Description

Technical Field

[0001] The present invention relates to the technical field of medical cables, and in particular to an anti-interference medical transmission cable. Background Art

[0002] ICE cardiac ultrasound cable requires 64 signal channels, which means that 64 wires are needed for transmission. There are currently two methods in the market. One is that all 64 wires are coaxial structure, and the signal transmission is stable, but the overall cable outer diameter is too large, which cannot be applied to catheters with smaller inner diameters. The other is a Y-type 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, which affects the doctor's diagnosis and judgment. The existing shielding layer is usually formed by weaving multiple strands of metal wires or wrapping a metal film around the insulating medium layer to shield electromagnetic interference or useless external signal interference. For the shielding layer woven from metal wires, the content of the metal wires and the tightness of the weaving will affect its anti-interference ability. In order to obtain a better shielding effect, it is necessary to form a new shielding layer on the basis of the original metal shielding. While further enhancing the shielding effect, this shielding layer also needs to be easy to manufacture and reduce production costs to meet the use requirements. Therefore, an anti-interference medical transmission cable is needed. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide an anti-interference medical transmission cable to solve the problem of preventing mutual interference during cable transmission in the prior art.

[0004] To achieve the above objectives and other related objectives, the present invention provides the following technical solutions:

[0005] An anti-interference medical transmission cable, comprising:

[0006] A conductor tube, wherein a transmission conductor is arranged in the conductor tube, an outer sheath is wrapped around the conductor tube, an electron tube and a ground tube are arranged between the outer wall of the conductor tube and the inner wall of the outer sheath, and the electron tube and the ground tube are alternately arranged along the circumference of the conductor tube;

[0007] A shielding layer, wherein the shielding layer comprises a coaxial shielding layer and an outer shielding layer, wherein the coaxial shielding layer is arranged on the outer wall of the conductor tube and between the electron tube and the ground tube, and the coaxial shielding layer wraps the outer wall of the conductor tube;

[0008] The outer shielding layer is arranged between the inner wall of the outer jacket layer and the electron tube and the ground tube, and the outer shielding layer is closely attached to the inner wall of the outer jacket layer.

[0009] To implement the above technical solution, by arranging the electron tube and the ground tube alternately along the circumference of the conductor tube, the use stability of the electron tube and the ground tube can be ensured, and the mutual influence generated during the transmission process between them can be reduced. By setting the coaxial line shielding layer and the outer shielding layer, the conductor tube and the outer sheath are shielded respectively, so that the conductor tube and the outer sheath can be separated during the transmission process, thereby improving the stability and reliability of data transmission, and avoiding the mutual influence generated between the conductor tube and the outer sheath during the transmission process. The coaxial line shielding layer is wrapped around the outer wall of the conductor tube, and the conductor tube can be used to play an auxiliary supporting role for the coaxial line shielding layer, thereby ensuring the use stability and use reliability of the coaxial line shielding layer. By setting the outer shielding layer close to the inner wall of the outer sheath, the use stability of the outer shielding layer can be ensured, and the outer shielding layer can have molding characteristics, and the outer shielding layer will not be wrinkled after twisting.

[0010] In one embodiment of the present invention, the coaxial cable shielding layer and the outer shielding layer both include carbon nanotube ropes, which are woven alternately. The carbon nanotube ropes of the coaxial cable shielding layer are wound around the conductor tube at an angle with the central axis of the conductor tube, and the angle is less than 45°. The carbon nanotube ropes of the outer shielding layer are bonded to the inner wall of the outer coating layer.

[0011] To implement the above technical solution, the carbon nanotubes have excellent resilience and anti-distortion capabilities. The carbon nanotube rope in the coaxial cable shielding layer is wound around the conductor tube at an angle with the central axis of the conductor tube. When the cable is twisted, the coaxial cable shielding layer has sufficient torsional characteristics to meet the torsion requirements. Setting the angle less than 45° can improve the stability of the carbon nanotube rope on the conductor tube, and when subjected to torsional deformation, the carbon nanotube rope can be reset with better synchronization, thereby ensuring the reliability of the carbon nanotube rope. Bonding the carbon nanotube rope in the outer shielding layer to the inner wall of the outer sheath layer can avoid the carbon nanotube rope from falling off from the outer sheath after twisting, resulting in the carbon nanotube rope being unable to cover the inner wall of the outer sheath during subsequent use.

[0012] In one embodiment of the present invention, the carbon nanotube rope is wound on the conductor tube in two layers, and the two layers of carbon nanotube rope are wound on the conductor tube in opposite directions.

[0013] To implement the above technical solution, in order to ensure the stability of the carbon nanotube rope on the conductor tube, two layers of carbon nanotube rope are wound on the conductor tube in opposite directions to ensure the reliability of reset after twisting during use and comprehensive coverage of the conductor tube.

[0014] In one embodiment of the present invention, the coaxial cable shielding layer also includes a conductive layer, which is arranged between the conductor tube and the carbon nanotube rope. The conductive layer is a copper tape, which is spirally wound around the conductor tube along the axial direction of the conductor tube. The thickness of the conductive layer is greater than the thickness of the carbon nanotube rope.

[0015] To implement the above technical solution, the copper tape is spirally wound around the conductor tube along the axial direction of the conductor tube, which can isolate the signal interference between the conductor tube and the electron tube and the ground tube, thereby improving the stability of the signal transmission process. The copper tape is spirally wound around the conductor tube, which can improve the use stability of the copper tape. The copper tape can be used to wrap the conductor tube more evenly, so that the carbon nanotube rope on the conductor tube can be tightly attached to the conductor tube, thereby ensuring the use stability and reliability of the carbon nanotube rope, further strengthening the signal interference between the conductor tube and the electron tube and the ground tube during signal transmission, and making the thickness of the conductive layer greater than the thickness of the carbon nanotube rope can improve the overall torsional strength of the cable and reduce the possibility of torsional deformation.

[0016] In one embodiment of the present invention, a graphene copper foil layer is disposed between the inner wall of the outer coating layer and the outer shielding layer, and the thickness of the graphene copper foil layer is greater than the thickness of the carbon nanotube rope.

[0017] To implement the above technical solution, by setting a graphene copper foil layer, the anti-corrosion performance between the inner wall of the outer layer and the outer shielding layer can be improved, and its use stability is better, and the heat dissipation stability during data transmission can also be improved.

[0018] In one embodiment of the present invention, the outer layer includes an outermost flexible layer and a silicone layer located inside the flexible layer. A deformation cavity is arranged in the silicone layer. The deformation cavities are arranged in a plurality of groups at equal intervals along the circumference of the conductor tube. The deformation cavities are arc-shaped cavities. The opening direction of the arc-shaped cavities is arranged at an angle to the center line of the conductor tube. The arc-shaped openings of the plurality of groups of deformation cavities all have the same angle with the center line of the conductor tube.

[0019] To implement the above technical solution, by arranging a silicone layer on the inner side of the flexible layer, the material characteristics of the silicone layer can be utilized to improve the overall torsional property of the cable and the recovery property after torsion, and the silicone layer can also maintain the support of the cable, and by arranging a deformation cavity in the silicone layer, a deformation space can be provided for the deformation of the silicone layer after the cable is twisted, and the deformation cavity can provide a deformation space for the deformation of the silicone layer after being squeezed, thereby ensuring the stability of the cable when torsion occurs, reducing the destructiveness of torsion to the silicone layer, thereby increasing the service life of the silicone layer, and further ensuring that the cable can still maintain its original support characteristics after long-term use, thereby improving the stability of the cable in use.

[0020] In one embodiment of the present invention, a deformation protrusion is provided in the silicone layer, the deformation cavity is located in the deformation protrusion, the deformation protrusion is a conical protrusion, the deformation protrusion is embedded in the flexible layer, a snap-fit ​​groove is provided in the flexible layer, and the deformation protrusion matches the shape of the snap-fit ​​groove.

[0021] To implement the above technical solution, by setting a deformation protrusion, space can be provided for the arrangement of the deformation cavity, and by setting the deformation protrusion as a conical protrusion, the stability of deformation during torsion can be improved, and by setting a snap-fit ​​groove in the flexible layer, the deformation protrusion matches the shape of the snap-fit ​​groove, which can improve the connection stability between the silicone layer and the flexible layer, and when subjected to torsion deformation, the deformation synchronization between the silicone layer and the flexible layer can be improved.

[0022] In one embodiment of the present invention, the radial dimension of the ground tube is smaller than the radial dimension of the electron tube, an electron wire is arranged in the electron tube, and a Kevlar filling wire is arranged between the inner wall of the electron tube and the outer wall of the electron wire.

[0023] To implement the above technical solution, by arranging a Kevlar filling line between the inner wall of the electron tube and the outer wall of the electron wire, the tensile strength of the electron tube can be improved and the use stability of the electron tube can be ensured.

[0024] As described above, an anti-interference medical transmission cable of the present invention has the following beneficial effects: by arranging the electron tube and the ground tube alternately along the circumference of the conductor tube, the use stability of the electron tube and the ground tube can be ensured, and the mutual influence generated during the transmission process between them can be reduced; by setting the coaxial line shielding layer and the outer shielding layer, the conductor tube and the outer sheath are shielded respectively, so that the conductor tube and the outer sheath can be separated during the transmission process, thereby improving the stability and reliability of data transmission, and avoiding the influence between the conductor tube and the outer sheath during the transmission process; the coaxial line shielding layer is wrapped around the outer wall of the conductor tube, and the conductor tube can be used to provide auxiliary support for the coaxial line shielding layer, thereby ensuring the use stability and use reliability of the coaxial line shielding layer; by setting the outer shielding layer close to the inner wall of the outer sheath, the use stability of the outer shielding layer can be ensured, so that the outer shielding layer can have molding characteristics, and the outer shielding layer will not be wrinkled after twisting.

[0034] By arranging the electron tube 4 and the ground tube 5 alternately along the circumference of the conductor tube 1, the use stability of the electron tube 4 and the ground tube 5 can be ensured, and the mutual influence generated during the transmission process between them can be reduced. By setting the coaxial shielding layer 6 and the outer shielding layer 7, the conductor tube 1 and the outer sheath 3 are shielded respectively, so that the conductor tube 1 and the outer sheath 3 can be separated during the transmission process, thereby improving the stability and reliability of data transmission, and avoiding the mutual influence generated between the conductor tube 1 and the outer sheath 3 during the transmission process.

When the cable is twisted, the coaxial cable shielding layer 6 has sufficient torsional characteristics to meet the torsion requirements. Setting the angle less than 45° can improve the stability of the carbon nanotube rope 8 on the conductor tube 1. When subjected to torsional deformation, the carbon nanotube rope 8 can be reset with better synchronization, thereby ensuring the reliability of the carbon nanotube rope 8. Bonding the carbon nanotube rope 8 of the outer shielding layer 7 to the inner wall of the outer coating 3 can prevent the carbon nanotube rope 8 from falling off from the outer coating 3 after twisting, resulting in the carbon nanotube rope 8 being unable to cover the inner wall of the outer coating 3 during subsequent use.
