Description

Technical Field

[0001] The present invention relates to the technical field of Chinese medicine granule dispensing, and in particular to a multi-channel coordinated dispensing method and system. Background Art

[0002] In the field of Chinese medicine granule dispensing, most dispensing is done on a single machine with a single task. Bottles are manually picked up and placed, and one prescription must be completed before the next one can be prepared. Dispensing prescriptions are queued and processed in sequence.

[0003] Patent No. CN114435637A discloses a Chinese medicine granule dispensing system, which is equipped with bag holders to carry medicine bags. The bags are circulated along a preset route so that the bags pass through all medicine bottles in sequence. The medicine bottles are automatically opened at the corresponding medicine bottle positions to fill the corresponding amount of medicine. Although the dispensing method of this dispensing system can replace manual labor, it is equipped with multiple bag holders to operate synchronously. When one bag holder pauses under a medicine bottle for filling, the other bag holders need to pause synchronously. When the bag holders are closely arranged and there are many prescriptions to be processed, the bag holders need to pause for filling almost every time they move forward to a medicine bottle position, resulting in low prescription processing efficiency and long waiting time for patients to get medicine. In addition, when any part of the system equipment fails, the entire equipment may be stopped and the filling task cannot be performed. Summary of the Invention

[0004] The present invention provides a multi-channel coordinated dispensing method and system to solve the technical problems of low prescription processing efficiency, low medicine dispensing efficiency and long waiting time in the existing Chinese medicine granule dispensing system.

[0006] S1. Allocate high-frequency medicine bottles according to the frequency of use of the target drug library in the first channel path, each of which contains a medicine, and place all medicine bottles including the target drug library in the second channel path in sequence;

[0007] S2. Obtain the target prescription and assign the filling task to the first or second channel for bag delivery according to the content of the target prescription;

[0008] S3. When the medicine bag passes through the medicine bottle corresponding to the target prescription, the medicine bottle will be filled with the medicine corresponding to the target prescription content in the medicine bag;

[0009] S4. Take out the bag and complete the filling of the medicine in the target prescription.

[0010] As a further improvement of the above technical solution, the dispensing system includes a plurality of bag discharging devices, which are used to seal the medicine bags and transport them from the bag-moving channel to the medicine discharging end of the dispensing system. The dispensing method also includes:

[0011] The medicine bottles on the bag-moving channel are arranged in order from high to low according to the frequency of taking the medicines in the bottles. At least one bag-moving device is arranged at the outlet end of the bag-moving channel, and the remaining bag-moving devices are arranged on the path of the bag-moving channel.

[0012] As a further improvement of the above technical solution, the dispensing system includes a transfer device for transferring the medicine bottle.

[0013] As a further improvement of the above technical solution, step S2 includes:

[0014] S21. Obtain target prescription;

[0015] S22. Determine the coverage ratio of the drugs in the target prescription covered by the drugs in the first channel path. If the coverage ratio is less than a first preset value, assign the filling task to the second channel. If the coverage ratio is greater than or equal to the first preset value, assign the filling task to the first channel.

[0016] S23. Transfer the medicine bottles corresponding to the drugs in the target prescription content that are missing on the first channel path to the first channel through the transfer device.

[0017] As a further improvement of the above technical solution, when the medicine bottles corresponding to the drugs in the target prescription content that are missing on the path of the first channel are transferred to the first channel by the transfer device, the dispensing method further includes:

[0018] The transfer device transfers the corresponding medicine bottle on the second channel path to the first channel. After the target prescription content on the first channel is missing and the medicine filling is completed, the transfer device transfers the corresponding medicine bottle and resets it to the second channel path.

[0019] As a further improvement to the above technical solution, the dispensing system is provided with a transition device for placing medicine bottles of less frequently used medicines. When the medicine bottles corresponding to the medicines in the target prescription content that are missing on the first channel path are transferred to the first channel by the transfer device, the dispensing method further includes:

[0028] According to another aspect of the present invention, a multi-channel coordinated adjustment system is provided for implementing any of the above adjustment methods.

[0029] The present invention has the following beneficial effects: the dispensing method sets at least two types of channels in the dispensing system, distributes frequently used medicines to the medicine bottles on the filling mechanism of the first channel, and distributes all medicines in the target medicine library to the second channel, so that the path length of the first channel is greatly shortened compared with the path length of the second channel, and the travel of the medicine bag in the first channel is greatly shortened compared with the travel of the second channel. After the system recognizes the prescription and inputs the prescription into the system, it determines whether the medicine of the target prescription is within the range of medicines covered by the first channel. If it is within the range, it can be distributed to the first channel for filling and dispensing, avoiding passing through the longer channel including all medicines, so that its travel is shortened. This significantly shortens and significantly improves filling and dispensing efficiency, reducing time consumption. If the target prescription drug is not within the coverage of the first channel, it can be assigned to the second channel for bag delivery, passing under all drug bottles of the corresponding drug category and filling at the corresponding position. Or, when the first channel reaches its limit, the second channel can be temporarily called for bag delivery, reducing waiting time. Furthermore, each channel can be assigned multiple filling tasks and run simultaneously to handle the filling and dispensing of multiple prescriptions. That is, multiple bags enter the corresponding channel in sequence for filling, without having to wait for the previous bag to be filled. Parallel prescription dispensing further increases the number of fills, improving processing efficiency and filling efficiency for large prescriptions.

DETAILED DESCRIPTION

[0036] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] Reference Figures 1 to 3 A preferred embodiment of the present invention provides a multi-channel coordinated dispensing method, including a dispensing system, wherein the dispensing system has a bag-moving mechanism, a bag-moving channel, and a filling mechanism arranged along the bag-moving channel path. The filling mechanism is used to install medicine bottles 22 and to control the opening and closing of corresponding medicine bottles 22. The bag-moving mechanism is used to move medicine bags 9 along the bag-moving channel path. The bag-moving channel includes at least one first channel 11 and at least one second channel 12. The dispensing method includes:

[0038] S1. Based on the frequency of use of drugs in the target drug library, the first channel 11 is allocated to the most frequently used medicine bottles 22. Each medicine bottle 22 contains a single drug, and each filling mechanism is equipped with a corresponding medicine bottle 22. The second channel 12 is then sequentially allocated to the medicine bottles 22 containing all drugs in the target drug library. It should be noted that the target drug library can include all drugs in the hospital's drug library, or exclude all other drugs with extremely low frequency of use by the hospital. This should be configured based on the adaptability of the specific application environment. In this embodiment, the first channel 11 is configured to accommodate drugs based on the actual application environment. These drugs can cover 40%-60% of the hospital's prescriptions.

[0039] S2. Obtain the target prescription and assign the filling task to the first channel 11 or the second channel 12 for moving the medicine bag 9 according to the content of the target prescription; it should be noted that the dispensing system has an identification system for receiving and identifying the prescription (such as an electronic prescription) and then assigning the filling task to the dispensing system; the dispensing system has a main control system for implementing the dispensing method of this embodiment, and the identification system is integrated into the main control system. The identification system can be a QR code scanning, text recognition, computer input command, etc. The specific implementation methods of the main control system and the identification system are mature existing technologies and will not be elaborated on here; the dispensing system includes a bag feeding mechanism 31, which is respectively provided at the outlet end of the first channel and the outlet end of the second channel to provide medicine bags 9 for the two channels;

[0040] S3. When the medicine bag 9 passes through the medicine bottle 22 including the corresponding medicine in the target prescription, the medicine bottle 22 will fill the medicine bag 9 with the medicine corresponding to the target prescription content; specifically, the filling mechanism controls the opening and closing of the bottle mouth of the medicine bottle 22 to achieve the output filling of the medicine;

[0041] It should be noted that if the dispensing system recognizes and accepts multiple prescriptions, steps S2 to S3 are repeated until the allocation of filling tasks corresponding to all target prescriptions is completed;

[0042] S4. Bag out, completing the filling of the target prescription drugs; that is, when the prescription drugs are filled and transported to the terminal position (such as the bag channel outlet), the bag is sealed and output by the dispensing system, and then the bag can be taken away by the staff or the patient 9.

[0043] It should be noted that the first channel 11 can be one or more, and similarly, the second channel 12 can be one or more, and can be set according to comprehensive considerations such as site conditions, equipment customization scale, and medicine output frequency;

[0044] It can be understood that the present dispensing method sets at least two types of channels in the dispensing system, distributes frequently used medicines to the medicine bottles 22 on the filling mechanism of the first channel 11, and distributes all medicines in the target medicine library to the second channel 12, so that the path length of the first channel 11 can be greatly shortened compared with the path length of the second channel 12, and the travel of the medicine bag 9 in the path of the first channel 11 can be greatly shortened compared with the travel of the second channel 12. After the system recognizes the prescription and inputs the prescription into the system, it determines whether the medicine of the target prescription is within the range of medicines covered by the first channel 11. If it is within the range, it can be distributed to the first channel 11 for filling and dispensing, avoiding passing through the medicine bag 9 including The longer-stroke channel for all medicines greatly shortens their stroke, significantly improves the filling and dispensing efficiency, and reduces time consumption. If the target prescription medicine is not covered by the first channel 11, it can be allocated to the second channel 12 for bag movement, and pass under the medicine bottles 22 of all medicine categories in turn and be filled at the corresponding position; at the same time, each channel can be allocated multiple filling tasks and run simultaneously to perform filling and dispensing of multiple prescriptions, that is, multiple medicine bags can enter the corresponding channel in sequence for filling, without waiting for the previous medicine bag to be filled; parallel prescription dispensing further increases the number of fillings, and improves the processing efficiency and filling efficiency in the case of a large number of prescriptions.

[0045] In this embodiment, the dispensing system includes a plurality of bag dispensing devices 8, which are used to seal the medicine bags 9 and transport them from the bag feeding channel to the medicine dispensing end of the dispensing system. The dispensing method also includes:

[0046] The medicine bottles 22 on the bag-feeding channel are arranged in descending order according to the frequency of use of the medicines in the medicine bottles 22. At least one bag-discharging device 8 is arranged at the outlet end of the bag-feeding channel, and the remaining bag-discharging devices 8 are arranged on the path of the bag-feeding channel.

[0047] In this embodiment, the dispensing system includes a transfer device for transferring the medicine bottle 22;

[0048] Furthermore, when allocating filling tasks according to the content of the target prescription, the present adjustment method specifically includes:

[0049] S21. Obtaining the target prescription; specifically, the aforementioned recognition system identifies the prescription in multiple ways and feeds it back to the main control system. The main control system then allocates the filling task according to the present dispensing method, and allocates the filling task to the first channel or the second channel according to the content of each target prescription. The target channel assigned with the filling task is allocated medicine bag 9 to the entrance end of the target channel and is driven by the bag moving mechanism to move the bag;

[0050] If the ratio of the number of medicine bags 9 located on the path of the first channel 11 to the number of medicine bags 9 located on the path of the second channel 12 exceeds a second preset value, the subsequent medicine bags 9 are distributed to the second channel 12 until the above ratio is lower than the second preset value. Since the first channel 11 has a shorter stroke than the second channel 12 and both of them are medicines with a higher frequency of use, an overload may occur, resulting in a longer queue time for subsequent prescriptions or uneven distribution of prescriptions between the two channels. Based on the above distribution method, the prescription processing effect and filling efficiency can be further improved when the prescription volume is large; wherein, the second preset value is set according to the actual application scenario, the specifications of the dispensing system, etc.;

[0051] The allocation method can also be as follows: if the number of medicine bags 9 located on the path of the first channel 11 exceeds a third preset value, the subsequent medicine bags 9 are allocated to the second channel 12. The two allocation methods can be applied simultaneously or separately.

[0052] S22. Determine the coverage ratio of the drugs in the target prescription covered by the drugs in the first channel 11. If the coverage ratio is less than the first preset value, the filling task is assigned to the second channel 12. If the coverage ratio is greater than or equal to the first preset value, the filling task is assigned to the first channel 11.

[0053] Among them, the setting of the first preset value can be positively correlated with the number of drugs included in the target prescription, that is, the first preset value increases as the number of drugs included in the target prescription increases. The higher the number of drugs, the higher the required coverage ratio, and the number of drugs allowed to be missing is kept within a smaller range; for example, when judging according to the above method, a prescription including 2-4 drugs is required to cover all drugs, a prescription including 5 drugs is required to cover 4 drugs, a prescription including 7 drugs is required to cover 6 drugs, and a prescription including 11 drugs is required to cover 9 drugs; based on this, the coverage ratio can be set in the system according to the above calculation method, and the corresponding required coverage quantity lower limit can also be set according to the different numbers of drugs;

[0054] S23. The medicine bottle 22 corresponding to the drug in the target prescription content missing on the path of the first channel 11 is transferred to the first channel 11 by the transfer device;

[0055] Specifically, the transfer device transfers the corresponding medicine bottle 22 on the path of the second channel 12 to the first channel 11. After the target prescription content on the first channel 11 is missing and the medicine filling is completed, the transfer device transfers the corresponding medicine bottle 22 and resets it to the path of the second channel 12. Based on this, when a very small number of types of medicines are missing on the path of the first channel 11, the medicine bottle 22 containing the corresponding medicine on the second channel 12 is transferred to the first channel 11 to fill the medicine bag 9, and then resets it to the second channel 12 after the filling is completed, thereby further improving the filling efficiency and ensuring a shorter medicine dispensing time.

[0056] In this embodiment, the dispensing system is provided with a transition device for placing medicine bottles 22 containing drugs with low frequency of use. When the medicine bottles 22 corresponding to the drugs in the target prescription content that are missing on the path of the first channel 11 are transferred to the first channel 11 by the transfer device, the dispensing method further includes:

[0057] When the transition device has a corresponding medicine bottle 22, the corresponding medicine bottle 22 is transferred to the path of the first channel 11;

[0058] Specifically, at least one reserved position is provided on the first channel 11, and a filling mechanism is provided in the reserved position. No medicine bottle 22 is placed in the filling mechanism in normal working state. The reserved position is used to place the medicine bottle 22 transferred to the path of the first channel 11 by the transfer mechanism based on the above-mentioned adjustment method; one or several medicines with the lowest frequency of use are placed on the transition device. When the above-mentioned types of medicines need to be filled, the transfer device moves them to the corresponding reserved position, and resets them to the transition device after the filling is completed; multiple medicines can share one filling mechanism, further shortening the travel of the bag-moving channel and improving the filling efficiency.

[0059] Similarly, at least one reserved position may be provided on the second channel 12 to achieve the above effect.

[0060] In this embodiment, the main control system is further connected to an alarm system, and the filling mechanism is provided with a weight sensor. The dispensing method further includes: when the weight sensor senses that the weight of the corresponding medicine bottle 22 is lower than a set value and / or senses that the weight of the corresponding filling mechanism is lower than a preset value, feedback is sent to the main control system, and the alarm system issues an alarm to remind the user to refill the medicine.

[0061] In this embodiment, the dispensing system is provided with a plurality of bag discharging devices 8, and the dispensing method further includes: setting a bag discharging device 8 at the outlet end of the first channel 11, setting a bag discharging device 8 at the outlet end of the second channel 12, and distributing one or more bag discharging devices 8 on the path of the first channel 11 and / or the path of the second channel 12; the main control system matches the bag 9 with the bag discharging device 8 closest to the unfinished stroke on the channel after the filling is completed, and discharges the bag to the drug discharging end of the dispensing system through the matched bag discharging device 8; the bag 9 that has completed the filling of the corresponding medicine in the channel path can be discharged in advance, and the bag can be sealed by the bag discharging device 8 closest to the unfinished stroke on the path and directly transported to the drug discharging end. The bag 9 does not need to complete the entire stroke of the channel, and can be discharged in advance, thereby further improving the processing efficiency and reducing the waiting time.

[0062] On the other hand, reference Figures 1 to 3This embodiment also provides a multi-channel coordinated dispensing system for implementing the above-mentioned dispensing method of this embodiment. The dispensing system includes an isolation chamber 1, a filling device 2, and a bag feeding device 3. The filling device 2 and the bag feeding device 3 are both arranged in the isolation chamber 1. By setting up the isolation chamber 1, a drug dispensing and storage environment with temperature, humidity, and air cleanliness that meet the requirements is constructed, effectively isolating external contamination and ensuring the purity of the drug.

[0063] The isolation chamber 1 is provided with a bag passage, which includes at least one first passage 11 and at least one second passage 12;

[0064] The filling device 2 includes a filling mechanism and a filling station 21 arranged along the first channel 11 and a filling station 21 arranged along the second channel 12. The filling station 21 is used to set the filling mechanism, which is used to carry the medicine and output the medicine according to the demand. The medicine in this embodiment is a Chinese medicine granule.

[0065] A bag feeding device 3 is provided on the first channel 11 and the second channel 12, respectively. The bag feeding device 3 includes a bag feeding mechanism 31 and a bag holder 32. The bag holder 32 is used to carry the medicine bag 9. The bag feeding mechanism 31 is used to drive the bag holder 32 to circulate along a preset trajectory, so as to drive the bag holder 32 to move along the first channel 11 to the target filling station 21 or along the second channel 12 to the target filling station 21.

[0066] Specifically, the dispensing system has a frame arranged in an isolation chamber 1, for mounting a filling device 2 and a bag feeding device 3; the filling mechanism includes medicine bottles 22 and a filling assembly 221, each of which contains a medicine. The filling assembly 221 is used to control the opening of the bottle mouth of the medicine bottle 22 and drive the medicine in the medicine bottle 22 to be discharged according to the demand;

[0067] The dispensing system also has an identification system for receiving and identifying prescriptions, and then controlling the movement of the bag feeding mechanism 31 so that the bag holder 32 moves along a preset trajectory to the bottom of each target filling station 21 in sequence. The filling mechanism controls the opening and closing of the bottle mouth of the medicine bottle 22 to output the required amount of medicine into the medicine bag 9 of the bag holder 32;

[0068] It can be understood that, by installing the medicine bottle 22 on the filling mechanism and driving the Chinese medicine granules in the medicine bottle 22 to fall down according to the quantity required, and then driving the bag holder 32 to move cyclically along the preset trajectory through the bag feeding device 3, the medicine bag 9 on each bag holder 32 is moved to the bottom of the filling station 21 in turn and receives the medicine output by the filling mechanism, and the Chinese medicine granule filling process of multiple medicine bags 9 is automatically completed, which effectively improves the efficiency of Chinese medicine granule adjustment and ensures the accuracy of filling content; by providing the first channel 11 and the second channel 12, each channel can run simultaneously to perform filling and adjustment of multiple prescriptions, and the number of parallel prescription adjustment and filling is further increased, thereby improving the processing efficiency and filling efficiency of the prescription;

[0069] On the other hand, frequently used medicine bottles 22 can be placed in the filling work of the first channel 11, and medicine bottles 22 including all medicines in the target medicine library can be placed in the second channel 12. The bag moving distance of the first channel 11 is greatly shortened. When the target prescription medicines are within the range of medicines covered by the first channel 11, they are allocated to the first channel 11 for filling and adjustment. The stroke is greatly shortened, which significantly improves the circulation efficiency of the bag holder 32 and the filling and adjustment efficiency, and reduces time consumption.

[0070] It should be noted that the target drug library may include all drugs in the hospital's drug library, or exclude all other drugs that are rarely used by the hospital.

[0071] In this embodiment, the dispensing system includes a transfer device, which includes a manipulator 4 for grabbing a medicine bottle 22 and placing it on a filling assembly 221 of any filling station 21. The manipulator 4 includes an X-axis drive mechanism arranged along the width direction of the frame, a Y-axis drive mechanism arranged on the X-axis drive mechanism along the length direction of the frame, a Z-axis drive mechanism arranged on the Y-axis drive mechanism along the height direction of the frame, and a clamp 44 arranged on the Z-axis drive mechanism and for clamping the medicine bottle 22. The X-axis drive mechanism is used to drive the Y-axis drive mechanism to move along the width direction of the frame, the Y-axis drive mechanism is used to drive the Z-axis drive mechanism to move along the length direction of the frame, and the Z-axis drive mechanism is used to drive the clamp 44 to move along the height direction of the frame. The coordination of the X-axis drive mechanism 41, the Y-axis drive mechanism, and the Z-axis drive mechanism forms a three-axis linkage mechanism for the clamp 44, enabling the clamp 44 to move to any position in the three-dimensional space above the frame, thereby adapting to each filling station 21.

[0072] Furthermore, the X-axis drive mechanism includes two X-axis guide rails respectively arranged at both ends of the frame in the length direction, the X-axis guide rails are arranged along the width direction of the frame, and the Y-axis drive mechanism is mounted on the X-axis guide rails and can move along the X-axis guide rails.

[0073] In this embodiment, the driving structures of the X-axis driving mechanism, the Y-axis driving mechanism and the Z-axis driving mechanism are based on the motor and electric cylinder in the prior art combined with the existing transmission structure such as the lead screw and the slider, which will not be elaborated here.

[0074] In this embodiment, the dispensing system includes a transition device, which includes a transition tray 6. The manipulator 4 is further used to move the medicine bottle 22 on the filling station 21 to the transition tray 6, or to move the medicine bottle 22 on the transition tray 6 to the filling station 21; when a certain type of medicine on the first channel 11 is used up, before replacing the medicine bottle 22 to replenish the medicine, the manipulator 4 can place the empty medicine bottle 22 on the transition tray 6, and the manipulator 4 transfers the medicine bottle 22 of the corresponding medicine type on the path of the second channel 12 to the first channel 11 for filling. After the filling is completed or the medicine is replenished, the medicine bottle 22 is transferred and reset to the path of the second channel 12, and the medicine bottle 22 for replenishing the medicine is transferred to the path of the first channel 11; similarly, when a certain type of medicine on the path of the second channel 12 is used up, if there is such medicine on the path of the first channel 11, the manipulator 4 transfers the medicine bottle 22 of the corresponding medicine type on the path of the first channel 11 to the second channel 12 for filling, and resets it after the filling is completed;

[0075] In some embodiments, the filling mechanism may be provided with a weight sensor for sensing the weight change of the filling assembly 221 and then sending an alarm signal to remind the user to replenish the corresponding medicine when the medicine in the medicine bottle 22 is almost exhausted.

[0076] Furthermore, the number of filling stations 21 on the bag feeding channel is greater than the number of medicine bottles 22 on the corresponding bag feeding channel. Specifically, a reserved position can be set for the first channel 11 and / or the second channel 12. No medicine bottles 22 are placed in the filling component 221 of the reserved position under normal working conditions. The medicine bottles 22 containing the least frequently used medicines are placed on the transition plate 6. When there is a filling task, the corresponding medicine bottles 22 are transferred to the reserved position for filling by the robot 4. After the filling is completed, they are transferred and reset to the transition plate 6. By reserving a reserved position, the medicines with low frequency of use are removed from the channel and placed in the shared reserved position. The system selectively places the corresponding medicine bottles 22 according to the prescription content, which can further shorten the travel of the bag feeding channel and improve the medicine dispensing speed and efficiency.

[0077] In some embodiments, the dispensing system includes an isolator 5, which includes an isolation cavity with a sterilization function (not shown in the figure, the same below), a first inner isolation door (not shown in the figure, the same below) and an outer isolation door. The isolation cavity is used to place items such as medicine bottles 22 and sterilize and disinfect items such as medicine bottles 22. The first inner isolation door and the outer isolation door are both connected to the isolation cavity and are used to open the inner cavity of the isolation cavity to expose the first inner isolation door. The first inner isolation door is set toward a transition tray 6, and the outer isolation door is set toward the outside of the isolation chamber 1; based on this, two transition trays 6 are provided, one transition tray 6 is provided between the first channel 11 and the second channel 12, and the other transition tray 6 is provided close to the isolator 5; it can also be that the setting position of the isolator 5 on the isolation chamber 1 is located between the first channel 11 and the second channel 12.

[0078] A medication application window 13 is provided in the isolation chamber 1 at the position of the transition tray 6 corresponding to the medicine bottle 22. The medication application window 13 is provided with sterile gloves. The sterile gloves are worn by the operator and extended into the isolation chamber 1 in an isolated manner relative to the internal space of the isolation chamber 1 to achieve sterile operation, so as to facilitate the transfer of the medicine bottle 22 on the transition tray 6 into the isolation cavity along the first inner isolation door, or the transfer of the medicine bottle 22 in the isolation cavity to the transition tray 6 along the first inner isolation door.

[0079] When the Chinese medicine granules in the medicine bottle 22 in any filling station 21 are used up, the medicine bottle 22 on the filling station 21 can be moved to the transition tray 6 near the medicine application window by the manipulator 4, and then the medicine bottle 22 on the transition tray 6 is manually transferred into the isolation cavity along the first inner isolation door through the medicine application operation window 13, and finally the medicine bottle 22 in the isolation cavity is taken out along the outer isolation door to add medicine.

Therefore, the medicine bottle 22 will not bring external pollutants into the isolation chamber 1 during the transfer between the inside and outside of the isolation chamber 1, and the purity of the internal environment of the isolation chamber 1 can be ensured when changing bottles and medicines.

[0080] In this embodiment, the dispensing system also includes a bag-making device 7 for forming medicine bags 9 from a roll of film 71 and placing the medicine bags 9 on a bag holder 32. The bag-making device 7 is used to make medicine bags 9 within the isolation chamber 1, reducing packaging costs and ensuring that the medicine bags 9 are clean and free of contamination. Specifically, the bag-making device 7 includes a back seal assembly, a bottom seal assembly, and a cutter assembly. After stretching and folding the roll of film 71, the back seal assembly and the bottom seal assembly sequentially complete the side and bottom edge sealing process of the packaging bag. The cutter assembly then cuts the roll of film 71, forming an independent medicine bag 9 and allowing the medicine bag 9 to fall onto the bag holder 32 below the bag-making device 7, completing the bag-making process.

[0081] Furthermore, the isolator 5 also includes a second inner isolation door connected to the isolation cavity, the second inner isolation door is arranged toward the bag-making device 7, and a film-applying operation window 14 is provided at a position of the isolation chamber 1 corresponding to the bag-making device 7.

Through the cooperation between the isolator 5 and the film-applying operation window 14, the film-applying operation of the bag-making device 7 can be completed in a sterile environment.

[0082] Furthermore, the medicine applying operation window 13 and the film applying operation window 14 both include a transparent panel and an operation port provided on the transparent panel. The edge of the wearing port of the sterile gloves is sealed on the operation port so that the inner layer of the sterile gloves is exposed outside the isolation chamber 1 and the outer layer of the sterile gloves is sealed inside the isolation chamber 1. The operator can reach into the isolation chamber 1 with the sterile gloves to apply medicine or film, and observe the internal situation of the isolation chamber 1 in real time through the transparent panel.

[0083] In this embodiment, the bag feeding mechanism 31 includes a chain 311 connected end to end and a chain drive assembly 312 for driving the chain 311 to move in a circulation manner, and the bag holder 32 is detachably mounted on the chain 311. Preferably, the bag feeding mechanism 31 includes a chain 311 and a chain drive assembly 312, the chain 311 is connected end to end to form a closed loop structure, the chain drive assembly 312 is used to drive the chain 311 to move in a circulation manner along the closed loop structure, and the bag holder 32 is detachably mounted on the chain 311; wherein, the chain drive assembly 312 includes a chain 311 driving gear engaged with the chain 311 and a chain 311 driving motor connected to the chain 311 driving gear and used to drive the chain 311 driving gear to rotate. The chain 311 driving motor drives the chain 311 driving gear to rotate, thereby driving the chain 311 to move. The driving structure is simple and efficient, and transmission accuracy is guaranteed.

[0084] In this embodiment, the bag feeding mechanism 31 drives the bag holder 32 to move via the chain 311. Since the chain 311 has stable transmission, can be disassembled and adjusted in length at will, and can be bent and changed in transmission direction at will, in actual application, a more complex movement trajectory of the bag holder 32 can be designed according to the requirements of the bag feeding line. Multiple bag holders 32 can be driven to different positions in sequence and stably, which facilitates docking with different filling stations 21 to realize the filling of multiple drugs, automatically and efficiently completing the conveying process of multiple packaging bags, and effectively improving the efficiency of drug dispensing.

[0085] Furthermore, any bag feeding channel is provided with multiple rows of filling stations 21, and the bag feeding mechanism 31 also includes multiple reversing wheels 313 respectively engaged with the chain 311. The multiple reversing wheels 313 are arranged at different positions of the chain 311 and respectively engaged with the chain 311. The chain 311 is subjected to multiple reciprocating changes through the multiple reversing wheels 313 to form multiple rows of bag feeding lines arranged in a serpentine shape, and the multiple rows of bag feeding lines are arranged one by one corresponding to the multiple rows of filling stations 21, so that the filling operations of multiple filling stations 21 can be completed simultaneously.

[0086] In this embodiment, a bag discharge device 8 is provided at the outlet end of the first channel 11 and the outlet end of the second channel 12, respectively. The bag discharge device 8 is used to seal the filled medicine bags 9 in the bag holder 32 and output the medicine bags 9 to the medicine discharge end of the dispensing system. The bag discharge device 8 is provided at the end of the bag feeding device 3 and is used to drive the bottom of the bag holder 32 to open and close, thereby driving the filled medicine bags 9 on the bag holder 32 to fall downward and enter the next process, automatically completing the bag discharge process, so that the bag holder 32 is automatically converted to an empty state before reaching the bag making device 7, so that the bag holder 32 can receive and support the next batch of medicine bags 9, thereby realizing a closed-loop automatic filling operation.

[0087] Furthermore, one or more bag discharge devices 8 are arranged on the first channel 11 path and / or the second channel 12 path, which are used to seal the medicine bags 9 that have completed filling before being transported to the outlet end of the bag channel and output the medicine bags 9 to the medicine discharge end of the dispensing system. Because multiple bag holders 32 are arranged along the bag channel, carrying multiple medicine bags 9 and running synchronously along the bag channel, each medicine bag 9 may have a different filling task. Therefore, when a bag holder 32 stops filling, the adjacent bag holder 32 also needs to stop synchronously. When the bag holders 32 are arranged at a high density, all bag holders 32 need to stop synchronously when passing each medicine bottle 22, which affects the filling efficiency. By arranging the bag discharge device 8 on the channel path, the medicine bags 9 that have completed the corresponding medicine filling in the channel path can be discharged in advance, sealed by the bag discharge device 8 arranged on the path and directly transported to the medicine discharge end, effectively improving the processing efficiency and reducing waiting time.
