Description

Technical Field

[0001] The utility model relates to the technical field of medical product packaging equipment, in particular to a double-chamber bag track type bag 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

[0028] 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.

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.

[0030] See Figure 1 In the related art, a dual-chamber bag 500 typically includes a first bag chamber 510 and a second bag chamber 520, which are connected by a weld band 530. During research, the inventors discovered that during transportation or storage of the dual-chamber bag 500, the first bag chamber 510 and / or the second bag chamber 520 may be subjected to pressure. When the pressure is high, the weld band 530 may detach, causing the drug powder and injection solvent in the first bag chamber 510 and the second bag chamber 520 to mix prematurely or even break the bag, affecting the efficacy and safety of the drug.

[0031] Based on the above situation, the embodiment of the present application discloses a double-chamber bag track type bag folding device. Figures 1 to 4 , the double-chamber bag track-type bag folding device provided in the embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0032] See Figure 2 、 Figure 3 and Figure 4The embodiment of the present application discloses a double-chamber bag track-type bag folding device, which includes a conveying mechanism 100, a guide assembly 200, a positioning assembly 300 and a frame 400, wherein the frame 400 is the basic component of the double-chamber bag track-type bag folding device, and can provide an installation base for the conveying mechanism 100, the guide assembly 200 and the positioning assembly 300. The conveying mechanism 100 is used to convey the double-chamber bag 500. For example, 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. Along the conveying direction of the conveying mechanism 100, the guide assembly 200 is provided on a first side of the conveying mechanism 100. Specifically, the guide assembly 200 includes a guide rail 210. The guide rail 210 can be provided above the conveying mechanism 100, and the guide rail 210 is extended along the first direction, the second direction and the third direction at the same time. The conveying direction of the conveying mechanism 100 is defined as the first direction, and the first direction, the second direction and the third direction are perpendicular to each other. For example, the first direction can be a lateral direction in a horizontal plane, the second direction can be a vertical direction perpendicular to the first direction in the horizontal plane, and the third direction can be a longitudinal direction. The guide rail 210 is used to slide with the double-chamber bag 500 on one side of its virtual welding belt 530. For example, the guide rail 210 slides with the double-chamber bag 500 on one side of the first bag chamber 510. When the double-chamber bag 500 is continuously conveyed by the conveying mechanism 100, the guide rail 210 can guide 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.

[0033] In an embodiment of the present application, the positioning assembly 300 can be arranged on the frame 400 and distributed on the second side of the conveying mechanism 100. For example, the first side and the second side can be the left and right sides of the conveying mechanism 100 in the conveying direction. When the first bag chamber 510 is lifted by the guide rail 210, the positioning assembly 300 is arranged on the second side and is used to stop with the end of the second bag chamber 520 facing away from the first bag chamber 510 (that is, the tail end of the second bag chamber 520). When the guide rail 210 is lifted and the first bag chamber 510 is flipped over, the entire double-chamber bag 500 will be subjected to a thrust along the second direction. Based on the stopping and positioning effect of the positioning assembly 300 on the second bag chamber 520, the double-chamber bag 500 can be effectively prevented from sliding off from the second side of the conveying mechanism 100.

[0034] Based on the above technical solution, the guide rail 210 is arranged on the first side of the conveying mechanism 100 and extends above the conveying mechanism 100. Based on the guiding function of the guide rail 210, the double-chamber bag 500 continuously conveyed by the conveying mechanism 100 can be automatically folded when passing through the guide rail 210. The folded virtual welding tape 530 is clamped between the first bag chamber 510 and the second bag chamber 520, avoiding the external pressure from directly acting on the virtual welding tape 530, effectively improving the stability and safety of the virtual welding tape 530, thereby avoiding the solvent from breaking through the virtual welding tape 530 under pressure and causing the first bag chamber 510 and the second bag chamber 520 to be connected, 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.

[0035] In an embodiment of the present application, the conveying mechanism 100 includes a driving member 110, an active roller 120, a driven roller 130 and a conveyor belt 140, wherein the conveyor belt 140 is wound around the active roller 120 and the driven roller 130, and the driving member 110 is connected to the active roller 120 to drive the active roller 120 to rotate. For example, the driving member 110 can be a motor, which can be connected to the rotating shaft of the active roller 120 through a reducer and a coupling, thereby driving the active roller 120 to rotate, and then driving the conveyor belt 140 to rotate to transport the double-chamber bag 500 supported on its upper surface.

[0036] In a further technical solution, the spacing between the active roller 120 and the driven roller 130 is adjustable. By adjusting the spacing between the active roller 120 and the driven roller 130, the tension of the conveyor belt 140 can be adjusted, so that the conveyor belt 140 can provide stable support for the double-chamber bag 500. For example, the conveying mechanism 100 further includes a first mounting seat and a second mounting seat. The active roller 120 is rotatably mounted on the first mounting seat, and the driven roller 130 is rotatably mounted on the second mounting seat. The first mounting seat is provided with a first mounting groove extending in a first direction, and the second mounting seat is provided with a second mounting groove extending in the first direction. A threaded connector passes through the first mounting groove and threadedly engages with the frame 400 to secure the first mounting seat. The threaded connector passes through the second mounting groove and threadedly engages with the frame 400 to secure the second mounting seat. The tension of the conveyor belt 140 can be adjusted by adjusting the relative position of the threaded connector with respect to the first mounting seat and / or the second mounting seat.

[0037] In a further technical solution, the double-chamber bag track-type bag folding device of the embodiment of the present application may further include a support plate 150. Specifically, the support plate 150 may be connected and fixed to the frame 400, and the support plate 150 is located in the space formed by the conveyor belt 140, and the support plate 150 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, preventing the double-chamber bag 500 from being significantly deflected on the conveyor belt 140, and further ensuring that the double-chamber bag 500 can be transmitted to the guide rail 210 in a correct posture for folding.

[0038] 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.

[0039] Please continue to see Figure 1 In the relevant technical field, the double-chamber bag 500 also 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 greater than the radial dimension of the neck 550. In the embodiment of the present application, the guide rail 210 can be a rod-shaped component. When the double-chamber bag 500 passes through the guide rail 210, the guide rail 210 is clamped at the position where the neck 550 is located. Based on the limiting effect of the first bag chamber 510 and the head 540 on both sides of the neck 550, the guide rail 210 and the double-chamber bag 500 can be effectively prevented from separating from each other, so that the double-chamber bag 500 can move stably along the guide rail 210 and fold over.

[0040] In the examples of this application, please continue to refer to Figure 2 and Figure 4The guide assembly 200 may further include a guide plate 220 and a bracket 230. Along the conveying direction of the conveying mechanism 100, the guide plate 220 is disposed upstream of the guide rail 210, and the bracket 230 is disposed downstream of the guide rail 210. The leading end of the guide rail 210 is connected to the guide plate 220, and the trailing end of the guide rail 210 is connected to the bracket 230. In other words, the guide plate 220 and the bracket 230 may serve as intermediate adapters to connect the guide rail 210 to the frame 400. The guide plate 220 has a guide surface that extends both along the conveying direction of the conveying mechanism 100 and upward in the longitudinal direction. The first bag chamber 510 or the head 540 may be slidably engaged with the guide surface. The guide plate 220 may pre-lift the dual-chamber bag 500, allowing the rod-shaped guide rail 210 to be smoothly transferred to the dual-chamber bag 500.

[0041] In a further technical solution, the position of the guide plate 220 in the first direction is adjustable. For example, a slot extending along the first direction is provided on the guide plate 220. The guide plate 220 can be slidably arranged on the frame 400 along the first direction. The threaded connector can pass through the slot and engage with the frame 400 through a thread, thereby achieving the connection and fixation between the guide plate 220 and the frame 400. When the position of the guide plate 220 needs to be adjusted, it is only necessary to loosen the threaded connector, slide the guide plate 220 to an appropriate position, and then re-lock it. When the dual-chamber bag 500 is in contact with the guide rail 210 for a longer time, the folding process is relatively smooth. However, when the guide rail 210 extends less in the first direction, the contact time of the dual-chamber bag 500 is shorter, and the folding process is relatively rapid. By adjusting the position of the guide plate 220 in the first direction, the extension length of the guide rail 210 in the first direction can be adjusted, thereby adjusting the speed of the folding of the dual-chamber bag 500. This prevents the dual-chamber bag 500 from turning over too quickly and causing an uncertain overlapping posture, while also preventing it from turning over too slowly and affecting folding efficiency. Of course, in some optional embodiments of the present application, the speed of the folding of the dual-chamber bag 500 can also be adjusted by adjusting the position of the bracket 230 in the first direction, which will not be described in detail here.

[0042] In some optional embodiments of the present application, the position of the bracket 230 in the third direction is adjustable. By adjusting the position of the bracket 230 in the third direction, the extension height of the guide rail 210 can be adjusted. In this way, the double-chamber bag track-type bag folding device can be compatible with the folding requirements of double-chamber bags 500 of different sizes. It should be noted that for double-chamber bags 500 of different sizes, before folding, their necks 550 should correspond to the head end of the guide rail 210 to ensure that they can be guided and folded.

[0043] In some optional embodiments of the present application, the position of the tail end of the guide rail 210 in the second direction is adjustable. By adjusting the position of the tail end of the guide rail 210 in the second direction, the posture of the dual-chamber bag 500 when separated from the guide rail 210 can be adjusted. For example, a crimping joint is provided at the tail end of the rod-shaped guide rail 210. The crimping joint can be locked to the bracket 230 via a threaded connection to achieve crimping and fixing of the tail end of the guide rail 210. After loosening the crimping joint, the position of the tail end of the guide rail 210 in the second direction can be adjusted by sliding, and after adjusting to a suitable position, the crimping and fixing can be re-engaged.

[0044] It is understood that when the dual-chamber bag 500 separates from the guide rail 210, the first bag chamber 510 should deflect by an angle greater than 90°, or even more, such as within a range of 120° to 150°, to avoid the first bag chamber 510 failing to properly flip over and accurately overlap the second bag chamber 520. It should be noted that in some embodiments of the present application, the operator can also manually adjust the posture of the entire guide rail 210 to accommodate dual-chamber bags 500 of different sizes and types.

[0045] Please continue to see Figure 4 The bracket 230 includes a first section 231 and a second section 232 connected to the first section 231. The second section 232 is bent relative to the first section 231 so that the entire bracket 230 is L-shaped. The first section 231 is provided with a first long groove extending along its extension direction, and the second section 232 is provided with a second long groove extending along its extension direction. For example, when the bracket 230 is set on the rack 400, the first section 231 extends along the third direction, and the second section 232 extends along the second direction. The extension direction of the first section 231 is perpendicular to the extension direction of the second section 232. The first long groove passes through the first section 231, and the threaded connector can pass through the first long groove to be connected and fixed to the rack 400. The tail end of the guide rail 210 slides with the second long groove and can be crimped and fixed by the crimping head.

[0046] Based on the above scheme, the position and posture of the guide rail 210 can be adjusted in three directions, so that the guide rail 210 can realize folding actions of different speeds for double-chamber bags 500 of different sizes. While ensuring that double-chamber bags 500 of different sizes can be folded stably, the folding efficiency of the entire track-type bag folding device for the double-chamber bags can also be guaranteed.

[0047] 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 400 and distributed on the side of the conveyor belt 140 corresponding to the second bag chamber 520. When the guide rail 210 lifts the side where the first bag chamber 510 is located, the entire double-chamber bag 500 is subjected to a thrust along the second direction, and the first limit plate 310 can cooperate with the tail end of the second bag chamber 520 in the second direction, thereby avoiding the double-chamber bag 500 from detaching from the conveyor belt 140.

[0048] In some embodiments of the present application, the positioning assembly 300 may further include a second limit plate 320, which may be connected to the frame 400, or the second limit plate 320 may be connected to the first limit plate 310, and the second limit plate 320 and the first limit plate 310 are distributed on the same side of the conveying mechanism, and the second limit plate 320 can cooperate with the tail end of the second bag chamber 520 in the third direction to prevent the tail end of the second bag chamber 520 from tilting up and being pushed outward by the guide rail 210.

[0049] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in the opposite order according to the functions involved.
