Abstract
Description
Technical Field
[0001] This application relates to the field of automated drug dispensing technology, and in particular to a modular drug dispensing device and a drug dispensing method. Background Technology
[0002] In the current medical industry, medication preparation is mostly done manually by breaking ampoules and vials, mixing the liquid and powder medications, and then injecting the mixture into a medication bag. This method has many drawbacks. For example, the volume of liquid medication drawn manually can vary significantly, resulting in an inaccurate ratio of the mixed medication after powdering. Manually injecting the mixed medication into the medication bag further increases the deviation in the ratio. In addition, manual preparation is inefficient and prone to contamination.
[0003] To address the various drawbacks of manual medication dispensing, automated medication dispensing technology has gradually developed. In the field of automated medication dispensing technology, with the continuous development of the medical industry, the requirements for accuracy, efficiency, and safety in medication dispensing are increasing. Efficient and accurate medication dispensing technology can greatly improve the quality of medical services, reduce the interference of human factors in the medication dispensing process, and thus ensure the safety and effectiveness of patient medication. At the same time, the development of automated medication dispensing technology also helps improve hospital work efficiency and reduce the workload of medical staff.
[0004] However, current automated drug dispensing technology usually uses fixed production lines. A production line can only automate drug dispensing using one method. If the drug dispensing method needs to be changed, a new production line or the original production line needs to be redesigned. This results in insufficient flexibility, excessive investment, and is not conducive to practical production applications.
[0005] Therefore, how to overcome the shortcomings of existing technologies and solve the problem of insufficient flexibility in existing automated drug dispensing technologies is a problem to be solved in this technical field. Summary of the Invention

[0014] By adopting the above technical solution, the vial processing structure is modularized. In the medication dispensing method that requires vials, the first vial processing module can be directly selected.

The vial opening mechanism inside the module opens the vials and then transfers them to the vial station, which facilitates subsequent medication dispensing operations.
[0015] In some embodiments, the second medicine bottle processing module includes a module housing and a second medicine bottle storage, a bottle cutting mechanism, a bottle breaking mechanism, and a second medicine bottle robot disposed inside the module housing.

[0019] In some embodiments, the syringe processing module further includes a syringe destruction mechanism disposed inside the module housing, the syringe destruction mechanism being used to destroy used syringes.
[0020] By adopting the above technical solution, the used syringe can be destroyed and the needle removed, preventing the needle from being reused and contaminating the medicine.
[0021] In some embodiments, the module housing has a module outlet facing the dispensing tray on the side near the conveying device, and the bottom of the module housing has a plurality of wheels.
[0022] By adopting the above technical solution, the robotic arms in each module can move the medicine bags, medicine bottles, and syringes inside the module to the external medicine dispensing tray through the module outlet; the wheels at the bottom of the module shell can easily move each module to freely match the production line required for different medicine dispensing methods.
[0023] In some embodiments, a vibration mechanism is provided below the medicine bottle station, and clamping plates are provided on both sides above the medicine bottle station.

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0032] Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0033] Example 1 like Figure 1 As shown, for reference Figure 2 Embodiment 1 of this application provides a modular dispensing device, including a conveying device 1 and multiple dispensing trays 2 disposed on the conveying device 1. The conveying device 1 is in the form of a linear conveyor belt, which can employ a double-speed chain design; see reference... Figure 4As shown, the dispensing tray 2 is equipped with a liquid bag station 201 and multiple medicine bottle stations 202. The liquid bag station 201 is used to place liquid bags, and the multiple medicine bottle stations 202 are used to place ampoules and vials respectively. It should be noted that the dispensing steps differ for different drug components. Commonly used dispensing materials include mother liquor, drug powder, and drug solution. Drug powder is generally stored in vials, drug solution is generally stored in ampoules, and mother liquor is stored in liquid bags. The dispensing steps differ for different drug components; for example, the drug solution can be directly injected into the mother liquor, or the drug powder and drug solution can be mixed and shaken well before being injected into the mother liquor. To enhance the flexibility of the production line, multiple working modules are arranged on one side of the conveying device 1. These modules are spliced together along the moving direction of the dispensing tray 2, with the outlet of each module facing the dispensing tray 2. Each working module includes one or more of the following: a liquid bag processing module 3, a first medicine bottle processing module 4, a second medicine bottle processing module 5, and a syringe processing module 6. Any number of modules can be selected as needed, and one or more of the same module can be selected as required. Specifically, the liquid bag processing module 3 processes the liquid bags and transfers them to the liquid bag station 201; the first medicine bottle processing module 4 and the second medicine bottle processing module 5 process the medicine bottles and transfer them to the medicine bottle station 202; and the syringe processing module 6 processes the syringes and transfers the liquid from the medicine bottle into the liquid bag using the syringe.
[0034] The above technical solution modularizes the processing structure of liquid bags, medicine bottles, and syringes. By splicing the modules, it can adapt to the needs of different drug dispensing methods, enabling the same production line to perform drug dispensing operations for multiple methods, improving the flexibility of the production line, reducing investment under the needs of multiple drug dispensing methods, and facilitating practical production applications.
[0035] refer to Figure 3 As shown, in some embodiments, the module housing 10 has a module outlet 20 facing the dispensing tray 2 on the side near the conveying device 1, and the bottom of the module housing 10 is provided with several wheels 30, which have a locking function. Based on the above configuration, the medicine bags, medicine bottles, and syringes inside the module can be moved to the external dispensing tray 2 through the module outlet 20; the wheels 30 at the bottom of the module housing 10 can easily move each module to freely match the production line required for different dispensing methods.
[0036] refer to Figure 5As shown, in some embodiments, the liquid bag processing module 3 includes a module housing 10 and a liquid bag storage tank 301 and a liquid bag robot 302 disposed inside the module housing 10. The liquid bag robot 302 is used to retrieve liquid bags from the liquid bag storage tank 301 and transfer the liquid bags to the liquid bag station 201 on the external dispensing tray 2. The liquid bag storage tank 301 is used to store liquid bags containing mother liquor. The specific design of the liquid bag storage tank 301 can refer to the design of existing automated dispensing containers, allowing the liquid bags to be automatically transported to the side near the liquid bag robot 302, thus enabling the liquid bag robot 302 to easily transfer the liquid bags. The liquid bag robot 302 can be a gripping robot or a suction robot, as long as it can transfer liquid bags. Furthermore, the liquid bag processing module 3 also includes a liquid bag labeling machine 303 disposed inside the module housing 10. The liquid bag labeling machine 303 is used to label the liquid bags, indicating the drug components. The liquid bag labeling machine 303 can be any suitable labeling machine available on the market. The liquid bag robot 302 is also used to transfer the liquid bags to the liquid bag labeling machine 303 for labeling, and then transfer the liquid bags to the liquid bag station 201 on the external dispensing tray 2. Through the above scheme, the liquid bag processing structure is modularized. In dispensing methods that require the use of liquid bags, the liquid bag processing module 3 can be directly selected. The liquid bag robot 302 inside the module can transfer the liquid bags in the liquid bag storage 301 and transfer them to the liquid bag station 201, facilitating subsequent dispensing operations.
[0037] refer to Figure 6As shown, in some embodiments, the first medicine bottle processing module 4 includes a module housing 10 and a first medicine bottle storage 401, a capping mechanism 402, and a first medicine bottle robot 402 disposed inside the module housing 10. The first medicine bottle robot 402 is used to pick up medicine bottles from the first medicine bottle storage 401 and transfer them to the capping mechanism 402 for capping, and then transfer the medicine bottles to the medicine bottle station 202 on the external dispensing tray 2. The first medicine bottle storage 401 is used to store vials containing powdered medicine. The design of the first medicine bottle storage 401 can refer to the existing automated dispensing container design, allowing the vials to be automatically transported to the side close to the first medicine bottle robot 402, so that the first medicine bottle robot 402 can easily transfer the vials. The first medicine bottle robot 402 can be a gripping robot or a suction robot, as long as it can transfer vials. The capping mechanism 402 is used to open the vials transferred by the robotic arm, and an existing structure for opening vials can be selected. Through the above technical solution, the vial processing structure is modularized. In medication dispensing methods that require vials, the first vial processing module 4 can be directly selected. The first vial robotic arm 402 inside the module transfers the vials from the first vial storage 401, the capping mechanism 402 inside the module opens the vials, and then the vials are transferred to the vial station 202 for convenient subsequent medication dispensing operations.
[0038] refer to Figure 7As shown, in some embodiments, the second medicine bottle processing module 5 includes a module housing 10 and a second medicine bottle storage 501, a bottle cutting mechanism 502, a bottle breaking mechanism 503, and a second medicine bottle robot 504 disposed inside the module housing 10. The second medicine bottle robot 504 is used to pick up medicine bottles from the second medicine bottle storage 501 and transfer them to the bottle cutting mechanism 502 and the bottle breaking mechanism 503 for bottle cutting and breaking operations, and then transfer the medicine bottles to the medicine bottle station 202 on the external dispensing tray 2. The second medicine bottle storage 501 is used to store ampoules containing liquid medicine. The design of the second medicine bottle storage 501 can refer to the existing automated dispensing container design, so that the ampoules can be automatically transported to the side close to the second medicine bottle robot 504, thereby allowing the second medicine bottle robot 504 to easily transfer the ampoules. The second medicine bottle robot 504 can be a gripping robot or a suction robot, as long as it can transfer ampoules. The bottle-cutting mechanism 502 is used to cut the ampoules transferred by the robotic arm; the bottle-breaking mechanism 503 is used to break the cut ampoules transferred by the robotic arm. The bottle-cutting mechanism 502 and the bottle-breaking mechanism 503 can adopt existing structural designs for cutting and breaking ampoules. By modularizing the ampoule processing structure, in medication dispensing methods that require the use of ampoules, the second medication bottle processing module 5 can be directly selected. The second medication bottle robotic arm 504 inside the module transfers the ampoules from the second medication bottle storage 501, and the bottle-cutting mechanism 502 and the bottle-breaking mechanism 503 inside the module cut and break the ampoules, and then transfer the ampoules to the medication bottle station 202 for convenient subsequent medication dispensing operations.
[0039] In some embodiments, the first bottle processing module 4 and the second bottle processing module 5 can also be combined into one bottle processing module. In this case, the first bottle storage 401 and the second bottle storage 501 are located in the same module housing 10. The bottle processing mechanism in the module housing 10 includes a cap opening mechanism 402, a bottle cutting mechanism 502, and a bottle breaking mechanism 503. In addition, only one robotic arm can be set in the module housing 10 to operate ampoules and vials. Of course, two or more robotic arms can also be set to operate ampoules and vials respectively.
[0040] refer to Figure 8As shown, in some embodiments, the syringe processing module 6 includes a module housing 10 and a syringe magazine 601 and a syringe robot 602 disposed inside the module housing 10. The syringe robot 602 is used to retrieve syringes from the syringe magazine 601 and transfer the liquid medicine in the vial into a liquid bag using the syringes. The syringe magazine 601 is used to store disposable syringes. The design of the syringe magazine 601 can refer to existing automated dispensing container designs or automated transport device designs, allowing the syringes to be automatically transported to the side near the syringe robot 602, thus enabling the syringe robot 602 to easily transfer the syringes. In addition to transferring syringes, the syringe robot 602 also needs to have the function of pushing and pulling the syringe head; therefore, a suction robot with corresponding functions needs to be selected. Furthermore, the syringe processing module 6 also includes a syringe destruction mechanism 603 disposed inside the module housing 10. This mechanism 603 destroys the used syringes, removing the needle tip to prevent contamination of the medication due to needle tip reuse. The syringe destruction mechanism 603 can utilize existing syringe needle processing devices. Through this technical solution, the syringe processing structure is modularized. When syringes are needed, the syringe processing module 6 is directly selected. The syringe manipulator 602 inside the module transfers the syringes, drawing medication from ampoules into vials, and then drawing the mixture of medication and powder from the vials into a liquid bag, completing the medication preparation. After preparation, the vials, ampoules, and liquid bags can be manually collected at the discharge port.
[0041] refer to Figure 9As shown, in some embodiments, a vibration mechanism 203 is provided below the medicine bottle station 202, and clamping plates 204 are provided on both sides above the medicine bottle station 202. The clamping and fixing of the medicine bottle is accomplished by the clamping plates 204. The vibration mechanism 203 is connected to the clamping plates 204 through a transmission component. The medicine bottle station 202 can be fixed to the dispensing tray 2 by connecting posts on both sides. The diameter of the through hole on the medicine bottle station 202 for inserting the medicine bottle needs to be larger than the diameter of the medicine bottle to prevent damage to the medicine bottle from hitting the inner wall of the through hole when the vibration mechanism 203 drives the clamping plates 204 and thus the medicine bottle to vibrate. A buffer layer, such as sponge, can also be provided on the inner wall of the through hole to enhance safety. Furthermore, the clamping plates 204 are fixed to the transmission component, which is slidably mounted on the output end of the vibration mechanism 203. This sliding is configured to only move in the direction in which the two clamping plates 204 face each other; other directions are limited and cannot be moved. Therefore, the two clamping plates 204 can move closer and then further apart, but will not rotate or detach from the output end of the vibration mechanism 203. The vibration mechanism 203 can utilize the structural design of existing vibration devices. It should be noted that the vibration direction of the vibration mechanism 203 is preferably up-and-down vibration, vibration parallel to the length direction of the clamping plate 204, or a combination of both. Vibration parallel to the width direction of the clamping plate 204 is avoided to prevent interference between multiple clamping plates 204. Furthermore, the transmission component of the clamping plate 204 is slidably mounted on the output end of the vibration mechanism 203. This sliding range is controllable by a limiting component, which can be a stop block mounted on the output end of the vibration mechanism 203. This limits the sliding range of the transmission component, preventing the clamping plate 204 from exceeding the preset range due to vibration. For example, it prevents the clamping plate 204 from detaching from the end of the vibration mechanism 203, or prevents interference between multiple clamping plates 204. With the above configuration, the clamping plate 204 can hold the medicine bottle. The vibration mechanism 203 drives the clamping plate 204, which in turn drives the medicine bottle to vibrate, ensuring uniform mixing of the liquid and powder medicine within the bottle and accelerating the dissolution rate of the powder in the liquid medicine.
[0042] refer to Figure 10As shown, in some embodiments, the clamping plates 204 on both sides are provided with arc-shaped grooves 205 that match the curvature of the medicine bottle on the side facing each other, and the top of the arc-shaped grooves 205 is provided with arc-shaped sliding grooves 206 whose diameter gradually increases upward; the clamping plates 204 on both sides are connected by elastic members 207, and when the elastic members 207 are in their natural state, the distance between the arc-shaped grooves 205 on both sides is less than the diameter of the medicine bottle. Here, the distance between the arc-shaped grooves 205 on both sides refers to the distance between the farthest axes of the two arc-shaped grooves 205. Through the above scheme, the arc-shaped grooves 205 can match the shape of the medicine bottle for easy clamping, the elastic members 207 can give the clamping plates 204 their own clamping force for the medicine bottle without the need for additional clamping drive components, and the arc-shaped sliding grooves 206 can facilitate the robot arm to insert the medicine bottle between the clamping plates 204 from the arc-shaped sliding grooves 206, so that the clamping plates 204 can complete the clamping of the medicine bottle through the rebound force of the elastic members 207. The elastic element 207 can be a spring with strong elasticity and is set at both ends of the clamping plate 204. Alternatively, springs can be set on the opposite surfaces of the two clamping plates 204 to connect them.
[0043] Example 2 Based on the modular dispensing equipment provided in Embodiment 1, Embodiment 2 provides a dispensing method applied to the modular dispensing equipment described in the first aspect. The dispensing method includes the following steps.
[0044] Step 101: Select one or more of the following modules according to medication needs: liquid bag processing module 3, first vial processing module 4, second vial processing module 5, and syringe processing module 6. For example, if only liquid bags and ampoules are needed, select liquid bag processing module 3, second vial processing module 5, and syringe processing module 6 and connect them together; if liquid bags, vials, and ampoules are needed, connect liquid bag processing module 3, first vial processing module 4, second vial processing module 5, and syringe processing module 6 together.
[0045] Step 102: Move the selected modules to one side of the conveyor device 1 and assemble them. After moving each module to one side of the conveyor device 1, lock the wheels 30 of each module.
[0046] Step 103: Through the cooperation of various modules, the medication is dispensed on the dispensing tray 2. Specifically, when the dispensing tray 2 reaches the liquid bag processing module 3, the liquid bag robot 302 takes out the corresponding mother liquor liquid bag from the liquid bag storage 301, transfers the liquid bag to the liquid bag marking machine 303, marks the dispensing information onto the liquid bag, and then transfers the liquid bag to the liquid bag station 201. When the dispensing tray 2 reaches the first bottle processing module 4 and the second bottle processing module 5 (these two modules can be separate or a single integrated bottle processing module; the following explanation uses one module as an example), one robot takes out the corresponding powder vial from the first bottle storage 401 to a bottle station 202, and the other robot takes out the corresponding liquid ampoule from the second bottle storage 501 to another bottle station 202. When the medication tray 2 reaches the syringe processing module 6, the syringe robot 602 retrieves a disposable syringe from the syringe magazine 601, then transports it above the broken ampoule, drawing the medication from the ampoule into the opened vial. After the vibration mechanism 203 mixes the powder and liquid medication in the vial evenly, the syringe robot 602 controls the syringe to draw out the mixed medication and inject it into the liquid bag placed on the liquid bag station 201. The syringe robot 602 then transports the syringe to the syringe destroying mechanism 603. The entire process is connected in series by a linear conveyor belt driving the medication tray 2. Finally, the used vials and ampoules are manually collected from the discharge port, and the liquid bag containing the mixed medication is also manually discharged from the discharge port.
[0047] By adopting the above technical solution, the processing structure of liquid bags, medicine bottles, and syringes is modularly designed. By splicing the modules, it can adapt to the needs of different drug dispensing methods, enabling the same production line to perform drug dispensing operations for multiple methods, improving the flexibility of the production line, reducing investment under the needs of multiple drug dispensing methods, and facilitating practical production applications.
[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
