Description

Technical Field

[0001] This utility model relates to a hemodialysis auxiliary vehicle and belongs to the field of hemodialysis technology. Background Technology

[0002] Hemodialysis is a renal replacement therapy for patients with acute and chronic renal failure. It involves drawing blood from the body and passing it through a dialyzer composed of numerous hollow fibers. The blood and an electrolyte solution with similar concentrations to those in the body exchange substances through diffusion, ultrafiltration, adsorption, and convection within the hollow fibers, removing metabolic waste, maintaining electrolyte and acid-base balance, and simultaneously removing excess water. The purified blood is then returned to the body. In this complex and rigorous treatment process, medical staff need to place the necessary dialysis equipment on a support cart for transport, making the hemodialysis support cart an indispensable key piece of equipment.

[0003] Although existing hemodialysis support vehicles can meet the daily delivery needs of dialysis equipment, there are still two significant shortcomings in actual clinical applications, which restrict the user experience and functional expansion: Firstly, the ease of operation needs improvement. Assistive carts are typically equipped with multiple drawers for categorizing and storing dialysis equipment. However, medical staff must manually open each drawer one by one to retrieve items. This not only increases the number of steps but also reduces the efficiency of item retrieval in emergency situations. Especially during busy periods with multiple patients waiting for dialysis, repeatedly opening and closing drawers consumes extra energy for medical staff, indirectly affecting the continuity of the workflow and thus making the assistive cart less convenient to use. Secondly, the adaptability of the operating table space is limited. The fixed dimensions of the auxiliary cart's table mean that various items taken from the drawers, such as dialysis consumables, recording forms, and temporary medical waste containers, can only be placed within a limited area. In complex clinical scenarios, such as simultaneously preparing multiple patients for dialysis, or when additional steps are needed, such as verifying medical orders or performing simple item sorting, the fixed table space often fails to meet diverse placement requirements. Stacking items not only leads to confusion and increases the risk of misuse, but also prevents flexible adjustments to the functional zoning of the table according to the operating habits and actual needs of medical staff. This significantly limits the auxiliary cart's adaptability to different clinical scenarios, hindering its full auxiliary function and thus limiting its use. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a hemodialysis auxiliary vehicle, which overcomes the shortcomings of the prior art and effectively solves the problems of insufficient ease of use and limitations in the use of the auxiliary vehicle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A hemodialysis auxiliary vehicle includes a base frame, with casters at the four corners of the lower end of the base frame and fixed brackets at the four corners of the upper end of the base frame. An operating table is fixed to the upper end of the four fixed brackets, with a handle fixed to one end of the operating table, a sliding groove on one side of the operating table, and a limit groove in the middle of the operating table. The inner wall of the limiting groove is provided with a connecting structure, and the connecting structure is provided with two drawers; the connecting structure can slide the two drawers in opposite directions along the width of the limiting groove so that the two drawers can be opened at the same time.

[0006] Preferably, the connecting structure includes two drawers, each with a stabilizing groove in the middle of its lower side. Each stabilizing groove has a slider slidably connected to the inner walls on both sides. The outer surfaces of the four sliders are rotatably connected to two connecting brackets, and the middle of the two connecting brackets is rotatably connected to a stabilizing rod.

[0007] Preferably, the outer surfaces of the two drawers are slidably connected to the inner walls on both sides of the limiting groove, and the vertical cross-section of each drawer is T-shaped. The two stabilizing grooves pass through the middle of the lower side of the two drawers, and the outer surface of each slider is slidably connected to the inner wall on one side of each stabilizing groove. The vertical cross-section of each slider is T-shaped.

[0008] Preferably, the outer surfaces of the four sliders are rotatably connected to the two ends of the two connecting frames, the two connecting frames are distributed in a cross pattern, the middle of the two connecting frames are rotatably connected to the outer surface of the stabilizer, the upper end of the stabilizer is fixed to the middle of the lower side of the operating table, and the vertical section of the stabilizer is T-shaped.

[0009] Preferably, each of the two drawers has a fixing block fixed on its adjacent side, and each of the two fixing blocks has a connecting frame rotatably connected to its adjacent end. The other end of each of the two connecting frames is rotatably connected to a support frame. The support frame has a through groove in the middle, and an operating plate is fixed to one end of the support frame.

[0010] Preferably, the two fixing blocks are fixed at opposite ends to the two drawers at adjacent ends, the two fixing blocks are rotatably connected to the two connecting frames at opposite ends, and the two connecting frames are rotatably connected to one end of the support frame.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Example 1 This utility model embodiment provides a hemodialysis auxiliary vehicle.

[0017] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes a base frame 1, with casters 2 at each of the four corners of the lower end of the base frame 1, and fixed brackets 3 at each of the four corners of the upper end of the base frame 1. An operating table 4 is fixed to the upper end of the four fixed brackets 3, and a handle 5 is fixed to one end of the operating table 4. A sliding groove 6 is provided on one side of the operating table 4, and a limiting groove 7 is provided in the middle of the operating table 4. A connecting structure is provided on the inner wall of the limiting groove 7, and the connecting structure includes two drawers 8. A stabilizing groove 9 is provided in the middle of the lower side of each of the two drawers 8. A slider 10 is slidably connected to the inner walls on both sides of each stabilizing groove 9. Two connecting brackets 11 are rotatably connected to the outer surface of the four sliders 10, and a stabilizing rod 12 is rotatably connected to the middle of the two connecting brackets 11.

[0018] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that the outer surfaces of the two drawers 8 are slidably connected to the inner walls on both sides of the limiting groove 7, and the vertical cross-section of each drawer 8 is T-shaped. The two stabilizing grooves 9 pass through the middle of the lower side of the two drawers 8. The outer surface of each slider 10 is slidably connected to the inner wall on one side of each stabilizing groove 9, and the vertical cross-section of each slider 10 is T-shaped. The outer surfaces of the four sliders 10 are rotatably connected to the two ends of the two connecting frames 11. The two connecting frames 11 are distributed in a cross pattern. The middle of the two connecting frames 11 is rotatably connected to the outer surface of the stabilizing rod 12. The upper end of the stabilizing rod 12 is fixed to the middle of the lower side of the operating table 4, and the vertical cross-section of the stabilizing rod 12 is T-shaped.

[0019] In use, when a medical staff member pulls one of the drawers 8, the drawer 8 slides smoothly under the guidance and limiting action of the inner wall of the limiting groove 7. Simultaneously, the stabilizing groove 9 in the middle of the lower side of the drawer 8 drives the two sliders 10 slidably connected inside to move synchronously. Since the four sliders 10 are interconnected by two cross-connecting frames 11, and the middle of the two connecting frames 11 is rotatably connected to the outer surface of the stabilizing rod 12 fixed in the middle of the lower side of the operating table 4, these two moving sliders 10, with the help of the linkage of the cross connecting frames 11 and under the support and limiting action of the stabilizing rod 12, drive the other two sliders 10 to move synchronously in opposite directions. Through this cooperative transmission structure, the four sliders 10 form a synchronous motion mechanism, enabling the pulled drawer 8 to drive the other drawer 8 to open synchronously. This achieves the effect of synchronous opening, eliminating the need for medical staff to open each drawer 8 individually, significantly reducing operating steps and thus improving the ease of use of the auxiliary cart.

[0020] Example 2 Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on Embodiment 1, the function of dynamically expanding the operating space has been added; Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that two drawers 8 are fixed with fixing blocks 13 on their adjacent sides, and two fixing blocks 13 are rotatably connected to connecting frames 14 at their adjacent ends. The other ends of the two connecting frames 14 are rotatably connected to support frames 15. A through groove 16 is provided in the middle of the support frame 15. An operating plate 17 is fixed to one end of the support frame 15. The two fixing blocks 13 are fixed to the adjacent sides of the two drawers 8 at their distancing ends. The two fixing blocks 13 are rotatably connected to the distancing ends of the two connecting frames 14 at their adjacent ends. The two connecting frames 14 are rotatably connected to one end of the support frame 15 at their adjacent ends. The outer surface of the stabilizing rod 12 is slidably connected to the inner wall of the through groove 16. The through groove 16 passes through the middle of the support frame 15. One end of the support frame 15 is fixed to one side of the operating plate 17. The outer surface of the operating plate 17 is slidably connected to the inner wall of the slide groove 6. The vertical section of the support frame 15 is L-shaped.

[0021] In use, when a medical staff member pulls one of the drawers 8, the drawer 8, through the coordinated action of the slider 10 and the connecting frame 11, moves the other drawer 8 synchronously under the support and limitation of the stabilizing rod 12. As the two drawers 8 slide synchronously, the two fixing blocks 13 fixed on their adjacent sides also move synchronously, thereby driving the connecting frame 14, which is rotated and connected at their adjacent ends, to create a linkage. The other ends of the two connecting frames 14 are rotatably connected to the support frame 15. At this time, the support frame 15 maintains stable movement by relying on the sliding cooperation between the through groove 16 in the middle and the stabilizing rod 12, and finally drives the operating plate 17 fixed at the other end to unfold synchronously under the guidance and limitation of the sliding groove 6. This linkage structure realizes the dynamic expansion effect of the operating space. Medical staff can place various tools for hemodialysis on the expanded table in sections according to actual needs, which not only avoids the confusion caused by the stacking of items, but also flexibly adapts to the placement needs of different operating scenarios, thereby improving the practicality of the auxiliary cart.
