Description

Technical Field

[0001] This invention belongs to the field of medical supplies storage technology, specifically relating to an AI-driven modular SPD intelligent storage cabinet for medical supplies and its control method. Background Technology

[0002] SPD stands for Supply, Processing, and Distribution. It's a lean management model for medical consumables that optimizes management processes and improves efficiency by linking core members of the internal and external supply chain. With the development of modern healthcare systems, hospitals and medical institutions have placed higher demands on the management of pharmaceuticals and medical consumables. Traditional medical supply storage cabinets often rely on manual or semi-automatic operation, which has many shortcomings in practical use.

[0003] For example, a smart distribution cabinet for community disaster emergency supplies, with Chinese patent application number CN202411814697.6, features a modular design that allows for the addition or reduction of the number of cabinets as needed, improving the flexibility of supply distribution. The cabinet's quick docking with the main cabinet enables rapid deployment in emergencies, enhancing the speed of disaster emergency response. Information exchange between the cabinets via RFID tags and integrated cables allows for precise management of the type, quantity, and location of supplies, ensuring effective allocation and use. Simultaneously, supply information is synchronized to a cloud server for remote management and auditing, enabling rapid response to community needs, accurate distribution of required supplies, and improved efficiency in disaster emergency response.

[0004] While smart distribution lockers, as described in the aforementioned comparative documents, offer some convenience, they also have some drawbacks in practical use: Firstly, during the use of medical supplies, when a certain medicine or consumable is about to run out and needs to be replenished, staff usually need to open the storage cabinet door to put the new supplies inside. However, this operation inevitably leads to a significant loss of cold air inside the cabinet. Especially in low-temperature storage environments, frequent opening and closing of the cabinet door can significantly affect the temperature stability inside the cabinet, which may in turn affect the quality and shelf life of the medical supplies. In addition, opening the cabinet door also introduces outside air, increasing the risk of humidity fluctuations inside the cabinet and further threatening the safety of sensitive medical items.

[0005] Secondly, during routine access to medical supplies, operators need to open the cabinet door multiple times to retrieve the required items. This not only exacerbates the aforementioned temperature fluctuation problem but also easily allows external dust to enter the cabinet. Dust accumulation not only affects the reliability of equipment operation but may also contaminate medical supplies. Furthermore, frequent door opening and closing increases energy consumption, reduces the efficiency of the refrigeration system, and is detrimental to energy conservation and environmental protection requirements. Summary of the Invention

[0006] The purpose of this invention is to provide an AI-driven modular SPD intelligent storage cabinet for medical supplies and a control method, which can improve the efficiency of medical supply management, ensure the stability of the storage environment, and enhance the safety and reliability of the system.

[0007] The specific technical solution adopted by this invention is as follows: AI-driven modular SPD smart storage cabinet for medical supplies includes a control cabinet and at least one storage cabinet that can be connected to the control cabinet.

Magnetic blocks are fixedly embedded in an array at the upper end of the baffle.

[0010] In a preferred embodiment, the feed unit includes a rotating rod, which is rotatably connected to the upper end of the housing via a bearing. A motor is fixedly mounted on the sealing plate, and the output shaft of the motor is fixedly connected to the central shaft of the rotating rod. A slide rod is also fixedly connected to the upper end of the housing.

[0011] In a preferred embodiment, the abutting part includes a wire block, which is sleeved on a rotating rod. A slider is fixedly connected to the upper end of the wire block, and the slider is slidably connected to the sliding rod. Round rods are rotatably connected to both sides of the wire block. Fixed blocks are fixedly connected to the ends of the two round rods that are far apart from each other. A torsion spring is sleeved on the outer side of the round rod, and the two ends of the torsion spring are fixedly connected to the fixed blocks and the wire block, respectively. A push rod is fixedly connected between the two fixed blocks, and a top rod is fixedly connected to one side of the slider.

[0012] In a preferred embodiment, the clamping part includes a support plate, which is fixedly connected to the inner wall of the outer shell. The bottom surface of the support plate is fixedly connected with a first clamping plate arranged in an array. The support plate is also provided with sliding grooves arranged in an array. A moving block is slidably connected in the sliding groove. The lower end of the moving block is fixedly connected with a second clamping plate. A compression spring is fixedly connected between the moving block and the sliding groove.

[0013] In a preferred embodiment, the warning unit includes a contact switch, which is fixedly connected to the inner wall of the housing, and warning lights are installed at both ends of the housing.

[0014] In a preferred embodiment, the sealing part includes a first groove and a second groove, both of which are formed on the storage cabinet. A cylinder is rotatably connected to the upper end of the storage cabinet and the transfer cavity via a bearing. A sealing plate is fixedly sleeved on the cylinder, and gears are fixedly installed at both ends of the cylinder.

[0015] In a preferred embodiment, the drive unit includes vertical rods, a plurality of which are fixedly connected to a first groove. Lifting blocks are slidably connected to the plurality of vertical rods. A spring is fixedly connected to the upper end of each lifting block, and the other end of the spring is fixedly connected to the top surface of the inner cavity of the first groove. Racks are fixedly connected to both sides of each lifting block. A connecting rod is fixedly connected to the lower end of each lifting block, and the connecting rod extends into a second groove. A pedal is fixedly connected to the connecting rod. The control method for the AI-driven modular SPD intelligent storage cabinet for medical supplies, applied to the aforementioned AI-driven modular SPD intelligent storage cabinet for medical supplies, includes the following steps: Step 1: Slide the storage unit containing medical supplies into the back of the storage cabinet, with its bottom surface touching the top of the support base; Step 2: When feeding, start the feed unit to move the contact unit. The clamping part is opened by the squeezing of the contact unit, so that the medical supplies fall one by one. Step 3: When the contact part moves to the frontmost position, the alarm is triggered to remind staff to replenish medical supplies; Step 4: When retrieving the materials, first open the sealing part through the drive unit to let the medical supplies fall to the bottom of the transfer chamber, then close the sealing part, and then open the sealing door to take out the medical supplies. Step 5: When feeding is required, seal both sides of the outer casing with baffles and seal the discharge port at the bottom of the outer casing with the support base to reduce the leakage of cold air. Step Six: The control cabinet has a built-in AI module that predicts material consumption trends based on historical usage data.

[0016] The technical effects achieved by this invention are as follows: The outer shell of this invention adopts a rear-sliding installation structure, which supports independent removal for replenishment without requiring overall power outage or disruption of the sealed environment. It also incorporates a mechanism for the electromagnet and baffle to work together, as well as a sealing mechanism between the support base and the outer shell's discharge port. This ensures that a large amount of cold air is not lost from the storage cabinet during the loading process, maintaining a stable internal temperature and reducing temperature fluctuations caused by loading operations. This, in turn, guarantees the safety and stability of medical supplies during storage. This invention, through the alternating opening and closing of the sealing section and the sealing door, forms a double-barrier isolation structure, effectively preventing direct exchange between outside air and the cold air inside the storage cabinet, significantly reducing cold air leakage during the retrieval of medical supplies. This design not only reduces internal temperature fluctuations caused by frequent opening and closing of the cabinet door but also maximizes the stability of the internal environment, helping to extend the shelf life of medical supplies. Simultaneously, by reducing cold air leakage, the operating load and energy consumption of the refrigeration system are reduced, making it both environmentally friendly and energy-efficient. This invention utilizes a motor-driven rotating rod and a contact part, combined with a threaded feeding mechanism, to precisely control the quantity of items retrieved, avoiding the spillage or damage that can occur with traditional manual retrieval. The synergistic action of the push rod and torsion spring ensures automatic reset after each retrieval, improving operational reliability. Simultaneously, the warning unit, through a contact switch and warning light linkage, provides real-time reminders to replenish supplies when they are depleted, optimizing inventory management. Furthermore, the transparent observation window facilitates quick verification of the item's status, reducing unnecessary door opening operations and further mitigating the risk of cold air loss.

[0032] AI Module: Built-in AI processor predicts material consumption trends based on historical usage data, making it easier for managers to replenish stock in advance and reducing the incidence of inventory shortages.

[0033] Storage cabinet 2 is equipped with a refrigeration module. The refrigeration module adopts a product from the existing technology. When selecting a model, it should be chosen to meet the requirements of this application as much as possible, provided that the specifications and usage scenarios are suitable. Specific model specifications are not limited here and will not be elaborated further. For example, the refrigeration structure of refrigerators and refrigeration cabinets includes compressors, condensers, evaporators, and expansion valves.

[0034] The front of the storage cabinet 2 is equipped with a cabinet door and a lock. The cabinet door also has a transparent observation window to observe the internal condition of the storage cabinet 2.

[0035] Both storage cabinet 2 and control cabinet 1 have connecting lugs on their backs, which can be fixed together with bolts between the connecting lugs on adjacent cabinets, facilitating the splicing of multiple storage cabinets 2 and control cabinet 1.

[0036] Secondly, please refer to it again. Figure 2 and Figure 8 A junction box 11 is installed on the back of the control cabinet 1, and a composite cable 21 is connected to the lower end of the storage cabinet 2. In addition, electromagnets 31 are installed at the lower end of the support base 3 and on the top surface of the inner cavity of the storage cabinet 2.

[0037] In this embodiment, a cable reel is provided at the bottom of the inner cavity of the storage cabinet 2, and the integrated cable 21 is wound on the cable reel; the integrated cable 21 includes power wires and data wires, and has an external shielding layer (e.g., Figure 15 (As shown); the integrated cable 21 is connected to the junction box 11 to realize power supply and data transmission.

[0038] Secondly, please refer to the following as well. Figures 8 to 11 The housing assembly 41 includes an outer shell 411, which is slidably inserted into the storage cabinet 2 from the rear end and slidably connected to the support base 3. A sealing plate 412 is fixedly connected to the rear end of the outer shell 411. Mounting grooves 413 are provided on both the front and rear sides of the outer shell 411, and through holes are provided in an array at the lower end of the mounting grooves 413. A baffle 414 is slidably connected in the mounting grooves 413. A guide rod 415 and a tension spring 416 are fixedly connected to the lower end of the baffle 414. The guide rod 415 is slidably connected in the through hole at the lower end of the mounting groove 413, and the tension spring 416 is fixedly connected to the bottom surface of the inner cavity of the through hole. Magnetic blocks 417 are fixedly embedded in an array at the upper end of the baffle 414. An electromagnet 31 cooperates with the magnetic blocks 417 on the baffle 414 to control the lifting and lowering of the baffle 414 to seal both sides of the outer shell 411.

[0039] In this embodiment, the outer casing 411 slides into and is inserted from the rear side of the storage cabinet 2, with its bottom surface tightly fitted against the top surface of the support base 3 (limiting protrusions are provided on both sides of the top surface of the support base 3 to limit and guide the outer casing 411, such as...). Figure 8(As shown). After the outer casing 411 is fully inserted into the storage cabinet 2, its lower discharge port is aligned with the inclined surface on the support base 3 (see...). Figure 9 The baffle 414 can move vertically within the mounting groove 413 on the side of the housing 411. When the baffle 414 moves upward, it will stretch the tension spring 416. During the sliding process of the baffle 414, the guide rod 415 fixed to it slides within the through hole of the housing 411. The guide rod 415 and the through hole work together to achieve the guiding function and ensure the stability of the baffle 414 during the lifting process.

[0040] In addition, a sealing ring is fixedly fitted at the connection between the sealing plate 412 and the right side of the outer casing 411, and a matching sealing groove is provided on the rear side of the storage cabinet 2. After the outer casing 411 is fully embedded in the storage cabinet 2, the sealing ring is embedded in the sealing groove. The cooperation between the sealing ring and the sealing groove seals the opening on the back of the storage cabinet 2, effectively preventing the cold air inside the storage cabinet 2 from leaking out, while also preventing the intrusion of external dust.

[0041] It should be noted that a transparent observation window is provided at the front end of the outer casing 411 to observe the internal condition of the outer casing 411.

[0042] The bottom surface of the inner cavity of the outer shell 411 is connected to rotating rollers in an array.

[0043] Secondly, please refer to it again. Figure 10 The feed section 42 includes a rotating rod 421, which is rotatably connected to the upper end of the housing 411 via a bearing. A motor 422 is fixedly mounted on the sealing plate 412, and the output shaft of the motor 422 is fixedly connected to the central shaft of the rotating rod 421. A slide rod 423 is also fixedly connected to the upper end of the housing 411.

[0044] Please refer to it again. Figure 12 The contact part 43 includes a wire block 431, which is sleeved on the rotating rod 421. A slider 432 is fixedly connected to the upper end of the wire block 431, and the slider 432 is slidably connected to the sliding rod 423. Round rods 433 are rotatably connected to both sides of the wire block 431. Fixed blocks 434 are fixedly connected to the ends of the two round rods 433 that are far apart from each other. Torsion springs 435 are sleeved on the outer side of the round rods 433, and the two ends of the torsion springs 435 are fixedly connected to the fixed blocks 434 and the wire block 431 respectively. A push rod 436 is fixedly connected between the two fixed blocks 434. A top rod 437 is fixedly connected to one side of the slider 432.

[0045] In this embodiment, the medical supplies are fixed to the clamping part 44. When it is necessary to remove the medical supplies from a certain storage mechanism 4, the motor 422 is started, and the motor 422 drives the rotating rod 421 to rotate. The outer side of the rotating rod 421 is provided with a thread that matches the thread block 431, and the rotating rod 421 and the thread block 431 are connected by the thread. Therefore, when the rotating rod 421 rotates, it can push the abutment part 43 to move.

[0046] Please refer to it again. Figure 13 and Figure 14 The clamping part 44 includes a support plate 441, which is fixedly connected to the inner wall of the outer shell 411. The bottom surface of the support plate 441 is fixedly connected with a first clamping plate 442 arranged in an array. The support plate 441 is also provided with an array of sliding grooves 443. A moving block 444 is slidably connected in the sliding groove 443. The lower end of the moving block 444 is fixedly connected with a second clamping plate 445. A compression spring 446 is fixedly connected between the moving block 444 and the sliding groove 443.

[0047] In this embodiment, when the wire block 431 moves, the structure connected to it also moves synchronously. After the push rod 436 reaches the position of the moving block 444, it pushes the moving block 444 and compresses the compression spring 446. The movement of the moving block 444 causes the second clamping plate 445 to move away from the first clamping plate 442, causing the medical supplies fixed on the two clamping plates to fall onto the inclined surface of the inner cavity of the outer shell 411. These supplies then slide down the inclined surface, fall from the discharge port at the lower end of the outer shell 411 onto the support base 3, and continue to slide down the inclined surface of the support base 3, finally stopping on the sealing part 61 at the front end of the storage cabinet 2.

[0048] As the moving block 444 continues to move, when the connected compression spring 446 is compressed to its limit, the push rod 436 will be unable to push the moving block 444 further. At this point, the push rod 436 will rotate around the central axis of the round rod 433 and twist the torsion spring 435. As the push rod 436 continues to rotate, the connection between the push rod 436 and the moving block 444 will gradually disengage. As the push rod 436 continues to rotate, it will eventually move to the other side of the moving block 444, completing the removal of one medical supply. By controlling the stroke of the motor 422 to drive the contact part 43, different quantities of medical supplies can be removed. For example, moving from the initial position of the contact part 43 to the opposite side of the moving block 444 is one stroke unit. If several medical supplies need to be removed, the motor 422 is started to move the contact part 43 by the corresponding number of stroke units. This precise control ensures the efficiency and accuracy of the entire removal process.

[0049] When the medical supplies in storage unit 4 are depleted and need to be replenished, staff should operate from the rear of storage cabinet 2, pulling the handle on sealing plate 412 to extend a portion of outer casing 411 outward (see...). Figure 7 Next, the staff needs to pull up the baffle 414 and then place the medical supplies into the outer casing 411 through the side opening, ensuring that they are secured between the first clamp 442 and the second clamp 445. After completing the above steps, the outer casing 411 is reinserted into the storage cabinet 2.

[0050] It should be noted that after the outer casing 411 is fully embedded in the storage cabinet 2, the electromagnets 31 on the top surface of the storage cabinet 2 and the bottom surface of the support base 3 should be energized. The electromagnets 31 attract the magnetic block 417, causing the baffle 414 to move upward, thereby forming an opening on the side of the outer casing 411. In this way, the cold air inside the storage cabinet 2 can enter the interior of the outer casing 411 through the opening. When performing a loading operation on a specific storage mechanism 4, the power supply to the corresponding electromagnet 31 should be cut off. After the magnetic block 417 loses the attraction of the electromagnet 31, it will reset the baffle 414 under the restoring force of the tension spring 416, thereby achieving a seal on both sides of the outer casing 411. As the outer casing 411 is partially pulled out, the discharge port at the lower end of the outer casing 411 will be closed by the top surface of the support base 3. At this time, the entry of cold air will be restricted, or only a very small amount of cold air can enter the interior of the outer casing 411. Therefore, during the process of the outer shell 411 being pulled out for loading, the cold air inside the storage cabinet 2 will not be lost in large quantities, ensuring the temperature inside the storage cabinet 2 is stable, reducing temperature fluctuations caused by the loading operation, and ensuring the safety and stability of medical supplies during storage.

[0051] Please refer to it again. Figure 10 The warning unit 45 includes a contact switch 451, which is fixedly connected to the inner wall of the housing 411. Warning lights 452 are installed at both ends of the housing 411.

[0052] In this embodiment, when the contact part 43 moves to its foremost position, the top rod 437 above it applies pressure, pressing the contact switch 451. Immediately afterwards, as the contact switch 451 is activated, the warning light 452 illuminates to alert the operator.

[0053] It should be noted that the contact switch 451 is a product that is already publicly available on the market. When selecting a model, it is advisable to choose one that meets the requirements of this application, provided that the specifications and usage scenarios are suitable. Specific model specifications are not limited here.

Both the first groove 611 and the second groove 612 are opened on the storage cabinet 2. A cylinder 613 is rotatably connected to the upper end of the storage cabinet 2 and the transfer cavity 5 via a bearing. A sealing plate 614 is fixedly sleeved on the cylinder 613. Gears 615 are fixedly installed at both ends of the cylinder 613.

A spring 623 is fixedly connected to the upper end of the lifting block 622, and the other end of the spring 623 is fixedly connected to the top surface of the inner cavity of the first groove 611. A rack 624 is fixedly connected to both sides of the lifting block 622. A connecting rod 625 is fixedly connected to the lower end of the lifting block 622, and the connecting rod 625 extends into the second groove 612. A pedal 626 is fixedly connected to the connecting rod 625.

[0056] In this embodiment, after the medical supplies are removed from above and fall onto the sealing part 61, the pedal 626 is pressed down to move it downwards. The downward movement of the pedal 626 drives the lifting block 622 to move vertically downwards along the vertical rod 621 via the connecting rod 625, while simultaneously stretching the spring 623. The racks 624 on both sides of the lifting block 622 mesh with the gears 615 to achieve transmission. Therefore, during the descent of the lifting block 622, the gears 615 are driven to rotate, which in turn causes the two cylinders 613 to rotate relative to each other. The rotation of the cylinders 613 causes the sealing plate 614 to rotate, and the sealing plate 614 then comes into contact with the inner wall of the transfer cavity 5. At this time, the medical supplies can fall between the two sealing plates 614. When the medical supplies fall to the bottom of the transfer cavity 5, the pedal 626 is stopped. After the pedal 626 loses external force, the restoring force of the spring 623 will drive the lifting block 622, racks 624, connecting rod 625, and pedal 626 back to their initial positions. During the reset process, rack 624 drives gear 615, cylinder 613, and sealing plate 614 to rotate, thereby resetting the two sealing plates 614 and resealing the upper end of transfer cavity 5. After completing the above steps, the sealing door 7 can be opened to remove the medical supplies from the lower end of transfer cavity 5.

[0057] It should be noted that, in the embodiments of the present invention, the storage cabinet 2 forms a double-barrier isolation structure by setting an alternately opening and closing sealing part 61 and a sealing door 7. Specifically, when the sealing part 61 is opened to retrieve supplies, the sealing door 7 is ensured to be closed; conversely, when the sealing door 7 is opened, the sealing part 61 is ensured to be closed. Through this method, the two sealing interfaces form a pressure buffer zone, blocking the direct convection channel between the inside and outside of the cabinet, effectively preventing the direct exchange of outside air with the cold air inside the storage cabinet 2, thereby significantly reducing the leakage of cold air inside the storage cabinet 2 when retrieving medical supplies. This design, while ensuring storage and retrieval efficiency, reduces the temperature fluctuation inside the storage cabinet 2, minimizing temperature fluctuations and cold air loss caused by air exchange.

[0058] Reduced energy consumption: By reducing cold air leakage, storage cabinet 2 can more effectively maintain the set low temperature environment, thereby reducing the operating load and energy consumption of the refrigeration system.

[0059] Extending the shelf life of supplies: Reduced cold air leakage helps maintain a constant low temperature environment inside storage cabinet 2, thereby extending the shelf life of medical supplies and ensuring their quality.

[0060] The control method for the AI-driven modular SPD intelligent storage cabinet for medical supplies, applied to the aforementioned AI-driven modular SPD intelligent storage cabinet for medical supplies, includes the following steps: Step 1: Slide the storage unit 4 containing medical supplies into the back of the storage cabinet 2, with its bottom surface touching the top of the support base 3; Step 2: When feeding, start the feed unit 42 to drive the contact part 43 to move. The clamping part 44 is opened by the squeezing of the contact part 43, so that the medical supplies fall one by one. Step 3: When the contact part 43 moves to the frontmost position, the alarm part 45 is triggered to remind staff to replenish medical supplies; Step 4: When retrieving the materials, first open the sealing part 61 through the drive part 62 to let the medical supplies fall to the bottom of the transfer chamber 5, then close the sealing part 61, and then open the sealing door 7 to take out the medical supplies. Step 5: When feeding is required, the two sides of the outer shell 411 are sealed by the baffle 414, and the discharge port at the lower end of the outer shell 411 is sealed by the support 3 to reduce the leakage of cold air. Step Six: Control Cabinet 1 has a built-in AI module that predicts material consumption trends based on historical usage data.

[0061] The working principle of this invention is as follows: Medical supplies are fixed on the storage mechanism 4. When supplies need to be retrieved, the feeding unit 42 is activated to drive the contact part 43 to move. The contact part 43 squeezes and opens the clamping part 44, causing the supplies to fall one by one. An alarm part 45 is triggered to remind the user to replenish supplies. During retrieval, the driving unit 62 opens the sealing part 61 to allow the supplies to fall into the transfer chamber 5. Then, the sealing part 61 is closed and the sealing door 7 is opened to retrieve the supplies. During loading, the baffle 414 and support base 3 are used to seal the outer shell 411 to reduce cold air leakage and ensure stable temperature inside the cabinet. This design not only improves storage and retrieval efficiency but also reduces energy consumption by minimizing cold air leakage and extends the shelf life of medical supplies.

[0062] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
