[0028] In medical equipment such as medical pendant towers and suspension bridges, the infusion stand arm is a key functional module, responsible for suspending infusion bags (bottles), integrating cable pipelines, and adjusting the infusion height.

[0029] Traditional medical infusion stand arms typically use a flip-lock cable tray structure to open and close the cable channel and fix it. While this method can meet basic functional requirements, it has the risks of complex assembly processes and accidental opening of the cable tray leading to cable detachment in practical applications.

[0030] This utility model proposes a support arm structure, which aims to solve the problems of complex assembly and easy loosening of traditional flip-locking structures.

[0031] Please see Figure 1 In one embodiment of this utility model, the support arm structure 100 is used in a medical pendant bridge. The support arm structure 100 includes a main body 1 and a limiting component 2. The main body 1 includes a first mounting part 11 and a second mounting part 12, and a connecting section 13 connecting the first mounting part 11 and the second mounting part 12. The first mounting part 11 is used to connect to an infusion stand, and the second mounting part 12 is used to connect to a medical pendant bridge. A cable gathering groove 14 is provided on the outer wall of the connecting section 13. The cable gathering groove 14 is used to bind at least one strand of wire. The limiting component 2 is disposed on the connecting section 13 corresponding to the opening of the cable gathering groove 14. The limiting component 2 includes a limiting part 21, which is disposed in the middle of the cable gathering groove 14 to intermittently connect the opening of the cable gathering groove 14 to the inlet 15 and the outlet 16. The inlet 15 is connected to the outlet 16 through the cable gathering groove 14.

[0032] The technical solution of this utility model adopts the support arm structure 100, which includes a main body 1 and a limiting component 2. The main body 1 includes a first mounting part 11, a second mounting part 12, and a connecting section 13 connecting the first mounting part 11 and the second mounting part 12. The first mounting part 11 is used to connect to the infusion stand, and the second mounting part 12 is used to connect to the medical pendant bridge. The outer wall of the connecting section 13 is provided with a cable gathering groove 14, which is used to bind at least one strand of wire. The limiting component 2 is disposed on the connecting section 13 corresponding to the groove of the cable gathering groove 14. The limiting component 2 includes a limiting part 21, which is disposed in the middle of the cable gathering groove 14 to intermittently separate the groove of the cable gathering groove 14 into an inlet 15 and an outlet 16. The inlet 15 is connected to the outlet 16 through the cable gathering groove 14. With this configuration, the wire harness can be placed in the wire harness 14 and limited by the limiting component 2 through the cooperation of the wire harness 14 and the limiting component 2, thereby constraining it on the support arm structure 100. The limiting part 21 is set in the middle of the wire harness 14, forming an intermittent slot through physical separation. It does not rely on the complex moving parts of the traditional flip-and-lock structure, reducing the number of parts and lowering the assembly complexity and manufacturing cost.

[0033] In some embodiments, the limiting component 2 can be fixed, such as by bonding or welding; or it can be detachable, such as by snap-fit ​​or bolt installation.

[0034] Of course, the setting of the limiting part 21 is not specifically limited in this embodiment. For example, it can be a plate, a frame, etc.

[0035] Specifically, in one embodiment, the limiting part 21 includes a cable tray 211, which is fitted into the cable tray groove 14. The cable tray 211 is provided with a cable passage groove 212, which is also provided within the cable tray groove 14. The cable inlet 15 communicates with the cable outlet 16 through the cable passage groove 212. With this configuration, when the cable bundle needs to be passed from the cable inlet 15 into the cable tray groove 14 and guided to the cable outlet 16, the cable bundle can be laid along the cable passage groove 212 of the cable tray 211. The cable passage groove 212 provides a clear path for the cable bundle, reducing crossings and confusion between cable bundles. Simultaneously, the cable tray 211 being fitted into the cable tray groove 14 ensures a stable connection between the limiting part 21 and the cable tray groove 14, further enhancing the stability and reliability of the cable bundle restraint.

[0036] Please see Figure 2 and Figure 3Furthermore, in one embodiment, the cable tray 211 includes an overlapping portion 2111 and an enclosing portion 2112 that are interconnected. The overlapping portion 2111 and the enclosing portion 2112 define the cable passage 212. The overlapping portion 2111 overlaps the connecting segment 13, and the enclosing portion 2112 is disposed within the cable tray 14. Thus, the overlapping design between the overlapping portion 2111 and the connecting segment 13 facilitates the installation and disassembly of the cable tray 211, while also ensuring a stable installation of the cable tray 211 within the cable tray 14. The enclosing portion 2112 enhances the binding effect of the cable tray 14 on the cable bundle, resulting in a neater and more orderly arrangement of the cable bundle within the cable tray 14.

[0037] In this embodiment, the installation method of the enclosure 2112 is not specifically limited, such as snap-fit.

[0038] Specifically, in one embodiment, the enclosure portion 2112 includes a first sidewall 2114 and a second sidewall 2115 connected to each other. The first sidewall 2114 is snapped onto an inner sidewall of the cable tray 14, and the second sidewall 2115 extends toward another opposite inner sidewall of the cable tray 14 and is spaced apart from it to form the through groove 2113. This configuration enhances the connection strength between the enclosure portion 2112 and the cable tray 14, reducing the likelihood of the enclosure portion 2112 shaking or falling off during use. The spacing between the second sidewall 2115 and the other opposite inner sidewall of the cable tray 14 forms the through groove 2113, facilitating the smooth entry of the cable harness.

[0039] In one embodiment, the enclosure portion 2112 has a through groove 2113 on the side facing the opening of the cable tray 14, so that the inlet 15 communicates with the outlet 16 through the through groove 2113. Thus, the through groove 2113 allows the cable bundle to smoothly enter the cable tray 14 from the through groove 2113, and both ends of the cable bundle naturally exit from the inlet 15 and the outlet 16, without the need for complex winding or adjustment, improving the efficiency of cable bundle storage.

[0040] To improve the stability of the wire harness, in one embodiment, two enclosing portions 2112 are provided. The ends of the two first sidewalls 2114 away from the second sidewalls 2115 are connected to the overlapping portion 2111. The two second sidewalls 2115 are arranged opposite each other to create the through groove 2113. Thus, the design of the two enclosing portions 2112 enhances the stability of the overall structure, thereby improving the wire harness's fixation effect. Simultaneously, the opposite arrangement of the two second sidewalls 2115, with the interval between them forming the through groove 2113, provides sufficient space for the wire harness to enter and exit, ensuring smooth placement of the wire harness.

[0041] The connection between the first sidewall 2114 and the overlapping part 2111 is fixed, such as by bonding or welding.

[0042] In one embodiment, a mating protrusion 2116 is provided on the first sidewall 2114, and a mating recess 2117 is provided on the inner sidewall of the cable tray 14. The mating protrusion 2116 engages with the mating recess 2117. Thus, the engagement design of the mating protrusion 2116 and the mating recess 2118 not only further stabilizes the connection between the enclosure 2112 and the cable tray 14, but also improves the convenience and accuracy of installation. During installation, the operator only needs to align the mating protrusion 2116 with the mating recess 2118 and push it in to quickly fix the enclosure 2112 to the cable tray 14 without the need for additional screws or other fasteners, saving installation time and costs. Furthermore, when the enclosure 2112 needs repair or replacement, the operator can easily and quickly remove it from the cable tray 14. Furthermore, the tight fit between the mating protrusion 2116 and the mating recess 2117 can reduce the entry of dust, moisture and other impurities into the cable tray 14, protect the cable harness from damage and extend its service life.

[0043] It should be explained that the mating protrusion 2116 and the mating recess 2117 can be connected by using a block and slot configuration.

[0044] In one embodiment, the connection between the first sidewall 2114 and the second sidewall 2115 is elastically configured. This allows for appropriate elastic deformation at the connection, thereby changing the size of the through groove 2113. When inserting a wire harness, the harness can be pushed from below the second sidewall 2115 through the through groove 2113 into the wire guide groove 212. Due to tension, the second sidewall 2115 can receive the wire harness after it has fully entered the wire guide groove 212, making the process simple and convenient.

[0045] It should be noted that the first sidewall 2114 and the second sidewall 2115 can be provided as elastic sheets or elastic plates to give them an elastic effect.

[0046] In one embodiment, a groove 2118 is provided on at least one side of the connection between the first sidewall 2114 and the second sidewall 2115, allowing the first sidewall 2114 to move relative to the second sidewall 2115. Thus, the groove 2118 increases the elasticity at the connection between the first sidewall 2114 and the second sidewall 2115, thereby improving the flexibility of the through-slot 2113 in terms of dimensional changes. When the wire harness is pushed into the through-slot 212, the second sidewall 2115 has a larger elastic deformation space, thereby better securing the wire harness.

[0047] In this embodiment, preferably, the groove 2118 is formed at the connection between the first sidewall 2114 and the second sidewall 2115, so that the second sidewall 2115 has a better rebound effect.

[0048] In one embodiment, both the first mounting part 11 and the second mounting part 12 are provided with mounting holes 17. The mounting holes 17 are used to connect with corresponding components by fasteners. In this way, the support arm structure 100 can be easily installed on the medical pendant bridge through the mounting holes 17. The mounting holes 17 also facilitate the adjustment of the position and angle of the support arm structure 100 to meet the suspension requirements of different medical devices, thereby improving the flexibility and applicability of the medical pendant bridge.

[0049] It should be added that, in use, the enclosure 2112 is first snapped into the cable tray 14 for installation, and then the wire harness is squeezed toward the through groove 2113 by squeezing, and then placed into the through groove 212. At this time, the second side wall 2115 is subjected to elastic force due to the squeezing of the wire harness. When the wire harness is completely placed in the through groove 212, the second side wall 2115 is no longer squeezed and rebounds, limiting the wire harness and completing the fixing of the wire harness.

[0050] It should be explained that the size of the through groove 2113 is at least sufficient to allow a wire harness to be placed in the through groove 212 without falling off.

[0051] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
