Description

Technical Field

[0001] The utility model relates to the technical field of medical product packaging equipment, in particular to a double-chamber bag active folding device. Background Art

[0002] The powder-liquid dual-chamber bag utilizes a specialized process to package the drug powder and injection solvent in two separate chambers within the same bag. These two chambers are separated by a virtual weld, ensuring that the drug powder and solvent do not mix during storage and transportation. During clinical use, the operator simply squeezes the liquid chamber of the bag to break the virtual weld and connect the two chambers, allowing the drug powder and solvent to fully mix and dissolve. The bag can then be hung for infusion. The entire process does not require a dedicated preparation facility, is easy to operate, and requires minimal preparation time, earning widespread clinical recognition.

[0003] However, during transportation, the powder-liquid double-chamber bag may be squeezed. Since the formation of the two independent chambers is achieved through cold welding technology, when the extrusion force is large, the cold welding parts may open, causing the drug powder and injection solvent to mix prematurely or even break the bag. The premature mixing of drug powder and solvent may trigger a chemical reaction, causing drug degradation or the generation of new impurities. External microorganisms may also enter the bag, causing drug contamination, thereby affecting the efficacy and safety of the drug. Utility Model Content

[0029] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0030] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0031] See Figure 1 In the related art, a dual-chamber bag 500 typically includes a first chamber 510 and a second chamber 520, which are connected by a weld band 530. The inventors discovered during their research that during transportation or storage of the dual-chamber bag 500, the first chamber 510 and / or the second chamber 520 may be subjected to pressure. High pressure can cause the weld band 530 to detach, leading to premature mixing of the drug powder and the injection solvent, or even bag rupture, affecting the drug's efficacy and safety.

[0032] Based on the above situation, the embodiment of the present application discloses a double chamber bag active folding device. Figures 1 to 5 , the double-chamber bag active folding device provided in the embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0033] See Figure 2 、 Figure 3 and Figure 4 , an embodiment of the present application discloses an active folding device for a double-chamber bag, which includes a conveying mechanism 100, a pushing mechanism 200, a positioning assembly 300 and a frame 600, wherein the frame 600 is the basic component of the active folding device for the double-chamber bag, and can provide an installation basis for the conveying mechanism 100, the pushing mechanism 200 and the positioning assembly 300, that is, the conveying mechanism 100, the pushing mechanism 200 and the positioning assembly 300 can all be arranged on the frame 600, and the conveying mechanism 100 is used to convey the double-chamber bag 500. Exemplarily, the conveying mechanism 100 can be a belt transmission mechanism, and the double-chamber bag 500 is supported on the conveyor belt of the belt transmission mechanism.

[0034] In the embodiment of the present application, along the conveying direction of the conveying mechanism 100, the pushing mechanism 200 is provided on the first side of the conveying mechanism 100, and the positioning assembly 300 is provided on the second side of the conveying mechanism 100. It should be noted that the first side and the second side are opposite sides. For example, along the conveying direction of the conveying mechanism 100, the pushing mechanism 200 is provided on the left side of the conveying mechanism 100, and the positioning assembly 300 is provided on the right side of the conveying mechanism 100. The pushing mechanism 200 includes a driving assembly 210 and a pushing member 220 connected to the driving assembly 210. Under the driving action of the driving assembly 210, the pushing member 220 is used to abut against one side of the virtual welding strip 530 of the double-chamber bag 500 and push the side to fold over and overlap on the other side of the virtual welding strip 530 of the double-chamber bag 500. For example, see Figure 2 and Figure 4 The pushing piece 220 is used to abut against one side of the first bag chamber 510 of the double-chamber bag 500, and under the driving action of the driving assembly 210, the pushing piece 220 can push the first bag chamber 510 to lift and flip and fold to the other side around the virtual welding belt 530, so that the first bag chamber 510 and the second bag chamber 520 of the double-chamber bag 500 overlap with each other.

[0035] In an embodiment of the present application, the positioning assembly 300 can be fixed to the frame 600. During the process of the pushing mechanism 200 pushing the first bag chamber 510 to cause it to fold, the positioning assembly 300 can abut against the tail end of the second bag chamber 520 to play a positioning role, thereby preventing the double-chamber bag 500 from sliding off the conveying mechanism 100 from the second side of the conveying mechanism 100 under the action of the pushing force.

[0036] Based on the above technical solution, the pushing mechanism 200 is arranged on the first side of the conveying mechanism 100. When the double-chamber bag 500 continuously conveyed by the conveying mechanism 100 passes through the pushing mechanism 200, the driving component 210 can perform a driving action to drive the pushing member 220 to push the double-chamber bag 500 to fold around its virtual welding belt 530. The folded virtual welding belt 530 is clamped between the first bag chamber 510 and the second bag chamber 520, avoiding external pressure directly acting on the virtual welding belt 530, effectively improving the stability and safety of the virtual welding belt 530, thereby avoiding the solvent from breaking through the virtual welding belt 530 under pressure and causing the first bag chamber 510 and the second bag chamber 520 to penetrate, thereby ensuring the stability and safety of the drug; at the same time, the first bag chamber 510 and the second bag chamber 520 overlap with each other after folding, which can effectively reduce the space occupied by the double-chamber bag 500 and facilitate packaging, transportation and storage.

[0037] In an embodiment of the present application, the double-chamber bag 500 also includes a guide rail 400, which is arranged on the first side of the conveying mechanism 100, and the guide rail 400 is located upstream of the pushing mechanism 200. The guide rail 400 has a guide surface, which extends both along the conveying direction of the conveying mechanism 100 and upward in the longitudinal direction. The double-chamber bag 500 slides on the guide surface on one side of the virtual welding belt 530 (for example, the first bag chamber 510 or the head 540). Under the continuous conveying of the conveying mechanism 100, the side where the first bag chamber 510 is located is lifted, so that when the double-chamber bag 500 moves to the tail end of the guide rail 400, the first bag chamber 510 is located above the pushing member 220. In this way, the pushing member 220 can smoothly push the first bag chamber 510 to fold.

[0038] In the examples of this application, please continue to refer to Figure 2 and Figure 4The driving assembly 210 includes a bracket 211, an arm 212, a cantilever 213 and a cylinder 214, wherein the bracket 211 and the arm 212 can be fixedly arranged on the frame 600. For example, the bracket 211 can be a door frame-shaped structure extending in the longitudinal direction, the arm 212 can be a rod-shaped structure extending horizontally outward, one end of the cylinder 214 is hingedly mounted on the arm 212, and the other end of the cylinder 214 is connected to the aforementioned pushing member 220. The cylinder 214 is connected to the cantilever 220 from the door frame-shaped support arm. The cantilever 213 passes through the frame 211, one end of the cantilever 213 is rotatably connected to the frame 211, and the other end of the cantilever 213 is connected to the cylinder 214. In other words, the frame 211 can suspend the cylinder 214 through the cantilever 213, so that the power output end of the cylinder 214 is directed both upward and toward the second side of the conveying mechanism 100. When the cylinder 214 extends, the push member 220 can be lifted upward while pushing toward the second side, thereby achieving stable folding of the first bag chamber 510. In the above embodiment, the power source in the drive assembly 210 is the cylinder 214. Of course, in other embodiments of the present application, the power source in the drive assembly 210 can also be in the form of a motor, an electric push rod, etc., and the present application does not impose specific limitations on this.

[0039] In some embodiments of the present application, the pusher 220 may be a strip-shaped structure that can abut against the lower side of the first bag chamber 510 to push and fold the dual-chamber bag 500. In some embodiments of the present application, the pusher 220 may also be a plate-shaped structure. The plate-shaped pusher 220 has a larger contact area with the dual-chamber bag 500, which can effectively reduce the pressure per unit area during the folding process, thereby helping to reduce the risk of damage to the dual-chamber bag 500 due to excessive local pressure.

[0040] Please continue to see Figure 1 In the related art, the dual-chamber bag 500 further includes a head 540 and a neck 550. The head 540 is connected to the first bag chamber 510 through the neck 550, and the radial dimension of the head 540 is larger than the radial dimension of the neck 550. Based on the structural features of the dual-chamber bag 500, in the further technical solutions of this application, please refer to Figure 4 and Figure 5In the case that the pushing piece 220 is a plate structure, the pushing piece 220 comprises a first plate body 221 and a second plate body 222 connected with the first plate body 221, the second plate body 222 is arranged in a bent manner relative to the first plate body 221, and the second plate body 222 and the first plate body 221 are in an arc transition, and the arc transition between the first plate body 221 and the second plate body 222 corresponds to the neck portion 550; in this way, when the pushing piece 220 pushes the double-chamber bag 500, the arc transition between the first plate body 221 and the second plate body 222 can be just clamped in the position where the neck portion 550 is located, at this time, the head portion 540 and the first bag chamber 510 can respectively limit the pushing piece 220 on both sides of the neck portion 550, thereby effectively avoiding the mutual disengagement of the pushing piece 220 and the double-chamber bag 500, so that the double-chamber bag 500 can be stably pushed by the pushing piece 220 and be folded.

[0041] In the embodiments of the present application, please continue to refer to Figure 2 and Figure 3 The conveying mechanism 100 comprises a driving piece 110, a driving roller 120, a driven roller 130 and a conveying belt 140, wherein the conveying belt 140 is arranged around the driving roller 120 and the driven roller 130, the driving piece 110 is connected with the driving roller 120 to drive the driving roller 120 to rotate, and the driving piece 110 can be a motor, for example, the motor can be connected with the rotating shaft of the driving roller 120 through a speed reducer and a shaft coupling, thereby driving the driving roller 120 to rotate and driving the conveying belt 140 to rotate, and the double-chamber bag 500 is supported on the upper surface of the conveying belt 140.

[0042] In further technical solutions, the distance between the driving roller 120 and the driven roller 130 is adjustable, the distance between the driving roller 120 and the driven roller 130 is adjusted, thereby adjusting the tension of the conveying belt 140, so that the conveying belt 140 can stably support the double-chamber bag 500. For example, the conveying mechanism 100 further comprises a first mounting seat and a second mounting seat, the driving roller 120 is rotatably arranged on the first mounting seat, and the driven roller 130 is rotatably arranged on the second mounting seat, the first mounting seat is provided with a first mounting groove extending in a first direction, the second mounting seat is provided with a first mounting groove extending in the first direction, a threaded connecting piece passes through the first mounting groove and is threadedly connected with the rack 600 to realize mounting and fixing of the first mounting seat, and the threaded connecting piece passes through the second mounting groove and is threadedly connected with the rack 600 to realize mounting and fixing of the second mounting seat. In the embodiments of the present application, the first direction is the conveying direction of the conveying mechanism 100, and by adjusting the relative positions of the first mounting seat and / or the second mounting seat and the rack 600, the tension of the conveying belt 140 can be adjusted.

[0043] In a further technical solution, the double-chamber bag active folding device of the embodiment of the present application may also include a support plate 150. Specifically, the support plate 150 can be connected and fixed to the frame 600, and the support plate 150 is located in the space formed by the conveyor belt 140, and the support plate supports the upper side of the conveyor belt 140. During the process of conveying the double-chamber bag 500 by the conveyor belt 140, the support plate 150 provides a solid support base for the conveyor belt 140. When subjected to the weight of the double-chamber bag 500 or possible external forces, the support plate 150 can provide a stable support surface to limit the deviation and vibration of the conveyor belt 140, thereby ensuring the stability and accuracy of the transmission of the double-chamber bag 500, avoiding the double-chamber bag 500 from having a large deflection on the conveyor belt 140, and thus ensuring the stability of the transmission of the double-chamber bag 500, avoiding the double-chamber bag 500 from having a large posture change so that the push piece 220 cannot accurately contact the double-chamber bag 500 on one side of the first bag chamber 510, and also avoiding the double-chamber bag 500 from tipping over during the folding process and separating from the push piece 220 in advance, resulting in folding failure.

[0044] In a further technical solution, the conveying mechanism 100 also includes a partition 160, and multiple partitions 160 are arranged at intervals on the conveyor belt 140. A accommodating area for accommodating the double-chamber bag 500 is formed between two adjacent partitions 160. That is to say, two adjacent double-chamber bags 500 are spaced apart by the partition 160. In this way, interference and overlapping of the two adjacent double-chamber bags 500 can be effectively avoided, thereby ensuring the stability of the folding of the double-chamber bag 500.

[0045] In an embodiment of the present application, the positioning assembly 300 includes a first limit plate 310, which can be connected and fixed to the frame 600 and distributed on the second side of the conveying mechanism 100. The first limit plate 310 is extended along the first direction. When the pushing member 220 pushes the first bag chamber 510 to cause it to fold, the entire double-chamber bag 500 is pushed toward the second side of the conveying mechanism 100. The first limit plate 310 can cooperate with the tail end of the second bag chamber 520 in the second direction. The second direction is a vertical direction perpendicular to the first direction in the horizontal plane, thereby avoiding the double-chamber bag 500 from detaching from the conveyor belt 140.

[0046] In some embodiments of the present application, the positioning assembly 300 can further comprise a second limiting plate 320, which can be connected with the rack 600 or connected with the first limiting plate 310. The second limiting plate 320 is arranged on the second side of the conveying mechanism 100 and extends along the first direction to limit the second bag chamber 520 in the third direction. The first direction, the second direction and the third direction are perpendicular to each other. For example, the third direction can be the longitudinal direction. The second limiting plate 320 can limit the tail end of the second bag chamber 520 in the third direction, so as to prevent the tail end of the second bag chamber 520 from being pushed out by the outward pushing piece 220.
