Description

Technical Field

[0001] The utility model relates to the technical field of medical cable structures, in particular to an anti-intertwining type medical cable. Background Art

[0002] Medical cables, such as those used for image transmission in CT machines, MRI machines, etc., have high requirements for signal quality and cable flexibility. In such cables, power lines and signal lines are often set at the same time, but the high-frequency electromagnetic waves generated in the power line often affect the signal transmission of the signal line, thereby interfering with the signal quality received by the receiving end. Moreover, since there are many wire harnesses in such cables, once the wire harnesses are entangled, the signal transmission quality of the wire harness will be affected. After the wire harnesses are entangled, the entire wire harness will be unevenly stressed during the use of the cable, and the wire harness protective cover is easily damaged in the densely entangled area, which further affects the signal transmission. Therefore, an anti-intertwining medical cable is needed. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide an anti-entanglement type medical cable, which is used to solve the problem in the prior art that multiple wire harnesses in the cable will be entangled with each other and affect the stability of signal transmission.

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

[0005] An anti-entanglement medical cable, comprising:

[0006] A protective cover, wherein the protective cover wraps the entire set of cables;

[0007] A braided shield is provided between the inside of the protective cover and the cable to tighten the cable;

[0008] A cable, comprising a conductor wire, a digital signal wire, an optical fiber wire, a conductive wire and a power wire, wherein the conductor wire, the digital signal wire, the optical fiber wire, the conductive wire and the power wire are sequentially arranged in the circumferential direction of the inner wall of the braided shield, and a filling layer is filled in the central space of the braided shield to support the cable to be close to the inner wall of the braided shield.

[0009] To implement the above technical solution, the conductor wires, digital signal wires, optical fiber wires, conductive wires and power wires are arranged in sequence along the circumferential direction of the inner wall of the braided shield, and then the central space of the braided shield after the wiring harnesses are arranged is filled with a filling layer. The filling layer can be used to support the arranged wiring harnesses, so that each wiring harness can be close to the inner wall of the braided shield, thereby avoiding misalignment and entanglement of the internal wiring harnesses after the cable is twisted during use.

[0010] In an embodiment of the present invention, the filling material in the filling layer is Kevlar cotton.

[0011] To implement the above technical solution, the characteristics of Kevlar cotton material are utilized to maintain the supporting effect on the wire harness while also having sufficient flexibility to meet the torsion and deformation of the cable during use.

[0012] In one embodiment of the present invention, the braided shield is an overlapping soft copper tape, and the braided shield is wrapped with a protective layer both inside and outside.

[0013] By implementing the above technical solution, the braided shielding of overlapping soft copper tapes can maintain the use strength of the braided shielding while meeting the deformation requirements during use.

[0014] In an embodiment of the present invention, the protective layer is made of TAPE material.

[0015] By implementing the above technical solution, the protective layer can provide protection for the braided shielding, and can also prevent the braided shielding from causing damage to the cable it is attached to when twisting during the use of the cable, thereby improving the overall stability of the cable.

[0016] In one embodiment of the present invention, the power cord is a 30AWG power cord, and the outer layer of the power cord is wrapped with a double-layer signal shield, and the signal shield is an FEP layer and a SB layer alternately arranged on the outer layer of the power cord.

[0017] By implementing the above technical solution and utilizing double-layer signal shielding, the interference of the power cord to surrounding cables during use can be reduced, the transmission stability of surrounding cables can be improved, and the FEP layer and SB layer alternately arranged on the outer layer of the power cord can improve the stability and intensity of use of the power cord.

[0018] In one embodiment of the present invention, the conductor wire, digital signal wire, optical fiber wire and conductive wire are all 32AWG wires, and the outer layers of the conductor wire, digital signal wire and optical fiber wire are all wrapped with a single layer of signal shielding.

[0019] By implementing the above technical solution, the single-layer signal shielding can better wrap the conductor wires, digital signal wires and optical fiber wires, and can also improve the convenience of twisting the cable during the use of the cable, making the cable more flexible to use.

[0020] In an embodiment of the present invention, the protective cover is made of thermoplastic polyurethane.

[0021] The above technical solution is implemented to meet the deformation requirements during actual use and can also protect internal cables.

[0022] In one embodiment of the present invention, the conductor wire, digital signal wire, optical fiber wire, conductive wire and power wire are hollow between the outer sides and the inner wall of the braided shield.

[0023] The implementation of the above technical solution can, on the one hand, provide deformation space for the wiring harness deformation, and on the other hand, provide better conduction buffering, thereby improving the overall stability of the cable.

[0024] As described above, the utility model provides an anti-entanglement type medical cable, which has the following beneficial effects: the conductor wires, digital signal wires, optical fiber wires, conductive wires and power wires are sequentially arranged in the braided shield along the circumferential direction of the inner wall of the braided shield, and then the filling layer is used to fill the central space of the braided shield after the wire bundles are arranged, so that the filling layer can be used to support the arranged wire bundles, so that each wire bundle can be close to the inner wall of the braided shield, avoiding the misalignment and entanglement of the internal wire bundles after the cable is twisted during use, and utilizing the material characteristics of Kevlar cotton to maintain the supporting effect on the wire bundle while having sufficient flexibility to meet the torsion and deformation of the cable during use.
