[0002] Large-volume parenteral solutions refer to sterile liquid preparations with a volume of 50 ml or more that are directly administered intravenously. Common examples include glucose injection and sodium chloride injection. Packaging options include glass bottles, plastic bottles, and soft bags, with various specifications, and they are widely used in various hospital departments. Storage boxes are used to preserve large-volume parenteral solutions; their light-protected design prevents chemical reactions with photosensitive components and facilitates drug management and classification.
[0003] Large-volume infusion storage boxes generally consist of an outer shell, a storage section, and a dispensing section. Currently, most hospitals store large-volume infusions in cabinets, requiring a first-in, first-out approach to avoid waste. When storing large-volume infusions with a new expiration date, previously unused, expired infusions must be removed, the new infusion placed in the cabinet, and the old infusion placed outside the new one. This results in a significant waste of nursing staff's time and workload each day, ultimately affecting the storage efficiency of the device. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an automatic first-in-first-out (FIFO) storage box for large-volume infusions. It aims to improve the existing technology in which most hospitals store large-volume infusions in cabinets and follow the first-in-first-out principle. When storing infusions with a new expiration date, it is necessary to move infusions with an old expiration date, which is time-consuming and increases the workload of nursing staff, thus affecting storage efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic first-in-first-out (FIFO) storage tank for large-volume infusions, comprising an outer shell, a rotating rod rotatably connected inside the outer shell, a mounting bracket fixedly connected to one side of the outer wall of the rotating rod rotatably, a rotating rod slidably connected inside the mounting bracket, a sliding plate slidably connected to one side of the outer wall of the rotating rod rotatably, a partition slidably connected to one side of the outer wall of the rotating rod rotatably, an adjusting component for adjusting the position of the mounting bracket installed inside the rotating rod rotatably, a push rod slidably connected inside the rotating rod rotatably, and a connecting component for releasing the limit is installed at one end of the push rod;
[0006] The adjustment component includes a limiting block, one side of the outer wall of the limiting block is fixedly connected to the inside of the housing, one side of the outer wall of the mounting bracket is fixedly connected to a mounting block, one end of the mounting block is fixedly connected to the inside of the rotating rod, multiple slots are opened inside the limiting block, a locking block is slidably connected inside the limiting block, one side of the outer wall of the locking block is fixedly connected to a spring, one end of the spring is fixedly connected to the inside of the mounting block.
[0007] Furthermore, the connecting assembly includes a connecting rod, one side of the outer wall of the connecting rod is fixedly connected to the inside of the pressing rod, one end of the connecting rod is fixedly connected to one side of the outer wall of the locking block, one side of the outer wall of the connecting rod is slidably connected to the inside of the rotating rod, and the other side of the outer wall of the connecting rod is slidably connected to the inside of the mounting block.
[0008] Furthermore, a cover plate is rotatably connected inside the outer casing, and a buckle is fixedly connected to one side of the outer wall of the outer casing.

[0013] Furthermore, a baffle is fixedly connected inside the outer shell, and the baffle is used to block the large infusion bottle.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, by cooperating with structures such as rotating rod, mounting bracket and sliding plate, the storage box is designed with a multi-layered inclined descending track, realizing the effect of automatic first-in-first-out storage of large-volume infusions. When large-volume infusions are taken out, the large-volume infusions placed on the outermost side first will be taken out first, and the newly placed large-volume infusions will be placed inside. This solves the problem in the prior art that when placing new-expiration-period infusions, it is necessary to move the old-expiration-period infusions, which is time-consuming and increases the nursing workload, thus affecting the storage efficiency. This improves the practicality of the device.
[0016] 2. In this utility model, when the large-volume infusion slides off the mounting frame, the buffer device composed of the damping rod and the spring plays a buffering role, preventing the medicine from being damaged by collision. At the same time, the shock-absorbing pad reduces the impact of the medicine bottle and also prevents the medicine from flying out of the dispensing port. Through the above combination, the problem that existing devices are mostly composed of hard materials, when the large-volume infusion medicine bottle is fragile, is easy to break, which will affect the use of the large-volume infusion, is solved, thus improving the practicality of the device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1 - Figure 4This utility model provides an embodiment of an automatic first-in-first-out (FIFO) storage box for large-volume infusions, comprising an outer shell 1 that provides support and protection for internal components. A rotating rod 7 is rotatably connected inside the outer shell 1, serving as the mounting base for a mounting frame 10. Rotation allows the angle of the mounting frame 10 to be changed, thus accommodating large-volume infusion bottles of different sizes. The mounting frame 10 is fixedly connected to one side of the outer wall of the rotating rod 7. A second rotating rod 17 is fixedly connected inside the mounting frame 10. A sliding plate 3 is slidably connected to one side of the outer wall of the second rotating rod 17, serving as a carrier for placing and sliding the large-volume infusions, allowing them to move naturally. The rotating rod 17 is designed to ensure that the first medication placed in is retrieved first. A partition 9 is slidably connected to one side of the outer wall of the rotating rod 17 to divide it into different areas, allowing for the separate placement of different types or sizes of large-volume infusions to prevent confusion and collisions. An adjustment component for adjusting the position of the mounting bracket 10 is installed inside the rotating rod 17. A push rod 6 is slidably connected inside the rotating rod 17, with a connection component for releasing the limit at one end. The adjustment component includes a limit block 8, fixed inside the outer casing 1, which engages with the locking block 14 through an internal slot. To limit the rotation range of the mounting bracket 10 and ensure its stable fixation after adjustment, the limiting block 8 is fixedly connected to the inside of the outer shell 1 on one side of its outer wall. A mounting block 18 is fixedly connected to one side of the outer wall of the mounting bracket 10, and one end of the mounting block 18 is fixedly connected to the inside of the rotating rod 7. Multiple slots are provided inside the limiting block 8, and a locking block 14 is slidably connected inside the limiting block 8. Under the action of the spring 12, the locking block 14 engages with the slots of the limiting block 8, thus limiting the mounting bracket 10 and ensuring that it does not rotate arbitrarily during normal use. The locking block 14 is fixedly connected to the outer wall of the mounting bracket 10 on one side of its outer wall. A spring 12 provides elastic force to the locking block 14. One end of the spring 12 is fixedly connected to the inside of the mounting block 18. The connecting assembly includes a connecting rod 13. One side of the outer wall of the connecting rod 13 is fixedly connected to the inside of the push rod 6. The push rod 6 is a manual component for operating the adjustment assembly. Medical staff can control the connecting assembly by pressing it, thereby adjusting the position of the mounting bracket 10. One end of the connecting rod 13 is fixedly connected to one side of the outer wall of the locking block 14. One side of the outer wall of the connecting rod 13 is slidably connected to the inside of the rotating rod 7. The other side of the outer wall of the connecting rod 13 is slidably connected to the inside of the mounting block 18.
[0026] Reference Figure 1 and Figure 5The outer casing 1 has a rotatable cover plate 2 inside, which provides some light protection to prevent the quality of the large-volume infusion from being affected by light. A buckle 19 is fixedly connected to one side of the outer wall of the outer casing 1 to lock or unlock the cover plate 2, ensuring that the cover plate 2 is secure when closed and preventing accidental opening during normal use or handling. The buckle 19 is internally slidably connected to one side of the outer wall of the cover plate 2. A damping rod 11 is fixedly connected inside the outer casing 1. During the sliding of the large-volume infusion bottle, its damping characteristics slow down the descent speed of the connecting plate 15, thereby reducing the impact force on the bottle and preventing damage from collisions, ensuring the safety of the medicine. To ensure the integrity and availability of the system, a connecting plate 15 is fixedly connected to the output end of the damping rod 11. A spring 16 is fitted onto the damping rod 11 and works in conjunction with it to further enhance the buffering effect. One end of the spring 16 is fixedly connected to the lower surface of the connecting plate 15. A shock-absorbing pad 4 is fixedly connected to the upper surface of the connecting plate 15 and comes into direct contact with the large infusion bottle. Its soft material can effectively disperse the impact force of the bottle. The shock-absorbing pad 4 plays a buffering and protective role. A baffle 5 is fixedly connected inside the outer shell 1. The baffle 5 is used to block the large infusion bottle and prevent it from sliding out of the storage box when it rolls on the slide plate 3.
[0027] Working principle: When it is necessary to adjust the distance between the mounting brackets 10 to accommodate different specifications of large-volume infusions, by pressing the actuating lever 6, the actuating lever 6 slides inward, causing the connecting rod 13 to slide inside the rotating lever 7 and the mounting block 18. The movement of the connecting rod 13 causes the locking block 14 to overcome the elastic force of the spring 12 and slide in the slot of the limiting block 8, thereby releasing the limiting relationship between the locking block 14 and the current slot. At this time, the rotating lever 7 can be rotated, and the mounting bracket 10 rotates with the rotating lever 7, and the mounting block 18 also rotates accordingly. When the mounting bracket 10 rotates to the appropriate position, the actuating lever 6 is released, and the elastic force of the spring 12 causes the locking block 14 to re-lock into the corresponding slot of the limiting block 8, thus completing the process. The mounting bracket 10 is now fixed in place. When placing the large-volume infusion, the large-volume infusion bottle is placed on the slide plate 3. Due to the certain tilt angle of the slide plate 3, the large-volume infusion bottle will roll to one side under the action of gravity and then fall onto the second slide plate 3. This process is repeated until the large-volume infusion bottle finally falls onto the shock-absorbing pad 4. The shock-absorbing pad 4 plays a buffering role. At the same time, the spring 16 and damping rod 11 below it further buffer the bottle and prevent it from being damaged by collision. Finally, when it is necessary to remove the large-volume infusion, the outermost bottle is the one that was placed first, and the bottles that were placed later are inside. This follows the principle of first-in, first-out, and also reduces the workload of nursing staff.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
