Description

Technical Field

[0001] This utility model relates to the field of medical tube transport technology, and more specifically, to a single-branch medical tube retrieval and placement rack. Background Technology

[0002] A tube dropper is a device used to transfer medical tubes. It includes a frame with multiple parallel slides at an angle. The medical tubes in each slide slide down to the tube receiving position under the action of gravity, and then are picked up by the tube receiving mechanism for further processing.

[0003] However, because the caps of medical tubes have slightly convex brims, in the same slide, the brims of the caps of the lower medical tubes will overlap under the brims of the adjacent medical tubes above. Therefore, when the first row of medical tubes at the bottom is clamped vertically by the tube receiving mechanism, it is easy to cause the second row of medical tubes above to be lifted up as well. This causes the second row of medical tubes to detach from the slide and scatter on the tube dropper, affecting the transfer process of the medical tubes. Utility Model Content

[0030] Please see Figures 1-6 As shown, the main body of this embodiment is a single-tube retrieval and placement frame for medical tubes, including an inclined frame 1. The frame 1 has multiple parallel slides 2, which extend along the inclined direction of the frame 1. The lower end of the frame 1 is provided with a tube retrieval mechanism for gripping medical tubes 3, and also includes a blocking member that spans above all the slides 2. Both ends of the blocking member are fixedly connected to the two sides of the frame 1 by a first fixing member 4 and a second fixing member 5, respectively. A tube retrieval space 6 is left between the blocking member and the lower end of each slide 2 for the tube retrieval mechanism to grip a single medical tube 3.

[0031] The medical tubes 3 within the tube retrieval space 6 are in the first row, while the blocking member is positioned directly above the second row of medical tubes 3. When the tube retrieval mechanism grasps the medical tubes 3 within the tube retrieval space 6, the cap rim 25 of the first row of medical tubes 3 overlaps below the cap rim 25 of the second row of medical tubes 3. Therefore, when the first row of medical tubes 3 located below is lifted vertically by the tube retrieval mechanism, the second row of medical tubes 3 is also lifted and moves vertically. Once the second row of moving tubes reaches the corresponding height, the blocking member prevents the second row of medical tubes 3 from continuing to move upward, thereby preventing the second row of medical tubes 3 from detaching from the slide 2 and avoiding the second row of medical tubes 3 from scattering. On the tube dropper, when the blocking member abuts against the top of the cap of the second row of medical tubes 3, the first row of medical tubes 3 continues to move upward and generates an upward thrust, causing the top of the cap of the second row of medical tubes 3 to slide relative to the blocking member. This causes the cap rim 25 of the first row of medical tubes 3 to detach from the cap rim 25 of the second row of medical tubes 3, allowing the first row of medical tubes 3 to continue moving upward until it is completely detached from the slide 2. Then, it is transferred by the tube retrieval mechanism to the corresponding position for further processing, effectively preventing the adjacent second row of medical tubes 3 from being lifted up along with the first row of medical tubes 3 when the tube retrieval mechanism clamps or lifts them vertically. After the first row of medical tubes 3 is transferred out of the tube retrieval space 6, the second row of medical tubes 3 falls back into the slide 2 under the action of gravity and slides down the slide 2 into the tube retrieval space 6 to become the first row of medical tubes 3, waiting for subsequent retrieval by the tube retrieval mechanism.

[0032] Furthermore, the blocking element includes an elastic rope 7 that spans vertically above all the slides 2, with both ends of the elastic rope 7 fixed to the frame 1 by the first fixing member 4 and the second fixing member 5, respectively.

[0033] The elastic rope 7 effectively cushions the impact of the second row of medical tubes 3 moving vertically upward. If the blocking member is a rigid baffle, the caps of the second row of medical tubes 3 may collide directly with the blocking member, causing damage to the caps of the second row of medical tubes 3. In addition, the limited contact area between the top of the cap of the second row of medical tubes 3 and the elastic rope 7 effectively reduces the friction between the top of the cap of the second row of medical tubes 3 and the elastic rope 7, which is conducive to the relative sliding of the two and thus facilitates the separation of the cap rim 25 of the first row of medical tubes 3 from the cap rim 25 of the second row of medical tubes 3.

[0034] Furthermore, a tensioning mechanism for adjusting the tension of the elastic rope 7 is provided on the outer side of the second fixing member 5; one end of the elastic rope 7 passes through the inner side of the second fixing member 5 to the outer side of the second fixing member 5 and is connected to the tensioning mechanism.

[0035] During the long-term blocking process, the elastic rope 7 will gradually loosen and its tension will gradually decrease. However, the elastic rope 7 needs to be taut during the blocking process to achieve effective blocking and impact buffering. Therefore, the tensioning mechanism is used to tighten the elastic rope 7 to ensure its taut state.

[0036] Furthermore, the tensioning mechanism includes a housing 8 fixedly disposed on the outside of the second fixing member 5, a winding post 9 rotatably connected to the outside of the second fixing member 5, one end of the elastic rope 7 passing through the inside of the second fixing member 5 to the outside of the second fixing member 5 and fixedly connected to the winding post 9, one end of the winding post 9 being disposed inside the housing 8 and fixedly connected to a worm gear 10, and a worm 11 rotatably connected inside the housing 8, one end of the worm 11 extending to the outside of the housing 8 and fixedly connected to an operating handle 12.

[0037] Specifically, rotating the operating handle 12 drives the worm gear 11 to rotate, which in turn drives the worm wheel 10 to rotate, thereby causing the elastic rope 7 to wind onto the winding post 9 and tightening the elastic rope 7. In addition, the worm wheel 10 and worm gear 11 mechanism has an effective self-locking function, meaning that the worm wheel 10 can only be driven to rotate by the worm gear 11, and the worm gear 11 cannot be driven to rotate by the worm wheel 10. Therefore, after the tensioning mechanism is adjusted, it can automatically lock the tension of the elastic rope 7.

[0038] Furthermore, a limiting seat 13 is fixedly installed on the frame 1, and the elastic rope 7 passes through and slides inside the limiting seat 13.

[0039] The limiting seat 13 can ensure that the elastic rope 7, which is in a taut state, remains straight and prevents the slight deformation caused by the tautness from causing the elastic rope 7 to bend.

[0040] Furthermore, a moving mechanism is provided on the exterior of the lower end of the frame 1, and the tube retrieval mechanism is fixedly connected to the moving mechanism. The tube retrieval mechanism is located above the tube retrieval space 6. The frame 1 is provided with a retrieval channel 14 leading to the lower part of the frame 1, and the port of the retrieval channel 14 is collinear with all tube retrieval spaces 6.

[0041] Furthermore, the moving mechanism includes a first linear guide rail 15 disposed outside the lower end of the frame 1, and the two ends of the first linear guide rail 15 are fixedly connected to the frame 1 through side plates 17; the sliding direction of the first slider 16 of the first linear guide rail 15 is parallel to the collinear direction of the tube retrieval space 6; the tube retrieval mechanism is fixed on the first slider 16.

[0042] Furthermore, the tube retrieval mechanism includes a second linear guide rail 18 fixed on the first slider 16. The second linear guide rail 18 is vertically arranged, and the sliding direction of the second slider 19 of the second linear guide rail 18 is perpendicular to the collinear direction of the tube retrieval space 6. A mounting plate 20 is fixedly connected to the second slider 19. A vacuum generator 21 is fixedly connected to the top surface of the mounting plate 20, and a suction cup 22 with a size matching the cap of the medical tube 3 is fixedly connected to the bottom surface of the mounting plate 20. The suction cup 22 is located above the tube retrieval space 6. One end of the vacuum generator 21 is connected to a pipe 23, and one end of the pipe 23 extends to the bottom of the mounting plate 20 and communicates with the suction cup 22.

[0043] The first linear guide 15 can adjust the position of the tube retrieval mechanism, facilitating the retrieval of medical tubes 3 from different slides 2. The second linear guide 18 controls the vertical movement of the mounting plate 20. When the mounting plate 20 moves downwards a certain distance, the suction cup 22 contacts the caps of the first row of medical tubes 3 in the tube retrieval space 6. Then, the vacuum generator 21 creates a vacuum in the suction cup 22, thereby adsorbing the first row of medical tubes 3. The second slider 19 of the second linear guide 18 then moves upwards, lifting the medical tube 3. The first slider 16 of the first linear guide 15 then slides, moving the medical tube 3 above the port of the retrieval channel 14. Finally, the vacuum generator 21 eliminates the vacuum in the suction cup 22, causing the medical tube 3 to detach from the suction cup 22, fall into the retrieval channel 14, and drop below the frame 1, entering the next processing stage.

[0044] Furthermore, the frame 1 is also provided with a baffle plate 24 corresponding to the slide 2.

[0045] The baffle plate 24 blocks and straightens the first row of medical tubes 3 to prevent the medical tubes 3 from tilting and causing the suction cup 22 to not fit properly with the tube cap of the medical tube 3.

[0046] It is worth mentioning that this device also includes a controller, which is an industrial PLC. The first linear guide 15, the second linear guide 18, and the vacuum generator 21 are all electrically connected to the controller.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
