Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and in particular to a drug dispensing system based on process traceability. Background Technology
[0002] Current hospital drug dispensing mainly includes manual and automated dispensing in outpatient departments, and manual dispensing and PIVAS (Pharmacy Inpatient Drug Delivery System) in inpatient departments. In grassroots hospitals with insufficient resources and scale, inpatient medications are primarily dispensed by a central pharmacy on a departmental basis, transported by workers, and reimbursed by nurses based on paper lists. This often results in errors such as incorrect dispensing (variety, quantity, specifications) or omissions. In today's increasingly complex patient population and the challenging medical environment of multiple disciplines and diseases, both pharmacists and nurses face higher demands on drug dispensing and usage. In recent years, to strengthen medical quality and safety management and continuously improve the level of medical quality and safety, the National Health Commission organized the formulation of the "National Medical Quality and Safety Improvement Goals" for three consecutive years from 2022 to 2024. Therefore, information-based, fully traceable dispensing and distribution is particularly crucial to address the numerous uncertainties and safety hazards in the current drug dispensing and distribution process for inpatients in grassroots hospitals, as well as the inability to trace errors after they occur, thereby hindering the improvement of pharmaceutical and clinical services.

[0070] See Figures 1-7This application provides a drug dispensing system based on process traceability, including a drug storage rack, a dispensing trolley (hereinafter referred to as trolley 1000), a transfer medicine box 400, and a mobile terminal. The drug storage rack includes multiple unit cabinets, each unit cabinet is used to hold medicines, and the drug storage rack has a first display screen that provides a first QR code. The first QR code carries information related to the medicine, such as the name of the medicine and the weight information of the medicine.
[0071] The trolley 1000 is equipped with a liftable data acquisition component and a weighing platform 200. The data acquisition component is used to acquire image information from the medicine storage rack and the weighing platform 200. Specifically, the data acquisition component is used to acquire and recognize the first QR code. The recognition method includes transmitting the image information to the backend, where the backend recognizes the first QR code in the image information and obtains the weight information of the corresponding medicine. The weighing platform 200 is used to measure the weight of the medicine for verification of the weight information. Subsequently, the weighing platform 200 calculates the weight information, or the data acquisition component transmits the weight information to the backend for calculation. The specific calculation is described in the following embodiment.
[0072] The transport medicine box 400 includes a box body and a lid that cooperate with each other, and medicines for storing medicines whose weight information has been verified. The lid is equipped with an electric lock and a second display screen that provides a second QR code. The mobile terminal 210 collects the second QR code to unlock the electric lock, and the operator then puts the verified medicines into the transport medicine box 400.
[0073] The trolley 1000 is used to transfer medicines in the medicine storage rack 700, and to verify and confirm the type, quantity, and weight 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.
[0074] The trolley 1000 includes a frame 100, which includes a first body 110 and a second body 120. Wheels 150 are mounted on the bottom of both the first and second bodies 110. The second body 120 slides relative to the first body 110 and has a folded-up 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 its width. A medicine box 400 is placed on the frame 100 for storing medicines. Both the first and second bodies 110 and 120 have spaces for placing the 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.
[0075] A weighing platform 200 is installed on the first vehicle body 110 to measure the medicines from the storage rack, 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 storage rack and the weighing platform. This image information includes at least the entire process of the medicines moving from the storage rack to the transfer 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.
[0076] This application provides a method for dispensing medicines in a ward pharmacy, including:
[0077] S01, assign drug codes; S02, after assigning drug codes, put the drug on the shelf;
[0078] S100, retrieving medication from the shelf includes:
[0079] 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.
[0080] The "code" assigned to the drug in S01 is in the form of a QR code, namely the first QR code mentioned above. The "code" is set on the label holder at the front of the medicine shelf; 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.
[0081] The drug traceability code is extracted to generate a "code" for drug coding: the total traceability code on the outer packaging of the drug entering the hospital pharmacy is used as the basis for the code, and a dynamic "code" is set on the medicine 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 the label holder of the medicine shelf through a small LCD screen (i.e., a type of first display screen).
[0082] 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".
[0083] 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.
[0084] In S110, a medication list is retrieved. A tablet / touchscreen LCD is used to display the medication 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, the medications are arranged according to the temporary dispensing list, from top to bottom. The indicator light for each medication entry flashes / turns red. Each time a medication is dispensed, its information entry turns gray. The HIS system is linked to the data acquisition component; for example, after the medication is verified and placed in the transport medicine box, a completion message is transmitted to the HIS system.
[0085] The temporary medication dispensing schedule is shown below:
[0086]
[0087] Once a target drug is confirmed, the screen displays its important attributes, such as: similar drugs, high-risk drugs, psychotropic drugs, refrigerated drugs, easily confused drugs, and drugs with multiple specifications; it also displays drug image comparisons, highlights important information such as quantity, etc.
[0088] In the later stage of database construction, models were established for relevant data such as the frequency of medication errors and the efficiency of drug dispensing, so as to build a digital intelligence platform for later program optimization, departmental medication patterns, and even the outbreak, prediction, and prognosis of infectious diseases.
[0089] 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:
[0090] First embodiment (scanning the code to confirm the quantity of medicine):
[0091] 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.
[0092] In the second embodiment (using QR codes to verify the quantity of drugs):
[0093] Medication dispensing 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, dispensing 13 doses of medication involves confirming the medication via the QR code. The weighing device offers multiple conversion modes: weight of a 5-dose box. 2+3 loose items; 5 whole boxes + 8 loose items; 13 loose items; the dispenser can take any corresponding quantity, place the medicine on the weighing platform, and the screen will automatically alert if the weight is overweight or underweight, requiring the dispenser to intervene for confirmation. After the weight and quantity are correctly converted and matched, the medicine is placed in the multi-functional transport medicine box under camera monitoring, the medicine information turns gray, and the next medicine is scanned and distributed.
[0094] In the third embodiment (verifying the quantity of medicines using a combination of QR codes and AI visual recognition):
[0095] 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.
[0096] 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 dispensing quantity in the ward's drug 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, and each drug is maintained in the database based on its packaged and individual weights. It also has multiple measurement mode code instructions. The retrieved drugs are placed on the weighing platform, which provides various conversion modes, such as 13 vials to the weight of a 5-vial box. 2+3 loose items; 5 boxes of medicine plus 8 loose items; 13 loose items; The dispenser can take any corresponding quantity, place the medicine on the weighing platform, and the weighing platform will automatically calculate the weight. If the weight is overweight or underweight, the screen will automatically warn and require the dispenser to intervene for confirmation. If the weight and quantity match, it is correct.
[0097] 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.
[0098] Regarding the specific structure of the frame 100:
[0099] 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 storage rack and is used to acquire and identify real-time images (a type of image information) of medicines being removed from the medicine storage rack. At the same time, the image information is transmitted to the control cabinet 600, where the control cabinet, in conjunction with the cloud server, identifies and judges the "code" in the image information.
[0100] The second camera 320 faces the weighing platform 200, which is placed horizontally, 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 dome cameras, for example, and have 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 area covered by the second camera 320 includes both the weighing platform 200 and the transport medicine box 400, meaning it can monitor the movement of medications from the weighing platform 200 to the transport medicine box 400.
[0101] 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.
[0102] The data collection component also includes a mobile terminal 210 mounted on the first vehicle body. The mobile terminal 210, such as the aforementioned tablet computer, is used to open the transport medicine box 400. The transport medicine box 400 has a display screen that dynamically generates a QR code for the mobile terminal 210 to scan. After scanning and confirmation, the transport medicine box 400 is opened.
[0103] like Figure 7 and Figure 12 As shown, a platform 111 is provided on the top layer of the first vehicle body 110, and a weighing platform 200 and a mobile terminal 210 are detachably mounted on the platform 111. The weighing platform 200 can be removed for maintenance, charging, etc. The mobile terminal 210 can be detached and held by hand for easy operation.
[0104] 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 mobile terminal 210 is connected to the end link via magnetic attraction. Movement of the robotic arm allows the mobile terminal 210 to have a tilted posture that detaches from and moves away from the platform 111, and a storage posture that retracts into the platform 111. The mobile terminal 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, and the mobile terminal 210 does not match the corresponding position on the platform 111, the platform 111 will lift the mobile terminal 210 away from the robotic arm 140. The operator can then re-insert the mobile terminal 210 into the platform 111. The robotic arm 140 is electrically connected to the control cabinet 600, and corresponding buttons are provided on the platform 111 to control the robotic arm 140 via the control cabinet 600.
[0105] 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.
[0106] 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 transport medicine boxes or other items.
[0107] 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 transport medicine box 400, so that the opening of the transport medicine box 400 can be done without interference.
[0108] 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. In the unfolded state, the second support plate 124 is placed above the frame of the second vehicle body 120 and is the same width as the second vehicle body 120 and the first support plate.
[0109] 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.
[0110] In one embodiment, a limiting mechanism is provided between the slidingly nested first crossbar 114 and the second crossbar 122, the limiting mechanism including:
[0111] The first pin 231 is movably inserted through the first crossbar 114;
[0112] 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.
[0113] 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.
[0114] See Figure 3 , Figures 7-11 and Figure 15 The 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. The operator's grip on the first handle 510 also allows the trolley 1000 to move relative to the medicine shelf.
[0115] 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.
[0116] 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.
[0117] Under the surveillance of the first and second cameras, the correct types and quantities of medicines are transferred to the right-side transfer medicine box 400. 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 narcotics, psychotropic drugs, high-risk medicines), they are rationally placed into their respective storage areas, including: loose injection storage area, whole box medicine storage area, psychotropic drug storage area, and refrigerated medicine storage area. Different storage areas do not interfere with each other and the space is flexible.
[0118] The locking mechanism for the medicine box includes: an electronically controlled lock, generation of a second QR code, and information storage. After the medicine dispensing is completed, the user confirms the information on a tablet / touchscreen LCD, closes the lid of the transfer box, and the medicine box automatically locks. A second QR code is generated on the second display screen, and the information of the person who previously dispensed the medicine and the dispensing time are saved to the background database.
[0119] The system uses a location-based transfer mechanism. Dispensing staff transfer the locked transport kit from the trolley to a service worker, who then promptly delivers it to the department's nursing station. The IoT card inside the transport kit allows for real-time location tracking via a local wireless network; many GPS and BeiDou positioning devices are currently available on the market.
[0120] Retrieving medicine from the box includes scanning the code to open the box, verifying the medicine, and saving the record.
[0121] 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.
[0122] 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.
[0123] 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.
[0124] 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.
[0125] See Figures 16-25 This application provides a multifunctional transport medicine box. The transport medicine box 400 includes a first box body 410 and a first box cover 420 that cooperate with each other. The first box body 410 includes a low temperature zone 401 and a normal temperature zone 402. The normal temperature zone 402 is divided into a first unit zone 4021 and a second unit zone 4022.
[0126] A drawer assembly 440 is movably installed within the first unit area 4021. The movability can be detachable, hinged, or sliding. The drawer assembly 440 is positioned above the first unit area 4021, and the first unit area 4021 has storage space below the drawer assembly 440 (hereinafter referred to as the lower space). The drawer assembly 440 does not occupy the entire upper space of the first unit area 4021, but only a portion of it. For ease of use, the drawer assembly 440 has an initial position within the housing 410 (e.g., ...). Figure 18and Figure 21 ) and the clearance area at the bottom of the first unit area 4021 (such as Figure 25 When drawer assembly 440 is in its initial position, items can still be placed in the lower space, but this is somewhat inconvenient. If drawer assembly 440 is empty and not in use, it can be moved to a less confined position, fully opening up the upper space and facilitating the placement of items in the lower space. The position of drawer assembly 440 can be flexibly adjusted to maximize space utilization as needed.
[0127] In combination Figure 26 A liquid container 450 is provided in the second unit area 4022. The liquid container 450 includes a second box body 451 and a second box lid 452. The liquid container 450 is used, for example, to store anesthetic drugs. The first box lid 420 and the second box lid 452 are equipped with electric locks and a display screen 430 for dynamically displaying QR codes. The QR code generated by the display screen is used to unlock the corresponding electric lock. In actual use, the operator scans the QR code on the display screen using a mobile terminal. After confirmation, the electric lock unlocks, allowing the corresponding box lid to be opened for drug storage and retrieval. Other usage methods are described in the following embodiments.
[0128] This application discloses a multifunctional transport medicine box that can store medicines at room temperature or requiring low-temperature storage. The drawer assembly is flexible enough to adapt to different storage methods, offering adaptable space to meet the storage needs of various medicines. Furthermore, the electronic lock and QR code-generating display screen work together to provide information-based, safe, and reliable closed transport. Compared to existing transport medicine boxes, this application's multifunctional transport medicine box can accommodate more varieties and quantities of medicines, ensuring safety, reliability, and traceability.
[0129] The transport medicine box 400 also includes a third box cover 421 that cooperates with the first box body 410. The third box cover 421 covers the second unit area 4022, and the first box cover 420 covers the first unit area 4021 and the insulation area 401. The third box cover 421 and the first box body 410 are normally locked together.
[0130] The first box 410 and the second box 451 are also equipped with IoT cards for providing location information. These cards send location-related information, allowing the pharmacy to track the location of all medicine boxes throughout the hospital and monitor their status, including whether they are empty and information about the medicines inside, such as type and quantity. This enables efficient dispensing and transport. When medicines are retrieved, the operator verifies the transaction on a device (e.g., a tablet). Similarly, when medicines are placed into the transport medicine box 400, the operator needs to confirm the addition on the device. This ensures the pharmacy obtains accurate medicine information within the transport medicine box 400, enabling more precise dispensing.
[0131] The low-temperature zone 401 includes a medicine storage tank 4011 and a refrigeration device. The medicine storage tank 4011 is integrally installed in the first housing 410 or is independently configured and removable from the first housing 410. The tank wall of the medicine storage tank 4011 is provided with an insulation layer. The refrigeration device is located below the medicine storage tank 4011 to cool it down. The side wall of the first housing 410 has heat dissipation holes that match the hot end of the refrigeration device and a corresponding charging port. A rubber ring is provided on the first housing cover 420 to seal the top cover of the medicine storage tank 4011, providing good insulation.
[0132] Drawer assembly 440 includes multiple drawers that slide and nest sequentially. Each drawer has a nested, closed state and an extended, exposed state. In its recessed position, drawer assembly 440 is located at the corner of the first unit area 4021. Drawer assembly 440 is used to store small and lightweight medications such as small injections or ampoules. When the drawer assembly is empty, it switches to the closed state (e.g., ...). Figure 18 When medicines need to be stored, the appropriate number of drawers can be removed based on the quantity of medicines. For example... Figure 21 and Figure 23 The drawer assembly 440 shown includes three drawers, which are, from the outside in, a first drawer 441, a second drawer 442, and a third drawer 443. The outer contour of the third drawer 443 occupies all the internal space of the second drawer 442, and the outer contour of the second drawer 442 occupies all the internal space of the first drawer 441. Therefore, the three drawers have approximately the same capacity. Let the capacity of one drawer be A, the capacity of n drawers be nA, and the number of medicines to be placed be X.
[0133] When X < A, pull out the third drawer 443 and fill the third drawer 443 with medicine;
[0134] When A < X < 2A, take out the second drawer 442 and the third drawer 443, and put the medicine into the corresponding drawer;
[0135] When 2A < X < 3A, pull out the second drawer 442 and the third drawer 443, and put the medicine into the corresponding drawer.
[0136] In one embodiment, the first unit area 4021 has a rectangular structure, and support platforms 460 are provided on the adjacent side walls. When the drawer assembly 440 is in the use position, it is placed on the support platform 460. The drawer assembly 440 and the support platform 460 are connected by a limiting mechanism to keep the drawer assembly 440 in the use position.
[0137] In the diagram, the limiting mechanism includes a limiting block 463 protruding from the support platform 460 and a limiting groove 4411 disposed on the outermost drawer. The limiting groove 4411 and the limiting block 463 cooperate with each other, for example, by engaging. Alternatively, in another embodiment, the limiting mechanism includes a first magnetic member 471 disposed on the support platform 460 and a second magnetic member 472 disposed on the drawer assembly 440 and engaging with the first magnetic member 471. The magnetic form facilitates disassembly. Of course, both limiting mechanisms can be used simultaneously.
[0138] Each drawer is equipped with a second magnetic 472. In the retracted state, the second magnetic 472s of adjacent drawers attract each other to restrict the inner drawer from extending. There are multiple first magnetic 471s, some of which extend along the extension direction of the drawer and attract each other with the second magnetic 472 of the corresponding drawer to keep the drawer in the extended state. The support platform 460 is L-shaped, including a first section 461 extending along the sliding direction of the drawer and a second section 462 perpendicular to one end of the first section 461. As mentioned above, the limiting block 463 protrudes from the second section 462, and some of the first magnetic 471s are spaced apart on the first section 461.
[0139] The aforementioned drawer assembly 440 is located at the corner of the first unit area 4021 in the avoidance position. For example... Figure 24 and Figure 25 As shown, in one embodiment, the side wall and / or bottom wall of the first unit area 4021 are provided with a third magnetic member 473. When the drawer assembly 440 is in the avoidance position, the third magnetic member 473 and the second magnetic member 472 are attracted to each other to restrict the relative movement of the drawer assembly 440.
[0140] See Figure 19 and Figure 20 The first unit area 4021 is slidably provided with partitions 480, and the number of partitions 480 is one or multiple as shown in the figure, dividing the first unit area 4021 into multiple sections. Among them, the two opposite side walls of the first unit area 4021 are provided with slide rails 490, and the two ends of the partitions 480 are slidably disposed in the slide rails 490. The slide rails 490 have slide grooves 491 along the sliding direction and multiple slots 492 are provided at intervals. The slots 492 are connected to the slide grooves 491, and the two ends of the partitions 480 are engaged in the slots 492 to restrict their own sliding.
[0141] like Figure 22 and Figure 24 As shown, a fourth magnetic 474 is provided at the bottom of the partition 480, and a fifth magnetic 475 is provided at the bottom of the first unit area 4021. The number and position of the fifth magnetic 475 correspond to the slot 492 to keep the partition 480 vertical and prevent it from shaking.
[0142] For the structure of the liquid container 450:
[0143] See Figures 26-29 In one embodiment, the bottom of the second housing 451 is provided with an empty bottle holding area 453, and a drain tray 454 is slidably disposed at the bottom of the empty bottle holding area 453. A replaceable absorbent material layer is laid below the drain tray 454. Especially for anesthetic drugs, the residual liquid of the drug is still a controlled substance, so an electronic lock needs to be installed, and a specialist must open it to handle the residual liquid in the absorbent material layer and the drain tray in accordance with regulations.
[0144] The drug dispensing system proposed in this application is portable and can adapt to the needs of inpatient wards for more specifications and varieties of drugs. It meets the requirements of paperless dispensing, accurate distribution, and traceability, thereby improving the accuracy of drug dispensing.
[0145] 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. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.
[0146] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
