Technical Field
[0001] This utility model provides a medical consumables inventory management rack based on RFID technology, belonging to the field of medical consumables management technology. Background Technology
[0002] With the rapid development of medical technology, the types and quantities of consumables used by medical institutions have increased dramatically. Currently, hospitals typically use traditional open shelves or ordinary storage cabinets to store medical consumables. This storage method has many drawbacks: First, when consumables of two specifications from the same batch need to be stored (the two specifications cannot be distinguished at a glance from their outer packaging), for example, for test strip storage tubes from the same batch, the outer packaging is basically the same, but the test strips inside are used for two different work scenarios; staff must check the product information one by one and manually classify them, which is time-consuming, labor-intensive, and prone to errors. Radio Frequency Identification (RFID) technology is a type of automatic identification technology that uses radio frequency for non-contact two-way data communication, reading and writing recording media (electronic tags) to achieve the purpose of identifying targets and exchanging data. Existing medical consumables packaging usually also has such RFID-identifiable electronic tags, which can be quickly obtained and identified by direct scanning. However, since manual classification and storage of consumables are still required after identification, it is not much faster than manual identification.
[0003] Secondly, due to the lack of an effective management system, medical staff often take consumables randomly, which is highly unpredictable and makes it difficult to follow the "first-in, first-out" principle (i.e., in inventory management, materials that enter the warehouse first should be used first, and materials that enter later should be used later, thereby ensuring that inventory materials are consumed in the order of their entry time and reducing the risk of consumables expiring due to prolonged unused use). To address these issues, there is an urgent need to develop a new type of medical consumable inventory management rack. Utility Model Content
[0004] The technical problem this invention aims to solve is that it is inconvenient to quickly identify and store consumables of different specifications in the warehouse, and it is also difficult for medical staff to follow the "first-in, first-out" principle when retrieving supplies.

The fixed cylinder, located on one side of the storage cylinder, is fixed to the ground. The fixed cylinder has a lifting component that can drive the tray to slide, and the lifting component is connected to the controller circuit.
[0008] Preferably, the RFID identification component includes an L-shaped bracket and an identification device; the bracket is fixedly connected to the support platform, the identification device is located inside the bracket, and the identification head of the identification device corresponds to the position of the feed hole.
[0009] Preferably, the transfer hole on the rotating plate is a through hole, and the depth of the transfer hole for placing medical consumables is greater than the height of the medical consumables.
[0010] Preferably, the rotating assembly includes a rotating motor and a rotating shaft; the rotating motor is disposed at the bottom of the support platform, the rotating shaft is fixedly connected to the output shaft of the rotating motor, and the rotating shaft is fixedly connected to the rotating plate.

[0023] The present invention will be further described below with reference to the accompanying drawings.
[0024] This utility model provides a medical consumables inventory management rack based on RFID technology: it includes two storage cylinders 1, and each of the two storage cylinders 1 contains medical consumables 20 of the same shape but different types. The medical consumables 20 are equipped with electronic tags that can be identified by RFID identification devices 4, and the electronic tags are located at the top of the cylindrical medical consumables 20.
[0025] like Figure 5 As shown, the upper end of the storage cylinder 1 has an opening structure for easy feeding. The medical consumables 20 are stacked inside the storage cylinder 1, and the side wall of the storage cylinder 1 has a discharge hole 8 near the bottom of the storage cylinder 1. The structure of the storage cylinder 1, combined with the stacked state of the medical consumables 20, can ensure that the medical consumables 20 enter from the upper end and exit from the lower end, thus facilitating the implementation of the "first-in, first-out" principle.
[0026] like Figure 1 , 3 As shown, the support platform 6 is fixedly installed above the two storage cylinders 1. The support platform 6 has a groove 9, and a rotating plate 10 is rotatably installed in the groove 9 through a rotating assembly. The rotating assembly includes a rotating motor 13 and a rotating shaft 12. The rotating motor 13 is installed at the bottom of the support platform 6, and the rotating shaft 12 is fixedly connected to the output shaft of the rotating motor 13, and the rotating shaft 12 is fixedly connected to the rotating plate 10.
[0027] like Figure 1 , 3 As shown in Figure 5, the upper surface of the support platform 6 has a feeding hole 5 for feeding medical consumables 20, and the feeding hole 5 is connected to the groove 9; the lower surface of the support platform 6 has two symmetrical discharge holes 21 connected to the groove 9, and the two discharge holes 21 are respectively corresponding to the upper ends of the two storage cylinders 1; the rotating plate 10 has a transfer hole 11 corresponding to the feeding hole 5, which can ensure that the medical consumables 20 entering from the feeding hole 5 can fall directly into the transfer hole 11, and the two discharge holes 21 are both located on the rotation path of the transfer hole 11. On the support plate 6, there is an RFID identification component corresponding to the feed hole 5. According to the identification result of the RFID identification component, it is only necessary to control the rotation direction of the rotating plate 10 so that the transfer hole 11 corresponds to the two discharge holes 21 respectively to complete the corresponding storage. The transfer hole 11 is a through hole on the rotating plate 10, and the depth of the transfer hole 11 that can hold the medical consumable 20 is greater than the height of the medical consumable 20, so as to avoid the medical consumable 20 from protruding from the transfer hole 11 and affecting the transfer when the rotating plate 10 rotates.
[0028] like Figure 1As shown, the RFID identification component includes an L-shaped bracket 3 and an identification device 4. The bracket 3 is fixedly connected to the support platform 6, and the identification device 4 is located inside the bracket 3. The identification head of the identification device 4 corresponds to the position of the feed hole 5, enabling it to identify the electronic tag on the medical consumable 20 located in the transfer hole 11 below the feed hole 5. A controller 2 is provided on the support platform 6, which is electrically connected to the identification device 4, and the controller 2 is also electrically connected to the rotation motor 13.
[0029] like Figure 4 As shown, a tray 19 is slidably mounted inside the storage cylinder 1, and medical consumables 20 are stacked on the tray 19. A fixed cylinder 7, located on one side of the storage cylinder 1, is fixed to the ground. The fixed cylinder 7 contains a lifting assembly that can drive the tray to slide, and the lifting assembly is electrically connected to the controller 2. The lifting assembly can move the stacked medical consumables 20 up and down, providing space for newly received medical consumables 20 and facilitating their retrieval. The lifting assembly includes an adjusting motor 14, a lead screw 15, and a slider 16. The adjusting motor 14 is mounted on the fixed cylinder 7. The lead screw 15, which is rotatably mounted inside the fixed cylinder 7, is fixedly connected to the output shaft of the adjusting motor 14. The slider 16 is threadedly connected to the lead screw 15. The side walls of the fixed cylinder 7 and the storage cylinder 1 are provided with corresponding guide grooves 17. A connecting rod 18 is fixedly connected to the slider 16, and the connecting rod 18 passes through the guide groove 17 and is fixedly connected to the support plate 19. The controller 2 is electrically connected to the adjusting motor 14, so that the adjusting motor 14 can be started according to the storage status.
[0030] The principle of this utility model
[0031] like Figure 1 , 3 As shown, when using this application to store medical consumables 20, the medical consumables 20 are first placed into the transfer hole 11 of the rotating plate 10 through the feed hole 5. The identification device 4 identifies the medical consumables 20 and transmits the identification result to the controller 2. The controller 2 determines the type of the medical consumables 20 based on the identification result and accordingly starts the adjusting motor 14 on the fixed cylinder 7 corresponding to the storage cylinder 1. Figure 4 As shown, the slider 16 lowers the slide and the medical consumables 20 on it by the height of one medical consumable 20, making room for the medical consumables 20 to be stored. Then, the controller 2 controls the rotating motor 13 to rotate, which in turn rotates the rotating plate 10, causing the transfer hole 11 to rotate the medical consumables 20 to the position of the storage cylinder 1, and the transfer hole 11 to correspond to the feeding hole 21. At this time, the medical consumables 20 located in the transfer hole 11 can enter the storage cylinder 1 through the feeding hole 21, completing the identification and classification of the medical consumables 20. Finally, the rotating motor 13 is started to reset the rotating plate 10, and the operation can be repeated. The whole process does not require manual operation, is simple and convenient, and greatly improves the efficiency of classification and feeding.
[0032] When using this application to retrieve medical consumable 20, if Figure 4 As shown, the operator controls the adjustment motor 14 to start, causing the tray 19 to slide the stacked medical consumables 20 downwards until the tray 19 is at the bottom of the storage cylinder 1. At this time, the bottom medical consumable 20 corresponds to the discharge hole 8. The operator can then directly remove the bottom medical consumable 20, ensuring the "first-in, first-out" principle.
[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
