Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to drug dispensing carts. Background Technology

[0002] Current hospital drug dispensing mainly includes: automated outpatient dispensing, manual inpatient dispensing, and PIVAS (Pharmacy Intensive Care System). In grassroots hospitals with insufficient resources and scale, inpatient medications mainly rely on manual dispensing by the central pharmacy, which often results in medication errors (type, quantity, specifications) and omissions. This increases the pressure on nurses to perform the "three checks and seven verifications" (checking, verifying, and verifying). In today's increasingly complex patient population and the severe medical environment of multiple disciplines and multiple diseases, both pharmacists and nurses face higher requirements for drug dispensing and use. Therefore, information-based, fully traceable dispensing is particularly important, and a multi-functional dispensing cart that meets these requirements is especially crucial. Utility Model Content

[0053] For ease of description and understanding, the proximal end in this article generally refers to the side closest to the operator (e.g., a doctor), while the distal end is the side relatively far away. Along the intervention path, each component has its own relative distal and proximal ends. The straight line between the proximal and distal ends of each component determines the axial direction, and correspondingly also determines the radial direction perpendicular to the axial direction and the circumferential direction around the axial direction.

[0054] See Figures 1-7 This application provides a medicine handling cart, hereinafter referred to as cart 1000 for ease of description. The cart 1000 is used to transfer medicines in the medicine shelf storage area 700, and to verify and confirm the type, quantity, weight and other information of the medicines during the transfer process, as well as to monitor and record the operator's taking, transferring and placing of medicines, so as to facilitate traceability when needed.

[0055] The cart 1000 includes a frame 100, a weighing platform 200, a collection component, and a mobile medicine box 400. The frame 100 includes a first body 110 and a second body 120. The bottom of the first body 110 and the second body 120 are equipped with wheels 150. The second body 120 slides relative to the first body 110 and has a folded state close to the first body 110 and an extended state away from the first body 110. The sliding direction of the second body 120 is along the length of the frame 100, and opposite to the width. The mobile medicine box 400 rests on the frame 100 for storing medicines. Both the first body 110 and the second body 120 have spaces for placing the mobile medicine box 400. These spaces can also hold other items. The frame 100 can switch between the folded and extended states according to the actual items it needs to carry, making it easy to push. Alternatively, when not in use and empty, the frame 100 can be switched to the folded state to reduce its footprint.

[0056] A weighing platform 200 is installed on the first vehicle body 110 to measure the medicines from the medicine shelf storage area, specifically obtaining the weight information of the corresponding medicines. A data acquisition component is installed on the first vehicle body 110 to acquire image information from the medicine shelf storage area and the weighing platform. This image information includes at least the entire process of the medicines moving from the medicine shelf storage area to the mobile medicine box 400, as well as the quantity and type of the medicines. This image information is stored locally and on a cloud server and can be used for later traceability, etc. The trolley 1000 also includes a control cabinet 600 installed on the first vehicle body 110. After the image information is transmitted to the control cabinet 600, the control cabinet 600 has at least the ability to upload the image information and process it locally. The processing includes recognizing the image information to determine the type of medicine, etc. The entire process of medicine movement and the recognition method during this process are described in the following embodiments.

[0057] This application provides a method for dispensing medicines in a ward pharmacy, including:

[0058] S01, assign drug codes; S02, after assigning drug codes, put the drug on the shelf;

[0059] S100, retrieving medication from the shelf includes:

[0060] S110: Obtain the medicine list, scan the code to pick up the corresponding medicine; the entire process of picking up medicine from the medicine shelf is monitored by video by the data acquisition component.

[0061] The "code" assigned to the drug in S01 is in the form of a QR code. The "code" is placed on the label holder at the front of the drug shelf storage area; the "code" can be generated by extracting relevant information such as the generic name / trade name of the drug. It is divided into whole boxes (e.g., 5, 10, 20, 30, etc.) or multiple QR codes / barcodes corresponding to individual quantities of 1-50 doses, depending on the quantity and packaging of the drug. The QR code can be used to input relevant drug information, such as dosage, usage, contraindications, indications, and expiration date.

[0062] Drug traceability codes are extracted to generate codes for drug coding: the total traceability code on the outer packaging of drugs entering the hospital pharmacy is used as the basis for the code, and a dynamic code is set on the drug shelf. The code is dynamically updated according to the drug traceability code imported from the drug entry information. The dynamic drug traceability code is displayed on a small LCD screen set on the label holder of the drug shelf.

[0063] As needed, RIFD electronic tags can be added to each type of medicine to bind more information about the medicine and to locate it for automatic navigation later. The data collection component can recognize any type of "code".

[0064] In S02, medicines are classified and categorized by type and nature and placed in cabinets. Whole and small packages are arranged in an orderly manner from left to right according to the principle of first-come, first-served. Their QR codes / traceability codes are placed in the label holders in front of the medicine shelves. At the same time, electronic tags and indicator lights for each medicine are inserted into them. The indicator lights are powered by an external power source and can maintain red and green color differentiation or flashing mode to provide prompts when retrieving medicines. The electronic tags are used to match the reader on the automatic moving adjustment lever to locate and scan the target medicine.

[0065] In S110, a medication list is retrieved. A tablet / touchscreen LCD displays this list, located on the top left of the multi-functional dispensing cart. The HIS (Hospital Information System) confirms medication orders from a specific department through the ward pharmacy system. The summary is then generated via a data protocol call, displaying a temporary dispensing list on the tablet / touchscreen LCD. When dispensing begins, medications are arranged according to the temporary dispensing list, from top to bottom. Each medication entry's indicator light flashes / turns red. After each medication is dispensed, its information entry turns gray. The HIS system is linked to the data acquisition component; for example, after medication verification is successful and it is placed in the mobile medicine box, a completion message is transmitted to the HIS system.

[0066] When scanning to retrieve medication, the identification device is located on the frame 100. Its height is automatically / manually adjusted according to the position of the medication, with indicator lights on the medication providing further guidance. The identification device automatically / manually focuses on reading and binding the code on the medication rack. The appropriate quantity of medication can be retrieved according to various different modes. Three implementation examples are provided below:

[0067] First embodiment (scanning the code to confirm the quantity of medicine):

[0068] The medication dispensing process is based on the quantity displayed on the tablet / touchscreen LCD device. The medication's QR code is scanned using a recognition device. For example, 13 doses of medication can be dispensed by scanning the QR codes for 10 doses and 3 doses twice, or by scanning the QR codes for 13 doses once, or by scanning the QR codes for 10 doses and 1 dose three times. After receiving the medication, it is placed in a multi-functional transport medicine box under camera monitoring. The medication information turns gray, and the next medication is then scanned and dispensed.

[0069] In the second embodiment (using QR codes to verify the quantity of drugs):

[0070] The medication dispensing process involves scanning the QR code on the medication based on the quantity displayed on the tablet / touchscreen LCD device. For example, dispensing 13 doses of medication involves confirming the medication via the QR code. The weighing device offers multiple conversion modes: 5 doses per box * 2 + 3 doses per loose box; 5 doses per box + 8 doses per loose box; 13 doses per loose box. The dispensing staff can randomly take the corresponding quantity and place the medication on the weighing platform. If the weight is overweight or underweight, the screen will automatically alert the staff and require intervention to confirm. Once the weight and quantity are correctly converted, the medication is placed in the multi-functional transport medicine box under camera monitoring, and the medication information turns gray, allowing the next medication to be scanned and dispensed.

[0071] In the third embodiment (verifying the quantity of medicines using a combination of QR codes and AI visual recognition):

[0072] The medication dispensing process involves scanning the QR code of the medication based on the quantity displayed on the tablet / touchscreen display device. For example, if 13 doses of medication are dispensed, the medication is confirmed by scanning the QR code. After taking the medication, it is placed on the operating platform, where it is counted and identified by an AI visual recognition camera. Once the quantity is correct, the medication is placed in a multi-functional transport medicine box under the monitoring of the AI ​​visual recognition camera, and the medication information turns gray, allowing the next medication to be scanned and dispensed.

[0073] The pharmacy's drug dispensing method also includes S200: Drug Verification. Specifically, the control cabinet and / or cloud server identify and count image information, matching the quantity dispensed in the ward's drug dispensing and return summary table. If the count matches, it's correct; otherwise, it's incorrect, and a warning is issued. During the weighing and calculation process, the weighing platform is located on top of the cart. The platform has an independent database, maintaining and storing each drug in the database based on its packaged and individual weights. It also has multiple measurement mode code instructions. Drugs are placed on the weighing platform, which provides various conversion modes, such as: 13 units: 5 units (boxed weight * 2) + 3 individual units; 5 units (boxed weight) + 8 individual units; 13 individual units. Dispensing personnel can randomly select the corresponding quantity and place it on the weighing platform. The platform automatically calculates the weight; if it's overweight or underweight, the screen automatically warns, requiring the dispensing personnel to intervene and confirm. If the weight and quantity conversion match, it's correct.

[0074] Alternatively, the weighing platform 200 may only acquire the weight of the medicine and transmit the weight information to the control cabinet 600, which will then perform calculations based on the image information. The calculation method is the same as the aforementioned weighing platform calculation mode.

[0075] Regarding the specific structure of the frame 100:

[0076] In one embodiment, a lifting device 130, such as a lead screw guide, is provided on the first vehicle body 110. The acquisition components include a first camera 310 and a second camera 320. The first camera 310 is one of the aforementioned identification devices. It focuses on the medicine shelf storage area and is used to acquire and identify real-time images (a type of image information) of medicines being removed from the medicine shelf storage area. At the same time, the image information is transmitted to the control cabinet 600, and the control cabinet, in conjunction with the cloud server, identifies and judges the "code" in the image information.

[0077] The second camera 320 faces the weighing platform 200 in a horizontal position and is used to capture real-time images (a type of image information) of the weighing platform 200 during measurement. The recorded image information is transmitted to the control cabinet 600, where it counts the medications and matches them with the medication quantity in the ward medication return summary table. If the count is correct, it is correct; otherwise, it is incorrect, and a warning is issued. The warning method includes displaying a prompt on a tablet computer / touchscreen LCD or using a buzzer on the vehicle frame 100 to emit a beeping sound when a warning is issued. The first camera 310 and the second camera 320 may be, for example, dome cameras with AI recognition capabilities. For example, the first camera 310 automatically tracks and focuses on a person's hand, and the second camera 320 automatically tracks and focuses on the medications. Preferably, the coverage area of ​​the second camera 320 includes both the weighing platform 200 and the mobile medicine box 400, meaning it can monitor the movement of medications from the weighing platform 200 to the mobile medicine box 400.

[0078] The data acquisition component enables video monitoring. During the scanning and retrieval of target medicines in different medicine cabinet layers, the camera records and monitors the entire process. It uses cloud service storage space, and the storage time can be set according to needs and storage requirements. It supports loop overwrite and playback functions.

[0079] The data collection component also includes a barcode scanner 210 mounted on the first vehicle body. The barcode scanner 210, such as the aforementioned tablet computer, is used to open the mobile medicine box 400. The mobile medicine box 400 has a display screen that dynamically generates a QR code for the barcode scanner 210 to scan. After the scan is confirmed, the mobile medicine box 400 opens.

[0080] like Figure 7 and Figure 12As shown, a platform 111 is provided on the top layer of the first vehicle body 110, and a weighing platform 200 and a barcode scanner 210 are detachably mounted on the platform 111. The weighing platform 200 can be removed for maintenance, charging, etc. The barcode scanner 210 can be detached and held by hand for easy operation.

[0081] like Figure 7 , Figure 13 and Figure 14 As shown, the trolley 1000 also includes a robotic arm 140 mounted on the first vehicle body 110. The robotic arm 140 includes multiple links and joints connecting adjacent links. The barcode scanning device 210 is magnetically connected to the end link. The movement of the robotic arm allows the barcode scanning device 210 to have an inclined posture that detaches from and moves away from the platform 111, and a storage posture that retracts into the platform 111. The barcode scanning device 210 in such a way... Figure 13 and Figure 14 Even in the tilted position shown, operation is still convenient. The magnetic attachment makes it easy for the operator to pick up or put back the device. If the device is not placed correctly and the robotic arm 140 returns to its original position, causing a mismatch between the scanning device 210 and the platform 111, the platform 111 will lift the scanning device 210 out of the robotic arm 140. The operator can then easily reposition the scanning device 210 into the platform 111. The robotic arm 140 is electrically connected to the control cabinet 600, and corresponding buttons on the platform 111 control the robotic arm 140 via the control cabinet 600.

[0082] In the diagram, the upper part of the first vehicle body 110 is divided into two areas. The first area is equipped with a platform 111, and the second area is equipped with an operating table 112 for placing temporary items.

[0083] See again Figures 1-6 The first vehicle body 110 and the second vehicle body 120 are frame structures. The first vehicle body 110, as shown in the diagram, includes four first uprights 113 arranged at the four corners, and first crossbars 114 connecting adjacent first uprights 113. The lengths of the first uprights 113 are not necessarily the same. The first vehicle body 110 has three layers, each layer including four first crossbars 114 at the same height. The bottom and second layers also include first support plates 115. The control cabinet 600 is installed on the second layer and located below the first area. A trash can (not shown in the diagram) is located on the second layer and below the second area. The bottom layer can be used to place portable medicine boxes or other items.

[0084] The first crossbar 114 of the first vehicle body 110 is a hollow tube. The second vehicle body 120 includes two parallel second columns 121 and a second crossbar 122 connecting the two second columns 121. Along the length direction, each of the two second columns 121 is provided with a connecting rod 123 that slides and nests with the corresponding first crossbar 114. The second vehicle body 120 has two layers. The second layer is used to place the mobile medicine box 400, which allows the mobile medicine box 400 to be opened without interference.

[0085] Each layer of the second vehicle body 120 is detachably provided with a second support plate 124. In the extended state, the end faces of the first support plate 115 and the second support plate 124 on the same layer abut against each other, restricting the second vehicle body 120 from sliding closer to the first vehicle body 110. The second support plate 124 has an unfolded state connected to the second vehicle body 120 and a folded state. The first vehicle body 110 is provided with a storage area 116 for storing the second support plate 124 in the folded state. In the figure, the second support plate 124 includes a main body 1241 and wings 1242 hinged to both sides of the main body 1241. In the unfolded state, the two wings 1242 abut against and are flat with the main body 1241. In the folded state, the two wings 1242 rotate and overlap with the main body 1241, reducing the width of the second support plate 124.

[0086] A storage plate 117 is provided between two opposing first crossbars 114 on the corresponding layer of the first vehicle body 110. A storage area 116 is formed between the storage plate 117 and the first support plate 115. The second support plate 124 in the folded state can be inserted into the storage area 116. When the frame 100 is switched to the folded state, the second crossbar 122 of the second vehicle body 120 closes the opening of the storage area 116, preventing the second support plate 124 from coming out.

[0087] In one embodiment, a limiting mechanism is provided between the slidingly nested first crossbar 114 and the second crossbar 122, the limiting mechanism including:

[0088] The first pin 231 is movably inserted through the first crossbar 114;

[0089] The first insertion hole is provided on the connecting rod 123, and when the frame 100 is in the retracted state, the first pin 231 is inserted into the first insertion hole to restrict the sliding of the first vehicle body 110 and the second vehicle body 120.

[0090] The second insertion hole is provided on the connecting rod 123. When the frame 100 is in the extended state, the first pin 231 is inserted into the first insertion hole to restrict the sliding of the first vehicle body 110 and the second vehicle body 120. The first insertion hole and the second insertion hole are arranged at intervals along the sliding direction of the second vehicle body 120.

[0091] See Figure 3 , Figures 7-11 and Figure 15The trolley 1000 includes a first handle 510 and a second handle 520 mounted on a first body 110. The first handle 510 is positioned along the length direction, and the second handle 520 is movably positioned along the width direction. A first camera 310 faces the width direction and is opposite to the second handle 520. This design allows the operator to grip the second handle 520 and push the trolley 1000 closer to the medicine shelf storage area. The operator's grip on the first handle 510 also allows the trolley 1000 to move relative to the medicine shelf storage area.

[0092] Among them, the first handle 510 is mainly used for daily pushing, while the second handle 520 is set on the first vehicle body 110 and has a usage posture away from the first vehicle body 110 and a storage posture close to the first vehicle body 110, reducing the width of the trolley 1000 during daily movement and making it more flexible to move.

[0093] In the diagram, two adjacent first columns 113 have protruding connecting seats 118. The second handle 520 is a U-shaped rod with both ends hinged to the corresponding connecting seats 118. In the use posture, the U-shaped rod is parallel to the horizontal plane, and in the storage posture, it is perpendicular to the horizontal plane and close to the first column 113. The connecting seat 118 has a waist-shaped groove 1181 extending in the width direction. The two ends of the U-shaped rod are rotatably engaged with the waist-shaped groove 1181 of the corresponding connecting seat 118 by pins. The first column 113 has limiting holes 1131 for the two ends of the U-shaped rod to be inserted. In the use posture, the U-shaped rod is inserted into the limiting hole 1131 by force and is restricted from rotating by the hole wall of the limiting hole 1131. When storing, the U-shaped rod is pulled outward to exit the limiting hole 1131 and rotates under the action of gravity to switch to the storage state.

[0094] In one embodiment, the mobile medicine box 400 includes a box body and a lid that cooperate with each other. The box body or lid is equipped with an electric lock and a display screen for dynamically displaying a QR code. The QR code is used to unlock the electric lock; the electric lock is unlocked after the barcode scanner scans the QR code.

[0095] Medicines are packed, and the correct types and quantities of medicines are transferred to the mobile medicine box 400 on the right under the camera. According to the medicine classification (packaging classification: loose injections, whole boxes of injections, loose tablets, whole boxes of tablets, large bags / large-volume bottles of infusion; nature classification: refrigerated medicines, routine medicines, controlled drugs, high-risk medicines), they are rationally placed into their corresponding storage areas, including: loose injection storage area, whole box medicine storage area, psychotropic and narcotic drug storage area, and refrigerated medicine storage area. Different storage areas do not interfere with each other and the space is flexible.

[0096] The medicine box locking system includes an electronic lock, QR code generation, and information storage. After the medicine is dispensed, the user confirms the information on a tablet / touchscreen LCD, closes the lid of the transfer box, and the transfer box automatically locks. A QR code is generated on the display screen, and the information of the person who dispensed the medicine and the dispensing time are saved to the background database.

[0097] The system uses a location-based transfer system. Dispensing staff transfer the locked portable medicine box from the cart to a service worker, who then promptly delivers it to the department's nursing station. The IoT card inside the portable medicine box allows for real-time location tracking via a local wireless network; many GPS and BeiDou positioning devices are currently available on the market.

[0098] Retrieving medicine from the box includes scanning the code to open the box, verifying the medicine, and saving the record.

[0099] After receiving the medicine transport box, the nurse scans the code to open it. The computer connected to the barcode scanner then uses a program to retrieve the data from this temporary medication dispensing form.

[0100] To verify the medications, the nurse checks each medication in the transport box on the computer. After verification and confirmation, the lid is closed, and a new QR code is generated on the small LCD screen on the lid.

[0101] Records are saved, including the information of the person picking up the medication and the time of pickup, in the backend database. Each time medication is picked up, the box is opened by scanning a QR code. After the medication is picked up, a new QR code is generated, a record is created, and saved.

[0102] This application presents a drug dispensing cart that integrates drug confirmation and monitored dispensing. Its greatest advantage lies in enabling pharmacists to achieve precise drug dispensing through information technology. Data-driven and visual recognition technologies automatically verify drugs, reducing some potential errors associated with manual dispensing. Compared to existing dispensing carts of the same size, this multi-functional cart is more practical and suitable for the future needs of grassroots hospitals with limited resources in establishing information-based and traceable drug dispensing systems in ward pharmacies. Furthermore, when not in use and unloaded, the cart frame can be switched to a storage state to reduce floor space, and the frame's position can be adjusted according to the load capacity.

[0103] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification.
