Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a self-service terminal cabinet for medical drugs. Background Technology
[0002] With the continuous improvement of medical informatization and intelligence, self-service terminals are increasingly widely used in medical services. Currently, medical self-service terminals on the market mainly focus on functions such as registration, payment, and examination report inquiry, which greatly improves the service efficiency of hospitals, alleviates the pressure on manual windows, and optimizes the patient's medical experience.
[0003] However, in the drug dispensing process, the level of self-service and intelligence is still in its early stages. Traditional drug dispensing methods rely on manual allocation and verification, which has problems such as low efficiency, high labor costs, and easy errors.
[0004] In recent years, with the rise of vending machines, some medical institutions have begun to explore self-service drug dispensing systems. Among them, self-service drug dispensing terminals with a box-type structure have become the main form of implementation. These terminals usually allocate an independent storage box for each type of drug and use an information system for identification and control to achieve automatic drug dispensing. Although this box-type structure has achieved automation of drug dispensing to a certain extent, it has also exposed problems in practical applications. For example, the dispensing method is mostly gravity drop, which poses a risk of breaking fragile glass-like drugs. This not only wastes the drugs but may also bring safety hazards and cleaning difficulties. Therefore, a self-service medical drug terminal cabinet is proposed to solve the above problems. Utility Model Content
[0005] This utility model provides a self-service terminal cabinet for medical drugs, which solves the technical problems pointed out in the background.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A self-service terminal cabinet for medical drugs, comprising:
[0007] The cabinet has two uprights inside.
[0008] The circular guide rail slides are numerous and arranged vertically. They include a guide rail fixed between the inner walls of the cabinet and a rotary transmission mechanism rotatably mounted on two uprights. Multiple slides are slidably mounted on the guide rail and are all connected to the rotary transmission mechanism. Weight sensors and medicine boxes are arranged sequentially on the slides, and RFID identification tags are set on the medicine boxes.
[0009] A rotary drive mechanism, located inside the cabinet, is used to drive any one of the annular guide rail slides to rotate.
[0010] The hinged doors are located on the front of the cabinet, and their number is the same as the number of the circular guide rail slides. Each of the circular guide rail slides corresponds to a specific position. An electric door lock is installed between the opening and closing side of the hinged door and the cabinet.
[0011] The number of RFID sensors is the same as that of the circular guide rail slide, and they are respectively installed below each of the opening and closing doors on the inside of the cabinet, facing the corresponding RFID identification tag, for reading the RFID identification tag at the opening and closing door.
[0012] Based on the above technical solution, the present invention can be further improved as follows.
[0013] Furthermore, a fixing bracket is provided on the outer side of the guide rail body to be connected to the inner wall of the cabinet.
[0014] Furthermore, the upright is provided with an annular groove for rotatably mounting a rotary transmission mechanism.
[0015] Furthermore, the rotary transmission mechanism includes two rotary sprockets respectively rotatably disposed outside the annular groove, and a rotary chain is mounted on the external transmission sleeve of the two rotary sprockets. The slide is connected to the rotary chain through a connecting part provided thereon.
[0016] One of the rotating sprockets is fixed with a driven gear whose diameter is larger than that of the sprocket, and the gap between the driven gear and the rotating sprocket is greater than the height of the connecting part.
[0017] Furthermore, the rotary drive mechanism includes a vertical support plate disposed in the cabinet, the vertical support plate being located in the rotary chain, a vertically mounted linear module disposed on the vertical support plate, a drive device disposed on the linear slide of the linear module, and a transmission gear disposed on the output shaft of the drive device that can mesh with any driven gear.
[0018] Furthermore, symmetrical meshing guide slopes are provided on both the upper and lower sides of the meshing point between the driven gear and the transmission gear.
[0019] Furthermore, cameras are installed at the four corners of the top of the cabinet.
[0020] Furthermore, it also includes an interactive terminal, which is located on one side of the cabinet.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0022] 1. This self-service medical pharmacy terminal uses a medicine box that can be horizontally rotated and moved to the dispensing port, rather than the traditional gravity-drop dispensing method. This stable horizontal transfer method fundamentally avoids the risk of fragile medicines breaking or shattering due to free fall or collision during dispensing. This not only significantly reduces medicine loss and waste, but also eliminates the resulting safety hazards and cleaning difficulties, significantly improving the safety of the medicine dispensing process. It is especially suitable for medicines that are sensitive to impact.
[0023] 2. This self-service medical drug terminal cabinet, through the setting of multiple vertically arranged circular guide rail slides and their linked rotary drive mechanism, realizes multi-level and automated management of drug storage and dispensing. Compared with traditional box-type drug dispensing terminals, this structure significantly reduces the overall size of the equipment, improves space utilization, and avoids the problem of bulky equipment caused by a wide variety of drugs.
[0024] 3. This self-service medical drug terminal cabinet, through the cooperation of RFID identification tags on the sliding table and corresponding RFID sensors inside the cabinet, can accurately identify drug information, ensuring the accuracy and traceability of drug dispensing, and improving the security and intelligence level of drug management. In addition, by installing multiple cameras on the top of the cabinet, the operation process of the terminal cabinet can be monitored in all directions, further enhancing the security and controllability of the drug dispensing process.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0033] like Figure 1-5 As shown in the figure, a self-service medical drug terminal cabinet in this embodiment includes a cabinet body 1, a circular guide rail slide 3, a rotary drive mechanism 4, an RFID sensor, and an opening and closing door 5.
[0034] In this embodiment, the cabinet 1 is designed with dimensions of 1800mm high × 600mm wide × 800mm deep, which conforms to ergonomic principles, making it easy for users to operate and pharmacists to maintain. It adopts a composite structure of stainless steel frame and high-strength tempered glass. The cabinet 1 is equipped with two uprights 2 inside, which are used to support and guide the operation of the circular guide rail slide 3.
[0035] The number of annular guide rail slides 3 is multiple and arranged vertically. The specific number can be adjusted according to actual needs. Each layer can operate independently to realize multi-layer medicine storage and dispensing functions. Specifically, it includes a guide rail body 301 fixed between the inner walls of the cabinet 1 and a rotary transmission mechanism that can be rotatably set on two uprights 2. Multiple slides 303 are slidably set on the guide rail body 301 and are all connected to the rotary transmission mechanism. Weight sensors 9 and medicine boxes 10 are arranged sequentially on the slides 303 for real-time monitoring of medicine status and medicine holding. RFID identification tags 11 are set on the medicine boxes 10 for identifying the type of medicine box 10.
[0036] This design allows the slide 303 to slide on the guide rail 301 via a rotary transmission mechanism, thereby rotating the required medicine to the dispensing point. After the type of medicine box 10 is confirmed by the RFID identification tag 11, it is easy for the user to take it. At the same time, after the user takes it, the weight sensor 9 detects the weight change to determine whether the retrieval was successful. Since the medicine is carried by the medicine box 10 and can be rotated horizontally to the dispensing point, rather than the traditional gravity-drop dispensing method, this stable horizontal transfer method fundamentally avoids the risk of fragile medicines breaking or shattering due to free fall or collision during the dispensing process. This not only greatly reduces medicine loss and waste, but also eliminates the resulting safety hazards and cleaning difficulties, significantly improving the safety of the medicine dispensing process, and is especially suitable for medicines that are sensitive to impact.
[0037] The rotary drive mechanism 4 is located inside the cabinet 1 and is used to drive any one of the annular guide rail slides 3 to rotate, providing driving force for the rotation of any one of the annular guide rail slides 3.
[0038] The opening and closing doors 5 are located on the front of the cabinet 1. The number of them is the same as the number of the circular guide rail slides 3, and they correspond one by one with the position of the circular guide rail slides 3. An electric door lock is installed between the opening and closing side of the opening and closing door 5 and the cabinet 1, so that medicines on different circular guide rail slides 3 can be taken out through each opening and closing door 5. At the same time, the electric door lock can be automatically unlocked.
[0039] It should be noted that the electronic door lock uses common commercially available products and is based on existing technology, so it will not be described in detail here.
[0040] The number of RFID sensors is the same as that of the circular guide rail slide 3, and they are respectively installed below each of the opening and closing doors 5 on the inside of the cabinet 1, facing the corresponding RFID identification tag 11, for reading the RFID identification tag 11 at the opening and closing door 5.
[0041] With this design, when the slide 303 moves to the position of the opening and closing door 5, the RFID sensor can accurately read the RFID identification tag 11 on the medicine box 10 to confirm the medicine information, prevent accidental dispensing of medicine, and after confirmation, open the electric door lock of the opening and closing door 5.
[0042] In the preferred embodiment, the outer side of the guide rail 301 is provided with a fixing bracket 302 that is connected to the inner wall of the cabinet 1. The guide rail 301 is stably connected to the inner wall of the cabinet 1 through the fixing bracket 302 to ensure its stability and safety.
[0043] In addition, the upright 2 is provided with an annular groove 201 for rotatably mounting the rotary transmission mechanism, which ensures the stability of the rotation of the rotary transmission mechanism.
[0044] Furthermore, the rotary transmission mechanism includes two rotary sprockets 304 respectively rotatably disposed outside the annular groove 201. A bearing is provided at the annular groove 201 to rotatably mount the rotary sprockets 304. A rotary chain 305 is mounted on the outer transmission sleeve of the two rotary sprockets 304. The length of the rotary chain 305 is adapted to the distance between the two rotary sprockets 304 to ensure that it can maintain rotational tension. The slide 303 is connected to the rotary chain 305 through a connecting part 306 provided thereon.
[0045] With this design, the rotation of the rotating chain 305 can drive the slide 303 to rotate on the guide rail 301. The connection between the connecting part 306 and the rotating chain 305 adopts the conventional technical means of the ring guide rail slide 3, so it will not be described in detail here.
[0046] In addition, a driven gear 307 with a diameter larger than that is fixed on one of the rotating sprockets 304 to facilitate its transmission connection with the rotating drive mechanism 4. The gap between the driven gear 307 and the rotating sprocket 304 is greater than the height of the connecting part 306, thereby preventing unnecessary collisions between the connecting part 306 and the driven gear 307.
[0047] In the preferred embodiment, the rotary drive mechanism 4 includes a vertical support plate 401 disposed in the cabinet 1. The vertical support plate 401 is located in the rotary chain 305. A vertically mounted linear module 402 is disposed on the vertical support plate 401. A drive device 403 is disposed on the linear slide of the linear module 402. The drive device 403 is a transmission combination device of a motor and a reducer. A transmission gear 404 that can mesh with any driven gear 307 is disposed on the output shaft of the drive device 403.
[0048] With this design, the transmission gear 404 can mesh with any driven gear 307 through the drive of the linear module 402, thereby driving the corresponding layer's annular guide rail slide 3 to rotate and move the slide 303 to the designated opening and closing door 5 position.
[0049] Furthermore, symmetrical meshing guide slopes are provided on both the upper and lower sides of the edge meshing point between the driven gear 307 and the transmission gear 404 to ensure a smooth transition during meshing and improve transmission accuracy and stability.
[0050] In the preferred embodiment, cameras 7 are installed at the four corners of the top of the cabinet 1 to monitor the operation of the equipment during use, ensuring the safety and traceability of drug distribution.
[0051] The preferred solution also includes an interactive terminal 6, which is set on one side of the cabinet 1 as a human-computer interaction interface for carrying out the corresponding medication dispensing process. This is existing technology in the field and therefore will not be described in detail here.
[0052] In summary, the steps for patients to obtain their medication are as follows:
[0053] Identity verification and prescription retrieval: Patients can log in by swiping their medical insurance card / ID card or scanning a QR code on the interactive terminal 6. The system will automatically retrieve the electronic prescription and display the list of medications to be collected.
[0054] Initiating drug positioning and transmission: After the patient confirms the prescription, the system executes automatically. First, according to the layer number of the circular guide rail slide 3 where the drug is located, the linear module 402 raises and lowers the transmission gear 404 to the corresponding layer, meshes with the driven gear 307, and drives the target circular guide rail slide 3 to rotate. The target medicine box 10 rotates horizontally along the guide rail body 301 with the slide 303 to the designated opening and closing door 5 position.
[0055] Automatic drug information verification: When the medicine box 10 reaches the opening and closing door 5, the RFID sensor on the inside of the door reads the RFID identification tag 11 of the medicine box 10 and compares it with the prescription information. The weight sensor 9 detects whether the initial weight of the medicine matches the expectation. After successful verification, the electric door lock automatically unlocks the corresponding opening and closing door 5.
[0056] Safe medication retrieval: The medication moves horizontally and stably within the medicine box 10 throughout the entire process without falling. The medication is gently picked up manually, completely avoiding damage to fragile medications due to impact.
[0057] Medication collection completed: Weight sensor 9 performs secondary weight verification, detects changes in remaining weight, confirms that the medication has been collected, and records and provides feedback: The system updates the inventory, and the interactive terminal 6 displays "Medication collection successful".
[0058] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
