Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a powder dispensing system with a dual-chamber bag for dispensing powder and liquid. Background Art

[0002] Dual-chamber bag infusion formulations are based on ordinary plastic infusion bags, but are divided into two independent, sealed chambers using weak welding technology. Each chamber contains a different medication. Before use, pressing the chamber connects the two chambers, allowing for mixing and infusion into a ready-to-use infusion preparation system. The initial purpose of developing dual-chamber bag formulations was to avoid secondary contamination during clinical infusion preparation in emergency and unconventional situations, and to facilitate clinical medication use. Based on the state of the medication in the chambers, they are generally divided into two types: liquid-liquid dual-chamber bags and powder-liquid dual-chamber bags. However, current technology for dispensing powder-liquid dual-chamber bags is imperfect, with slow dispensing speeds that cannot meet production capacity requirements. Current equipment speeds are approximately 1000 bags / hour, dispensing accuracy is low, particle control is poor, sterility is compromised, and weighing is manual, preventing online weighing.

[0003] Therefore, how to provide a powder dispensing system with a dual-chamber bag to at least partially solve the above-mentioned drawbacks is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0012] Preferably, a cleaning mechanism is provided between the bag-upper mechanism and the bag-cutting mechanism, and at the bag-downper mechanism.

[0013] As a preferred option, the cleaning method of the cleaning mechanism is ion air cleaning.

[0014] Preferably, the dispensing mechanism uses screw dispensing. The dispensing mechanism includes a barrel, a powder feeding channel, and a dispensing section. The barrel and the dispensing section are connected through the powder feeding channel. A powder feeding screw is installed in the powder feeding channel. The powder feeding screw conveys the powder in the barrel to the dispensing section by rotating. The dispensing section is used to dispense the powder into a powder-liquid dual-chamber bag.

[0015] As a preferred option, the specific dispensing method of the dispensing mechanism is airflow dispensing.

[0016] Preferably, an online weighing structure is provided between the dispensing mechanism and the bag cutting structure. The weighing structure is used to sample and check the weight of the powder dispensed by the dispensing mechanism.

[0018] Preferably, the annular conveying mechanism includes a powder-liquid dual-chamber bag clamp, which is capable of opening or closing the bag opening of the powder-liquid dual-chamber bag as it moves to the bag opening mechanism, dispensing mechanism, and inflation mechanism.

[0019] Preferably, the inflation mechanism and the sealing mechanism are located in a nitrogen-filled cavity.

[0020] Compared to the aforementioned background technology, the present invention provides a powder dispensing system for a dual-chamber bag containing powder and liquid, comprising: a frame, wherein a closed-type restricted-entry isolation system and an open-type restricted-entry isolation system are spaced apart on the frame; a ring conveying mechanism, rotatably mounted on the frame for transporting the dual-chamber bag containing powder and liquid, wherein the conveying direction of the ring conveying mechanism is parallel to the length extension direction of the frame; and a bag upper detection component, a bag cutting mechanism, a weighing mechanism, a bag opening mechanism, a dispensing mechanism, an inflation mechanism, a sealing mechanism, and a bag lowering mechanism arranged sequentially along the conveying direction of the ring conveying mechanism; wherein the bag cutting mechanism, the weighing mechanism, the bag opening mechanism, the dispensing mechanism, the inflation mechanism, and the sealing mechanism are located in the closed-type restricted-entry isolation system, and the remaining structures are located in the open-type restricted-entry isolation system.

DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0030] The purpose of this invention is to provide a powder dispensing system with a dual-chamber bag, which can improve the dispensing method, increase dispensing speed, accuracy and efficiency, and also ensure a sterile dispensing environment.

[0031] To achieve the above objectives, the present invention provides the following technical solution:

[0032] Please see Figure 1 and Figure 2 This embodiment provides a powder dispensing system for a dual-chamber bag containing powder and liquid, comprising: a frame 01, on which a closed-type restricted-entry isolation system 02 and an open-type restricted-entry isolation system 03 are spaced apart; an annular conveying mechanism 04, rotatably mounted on the frame 01, for transporting the dual-chamber bag containing powder and liquid, the conveying direction of the annular conveying mechanism 04 being parallel to the length extension direction of the frame 01; and sequentially arranged along the conveying direction of the annular conveying mechanism 04 are an upper bag detection component, a bag cutting mechanism 05, a weighing mechanism 13, a bag opening mechanism 14, a dispensing mechanism 06, a filling mechanism 07, a sealing mechanism 08, and a lower bag mechanism 09; the bag cutting mechanism 05, the weighing mechanism 13, the bag opening mechanism 14, the dispensing mechanism 06, the filling mechanism 07, and the sealing mechanism 08 are located in the closed-type restricted-entry isolation system 02, while the remaining structures are located in the open-type restricted-entry isolation system 03.

[0033] In this embodiment, the annular conveying mechanism 04 specifically comprises a motor and a sprocket. The motor is located at both ends of the frame 01, with its output shaft pointing vertically upwards. Gears are located at the ends of the output shaft, and the sprockets are mounted on the gears at both ends. Powder-liquid dual-chamber bag clamps are evenly spaced on the sprockets, with four clamps forming a group. In this embodiment, the powder-liquid dual-chamber bag clamps provide powder-liquid dual-chamber bags for each process, enabling the opening and clamping of the powder chamber bag, reducing the processing difficulty of the sterilization tray and logistics system, clamping the powder-liquid dual-chamber bags to prevent them from falling off, and ensuring the conveying of the powder-liquid dual-chamber bags. Moreover, the powder-liquid dual-chamber bag clamps in this embodiment also fulfill the bag opening function: they can open and hold the bag opening. In addition, the powder-liquid dual-chamber bag clamps in this embodiment can also fulfill the gas filling function: by displacement, the sealed powder chamber is first evacuated to reduce the volume of the powder chamber, and then nitrogen is filled to further reduce the residual oxygen content. Furthermore, a nitrogen environment is set between the nitrogen filling and sealing stations to further ensure the reliability of the residual oxygen content.

[0034] Furthermore, in this embodiment, the bag cutting mechanism 05, weighing mechanism 13, bag opening mechanism 14, dispensing mechanism 06, inflation mechanism 07, and sealing mechanism 08 are located in a closed restricted access barrier system 02 (CRABS). The closed restricted access barrier system 02 can provide a sterile environment for bag cutting, weighing, bag opening, dispensing, inflation, and sealing, while also protecting operators and the external environment. The remaining mechanisms are located in an open restricted access barrier system 03 (ORABS) because the powder chamber is not open.

[0035] Specifically, the powder-liquid dual-chamber bag powder dispensing system provided by this utility model has an upper bag detection station, a bag cutting station, a dispensing station, a weighing station, a bag opening station, an inflation station, a sealing station, and a lower bag station arranged sequentially on the upper side of the frame 01. Each station is equipped with a corresponding device, namely an upper bag detection component, a bag cutting mechanism 05, a weighing mechanism 13, a bag opening mechanism 14, a dispensing mechanism 06, an inflation mechanism 07, a sealing mechanism 08, and a lower bag mechanism 09. The powder-liquid dual-chamber bag is suspended on the annular conveyor component by a clamp and rotates with it, driving the powder-liquid dual-chamber bag through each station to complete the entire powder filling process from upper bag to lower bag, which greatly improves the speed and efficiency of liquid-liquid dual-chamber bag dispensing. Furthermore, in order to ensure a sterile environment during powder dispensing, this utility model incorporates the weighing mechanism 13, the bag opening mechanism 14, the dispensing mechanism 06, the inflation mechanism 07, and the sealing mechanism 08 into a closed, restricted-entry isolation system 02, which ensures sterility during the dispensing process.

[0036] Preferably, the bag-loading detection component includes a robot arm 10 and a vision detection mechanism 11. The robot arm 10 can be set at the end of the annular conveyor 04 opposite to the conveying direction through the bag-loading mechanism for feeding material onto the annular conveyor. The vision detection mechanism 11 is used to detect whether the powder-liquid dual-chamber bag on the annular conveyor 04 is installed in place.

[0037] In this embodiment, the powder-liquid dual-chamber bag dispensing system specifically uses a robotic arm 10 to load the bags. The robotic arm 10 is located on one side of the end of the frame 01, that is, the end of the annular conveying mechanism 04 opposite to the conveying direction. It can grip the powder-liquid dual-chamber bag and transfer it to the powder-liquid dual-chamber bag fixture on the annular conveying mechanism 04. The vision inspection mechanism 11 is located on the frame 01 and to the right of the robotic arm 10, that is, the vision inspection mechanism 11 is located at the next station after the bag loading station. It can scan and inspect the powder-liquid dual-chamber bag gripped by the powder-liquid dual-chamber bag fixture on the annular conveying mechanism 04 to determine whether the powder-liquid dual-chamber bag is properly installed on the powder-liquid dual-chamber bag fixture. If it is detected that the powder-liquid dual-chamber bag is not properly installed on the powder-liquid dual-chamber bag fixture, the vision inspection mechanism 11 will transmit the information back to the controller and control the subsequent stations not to process the powder-liquid dual-chamber bag on the fixture.

[0038] Preferably, a cleaning mechanism 12 is provided between the upper bag mechanism and the bag cutting mechanism 05, and at the lower bag mechanism 09.

[0039] Understandably, in order to ensure the cleanliness of the powder chamber of the powder-liquid dual-chamber bag when it reaches the bag-cutting station for edge trimming, a cleaning mechanism 12 is set between the bag-up mechanism and the bag-cutting mechanism 05. The cleaning mechanism 12 can clean the powder-liquid dual-chamber bag and the powder-liquid dual-chamber bag clamp together, which can also ensure that the environment for subsequent powder dispensing remains clean and sterile. In addition, this embodiment also sets a cleaning mechanism 12 in the bag-down mechanism 09. This is to clean the powder-liquid dual-chamber bag clamp. After passing through the dispensing station, the inflation station and the sealing station, the powder-liquid dual-chamber bag clamp may have residual powder. Therefore, by setting a cleaning mechanism 12 at the bag-down mechanism 09, the powder-liquid dual-chamber bag clamp and the annular conveyor mechanism 04 that it passes through can be cleaned for subsequent reuse.

[0040] Preferably, the cleaning method of the cleaning mechanism 12 is ion wind cleaning.

[0041] In this embodiment, the cleaning mechanism 12 specifically uses ion wind for cleaning. Specifically, the cleaning mechanism 12 includes an electro-ionizer and a negative pressure suction device. The powder-liquid double-chamber bag holder carrying the powder-liquid double-chamber bag passes through the cleaning mechanism 12. The electro-ionizer generates electro-ions, which conduct electricity and remove the fibers or residual powder adhering to the waste edge of the powder-liquid double-chamber bag to be cut. Then, the fibers are extracted by the negative pressure suction device, thereby completing the cleaning.

[0042] As a preferred embodiment, the dispensing mechanism 06 specifically uses screw dispensing. The dispensing mechanism 06 includes a material cylinder, a powder feeding channel, and a dispensing section. The material cylinder and the dispensing section are connected through the powder feeding channel. A powder feeding screw is installed in the powder feeding channel. The powder feeding screw conveys the powder in the material cylinder to the dispensing section by rotating. The dispensing section is used to dispense the powder into the powder-liquid double-chamber bag.

[0043] In this embodiment, the screw-type dispensing system precisely controls the screw rotation angle to load the powder into the powder chamber, resulting in a wide filling range and minimal powder loss. The screw-type dispensing system employs a novel screw structure, a novel stirring structure, and a novel powder hopper installation structure, enabling high-precision dispensing.

[0044] As a preferred option, the dispensing mechanism 06 specifically uses airflow dispensing.

[0045] Of course, the dispensing mechanism 06 can also be selected as an airflow dispensing device according to the actual situation. Airflow dispensing uses vacuum to suck up the powder and compress it into the powder chamber, which can achieve micro-dispensing of 10-50mg and has a fast filling speed. Specifically, airflow dispensing adopts a rotary drum structure. During the metering and filling process, the metering mold will rotate counterclockwise in four stations. At station 1, the metering mold sucks up the material through vacuum; at station 3, the vacuum is disconnected and the material falls into the transfer bucket; at station 4, compressed air cleans the metering hole, completing one filling, and the rotation repeats.

[0046] Preferably, an online weighing mechanism 13 is provided between the dispensing mechanism 06 and the bag cutting structure. The weighing mechanism is used to check the weight of the powder dispensed by the dispensing mechanism 06.

[0047] In this embodiment, a new online weighing mechanism 13 is also set between the dispensing mechanism 06 and the bag cutting structure. Its sampling inspection can be fully automated, and the dispensing accuracy can be detected at regular intervals or in quantitative quantities. The dispensing strategy can be adjusted in a timely manner to ensure the accuracy and timeliness of dispensing.

[0048] Preferably, a light-type static eliminator is provided at position 06 of the dispensing mechanism.

[0049] Understandably, when the dispensing mechanism 06 is dispensing powder, the powder may be electrostatically adsorbed at the opening of the powder-liquid dual-chamber bag. Therefore, by using a photo-irradiated electrostatic elimination device with advanced "photoionization" technology, soft X-rays are generated during operation, and positive and negative ions are generated in "equal amounts" to quickly and efficiently eliminate static electricity. This prevents the powder carrying ions from adsorbing at the cut of the powder chamber of the powder-liquid dual-chamber bag due to electrostatic action, resulting in higher welding quality when the tail of the powder-liquid dual-chamber bag is subsequently heat-sealed.

[0050] Preferably, the annular conveying mechanism 04 includes a powder-liquid dual-chamber bag clamp, which is capable of opening or closing the bag opening of the powder-liquid dual-chamber bag when it moves to the bag opening mechanism 14, the dispensing mechanism 06, and the inflation mechanism 08.

[0051] In this embodiment, a novel powder-liquid dual-chamber bag clamp is provided, which can realize bag opening and closing, meeting the requirements of bag opening, dispensing, and inflation. Since the powder-liquid dual-chamber bag is a sterile product, it enters the sterile dispensing area after sterilization. This requires opening the powder chamber for bag opening, dispensing, and inflation processes. Only after opening the bag can the powder be smoothly dispensed into the powder chamber. The pharmaceutical powder needs to be inflated for protection, which also requires bag opening and inflation. This clamp, with the assistance of a bag support block and an external clamping mechanism, can realize the opening and closing of the bag. In addition, the powder-liquid dual-chamber bag clamp can be reinforced to prevent the bag from falling off. Furthermore, this invention reduces the processing difficulty and cost of upstream equipment. Currently, during the opening and closing process, bags may detach from the hanging pins, causing the bags to be unable to be transported normally, which greatly reduces the yield. In this embodiment, the powder-liquid dual-chamber bag clamp with added clamping device can ensure that the bags are fixed stably and reliably on the clamp, preventing them from detaching from the pins. In addition, the bags are positioned by positioning pins, which makes the processing of upstream sterilization trays and aseptic transfer equipment difficult and costly. With the addition of the clamping component, the upstream processes no longer need positioning pins, making it easier and cheaper to process the equipment.

[0052] This article also provides a method for dispensing powder in a dual-chamber bag system for dispensing powder and liquid, applicable to the aforementioned dual-chamber bag system for dispensing powder and liquid. The dispensing method includes:

[0053] The bag detection component transfers the powder-liquid dual-chamber bag to the annular conveyor mechanism 04 and detects whether the powder-liquid dual-chamber bag is installed in place.

[0054] The powder-liquid dual-chamber bag undergoes tail edge trimming via bag cutting mechanism 05;

[0055] The powder-liquid dual-chamber bag is weighed online by the weighing mechanism 13;

[0056] The powder chamber of the double-chamber bag is opened by the bag opening mechanism 14 in conjunction with the powder chamber bag clamp.

[0057] The powder-liquid dual-chamber bag is dispensed into the bag by the dispensing mechanism 06;

[0058] After the powder and liquid are dispensed, the double-chamber bag will be inflated by the inflation mechanism 07.

[0059] After being inflated, the powder and liquid double-chamber bag will be sealed by sealing mechanism 08;

[0060] The powder-liquid dual-chamber bag is removed from the ring mechanism via the bag-down mechanism 09.

[0061] Specifically, the following steps are performed sequentially according to the conveying direction of the circular conveyor mechanism 04: robot bag loading, visual inspection, ion air cleaning (simultaneously cleaning the powder-liquid dual-chamber bag clamp and the powder-liquid dual-chamber bag), bag cutting, weighing, bag opening, dispensing, inflation, sealing, cooling and unloading, ion air cleaning (cleaning the powder-liquid dual-chamber bag clamp), and robot bag loading again. When dispensing only one type of powder, to improve dispensing efficiency, a bag opening station can be set up in front of the dispensing station. The bag opening station can open the powder-liquid dual-chamber bag so that the subsequent dispensing mechanism 06 can dispense powder into the bag. When dispensing two types of powder, the bag opening mechanism 14 can be replaced by the dispensing mechanism 0. 6. The bag-opening station is replaced with a dispensing station. This allows the two dispensing stations to dispense different powders independently without affecting each other. Furthermore, the dispensing mechanism 06 at the dispensing station can be either screw dispensing or pneumatic dispensing. When pneumatic dispensing is selected, the weighing station and dispensing station are located together. The weighing station can perform timed weighing to check dispensing accuracy and adjust the dispensing strategy accordingly. When screw dispensing is selected, the weighing station is located between the bag-cutting station and the bag-opening station. The weighing tray of the weighing station can extend to the dispensing port under the dispensing station, allowing for timed sampling inspection of the powder dispensed by the dispensing mechanism 06 to check dispensing accuracy.

[0062] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0063] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
