, which can facilitate the insertion of a blue catheter with a smaller outer diameter.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. All equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
