Description

Technical Field

[0001] This application relates to the field of expiration date management technology, and in particular to a shelf that facilitates expiration date management. Background Technology

[0002] Managing the expiration dates of medications is a core aspect of pharmacy management in medical institutions, directly impacting medication safety. This is particularly important in intravenous drug preparation centers. Therefore, establishing an efficient, reliable, and easy-to-use "first-in, first-out" (FIFO) management process is crucial, ensuring that medications with earlier production dates are prioritized for distribution or use.

[0003] Currently, multi-layered fixed shelves or cabinets are commonly used for storing medicines in various scenarios. Traditional placement methods mainly rely on manual management and visual inspection to control expiration dates. In practice, staff need to place newly received medicines behind or above existing medicines, and consciously take medicines that were stored earlier from the front, lower, or outer shelves when dispensing or preparing medicines.

[0004] However, this method relies heavily on human initiative in practice. A perfect "first-in, first-out" process depends heavily on each operator's sense of responsibility, memory, and awareness of strictly adhering to procedures. In busy work environments, especially during peak medication dispensing periods, staff may prioritize speed and overlook the order of medication dispensing, taking medication directly from the outermost, topmost, or most easily accessible location. This results in earlier batches of medication being left behind, eventually leading to expired inventory. Utility Model Content

[0016] To address the problem that the current practice of storing pharmaceuticals using multi-layered fixed shelves or cabinets necessitates a high degree of reliance on manual oversight for achieving "first-in, first-out" expiration date control, this application offers the following advantages: The core of this shelf design, which facilitates expiration date management, lies in its combination of inclined storage layers and movable supports, utilizing gravity to automatically draw medications to the lower side. Combined with an adjustable-spacing partition system (slides), it allows for directional and zoned storage of medications of different specifications. For example, N partitions create N+1 slides between two side panels.

[0017] In practical use, a medicine can be placed through a slide, and the medicines are arranged so that the medicines with earlier production dates are closer to the first side. Then, the operator is required to take the medicine from the first side each time, and when replenishing the inventory, the medicine can only be placed from the second side.

[0018] This shelf design, which facilitates expiration date management, enforces a "first-in, first-out" system. Medications naturally slide towards the lower side of the shelf (the first side) under gravity, ensuring that medications placed earlier are used first. This facilitates expiration date management and effectively prevents medications from expiring due to prolonged storage.

[0019] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. These will be further described in detail below with reference to figures. Attached Figure Description

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it may be directly or indirectly located on that other component. When a component is referred to as "connected to" another component, it may be directly or indirectly connected to that other component. The terms "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate orientations or positions based on the accompanying drawings, and are for ease of description only, and should not be construed as limiting the technical solution. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality" means two or more, unless otherwise explicitly defined.

[0025] In the management of drug expiration dates in intravenous drug preparation centers, the "first-in, first-out" (FIFO) management process is followed, meaning that each time medication is retrieved, the medication with the earliest production date should be taken first. However, the current widespread use of multi-layered fixed shelves or cabinets for storing medications means that achieving "first-in, first-out" expiration date control relies heavily on human discretion.

[0026] Therefore, refer to Figures 1-7 This application discloses a shelf that facilitates expiration date management.

[0027] In the embodiments of this disclosure, such as Figure 1 As shown, the shelf for shelf-life management includes a support body 100 and at least one shelf 200 disposed on the support body 100.

[0028] Among them, such as Figure 2 and Figure 3 As shown, the shelf 200 includes a bottom support 300, a rotating support 400, a barrier 500, a spacer 600, and an adjustment structure 700. The bottom support 300 is connected to the support body 100 and has a support structure with opposing first sides 301 and second sides 302. The first side 301 is lower than the second side 302 to tilt the support structure. Several rotating support members 400 are distributed on the support structure, mainly for supporting the movement of the bottom of the medicine. The barrier 500 includes side panels 501 on both sides of the bottom support 300, which are generally located on both sides of the bottom support 300 but are fixedly connected to the support body 100 by screws or other means; and a limiting member 502 in the direction of the first side 301, extending from one side panel 501 to the other side panel 501. A spacer 600 is disposed between two side baffles 501 and extends from the first side 301 to the second side 302. Multiple spacers 600 are provided and arranged along the length of the first side 301. An adjustment structure 700 is disposed on the first side 301 and the second side 302. The adjustment structure 700 is connected to the spacers 600 and is used to adjust the spacing between the spacers 600.

[0029] The core of this shelf design, which facilitates expiration date management, lies in the combination of an inclined shelf layer 200 and movable supports, utilizing gravity to automatically gather medications towards the lower side. Combined with an adjustable-spacing partition system (slides 503), it enables directional and zoned storage of medications of different specifications. For example, N number of spacers 600 create N+1 slides 503 between two side panels 501. A limiting member 502 is used to horizontally block the upper side of the first side 301 to restrict the position of the medications and prevent them from sliding off the slides 503.

[0030] In practical use, a medicine can be placed through a slide 503, and the medicines are arranged so that medicines with earlier production dates are closer to the first side 301. Then, each time the operator takes medicine, he / she is required to take medicine from the first side 301. When replenishing the inventory, medicine can only be placed from the second side 302.

[0031] First, the shelf design, which facilitates expiration date management, enforces a "first-in, first-out" system. Medications slide naturally to the lower side of shelf 200 (i.e., the first side 301) under gravity, ensuring that medications placed earlier are used first. This facilitates expiration date management and effectively prevents medications from expiring due to prolonged storage.

[0032] Secondly, the shelf design, which facilitates expiration date management, improves management efficiency. Medicines are arranged directionally along slide 503, making them easily visible and eliminating the need for manual searching and expiration date verification, thus reducing workload and the probability of errors.

[0033] Third, this shelf design, which facilitates expiration date management, is highly adaptable. The spacing of the spacers 600, which can be adjusted via the adjustable structure 700, allows for flexible division of storage space. Different width slides 503 can be set for different drug specifications to accommodate drugs of different sizes and packaging, thereby improving space utilization.

[0034] Furthermore, such as Figure 1 As shown, the support body 100 is provided with multiple storage layers 200, which are arranged along the height direction of the support body 100. By setting multiple independent, structurally identical storage layers 200 along the height direction of the support body 100, vertical space is fully utilized, significantly increasing the drug storage capacity, which is suitable for applications with large storage volumes in intravenous drug preparation centers. Furthermore, different types or expiration dates of drugs can be stored on different layers, achieving more refined zoning, layering, and classification management. Moreover, the number of layers can be increased or decreased according to actual needs to adapt to different scales of use environments, enhancing the scalability of this shelf that facilitates expiration date management.

[0035] In the embodiments of this disclosure, such as Figure 2 and Figure 3As shown, the bottom support 300 includes: a first support member 303 and a second support member 304, both of which are horizontally fixedly connected to the support body 100. The first support member 303 is located at the lower part of the first side 301, and the second support member 304 is located at the lower part of the second side 302; and a mounting member 305, which is elongated and located above the first support member 303 and the second support member 304. One end of the mounting member 305 is connected to the first support member 303, and the other end is connected to... The second support member 304 is used to tilt the mounting member 305. There are multiple mounting members 305, and the multiple mounting members 305 are arranged along the length of the first side 301. The rotating support member 400 (such as a bullseye bearing) has a rotatable support part 401. The rotating support member 400 is disposed on the mounting member 305 and arranged along the length of the mounting member 305. The support part 401 protrudes from the upper side of the mounting member 305. That is, the support structure is equivalent to being composed of the upper side or upper side of several mounting members 305.

[0036] The first support member 303 and the second support member 304, which are fixed horizontally and at different heights, provide a stable foundation for the elongated mounting member 305 above, creating a slope with an angle of inclination relative to the horizontal plane generally controlled between 4° and 10°. Multiple parallel mounting members 305 constitute the main load-bearing and guiding frame of the storage layer 200. The modular design of the main frame, composed of several mounting members 305, is simple in structure, easy to assemble, and low-cost to manufacture. It also facilitates the installation of the rotating support member 400 and makes subsequent installation and maintenance easier.

[0037] In some embodiments, the bottom support 300 has a horizontal support portion on the side near the first side 301. For example, by providing a straight horizontal segment at one end of the mounting member 305 near the first side 301, and arranging and spreading out several such horizontal segments of the mounting members 305, a horizontal support portion is formed as described above. That is, after the medicine slides to the first side 301, it is supported by the horizontal support portion in the direction of the first side 301, thus placing the medicine upright, which facilitates the retrieval of the medicine and observation during retrieval.

[0038] To further simplify the installation structure and improve the ease of maintenance of the bottom support 300, the first support member 303 and the second support member 304 are horizontally arranged rods with parallel length directions; the lower sides of both ends of the mounting member 305 are respectively provided with connecting parts 306, such as... Figure 5As shown, the connecting part 306 is provided with a U-shaped groove 307 with an opening facing downwards, and a screw hole 308 extending through the U-shaped groove 307 is provided on the side of the connecting part 306. The two U-shaped grooves 307 are respectively inserted into the first support member 303 and the second support member 304. A stud 309 is provided on the screw hole 308 and threadedly engaged with it. By rotating the stud 309, the stud 309 abuts against the first support member 303 and the second support member 304 respectively. To ensure reliable connection, the stud 309 is generally positioned below the axis of the first support member 303 and the second support member 304.

[0039] In the embodiments of this disclosure, such as Figure 5 and Figure 6 As shown, the rotating support 400 includes a shaft 402, on which a rotatable roller 404 is provided. The mounting member 305 is connected via the shaft 402 so that the roller 404 becomes a support part 401. Further, the mounting member 305 is provided with a plurality of slots 310 arranged along the length direction of the mounting member 305, and the length direction of the slots 310 extends along the width direction of the mounting member 305; the shaft 402 is embedded in the slots 310, and the shaft 402 is connected to the mounting member 305 by the tight fit between the shaft 402 and the slots 310. Furthermore, the slot 310 has a stop 312 protruding to the other side at least one side of its opening, and the slot 310 has a limiting groove 311 extending along its depth direction; the shaft 402 has a limiting protrusion 403, and when the shaft 402 is embedded in the slot 310, the limiting protrusion 403 is embedded in the limiting groove 311, and the stop 312 is located on the side of the shaft 402 away from the bottom of the slot 310. Furthermore, both ends of the shaft 402 are provided with rollers 404, and the portion of the shaft 402 located between the two rollers 404 is embedded in the slot 310. Preferably, the mounting member 305 is provided with a relief groove 313 extending along the length direction of the mounting member 305, and the shaft member 402 is also provided with a roller 404 in the middle. The roller 404 in the middle of the shaft member 402 is located in the relief groove 313. The relief groove 313 divides the slot 310 into two sections. The stop 312 can be provided only in one section of the slot 310 on one side of the relief groove 313.

[0040] The rotating support 400 is specifically configured as a structure consisting of a shaft 402 and a roller 404. The shaft 402 is fixed by embedding it into a specific groove 310 on the mounting piece 305. This fixing method is simple to install and not complex to manufacture; for example, the mounting piece 305 can be made of only plastic or nylon, resulting in lightweight and low-cost operation. The tight fit between the groove 310 and the shaft 402 (as opposed to an interference fit), the engagement of the limiting protrusion 403 and the limiting groove 311, and the anti-detachment design of the stop 312 ensure that the roller 404 does not loosen or fall off when subjected to the impact of the medicine and during long-term use. The limiting protrusion 403 is embedded in the limiting groove 311 to limit the installation of the shaft 402, preventing improper installation from causing the roller 404 to rub against the mounting piece 305 and reducing its operational efficiency. The outer cylindrical surface of the roller 404 protrudes as a support part 401 that directly contacts the medicine. The roller 404 transforms sliding friction into rolling friction, significantly reducing the resistance to the downward movement of the medicine, making the sliding smoother and easier, especially suitable for heavier medicines or medicines with uneven bottom surfaces. The rollers 404 are arranged along the length of the mounting component 305, with an additional roller 404 added in the middle of the shaft 402 and accommodated by the clearance groove 313, providing a more continuous (high-density), uniform "support surface" and preventing the medicine packaging from getting stuck in the gaps between adjacent rollers 404. Furthermore, it is easy to maintain; damaged roller 404 components can be replaced individually by removing them from the slot 310 without replacing the entire mounting component 305.

[0041] Among them, the shaft 402 can be a metal part, and the limiting protrusion 403 is formed by extruding metal wire, which is simple to manufacture and low in cost.

[0042] In the embodiments of this disclosure, such as Figure 3 , Figure 4 and Figure 7As shown, the adjustment structure 700 includes: two support rods 701, which are parallel to each other and distributed vertically, with both ends of the support rods 701 connected to the side baffles 501 on the first side 301 and the second side 302 respectively; two sliding grooves 702, which are both provided on the two ends of the spacer 600 and are slidably engaged with the support rods 701 respectively; two adjustment grooves 703, which are provided on the spacer 600; and an adjustment member 704, which is connected to the adjustment grooves 703, and the position of the adjustment grooves 703 connected to the adjustment member 704 can be adjusted in the length direction of the adjustment member 704; wherein, on the spacer 600 adjacent to the side baffles 501, one adjustment member 704 is provided on one of the adjustment grooves 703, and one end of the adjustment member 704 abuts against the side baffles 501 to control the distance between the side baffles 501 and the spacer 600. An adjusting member 704 is provided between each of two adjacent spacers 600, and the two ends of the adjusting member 704 are respectively connected to the adjusting groove 703 to control the distance between the two adjacent spacers 600; the two support rods 701 located in the direction of the first side 301 form a limiting member 502 by setting the two support rods 701 above the bottom support 300.

[0043] In some implementations, such as Figure 7 As shown, the adjusting groove 703 is a U-shaped groove or a through hole, and the adjusting component 704 is a screw 706 equipped with nuts 705. The screw 706 passes through the adjusting groove 703, and then the two nuts 705 cooperate with each other, with the nuts 705 abutting against both sides of the spacer 600 (generally a plate), thereby fixing the screw 706 to the corresponding spacer 600. The distance between the two spacers 600 or between the spacer 600 and the side baffle 501 can be adjusted by adjusting the position of the nuts 705 on the screw 706.

[0044] In some implementations, such as Figure 4 As shown, the adjusting groove 703 is a U-shaped groove, and the adjusting member 704 is an insert plate 707. Several slots 708 arranged in a straight line are provided on one side of the insert plate 707. The slots 708 interlock with the adjusting groove 703, thereby connecting the adjusting member 704 to the spacer 600. Simultaneously, by using different slots 708 in conjunction with the adjusting groove 703, the distance between the two spacers 600 or between the spacer 600 and the side baffle 501 can be adjusted.

[0045] Furthermore, a buckle plate 800 is provided on the outer side of the adjusting structure 700, and both ends of the buckle plate 800 are connected to the side baffle 501 by screws. This buckle plate 800 protects the adjusting structure 700 and provides visual protection, making it more aesthetically pleasing. It also facilitates attaching information about the medicine in the corresponding slide rail 503 (such as name, barcode or QR code, other remarks, etc.) to the buckle plate 800 as needed.

[0046] Furthermore, such as Figures 1-3 As shown, a placement slot 801 can be provided on the buckle plate 800, so that the information card containing the medicine can be conveniently inserted into the placement slot 801.

[0047] It is worth noting that the adjustment structure 700 designed above has the advantage of convenient adjustment. In particular, by connecting the spacers 600 in pairs through the connectors, it is possible to adjust each spacer 600 individually. Specifically, it is possible to adjust the distance between two spacers 600 without affecting the distance between spacers 600 in other positions. Furthermore, when one of the adjustment pieces 704 is removed, the remaining spacers 600 that are interconnected through the adjustment pieces 704 can slide and adjust their positions on the support rod 701. This increases the convenience of adjusting the spacing (width) of the slide rails 503 and for installation and debugging.

[0048] It should also be noted that, for ease of understanding of the shelf arrangement for facilitating expiration date management in this application, although the above description focuses on the use of medicines for storage, this shelf arrangement for facilitating expiration date management is not limited to the use of medicines for storage. For example, if this shelf arrangement for facilitating expiration date management is set to an appropriate size and configured (placed) on a treatment cart, then this shelf arrangement for facilitating expiration date management can be used to store medicines and supplies (syringes, cotton swabs, etc.), but the method of use is still to take them from the first side and then replenish them from the second side to facilitate expiration date management.

[0049] To enhance the expandability of the shelf for managing the expiration date, each shelf 200 can be set as an independent unit and adjustable in height direction of the supporting body; or the shelf for managing the expiration date can be understood as a small unit, and then a frame for expansion can be configured. The shelf for managing the expiration date is arranged along the height direction on the frame, and several detachable mounting positions for connecting the supporting body are provided along the height direction on the frame. The spacing in the height direction can be adjusted by adjusting the mounting position of the shelf for managing the expiration date up and down on the frame.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
