Patent number: 11925584Abstract: A medical suspension bridge includes a cross beam, a suspension pipe and a moving module. The cross beam is connected with the suspension pipe. The moving module is movably connected with the cross beam. The cross beam includes a load-bearing beam. The moving module includes a cable carrier moving plate extending to the upper portion of the load-bearing beam. The medical suspension bridge further includes a cable carrier. One end of the cable carrier is connected to the load-bearing beam, and the other end is connected to the cable carrier moving plate. Since cables such as electric wires and air pipes within a box body which needs to be moved are collectively mounted within the cable carrier, not only the routing is more tidy, but also the cables can be well protected.Type: GrantFiled: December 14, 2018Date of Patent: March 12, 2024Assignee: Maquet (Suzhou) Co., Ltd.Inventors: Bing Wei, Jiasheng Huang, Jin Xuan, Qunhua Li
