Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a continuous blood bag filling and sealing production system. The present invention also relates to a continuous blood bag filling and sealing production process. Background Art

[0002] With the development of China's medical level, various medical equipment has been widely used.

[0003] Blood bags are a common medical device used to collect and store blood for blood bank storage. Made primarily of medical-grade materials, they are soft and elastic, making them a flexible bag.

[0004] At present, blood bag filling and sealing operations all use manual equipment. The operator holds the blood bag hose and hangs it directly to the vacuum nozzle for vacuuming. After vacuuming, the operator still needs to hold the blood bag hose and pinch the hose hard to maintain the vacuum. Then the blood bag is transferred to the filling machine, the blood bag hose is hung on the filling nozzle, and then the hose and filling nozzle are pinched with one hand, and the filling machine is operated with the other hand to fill the blood bag with blood. Finally, the filled blood bag is transferred to the sealing machine, and the sealing machine is operated to perform high-frequency welding and sealing on the blood bag hose to complete the entire filling and sealing operation.

[0005] However, manually holding blood bags for vacuuming, filling, sealing and other processes not only requires a large amount of manual labor and a heavy workload for workers, but also has low production efficiency. Workers need to move back and forth continuously at multiple operating equipment, which can easily cause mutual contamination between different areas of the production workshop. In addition, when working, workers' hands directly touch the hose parts of the blood bags many times, which can easily bring harmful substances such as external bacteria, viruses, dust, etc. into the blood bags, causing blood contamination, especially at the filling machine position, which can easily cause the workshop production operations to not meet the GMP (Good Manufacturing Practice of Medical Products) certification requirements.

[0006] Therefore, how to improve the mechanization level of blood bag production operations, reduce manual labor load, improve production efficiency, and reduce operational pollution are technical problems faced by those skilled in the art. Summary of the Invention

[0007] The present invention aims to provide a continuous blood bag filling and sealing production system that can improve the mechanization level of blood bag production operations, reduce manual labor load, improve production efficiency, and reduce operational pollution. Another object of the present invention is to provide a continuous blood bag filling and sealing production system.

[0017] Preferably, the method further comprises a first intermediate transfer station disposed between the vacuuming station and one end of the production track for transferring the vacuumed blood bag to the production track.

[0018] Preferably, it also includes a second intermediate transfer station arranged between the unloading station and the other end of the production track, for transferring the sealed blood bags to the unloading station.

[0019] Preferably, the filling station comprises a positioning mechanism for directional clamping and fixing the blood bag, and a filling nozzle for inserting into a hose of the blood bag and performing blood filling.

[0020] Preferably, the sealing station comprises a sealing mold for clamping the hose of the blood bag and heating, welding and plastic-sealing it.

The sealing station is mainly used to seal the hoses of the blood bags after filling, to achieve sealing of the blood bags, to form a sealed protection for the blood stored in the blood bags, and to prevent external pollution sources from entering the blood bags. The unloading station is mainly used to unload and output the sealed blood bags to complete the blood bag production operation. Thus, the continuous blood bag filling and sealing production system provided by the present invention loads blood bags at a loading station, then sequentially passes through vacuuming, filling, and sealing stations for vacuuming, canning, and sealing. Finally, the finished product is discharged at the unloading station. During this process, blood bags flow orderly through each station, each performing its own operations, eliminating the need for manual intervention. This increases the mechanization of blood bag production, reduces labor burden, and improves production efficiency. Furthermore, workers no longer need to travel back and forth between stations, reducing pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0035] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the overall structure of a specific implementation method provided by the present invention.

[0036] In a specific embodiment provided by the present invention, the continuous blood bag filling and sealing production system mainly includes a loading station 1, a vacuum station 2, a filling station 3, a sealing station 4 and a unloading station 5.

[0037] Among them, the loading station 1 is mainly used to load empty blood bags to realize blood bag loading.

[0038] The vacuum station 2 is mainly used to vacuum the loaded blood bags to ensure that there are no other impurities inside the blood bags before filling.

[0039] The filling station 3 is mainly used to fill the vacuumed blood bag to fill the blood into the blood bag and reach the target blood storage volume.

[0040] The sealing station 4 is mainly used to seal the hose of the blood bag after filling, so as to seal the blood bag and form a sealed protection for the blood stored in the blood bag to prevent external pollution sources from entering the blood bag.

[0041] The unloading station 5 is mainly used for unloading and outputting the sealed blood bags to complete the blood bag production operation.

[0042] Thus, the continuous blood bag filling and sealing production system provided in this embodiment loads blood bags at loading station 1, then sequentially passes through vacuuming station 2, filling station 3, and sealing station 4 for vacuuming, canning, and sealing. Finally, the finished product is discharged at unloading station 5. During this process, blood bags flow through the various stations in an orderly manner, each performing its own operations without manual intervention. This increases the mechanization of blood bag production, reduces labor burden, and improves production efficiency. Furthermore, workers no longer need to travel back and forth between stations, thus reducing pollution.

[0043] In an optional embodiment of the loading station 1, the loading station 1 primarily comprises a loading conveyor. Specifically, the loading conveyor is primarily used to transport empty blood bags, sequentially transporting them to the vacuum station 2 for loading. Typically, the empty blood bags are arranged in an orderly manner on the loading conveyor to facilitate orderly loading and subsequent transport. Typically, the loading conveyor utilizes synchronous pulleys, chain belts, or a spiral conveyor.

[0044] In an optional embodiment of the vacuum station 2, the vacuum station 2 mainly includes a bag insertion rod and a vacuum suction nozzle. Among them, the bag insertion rod is mainly used to achieve clamping and fixing of the blood bag, and specifically, it can be inserted into the blood bag from the hose pipe opening of the blood bag through the bag insertion rod. The vacuum suction nozzle is provided at the front end of the bag insertion rod and is inserted into the blood bag along with the bag insertion rod. It is mainly used to vacuum the interior of the blood bag through negative pressure suction to discharge air, impurities, etc. in the blood bag. Generally, at the vacuum station 2, the empty blood bags transported from the loading station 1 can be hung on the bag insertion rod manually, or a plurality of empty blood bags can be clamped on the bag insertion rod by a robotic arm.

[0045] In an optional embodiment of the filling station 3, the filling station 3 primarily comprises a positioning mechanism and a filling nozzle. The positioning mechanism is primarily used to position, clamp, and secure the blood bag, ensuring that it remains fixed during blood filling. Specifically, the positioning mechanism can employ a clamp or other component to clamp and secure the blood bag's hose, maintaining the hose's opening facing upward. The filling nozzle's interior is connected to a blood source, enabling blood to be drawn out. It is primarily intended to be inserted into the blood bag's hose for blood filling. Generally, the opening of the filling nozzle is maintained downward to mate with the blood bag's hose, which has its opening facing upward.

[0046] In an optional embodiment of the sealing station 4, the sealing station 4 primarily comprises a sealing mold. Specifically, the sealing mold is primarily used to clamp the blood bag's flexible tube and heat and weld it to seal the blood bag's flexible tube. Generally, the sealing mold may include two semicircular clamping rings with a built-in heating element. After the two clamping rings clamp the flexible tube, the heating element heats the tube, welding and sealing it.

[0047] To facilitate the continuous flow of blood bags between the filling station 3 and the sealing station 4, a production track 6 is added in this embodiment. Specifically, the production track 6 can be a flow line or a belt conveyor, enabling continuous transport of blood bags, allowing the blood bags to flow sequentially along the production track 6 through the filling station 3 and the sealing station 4. Accordingly, the filling station 3 and the sealing station 4 are integrated on the production track 6 and arranged in a sequential order to conform to the flow order of the blood bags on the production track 6.

[0048] Furthermore, to facilitate the flow of blood bags between the vacuum station 2 and the filling station 3, a first intermediate transfer station 7 is added in this embodiment. Specifically, the first intermediate transfer station 7 is located between the vacuum station 2 and one end (the head end) of the production track 6. It is mainly used to transfer the vacuumed blood bags from the vacuum station 2 to the production track 6, and then use the production track 6 to continue to transfer the blood bags to the filling station 3.

[0049] Similarly, to facilitate the flow of blood bags between the sealing station 4 and the unloading station 5, a second intermediate transfer station 8 is also provided in this embodiment. Specifically, the second intermediate transfer station 8 is located between the unloading station 5 and the other end (the tail end) of the production track 6. It is primarily used to transfer sealed blood bags from the sealing station 4 to the unloading station 5.

[0050] In summary, the coordinated transport of blood bags between the production track 6, the first intermediate transfer station 7, and the second intermediate transfer station 8 enables the automated and orderly flow of blood bags among all stations in the production system, enabling continuous production of blood bags. Furthermore, the production track 6, the first intermediate transfer station 7, the second intermediate transfer station 8, and each station maintain a signal connection with the control cabinet 10, allowing the industrial computer to automatically control the operating status of the entire production system based on the actual production progress.

[0051] In addition, considering that some manual labor may be required at the vacuum station 2, in order to prevent workers from causing contamination to the adjacent filling station 3 when they are active at the vacuum station 2, this embodiment also provides an isolation plate 9 between the vacuum station 2 and the filling station 3. The isolation plate 9 isolates the vacuum station 2 and the filling station 3 from each other, thereby preventing workers from accidentally entering the filling station 3 and preventing harmful pollution sources from entering the filling station 3.

[0052] like Figure 2 As shown, Figure 2 The present invention provides a process flow diagram of a specific embodiment of the present invention.

[0053] This embodiment also provides a continuous blood bag filling and sealing production process, which is applied to the above-mentioned continuous blood bag filling and sealing production system, and mainly includes five steps: loading the blood bag; vacuuming the loaded blood bag; filling the vacuumed blood bag; sealing the hose of the filled blood bag; and unloading the sealed blood bag.

[0054] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
