Abstract
Description
Technical Field
[0001] The present application relates to the field of cable technology, and in particular to a low-latency medical equipment image transmission line. Background Art
[0002] In recent years, the medical industry has been developing rapidly driven by technological progress and medical needs, and further demands have been placed on the digitization and intelligence of medical equipment. With the integration of high-tech technologies such as artificial intelligence and 3D printing technology, medical equipment has placed higher requirements on high-speed and stable network connections. Since the image transmission data volume of medical equipment is large and needs to be transmitted in real time, the transmission line is required to have a large data transmission capacity. At the same time, it is necessary to ensure the consistency of the transmission data between multiple groups of signal lines in the transmission line. Therefore, higher requirements are also placed on the "inter-pair delay difference" performance between multiple pairs of signal lines of the transmission line. For this reason, it is necessary to design a low-latency medical equipment image transmission line that meets the above performance. Utility Model Content

[0012] Figure 1 This is a schematic diagram of the low-latency medical device image transmission line according to an embodiment of the present application. DETAILED DESCRIPTION
[0013] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0014] Example
[0015] In order to solve the above technical problems, this embodiment provides a low-latency medical equipment image transmission line, such as Figure 1As shown, there are at least 11 twisted-pair groups 10, a polyester tape layer 20, a first aluminum foil layer 30, a braided layer 40, and an outer layer 50 sequentially wrapped around the twisted-pair groups 10. The twisted-pair groups 10 include two twisted signal wires 11 and a second aluminum foil layer 12 wrapped around the signal wires 11. Filler strips 60 are used to fill the gaps between the twisted-pair groups 10. The 11 twisted-pair groups 10 ensure that the transmission line has a large data transmission capacity. The filler strips 60 ensure the roundness of the 11 twisted-pair groups 10 after cabling. The polyester tape layer 20 wraps and secures the 11 twisted-pair groups 10. At the same time, the first aluminum foil layer 30 and the braided layer 40 serve as a shielding structure to prevent leakage of the transmission signal of the twisted-pair groups 10 and improve the anti-interference capability against external signals. The second aluminum foil layer 12 provides shielding protection for the signal wires 11, preventing mutual interference between the signals of the twisted-pair groups 10, and further ensuring the stability and consistency of signal transmission.
[0016] Specifically, the signal line 11 includes a plurality of twisted conductors and an insulating layer covering the conductors, wherein the insulating layer is a foamed PE layer. For example, the conductor can be a soft tinned conductor. The use of multiple twisted tinned conductors can improve the high flexibility and bending resistance of the signal line 11, prevent damage to the conductor caused by post-processing and mechanical damage, thereby ensuring the stability of the signal transmission performance. The foamed PE layer is used as the core wire insulation. The foamed PE layer can effectively reduce the dielectric constant of the insulating medium, and can reduce the wire diameter while ensuring the impedance matching of the wire, thereby ensuring that the flexibility requirements of the medical line can be met. At the same time, the lower dielectric constant can reduce the signal transmission delay and ensure the real-time transmission of data.
[0017] Furthermore, this embodiment uses 11 twisted-pair cable groups 10 as an example. These 11 twisted-pair cable groups 10 are divided into a center layer and an outer layer. The center layer includes two twisted-pair cable groups 10 twisted relative to each other, while the outer layer includes nine twisted-pair cable groups 10 twisted and wrapped around the outer circumference of the center layer. The nine twisted-pair cable groups 10 are evenly wrapped around the two twisted-pair cable groups 10 in the center layer. Filler strips 60 are then placed between the center layer and the outer layer, resulting in a rounded appearance after the nine twisted-pair cable groups 10 are evenly wrapped around the center layer. For example, the filler strips 60 are located on both sides of the two center twisted-pair cable groups 10. The filler strips 60 also enhance the cable's tensile strength.
[0018] When all the twisted pair groups 10 are twisted into a cable with the same pitch, the actual length of the two twisted pair groups 10 in the center layer will be different from the actual length of the nine twisted pair groups 10 in the outer layer. This results in poor performance of the inter-pair delay difference between the twisted pair groups 10. In order to further reduce the inter-pair delay difference between the twisted pair groups 10, as a preferred embodiment, the twisting pitch of the two center twisted pair groups 10 is different from the twisting pitch of the nine outer twisted pair groups 10, so that the actual length of the 11 twisted pair groups 10 after cabling is the same. Exemplarily, the twisting pitch of the two twisted pair groups 10 in the center layer is greater than that of the nine twisted pair groups 10 in the outer layer, so that the actual length of each twisted pair group 10 in the finished cable is the same, thereby reducing the inter-pair delay difference of each twisted pair group 10 and ensuring the consistency of the transmission signals of multiple twisted pair groups 10. Furthermore, in some embodiments, during the cabling process of the twisted pair groups 10, the payout cage is rotated synchronously with the twisting process to achieve detwisting, thereby reducing damage to the twisted pair groups 10 during the cabling process. Furthermore, during cabling, the cage stranding machine can be used to control the cabling pitch of different twisted pair groups 10, ensuring that the actual physical length of all twisted pair groups 10 after cabling is the same, effectively reducing the inter-pair delay difference between the twisted pair groups 10.
[0019] Furthermore, the braiding density of the braided layer 40 is greater than 80%. The braided layer 40 can be woven with tinned copper wire. The larger braiding density can further improve the wire's anti-electromagnetic interference ability. The outer layer 50 is made of PVC material to meet the physical performance requirements of medical wires.
[0020] In summary, the present application solution is to set up at least 11 groups of twisted wire pairs, and sequentially cover the twisted wire pairs with a polyester tape layer, a first aluminum foil layer, a braided layer, and an outer layer. The twisted wire pairs include two twisted signal wires and a second aluminum foil layer covering the signal wires. The gaps between the twisted wire pairs are filled with filling strips. By setting up 11 groups of twisted wire pairs, it is ensured that the transmission line has a large data transmission capacity. The filling strips are used to ensure the roundness of the 11 groups of twisted wire pairs after cabling. The polyester tape layer is used to wrap and fix the 11 groups of twisted wire pairs. At the same time, the first aluminum foil layer and the braided layer are used as a shielding structure to avoid leakage of the transmission signal of the twisted wire pair group and improve the anti-interference ability against external signals. By setting up the second aluminum foil layer, the signal line is shielded and protected to avoid mutual interference between the signals of the twisted wire pairs, further ensuring the stability and consistency of signal transmission.
[0021] The above-described embodiments do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the above-described embodiments shall be included in the scope of protection of this technical solution.
