[0020] In FIG. 1, "FE" means the first end portion, and "SE" means the second end portion.

[0021] As shown in FIG. 1, the drug delivery system provided by the embodiment of the present invention includes a first conveyor belt device 1, a second conveyor belt device 2, and a first cage moving device 4. The first and second conveyor belt devices can convey the drug cages thereon or hold the drug cages in a stationary state. The conveying direction of the first conveyor belt device 1 is the first direction, the conveying direction of the second conveyor belt device 2 is the second direction, and the first and second directions are opposite. The first cage moving device 4 can move the drug cages between the first and second conveyor belt devices. Here, both the first conveyor belt device 1 and the second conveyor belt device 2 can convey the drug cages along their conveying directions. In order to improve the working efficiency, at the same moment, a plurality of drug cages can be placed on each of the first conveyor belt device 1 and the second conveyor belt device 2, some of the drug cages can be conveyed, and the other drug cages can be in a stationary state.

[0022] As shown in FIG. 1, this first conveyor belt device 1 can convey the medicine cage along the first direction (i.e., the solid arrow in FIG. 1), that is, it can convey from the first end to the second end. This second conveyor belt device 2 can convey the medicine cage along the second direction (i.e., the dotted arrow in FIG. 1), that is, it can convey from the second end to the first end. Here, in the first direction, the first position is in front of the second position. Therefore, in the first conveyor belt device 1, the medicine cage can be conveyed from the first position to the second position. Then, the first cage moving device 4 moves the medicine cage at the second position of the first conveyor belt device 1 to the second position on the second conveyor belt device. Then, the second conveyor belt device 2 can convey this medicine cage to the first position. As described above, based on the first conveyor belt device 1, the second conveyor belt device 2, and the first cage moving device 4, this medicine cage can be moved in both directions.

[0023] Here, each of the first conveyor belt device 1 and the second conveyor belt device 2 can be formed by connecting a plurality of transmission belts in series. The plurality of first cage moving devices 4 are distributed along the extending direction of the first conveyor belt device 1 and the second conveyor belt device, and the positions of the respective first cage moving devices 41 are fixed. Further, an orbit may be provided. This orbit is arranged parallel and opposite to the first and second conveyor belt devices. The first cage moving device 4 can move along this orbit. At this time, there are also a plurality of first cage moving devices 4. Here, the first cage moving device 4 may be a robot hand. This robot hand can grasp one medicine cage from a certain conveyor belt device and place it on another transmission belt device. It may also be a conveyor belt, a lifting device, etc. (for example, one of the first and second conveyor belt devices is arranged above the other, and this lifting device can convey the medicine cage between the first and second conveyor belt devices).

[0024] A plurality of medicine outlets are provided above the first conveyor belt device 1. The plurality of medicine outlets are the first conveyor When the medicine cages on the first conveyor belt device are distributed along the conveying direction of the belt device 1 and are located below any of the medicine outlets, the medicine discharged from the medicine outlet can be received. Here, in the medicine warehouse, a plurality of medicine storage shelves are provided, a plurality of medicines are stored on each medicine storage shelf, one medicine outlet is provided for each medicine storage shelf, and the medicine stored on the medicine storage shelf is discharged from this medicine outlet.

[0025] Further including a control device, when the control device receives the first prescription to be processed, it acquires M medicine outlets corresponding to the first prescription to be processed. Along the direction, the M medicine outlets are sequentially the first medicine outlet, the second medicine outlet,..., the Mth medicine outlet. Then, it controls the first conveyor belt device 1 to pass an empty first medicine cage through the first medicine outlet to the Mth medicine outlet in sequence to receive medicine. Next, it controls the first cage moving device 4 to move the first medicine cage to the second conveyor belt device 2, controls the second conveyor belt device 2 to convey the first medicine cage along the second direction. Then, it controls the first cage moving device 4 to move the first medicine cage to the first conveyor belt device 1, positions the first medicine cage in front of the first medicine outlet along the first direction. Next, it controls the first conveyor belt device 1 to pass the first medicine cage through the first medicine outlet to the (I - 1)th medicine outlet in sequence to receive medicine. Both M and I are natural numbers, 1 side and 1 ≤ I ≤ M. 2 ≦I≦Mである。

[0026] Here, in the first direction, the front refers to the direction of the tail of the solid arrow in FIG. 1, and the rear refers to the direction of the head of the solid arrow in FIG. 1. In the second direction, the front refers to the direction of the tail of the dotted arrow in FIG. 1, and the rear refers to the direction of the head of the dotted arrow in FIG. 1.

[0027] Here, in actual use, each pharmacy is equipped with a pharmacy management system, which stores the drug information in each drug storage shelf (including at least information such as the drug type, storage quantity, and storage location of all drugs stored in each drug storage shelf). Usually, a plurality of drug dispensing windows are provided in this pharmacy, and workers are on duty at each window. The worker receives a prescription (for example, the patient hands the prescription receipt to the worker or the system automatically distributes it). The prescription contains a plurality of drug types and the corresponding quantities for each drug type. When the worker inputs the prescription information into the pharmacy management system (for example, enters the prescription number or reads the prescription number with a card reader placed at the drug dispensing window), the pharmacy management system obtains information such as the plurality of drug types contained in the prescription and the corresponding quantities for each drug type. Then, after processing with a preset algorithm, it obtains information such as from which drug storage shelf to take the drugs, the drug types of the plurality of drugs that need to be discharged from each drug storage shelf, and the corresponding quantities for each drug. Next, it only needs to discharge the relevant drugs from the corresponding drug outlet. Therefore, along the first direction, the M drug outlets are denoted as the first drug outlet, the second drug outlet,..., the Mth drug outlet. The drug cage passes through the M drug outlets and receives drugs from each drug outlet. The drug cage filled with drugs is transported to the drug dispensing window, and the worker takes out the drugs from the drug cage, packages them, and hands them to the patient.

[0028] Here, when all the medicine cages strictly pass through the first medicine outlet first, then the second medicine outlet, and so on, and finally the Mth medicine outlet, if a certain medicine outlet (for example, the (I - 1)th medicine outlet) is congested, all the medicine cages that need to pass through this medicine outlet need to wait for a certain period of time, and it is understood that the efficiency of the medicine conveying system will be greatly reduced. At this time, first convey one medicine cage to a certain medicine outlet (for example, the Ith medicine outlet) behind the (I - 1)th medicine outlet, then sequentially perform the medicine discharging operations of the subsequent medicine outlets (pass through them in order from the Ith medicine outlet to the Mth medicine outlet), and then use the second conveyor belt device 2 to convey the medicine cage (the medicine discharging operations of the medicine cage from the Ith medicine outlet to the Mth medicine outlet have been completed) to a position in front of the first medicine outlet, and then complete the medicine discharging operations from the first medicine outlet to the (I - 1)th medicine outlet. In this way, the efficiency of the medicine conveying system is greatly improved, with high orderliness and low error probability.

[0029] Optionally, when the medicine cage filled with medicine is conveyed to the medicine distribution window, for example, it may prompt the operator or patient to obtain the medicine by means of voice broadcast or display of prescription - related information on a display device.

[0030] Here, a plurality of detectors are arranged on each of the first conveyor belt device 1 and the second conveyor belt device 2, and each medicine cage is provided with a storage device for storing the unique identification code of the medicine cage. When the medicine cage passes through these detectors, the detectors can read the unique identification code from the storage device, accurately identify the medicine cage, and also obtain information such as the location of the medicine cage. At the same time, the correspondence relationship between the unique identification code and the prescription can also be constructed. For example, the detector may be a two - dimensional code scanning device. Print a two - dimensional code on the outer surface of the medicine cage, and the unique identification code of the medicine cage is stored in this two - dimensional code. The detector may also be an NFC (Near Field Communication, near - field wireless communication) reading device. An NFC communication device is provided on the medicine cage, and the unique identification code of the medicine cage is stored in this NFC communication device.

[0031] Here, as shown in FIG. 1, the conveying directions of the first and second conveying belt devices do not have to be straight lines.

[0032] In this embodiment, each of the first conveying belt device 1 and the second conveying belt device 2 has a first end portion and a second end portion provided opposite to each other. The first direction is from the first end portion to the second end portion, the second direction is from the second end portion to the first end portion, and a dispensing window is provided at the second end portion of the first conveying belt device 1. When the control device determines that the first prescription sheet to be processed contains the drug dispensed, it controls the first conveying belt device to pass the first drug cage through the Mth drug outlet to receive the drug, and then conveys the first drug cage to the dispensing window. Then, when it is detected that the first drug cage is arranged at the second end portion of the second conveying belt device, it controls the second conveying belt device to convey the first drug cage, controls the first cage moving device to move the first drug cage to the first conveying belt device, and positions the first drug cage in front of or at the same position as the first drug outlet along the first direction. Next, it controls the first drug cage to sequentially pass the first drug cage from the first drug outlet to the (I - 1)th drug outlet to receive the drug.

[0033] Here, optionally, the first end portion of the first conveying belt device 1 and the first end portion of the second conveying belt device 2 are located at the same position, and the second end portion of the first conveying belt device 1 and the second end portion of the second conveying belt device 2 are located at the same position.

[0034] Here, pharmacy compounding generally refers in a broad sense to prescription compounding (compounding based on a prescription), non-prescription compounding (compounding not based on a prescription, for example, over-the-counter drugs are sold at community pharmacies), and pharmaceutical technology services such as pharmaceutical information services included therein. Generally, it includes processes such as receiving a prescription, examining a prescription, formulating a prescription (including different contents such as obtaining drugs, secondary packaging, creating temporary prescriptions, etc.), packaging, checking, distributing drugs, and guiding the use of drugs. Narrowly, pharmacy compounding refers to the operation of "dispensing a drug specially prepared for a patient based on a doctor's prescription, with instructions on usage and dosage." Broadly, it is understood as an operation unit of pharmacy compounding, such as preparing a temporary prescription (for hospital drugs against fixed prescriptions) in the step of formulating a prescription. As described above, drugs that require compounding are the above-mentioned compounded drugs.

[0035] Here, compounded drugs often need to be processed manually by a doctor. In this case, the first conveyor belt device 1 conveys the first drug cage to the dispensing window. The doctor takes the first drug cage, puts the compounded drug into the first drug cage, and then places the first drug cage on the second end of the second conveyor belt device 2. Then, the second conveyor belt device 2 conveys the first drug cage in the direction of the first end. Finally, the first cage moving device 4 moves the first drug cage to the first conveyor belt device 1, and along the conveying direction of the first conveyor belt device 1, the position of the first drug cage is in front of or at the same position as the first drug outlet. Here, a sensor is provided at the second end of the second conveyor belt device 2, and this sensor can detect whether the first drug cage is placed at the second end. Similarly, a sensor is provided at the second end of the first conveyor belt device 1, and this sensor can detect whether the first drug cage is conveyed to the second end. Furthermore, a prompting device is provided at the second end of the first conveyor belt device 1. When it detects that the first drug cage is conveyed to the second end, this prompting device presents relevant information about the compounded drug via voice or a display screen.

[0036] Here, a sensor is provided at the second end of the second conveyor belt device 2, and this sensor can detect whether the first drug cage is placed at the second end. Similarly, a sensor is provided at the second end of the first conveyor belt device 1, and this sensor can detect whether the first drug cage is conveyed to the second end. Furthermore, a prompting device is provided at the second end of the first conveyor belt device 1. When it detects that the first drug cage is conveyed to the second end, this prompting device presents relevant information about the compounded drug via voice or a display screen.

[0037] In this embodiment, there are a plurality of the first cage moving devices 4, which are distributed along the extending direction of the first and second conveyor belt devices. Along the first direction, at least one first cage moving device 4 is located in front of or at the same position as the frontmost chemical outlet, and at least one first cage moving device 4 is located behind or at the same position as the rearmost chemical outlet. "Controlling the first cage moving device 4 to move the first chemical cage to the second conveyor belt device 2" specifically includes controlling the first conveyor belt device 1 to move the first chemical cage to the position of the first cage moving device, and then controlling the first cage moving device to move the first chemical cage to the second conveyor belt device 2. In the first direction, the first cage moving device is located behind or at the same position as the Mth chemical outlet. Here, after the first chemical cage receives the chemical discharged from the Mth chemical outlet, the first chemical cage is continuously conveyed backward until it reaches the cage retraction position, or after the first chemical cage receives the chemical discharged from the Mth chemical outlet, the first chemical cage is not continuously conveyed backward, and the position at this time is the cage retraction position.

[0038] "Controlling the first cage moving device 4 to move the first chemical cage to the first conveyor belt device 1, and along the first direction, the position of the first chemical cage is located in front of the first chemical outlet" specifically includes controlling the second conveyor belt device 2 to move the first chemical cage to the position of the second cage moving device, and then controlling the second cage moving device to move the first chemical cage to the first conveyor belt device 1. In the first direction, the second conveyor belt device is located in front of or at the same position as the first chemical outlet.

[0039] Optionally, the first cage moving device 4 may be a vertical lifting device. The first and second conveyor belt devices are formed by connecting a plurality of conveyor belts in series, and a steering device is arranged at the connection part of two conveyor belts. The height of the first conveyor belt device 1 is higher than that of the second conveyor belt device 2. The top end of this vertical lifting device is connected to the first conveyor belt device 1, and the bottom end is connected to the second conveyor belt device 2. For the convenience of description, it is assumed that two adjacent conveyor belts, namely the first and second conveyor belts, are provided on each of the first and second conveyor belt devices, and both ends of the steering device are respectively connected to the first conveyor belt and the second conveyor belt. This steering device specifically has the following functions. (1) Receive the medicine cage conveyed from the first conveyor belt, and then the steering device can convey the medicine cage to the second conveyor belt. (2) Receive the medicine cage conveyed from the second conveyor belt, and then the steering device can convey the medicine cage to the first conveyor belt. (3) In the first conveyor belt device 1, the steering device receives the medicine cage conveyed from the first conveyor belt or the second conveyor belt. Then, after the steering device conveys the medicine cage to the vertical lifting device, this lifting device moves downward, and conveys the medicine cage to the steering device in the second conveyor belt device 2. Then, the operation of moving the cage from the first conveyor belt device 1 to the second conveyor belt device 2 can be completed. (4) In the second conveyor belt device 2, the steering device receives the medicine cage conveyed from the first conveyor belt or the second conveyor belt. Then, after the steering device conveys the medicine cage to the vertical lifting device, this lifting device moves upward and conveys the medicine cage to the steering device in the first conveyor belt device 1. Then, the operation of moving the cage from the second conveyor belt device 2 to the first conveyor belt device 1 can be completed.

[0040] In this embodiment, a plurality of empty cage storage devices distributed along the extending direction of the first conveyor belt device 1 further includes a storage device 5 for empty cages. Along the first direction, at least one storage device 5 for empty cages is located in front of or at the same position as the frontmost medicine outlet. The operation of "controlling the first conveyor belt device 1 to pass an empty first medicine cage from the first medicine outlet to the Mth medicine outlet to receive medicine" specifically includes taking out an empty first medicine cage from the first storage device for empty cages, placing the first medicine cage on the first conveyor belt device 1, controlling the first conveyor belt device 1 to sequentially pass the first medicine cage from the first medicine outlet to the Mth medicine outlet to receive medicine, and the first storage device for empty cages is located in front of or at the same position as the first medicine outlet. Here, at each medicine distribution window, after the operator packages the medicine in the medicine cage and delivers it to the patient, the empty cage is placed in the storage device 5 for empty cages.

[0041] In this embodiment, it further includes a plurality of third conveyor belt devices 3. One end of the third conveyor belt device 3 is connected to the first conveyor belt device 1, and the other end is connected to the medicine distribution window. The medicine cage in the first conveyor belt device 1 can move into the third conveyor belt device 3. The control device is further used to obtain the third conveyor belt device 3 corresponding to the first prescription to be processed when receiving the first prescription to be processed. In the first direction, the connection part of the corresponding third conveyor belt device 3 and the first conveyor belt device 1 is located behind or at the same position as the (I - 1)th medicine outlet. The operation of "controlling the first conveyor belt device 1 to pass an empty first medicine cage from the first medicine outlet to the Mth medicine outlet in sequence to receive medicine" specifically includes controlling the first conveyor belt device 1 to pass an empty first medicine cage from the first medicine outlet to the Mth medicine outlet to receive medicine, controlling the first medicine cage to move continuously, moving the first medicine cage to the third conveyor belt device 3 corresponding to the first prescription to be processed, and then controlling the corresponding third conveyor belt device 3 to move the first medicine cage to the medicine distribution window.

[0042] Here, in reality, when an operator sits beside the medicine distribution window and a medicine cage filled with medicine is transported to the medicine distribution window by the third conveyor belt device 3, the operator takes the medicine cage, packages the medicine inside, and distributes it to patients. Therefore, it is necessary that the connection part between the corresponding third conveyor belt device 3 and the first conveyor belt device 1 is behind or at the same position as the first-I medicine outlet.

[0043] In this embodiment, it further includes a second cage moving device provided at the connection part between the third conveyor belt device 3 and the first conveyor belt device 1. The "moving the first medicine cage to the third conveyor belt device 3 corresponding to the first prescription to be processed" specifically includes controlling the second cage moving device to move the first medicine cage to the third conveyor belt device 3 corresponding to the first prescription to be processed. Here, this second cage moving device may be a robot hand or the like.
